You could issue a new recipient policy to easily roll out/add to every
user a second addy and make it the default smtp address.
On the exchange server you would need to make sure that'll
"listen/relay" emails for this new domain.

By invalid, do they mean incorrect/missing reverse DNS or even non MX
record?

If you have a separate Unity installation.. I am wondering where/how/why
you would be sending emails to though !?

Someone correct me if I am wrong with the above.
Cheers

PS: if you don't send emails to the public world.. Just make them use a
DNS server on the barracuda that has an entry for your domain... Still
don't get it why/how you'll be sending emails, as if it's a non valid
domain, u won't be able to receive any anyway ;)
