[SunHELP] Mail sent but not received

[Marek Grinberg]

Hello,

In a Sun E250 running Solaris 5.6, I create a mail, and it apperas as 
being sent, but I do not receive it:
# mail root
text
.
# mailq
Mail queue is empty
# mail
No mail.
# mailx root
Subject: text
lll
.
EOT
# mail
No mail.
# mailq
Mail queue is empty
#

/etc/mail/sendmail.cf contains:
 # "Smart" relay host (may be null)
 #DSmailhost.$m
 DSmail.x.com
 ...
 DRmail.x.com

/var/log/syslog contains:
May 10 15:49:30 neat-test sendmail[670]: PAA00670: from=neat, size=80, 
class=0, pri=30080, nrcpts=1, 
msgid=<200605101349.PAA00670 at neat-test.x.com>, relay=root at localhost
May 10 15:49:32 neat-test sendmail[672]: PAA00670: to=root, ctladdr=neat 
(1003/10), delay=00:00:02, xdelay=00:00:02, mailer=relay, 
relay=mail.x.com [a.b.c.d], stat=Sent (sehan022as.x.com: Message 
accepted for delivery)

Apparently the mail is sent, but to external SMTP (mail.x.com). Should 
mail to internal user (root) go directly to this user, and not via the 
SMTP (mail.x.com) ?
