Exactly!

It is actually a little confusing.  You virtually never wanto to set
AUTH_REQUIRED to 1.  What we (the common folk) usually mean by esmtp
authentication is the authentcation by the client mail program to send
mail.

What AUTH_REQUIRED variable sets is whether or not all mail that comes
to your server has to authenticate.  If you set it to 1, all of your
mail will bounce barring setting up a "smart" gateway as mentioned in
the original message.

To set up client authentication, you set:

AUTHMODULES="authdaemon"
ESMTPAUTH="LOGIN"

(you can include cram-md5 next to login, but i didn't get that one to
work)

And it's true -- the default is --
AUTHMODULES=""
ESMTPAUTH=""

no auth by default.

Cheers!
