Hello BoB,

Thanks for you kind assistance, your solution opened the SMTP:465 on the
postfix server.


But when i telnet 587, i can see 220 in response.
[root at jet postfix]# telnet localhost 587
Trying ::1...
Connected to localhost.
Escape character is '^]'.
220 mail.digital-infotech.com ESMTP Postfix (2.6.6)

But when i telnet to 465, i do not see 220 in response. is it normal?
[root at jet postfix]# telnet localhost 465
Trying ::1...
Connected to localhost.
Escape character is '^]'.

Thanks / Regards
