Responding to list

[nilshellerhoff]

When responding to a mail sent by mailiszt, the response should be sent to mailiszt first and then be distributed to the intended recipients from there.

Example:

• A, B, C are members of list L [email protected]
• E is not a member
• list L is configured to allow externals to adress the list
• when E sends a mail to the list, A, B and C will receive it
• if now A responds, the response should be sent to [email protected]. Mailiszt should then be able to recognize that this is a response to a mail sent by mailiszt.
• now mailiszt forwards the response from A to the members of the list B,C and E
• if now E again answers, the entire list is going to get the answer (not possible if setting the list in CC without setting reply-to header manually)

How to implement?

• using in-response to header fields etc. to identify the message which was responded to. Are these fields standardized? How do different email clients handle this?
• use plus addressing in the reply-to field [email protected]. Not supported by every provider/mail server software
• some header field which is guaranteed to be retained in an answer mail?
• Including an ID in the body or subject of the email (should always work)
