- - Improve resilience to malformed email addresses

+ - Improve support for non-ASCII email messages.  Anything UTF-8 should work
+   (including correct signing/verification).  For messages that contain header

+ - Set minimum pymilter and dkimpy versions in setup.py to those that will
+   work reliably with non-ASCII content.

 rsa-sha1 signatures as valid for verification because they are still in
 common use and are not known to be cryptographically broken.
