A queue managercontrols SMTP servers and SMTP clients to receiveand send email messages, an address resolverprovides lookups in various maps (including DNS)for mail routing, and a main control programstarts the other processes and watches over theirexecution. The queue manager organizes the flow ofmessages through the system and provides measuresto avoid overloading the local or remote systemsby implementing a central control instance.

Changes:
This release fixes a few bugs, most of which arerelated to createmap and the cdb map type. Two newfeatures were added. The interesting one is thatthe SMTP server now treats "Relaying denied"errors as "bad" commands. This means that thoserejections count for max_bad_commands_per_sessionand max_bad_commands_per_transaction. This isuseful when a client is broken enough to tryseveral relaying attempts.
