Sending emails with smtp python, problem with def block

I'm new to python, I'm working with python 3. I need to send an email with generated message. Everything is ok with message (I can print it) but somehow in that configuration, with that def-blocks emails aren't sent. What am I doing wrong? I don't get any error notifications.
import random
import string
import smtplib
port = 2525
smtp_server = "smtp.mailtrap.io"
login = "my mailtrap login"
password = "my mailtrap pass"
sender = "from#smtp.mailtrap.io"
receiver = "to#smtp.mailtrap.io"
def randomString(stringLength=10):
letters = string.ascii_lowercase
return ''.join(random.choice(letters) for i in range(stringLength))
def randomMessage():
random_string1 = randomString()
random_string2 = randomString()
message = f"""\
Subject: {random_string1}
To: {receiver}
From: {sender}
{random_string2}"""
return message
def main():
with smtplib.SMTP(smtp_server, port) as server:
server.login(login, password)
message = randomMessage()
#print(message)
server.sendmail(sender, receiver, message)
if __name__ == '__main__':
main()

Problem was in message type. I changed it to MIMEText and it works now.
import random
import string
import smtplib
from email.mime.text import MIMEText
port = 2525
smtp_server = "smtp.mailtrap.io"

password = "my mailtrap pass"
sender = "from#smtp.mailtrap.io"
receiver = "to#smtp.mailtrap.io"
def randomString(stringLength=10):
lettersDigits = string.ascii_lowercase + "0123456789"
return ''.join(random.choice(lettersDigits) for i in range(stringLength))
def makeMessage(subject, content):
message = MIMEText(content)
message["Subject"] = subject
message["From"] = sender
message["To"] = receiver
return message
def randomMessage():
return makeMessage(randomString(), randomString())
def sendMessage(message):
with smtplib.SMTP(smtp_server, port) as server:
server.login(login, password)
server.sendmail(sender, receiver, message.as_string())

How can I send email to multi addresses by smtplib?

I use bellow code I can send email to one account, but how can I send to multi account?
import smtplib
from email.mime.text import MIMEText
_user = "67676767#qq.com" #
_pwd = "orjxywulscbxsdwbaii" #
_to = linux213#126.com" #
msg = MIMEText("content") #
msg["Subject"] = "邮件主题测试" #
msg["From"] = _user
msg["To"] = _to
try:
s = smtplib.SMTP_SSL("smtp.qq.com", 465)
s.login(_user, _pwd)
s.sendmail(_user, _to, msg.as_string())
s.quit()
print ("Success!")
except smtplib.SMTPException as e:
print ("Falied,%s" % e)

Try this:
import smtplib
from email.mime.text import MIMEText
s = smtplib.SMTP('smtp.qq.com')
s.set_debuglevel(1)
msg = MIMEText("""body""")
sender = 'me#example.com'
recipients = ['k.ankur#abc.com', 'a.smith#abc.co.in']
msg['Subject'] = "subject line"
msg['From'] = sender
msg['To'] = ", ".join(recipients)
s.sendmail(sender, recipients, msg.as_string())

BCC not hidden on gmail using python smtplib

I am working on a python script to send email to my customer with a survey. I will send only one email with all my customers's emails in the BCC field so that I do not need to loop through all the emails. Everything works fine when I tested sending emails to my company's coleagues and also when I sent to my personal email, but whenever I send to a gmail account, the BCC field appears to not be hidden and show all the emails. I found this post Email Bcc recipients not hidden using Python smtplib and tried that solution as well, but as I am using a html body email, the emails were shown inside the body. Can anyone help me on this one?
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.image import MIMEImage
def send_survey_mail():
template_path = 'template.html'
background_path = 'image.png'
button_path = 'image2.png'
try:
body = open(template_path, 'r')
msg = MIMEMultipart()
msg['Subject'] = 'Customer Survey'
msg['To'] = ', '.join(['myemail#domain.com.br', 'myemail2#domain.com'])
msg['From'] = 'mycompany#mycompany.com.br'
msg['Bcc'] = 'customer#domain.com'
text = MIMEText(body.read(), 'html')
msg.attach(text)
fp = open(background_path, 'rb')
img = MIMEImage(fp.read())
fp.close()
fp2 = open(button_path, 'rb')
img2 = MIMEImage(fp2.read())
fp2.close()
img.add_header('Content-ID', '<image1>')
msg.attach(img)
img2.add_header('Content-ID', '<image2>')
msg.attach(img2)
s = smtplib.SMTP('smtpserver')
s.sendmail('mycompany#mycompany.com.br',
['myemail#domain.com.br', 'myemail2#domain.com', 'customer#domain.com'],
msg.as_string())
s.quit()
except Exception as ex:
raise ex
send_survey_mail()
I removed the following line from the code and tried again. Now the email is not sent to my customer's Gmail email.
msg['Bcc'] = 'customer#gmail.com'

