[Dovecot] login process died too early

Hi ! I have dovecot working on a SUSE 9.0 machine. Everything works fine. When I boot, I get this message: snip............. Dovecot starting up Login process died too early-shutting down snap........... rcdovecot status : unused

a rcdovecot start starts dovecot. What can I do to start dovecot when I boot up ? Adrian Roye
