Parse the Authentication-Results header and display it in the message viewer (not enabled by default). DKIM, SPF and DMARC authentication methods are supported. Implement recommendation from RFC 7601 Sec 7.1 to have an explicit list of trustworthy hostnames before displaying the authentication results. Be aware that the authentication headers can be forged. To display the results for a specific authentication method, add the corresponding name to the layout of headers in the viewer section of aerc.conf, e.g. to display all three, use: header-layout = From|To,Cc|Bcc,Date,Subject,DKIM|SPF|DMARC More information will be displayed when "+" is appended to the authentication method name, e.g. DKIM+ or SPF+ or DMARC+. Also, add the trustworthy hosts per account with the trusted-authres parameter, e.g. trusted-authres = * to trust every host or use regular expressions for a finer control. Multiple hosts can be entered as a comma-separated list. Authentication results will only be displayed when the host is listed in the trusted-authres list.
