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.
