How i can configure sendmail.

Mhost map: lookup (my domain): deferred

[Mel Burslan]

if your server is not a mail relay host, you will need to pass your messages to a mail relay to be delivered to their destinations.

To do this:

In your /etc/mail/sendmail.cf file, find the line starting with

DS

and modify it to look like this

DSmailrelay_host_name

you need to talk to your organization's mail administrator to figure out what this mailrelay_host_name is. It usually is a microsoft exchange email server. You also ask them to add your servr's ip address to authorized senders list.
