Hello All, I've recently had some troubles with email going to Yahoo/AOL/Verizon.
We've been getting these. see https://help.yahoo.com/kb/postmaster/SLN3434.html <ter...@aol.com>... Deferred: 421 4.7.0 [TSS04] Messages from 64.246.100.9 temporarily deferred due to user complaints - 4.16.55.1; see https://help.yahoo.com/kb/postmaster/SLN3434.html Warning: message still undelivered after 4 hours I've tried to work with Yahoo Postmaster Support but keep getting the same form email seemingly no matter what I do. Does anyone have any recommendations for what might be the best course of action? We tightened up our SPF records, but don't have DKIM enabled at the moment. Thanks much, Ken Amplex Internet
