I am pleased to announce the release of spamass-milt version 0.4.0.

This is the first of what I hope are a number of maintenance releases
with the goal to eliminate the outstanding bug/patch/feature requests:

The following changes are included in this release

- -C option to change the default reject code
- -S option to specify a path to sendmail (for the -x option)
- -R option to specify the rejection message
- -a option to skip messages that were authenticated
- IPv6 address support
- zombie process fix for the - option introduced in 0.3.2

This also includes the fix for CVE-2010-1132 that was in the unannounced but generated 0.3.2 release.
Updated mail/spamass-milter to 0.4.0
Remove patch-aa after update removed it from distinfo.
