From the QMail Howto:
http://muse.linuxmafia.org/lost+found/qmail-howto.html#11

11. Starting qmail.
...
To check if the services have started, you can run ps.

# ps auxww | grep qmail

You should see several tasks running, at the very least qmail-send, and some supervisor processes. If these processes don't show up within a minute or so, you've probably done something wrong, and you should go back and retrace your steps.

Once the qmail processes show up in the ps listing, you can test local deliveries by following the instructions in TEST.deliver. Also, you can check to make sure your qmail-smtpd is listening by telneting to port 25 of the local machine.
.....

Ya gotta love those howto's!
