Hi Jim,
Aha! I misread the question, since I'm so used to seeing the AUTH issue
come up. Of course, you're supposed to be able to use Secure SMTP, why
else would there be that option in the Secure Mail Publishing Wizard?
:-)
I seemed to recall this being an issue that was discussed on this list
in Feb 2001 but my memory has faded with age. I guess I need to set up
the scenario and see if I find that same problem.
Thanks!

Did I miss something?
TLS (SMTP-SSL) doesn't have anything to do with SMTP-AUTH?
AUTH is a user-authentication, while TLS is a data-obfuscation through
encryption.
BTW Tim, I liked your "selective SecureNAT" idea. Maybe you should join
the
ISA-author ranks?

Hi Tim,
Unfortunately, you can authenticate SMTP sessions if you use the SMTP
filter. This has been an issue for some time. I think they wanted to fix
this with SP1, but the SP was taking too long and maybe they'll address
this with SP2?

Greetings:
By default, the SMTP Filter does not contain the STARTTLS command
required
to initiate an SSL session over port 25 for secure SMTP transmission.
Even
after adding this command, the SMTP Filter does not seem to allow any
SSL
SMTP (SMTPS) to pass. Disabling the filter enables SMTPS to pass.
Is this by design? Has anyone been able to enable the SMTP Filter for
use
with SMTPS?
Thanks.
