    Posted: 16 November 2004 at 10:23am

As an ISP I'm running into problems with customers whitelisting entries that other customers (different domains) don't want. Most notably religious related sites. 

Is Regex smart enough so that I can automate setting up a rule like this:

Whitelist if:
TO: = *@mydomain and FROM: = okuser@xyz.com

Of course I would have to add these to the top of the whitelist and the list might get long, but maybe I can do some selective whitelisting based on domain.

IS this possible? Anyone done it? Never used Regex but from what I've seen it looks doable. Want to make sure it is before I start working with it.

Best Regards,
Andy

The "AND" clause does not exist for this implementation of RegEx so what you are asking, if I understand it, con not be done.  You can, however, run a separate "instance" of spamfilter with it's own filters.  Several of us are doing this.  I, too run an ISP and I understand the issue and this is the solution I am using for our domain customers that want either more or less filtering than our "standard" rule sets.
