24.9.27.11 DaemonPortOptions=ReceiveBufSize=
The ReceiveBufSize key is used to specify the size of the TCP/IP receive buffer. The value is
a size in bytes. This should not be set unless you are having performance problems. Slow
links (such as 9.6K SL/IP lines) might profit from a setting of 256, for example:
O DaemonPortOptions=ReceiveBufSize=256
The default value is set by the system (see setsockopt(2)).
24.9.27.12 DaemonPortOptions=refuseLA= (8.14 and later)
The refuseLA key is used to specify a load average at which sendmail will begin to refuse
acceptance of all inbound connections. This setting overrides the setting for the RefuseLA
option (?§24.9.96 on page 1078). See also the DaemonPortOptions option??™s delayLA
(?§24.9.27.3 on page 995) and queueLA (?§24.9.27.10 on page 997) keys.
