I have my webmail application tied to Postfix / Dovecot server & now for some reason the IMAP sessions oddly time out throughout the day and then logging back into the mail system over the web is painfully slow. The only thing I've seen that fixes it is to reload the Dovecot daemon in Linux: .. I'm running Dovecot-1.0.7-7.el5_7.1.
That's rather old. Might get solved simply by upgrading. You could try if using high-performance mode of login processes helps: http://wiki.dovecot.org/LoginProcess
Another reason might be your PAM setup.
