Re: SMTP

Hi Andres,

OK, in that case you create an SMTP Protocol Rule that only allows your
SMTP Server to use it. You can use a Destination Set that contains your
SMTP server's address in it and apply that client address set to the
SMTP Protocol Rule. This will allow the SMTP server to send SMTP
messages, but no other machine.

HTH,
Tom

i dont want to filter to it, what i want is only to allow any smtp
traffic that leaves the network to go through my smtp server only.

Since the clients can access the email server directly, ISA can't
control
their access to it.

ISA can control access to this:
            INTERNET/MAIL-------[ISA]-------CLIENTS(LAT)
..and this
            INTERNET/CLIENTS-------[ISA]-------MAIL(LAT)
..but not this
            INTERNET-------[ISA/MAIL]-------CLIENTS(LAT)

..because ISA doesn't filter LAT traffic
