Hi people, can someone help me here.

I have exchange running on SBS with a pop connector which we use to exchange
mail between our domain provider and ourselves. We have now an external IP
address which is NAT'ed to the server and have tested succesfully that we
can put emails into the server by telneting.

So, I need to get the ISP to change the MX records so people can email us
directly, no problem there. However, Im not sure what we do regarding
outgoing mail. How do I setup exchange to send outgoing emails via SMTP
directly to the hosts.

Regards

It's doing that now, by default, unless you specified that you wanted the
virtual SMTP server to forward outbound Internet mail to a smarthost (such
as your ISP's SMTP server). By default, it sends out mail directly, doing
DNS lookups to find the MX records for the recipient domains.
