24.9.23 ConnectionRateWindowSize
Window of time in which to measure connection rates V8.13 and later
Under V8.13, two new sendmail macros, called ${client_rate} (?§21.9.24 on page 814) and
${total_rate} (?§21.9.95 on page 847), are available to control the number of simultaneous
connections allowed. They are used by the corresponding new FEATURE(ratecontrol)
(?§17.8.13 on page 619) and FEATURE(conncontrol) (?§17.8.43 on page 638), which perform
the same functions via the access database.
This new ConnectionRateWindowSize option sets the size of the window of time that is
used to measure these rates. It is declared like this:
O ConnectionRateWindowSize = secs ?†? configuration file (V8.13 and later)
-O ConnectionRateWindowSize = secs ?†? command line (V8.13 and later)
define(`confCONNECTION_RATE_WINDOW_SIZE??, `secs??) ?†? mc configuration (V8.13 and later)
Here, secs is of type time. If this option is omitted, the default for the window of time is 60
seconds. If this option is defined, but the time units are omitted, the default units are
seconds.
We recommend you change the default only if you have not already made connectionlimiting
entries in your access database. If you make those entries first, and then later
change this setting, you will silently change the meaning of those access database entries.
The ConnectionRateWindowSize option is not safe.
