Redirecting incoming mail to blackhole

SebastianG
Is it possible to redirect incoming eMail with a specific destination adress, which normally is forwarded to an Exchange server in our network, to a blackhole? This adress is no longer used here, but by spammers...

    hm,
    i have the incoming mail being processed by asl,
    given to a mailserver with sendmail.
    there i have an alias-file /etc/mail/aliases
    and in this i defined:
    legal_user_a: legal_user_a@localhost
    legal_user_b: legal_user_b@127.0.0.1
    ...
    spam_user_a: /dev/null
    spam_user_b: /dev/null

    think exim (used in asl)  should have some configuration-file also?

    but would be a nice field in the webinterface [;)]

    kind regards, christian

    Won't exchange just reject the message since the user no longer exisits ?

    I'm not completely sure, but I think you are right Simon. At least, I get an entry in the event log and an error message into my Outlook-inbox.
    But in my opinion, it would be nice if Exchange would have got nothing to do with these mails. I think, I will have a look into the Exim-docs. Perhaps there is a possibility like Christian's.

    Greetings

    Hi Chris,

    I just found something in the exim-users-list [Exim] \dev\null. The problem now is, that I am not completely sure, what to do. Perhaps I can get a little help? 

    Thx.

    You could always turn on recipient verification which would recognize that user is no longer there on the mailserver and then take action based on that however this generates a bounce with "user unknown" not a blackhole.

    not sure if that helps or not.
