SMTP mail sending not working

Hi

One of the challenges I ran into moving to Digital Ocean is they don't provide a full Wordpress ready stack, most notably no SMTP mailer.

They said you just have to install Postmail yourself, which I tried to but failed with so much I gave up and asked if there was another option.

They suggested a Wordpress module, notably WP SMTP. I have installed this and configured it to use a third party SMTP sending service, and I got it to work for me fine.

However users have been saying they get no registrations email for CBPN.io, so it appears not all the time. So can I ask:

1) Could you try and see if you get emails
2) Help fix including suggesting any other possible scenarios for how to achieve the mail, I'm not wedded to WP SMTP

thanks!

Neil.
