I had my server configured to support ARC for a while, but eventually gave up after the implementation annoyed me. My reason for believing this and subsequently giving up on ARC is that I've yet to find a way to get recipients to trust my server's ARC seal. After some investigation and discussion, I got the impression that having recipients trust your ARC seal was effectively a good old boys club. I fully acknowledge that was not the intention. But the lack of good distribution system and the need for the recipient to trust my ARC seal even after validation was ... intractable. I would LOVE to learn that I am wrong and that things are better than my current working understanding. So, please, by all means, correct me if I'm wrong. > Nope. There is ARC code in Mailman 3, but we are still using Mailman > 2. I hear there is a migration plan, eventually. I feel like Mailman 2 to Mailman 3 is about like upgrading from Windows 95 to Windows NT or 32-bit Windows to 64-bit Windows. Similar in function, similar in appearance, and similar behavior, but completely different and not completely compatible under the hood. > In the meantime we're using a local hack I invented and Henrik > implemented that rewrites From: addresses in a way that makes it > obvious who they are, e.g. > > bob@bigcorp.com > > turns into > > bob=40bigcorp.com@dmarc.ietf.org It's not Sender Rewriting Scheme in form, but it sure seems like SRS in spirit. > We set up temporary forwards so direct replies work.

It also embodies ideas that I've had for a while. To whit, the mailing list is it's own proper first rate terminal entity that people communicate with as the destination or source, not merely an expansion system. -- Grant. . . . unix || die
