Asa5505 still obfuscating mail banner with no inspect esmtp
I've tried it all. no inspect esmtp. no policy map. inspect esmtp tls with banner obfuscate off. i'm out of ideas. i always get 220 ******** when telnetting to mail server from outside. tried 184.108.40.206 and 8.0.5. any ideas?
cable modem -> asa5505 -> sa540 (router mode) -> mail server via static map policy for port 25 on asa5505
internal same subnet and different subnets works fine. works fine across site to site vpn. just get stupid banner when i access from outside.
policy map nat ip address is different than outside interface address. have other policy nats using 443 an 80 and they work fine.
