While helping a new member of this community with his install I wanted to do something I've never done before...
I wanted to bypass EVERYTHING, but create an exception rule that would only push inbound SMTP into the rack. This particular Untangle installation is a bridge in front of Exchange and it's only purpose is to act as a spam filter.
I'm doing the same thing with destination port rules, I have two of them 1-24, and 26-65535. But it's just not as easy to read as a general bypass everything rule would have been, with a rule above it scanning SMTP.
My curiosity, has anyone else needed this sort of bypass all approach first?
