Hi Jimmy
If you have the necessary access to add plugins, the solution
involves
creating a custom plugin specifically for this checking and filtering
functionality.
Oh wow, great! Thanks a lot for that template!
A plugin is a fine solution for cases where the MX isn't a perfect
spamsign, but it is also possible for small numbers of bad MXs to handle
this absolutely outside of SA such as with check_sender_mx_access in
postfix, or less elegantly through hosts file entries mapping the MX
names to something your MTA will recognize as bogus.
The advantage to doing that outside of SA is that it allows you to
reject spam that you don't bother to actually receive.
