Ultrix sendmail MX question

[Marc Cohen]

Sorry if this has been answered already.....

It appears that 'out-of-the-box' sendmail under Ultrix 3.1 and 4.0 will
not use an MX record if the machine it is trying to connect to is within
the same domain as the sending machine.  This is true even if the
receiving machine is not in the sending machines /etc/hosts file and it
has to use bind to find the address.

For example:

on umvlsi.ecs.umass.edu

umvlsi% date | mail -v cohen at delta.ecs.umass.edu
 cohen at delta.ecs.umass.edu... Connecting to delta.ecs.umass.edu.tcp...

There is an MX record for delta pointing to omega.ecs.umass.edu.

Has anyone seen this and found a work around other than installing a
different sendmail or adding a new class to the sendmail.cf file to
intercept mail to those clients?  Also, is  there an Ultrix sendmail
available (VAX or MIPS) with debugging enabled so I can get more info 
out of /usr/lib/sendmail -bt.

Please reply to me and I will summarize if there is interest.

Thanks, Marc
