First of all, I'd like to thank everyone for their help. (This thread was also posted to comp.mail.headers and comp.infosystems.www.authoring.cgi.)

I had several people ask about this (some in e-mail and some in the newsgroups). I kid you not. I used the smtplib on my web host and it sent through messages with no Message-ID. (Why would I want to generate the Message-IDs if I didn't have to?) Since this appears to happen at least some times, I figured I'd have to just go ahead and make the message ID, since once I send the message off, my script is done, and there is no way for me to retro-actively grab the message back if it didn't get a message-ID and then stick one on. How common this is...I don't know. My host is using a proprietary configuration of Qmail. I'm surprised as you all are. : :>What is a good way for my script to generate Message-IDs?

All good suggestions. Someone also suggested using the mimetools module choose_boundary method (from Python). Interesting idea. I would also like to thank Brett g Porter who posted the following link in comp.mail.headers: http://www.jwz.org/doc/mid.html Besides giving some very nice tips for generating message-IDs, I found some other really interesting stuff on that site, too. (Like an algorithm for threading news articles and other assorted stuff.) -- Sheila King http://www.thinkspot.net/sheila/ http://www.k12groups.org/
