Two different senders of email are receiving NDR's with a notation refering
to “403 4.7.0 TLS Handshake Failed”. During the SPSSP1 Premium upgrade this
client added ISA2004. Most mail flows just fine. Is this a problem on the
SBS server? Does this have to do with the ISA SMTP filter? ...with the ISA
SBS generated self-signed certificate?

TIA

Are they trying to send encrypted mail?

The answer is/was ...:

The SMTP Virtual Server was corrupted. The solution was to create a new
SMTP virtual server instance and the rest of the related/affected settings.
First, of course, I had to stop the old/default one. Once the new instance
was running I had to remember to adjust the SmallBusiness SMTP Connector to
use the new VS for bridging. It all seems fine now though I have no reasons
for the SMTP becoming corrupted. ...which is kinda scary since there is no
monitor of it should it decide to act up again
