${daemon_name}
Listening daemon’s name V8.10 and later
The ${daemon_name}
macro contains the value of the DaemonPortOptions=Name
option (DaemonPortOptions=Name=
on page 996) whenever an inbound connection is
accepted. The names assigned in the default
configuration file are MTA (for the daemon that
listens on port 25) and MSA (for the MSP daemon that
listens on port 587).
As distributed, this ${daemon_name} 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_name}, not
${daemon_name}).
${daemon_name} is
transient. If it is defined in the configuration
file or in the command line, that definition can be
ignored by sendmail.
