if you have a SPAM filter for outbound, it might be able to do it.

You could be sneaky and add the email address to that person's mailbox so they end up emailing themselves.... :) or create a new distribution list or something with that email address, and deny anyone from being able to email it. So the user will just get a bounce...

Very good idea. I've setup a Distribution Group and added a test email address to it... Within Security I have added myself and Denied Sent To. I have sent the mail and got nothing back however I'm aware this can take time to start working so will test again this afternoon and let you know.

The Distribution list is not working.

I have setup a DL with an external address and setup myself within Security as a Deny All (Start with Send to but that didn't work). I then added a PF to the membership to ensure I can track it if it does get delviered.

When I send to the email address it see it as the DL and deliveres it to the PF.... Should bounce back it should it not... I'm set to Deny All this should stop me from sending to it....

Any other Ideas....

Sorry, I kind of lost track of your posting.
The DL should work... I have tested it.

Don't bother with the security TAB. Go to the Exchange General TAB of the DL.
Configure message restrictions to  Accept Messages > ONLY FROM:
and specify yourself or you should even be able to put the DL itself... as the only address able to send to it. That way if they ask someone else to test it will fail also.

Sweet! it worked.

Now I have one more thing to add... my client wants not only a complete email address to be block but also any address at a domain.... Can you do this? i.e. catch all for *@domain.com = block

No need to close now as FDiskWizard picked up the case again.

Still need to create a catch all DL for a domain so I can block everything going to it.

D'oh.... I forgot about Global settings > Message Delivery > PROPERTIES... Recipient Filtering.
It's not something I look at very often. That should be able to kill a single address or a domain.
Just add: user@domain.com or *@domain.com under the Recipient Filtering TAB.

Can also block from something outside under Sender Filtering.
