Hi,
I was wondering if someone else has happened before, recently got an odd email which was spam, i was curious how it went by when i saw the headers it seemed that did not go thought filter, after doing these steps it seems that the attacker was using telnet 25 to send the email is there a way to block that?
This is the PMG gateway
