What is the error message? And what has been logged before & after it, 
because this info is related probably?
What does "outward" mean: originating from localhost via sendmail binary 
or via SMTP?

The sample code in the man page includes a default return value. I'm not 
certain, whether or not that is required, but I would add it.

This test is quite "open", although it is less likely for false hits. I 
would use a strong test e.g. lc($type) eq 'text/html' or anchor the 
beginning of the pattern.
