${cert_issuer}
Distinguished name of certificate issuer V8.11 and later
As a part of the STARTTLS form of authentication and
encryption, certificates are usually exchanged. The
certificate presented by the other side is signed by
a certificate authority, and this ${cert_issuer} macro is
assigned the distinguished name (the DN) of that
certificate authority. That value might look like
this:
/C=US/ST=California/L=Berkeley/O=Sendmail.org/CN=Sendmail+20CA/
See The access database and
Local_Relay_Auth
on page 213 for an illustration of one use for
${cert_issuer}.
See Macro Xtext Translations on
page 795 to find how and why the value in this macro
undergoes special translation.
${cert_issuer} is
transient. If defined in the configuration file or
in the command line, that definition can be ignored
by sendmail. Note that a
$& prefix
is necessary when you reference this macro in rules
(that is, use $&{cert_issuer}, not ${cert_issuer}).
