So my server says they block php mailer and unauthenticated SMTP emails.
Fine. I installed WP Mail SMTP, filled in the settings, and now the contact form has an error message.
I did the test email through WP Mail SMTP, and it gives an error. It doesn't seem to authenticate...?
Here is the full error, with my actual emails, domain name and passwords changed for my privacy:
The result was:
bool(false)
