I set up most of them to forward into one centralized hub #email account. And created outgoing identities to spoof the various From headers.
In the last 5 years or so, anti-spam measures have made it increasingly shady to send from a server that doesn't host the MX records for the sending #domains (my 3 dozen emails use any of 5 different domains).
I don't know what past-Sherri was thinking but there's not much clarity on which address was used for what purpose.
I'm now in cleanup mode.
