A little addition that also helps a bit: move the content of the From: header to the Reply-To: header and replace From: with the local account that is forwarding the message. All mail then originates from your domain and a reply to a forwarded message will go to the original sender.
This is what many mailing lists (including this one) do nowadays, but unfortunately it has a downside, it will almost certainly break the DKIM signature, meaning that if you do this you will probably need to also remove the original DKIM signature then re-sign the message yourself. At the point you are legitimately telling other server that the message does indeed originate from you and it makes the consequences of forwarding SPAM even worse than they already were.
For general forwarding of mail I really wouldn't recommend this approach. Peter _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
