+ Bugfix: 20021207 (move relocated table lookup from queue
+ manager to trivial-rewrite server) broke relocated table
+ lookup results with mail not rejected at the SMTP port.
+ Files: *qmgr/qmgr_deliver.c, *qmgr/qmgr_message.c.
+
+20030123
+
+ Bugfix: a widely used maildir filename algorithm was broken.
+ Postfix now uses TIME.DEVICE_INODE.HOST. Files: local/maildir.c,
+ virtual/maildir.c.
+
Open problems:
Med: make qmgr recipient bounce/defer activity asynchronous
because a lot of main.cf like information gets listed in the
master.cf file. This makes the system hard to understand.
+Even worse, details change as Postfix evolves and different
+configuration parameters are implemented by different programs.
+
If you need to squeeze out more performance, it is probably simpler
to run multiple Postfix instances, one before and one after the
content filter. That way, each instance can have simple main.cf
SMTP mail via localhost port 10025, and that submits SMTP mail back
into Postfix via localhost port 10026.
