+1. There's an RFC under development that goes into some detail on this topic, but the long and short of it is that a multi-From message is invalid by the specs and really ought to be rejected by the submission agents as well as receiving MTAs. RFC6376 said this too. -MSK _______________________________________________ dmarc-discuss mailing list [email protected] http://www.dmarc.org/mailman/listinfo/dmarc-discuss NOTE: Participating in this list means you agree to the DMARC Note Well terms (http://www.dmarc.org/note_well.html)
