[expert] Postfix: No route to host
I am having a problem on my LM 7.1 server running postfix. I need another pair of eyes to help me with this. I am getting entries in the /var/log/main.info like: Dec 2 21:15:17 server1 postfix/smtp[21898]: connect to ASPIRIN.DII.utk.edu[128.169.76.123]: No route to host (port 25) Dec 2 21:15:20 server1 postfix/smtp[21898]: connect to MAILHOST.CAS.utk.edu[128.169.76.44]: No route to host (port 25) which seems to indicate a routing problem and not a postfix problem. Also: [root@server1 mail]# telnet mailhost.cas.utk.edu Trying 128.169.76.44... Connected to mailhost.cas.utk.edu. Escape character is '^]'. Connection closed by foreign host. [root@server1 mail]# telnet mailhost.cas.utk.edu 25 Trying 128.169.76.44... telnet: Unable to connect to remote host: No route to host As you can see, I can telnet the host but NOT on port 25! Anyone have an ideal why this fails? TIA, Bill This is not an ipchains rule blocking output to port 25. Keep in touch with http://mandrakeforum.com: Subscribe the "[EMAIL PROTECTED]" mailing list.

Re: [expert] Postfix: No route to host
It may be possible that your ISP is blocking SMTP traffic. Some of the ISP's do that. To send mail, use their SMTP server as a relay. I think they don't want their customers to send mails directly to avoid spam. Balaji On Monday 04 December 2000 12:14, you wrote: I am having a problem on my LM 7.1 server running postfix.

RE: [expert] Postfix: No route to host
I solved it. I called my ISP and it seems they just started blocking port 25 to stop spammers from using their systems. I wish they had sent my a message and save me a few hours trying to figure out what I screwed up.

Yep, you were right. They just started blocking port 25.
