How to get smtp email log

I want to get a log when I email to the wrong email address.
so, I wrote this command.
mailserver = mymailserver
to_email = emailaddress
from_email = fromaddress
subject = SBJECT
original_message = TEXT
message = MESSAGE
server = smtplib.SMTP(mailserver)
debug = server.set_debuglevel(1)
server.sendmail(from_mail,to_mail, message)
server.quit()
print(debug)
I just want to know connection status log.
wchich code should I edit?
I tried this scripts, but it does not work well.
server = smtplib.SMTP(mailserver)
mail_response = server.sendmail(from_mail,to_mail, message)
server.quit()
print(mail_response)
Thank you for helping me.

Try This and read the docs. Hope it will help you
# Import smtplib for the actual sending function
import smtplib
# Import the email modules we'll need
from email.message import EmailMessage
# Open the plain text file whose name is in textfile for reading.
# Or simply skip this part
with open(textfile) as fp:
# Create a text/plain message
msg = EmailMessage()
msg.set_content(fp.read())
# me == the sender's email address
# you == the recipient's email address
msg['Subject'] = f'The contents of {textfile}'
msg['From'] = me
msg['To'] = you
# Send the message via our own SMTP server.
s = smtplib.SMTP('localhost')
s.send_message(msg)
s.quit()

Python smtplib: only the first email out of several arrives to destination

I have put together a function send_email [1] to send emails with support for plain-text and html messages. It works well, but I have an issue I don't quite know how to debug. My system has sendmail as its MTA.
The function is called in a for loop, as follows:
for data in data_set:
subject, message = process(data) # Irrelevant stuff
send_email(subject, message, "fixed#email.address")
In the debug output of smtplib [1] I see that all calls to send_email completed successfully. The weird behavior is:
If the message is "short" (I tested with a single line), all sent messages actually arrive to fixed#email.address
If the message is "not short" (that is, the multiple lines I generate with the real process_data function), only the first email does arrive, while the others don't, even though the debug output of smtplib in [1] reports success for each and all of the emails.
If the message is equally "not short" but the destination address is different for each message, then all messages arrive to their intended destinations.
For the latter case, the for loop would look like:
addresses = ["fixed#email.address", "fixed.2#email.address", ...]
for data, addr in zip(data_set, addresses):
subject, message = process(data) # Irrelevant stuff
send_email(subject, message, addr)
The intended behavior is of course different addresses for different data, but I'm concerned that not understanding why this happens might bite me in an unexpected way later on.
[1] My send mail function:
import smtplib
import socket
import getpass
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
def send_email (subject, message, to, reply_to='', cc='', html_message=''):
COMMASPACE = ", "
user, host = get_user_and_host_names()
sender = '%s#%s' % (user, host)
receivers = make_address_list(to)
copies = make_address_list(cc)
msg = MIMEMultipart('alternative')
msg['Subject'] = subject
msg['From'] = sender
msg['To'] = COMMASPACE.join(receivers)
if reply_to:
msg.add_header('Reply-to', reply_to)
if len(copies):
msg.add_header('CC', COMMASPACE.join(copies))
# According to RFC 2046, the last part of a multipart message, in this case
# the HTML message, is best and preferred.
if message:
msg.attach( MIMEText(message, 'plain'))
if html_message:
msg.attach( MIMEText(html_message, 'html'))
smtpObj = smtplib.SMTP('localhost')
smtpObj.set_debuglevel(1)
smtpObj.sendmail(sender, receivers, msg.as_string())
smtpObj.quit()
print "\nSuccessfully sent email to:", COMMASPACE.join(receivers)
def get_user_and_host_names():
user = getpass.getuser()
host = socket.gethostname()
return user, host
def make_address_list (addresses):
if isinstance(addresses, str):
receivers = addresses.replace(' ','').split(',')
elif isinstance(addresses, list):
receivers = addresses
return receivers

