Depends on if you have wildcarded MX records as well too.
The mail might never bounce. Who is to say a clever spammer wouldn't
setup a wildcarded series of MX records to point to their own SMTP
servers, and harvest the FROM/REPLY TO addresses and place them in to
their spam lists. (obviously the TO field is wrong, since it's domain
bounced - however I wonder if you could take the @part.com and look for
valid domains that come close to matching and add THOSE TO: fields to
the spam directory)
An even WORSE difference in behavior (plus you aren't notified that your
mail didn't make it to where you thought it was going)

Before the change if I email user(_at_)bogushost(_dot_)com, the email tool
would
tell me immedatally
that no such host exists.
Now, it unconditionally sends the email, then later bounces. This is a
HUGE difference
in behaviour.
