sendmail, 4th Edition

${daemon_info}

---

Listening daemon's syslog information

V8.10 and above

Whenever sendmail starts running as a daemon, it places the same information that it logs into this ${daemon_info} macro. For example, the following syslog information:

 starting daemon (8.10.1): SMTP+queueing@01:00:00 

would cause the value of ${daemon_info} to become:

 SMTP+queueing@01:00:00 

As distributed, this ${daemon_info} 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_info} , not ${daemon_info} ).

${daemon_info} is transient. If it is defined in the configuration file or in the command line, that definition can be ignored by sendmail .