A working solution I had for sending email:
from email.MIMEMultipart import MIMEMultipart
from email.MIMEBase import MIMEBase
from email.MIMEText import MIMEText
from email.Utils import COMMASPACE, formatdate
from email import Encoders
import smtplib
class EMail(object):
""" Class defines method to send email
"""
def __init__(self, mailFrom, server, usrname, password, files, debug=False):
self.debug = debug
self.mailFrom = mailFrom
self.smtpserver = server
self.EMAIL_PORT = 587
self.usrname = usrname
self.password = password
def sendMessage(self, subject, msgContent, files, mailto):
""" Send the email message
Args:

msgContent(string): email message Content
files(List): list of files to be attached

"""
msg = self.prepareMail(subject, msgContent, files, mailto)
# connect to server and send email
server=smtplib.SMTP(self.smtpserver, port=self.EMAIL_PORT)
server.ehlo()
# use encrypted SSL mode
server.starttls()
# to make starttls work
server.ehlo()
server.login(self.usrname, self.password)
server.set_debuglevel(self.debug)
try:
failed = server.sendmail(self.mailFrom, mailto, msg.as_string())
except Exception as er:
print er
finally:
server.quit()
def prepareMail(self, subject, msgHTML, attachments, mailto):
""" Prepare the email to send
Args:
subject(string): subject of the email.
msgHTML(string): HTML formatted email message Content.
attachments(List): list of file paths to be attached with email.
"""
msg = MIMEMultipart()
msg['From'] = self.mailFrom
msg['To'] = mailto
msg['Date'] = formatdate(localtime=True)
msg['Subject'] = subject
#the Body message
msg.attach(MIMEText(msgHTML, 'html'))
msg.attach(MIMEText("Add signature here"))
if attachments:
for phile in attachments:
# we could check for MIMETypes here
part = MIMEBase('application',"octet-stream")
part.set_payload(open(phile, "rb").read())
Encoders.encode_base64(part)
part.add_header('Content-Disposition', 'attachment; filename="%s"' % os.path.basename(phile))
msg.attach(part)
return msg
I hope this helps.

My Working solution to format your list in this manner (after many hours of experiment):
["firstemail#mail.com", "secondmail#mail.com", "thirdmail#email.com"]
I used:
to_address = list(str(self.to_address_list).split(","))
to convert my QString into string then into list with splitting with a ","
In my case COMMASPACE was not working, because on splitting a space was already added by default.

Python: "subject" not shown when sending email using smtplib module

I am successfully able to send email using the smtplib module. But when the emial is sent, it does not include the subject in the email sent.
import smtplib
SERVER = <localhost>
FROM = <from-address>
TO = [<to-addres>]
SUBJECT = "Hello!"
message = "Test"
TEXT = "This message was sent with Python's smtplib."
server = smtplib.SMTP(SERVER)
server.sendmail(FROM, TO, message)
server.quit()
How should I write "server.sendmail" to include the SUBJECT as well in the email sent.
If I use, server.sendmail(FROM, TO, message, SUBJECT), it gives error about "smtplib.SMTPSenderRefused"

Attach it as a header:
message = 'Subject: {}\n\n{}'.format(SUBJECT, TEXT)
and then:
server = smtplib.SMTP(SERVER)
server.sendmail(FROM, TO, message)
server.quit()
Also consider using standard Python module email - it will help you a lot while composing emails. Using it would look like this:
from email.message import EmailMessage
msg = EmailMessage()
msg['Subject'] = SUBJECT
msg['From'] = FROM
msg['To'] = TO
msg.set_content(TEXT)
server.send_message(msg)

This will work with Gmail and Python 3.6+ using the new "EmailMessage" object:
import smtplib
from email.message import EmailMessage
msg = EmailMessage()
msg.set_content('This is my message')
msg['Subject'] = 'Subject'
msg['From'] = "me#gmail.com"
msg['To'] = "you#gmail.com"
# Send the message via our own SMTP server.
server = smtplib.SMTP_SSL('smtp.gmail.com', 465)
server.login("me#gmail.com", "password")
server.send_message(msg)
server.quit()

try this:
import smtplib
from email.mime.multipart import MIMEMultipart
msg = MIMEMultipart()
msg['From'] = 'sender_address'
msg['To'] = 'reciver_address'
msg['Subject'] = 'your_subject'
server = smtplib.SMTP('localhost')
server.sendmail('from_addr','to_addr',msg.as_string())

You should probably modify your code to something like this:
from smtplib import SMTP as smtp
from email.mime.text import MIMEText as text
s = smtp(server)
s.login(<mail-user>, <mail-pass>)
m = text(message)
m['Subject'] = 'Hello!'
m['From'] = <from-address>
m['To'] = <to-address>
s.sendmail(<from-address>, <to-address>, m.as_string())
Obviously, the <> variables need to be actual string values, or valid variables, I just filled them in as place holders. This works for me when sending messages with subjects.

