>Note that historically, mailing list operators have been resistant to >the imposition of technical or operational changes. I think you're overstating things a little. I am very unsympathetic to changes that would require retraining all my users, e.g., putting the list address on the From: line. Technical changes that don't mess up the users are no more of an issue than any other software upgrade is to a small volunteer site. In particular, I've never seen anyone opposed to adding DKIM signatures to help recipient systems recognize the lists. R's, John
