sendmail, mail is not getting delivered, getting an return mail


Hi

sendmail, mail is not getting delivered, getting an return mail

I have a system with Redhat AS 4 with latest update. And SELINUX is in worn mod

I have configured sendmail as (sendmail.cf entries are)


# my official domain name
# ... define this only if sendmail cannot automatically determine your domain
Djntcccbs.nationalphone.net

# host/domain names ending with a token in class P are canonical
CP.

# "Smart" relay host (may be null)
DS221.120.97.150

But every time I send a mail th /var/log/mailllog entries looks like as follows

May 2 09:17:34 ntcdrsrv sendmail[6572]: l423HTSa006572: from=root, size=47, class=0, nrcpts=1, msgid=<200705020317.l423HTSa006572@localhost.localdomain>, relay=root@localhost
May 2 09:17:36 ntcdrsrv sendmail[6573]: l423HYEi006573: from=<root@localhost.localdomain>, size=344, class=0, nrcpts=1, msgid=<200705020317.l423HTSa006572@localhost.localdomain>, proto=ESMTP, daemon=MTA, relay=ntcdrsrv [127.0.0.1]

May 2 09:17:56 ntcdrsrv sendmail[6575]: l423HYEi006573: l423HuEi006575: DSN: User unknown

Looks like your smart-host wants you to authenticate yourself, but you're not acknowledging that...