See the note at the bottom of smtplib's documentation:
In general, you will want to use the email package’s features to construct an email message, which you can then convert to a string and send via sendmail(); see email: Examples.
Here's the link to the examples section of email's documentation, which indeed shows the creation of a message with a subject line. https://docs.python.org/3/library/email.examples.html
It appears that smtplib doesn't support subject addition directly and expects the msg to already be formatted with a subject, etc. That's where the email module comes in.

import smtplib
# creates SMTP session
List item
s = smtplib.SMTP('smtp.gmail.com', 587)
# start TLS for security
s.starttls()
# Authentication
s.login("login mail ID", "password")
# message to be sent
SUBJECT = "Subject"
TEXT = "Message body"
message = 'Subject: {}\n\n{}'.format(SUBJECT, TEXT)
# sending the mail
s.sendmail("from", "to", message)
# terminating the session
s.quit()

I think you have to include it in the message:
import smtplib
message = """From: From Person <from#fromdomain.com>
To: To Person <to#todomain.com>
MIME-Version: 1.0
Content-type: text/html
Subject: SMTP HTML e-mail test
This is an e-mail message to be sent in HTML format
<b>This is HTML message.</b>
<h1>This is headline.</h1>
"""
try:
smtpObj = smtplib.SMTP('localhost')
smtpObj.sendmail(sender, receivers, message)
print "Successfully sent email"
except SMTPException:
print "Error: unable to send email"
code from: http://www.tutorialspoint.com/python/python_sending_email.htm

In case of wrapping it in a function, this should work as a template.
def send_email(login, password, destinations, subject, message):
server = smtplib.SMTP_SSL("smtp.gmail.com", 465)
server.login(login, password)
message = 'Subject: {}\n\n{}'.format(subject, message)
for destination in destinations:
print("Sending email to:", destination)
server.sendmail(login, destinations, message)
server.quit()

try this out :
from = "myemail#site.com"
to= "someemail#site.com"
subject = "Hello there!"
body = "Have a good day."
message = "Subject:" + subject + "\n" + body
server.sendmail(from, , message)
server.quit()

How to send Gmail email with multiple CC:'s

I am looking for a quick example on how to send Gmail emails with multiple CC:'s. Could anyone suggest an example snippet?

I've rustled up a bit of code for you that shows how to connect to an SMTP server, construct an email (with a couple of addresses in the Cc field), and send it. Hopefully the liberal application of comments will make it easy to understand.
from smtplib import SMTP_SSL
from email.mime.text import MIMEText
## The SMTP server details
smtp_server = "smtp.gmail.com"
smtp_port = 587
smtp_username = "username"
smtp_password = "password"
## The email details
from_address = "address1#domain.com"
to_address = "address2#domain.com"
cc_addresses = ["address3#domain.com", "address4#domain.com"]
msg_subject = "This is the subject of the email"
msg_body = """
This is some text for the email body.
"""
## Now we make the email
msg = MIMEText(msg_body) # Create a Message object with the body text
# Now add the headers
msg['Subject'] = msg_subject
msg['From'] = from_address
msg['To'] = to_address
msg['Cc'] = ', '.join(cc_addresses) # Comma separate multiple addresses
## Now we can connect to the server and send the email
s = SMTP_SSL(smtp_server, smtp_port) # Set up the connection to the SMTP server
try:
s.set_debuglevel(True) # It's nice to see what's going on
s.ehlo() # identify ourselves, prompting server for supported features
# If we can encrypt this session, do it
if s.has_extn('STARTTLS'):
s.starttls()
s.ehlo() # re-identify ourselves over TLS connection
s.login(smtp_username, smtp_password) # Login
# Send the email. Note we have to give sendmail() the message as a string
# rather than a message object, so we need to do msg.as_string()
s.sendmail(from_address, to_address, msg.as_string())
finally:
s.quit() # Close the connection
Here's the code above on pastie.org for easier reading
Regarding the specific question of multiple Cc addresses, as you can see in the code above, you need to use a comma separated string of email addresses, rather than a list.
If you want names as well as addresses you might as well use the email.utils.formataddr() function to help get them into the right format:
>>> from email.utils import formataddr
>>> addresses = [("John Doe", "john#domain.com"), ("Jane Doe", "jane#domain.com")]
>>> ', '.join([formataddr(address) for address in addresses])
'John Doe <john#domain.com>, Jane Doe <jane#domain.com>'
Hope this helps, let me know if you have any problems.

