[Dovecot] configuration guidelines.

Our imap/pop service is moving from UW imap to dovecot 0.99.11 on RHEL4. This is for around 200 users with lots of different email clients, e.g.:

Windows: outlook, outlook Express, eudora, thunderbird, netscape OS X: mail, eudora, thunderbird Unix/Linux: evolution, thunderbird, pine, mutt Web: squirrelmail

Apart from the example configuration file, I can't find any guides for optimal values to use for dovecot's many configuration options.

A few that look like they might need changing are:

login_process_size = 32 login_process_per_connection = yes login_processes_count = 3 mbox_dotlock_change_timeout = 30 auth_count = 1 client_workarounds =

Does anyone have any pointers to reasonable values for those or other settings?

Thanks

Ian
