Mail server - setup virtual mail boxes

[satimis]

Hi folks,

AMD Athlon54 X2 512Kx2 socket AM2 3800
slamd64-11.0

Just completed installing the captioned OS with everything installed except GAME. This is an experiment. slamd64 is now running on the box.

I'm going to setup virtual mail boxes on this server, allowing my friends using the mail server sending and receiving mails. Please advise;

1) how to check whether sendmail is running and configured properly.
2) how to setup virtual mail boxes. Where can I find relevant tutorial.

TIA