If you can use a library, I highly suggest http://libgmail.sourceforge.net/, I have used briefly in the past, and it is very easy to use. You must enable IMAP/POP3 in your gmail account in order to use this.
As for a code snippet (I haven't had a chance to try this, I will edit this if I can):
import smtplib
from email.MIMEMultipart import MIMEMultipart
from email.MIMEBase import MIMEBase
from email.MIMEText import MIMEText
from email import Encoders
import os
#EDIT THE NEXT TWO LINES
gmail_user = "your_email#gmail.com"
gmail_pwd = "your_password"
def mail(to, subject, text, attach, cc):
msg = MIMEMultipart()
msg['From'] = gmail_user
msg['To'] = to
msg['Subject'] = subject
#THIS IS WHERE YOU PUT IN THE CC EMAILS
msg['Cc'] = cc
msg.attach(MIMEText(text))
part = MIMEBase('application', 'octet-stream')
part.set_payload(open(attach, 'rb').read())
Encoders.encode_base64(part)
part.add_header('Content-Disposition',
'attachment; filename="%s"' % os.path.basename(attach))
msg.attach(part)
mailServer = smtplib.SMTP("smtp.gmail.com", 587)
mailServer.ehlo()
mailServer.starttls()
mailServer.ehlo()
mailServer.login(gmail_user, gmail_pwd)
mailServer.sendmail(gmail_user, to, msg.as_string())
# Should be mailServer.quit(), but that crashes...
mailServer.close()
mail("some.person#some.address.com",
"Hello from python!",
"This is a email sent with python")
For the snippet I modified this

Sending mail from Python using SMTP

I'm using the following method to send mail from Python using SMTP. Is it the right method to use or are there gotchas I'm missing ?
from smtplib import SMTP
import datetime
debuglevel = 0
smtp = SMTP()
smtp.set_debuglevel(debuglevel)
smtp.connect('YOUR.MAIL.SERVER', 26)
smtp.login('USERNAME#DOMAIN', 'PASSWORD')
from_addr = "John Doe <john#doe.net>"
to_addr = "foo#bar.com"
subj = "hello"
date = datetime.datetime.now().strftime( "%d/%m/%Y %H:%M" )
message_text = "Hello\nThis is a mail from your server\n\nBye\n"
msg = "From: %s\nTo: %s\nSubject: %s\nDate: %s\n\n%s"
% ( from_addr, to_addr, subj, date, message_text )
smtp.sendmail(from_addr, to_addr, msg)
smtp.quit()

The script I use is quite similar; I post it here as an example of how to use the email.* modules to generate MIME messages; so this script can be easily modified to attach pictures, etc.
I rely on my ISP to add the date time header.
My ISP requires me to use a secure smtp connection to send mail, I rely on the smtplib module (downloadable at http://www1.cs.columbia.edu/~db2501/ssmtplib.py)
As in your script, the username and password, (given dummy values below), used to authenticate on the SMTP server, are in plain text in the source. This is a security weakness; but the best alternative depends on how careful you need (want?) to be about protecting these.
=======================================
#! /usr/local/bin/python
SMTPserver = 'smtp.att.yahoo.com'
sender = 'me#my_email_domain.net'
destination = ['recipient#her_email_domain.com']
USERNAME = "USER_NAME_FOR_INTERNET_SERVICE_PROVIDER"
PASSWORD = "PASSWORD_INTERNET_SERVICE_PROVIDER"
# typical values for text_subtype are plain, html, xml
text_subtype = 'plain'
content="""\
Test message
"""
subject="Sent from Python"
import sys
import os
import re
from smtplib import SMTP_SSL as SMTP # this invokes the secure SMTP protocol (port 465, uses SSL)
# from smtplib import SMTP # use this for standard SMTP protocol (port 25, no encryption)
# old version
# from email.MIMEText import MIMEText
from email.mime.text import MIMEText
try:
msg = MIMEText(content, text_subtype)
msg['Subject']= subject
msg['From'] = sender # some SMTP servers will do this automatically, not all
conn = SMTP(SMTPserver)
conn.set_debuglevel(False)
conn.login(USERNAME, PASSWORD)
try:
conn.sendmail(sender, destination, msg.as_string())
finally:
conn.quit()
except:
sys.exit( "mail failed; %s" % "CUSTOM_ERROR" ) # give an error message

