Can I force auth in smtp session?

Hello friends,

At first, excuse my poor use of english language. I'm spanish.

I have been reading and using qmail and qmail-ldap during last year.
Recently I have done a new installation of qmail-ldap for replace my old
installation, based in the obsolete qmailrocks.

Well, my doubt at this moment:

Can I force my users to use AUTH login in an smtp session as jms patch
allow using REQUIRE_AUTH environment variable?.

See this for more info: http://qmail.jms1.net/scripts/jgreylist.shtml
(AUTH and greylisting section)

I want to run a smtp service on port 25 without relay, only for receive
incoming mail to my domain and other smtp service in port 465 wich require
AUTH login and TLS. I can use SMTPAUTH="TLSREQUIRED", but I want also that
auth login would be mandatory. With SMTPAUTH="TLSREQUIRED" I only get that
anybody can use relay without indetified, but any user can continue
sending mail to my domain without auth.
