How to do a regexp

[Bruce A. Petro]

Hi - I'm new at regexp's and don't know how to do this...

The main question is from procmail regexp I did that is
not working.  I want it to find all mail where the TO:
contains "@about.com" ("[EMAIL PROTECTED], [EMAIL PROTECTED]).
Any suggestions why its not working?
:0:
* ^[EMAIL PROTECTED]
about.com

If anyone can help - I'd really appreciate it!
Thanks,
Bruce.
