Hello, I followed this nice tutorial here http://www.debian-administration.org/articles/275 and installed Dovecot without any error. Then, I followed this tutorial here http://www.debian-administration.org/articles/200 and installed the SquirrelMail. I am at the stage where you run a configtest to see if everything checks out. Sadly, my configtest is failing like this: I had already opened the port 25 on my iptables firewall like this: # iptables -A INPUT -p tcp --dport 25 -j ACCEPT So, I ran the following command to see if dovecot imap server was running... # netstat -tap and this is what i saw: Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 *:imaps *:* LISTEN 24173/dovecot While other server/programs on my server are running on a specific port (e.g. webserver on *:80), dovecot is running on *:imaps Is this correct? Is this what's causing my configtest to fail with SquirrelMail? First time playing with mail server + mail client. Please advice.
