Verify probes work in the same way as real email, except that they
are not delivered (with SMTP, Postfix aborts the transaction before
sending the DATA command).
It's just a bit on a message that says "do not deliver, send a fake
delivery status notification message". This was the least amount
of effort to implement, and it gives maximal realism.
So it does not matter if the address is plussed or aliased.
