Custom Signature for Email Headers

I am trying  to create a custom signature with the purpose of preventing malicious/phishing/spam emails with the firewall before it hits our mail gateway. For the most part we have been successful with this technique but I am struggling with creating a signature to essentially work as a wildcard. If anyone could take a look at my scenario and provide any feedback it would be much appreciated. Below is my example:


Scenairo: we are receiveing unwanted emais from the following email address


As you can see the consistent parts of this type email campaign is the I am hoping to come up with a signature using email headers to wildcard the 'abc, abcd,abcda, etc'  as I dont want to be writing individual signatures for each sub domain as this could include upto 15 different representations of 'abc'.


I thought this would work scanner@(.*)(\.domain\.com) but does not appear to be the case.pic.PNGpic.PNGpic.PNG
