[Dovecot] Index corruption with squirrelmail.

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(): fscking index file /var/virtual/contactnet.com.br/fcatunda/Maildir/dovecot.index dovecot: 2008-02-27 08:39:39 Error: IMAP(): 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!
