    Do I understand you right, that you won't receive mail for your users?
    So why do you then run an MTA? That makes no sense, instead use the SMTP
    server of your ISP.

    If you really want to reject incoming mail for the local users - and
    that is not relaying what the SMTP does then! - create a
    /etc/mail/virtusertable with a catch all entry like

    @my.local.domain.tld ERROR:5.7.1:550 we do not accept incoming mail

    Run "make -C /etc/mail" afterwards. A restart of the Sendmail daemon is
    not necessary.
