Probably you will want to adjust the smtpd_recipient_restrictions. It
depends on what you want to actually do. If you want to accept
anything and everything from servers in a particular network and
reject everything else, do something like this:

# Make sure that mynetworks contains the networks(s) that you want to allow
# mail from.
mynetworks = x.x.x.x/n

smtpd_recipient_restrictions =
  permit_mynetworks,
  reject

This will allow any mail from the special network and reject anything
else. Perhaps you want to allow anything from the specified network
and also authenticated connections. Do something like this:

smtpd_recipient_restrictions =
  permit_mynetworks,
  permit_sasl_authenticated,
  reject


Good luck.
