    This means that your server will now relay mail for the domain of your
    ISP (e.g. as if your server was a backup MX for the ISP). It's not an
    open relay (your server can't be abused to send mail *anywhere*) but
    it's not the "right" solution. All you should have needed was an entry
    for your local network in the /etc/mail/access file:

    192.168.0 RELAY

    This would configure your server to relay mail for your LAN clients
    192.168.0.*.

    Did you run "make" in the /etc/mail directory after editing the access
    file? This rebuilds the access.db file, which is the one actually used
    by sendmail. If you forgot to do that, your changes wouldn't have
    appeared to have had any effect.

    Cheers, Paul.
