(*) which does not mean SA is useless, as it was demonstrated
recently when an OS upgrade temporarily disabled amavisd (which is
what triggers spamassassin) and the SA-filtered spam came through. As
an order of magnitude, graylisting filters 80-85% of incoming mail.
The rest is about 50-50 ham and spam.

If you setup one and got one MX10 and MX20, the MX20 should be always
in sync with the primary MX, especially considering anti spam
measures, otherwise you will get spammed to death via the MX20. Doing
so is possible, but quite the hassle.

I've the same setup on both servers, and spamassassin works very fine.
I receive averagely only two spam/email to day, that with the new backup
MX become four. Is for this reason that I am looking for the way to bind
the activity of the backup MX to the up/down to the primary.
The solution suggested by Matus (Postcreen) seems to me interesting in
this sense. But now I have to deepen :-P
Very thanks Lucio and Mark!
