Why my postfix and squirrelmail could not work right?
 

I encountered a question bother me for nearly two weeks.
I installed postfix+http+mysql+cyrus-sasld+cyrus-imapd+squirrelmail on fedora12 by cmooamd 'yum install'.And I test the demons status by cmd '/etc/init.d/xxxx status'.The status are ok.But I can't get the email sent by squirrelmail.Why?

Hi, welcome to LQ forums. What have you done to configure those services after you installed them? I guess there is a configuration problem somewhere. Take a look at the logs for clues (/var/log/ folder).
