Not with great precision. The simple version is don't add to the body and don't change the subject line or the signature is guaranteed to break. I haven't done any testing to see what works. The DKIM standard answer is resign the message with the list domain's signature. Personally, I think that problems like this will be solved through integration of SPF and DKIM and some TBD domain reputation system. Scott K P.S. I'm assuming you meant this to go to the list. Apologies in advance if I guessed wrong. -- ubuntu-server mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam
