Overview

Sendmail is an electronic mail transfer agent (MTA) that sends and receives mail messages to and from homogeneous and heterogeneous networks. Sendmail sends a message to one or more recipients or addresses, routing the message over appropriate networks. Starting with Sendmail 8.13.3, Sendmail can also be used as a mail submission program (MSP).

When Sendmail acts as an MTA, it listens on port 25 and is primarily concerned with routing mail from other mail servers. Simultaneously, Sendmail can also accept mail messages from local users, thereby acting as a MSA. Sendmail 8.11.1 introduced the conceptual separation of these two roles, while Sendmail 8.13.3 handles these roles independently by default. When operating as an MSA, Sendmail 8.13.3 listens on port 587 instead of port 25. Sendmail 8.13.3 accepts a mail message from an Mail User Agent (MUA), parses the mail message, and forwards the mail message through Simple Mail Transfer Protocol (SMTP), to Sendmail 8.13.3 that is running as an MTA. Sendmail 8.13.3 is by default a set-uid program. For better security, you can run Sendmail 8.13.3 as a set-gid program. For more information on configuring Sendmail 8.13.3 as a set-gid program, refer to the "Sendmail 8.13.3 Release Notes" document available at HP Support Center. Table 1 summarizes the Web upgrade version of Sendmail available on the HP-UX 11i v1, HP-UX 11i v2, and HP-UX 11i v3 operating systems.

b The Sendmail releases B.11.11.02.002 and B.11.23.1.002 were intermediate releases. You may not find these release names mentioned in any documentation available with B.11.11.02.003 and B.11.23.1.003 because B.11.11.02.002 and B.11.23.1.002 did not provide a complete solution.


NOTE: HP recommends that you remove any unofficial (UNOF) Sendmail patch before installing this version of Sendmail 8.13.3 Web upgrade on an HP-UX 11i v1, HP-UX 11i v2, or HP-UX 11i v3 operating system.
