I need to send a message when my program is done running, but I also want to include variables such as how long the program took to run in the text.
Here is my code for the texting:
import smtplib
carriers = {
'att': '#mms.att.net',
'tmobile': ' #tmomail.net',
'verizon': '#vtext.com',
'sprint': '#page.nextel.com'
}
def send(message):
# Replace the number with your own, or consider using an argument\dict for multiple people.
to_number = 'xxxxxxxxxx{}'.format(carriers['verizon'])
auth = ('xxxxx', 'xxxx')
# Establish a secure session with gmail's outgoing SMTP server using your gmail account
server = smtplib.SMTP("smtp.gmail.com", 587)
server.starttls()
server.login(auth[0], auth[1])
# Send text message through SMS gateway of destination number
server.sendmail(auth[0], to_number, message)
Obviously, I replaced my info with the xxx.
Now, to send my text I'm calling the function using:
found = 'The program is done!'
timetook = "Time took: %s (HOUR:MIN:SEC)" % timedelta(seconds=round(elapsed_time_secs))
send(found)
send(timetook)
It just sends blank texts for the timetook, but the program is done message works fine. How do I send the timetook?
The problem is that you aren't following the rules for SMTP. Below is the equivalent solution I wrote for my own use many years ago.

# TO_ADDR = PHONE_NUMBER + '#tmomail.net'
# Verizon SMS email gateway
TO_ADDR = PHONE_NUMBER + '#vtext.com'
# Allow only three SMS messages per minute and five per hour.
short_term_rate_limiter = rate_limiting.SimpleRateLimiter(3, 60)
long_term_rate_limiter = rate_limiting.SimpleRateLimiter(5, 60 * 60)
def SendSms(msg, why=''):
"""Send a SMS message."""
short_term_rate_exceeded = short_term_rate_limiter()
long_term_rate_exceeded = long_term_rate_limiter()
if short_term_rate_exceeded or long_term_rate_exceeded:

return
smtp_conn = smtplib.SMTP(SMTP_GATEWAY)
hdrs = 'From: {}\r\nTo: {}\r\n\r\n'.format(FROM_ADDR, TO_ADDR)
if why:
hdrs += 'Subject: {}\r\n'.format(why[:20])
hdrs += "\r\n\r\n"
max_msg_len = 140 - 3 - min(20, len(why))
msg = hdrs + msg[:max_msg_len]
# Make sure the message has only ASCII characters.
msg = msg.encode('ascii', errors='replace').decode('ascii')
smtp_conn.sendmail(FROM_ADDR, [TO_ADDR], msg)
smtp_conn.quit()

I am using the code below to try to send an MMS message with python-messaging https://github.com/pmarti/python-messaging/blob/master/doc/tutorial/mms.rst Although the connection seems to go smoothly I get the following response from the mmsc:

Does, anyone have an idea on what the problem might be and how I can fix it? Here is my code:
from messaging.mms.message import MMSMessage, MMSMessagePage
mms = MMSMessage()
mms.headers['To'] = '+212XXXXXXX/TYPE=PLMN'
mms.headers['Message-Type'] = 'm-send-req'
mms.headers['Subject'] = 'Test python-messaging.mms'
slide1 = MMSMessagePage()
slide1.add_image('/home/richard/screensaver/TolleConscQte.jpg')
slide1.add_text('This first slide, is a step towards enlightenment.')
slide2 = MMSMessagePage()
slide2.set_duration(4500)

