Problems getting sendmail to relay to exchange.

[Albion]

I am trying to get sendmail to relay email to my local exchange server. For some reason it's not doing anything with the e-mail onace it comes into the sendmail SMTP server.

Here is my Access database

localhost.localdomain           RELAY
localhost                       RELAY
127.0.0.1                       RELAY
hamprecision.com                RELAY
10.168.36                       RELAY
10.168.36.6                     RELAY

Here is my mailertable

hamprecision.com        esmtp:[10.168.36.6]

Here is my sendmail.cf

Here are the maillog logs when an email ment to be relayed comes into the linux sendmail server.

Does anyone have any idea why it isn't relaying?

Thanks

So I realize now that I had the wrong DNS server in /etc/resolv.conf. Once I set that correctly it started to send the mail to the exchange server. No I have a problem where the exchange server is giving me a

Jul  5 08:39:26 server sendmail[11429]: j65DdKs11427: to=<info@hamprecision.com>, delay=00:00:06, xdelay=00:00:05, mailer=esmtp, pri=30736, relay=[10.168.36.6] [10.168.36.6], dsn=5.7.1, stat=User unknown

Any ideas?

While this is the wrong group for your second question, are you sure there is a user with "info@hamprecision.com" as an assigned email address? Can you send mail to "info@hamprecision.com" within your Exchange organization?

I figured out the problem. It turns out that I needed to allow a relay for my local domain in the Exchange virtual SMTP server. Everything is working great now.

I do apologize for not asking in the correct place, but since many software packages have started to becomes integrated together in an environment it's difficult to draw the line between which software is at fault. So I feel it better to ask the entire question in multiple groups dealing with both software packages. Remember, not everyone uses JUST sendmail these days, and there are not Sendmail+Exchange groups.
