[Dovecot] Index corruption with squirrelmail.

["Fábio M. Catunda"]

Hi.

I don't know if the problem is related with squirrelmail or not, but I 
started to have index corruption when I started to try squirrelmail.

Some informaton about my instalation:
dovecot 1.0.5-1 debian package with maildir
squirrelmail 1.4.9a-2 debian package

Some log information:

dovecot: 2008-02-27 08:39:39 Warning: IMAP(<please don't send spam to 
me>): fscking index file 
/var/virtual/contactnet.com.br/fcatunda/Maildir/dovecot.index
dovecot: 2008-02-27 08:39:39 Error: IMAP(<please don't send spam to 
me>): Unexpected transaction log desync with index 
/var/virtual/contactnet.com.br/fcatunda/Maildir/dovecot.index

I'm not pretty sure, but it looks like that if I keep my thunderbird 
open, receive a message and a rule move the message from INBOX to some 
other folder and then, finally, I try to login in squirrelmail I reveive 
a message like this:
Query: EXPUNGE

And in my log file the above message appears.

I already deleted dovecot.* files, but the error ocurred again.

Any suggestion?

Thanks!