Just do not mention bcc mails in msg['To'] or msg['Cc']. Do it only in server.sendmail()
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.base import MIMEBase
from email import encoders
from_addr = "your#mail.com"
to_addr = ["to#mail.com", "to2#mail.com"]
msg = MIMEMultipart()
msg['From'] = from_addr
msg['To'] = to_addr
msg['Subject'] = "SUBJECT"
body = "BODY"
msg.attach(MIMEText(body, 'plain'))
filename = "FILE.pdf"
attachment = open('/home/FILE.pdf', "rb")
part = MIMEBase('application', 'octet-stream')
part.set_payload((attachment).read())
encoders.encode_base64(part)
part.add_header('Content-Disposition', "attachment; filename= %s" % filename)
msg.attach(part)
server = smtplib.SMTP('.....', 587)
server.starttls()
server.login(from_addr, 'yourpass')
text = msg.as_string()
server.sendmail(from_addr, to_addr + [bcc#mail.com], text)
server.quit()

Did you try not to define the msg['BCC'] field? Setting this field forces it to be included. It is sufficient that the BCC email address is in the sendmail command's destination address list. Take a look at this question.

MAIL_FROM = default#server.com
MAIL_DL = default#server.com
def send(to, cc, bcc, subject, text, html):
message = MIMEMultipart("alternative")
message["Subject"] = subject
message["From"] = MAIL_FROM
message["To"] = to
message["Cc"] = cc + "," + MAIL_DL
if html is not None:
body = MIMEText(html, "html")
else:
body = MIMEText(text)
message.attach(body)
server = smtplib.SMTP(MAIL_SERVER)
server.set_debuglevel(1)
server.sendmail(MAIL_DL, to.split(",") + bcc.split(","), message.as_string())
server.quit()
return {
"to": to,
"cc": cc,
"bcc": bcc,
"subject": subject,
"text": text,
"html": html,
}

send mail using python

Problem: when i send mail to user then from user name not seen in to user inbox only show email-id but i need user name of sender
from: demo#gmail.com username: Demo
To: demotest#gmail.com
CODE
import smtplib
fromaddr = From
toaddrs = To
msg = 'Why,Oh why!'
username = From
password = *******
server = smtplib.SMTP('smtp.gmail.com:587')
server.ehlo()
server.starttls()
server.login(username, password)
server.sendmail(fromaddr, toaddrs, msg)
server.quit()

smtplib does not include automatically any header, and you need to include a From: header, so you have to put one by yourself doing something like:
# Add the From: and To: headers at the start!
msg = ("From: %s\r\nTo: %s\r\n\r\n"
% (fromaddr, ", ".join(toaddrs)))
As you can se in the DOCS.

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
fromaddr = 'demo#gmail.com'
toaddrs = 'demotest#gmail.com'
msg = MIMEMultipart('alternative')
msg['Subject'] = "Link"
msg['From'] = "good morning" #like name
msg['To'] = "GGGGGG"
body = MIMEText("example email body")
msg.attach(body)
username = 'demo#gmail.com'
password = ''
server = smtplib.SMTP_SSL('smtp.googlemail.com', 465)
server.login(username, password)
server.sendmail(fromaddr, toaddrs, msg.as_string())
server.quit()

You just need to create the message correctly. I think the most convenient way to do it is using a special object for message. I placed a class which perhaps may help you to send messages in your project.
import os
import smtplib
from email.mime.text import MIMEText
from email.mime.image import MIMEImage
from email.mime.multipart import MIMEMultipart
class EmailSender(object):
def __init__(self, subject, to, config):
self.__subject = subject
self.__to = tuple(to) if hasattr(to, '__iter__') else (to,)
self.__from = config['user']
self.__password = config['password']
self.__server = config['server']
self.__port = config['port']
self.__message = MIMEMultipart()
self.__message['Subject'] = self.__subject
self.__message['From'] = self.__from
self.__message['To'] = ', '.join(self.__to)
def add_text(self, text):
self.__message.attach(
MIMEText(text)
)
def add_image(self, img_path, name=None):
if name is None:
name = os.path.basename(img_path)
with open(img_path, 'rb') as f:
img_data = f.read()
image = MIMEImage(img_data, name=name)
self.__message.attach(image)
def send(self):
server = smtplib.SMTP_SSL(self.__server, self.__port)
server.login(self.__from, self.__password)
server.sendmail(self.__from, self.__to, self.__message.as_string())
server.close()
sender = EmailSender("My letter", "my_target#email", {
'user': "from#email",
'password': "123456",
'server': "mail.google.com"
'port': 465
})
sender.add_text("Why,Oh why!")
sender.send()

