What matters is what server you connect to, and how it is configured to handle the envelope you give it. Mail forwarders ought to query a DNS for the "MX" record (on Linux, "dig domain.com mx" for that info) and forward the mail to one of the specified mail exchangers for that domain, regardless of what server you actually connected to for the initial delivery. Not sure this is relevant in your case, but it seems a likely candidate, since smtplib.py does not (and should not) be looking up MX records for you, as far as I know, while the "mail" utility might. -Peter -- http://mail.python.org/mailman/listinfo/python-list
Re: smtplib does not send to all recipients
OK, I've discovered the lost messages, but I'm still slightly confused as to why they ended up there. The messages were being delivered to the local machine, box1.domain.com, even though I was addressing them to @domain.com. My past experience with smtp mail has been that if I addressed the domain explicitly, the mail would not stop at the local machine. This is in fact why the 'mail' utility is working. If I use 'mail' to mail something to with no domain, it goes to the local machine, as I would expect, but addressed to @domain.com, it goes to the corporate server. So why does smtplib deliver to box1.domain.com? If the local smtp at box1.domain.com is configured such that this is correct behavior, I guess I'd expect the 'mail' utility to do the same thing when handling address @domain.com. By the way, the long vs. short usernames was a red herring. Those with .forward files were getting their mail. -- http://mail.python.org/mailman/listinfo/python-list

I assume mail is using sendmail under the covers, which is doing the same negotiation with the same SMTP server? The facts would appear to suggest that both sources are accepted by the local SMTP server - as long as you are positive both chains are indeed contacting the same server. Ethereal could show you this. A possible scenario would be that the downstream SMTP chain is somehow discriminating against the Python-originated messages. Logs should give evidence here. So, unless it's a simple typo and you are using different (email or SMTP server) addresses that you think are the same, see my original response, which included and you need to take the matter up with whoever runs the SMTP server. Are you sure the address is actually valid? Evidence for and against? These things are a pain, but with patience you can usually track them down. You could try explaining to a stuffed toy, or a sock on your hand, exactly why there can't be anything wrong with your code. My wife's bears are very forbearing [n.p.i.].

smtplib does not send to all recipients
Here is a snippet of code which does not send to all recipients. However, it also does not inform me of this error. My suspicion is that this only fails for users with longer usernames. The two I seem to regularly fail on have 9 and 11 characters respectively. Most users have names <= 8 characters. domain = "myDomainHere.com" admin = "[EMAIL PROTECTED]" % domain adminFull = "Full Name Here <%s>" % admin def mailMsg(text, subject, sender, recipients): # From: and To: headers at the start! if not sender: sender = adminFull elif not sender.endswith(domain): sender += ("@" + domain) addresslist = [] for name in recipients: if not name.endswith(domain): name += ("@" + domain) addresslist.append(name) msg = "From: %s\r\nTo: %s\r\n" % (sender, ", ".join(addresslist)) msg += "Subject: %s\r\n\r\n" % subject for line in text.split('\n'): msg += "%s\r\n" % line.rstrip() try: server = smtplib.SMTP('localhost') server.set_debuglevel(0) failures = server.sendmail(sender, recipients, msg) if len(failures): safeMailMsg("%s\n\n%s" % (failures, msg), "ttLadder: sent with failures", [admin]) server.quit() except smtplib.SMTPSenderRefused, sndErr: safeMailMsg("%s\n\n%s" % (sndErr, msg), "ttLadder: sender refused", [admin]) except smtplib.SMTPRecipientsRefused, rcpErr: safeMailMsg("%s\n\n%s" % (rcpErr, msg), "ttLadder: recipients refused", [admin]) except Exception, xcp: safeMailMsg("%s\n\n%s" % (xcp, msg), "ttLadder: other exception", [admin]) return The safeMailMsg() routine uses os.system("mail..."). It works but it is not sending me any error in this case. When I test by sending the same mail to myself (7 characters) and a long name (11 characters), I receive the e-mail but the other user does not. However, the header in the mail looks correct and if I do a "Reply-all" it will happily send the mail to both of us. Is this a known problem with older versions of smtplib? I'm using Python 2.2.2.
