Email Filter Wildcard?

[noimad1]

Anyone know if you can setup a filter with a wildcard.

For example, I have a customer that is being spamed by someone who is using:

chrisff@theirdomain.com
chris22@theirdomain.com


Basically changing the couple of letters after chris. And I can't use "theirdomain.com" becuase the spammer is spoofing the customers domain in there.....


So I would want to filter like:

chris*@theirdomain.com

Try it and see. For a definitive answer have a look at the filtering guide over on exim.org.
