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.
