I don't DKIM-sign messages to the list (but I do normally DKIM-sign all my outbound mail) and there have been no problems so far. The correct way a mailing list should work is as follows: Suppose the envelope sender and header From: addresses are both "someone [ at ] example [ dot ] org" Then the addresses should be changed as follows: Envelope sender: <linux+bounces-whatever-someone=example [ dot ] org [ at ] linux-ottawa [ dot ] org> From: <linux [ at ] linux-ottawa [ dot ] org> Sender: <someone [ at ] example [ dot ] org> and then any existing DKIM-Signature header should be stripped and ideally a new one added that signes for linux-ottawa.org > You receive a sort of "DKIM signature invalid" error by the spam > filter, right? Yep. Adding the list footer alters the message body, which breaks the signature. Regards, Dianne.
