sendmail X is a message transfer system that has been designed with
|
|
these main topics in minds:
|
|
|
|
- security
|
|
- reliability
|
|
- efficiency
|
|
- configurability
|
|
- extendibility
|
|
|
|
sendmail X 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 sendmail X 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.
