Hi,

I'm using Dovecot (dovecot-0.99.10p0) on OpenBSD-3.4 for few weeks now.

When i connect to my IMAP account the connection is often closed by dovecot when i try to delete mails.

I can see messages like this in log:

Feb 29 18:47:00 po imap(mat@reynerie.org): Corrupted binary tree file /home/mat/Maildir//.INBOX/.imap.index.tree: used_file_size larger than real file size (1772 vs 1556)

I tried to remove all index files, but the problem still occur. I also tried Maildir and Mbox, same problem (i can't remember if the log are similar with mbox, if needed i will test again).

I have ktraced the imap process and try (succesfully) to reproduce this behaviour: I have re-send a lot of spam and delete few of them from mailbox until the problem occur.

All logs/kdump/config are here: http://mat.reynerie.org/dovecot/ In the kdump file, the problem is visible at the end, Dovecot is compiled (via ports) with:

env CFLAGS="-I/usr/local/include -L/usr/local/lib" CONFIGURE_ARGS="--with-ldap --with-ldap-includes=/usr/local/include --with-ldap-lib=/usr/local/lib" make

Searching the mailing list archives, i have not found any solutions.
