I run a *small* Mailman 2.x server on a VPS running CentOS 7, with Postfix. I have one E-Mail list with just under 500 members, about 60 of which have @yahoo.com addresses and another 15-20 with @aol.com addresses. For the past couple of weeks, Yahoo's servers have been "deferring" mail from my servers. It is not clear why. I have all of the DMARC, DKIM, and SPF stuff setup in Mailman (From: munging) and Postfix (DKIM signing, SPF records, etc.). I did some statistical analysis of Postfix's logs for just today. Sending mail to *every other* E-mail service is averaging a delay of under 3 seconds. Sending to Yahoo's servers is averaging a delay of just under 50000 seconds!
Is anyone else seeing this sort of problem? -- Robert Heller -- Cell: 413-658-7953 GV: 978-633-5364 Deepwoods Software -- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services hel...@deepsoft.com -- Webhosting Services ------------------------------------------------------ Mailman-Users mailing list -- mailman-users@python.org To unsubscribe send an email to mailman-users-le...@python.org https://mail.python.org/mailman3/lists/mailman-users.python.org/ Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: https://www.mail-archive.com/mailman-users@python.org/ https://mail.python.org/archives/list/mailman-users@python.org/
