994 | Chapter 24: The O (Options) Configuration Command
Only the first character in each key is recognized, so a succinct declaration suchas the
following can be used to change the port used by the daemon:
O DaemonPortOptions=P=26,A=our-addr # Only listen for local mail on nonstandard port
26
The DaemonPortOptions option is not safe. If specified from the command line, it can cause
sendmail to relinquish its special privileges.
24.9.27.1 DaemonPortOptions=Addr=
The Addr key specifies the address to use. The value is the name* or IP address of one of
your network interfaces:
O DaemonPortOptions=Addr=128.32.204.25 # listen to our IP address only
If the Addr= and its value are omitted, the default address becomes INADDR_ANY, which
allows connections to any address on the local machine. Note that this Addr is most useful
on multihomed (or multialiased interface) machines, although it can also be useful on
single interface machines (such as listening for connections on the localhost, 127.0.0.1).
Whenever sendmail calls rule sets to process a message, it puts the value of this
DaemonPortOptions=Addr option into the ${daemon_addr} macro (?§21.
