Name
${opMode}
Synopsis
Beginning with V8.7, the
${opMode} holds as its value the operating mode
that sendmail was started with. The operating
mode is set with the -b command-line switch (-b). For example, if
sendmail were started as a daemon with
-bd, the value in ${opMode}
would become d.[20]
Once set, ${opMode} retains its initial value as
long as sendmail runs. It can be changed only by
defining it in the configuration file (not recommended). Currently,
${opMode} is used only in rule sets by the
redirect feature (FEATURE(redirect)).
Because ${opMode} generally does not change once
it is defined, you need not prefix it with $&
when using it in rules.
[20] Because the LHS of
rules are case-insensitive, you cannot use just this macro to detect
the difference between -bd and
-bD.
