That's a SpamAssassin header, added by the server. Your mail provider 
put that message in Junk, not MailMate. The total score of 7.2 is 
significantly above the default SA threshold score for spam (5.0) but 
the 'X-Spam-hits' itemization shows that almost entirely due to one 
issue: the "URIBL_DBL_ABUSE_SPAM" hit scored at 7. That hit indicates 
that there was a link in the message body whose domain is listed in the 
Spamhaus DBL list: https://www.spamhaus.org/dbl. It is rare for the DBL 
to list domains that are not exclusively used in spam, but it does 
happen.
