(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.
