redhat sendmail config

[Bluedoor]

Hi,

I'm running sendmail 8.11 on redhat and I'm trying to
configure sendmail to forward mail to a smtp server.

My mail server is "onsmail"

I configured "Smart" relay host
DSonsmail

But all mail that I send is going into queue. I can telnet to onsmail on port 25.

The mail queue says
(host map: lookup (yahoo.com): deferred)

What am I missing ? Could someone help !

gthampi,

Have you got a sendmail.mc file ? I've only started using sendmail on 8.12 so not sure about earlier versions. If so add the line

FEATURE(`mailertable')

Then create a file called mailertable in the same directory as the sendmail.mc file and add an entry like the following

domainname.com esmtp:[ipaddress of your smtpserver]

the entry in my file looks like

domain.com esmtp:[172.30.212.2]

You need the square brackets and note the format of the quote in the FEATURE line

You'll need to recompile the sendmail.cf file then by using

m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf (change the paths if needed)

and restart sendmail

If you haven't got an .mc file let me know and I'll have a look at my .cf file for you and see what we're using

Cheers

TalentedFool,

Thanks for the response !

I was able to resolve the problem.

I do have the sendmail.mc and I see the feature you're mentioning. I'll try your method next time.

I created a file service.switch in /etc/mail and put "hosts file" in it. The /etc/hosts should have the name/ip of your smtp server. And enabling smart relay will push your mail to the smtp server.

cheers !
