I'm sorry to hijack a thread to do this, but I actually had to reply to
someone in order to show you the symptom.

Before describing the symptom, let me give you the situation... I'm
running Claws-Mail 3.8.1 on Xubuntu 12.10. On the way out I just do
normal port 465 SSL to my web host's SMTP server. On the way back,
fetchmail grabs my messages from my ISP using IMAP (and erasing them on
on the ISP's server after retrieval), then delivers them to procmail,
which, based on filters, drops them into the correct directories of the
Dovecot server running on my desktop. Claws-mail then views all my
email on the IMAP server.

slitt at mydesk:~$ dovecot -n
# 2.1.7: /etc/dovecot/dovecot.conf
# OS: Linux 3.5.0-25-generic x86_64 Ubuntu 12.10 ext4

At the bottom of this email I'll put a copy of a typical full header on
a post from me.

Here's the symptom: Every time I reply to an OCLUG post, Claws-Mail
loads the *To* with oclug at mailman.oclug.org and the *CC* with
oclug at penguin.oclug.org. Unless I remember to delete the CC, this makes
me double post every time, and must be quite annoying to you all. This
happens *only* on OCLUG posts: None of my other mailing lists display
this symptom.

It's actually weirder than that, because although when I compose the
message the preceding is true, by the time I get the two messages back
they both say oclug at penguin.oclug.org.

This happens only with the OCLUG list, no others. I studied the full
headers of the two messages when they came back to me, and could
discern no difference in the two. What I did find, however, is that all
OCLUG messages have:

List-Post: <mailto:oclug at mailman.oclug.org>
Reply-To: Orange County Linux Users Group <oclug at penguin.oclug.org>
List-Id: Orange County Linux Users Group <oclug.mailman.oclug.org>

Can anyone tell me how to start narrowing down the cause of this

I've CC'ed the Claws-Mail list and the Dovecot list in hopes that maybe
they have some ideas. The fact that the rest of you don't post doubles
makes me wonder if it's a mail client thing (but of course, only for
