I have setup CentOS 5.3, PostgreSQL-8.3.7 (Client), Postfix-2.3.3 (with
PostgreSQL support) & Dovecot-1.1.14.
1. Postfix is installed,configured & Tested (telnet localhost smtp).It
worked.
2. Dovecot is installed & Tested (telnet localhost pop3). It worked.
3. Dovecot-SASL is installed. Testing FAILED.
"telnet localhost smtp" connects but when I try "telnet mail.tib.com
25", I receive the error:
---------
[r...@rs1 ~]# telnet mail.tib.com 25
Trying 65.103.190.107...
telnet: connect to address 65.103.190.107: Connection refused
telnet: Unable to connect to remote host: Connection refused

I have tried "telnet mail.tib.com 25" with firewall disabled and with
opening the SMTP port. I have tried connection from another LINUX
machine with the same subnet (65.103.190.105). No success.
/var/log/maillog & /var/log/messages have no ERROR messages to tell why
the connection was refuse. HELP.
I have researched the Internet. There are quite a few discussions on the
same ERROR but none with my installed setup. In any case, I went ahead
and tried few suggestions listed on the Internet with no success. There
is one or more setting which are causing this error. due to my limited
knowledge, I have no success in find out which one.
Any suggestion is highly appreciated.
