I am not using a random SMTP server. I'm using my ISP's SMTP server.

I have dozens of Googlemail accounts. I don't use any of them for SMTP. 
I use them solely for POP.

markfilipak.mozilla
The 'support-thunderbird at lists.mozilla.org' and 
'support-firefox at lists.mozilla.org' mailing lists echo my posts back to 
me. They are POPed by my Googlemail 'Mozilla' account.

markfilipak.windows+ffmpeg
The 'ffmpeg-user at ffmpeg.org' mailing list _does_not_ echo my posts back 
to me. It is POPed by my Googlemail 'Windows' account.

The only difference between them is that for 'markfilipak.mozilla', my 
'From' header is spoofed:
'From: Mark Filipak <markfilipak at bog.us>',
whereas for 'markfilipak.windows+ffmpeg', my 'From' address is not spoofed:
'From: Mark Filipak <markfilipak.windows+ffmpeg at gmail.com>'.

I didn't think about it before, but perhaps the spoofing is the reason 
'markfilipak.mozilla' is echoed back, eh?
