I'm not familiar with SquirrelMail, but can't it work with an IMAP
server other than UW-IMAP?

Good.

Well, if you switch to a better IMAP server, you wouldn't have this
problem.

I am willing to do such a hack if this work is paid for, at my
consulting rate for Openwall software ($40/hour currently). This
service is explained at http://www.openwall.com/services/
I expect to be done in under 3 hours (the minimum for consulting work,
for it to be worth the "context switch" and handling payment).
If this is needed by more than just you (maybe Dan?), the amount paid
may be divided between several of you. With your permission, I would
make this patch free software available to everyone and would give you
proper credit for paying for this work.
Whether it will become a part of the official popa3d or not will
depend on how small I can make this change to be, re-arranging some of
the existing code first. But regardless of this, any paid work in
this area actually helps me dedicate more of my time to other free
software activities.

It's not hard to do in the trivial way. However, that will add much
complexity to the code. And I want to keep popa3d simple. I view
this simplicity of popa3d as a very important advantage.
The reason this will add complexity is that the message numbers in
mailbox and message numbers seen via POP3 will no longer match, and
the mapping between the two will depend on whether or not there's this
special message.
