''${cert_issuer}'' '''


Distinguished name of certificate issuer V8.11 and above

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:


See Section for an illustration of one use for ${cert_issuer}. See Section 21.6.2 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}).
