Package: spamass-milter
Version: 0.3.0-1
Severity: minor
Tags: patch

Since loading spamass-milter, local users have complained that sending
mail takes too long (spamass-milter is checking all their e-mail).

The -i flag doesn't cut it, as we have road-warriors.

This patch adds a new -I flag, which, if added, will cause spamass-milter
to ignore any mail sent by authenticated senders.


PLEASE NOTE: While this patch has been tested, I have *NOT* confirmed
that it does not cause a small memory leak in spamass-milter.  I think
it may be possible, I do not fully grok the flow of calls yet.  Please
review.  I have also sent a copy of this patch on to Dan Nelson
upstream for review.
