No. You will be OK if you deliver non-yahoo email to yahoo (assuming that yahoo accepts email from you). You *may* get into long term trouble (blacklisting) *IF* you deliver yahoo email to any other company/person that checks yahoo's DMARC record. Yahoo's recent change (DMARC p=reject) stipulates for everyone else to outright reject yahoo email from anyone other than yahoo. This has the potential for others to report your mailinglist as doing something malicious. -Jim P. ------------------------------------------------------ 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
