# Mail Headers

 * After testing the free version I now installed the paid enterprise version
 * A remark on the header
 * `List-Subscribe: <mailto:admin@example.com?subject=subscribe>`
    `List-Unsubscribe:
   <mailto:admin@anpa.onl?subject=unsubscribe>`
 * would be more useful as
 * `List-Subscribe: <mailto:admin@example.com?subject=subscribe LIST NAME>`List-`
   Unsubscribe: <mailto:admin@anpa.onl?subject=unsubscribe LIST NAME>`
 * because now we know which list the recipient wants to unsubscribe from.
 * My email client, if it finds the unsubscribe header, inserts a unsubscribe message
   as the first line and if clicked and confirmed sends an empty email to [admin@example.com](https://wordpress.org/support/topic/mail-headers/admin@example.com?output_format=md)
   with the subject line as defined above.
 * Are these List-headers really necessary? They seem to be a legacy of Mailman.
   
   Who looks at the mail headers for List-Post and List-Help?

 * Hi [@antonv](https://wordpress.org/support/users/antonv/),
 * thanks for the improvement suggestion.
    We will add the list name in the subscribe/
   unsubscribe subjects in the next release.
 * The headers are defined in [IETF RFC 2369](https://www.ietf.org/rfc/rfc2369.txt),
   i.e. they are an internet standard, not something Mailman-specific.
