sendmail X is a modularized message transfer system consisting of five
|
|
(or more) persistent processes, four of which are multi-threaded. A central
|
|
queue manager controls SMTP servers and SMTP clients to receive and send
|
|
e-mails, an address resolver provides lookups in various maps including DNS
|
|
for mail routing, and a main control program starts the others 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.
|
|
|
|
sendmail X.0 is intended to be used as a secure and efficient mail gateway. It
|
|
does not provide any mail content modification capabilities, e.g., address
|
|
masquerading.
