Postfix 2.2 snapshot 20040919 available

New Postfix features are made available in Postfix 2.2 snapshot
releases. The stable 2.1 release does not change except for bugfixes
and in response to disasters.

Snapshot 20040919 catches up on Duchovni features and adds some
polish to session caching.

- Access control for local mail submission, for listing the queue
and for flushing the queue. These features are controlled with
authorized_submit_users, authorized_mailq_users, and with
authorized_flush_users, respectively. The last two controls are
always permitted for the super-user and for the mail system owner.
More information is in the postconf(5) manual. This code may change
behavior in the future.

- A new discard(8) mail delivery agent that makes throwing away
mail easier and more efficient. In case you wonder what this is
good for, it's the Postfix equivalent of /dev/null for mail that
is already in the queue. To delete mail while it is received, use
the DISCARD action in access maps or header/body checks. This
delivery agent is not going to change.

- The session cache daemon now logs statistics about the number of
destination and session cache entries, in addition to the hit rate
information that was already logged by previous versions. This
gives you a better idea of how many resources session caching is
consuming.
