Sendmail, a question on Forwarding host

[dale chayes]

I have discovered that occasionaly my local sendmail configuration is
causing problems at my "forwarding host" by creating an odd address.
So I poked around with sendmail -v and observed a bit of (what seems
to me to be) strange behavior shown in the example below.

hp8c is an unknown host, 
lamont is my "forwarding host"  from the DF & CF macros in sendmail.cf

I'm using the standard 3.3.1 versions with the additions as explained
at the top of sendmail.cf.  I'm sure no M4/Sendmail whiz, and I was
hoping that someone could point out what's wrong here.

I would expect that the constructed address should look like:

dan%hp8c.nrl.navy.mil at lamont.ldgo.columbia.edu

but instead, it creates the address pointed out below.

gonzo:/usr/people/dale> /usr/lib/sendmail -v dan at hp8c.nrl.navy.mil
Subject: YAT
The is a test, throw it out!
