hi,

running dovecot-nightly on netbsd, just rebuilt for testing. for quite some time now (about a month) i'm getting these:

==snip== Feb 26 20:38:20 hostname imap(tom): Corrupted index file /home/tom/Maildir/.INBOX/.imap.index: No unseen messages found with first_unseen_uid_lowwater 25260, seen_messages_count 12, messages_count 18 ==snap==

when this happens, my client is unable to display 'subject' and 'from' anymore - as i'm using IMP (http://www.horde.org/org/) as webmailer mainly i can't say it happens with other clients.

restarting dovecot doesn't change anything, i have to delete .imap.index.* from maildirs files to get it working properly again.

i tried various cache settings and even disabled caching, without any noticeable effect.

any hint? need more info?

-- many thanks for the good work, TOM
