Squirrelmail on centos5?
 

I installed via yum, the following things:

Dovecot
Squirrelmail

I can find and start the dovecot service, but I cannot find squirrelmail service in the services menu? I am using the gnome gui...

But when I go back to try and re-install it in add/remove programs, it shows up with a checkbox and I can't install it...

Anyone have easy step by step instructions on how to install it? The guide I read said all I had to do was yum it and go to localhost/webmail .. but when I go there, I get a 404.... apache is started and working

help!

Squirrelmail does not seem to be a service rather is a webmail client. You need to configure apache as the site shows it to be written in PHP. And for that you will also need to configure your mail server to know about it.
And you do not seem to have installed any smtp server.
