${daemon_port}
Listening daemon’s port V8.10 and later
The ${daemon_port}
macro contains the value of the DaemonPortOptions=Port
option (DaemonPortOptions=Port=
on page 997) whenever mail is processed by the
daemon listening on that port.
As distributed, this ${daemon_port} macro is not used in the
configuration file. It is, however, available to you
for use in designing your own particular rule sets.
Note that a $& prefix is necessary when you
reference this macro in rules (that is, use $&{daemon_port}, not
${daemon_port}).
${daemon_port} is
transient. If it is defined in the configuration
file or in the command line, that definition can be
ignored by sendmail.
