MeTA1 is a modularized message transfer agent (MTA)
consisting of five (or more) persistent processes,
four of which are multi-threaded. A queue manager
controls SMTP servers and SMTP clients to receive
and send email messages, an address resolver
provides lookups in various maps (including DNS)
for mail routing, and a main control program
starts the other processes and watches over their
execution. The queue manager organizes the flow of
messages through the system and provides measures
to avoid overloading the local or remote systems
by implementing a central control instance. It is
simple to configure using a C-like syntax and is
secure and efficient.
Release Notes: This release enables basic DH support for STARTTLS in the SMTP server and modifies the behavior of the scheduler if a limit for outgoing connections is reached.
