I am writing a script that needs to send some emails. And I've used
smtplib in the past and it is pretty easy. But I thought, gee it
would be easier if I could just call it as a function, passing the
from, to, subject, and message text. So I wrote it up as a function
and it sort of works, but I get a weird error. When it runs it
inserts a "\t" tab character before each item during the send portion
(which I can see when I turn on debug). The end result is that I
don't get any body or subject in my emails. It works fine when I copy
the inside of the function and run it directly. It isn't a
dealbreaker, I can certainly just call it direct, but from a learning
Python perspective I'm wondering if anyone knows what exactly is
happening. I'm more interested in the why this is happening than a
solution (though that would be great too). Oh and if you could
explain it to me, with no CS background, that would be even better.
I am working on Windows Vista with Python 2.5.2 (activestate).
Thanks --Joshua
Snip of script (more or less a copy/paste from effbot):
fromaddress = '[EMAIL PROTECTED]'
tolist = ['[EMAIL PROTECTED]','[EMAIL PROTECTED]']
msgsubj = "Hello!"
messagebody = "This message was sent with Python's smtplib."
def send_mail(fromaddress,tolist,msgsubj,messagebody):
import smtplib
SERVER = "mymailserver.mydomain.com"
message = """\
From: %s
To: %s
Subject: %s
%s
""" % (fromaddress, ", ".join(tolist),msgsubj, messagebody)
print message
server = smtplib.SMTP(SERVER)
server.set_debuglevel(1)
server.sendmail(fromaddress, tolist, message)
server.quit()
send_mail(fromaddress, tolist, msgsubj, messagebody)
Output when called from function:
