Local user, but sendmail trying to relay, why?

A server in my lan, AK, is trying to send mail to my
desktop, DD, via its IP address: dale@[192.168.7.35].
"dale" is a local user on the desktop DD. However,
sendmail on DD is rejecting the mail with the message
"Relaying denied". Here are the relevant maillog messages,
wrapped for reading convenience:

Sep 2 23:11:21 DD sendmail[2591]: m834BKur002591:
ruleset=check_rcpt,
arg1=<dale@[192.168.7.35]>, relay=AK [192.168.7.201],
reject=550 5.7.1 <dale@[192.168.7.35]>... Relaying denied
Sep 2 23:11:21 DD sendmail[2591]: m834BKur002591:
from=<root@AK.EckhardtTrading.com>, size=582, class=0, nrcpts=0,
proto=ESMTP, daemon=MTA, relay=AK [192.168.7.201]

DD's sendmail config is a stock Fedora 8 config except
that I modified sendmail.mc to listen on the NIC that
connects DD to the lan, and opened port 25 on the firewall.

Why is sendmail on DD trying to relay for a local user?
Why doesn't it recognize that dale is a local user?
How can I debug this?

I appreciate any help you can give me.

I added the following line to /etc/mail/local-host-names, and now
it's working:
[192.168.7.35]

Apparently, sendmail didn't the IP address was local.

Normally sendmail gets IP addresses of interfaces.
But may be that there is some limitions. Try:

sendmail -d0.4 -bt < /dev/null

Sendmail should add it "auto-magically" unless:
a) it is a dynamic interface
(e.g. ppp dialup started after sendmail daemon statup)
b) DontProbeInterfaces is used in your /etc/mail/sendmail.cf file

No,

sendmail does _not_ get all IP addresses on Linux.

Specially, if there is several ip addresses on one interface,
sendmail does not get them all.

Look "ip addr" command.

Basically sendmail gets only addresses, which "ifconfig"
-command is listing.
