Sorry... Red Hat ES4 (2.6.9-42.0.2.EL), latest dovecot CVS 20060926.

login_process_per_connection = no
login_processes_count = 3
login_max_processes_count = 10
login_max_connections = 4000
login_process_size = 64

Also added this to the dovecot init script to allocate more file descriptors to dovecot:

start() {
        echo -n $"Starting $prog: "
+       ulimit -n 16384
        daemon /usr/sbin/dovecot


Also, seeing this error occasionally...

Sep 29 11:34:15 director4 dovecot: imap-login: SSL_write() syscall failed: Bad file descriptor [166.137.221.91]

Maybe nothing to worry about now that I have increased "login_process_size".  Checking with customers to see if the Outlook IMAP SSL disconnects are still frequently occurring.

Thanks,
Bill
