[olug] UNICODE smtp woes

Hello all,
I've got a sendmail system (sendmail-8.11.6-3 RedHat package) that sends 
out emails to many of our clients. Most of these go through without a 
hitch, but lately I've been seeing some errors. This is text from the 
message that I get back (I'm the From: address, so errors go to me):

This is an automatically generated Delivery Status Notification.
Delivery to the following recipients failed.
       slove+AEA-oppd.com

Then it goes on to show the message, which says "slove at oppd.com" in the 
To: line. Also, /var/log/maillog on the server always shows the "@" 
symbol, and never the "+AEA-" symbol. I've researched this enough to know 
that it's a unicode issue, but I can't seem to track it down. It seems to 
only happen when I email certain domains. Anyone seen this before? Is it 
something in my sendmail config that I need to add? Like I said, this 
affects maybe 2% of the emails this box sends out, but with some domains I 
get this everytime I try to email them.

TIA
