Found this 'answer' via Google:

"It appears that remote end just didn't politely end its connection, 
or was disconnected, or had connectivity problems after it completely 
sent its message."

I'm guessing that the USDA's mail server (or wherever these messages 
are actually coming from) isn't behaving 'nicely'... but I don't 
think it's anything to worry about (aside from your process/load 
issue).

See if you can get in touch with 'postmaster@xxxxxxxxxxxxxx' and let 
them know... if they're messing with your server, they're probably 
messing with lots of others too, and don't even know...

(As an interesting aside, I tried telnetting to port 25 on the IP 
address listed, but nothing 'answers'... so if it _is_ a mail server, 
something is definitely 'unusual' about it...)
