For anyone who's working on the list management BCP: I sign all my outgoing mail, and I have a feedback loop set up with Yahoo, which being very modern and advanced keys on signatures, not IP addresses. A few days ago I sent some messages to one of the Freebsd mailing lists. Today some Yahoo user who subscribes to that list hit the spam button. Freebsd's list software (Mailman, I think) doesn't sign, and doesn't strip any headers. So what happened? Yahoo saw my signature and sent the reports to me, which was of course useless since I don't run the list.
This is not a hypothetical problem--all of my recent Yahoo FBL reports have been for mail I sent to mailing lists elsewhere. The lists I do run sign their mail, and FBL reports for those lists are handled reasonably. My scripts do what they can with this stuff, but sending unsub commands to majord...@freebsd.org doesn't work.
