Hello Randy,

From the FAQ, I think Q9807 is a better approach to get a solution. Of course there
could be another way ;-)

<cut>
Q9807: I have someuser@??? that I only want certain users to be able to mail to.
How do I accomplish this?

A9807: This is a transport:

bounce:
           driver  = autoreply
           from    = postmaster@???
           to      = $sender_address
           user    = exim
           subject = "Re: Your mail to ${local_part}"
           text    = "You are not allowed to mail to ${local_part}."


This is a director that should come before all the others:

special_user:
           driver = smartuser
           local_parts = someuser
           transport = bounce
           senders = !: !lsearch;/list/of/permitted/senders


Note that leading "!:" in senders. It allows the null sender <> to be valid
(i.e. not to match this director). This is necessary, since bounce messages
have null senders. All other permitted senders must be in the file as complete
addresses, including a domain.
</cut>


I did not think deeply about this but I've a feeling that since the response
is to spammers, there may be no need for one. So maybe in the transport you
can use an alias address in the from = nerds@???, where in the aliases
file you have

nerds:        /dev/null



because you don't want spammers replying to you, yes?
