--- Comment #2 from Kyle Auble kyle.auble@zoho.com --- So Jeremy let me know that the same patch I sent last Friday started blasting wine-devel again. He mentioned that it was stuck in the exim retry queue. I've sent a support request to Zoho to see if they can tell me anything from their end; once they get back to me, I'll report any useful information.
I don't know details about how the mail system is set up, but if a queue in exim is where the message was lingering, my guess is the SMTP connection between the MTA and Zoho is specifically where things go haywire. Wouldn't that also explain why the patch queue sees all the repeats while mailman understands it's just one message? I've edited the bug name to reflect the new hypothesis.
I also tried googling for similar bug reports, and I really couldn't find anything. The one that seemed possibly related was that apparently using 'format-patch' and 'send-email' in tandem can sometimes duplicate headers: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=593542
I know Jeremy mentioned at one point he thought the messages themselves might be garbled. If this turns out to be the problem, I'll just add a note on the Submitting Patches page.
The only other things that jumped out were some discussions of how greylisting works on exim, which reminded me of the 4xx messages I got. For now though, that's all I have.
