[vox-tech] smtp question - blocked ip

[Steven Peck]

ummm...email at work is MS Exchange and that works well enough protected =
by
an SMTP relay on the DMZ.

Existing Enterprise smtp relay entry point is also a Win32 solution that =
is a
cheap (cheap as in piece of crap) inflexible one at that.  A Linux =
solution
using Postfix or Sendmail has been proposed but is unlikely to be =
approved.
It is still under review at this point.  My existing SMTP relay is crap.

So install a bounce handler that rejects originating IP's into your
system.  Set it to have a bounce/delivered ratio low enough that they =
only
get 100 or so emails through per ip they abuse.

I've recently set something similar to this up and it's all but stopped
stupid spammers cold.
