Mine may not be the best solution
but I present it anyway
Make a different directory for each - "Board" and "Mailing_List"
The first filter sends every mail for [TheList] to "Mailing_List"
The second filter sends mails from A to "Board"
The third filter sends mails from B to "Board"
The fourth filter sends mails from C to "Board"

Personal mails from A B and C you will need to send to some other place
again.
