I've previously assumed that would be fine, but Craig got me to worrying.
Anyone trying to check an 822 address like this (rightly or wrongly) is
going to get the wrong answer (I'd say it serves them right, but these
thing can be dificult to explain to other people sometimes).
This is why I wait until they say DATA to reject.
The way I do it. the above would of worked, BUT if they went any further
such as sending a message (with DATA) then it errors.
These are 821 addresses. This address is never used as 821-sender so
it can never be used to receive delivery notifications.
Are people trying to verify 822 addresses this way? Probably. In
general: no matter how idiot proof you try to make it, there's always
a better idiot.
Just my 2ct
Alex
