a question

When I use 'sendmail -v user@foo.com' to test if sendmail.cf configured correctly, I will be told 'Deferred: Name Server::host name lookup fail'. I have added the NT exchange server name following DS, and I can nslookup/ping the NT exchange server name. How can I solve the problem? Please give help. Thanks.

sendmail uses different records from the standard nslookup. Try:

nslookup
set type=mx
foo.com
(exit to get out of it)

See if that works.

As Ron mentioned the relay server MUST have an MX record in DNS.
It must also have reverse lookup set. Ensure this by doing an nslookup on it's IP.

I was confused that the sendmail.cf file was similar to other several servers except that the version of sendmail.cf file is different. I can sendmail from other servers but I can't sendmail from this questionable server.Does it have relation to version consideration?
