I'm still not there. I'm using sendmail-8.12.10 (the latest).

If I have a SMART-HOST entry then all mail to the outside world goes to
the ISP's mail machine without requiring a passwd (which is what I
wanted). But a side effect is that all mail between machines on my home
network (ie that aren't supposed to leave the home network) are also sent
to the SMART-HOST (the specs for SMART-HOST say that _all_ mail will be
relayed to the SMART-HOST).

I want mail to be sent to the same places as my routing tables, ie mail to
foo.home.net gets sent to machine foo on my home network, while mail to
bar.outside_domain.net gets sent to my mail gw (SMART-HOST).

I've looked at ./cf/README for all the commands to put into your
sendmail.mc file and although I don't understand it much, there doesn't
seem to be any obvious solution.

Does anyone know how to set up mail so that one mailserver on the home
network will distribute all internal mail internally, and only send mail
for outside machines to SMART-HOST? This doesn't have to be sendmail. I'm
happy to use post-fix etc

Thanks Joe
