Do you mean, feature to detect that hotmiel.com is a typo?
Do you mean, feature to drop mail immediately when hotmiel.com
accepts no SMTP connection? What about other domains with
delivery errors?

i means reduce the queue life time per outgoing connection error.
For example, Postfix detect a "Connection refused" and reduce queue life
time to 6 hours instead 5 days for this error.
But for a "timed out" it keep 5 days.
Unfortunately, the behavior of intentionally dead domains eg.
hotmiel.com is indistinguishable from legit domains
experiencing a temporary outage.
From the external standpoint, there is no significant
difference between a connection refused and a timeout. They
are both temporary errors.
Your choices are:
- add transport entries for common misspellings to immediately
bounce the message.
- reduce the max queue lifetime for all deferred mail
- just live with it. It shouldn't be enough mail to affect
postfix operation.
