configuring relay

Abdullatif M. Abdulla — Wed, 21 Jan 2004 08:14:00 GMT

We have 10.20 server (clustered). and we have an NT mail server. We want to send mails from the hp server to external world through the mail server. So the the Nt server will be a relay.

How to do that and what configuration files are involved.

1- I have added the NT server in the HP /etc/hosts file as mailserver.
2- I have add the relay server name in the sendmail.cf file DSmailserver
3- Stoped and restarted the sendmail.

But no progress

Can any one urgent help me.

I do not know what is to be done on an NT node but if it was a nuix node you would really need to add your hp node name on the relay-domains on the relay server..

There should be some way to add the HP node to the NT machine's authorised list of relay-hosts ;

All the best

Can the 10.20 server resolve external domain-names?

To test just put an external domain in the servers hosts file a fake IP will do:

1.1.1.1 testdomain.com

Just send another mail to the external mail acount and check if the mail is send and recieved.

Check if the HP server also resolves the relay server correct (nslookup)

Do you get any error on the "postmaster" mailbox or in /var/adm/syslog/mail.log (or wherever syslog sends mail.* messages) ?

Is it possible that the server refuses e-mail with incomplete or incorrect envelope "From" addresses ? Check with "sendmail -f".

Diagnostic:

sendmail -v -d8.99 -d38.99 someone@somedomain.net

type some text

.

You will see detail and get the problem.

I am wondering if the NT mail server is configured to allow relay from your HP boxes IP address.

Did you try to put thuraya.com(can be a fake ip) in your /etc/hosts file, it looks like its failing on resolving the domain.
Check the /etc/nsswitch.conf for name resolving order.

I think the problem is that your host cannot resolve hostnames in the To: address, and, unless you can fix that, you need to rebuild a new sendmail.cf with the following in the macros:

FEATURE(`nocanonify')
FEATURE(`nullclient')
define(`MAIL_HUB', `relay.domain.')

and also possibly, depending if you use sendmail 8.9 and your host is a relay:

FEATURE(`accept_unresolvable_domains')

Please check the sendmail documentation and http://www.sendmail.org/ for details.

This should be
define(`SMART_HOST', `relay.domain.')
