MeTA1 is a message transfer agent that has been designed with
|
||
|
|
these main topics in minds:
|
||
|
|
|
||
|
|
* Security
|
||
|
|
* Reliability
|
||
|
|
* Efficiency
|
||
|
|
* Configurability
|
||
|
|
* Extendibility
|
||
|
|
|
||
|
|
MeTA1 consists of five main modules of which only one runs as root:
|
||
|
|
|
||
|
|
* mcp: the main control program is similar to inetd(8):
|
||
|
|
it starts all other MeTA1 modules and watches over their execution.
|
||
|
|
mcp runs as root in order to bind to port 25 and to change the uid
|
||
|
|
of the processes it starts.
|
||
|
|
* smtps: the SMTP server receives e-mails.
|
||
|
|
* smtpc: the SMTP client sends e-mails.
|
||
|
|
* smar: the address resolver provides lookups in various maps
|
||
|
|
including DNS for mail routing.
|
||
|
|
* qmgr: the queue manager controls the flow of e-mails through the
|
||
|
|
SMTP servers and clients.
