RE: Mail not sending

["Geoff Rainey (DSLAK)" <GeoffR datacom co nz>]

I do not know if this issue has been answered yet, but is this not
a sendmail.cf configuration parameter to send mail directly to a 
relay and not the localhost?

The parameter I am reffering to is

Smart relay host, here is an example from the sendmail.cf file -

----------------------------------
# "Smart" relay host (may be null)
DSakmscet55.nzpost.co.nz
----------------------------------

Where akmscet55.nzpost.co.nz is the mail server.

regards,
Geoff.
