| SUBJECT | Subject: [Hangout - NYLXS] [Mailman-Users] Is it my server or Yahoo's
|
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
-at-yahoo.com addresses and another 15-20 with -at-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?
