Sendmail error - Unable to qualify my own domain name

[Marty Steffens]

I've looked through numerous threads on ITRC, but I still can't seem to find the lucky combination to fix my problem.

Here's my error in mail.log: Unable to qualify my own domain name (mcha01) -- Using short name. Be sure to set domain name in Dj Macro in sendmail.cf.

Here's my configured files:
/etc/mail/sendmail.cf
Dj$w.meritcare.com
DSgwvgwia

/etc/mail/sendmail.cw
localhost
loopback
localhost
mcha01
mcha01.
mcha01.meritcare.com

/etc/hosts
172.25.200.57 gwvgwia.meritcare.com gwvgwia #SMTP

We're not using a DNS, per the vendor's request. I do stop/start sendmail after my changes, but still receive the same error.

Thanks in advance for any feedback on this!

Shalom Marty,

short name is not a fully qualified domain name and that is what sendmail is looking for.

You need to use the FDQN to get around this.

Try that and mail should at least get to the relay server.

Steven,

I thought setting the Dj$w line would take care of the FQDN. Or am I missing something else on it?

Thanks!

Shalom,

you need to go further.

/etc/hosts networking must support fdqn.

You may wish to set the hostname in /etc/rc.config.d/netconf to mcha01.meritcare.com

Then you want to go through a full m4 macro process to generate a sendmail.cf file from sendmail.mc

This will annoying as it is to do, get you through this.

The server receiving the mail also needs network support, hosts lookup or DNS to identify this server by fdqn.

It would be way easier if possible to just do DS mail relay, but some of these steps will be required regardless.

HP-UX 11.31 right?

Here is the solution

Dj$w.meritcare.com
DSgwvgwia


comment out the first line . There is no need of that

and put you relay will the fully qualified domainname in Fornt of DS

than check you /etc/hosts file whether fully qualified domainame is mention there or not

Than

/sbin/init.d

./sendmail stop
./sendmail start


Good luck
