${cn_issuer}
Common name of certificate signer 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 must be
authorized by a certificate authority (CA). When it
is, this ${cn_issuer}
macro is assigned the
common name (CN) of the CA that signed that
certificate. That value might look like this:
Tan+20Woo ← a person's name Woo+20Poultry ← a business name
See Macro Xtext Translations on page 795 to find how and why the value in this macro undergoes special translation.
${cn_issuer}
is
transient. If it is defined in the configuration
file or in the command line, that definition can be
ignored by sendmail. Also note
that a $&
prefix is necessary when you reference this macro in
rules (that is, use $&{cn_issuer}
, not ${cn_issuer}
).
