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. -- greg -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
