I don't understand why you listed _two_ MX records. Remember MX records
just let the MTA know which machine to talk to, it's then up to the
receiving machine to accept the mail. What I would suggest is

my.net.work. IN MX 0 mail.ser.ver.

This will ensure that all mail to @my.net.work and @mymachine.my.net.work
will all go to mail.ser.ver. Then you must configure sendmail or its equiv
on mail.ser.ver to accept mail with the above addresses.
