Our impression is that quite a few MTA's ignore the preference values on MX records
How about Domain.com IN MX 100 spamtrap.domain.com
And set up spamtrap as a real or virtual server, which might safely assume that mail directed at is either spam, or mail from broken MTA that doesn't deserve the privilege of sending mail to domain.com.
so you could lose a significant amount of legitimate mail. I've also seen MTA's that
would only attempt to deliver to the primary MX (lowest preference number) and never
try any secondary MX records.
It would nice if all MTA's conformed to the standards, however non-conformant mail
software has always existed on the Internet. That's why most people who write mail
software follow the mantra "Be liberal in what you accept and conservative in what you
send".
