.cindex headers "authentication-results:"
.cindex authentication "expansion item"
This item returns a string suitable for insertion as an
-&'Authentication-Results"'&
+&'Authentication-Results:'&
header line.
The given <&'authserv-id'&> is included in the result; typically this
will be a domain name identifying the system performing the authentications.
The value of this option is expanded and indicates the source of DH parameters
to be used by Exim.

+This option is ignored for GnuTLS version 3.6.0 and later.
+The library manages parameter negotiation internally.

+&*Note: The Exim Maintainers strongly recommend,
+for other TLS library versions,
+using a filename with site-generated
local DH parameters*&, which has been supported across all versions of Exim. The
other specific constants available are a fallback so that even when
"unconfigured", Exim can offer Perfect Forward Secrecy in older ciphersuites in TLS.
Usable for GnuTLS 3.4.4 or 3.3.17 or OpenSSL 1.1.0 (or later).
-For GnuTLS 3.5.6 or later the expanded value of this option can be a list

+For OpenSSL 1.1.0 or later, and
+.wen
+for GnuTLS 3.5.6 or later the expanded value of this option can be a list
of files, to match a list given for the &%tls_certificate%& option.
The ordering of the two lists must match.
-The file(s) should be in DER format
+.new
+The file(s) should be in DER format,
+except for GnuTLS 3.6.3 or later when an optional filetype prefix
+can be used. The prefix must be one of "DER" or "PEM", followed by
+a single space. If one is used it sets the format for subsequent
+files in the list; the initial format is DER.
+When a PEM format file is used it may contain multiple proofs,
+for multiple certificate chain element proofs under TLS1.3.

The current list of events is:

&`dane:fail after transport `& per connection

The :defer events populate one extra variable: &$event_defer_errno$&.