The method I commonly use...not much different but a little bit
import smtplib
from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText
msg = MIMEMultipart()
msg['From'] = 'me#gmail.com'
msg['To'] = 'you#gmail.com'
msg['Subject'] = 'simple email in python'
message = 'here is the email'
msg.attach(MIMEText(message))
mailserver = smtplib.SMTP('smtp.gmail.com',587)
# identify ourselves to smtp gmail client
mailserver.ehlo()
# secure our email with tls encryption
mailserver.starttls()
# re-identify ourselves as an encrypted connection
mailserver.ehlo()
mailserver.login('me#gmail.com', 'mypassword')
mailserver.sendmail('me#gmail.com','you#gmail.com',msg.as_string())
mailserver.quit()
That's it

Also if you want to do smtp auth with TLS as opposed to SSL then you just have to change the port (use 587) and do smtp.starttls(). This worked for me:
...
smtp.connect('YOUR.MAIL.SERVER', 587)
smtp.ehlo()
smtp.starttls()
smtp.ehlo()
smtp.login('USERNAME#DOMAIN', 'PASSWORD')
...

Make sure you don't have any firewalls blocking SMTP. The first time I tried to send an email, it was blocked both by Windows Firewall and McAfee - took forever to find them both.

What about this?
import smtplib
SERVER = "localhost"
FROM = "sender#example.com"
TO = ["user#example.com"] # must be a list
SUBJECT = "Hello!"
TEXT = "This message was sent with Python's smtplib."
# Prepare actual message
message = """\
From: %s
To: %s
Subject: %s
%s
""" % (FROM, ", ".join(TO), SUBJECT, TEXT)
# Send the mail
server = smtplib.SMTP(SERVER)
server.sendmail(FROM, TO, message)
server.quit()

The main gotcha I see is that you're not handling any errors: .login() and .sendmail() both have documented exceptions that they can throw, and it seems like .connect() must have some way to indicate that it was unable to connect - probably an exception thrown by the underlying socket code.

following code is working fine for me:
import smtplib
to = 'mkyong2002#yahoo.com'
gmail_user = 'mkyong2002#gmail.com'
gmail_pwd = 'yourpassword'
smtpserver = smtplib.SMTP("smtp.gmail.com",587)
smtpserver.ehlo()
smtpserver.starttls()
smtpserver.ehlo()
smtpserver.login(gmail_user, gmail_pwd)
header = 'To:' + to + '\n' + 'From: ' + gmail_user + '\n' + 'Subject:testing \n'
print header
msg = header + '\n this is test msg from mkyong.com \n\n'
smtpserver.sendmail(gmail_user, to, msg)
print 'done!'
smtpserver.quit()
Ref: http://www.mkyong.com/python/how-do-send-email-in-python-via-smtplib/

The example code which i did for send mail using SMTP.
import smtplib, ssl
smtp_server = "smtp.gmail.com"
port = 587 # For starttls
sender_email = "sender#email"
receiver_email = "receiver#email"
password = "<your password here>"
message = """ Subject: Hi there
This message is sent from Python."""
# Create a secure SSL context
context = ssl.create_default_context()
# Try to log in to server and send email
server = smtplib.SMTP(smtp_server,port)
try:
server.ehlo() # Can be omitted
server.starttls(context=context) # Secure the connection
server.ehlo() # Can be omitted
server.login(sender_email, password)
server.sendmail(sender_email, receiver_email, message)
except Exception as e:
# Print any error messages to stdout
print(e)
finally:
server.quit()

You should make sure you format the date in the correct format - RFC2822.

