See http://peach.ease.lsoft.com/scripts/wa-peach.exe?A2=lstown-l;8e660448.1404 A more interesting question might be, will other large email providers (e.g. Microsoft, Comcast, Gmail, etc.) decide to also jump on the DMARC bandwagon. Again, personally, I think there may be good chance this could happen. As to your technical questions, the DMARC project has a draft of suggestions of how MLMs (Mail List Managers like LISTSERV) should alter their behavior to comply with DMARC. http://www.dmarc.org/supplemental/mailman-project-mlm-dmarc-reqs.html Basically they propose a re-write of the From: address to something that won't fail the DMARC lookup. That may affect how recipients of list mail can easily (or not) reply to the sender (original From:). It may also affect how list mail sorts into reading folders in recipients email client programs. There may also be increased risks of mail loops. As to what that means for LISTSERV specifically I can't say, but it is hard to imagine this could be implemented without some code changes so very likely there will be an update or interim release of some kind. As to your wakeup call, I know than many sites have not implemented list-level changelogs which are crucial in logging the massive numbers of auto-deletions and producing lists of addresses to be re-added to lists. Site admins will be scrambling to accomplish this if they haven't implemented changelogs. ############################ To unsubscribe from the LSTSRV-L list: write to: mailto:[log in to unmask] or click the following link: http://peach.ease.lsoft.com/scripts/wa-PEACH.exe?SUBED1=LSTSRV-L&A=1
