[Dovecot] (no subject)

Hey everyone, I'm trying version 1.0rc2, via the rpm at ATrpms.  I'm
running on CentOS
4.3 on an Opteron system.  I have this running stably on a 32 bit system, but
I'm
crashing constantly on a 64 bit system.

Here's what I'm getting in my mail logs when I try to log in via IMAP:

Can someone confirm whether this is a bug or not?

I believe this has to do with how the index files are written, with a 32bit or
64
bit offset. If you remove all the index files, etc from the mailbox when you
switch
between the two, or compile with the specific offset, it should work
fine.

Bug? I dunno. Maybe it could detect this?

Depends on how you have the UIDL format configured. Personally I use
maildirs and have the format be the filenames so I can continue to use
qmail-pop3d (for now). If you're using the default, yeah, I think that's
a generated id.

Another option would be to recompile dovecot on the 64bit system with
the --with-file-offset-size=32 instead of the RPMs. It is really  an
easy build. Personally, first I'd try removing the index files for my
own account and see if my mail gets re-downloaded. 

Please note that I've done very little on 64bit systems, so these are
mostly guesses. But I have compiled with --with-file-offset-size=64 and
had to remove my index files to avoid that crash.

Ah, so *that's* why I didn't see my reply appearing on the list! 
I'll repost so it gets
archived.
