Hello,
I'm deploing a new email cluster using Dovecot over GFS2. Actually I'm
using courier over GFS.
Actually I'm testing Dovecot with these parameters:
mmap_disable = yes
mail_fsync = always
mail_nfs_storage = yes
mail_nfs_index = yes
Andrea,
We tried to use GFS2 + Dovecot(mdbox) but when there's many mailboxes and
mails,
it seem to get slow while dropping mail to the mailbox.
We tested with LeftHand storage by the way. So we switched to NFSv4.
Also, keep in mind that director those not detect when the backend server
fails.

Hi there Giles,
not really a solution to your problem, but a hint:
Try activating verbose_proctitle = yes in your dovecot.conf, restart service
dovecot and you might get more information (when the load is produced by logged
in users) - it gives you verbose information about which specific user
Hi,
Since upgrading our mail servers to Postfix/Dovecot, we've seen a rather large
increase in botnet brute force password attacks. I guess our old servers were
too slow to suit their needs.
Now, when they hit upon a valid user, it's easy to see what passwords they are
trying (we've enabled

Have you or anyone else tried fail2ban?
I haven't had any break-in attempts since going to Dovecot yet, But with

I'd recommend mdbox as well, with a healthy rotation size. The larger
files won't increase IMAP performance substantially but they can make
backup significantly quicker.
