Execuse my ignorance ... what is a smarthost?

Its a host all non-local mail is sent to, which then handles onward
delivery, rather than attempting to deliver mail directly to the
recipient's mail server.

For example, my home setup is to use my ISP's smtp server as a
smarthost, so that I don't have to worry about the reliability of my
internet connection, problems caused by the reverse lookup of my IP
address (which I can't control) and servers which reject contacts from
addresses in dial-up pools.

smarthost is configured in sendmail.mc

define(`SMART_HOST',`yoursmarthost.yourdomain.co.uk')dnl

[then rebuild sendmail.cf]
