E-Mail / Cannot connect to SMTP server "host ip" (host ip:25), NB connect error 1460

« on: January 24, 2015, 12:03:22 AM »

Hi,

I can connect pop3 with thunderbird and other mail programs. But i can't connect to smtp. Postfix is working and listening 25 port. I couldn't find the problem.

[root@Centos-Host ~]# postfix status
postfix/postfix-script: the Postfix mail system is running: PID: 1269

[root@Centos-Host ~]# netstat -tulpn|grep 25
tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN 1269/master
tcp 0 0 127.0.0.1:10025 0.0.0.0:* LISTEN 1269/master

When i try to connect smtp, this error returns;

Cannot connect to SMTP server "host ip" (host ip:25), NB connect error 1460.

Here's the server info. Thank you.
