Help Setting Email

I installed ispconfig on Centos 4.2 distro
By default it asked me for Postfix as mail service,

Now when i logiin to ispconfig i can see the mail is up
but pop3 service is down, I went back and saw i didn't have dovecot so i installed it manually, Still it shows the same thing.

Issue is getting any emails/ sending emails

Can someone advise on this.

 

Did you start dovecot?

Code:

/etc/init.d/dovecot start

What's the output of

Code:

netstat -tap

?
