no such banner on telnet 10025


>What about telnet to Postfix port 20025; does that work ? Any clues in any log files ?
non postfix mail sever listens and responds perfectly on this port

logs are full of

connect to 127.0.0.1[127.0.0.1]: server dropped connection without
sending the initial greeting

messages

any idea ?
