Unable to send mail from linux server to outside using Sendmail

abhilashop · 06-01-2011, 10:29 AM

I have configured Sendmail client to send mail to outside network ( Within local domain ), but i am unable to send any mail as i am getting the following error,

[root@cclx10 mail]# cat test |sendmail -v abhilash-o.padmanabhan@hp.com
abhilash-o.padmanabhan@hp.com... Connecting to [127.0.0.1] via relay...
abhilash-o.padmanabhan@hp.com... Deferred: Connection refused by [127.0.0.1]

I have the following configuration in my "/etc/sendmail.cf" file

# SMTP daemon options

O DaemonPortOptions=Port=smtp,Addr=15.146.237.113, Name=MTA

And netstat is showing that sendmail is listening on Port 25 on the IP address which is mentioned.

[root@cclx10 mail]# netstat -an |grep 25
tcp 0 0 15.146.237.113:25831 0.0.0.0:* LISTEN
tcp 0 0 15.146.237.113:25 0.0.0.0:* LISTEN

Kindly let me know if anyone has any idea...

Thanks

Hi,

Your sendmail is listening only on the public IP. If you want to make it listen on every available interface (including local loopback 127.0.0.1), you need to edit sendmail.mc and use:

Code:

DAEMON_OPTIONS(`Port=smtp, Name=MTA')dnl

Then rebuild sendmail.cf
