Email and Web forwarding server

I am looking at making an email forwarding server. I previous did this with PHP, MYSQL together with Postfix mail server. Clients could register domain names and then get websites and mail forwarded. Filemaker exported a flat text file which was cturned into a mail forwarding table, using a shell script. I want to make life simple. Store list of email addresses plus forwarding addresses in a file maker database and get Filemaker to provide the forwarding server:

[email protected] -> [email protected]

[email protected] -> [email protected]

etc

Also web forwarding, do 

www.123.com -> www.freeisp/myfreespace/index.htm

Does anyone have any simple (and cheap!) plugin which can do this? I can probably do the email it with 360works but this is quite expensive and is over kill for what I want. Any better solutions?

If I can set this up, I would also like to make a tiny uRL server. Since this is essentially a web forwarding service, this should be quite easy. I already own 2 three letter .uk domains.
