Sendmail Help Needed

RT Users

Hello,

I’ve installed RT on a RedHat 7.3 system using MySQL. It’s working except that when RT tries to email a message to the queue watcher, it generates the following error:

The original message was received at Wed, 10 Jul 2002 16:54:18 -0400
from apache@localhost

----- The following addresses had permanent fatal errors -----
mkinsman@airolink.net
(reason: 501 5.1.8 mkinsman@airolink.net… Domain of sender address apache@mgt.airolink.net does not exist)

RCPT To:mkinsman@airolink.net
<<< 501 5.1.8 mkinsman@airolink.net… Domain of sender address apache@mgt.airolink.net does not exist
554 5.0.0 Service unavailable

Can someone send me a clue? I’ve made RT work very will with QMail, but I’m hoping to just use sendmail for this installation.

Thanks much!

Looks like you haven’t got a DNS lookup for mgt.airolink.netFrom: Darren Ellis

this is part of sendwhale’s UCE checks <check_mail>. Your destination
mail server (which obviously, from the error, is sendmail> basically
doesn’t know about the host:

mgt.airolink.net

so either add an A or MX record for that host into the airolink.net zone

or add it to /etc/hosts and make sure /etc/nsswitch.conf is

hosts: files dns

ON the mail server that’s rejecting the message

or change your masquerade as in sendmail.cf to airolink.net

there’s a few ways to fix it, but one of the three is the easiest…

hope that helps…
