  • 1.  Testing an email is showing lost connection server

    Posted Feb 23, 2012 05:06 PM

    Hi everyone;

     

    I have configured the file /etc/postfix/main.cf with the following line:

     

    relayhost = 10.193.128.14

     

    after reset the postfix service and testing sending an email it is showing me the following message:

     

     

    [root@localhost postfix]# tail -f /var/log/maillog

    Could you say me if I'm configuring well the main.cf file?? or there is and issue with comunication with the mail server.

     

     

    Thank you

    According to the log it's pointing to 10.193.128.13 instead of 10.193.128.14.  Are you sure the main.cf file does not have any other relayhost entry or you verified it is indeed 10.193.128.14?

    See http://www.postfix.org/postconf.5.html#relayhost. 

     

    The way you specified things, postfix is going to look up the MX record for 10.193.128.14, which appears to be .13. 

     

    Use brackets around the IP address if you want to disable MX lookups.
