When I want to bounce a message for <jdoe(_at_)(_dot_)(_dot_)(_dot_)>, I

has neither an A nor an MX record for EXAMPLE.COM, my local
immediately MTA bounces it back as undeliverable. The text of the
bounce-o-gram varies depending on how I do this (sometimes it says the
original address failed, sometimes it says "jdoe(_at_)example(_dot_)com"
failed),
but it's a legit MTA-produced bounce in any case.
This is kind of outside the scope of the procmail list, but...
This is something that usually has a better tool in the MTA. There are at
least two ways of handling this in Sendmail (I won't address other MTAs, as
I'm not familiar with them): FEATURE blacklist_recipients, and FEATURE
virtusertable. The former allows you to define local addresses, hostnames or
usernames that are blocked in the access database. With the later, you simply
define an alias in the virtusertable thus:
blocked(_at_)domain(_dot_)tld error:nouser Some Text Here
Or any other valid SMTP error condition.
This, to my mind, is much more "correct" than the kludge defining an alias for
an address, that points to another non-deliverable address.
