Customs email headers and/or subjects tags

코드 어디에도 %{optional_tags} 같은 값이 email custom headers 사이트 설정에 추가된 헤더에 치환되는 부분이 보이지 않습니다. 제가 발견한 것은 커스텀 헤더 값을 설정하는 데 사용되는 이 메서드입니다:

github.com/discourse/discourse

lib/email/sender.rb

main


      
              return
            end
            true
          end
          
          #
          # Two behaviors in the mail gem collide:
          #
          #  1. Attachments are added as extra parts at the top level,
          #  2. When there are both text and html parts, the content type is set
          #     to 'multipart/alternative'.
          #
          # Since attachments aren't alternative renderings, for emails that contain
          # attachments and both html and text parts, some coercing is necessary.
          #
          # When there are alternative rendering and attachments, this method causes
          # the top level to be 'multipart/mixed' and puts the html and text parts
          # into a nested 'multipart/alternative' part.
          #
          # Due to mail gem magic, @message.text_part and @message.html_part still
          # refer to the same objects.

이 메서드는 다음 위치에서 호출됩니다:

github.com/discourse/discourse

lib/email/sender.rb

main


      
              @message.header[key] = our_value
            end
          
            value = header_value(key)
          
            # Remove Auto-Submitted header for group private message emails, it does
            # not make sense there and may hurt deliverability.
            #
            # From https://www.iana.org/assignments/auto-submitted-keywords/auto-submitted-keywords.xhtml:
            #
            # > Indicates that a message was generated by an automatic process, and is not a direct response to another message.
            @message.header[key] = nil if key.downcase == "auto-submitted" && smtp_group_id
          
            # Replace reply_key in custom headers or remove
            if value&.include?("%{reply_key}")
              # Delete old header first or else the same header will be added twice
              @message.header[key] = nil
              @message.header[key] = value.gsub!("%{reply_key}", reply_key) if reply_key.present?
            end
          end

설정값이 의도된 대로 어떻게 사용되며, 커스텀 헤더에 어떤 값이 치환될 수 있는지 Discourse 팀에서 좀 더 자세한 정보를 얻어보겠습니다.
