What does IronPort do if I send email to an IronPort protected address 
that happens to be "[email protected]"?

Does it check first to see if it exists, and refuses to accept it if the 
address doesn't exist?

Or does it throw the email away after receiving it?

Or does it send it back to either the "From" address or the 
"Return-Path"?

Only the first of these behaviors is reasonable.

The second will throw away important email just because the address has 
been misspelled.

The third creates back-scatter spam.  For examples/reasons, see:

http://en.wikipedia.org/wiki/Backscatter#Backscatter_of_email_spam

From the IronPort webpage:

"End-users directly access the IronPort Spam Quarantine to check and 
manage messages, or review email digests that are mailed to them 
periodically."

(http://www.ironport.com/technology/ironport_antispam.html)

So what IronPort does is converts spam you have to look at into 
(surprise!) spam you have to look at.

Sorry, but I wouldn't even take that solution if it were free (which is 
why I don't use SpamAssassin).
