Hi,
I have a very simple piece of code (just for testing):
import smtplib
import time
server = 'smtp.myprovider.com'
recipients = ['[email protected]']
sender = '[email protected]'
message = 'Subject: [PGS]: Results\n\nBlaBlaBla'
session = smtplib.SMTP(server)
session.sendmail(sender,recipients,message);
This works but the problem is that e-mail clients don't display a sender. I want to be able to add a sender name to the e-mail. Suggestions?
smtplib doesn't automatically include a From: header, so you have to put one in yourself:
message = 'From: [email protected]\nSubject: [PGS]: Results\n\nBlaBlaBla'
(In fact, smtplib doesn't include any headers automatically, but just sends the text that you give it as a raw message)
You can utilize the email.message.Message class, and use it to generate mime headers, including from:, to: and subject. Send the as_string() result via SMTP.
>>> from email import message
>>> m1=message.Message()
>>> m1.add_header('from','[email protected]')
>>> m1.add_header('to','[email protected]')
>>> m1.add_header('subject','test')
>>> m1.set_payload('test\n')
>>> m1.as_string()
'from: [email protected]\nto: [email protected]\nsubject: test\n\ntest\n'
>>>
The "sender" you're specifying in this case is the envelope sender that is passed onto the SMTP server.
What your MUA (Mail User Agent - i.e. outlook/Thunderbird etc.) shows you is the "From:" header.
Normally, if I'm using smtplib, I'd compile the headers separately:
headers = "From %s\nTo: %s\n\n" % (email_from, email_to)
The format of the From header is by convention normally "Name" <user@domain>
You should be including a "Message-Id" header and a "Reply-To" header as well in all communications. Especially since spam filters may pick up on the lack of these as a great probability that the mail is spam.
If you've got your mail body in the variable body, just compile the overall message with:
message = headers + body
Note the double newline at the end of the headers. It's also worth noting that SMTP servers should separate headers with newlines only (i.e. LF - linfeed). However, I have seen a Windows SMTP server or two that uses \r\n (i.e. CRLF). If you're on Windows, YMMV.
