Odd sendmail behavior change

[Randy Pratt]

Sendmail seems to have changed its behavior in the last week.  I only
use sendmail for system mail and it was working up until May 28:

 May 28 03:08:23 kt sendmail[96390]: k4S78MdC096390: to=root,
 ctladdr=root (0/0), delay=00:00:01, xdelay=00:00:01, mailer=relay,
 pri=32393, relay=[127.0.0.1] [12 7.0.0.1], dsn=2.0.0, stat=Sent
 (k4S78MRA096392 Message accepted for delivery)

 May 28 03:09:39 kt sm-mta [96399]: k4S78MRA096392:
 to=<root at kt.weeble.com>, delay =00:01:16, xdelay=00:01:16,
 mailer=esmtp, pri=32709, relay=hus.parkingspa.com. [ 66.246.195.41],
 dsn=4.0.0, stat=Deferred: Operation timed out with hus.parkingspa.com.

Now all system mail seems to want to be forwarded thru some relay
at hus.parkingspa.com.  I have no clue where this came from nor
can I find any configuration for it.  My sendmail configuration
has always been the default (6.1-STABLE).  The only 'configuration'
I've done is to alias root's mail to my local user in /etc/aliases.

Have there been any changes to sendmail or required configurations
that I've missed.  src/UPDATING gave no clues and I've grepped files
trying to find where "hus.parkingspa.com" could have came from to
no avail.

Any suggestions for fixing this would be appreciated.  If any 
information is needed, just ask.
