Things seem to be RIPE for a change eh?
So, what exactly causes the assumption that mamba is supposed to be reachable from the outside, on Port 25? $ host -t mx ripe.net ripe.net mail is handled by 250 postlady.ripe.net. ripe.net mail is handled by 200 postgirl.ripe.net. Now, obviously, expecting anti-spammers to understand about MX records and how to read Received: lines might be asking for a bit much...
