We’re having troubles with sending e-mail on behalf of a domain, from a wordpress application, while using Cloudflare.
WordPress is hosted on server A with it’s own IP-adress
Domain is hosted on server B with it’s own smtp settings, but rerouted by Cloudflare
Wordpress (with Easy smtp WP plugin) is trying to send e-mails (i.e when signing up), but we can’t manage to get the application sending the mails.
The domainregistrar is saying we need to whitelist the wordpress hosting domain on Cloudlfare to send the mails on behalf of the domain.
I’ve tried to set up a Firewall rule to allow the hosting IP - but this did not help.
Can anyone help me out?
