You can enable the `blacklist_recipients' feature, by adding this to
your sendmail.mc file:

    FEATURE(`access_db', `hash -T<TMPF> -o /etc/mail/access')
    FEATURE(`blacklist_recipients')

Then, adding entries like this to /etc/mail/access and rebuilding the
access.db map will block email for the particular address:

    To:user at host.domain		REJECT

or even the more descriptive:

    To:user at host.domain		ERROR:550 Mailbox disabled for this recipient

If you need more help for making the `access.db' map work and updating
the configuration files in `/etc/mail', feel free to ask.
