qmail on dedicated server
 

All,

We've got a dedicated server with 1and1. We've been using the server for receiving email for a couple of months now, but we now want to use it to send mail too. The only problem is, when I put mail server into the smtp field in my email client, I get an error message telling me that it was unable to connect to the server.

the mail server we're using is mail.ourdomain.com which has been working fine for receiving email.

I've checked in the plesk control panel and requests to qmail are allowed.

How do I check to make sure that qmail is running? and what port its using?

Thanks

If you run:
netstat -nlp

It should show you if something is listening to port 25. You may also need to check your firewall:
iptables -nL
