Based on current usage would instead plain rejecting e-mail with any HTML attachments be a viable way to move forward? > >I would offer help testing that this doesn't cause delivery issues, e.g. > >on some test email list, but it seems none of my domains is DMARC-infected > >:-/ > > Nevertheless, offers of help are appreciated (and rare). :-) I'm in a `p=none' domain at this e-mail address, so technically I would say it has been quite reasonably configured and therefore none of our people should have to choose between suffering from `From' munging or persuading the postmasters to change the configuration or switching to another MTA for mailing list submissions. Therefore I'd be happy to participate in testing a solution for disabling `From' munging for `p=none' domains. Maciej
