[Dovecot] Index corruption with squirrelmail.

["Fábio M. Catunda"]

Some addional information that I found:

This problem started on 02/21/2008 when I moved a message that has id 
1191941480.M342094P9293V0000000000000903I003B9713_0.cronos from .Spam 
folder to INBOX and then moved the message back to .Spam folder.

Today this message looks to be causing the problem.... still! See some 
loggging:

dovecot: 2008-02-27 17:55:33 Error: IMAP(fcatunda at contactnet.com.br): 
Maildir /var/virtual/contactnet.com.br/fcatunda/Maildir sync: UID 
inserted in the middle of mailbox (8055 > 8042, file = 
1191941480.M342094P9293V0000000000000903I003B9713_0.cronos,S=3129:2,ST)

I don't know if it helps or not, but I believe that this is a good tip 
about the problem.

Thanks.
