Hi.

Your setup looks just like mine here, so i just checked my logs and i
can see that i have the same in the logs as you have.

I have fetchmail -> postfix -> maildir

and i have the mail client do the sorting too, which also has been
thunderbird for a period, and is now evolution again.

And this is the installation dates of dovecot, so it spans 3 versions,
don't have logs further back, so don't know if any older versions are
affected.

Wed Dec 27 13:16:16 2006 >>> net-mail/dovecot-1.0_rc15-r1

Sat Jan  6 09:08:37 2007 >>> net-mail/dovecot-1.0_rc16

Tue Jan  9 01:35:17 2007 >>> net-mail/dovecot-1.0_rc17

I have "mail_read_mmaped = yes" and the rest of the mmap stuff is
commented out.

the environment is linux kernel 2.6.19-gentoo-r4, on a x86_64 laptop.

And i haven't tried the snapshot yet.

Niki
