Hi folks,

I would like to use sendmail as a relay, but would like to rewrite all

What's the easiest way to do this ?

Thanx,

Herb

I posted this yesterday in response to another guy wanting the same
thing, but maybe your search didn't find it.

  This is only moderately tricky, but there are several steps.

1.  Find and install the sendmail source stuff; you will need to
   end up with a batch of files in /usr/lib/sendmail-cf.  How to do this
  depends a great deal on which distribution you have access to.
  You will also need to have the  m4  preprocessor installed; mine
   is in /usr/bin/m4

2.  In /usr/lib/sendmail-cf/cf/  you should find a bunch of *.mc files.
    Choose one that has  OSTYPE(`linux') in the first few lines, to use
    as a starting point.  (Mine is named redhat.mc).  Add the following
    lines to this, just above the spot where HACKS(...) begin to appear.
        define(`LOCAL_RELAY')
        MASQUERADE_AS(mydomain.net)
        MASQUERADE_DOMAIN(mydomain.net)
        FEATURE(masquerade_envelope)
3.  Following the directions in /usr/lib/sendmail-cf/README, run  m4 to
    generate a sendmail.cf   file (your choice of names),  and then TEST IT
    using the sendmail -bt  option.

4.  I think I also needed to create the file   /etc/sendmail.cw    which
   contains the various names by which my server should be known to
   sendmail.  I have two lines in this file:  the ONE TRUE NAME for
   the host (its A record, per DNS), and   mydomain.net, in your terms.

1- Just add the following lines in your sendmail.cf:
     Djsomewhere.com
     Fw/etc/sendmail.cw

2- In sendmail.cw put the hosts that will use the relay such as:
    host1.somewhere.com
    host2.somewhere.com
    .
    .
If your hosts are not qualified names (fqdn) use the hosts file
like :  192.168.1.1    host1.somewhere.com
           192.168.1.2    host2.somewhwre.com

Hope this helps
