Email filter setup using condition Regex

[ab3victor]

I want to setup filter rule for incoming email using REGEX.  I need it to filter several email addresses such that user A OR user B can be selected from other users.  Please provide examples.  Thanks.

AFAICT Comcast has no documentation for Regex, and Open-Xchange, the company that supplied Appsuite webmail, has just one line of information about it:

• regex: Tests if a given regular expression matches with the value present in the specified field.

If you don't already know how to use regular expressions you might try a search like https://www.google.com/search?q=regular+expression.
