** All mail arriving at debbugs.gnu.org is first run through SpamAssassin.
Obvious spam is rejected, the rest is sent on to the moderated list
debbugs-submit. Approved mail is passed on to the tracker.
+(Note this means that messages may appear out of sequence in the
+tracker, since mail from whitelisted senders goes straight through.)
NOTE: An alternative to this would be to use listhelper AT nongnu.org
as a moderator address. Eg the emacs-bug-tracker list uses this.
