Hi,
I have a fairly new WP/WooCommerce store and I have WP Mail SMTP installed.
I seem to be getting a ‘Mail delivery failed’ message back to my inbox every time it attempts to send a mail to a customer with a Yahoo/AOL account… It’s happened with two customers now. Gmail, Hotmail etc. seems to be fine.
Error message below:
host mta6.am0.yahoodns.net [98.136.96.91]
SMTP error from remote mail server after pipelined MAIL FROM:<info@sevenmushrooms.co.uk> SIZE=4469:
553 5.7.2 [TSS09] All messages from 185.56.84.3 will be permanently deferred; Retrying will NOT succeed. See https://postmaster.yahooinc.com/error-codes
Reporting-MTA: dns; se15.mailspamprotection.com
Is there anything I can do about this? Thanks very much.
