Looks like they're probably running UW-IMAP and that the mail server is
returning a mailbox that isn't valid.  In any case, you can see that the
mail server is returning an error.  You might try using the folderfilter
option to restrict the set of folders processed to only those you know
you care about.

I just confirmed this with the latest version in the arch repository. Anybody
confirms it?

First question: have you read the "UID VALIDITY PROBLEM" section in the
manpage or manual, and followed its suggestions?  If so, what happened?

Yeah, I did when the problem first occurred and it persisted. It occurs
whenever I save a message in any two-or-more-level deep mailbox
(.imap/whatever/mailbox). The imap server for this account is UW-IMAPD.

After this, I tried the same (move a message with mutt "s" command into
.imap/whatever/mailbox) and the same problem happened. Unfortunately, I don't
have access to the imap server of this account.

Thanks,

UW-IMAPD is notoriously troublesome with OfflineIMAP, and the problems
lie with UW-IMAPD, not OfflineIMAP.  OfflineIMAP uses features that Pine
doesn't, and apparently UW never really bothered to test those.  It is
probably that you will have to work around by not using a
two-or-more-level deep mailbox on the server.

Thanks, I used the following folderfilter rule, which seems to have done
the trick:

folderfilter = lambda foldername: re.search('^\.',foldername) == None

Yes, it is, though mostly in a fixing bugs way.  As far as I'm
concerned, it's "done" and there aren't major new features to add.

However, I may at some point write my own IMAP client library and
re-implement it in terms of that.

Hi John,

Oh, ok - well, I guess that would explain why devel seemed to stop 
around June of last year. I like that! Software that actually reaches a 
'done' stage! What a concept, huh? ;)

I was especially interested in this comment from the manual:

"OfflineIMAP is SAFE; it uses an algorithm designed to prevent mail loss 
at all costs. Because of the design of this algorithm, even programming 
errors should not result in loss of mail. I am so confident in the
algorithm that I use my own personal and work accounts for testing of 
OfflineIMAP pre-release, development, and beta releases. Of course, 
legally speaking, OfflineIMAP comes with no warranty, so I am not
responsible if this turns out to be wrong."

I am more concerned about data loss than I am performance, so this was 
comforting.

Also this:

Well, OfflineIMAP is designed for personal use rather than syncing two
whole servers.  So the answer is -- this is untested, and there is no
automatic support for syncing an entire server installation.  You would
have to manually configure each account in OfflineIMAP.

Do I understand that the public IMAP server is not reachable via a fast
link from your internal LAN?

I basically wrote OfflineIMAP as a user frustrated with the performace
of using IMAP over the Internet.  Your users may be able to use it for
themselves individually.  Alternatively, more mail clients are doing
IMAP caching these days.  I think Thunderbird and KMail finally are, and
Mac Mail.App has for quite some time.