I am using this regular expression for SIP (Session Initiation Protocol) URIs to extract the different internal variables.
_syntax = re.compile('^(?P<scheme>[a-zA-Z][a-zA-Z0-9\+\-\.]*):' # scheme
+ '(?:(?:(?P<user>[a-zA-Z0-9\-\_\.\!\~\*\'\(\)&=\+\$,;\?\/\%]+)' # user
+ '(?::(?P<password>[^:#;\?]+))?)#)?' # password
+ '(?:(?:(?P<host>[^;\?:]*)(?::(?P<port>[\d]+))?))' # host, port
+ '(?:;(?P<params>[^\?]*))?' # parameters
+ '(?:\?(?P<headers>.*))?$') # headers
m = URI._syntax.match(value)
if m:
self.scheme, self.user, self.password, self.host, self.port, params, headers = m.groups()
and i want to extract specific header like the header via,branch,contact,callID or Cseq.
The general form of a sip message is:
OPTIONS sip:172.16.18.35:5060 SIP/2.0
Content-Length: 0
Via: SIP/2.0/UDP 172.16.18.90:5060
From: "fake" <sip:fake#172.16.18.90>
Supported: replaces, timer
User-Agent: SIPPing
To: <sip:172.16.18.35:5060>
Contact: <sip:fake#172.16.18.90:5060>
CSeq: 1 OPTIONS
Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH
Call-ID: fake-id#172.16.18.90
Date: Thu, 25 Apr 2013 003024 +0000
Max-Forwards: 70
I would suggest taking advantage of the intentional similarities between SIP header format and RFC822.
from email.parser import Parser
msg = Parser().parsestr(m.group('headers'))
...thereafter:
>>> msg.keys()
['Content-Length', 'Via', 'From', 'Supported', 'User-Agent', 'To', 'Contact', 'CSeq', 'Allow', 'Call-ID', 'Date', 'Max-Forwards']
>>> msg['To']
'<sip:172.16.18.35:5060>'
>>> msg['Date']
'Thu, 25 Apr 2013 003024 +0000'
...etc. See the documentation for the Python standard-library email module for more details.
I'm hoping this is just something simple. I'm trying to determine whether or not an email is already encrypted.
# Read e-mail from stdin
raw = sys.stdin.read()
raw_message = email.message_from_string( raw )
I took the example from http://docs.python.org/2/howto/regex.html on doing a simple test for match.
p = re.compile('-----BEGIN\sPGP\sMESSAGE-----')
m = p.match(raw)
if m:
log = open(cfg['logging']['file'], 'a')
log.write("THIS IS ENCRYPTED")
log.close()
else:
log = open(cfg['logging']['file'], 'a')
log.write("NOT ENCRYPTED:")
log.close()
The email is read. The log file is written to but it always comes back no match. I've written raw to a logfile and that string is present.
Not sure where to go next.
UPDATE:
Here is the output from a raw ( a simple test message )

re.match will only find a match at the beginning of the string, as noted here. You want to use re.search

Although, as noted, regex is likely overkill for this problem as the matching text is static.
Regular expressions are used when you want a "fuzzy" match - that is, you aren't sure if the string you are looking for will be identical every time.
In this case, the string you are looking for appears to be exactly -----BEGIN PGP MESSAGE----. In this case, the string.find function will be simpler to use and faster to boot.
>>> a = "This is a PGP encrypted email. -----BEGIN PGP MESSAGE----- !##$%^..."
>>> b = "This is not encrypted. My hovercraft is full of eels." #example strings
>>> a.find("-----BEGIN PGP MESSAGE-----")
30 # Return value '30' means that the search string was found at index 30 of source string
>>> b.find("-----BEGIN PGP MESSAGE-----")
-1 # -1 means 'not found in the source string'

