receiving mail through a "standard" mail server setup

I’ve set up a web server for my company. Being a simple man I try to let the computer do most of the work if possible.

Through yast2 I went to network services–>Mail server and took the standard option.
My connection type is Permanent, filled in the outgoing server information and got to the incoming mail screen.

I told it to accept remote SMTP connections, open a port in the firewall and bypassed the downloading section since I just want to directly receive mail (I did however tell it I wanted a daemon to fetchmail). Told it to forward root’s mail to me and a delivery mod of Directly. And finished.

The system sends mail out but I can’t seem to receive any. What did I do wrong or what else do I need to do?

Thanks

As a rough guess you need to enable the user’s mailboxes. have a look at the mail server section in this:
