Please can you send me an example message? Try to extract the raw queue 
files (use the Quarantine or Archive Mail options to store a copy of 
it), then zip those up and send them to me at 
mailscanner at If you can't email them to me, then use to send them to me (that's a ZendTo site, 
my other project, which you may also be interested in!).

Then I can take a look.
