You must use two different servers to accomplish this.
ISA doesn't support two "public" interfaces.

Hi,

No, I actually do not want to load balance.  I just want one server to
send its data to and from the internet through one internet connection
and another server through the second internet connection.

That is, all Internal networks can talk to both servers (squid and
email) on DMZ's through ISA.
The squid server and email server also are protected by the ISA.
The squid server, however, sends data to/from through ISA to the
internet via an ADSL connection, whilst the email server sends to/from
the internet through ISA but via a Frame relay connection.

Cheers.
