Messages don't show up. My list splits into multiple archives.
Many lists send either a confirmation request or acknowledgement here .
Take care of any confirmations that the list requires. The Mail Archive automatically detects when it receives mail from a new list. Thus, you are encouraged, although certainly not required, to send a test message to the newly archived list. If you are adding several lists to the archive, send a separate and distinct test message to each one. During normal operation, email is archived shortly after it is received.
