Hi,

I have two freebsd mail servers both configured SMTP authentication:

    FreeBSD Handbook 28.10 SMTP Authenticatin
    http://www.freebsd.org/doc/en/books/handbook/smtp-auth.html

    SMTP AUTO in sendmail 8.10-8.13
    http://www.sendmail.org/~ca/email/auth.html

One is functional, and the other one doesn't seem to work. Compare the 
maillogs of the two servers, there is an AUTH=server message appear in the 
functional server, but the other one has not.

The maillog of functional server
======================
Jul 29 16:15:10 maple sm-mta[57825]: AUTH=server, relay=59-....net 
[59...147], authid=a660407, mech=LOGIN, bits=0
Jul 29 16:15:10 maple sm-mta[57825]: n6T8F9ej057825: from=<reedlai@...>, 
size=1430, class=0, nrcpts=1, 
msgid=<40F9CC65E8874D128639A39C1EEBD410@ReedXP>, proto=ESMTP, daemon=IPv4, 
relay=59-...net [59...147]

The other one
=========
Jul 29 17:12:41 banyan sm-mta[2539]: n6T9Cf9q002539: ruleset=check_rcpt, 
arg1=<reedlai@...>, relay=59-...-147.HINET-IP.hinet.net [59...147], 
reject=550 5.7.1 <reedlai@...>... Relaying denied
Jul 29 17:12:41 banyan sm-mta[2539]: n6T9Cf9q002539: from=<reedlai@...>, 
size=0, class=0, nrcpts=0, proto=ESMTP, daemon=IPv4, 
relay=59-...-147.HINET-IP.hinet.net [59...147]

It seems the other one's smtp authentication is not trigged.

Please help or tip me for something I forget.

Thank you!

Reed
