Hi

I've a small LAN (50 hosts), and a Postix that
works as "mail gateway" .

The problem is that somtimes, diferents "confused" clients
starts to send 5 or 10 mails / second during some minutes.

Of course, after that "attack" to Postfix, the result
is a mail queue full of no genuine mails...
and this is a DoS attack to my postfix

There is a way to solve this ?

Can I put a rate of -let us suppose- 10 mails
by minute ??

I've:
        Postfix 2.X
        SpamAssassain
        Amavis
        Clamav

Thank you.
bests

andres
