Set up smart relay host for outgoing smtp

[will2k]

I need to set up a smart relay host for all my mail to forward to going out through smtp - can anyone tell me where to set this on my postfix box (running FreeBSD)

Cheers!!

I got this from the postfix site

http://www.postfix.org/rewrite.html

and

http://www.postfix.org/transport.5.html

Transport table lookups are disabled by default. To enable, edit the transport_maps parameter in the main.cf file and specify one or more lookup tables, separated by whitespace or commas. For example:

transport_maps = hash:/etc/postfix/transport

Update your transport file as described below and then run the postmap command against it.

postmap /etc/postfix/transport

In order to deliver internal mail directly, while using a mail relay for all other mail, specify a null entry for internal destinations (do not change the delivery transport or the nexthop information) and specify a wildcard for all other destinations.

my.domain :
.my.domain :
* smtputbound-relay.my.domain

I have not verified that this works, but the documentation is there. Hope this helps.
