MS unable to detect From address from DSN and failure notice emails

[Mike Jakubik]

The other day i noticed that Always looked up last and the mailwatch 
logging script is not logging the From address on any DSN or failure 
type emails sent by the mailer-daemon@ or postmaster at . The problem is 
bigger than just logging itself, as this influences the scoring with the 
rule NO_REAL_NAME, so a lot of them get marked as spam. Here are two 
example headers:

This got marked as spam, and the From field is never logged. Any ideas?
