Hi all,
I install postfix, dovecot and squirrelmail in my ubuntu.
when I login squirrelmail , I saw this message.
"Error connecting to IMAP server: localhost.
111 : Connection refused"

My /var/log/mail.log is
May 15 14:20:33 tkfsh postfix/master[8097]: terminating on signal 15
May 15 14:20:34 tkfsh postfix/master[8491]: daemon started -- version 2.9.6, configuration /etc/postfix

How can I solved this problem?
