I use this:
smtp_url="smtp://localhost/"
(I run sendmail locally. I could use local submission via $sendmail,
but I use the built-in SMTP code to exercise the code.)
I also have certain send2-hooks which replace that with another SMTP
server. You can replace localhost with your smtp server name, and
submit without authn.
