This is clear, and useful information. fmp.com publishes a proper SPF record, and with regard to the mail server DMARC mitigation program I wrote for Courier, the envelope sender is "al...@fmp.com", which can possibly be adjusted, but which matches "postmas...@fmp.com" which I'm using for the body From header on munged emails, and on top of this FMP publishes "a mx ptr ip4:198.58.125.221 mx:linode.fmp.com -all" for SPF, which grabs just about everything and should be OK. -- Lindsay Haisley | "The first casualty when FMP Computer Services | war comes is truth." 512-259-1190 | http://www.fmp.com | -- Hiram W Johnson ------------------------------------------------------ Mailman-Users mailing list Mailman-Users@python.org https://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: https://mail.python.org/mailman/options/mailman-users/archive%40jab.org
