I have done a bit of experimenting with the SMTP relay and it would seem that the SMTP Recipient Verification option doesn't work quite as I would expect. I would have thought that it would query back to the inside SMTP server to determine if a valid address is being requested Then reject the message if the address was invalid, instead there is a long pause but no matter what address I enter it is eventually accepted.
Can anyone else reproduce this behaviour?
