[Mimedefang] Using a db for subject lines to block

[Kevin A. McGrail]

Ken:

Why the switch from your sendmail rules (i.e.  /etc/mail/subjects_full and 
/etc/mail/subjects_part)  to MD to check the subject?  I would think 
avoiding a milter call for memory and processor savings would be beneficial.
