Custom signature not working as expected

L1 Bithead

Hi Guys

I have the follwoing issue:

I have a policy rule where I allow  smtp flow! On this rule I have a vulnerability protection profile. In this pofile I have 2 rules:

- one rule which is supposed to allow emails with bb.com in the subject

-the second one is the one which is denying emails from aa.com

Both rules have custom vulnerability objects:

test_aa.com

test_bb.com.com

The idea is to block emails with aa.com in the subject but allow emails wich have aaa.com and bb.com in the subject.

I'm trying since some time and I think now is the momment to ask for help as I don't uderstand what is happening!

When I send emails with only aa.com they are dropped correctly but alos when I send with aa.com and bb.com in the subject. As you can see I used the order and the one with allow bb.com is before the one denying the aa.com.

Is my understanding about the vulnerability profiles not correct or is just a regex issue?

Thanks for the help!

Marius
