Name
${daemon_family}
Synopsis
The sendmail program can listen for (await)
inbound connections on more than one interface, where each interface
can employ any one of five possible protocol families. Possible
families are inet
for AF_INET,
inet6
for AF_INET6, iso
for
AF_ISO, ns
for AF_NS, and x.25
for AF_CCITT. The value stored in this
${daemon_family}
macro is taken from the
DaemonPortOptions=Family
option (See this section) whenever a message is processed by rule sets,
and reflects the family of the interface upon which the inbound
connection was received.
This ${daemon_family}
macro is not used in the
rule sets supplied with sendmail. It is,
however, available for your use when designing custom rule sets. Note
that a $&
prefix is necessary when you
reference this macro in rules (that is, use
$&{daemon_family}
, not
${daemon_family}
).
${daemon_family}
is transient. If it is defined in
the configuration file or in the command line, that definition can be
ignored by sendmail.