See all those lenghty answers? Please allow me to self promote by doing it all in a couple of lines.
Import and Connect:
import yagmail
yag = yagmail.SMTP('john#doe.net', host = 'YOUR.MAIL.SERVER', port = 26)
Then it is just a one-liner:
yag.send('foo#bar.com', 'hello', 'Hello\nThis is a mail from your server\n\nBye\n')
It will actually close when it goes out of scope (or can be closed manually). Furthermore, it will allow you to register your username in your keyring such that you do not have to write out your password in your script (it really bothered me prior to writing yagmail!)
For the package/installation, tips and tricks please look at git or pip, available for both Python 2 and 3.

you can do like that
import smtplib
from email.mime.text import MIMEText
from email.header import Header
server = smtplib.SMTP('mail.servername.com', 25)
server.ehlo()
server.starttls()
server.login('username', 'password')
from = 'me#servername.com'
to = 'mygfriend#servername.com'
body = 'That A Message For My Girl Friend For tell Him If We will go to eat Something This Nigth'
subject = 'Invite to A Diner'
msg = MIMEText(body,'plain','utf-8')
msg['Subject'] = Header(subject, 'utf-8')
msg['From'] = Header(from, 'utf-8')
msg['To'] = Header(to, 'utf-8')
message = msg.as_string()
server.sendmail(from, to, message)

Based on this example I made following function:
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
def send_email(host, port, user, pwd, recipients, subject, body, html=None, from_=None):

except Exception, ex:
return ex
return None
if you pass only body then plain text mail will be sent, but if you pass html argument along with body argument, html email will be sent (with fallback to text content for email clients that don't support html/mime types).
Example usage:
ex = send_email(
host = 'smtp.gmail.com'
#, port = 465 # OK
, port = 587 #OK

, body = "Test from python - body"
)
if ex:
print("Mail sending failed: %s" % ex)
else:
print("OK - mail sent"
Btw. If you want to use gmail as testing or production SMTP server,
enable temp or permanent access to less secured apps:
login to google mail/account
go to: https://myaccount.google.com/lesssecureapps
enable
send email using this function or similar
(recommended) go to: https://myaccount.google.com/lesssecureapps
(recommended) disable

smtp_server.starttls()
smtp_server.ehlo()
smtp_server.login("USERNAME#DOMAIN", password)
smtp_server.send_message(message)
except Exception as e:
print("Error: ", str(e))
finally:
if smtp_server is not None:
smtp_server.quit()
If you want to use Port 465 you have to create an SMTP_SSL object.

Here's a working example for Python 3.x
#!/usr/bin/env python3
from email.message import EmailMessage
from getpass import getpass
from smtplib import SMTP_SSL
from sys import exit
smtp_server = 'smtp.gmail.com'
username = 'your_email_address#gmail.com'
password = getpass('Enter Gmail password: ')
sender = 'your_email_address#gmail.com'
destination = 'recipient_email_address#gmail.com'
subject = 'Sent from Python 3.x'
content = 'Hello! This was sent to you via Python 3.x!'
# Create a text/plain message
msg = EmailMessage()
msg.set_content(content)
msg['Subject'] = subject
msg['From'] = sender
msg['To'] = destination
try:
s = SMTP_SSL(smtp_server)
s.login(username, password)
try:
s.send_message(msg)
finally:
s.quit()
except Exception as E:
exit('Mail failed: {}'.format(str(E)))

What about Red Mail?
Install it:
pip install redmail
Then just:
from redmail import EmailSender
# Configure the sender
email = EmailSender(
host="YOUR.MAIL.SERVER",
port=26,
username='me#example.com',
password='<PASSWORD>'
)
# Send an email:
email.send(
subject="An example email",
sender="me#example.com",
receivers=['you#example.com'],
text="Hello!",
html="<h1>Hello!</h1>"
)
It has quite a lot of features:
Email attachments from various sources
Embedding images and plots to the HTML body
Templating emails with Jinja
Preconfigured Gmail and Outlook
Logging handler
Flask extension
