Thanks for that. That is really helpful. OK, so that brings me to my
next question:

Why does Claws think some of these emails are spam ? 

I don't have any of the spam or anti-virus plugins enabled.

I can't see anything in the email headers which would indicate SPAM and
most of the messages flagged are legitimate. On what information is
Claws making this assessment ?

Cheers
