need to configure sendmail to send without hostname


I have a problem where I need to change how sendmail sends mail.  Currently, some external domains are rejecting mail because messages are sent from user@host.domain.com where it should be user@domain.com.

I found one site where someone posted changing Dj$w.hostname.com to Djhostname.com.  I did that and it didn't work.  When I sent mail to my account @acme.com it actually put the message in /var/spool/mail even though I don't have a local account.  I then sent mail to my hotmail account and it still showed user@host.domain.com (yes i did restart sendmail).

Anyone know how to remove the hostname so it gets sent as just @domain.com?

The following thread will help you to change from address on sendmail:

It says "I added the following options to the *.mc file I used to create the sendmail.cf file."

Is that assuming it was created from source instead of rpm package?

My previous question was based on post 5.

I created a test.mc file and put those 2 lines in there.  When I use it with m4 it fails.

$ m4 /usr/share/sendmail-cf/m4/cf.m4 ./test.mc  > /tmp/sendmail.cf
NONE:0: m4: ERROR: end of file in string

Those instructions failed on the m4.

I did find another page that was slightly different and got it working.
At first it still showed the hostname.domain.com but then near the bottom it stated it has no affect for root.  I used a normal account and the mail was sent using just domain.com