Or go the easy way, by install yagmail and
Given:
To = 'someone#gmail.com'
From = 'me#gmail.com'
pwd = '******'
alias = 'someone'
Run:
import yagmail
yag = yagmail.SMTP(From, pwd)
yag.send({To: alias}, 'subject', 'Why,Oh why!')
Install might be done by pip install yagmail

Python SMTP/MIME Message body

I've been working on this for 2 days now and managed to get this script with a pcapng file attached to send but I cannot seem to make the message body appear in the email.
import smtplib

import ConfigParser
#from email.MIMEapplication import MIMEApplication
#from email.MIMEmultipart import MIMEMultipart
#from email.MIMEtext import MIMEText
#from email.utils import COMMASPACE, formatdate
Config = ConfigParser.ConfigParser()
Config.read('mailsend.ini')
filename = "test.pcapng"
fo = open(filename, "rb")
filecontent = fo.read()
encoded_content = base64.b64encode(filecontent) # base 64
sender = 'notareal#email.com' # raw_input("Sender: ")
receiver = 'someother#fakeemail.com' # raw_input("Recipient: ")
marker = raw_input("Please input a unique set of numbers that will not be found elsewhere in the message, ie- roll face: ")
body ="""
This is a test email to send an attachment.
"""
# Define the main headers
header = """ From: From Person <notareal#email.com>
To: To Person <someother#fakeemail.com>
Subject: Sending Attachment

""" % (marker, marker)
# Define message action
message_action = """Content-Type: text/plain

# Define the attachment section
message_attachment = """Content-Type: multipart/mixed; name=\"%s\"
Content-Transfer-Encoding:base64

""" % (filename, filename, encoded_content, marker)
message = header + message_action + message_attachment
try:
smtpObj = smtplib.SMTP('smtp.gmail.com')
smtpObj.sendmail(sender, receiver, message)
print "Successfully sent email!"
except Exception:
print "Error: unable to send email"
My goal is to ultimately have this script send an email after reading the parameters from a config file and attach a pcapng file along with some other text data describing the wireshark event. The email is not showing the body of the message when sent. The pcapng file is just a test file full of fake ips and subnets for now. Where have I gone wrong with the message body?
def mail_man():
if ms == 'Y' or ms == 'y' and ms_maxattach <= int(smtp.esmtp_features['size']):
fromaddr = [ms_from]
toaddr = [ms_sendto]
cc = [ms_cc]
bcc = [ms_bcc]
msg = MIMEMultipart()
body = "\nYou're captured event is attached. \nThis is an automated email generated by Dumpcap.py"
msg.attach("From: %s\r\n" % fromaddr
+ "To: %s\r\n" % toaddr
+ "CC: %s\r\n" % ",".join(cc)
+ "Subject: %s\r\n" % ms_subject
+ "X-Priority = %s\r\n" % ms_importance
+ "\r\n"
+ "%s\r\n" % body
+ "%s\r\n" % ms_pm)
toaddrs = [toaddr] + cc + bcc
msg.attach(MIMEText(body, 'plain'))
filename = "dcdflts.cong"
attachment = open(filename, "rb")
if ms_attach == 'y' or ms_attach == "Y":
part = MIMEBase('application', 'octet-stream')
part.set_payload(attachment.read())
encoders.encode_base64(part)
part.add_header('Content-Disposition', "attachment; filename= %s" % filename)
msg.attach(part)
server = smtplib.SMTP(ms_smtp_server[ms_smtp_port])
server.starttls()
server.login(fromaddr, "YOURPASSWORD")
text = msg.as_string()
server.sendmail(fromaddr, toaddrs, text)
server.quit()
This is my second attempt, all "ms_..." variables are global through a larger program.

You shouldn't be reinventing the wheel. Use the mime modules Python has included in the standard library instead of trying to create the headers on your own. I haven't been able to test it out but check if this works:
import smtplib
import base64
import ConfigParser
from email.mime.application import MIMEApplication
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
filename = "test.pcapng"
with open(filename, 'rb') as fo:
filecontent = fo.read()
encoded_content = base64.b64encode(filecontent)
sender = 'notareal#email.com' # raw_input("Sender: ")
receiver = 'someother#fakeemail.com' # raw_input("Recipient: ")
marker = raw_input("Please input a unique set of numbers that will not be found elsewhere in the message, ie- roll face: ")
body ="""
This is a test email to send an attachment.
"""
message = MIMEMultipart(
From=sender,
To=receiver,
Subject='Sending Attachment')
message.attach(MIMEText(body)) # body of the email
message.attach(MIMEApplication(
encoded_content,
Content_Disposition='attachment; filename="{0}"'.format(filename)) # b64 encoded file
)
try:
smtpObj = smtplib.SMTP('smtp.gmail.com')
smtpObj.sendmail(sender, receiver, message)
print "Successfully sent email!"
except Exception:
print "Error: unable to send email"
I've left off a few parts (like the ConfigParser variables) and demonstrated only the email related portions.
