Attempting to set up Easy WP SMTP to send newsletters from my site, but I get variations of "connection failed(111)" errors on any combination of outgoing SMTP servers and authentication options, except one. My only successful set up is;
SMTP Host; relay-hosting.secureserver.net
Type of Encryption; None
SMTP Port; 25
SMTP Authentication; No
The MAJOR problem is that these settings are failing the automated spam filters for my clients, as the address appears to be "spoofed" to spam filters. NOT a good look for a business.
I need a solution within WordPress that authenticates the outgoing message with my Office365 credentials, so that my customers feel completely safe getting emails from my business.
