Hello, @ArchieTheFirst

What I could suggest here is using an SMTP plugin for your WordPress site.

That way you will be able to specify an SMTP server with authentication which your emails would be going through. You could for example use SendGrid’s SMTP service. This would drastically increase the delivery rate of your emails as well compared to using plain PHP mail.

I’ve been using this plugin for a while now and it works very well: Easy WP SMTP.

Hope that this helps! Regards, Alex


I just did a quick test and it works for me. Maybe you need to check if there’s any firewall on your network level. Or check /var/log/mail.log for any error.
