Our impression is that quite a few MTA's ignore the preference values on 
MX records
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".
