Hello I'm trying to use postfix and amavis together on SuSE 10.1 and have a problem with postfix listening on port 10025 (this is not directly a security problem but as I need this socket to use amavis it is somewhat security related ;-) ) I reactivated the following line in /etc/postfix/master.cf and restartet postfix: localhost:10025 inet n - n - - smtpd -o content_filter= After that I run some commands #lsof -i -nP | grep master master 25767 root 11u IPv4 187669 TCP *:25 (LISTEN) master 25767 root 12u IPv6 187670 TCP *:25 (LISTEN) master 25767 root 72u IPv4 187753 TCP 127.0.0.1:10025 (LISTEN) master 25767 root 73u IPv6 187754 TCP [::1]:10025 (LISTEN) #telnet localhost 25 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. 220 mail-gw.src-bonn.de ESMTP Postfix but #telnet localhost 10025 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. For me it seems that postfix does not listen correct on port 10025 since the message of postfix is missing. I tested it with SuSE 9.3 and everything is fine. Anybody have the same problem and maybe a solution? tia guido
