We use them everywhere on our site. It's easy to find tutorials online of how to make them...the hard part is getting the server configured to actually route the mail to the correct place. You'll need to talk to your server admin about it. He or she will tell you how to set it up on their end.
If you want a simple route, check out:

I have never used those, but I hear they are simple to set up, etc. Let me know if those work out for you.

There are friends who pass like ships in the night, who meet for a moment, then sail out of sight, with never a backward glance of regret...Friends we meet briefly then quickly forget.
Then there are friends who sail together, through quiet waters and stormy weather. Helping each other through joy and through strife. And those are the kind who give meaning to life.
