Re: [SSHGuard-users] Postfix compatibility

When you get a few hundred relay requests spaces less than a second apart, I call it hacking. 

It is more efficient to  block at the firewall than postfix  rate limit via anvil.

They're not "hacking" Postfix.  They're simply trying to relay
through whatever they can.  Postfix is already doing the job it
was designed (and configured) to do.  Adding another layer, via
sshguard, would net you nothing except to increase complexity.
