smtp question

[Philippe C. Martin]

Hi,

I am testing the smtp module and have the following question:

in the code below (taken from net sample) prior to adding the "Subject:"
field, the email client found the "From" and the "To". Without the
"Subject:" field on I get this:

Email client = Evolution: the "From" field is blank
Email client = KMail: the "To" field is blank

Any clue ?

Thanks and regards,

Philippe

Philippe,

Looks like the problem lies where you have added the Subject header.
You have terminated it with a \n\n and then your From and To headers.
You may want to rewrite it as:

server.sendmail(fromaddr, toaddrs, 'Subject:from python\r\n'+msg)

Why dont you consider using the email module -
http://python.org/doc/2.4/lib/module-email.html ? It is elegant and
easy to use.

Thank you,

You've got \n\n after the Subject line, not \r\n. That is being treated
as two newlines, thus ending the headers.

It' very easy to create email messages with the email module.

>>> from email.Message import Message
>>> fromaddr = '(e-mail address removed)'
>>> to = '(e-mail address removed)'
>>> msg = Message()
>>> msg['Subject'] = 'From Python'
>>> msg['From'] = fromaddr
>>> msg['To'] = to
>>> body = "This is the message content"
>>> msg.set_payload(body)

Thats all. Though some smtp servers needs a Date header too, to work.

>>> from time import gmtime, strftime
>>> msg['Date'] = strftime("%a, %d %b %Y %H:%M:%S +0000", gmtime())

Sending the message via the smtp module is even simpler.

>>> import smtplib
>>> server = smtplib.SMTP('localhost')
>>> server.sendmail(fromaddr, [to], msg.as_string())
>>> server.quit()

Absolutely.

server = smtplib.SMTP('smtp.sbcglobal.yahoo.com')
server.set_debuglevel(1)
server.login ('xxxxx','yyyyyyy')
server.sendmail(fromaddr, toaddrs, 'Subject:from python\n\n'+msg)
server.quit()

You have two newlines following the Subject: line. That inserts a blank
line, which terminates the headers. Everything else, including the From:
and To: lines, will be taken as part of the message body. I assume you
meant to use \r\n, but \n will work just as well and is less error prone.

print "Message length is " + repr(len(msg))

Easier is:
print "Message length is", len(msg)
More efficient is:
print "Message length is %d" % len(msg)
