But you missed option #1:

1. Operate strictly as a "forwarder," where the RFC5321.RcptTo field
is changed to send the message to list members, but the RFC5322
message headers and body are not altered.
Pros: Receiving systems can validate the DKIM signature of the message
author, if one was present.
Cons: Senders that depend solely on SPF for authentication will still
fail. Precludes many customary features of mailing lists, such as
"Subject:" tags, list footers/disclaimers, etc.
