No, that's failing on the retry database. It is getting a failure when
calling fcntl() in order to lock the database. What DBM library are you
using? You might like to look at the long discussion about DBM libraries
in the file doc/dbm.discuss.txt.

[*] Set receiver_verify and arrange that such recipients fail verification,
for example by putting except_local_parts = abc on every director. Or
set up a director to match the recipients (by looking in an alias file,
for example), and set verify_only and fail_verify_recipient on it. Or...
(no doubt there are other ways).

Without using a filter, I'm not sure how to do that. [*] above works for
*all* incoming mail.

Likewise. Handling "inside" and "outside" isn't particularly easy. Some
sites do it by using a different port (i.e. not port 25) "inside" and so
they can run entirely different MTA configurations.
