Getting a lot of 'Postmaster' returned emails...

[Leonard Hermens]

Hi,

As a follow-up question to this one. What is the current best practice for
rejecting invalid addresses? To you send them to /dev/null or something
more clever than that?

We purposely accept all inbound email so as to not show valid/invalid
addresses to spammers on attempted sends (to avoid harvesting). A second
server scans for content and validates the addresses.

Comments and tricks are appreciated.
