Chapter 4. Configure sendmail.cf with m4

In the cf subdirectory of the V8 sendmail source distribution, you will find the file README. It contains easy-to-understand, step-by-step instructions that will allow you to create a custom configuration file for your site. This chapter supplements that file.

What’s New with V8.13

  • The new confREJECT_LOG_INTERVAL mc macro (Section 4.1.1 [V8.13]) sets the new RejectLogInterval option (Section 24.1.11 [V8.13]). It specifies how often a message advising that connections are still being refused should be logged.

  • The new confCONNECTION_RATE_WINDOW_SIZE mc macro (Section 4.1.3 [V8.13]) sets the new ConnectionRateWindowSize option (Section 24.1.13 [V8.13]). It defines the window of time over which a count of the number of connections is maintained in order to enable connection rate-control.

  • The new confTO_QUEUEWARN_DSN mc ...
