I disagree. Accepting mail without verifying the recipient is idiocy,
given the realities of the internet.

If you have no other choice, then I suggest that you configure a
catch-all address on your courier system, and discard mail that's sent
to it. A ".courier-default" file with one blank line should work.

It probably doesn't. It does, however, tarpit servers that send bad
commands, including directing mail to non-existent users.

If your virus scanner batches mail (and it probably does), legitimate
mail is going to be delayed because of the bad mail. The remote server
might be just giving up and disconnecting.

It's doing what it was designed to do. It's not courier's fault that
you haven't considered the consequences of mixing two technologies that
weren't designed to work together. You have options to fix the problem,
though.

....and please keep replies on the list. :)