I wrote a python script to fetch all of my gmail. I have hundreds of thousands of old emails, of which about 10,000 were unread.
After successfully fetching all of my email, I find that gmail has marked all the fetched emails as "read". This is disastrous for me since I need to check all unread emails only.
How can I recover the information about which emails were unread? I dumped each mail object into files, the core of my code is shown below:
m = imaplib.IMAP4_SSL("imap.gmail.com")
m.login(user,pwd)
m.select("[Gmail]/All Mail")
resp, items = m.uid('search', None, 'ALL')
uids = items[0].split()
for uid in uids:
resp, data = m.uid('fetch', uid, "(RFC822)")
email_body = data[0][1]
mail = email.message_from_string(email_body)
dumbobj(uid, mail)
I am hoping there is either an option to undo this in gmail, or a member inside the stored mail objects reflecting the seen-state information.
For anyone looking to prevent this headache, consider this answer here. This does not work for me, however, since the damage has already been done.
Edit:
I have written the following function to recursively "grep" all strings in an object, and applied it to a dumped email object using the following keywords:
regex = "(?i)((marked)|(seen)|(unread)|(read)|(flag)|(delivered)|(status)|(sate))"
So far, no results (only an unrelated "Delivered-To"). Which other keywords could I try?
def grep_object (obj, regex , cycle = set(), matched = set()):
import re
if id(obj) in cycle:
return
cycle.update([id(obj)])
if isinstance(obj, basestring):
if re.search(regex, obj):
matched.update([obj])
def grep_dict (adict ):
try:
[ [ grep_object(a, regex, cycle, matched ) for a in ab ] for ab in adict.iteritems() ]
except:pass
grep_dict(obj)
try:grep_dict(obj.__dict__)
except:pass
try:
[ grep_object(elm, regex, cycle, matched ) for elm in obj ]
except: pass
return matched
grep_object(mail_object, regex)
I'm having a similar problem (not with gmail), and the biggest problem for me was to make a reproducible test case; and I finally managed to produce one (see below).
In terms of the Seen flag, I now gather it goes like this:
If a message is new/unseen, IMAP fetch for \Seen flag will return empty (i.e. it will not be present, as related to the email message).
If you do IMAP select on a mailbox (INBOX), you get a "flag" UNSEEN which contains a list of ids (or uids) of emails in that folder that are new (do not have the \Seen flag)
In my test case, if you fetch say headers for a message with BODY.PEEK, then \Seen on a message is not set; if you fetch them with BODY, then \Seen is set
In my test case, also fetching (RFC822) doesn't set \Seen (unlike your case with Gmail)
In the test case, I try to do pprint.pprint(inspect.getmembers(mail)) (in lieu of your dumpobj(uid, mail)) - but only after I'm certain \Seen has been set. The output I get is posted in mail_object_inspect.txt - and as far as I can see, there is no mention of 'new/read/seen' etc. in none of the readable fields; furthermore mail.as_string() prints:
'From: jesse#example.com\nTo: user#example.com\nSubject: This is a test message!\n\nHello. I am executive assistant to the director of\nBear Stearns, a failed investment Bank. I have\naccess to USD6,000,000. ...\n'
Even worse, there is no mention of "fields" anywhere in the imaplib code (below filenames are printed if they do not contain case-insensitive "field" anywhere):
$ grep -L -i field /usr/lib/python{2.7,3.2}/imaplib.py
/usr/lib/python2.7/imaplib.py
/usr/lib/python3.2/imaplib.py
... so I guess that information was not saved with your dumps.
Here is a bit on reconstructing the test case. The hardest was to find a small IMAP server, that can be quickly ran with some arbitrary users and emails, but without having to install a ton of stuff on your system. Finally I found one: trivial-server.pl, the example file of Perl's Net::IMAP::Server; tested on Ubuntu 11.04.
The test case is pasted in this gist, with two files (with many comments) that I'll try to post abridged:
trivial-serverB.pl - Perl (v5.10.1) Net::IMAP::Server server (has a terminal output paste at end of file with a telnet client session)
testimap.py - Python 2.7/3.2 imaplib
client (has a terminal output paste at end of file, of itself operating with the server)
trivial-serverB.pl
First, make sure you have Net::IMAP::Server - note, it has many dependencies, so the below command may take a while to install:
sudo perl -MCPAN -e 'install Net::IMAP::Server'
Then, in the directory where you got trivial-serverB.pl, create a subdirectory with SSL certificates:
mkdir certs
openssl req \
-x509 -nodes -days 365 \
-subj '/C=US/ST=Oregon/L=Portland/CN=localhost' \
-newkey rsa:1024 -keyout certs/server-key.pem -out certs/server-cert.pem
Finally run the server with administrative properties:
sudo perl trivial-serverB.pl
Note that the trivial-serverB.pl has a hack which will let a client to connect without SSL. Here is trivial-serverB.pl:

With the server above running in one terminal, in another terminal you can just do:
python testimap.py
The code will simply read fields and content from the one (and only) message the server above presents, and will eventually restore (remove) the \Seen field.
