Hi Yang, You had Cyrus already running on RH9? Strong part isn't it? Here some hints. I personally find cyrus on FC2 a kind of easy to install, where are the times, where you had to compile this yourself (i better do not remember those days i passed with installation & configuration) If you would like something easier, really try dovecot. But since you are already running cyrus, try this first: -> in /etc/sysconfig/saslauthd is a line 'MECH=' - set this to 'MECH=pam' -> your imapd.conf seems right to me (it's the shipped default, isn't it? ;-) ) -> is saslauthd running? if no do: '/sbin/service/saslauthd restart' as you authenticate plain against linux-accounts. -> restart cyrus-imapd -> don't use the root-account for tests.... -> create a linux-user and in cyradm create the appropriate mailbox - otherwise you can login but there is no mailbox. -> test either with imtest or use 'telnet localhost imap'. if you get reply from cyrus (you will get, i am shure, just type 'a01 login username "password"' - the "" around the password are needed. cyrus will either display an error or something like 'a01 login ok'. HTH, let me know if its working or not.... Roger
