I think Sympa is just dandy, and am in the process of switching to it from mj2, but its DMARC hackery isn't much different from Mailman's. It does have remarkably good DKIM and S/MIME handling. I have a back end shim that rewrites mail addresses as required to avoid DMARC while remaining deliverable, e.g., if a message is from marissa@xxxxxxxxx, it rewrites it to marissa@xxxxxxxxxxxxxxxxxxxx and sets up a temporary local forward. It's grody but it works remarkably well. Anyone wants it, just ask. It's written in perl and the full forwarding groditude uses a litttle daemon (also written in perl) that will need some rewriting if your MTA isn't qmail. R's, John
