Configuration Question

Hello and Greetings my fellow comrades in this war on SPAM.

I have loaded, configured TMDA on my mail hub and I am testing it.

However, after reading the documentation it isn't very clear how the 
confirmation part of the process works.

For example, I send a message, and I get a reply back the mail hub to 
confirm or whitelist my Email address.

The problem I C though is that the reply address is tagged for confirmation.
(i.e. [email protected]).

If I send a confirmation to this address it obviously bounces as no such 
user exists on my mail hub.

Obviously the reply tagged address doesn't exist on the mail hub, and  
it bounces with user unknown.   I looked into the documentation further, 
but I do not see any requirements that I need to modify sendmail any 
further with regards to setting up inbound email confirmation or 
recognition.

I am puzzled because the test link on the site sends out a reply 
confirmation that does work with a tagged confirmation reply address, so 
it must work somehow.

So, my question is how does one go about modifying sendmail configs so 
that sendmail recognizes the inbound confirmation for whitelisting the 
address?

Or, is this a outbound template modification I need to do to redirect 
the confirmations to the original sender (i.e. [email protected]) for 
sendmail?

Thanks!
