Let Filter Incoming Emails by Domain check for the From: header in email

Hi.

I have added a few domains to be blocked by the Incoming Emails by Domain filter but they are not blocked. Checking on this I see that the filter checks for the domain that is written on the "envelope-from" information, that is ok. But sometimes the "evelope-from" is not the same as the "From:" header and then the domain that is added to the black list doesn't work.

Would it be possible that the filter could check on both the envelope-from and the From:?

Doing this we will be really blocking the domains that we don't want.

Thank you.
