Need to create forward for each site member - best way?

Hey all,

I need to create an email forward for each person who registers on my site. I seem to have two options:

1. Use catch-all address piping to a PHP script that locates the correct forward in database, and forward using PHP mail function.

2. Using a script that makes an actual forward like this: :: cPanel Email Forwarder Creator :: Free PHP Scripts

Can someone give me some guidance as to what may be a better/more reliable option?

Thanks in advance!
