This thread explains the problem pretty well:
http://www.irbs.net/internet/postfix/0309/2932.html
" ..the problem is that Yahoo is sending 8bitmime formatted email
(as Exchange announces 8bitmime support) but when Exchange forwards
that email on (in our case to a postfix server) it doesn't notice
that the remote server will accept 8bitmime formatted and so
refuses to deliver it.."
*surprise* .. Exchange is the system causing the problem in this case.
Hope this helps.
