NAME

Mail::DMARC::Report::Send::SMTP - utility methods for sending reports via SMTP

VERSION

version 1.20240314

SUBJECT FIELD

The RFC5322.Subject field for individual report submissions SHOULD conform to the following ABNF:

   dmarc-subject = %x52.65.70.6f.72.74 1*FWS    ; "Report"
                   %x44.6f.6d.61.69.6e.3a 1*FWS ; "Domain:"
                   domain-name 1*FWS            ; from RFC6376
                   %x53.75.62.6d.69.74.74.65.72.3a ; "Submitter:"
                   1*FWS domain-name 1*FWS
                   %x52.65.70.6f.72.74.2d.49.44.3a ; "Report-ID:"
                   msg-id                       ; from RFC5322

The first domain-name indicates the DNS domain name about which the report was generated. The second domain-name indicates the DNS domain name representing the Mail Receiver generating the report. The purpose of the Report-ID: portion of the field is to enable the Domain Owner to identify and ignore duplicate reports that might be sent by a Mail Receiver.

12.2.1 Email

In the case of a "mailto" URI, the Mail Receiver SHOULD communicate reports using the method described in [STARTTLS].

The message generated by the Mail Receiver must be a [MIME] formatted [MAIL] message. The aggregate report itself MUST be included in one of the parts of the message. A human-readable portion MAY be included as a MIME part (such as a text/plain part).

The aggregate data MUST be an XML file subjected to GZIP compression. The aggregate data MUST be present using the media type "application/ gzip", and the filenames SHOULD be constructed using the following ABNF:

     filename = receiver "!" policy-domain "!" begin-timestamp "!"
                end-timestamp [ "!" unique-id ] "." extension
     unique-id = token
              ; "token" is imported from [MIME]
     receiver = domain
              ; imported from [MAIL]
     policy-domain = domain
     begin-timestamp = 1*DIGIT
                     ; seconds since 00:00:00 UTC January 1, 1970
                     ; indicating start of the time range contained
                     ; in the report
     end-timestamp = 1*DIGIT
                   ; seconds since 00:00:00 UTC January 1, 1970
                   ; indicating end of the time range contained
                   ; in the report
     extension = "xml" / "gzip"
   For the GZIP file itself, the extension MUST be "gz"; for the XML
   report, the extension MUST be "xml".
