Hi there @glostservice1,
The error you’re seeing indicates that the connection can’t be made because the server you’re trying to reach can’t authenticate the connection. One reason this can happen is if the credentials you’re using are incorrect. Double-check with your SMTP provider to make sure you’re using the correct credentials.
Additionally, you may also want to check with your host to make sure they allow SMTP connections to be made with PHP. In some cases, the host will block PHP from being able to make SMTP connections. In those cases, you would need to use a mailer to connect to a service such as SendLayer, Brevo, etc.
Check out this guide in our documentation. It walks through each mailer we support and includes the benefits of each: https://wpmailsmtp.com/docs/a-complete-guide-to-wp-mail-smtp-mailers/
I hope that helps! Have a great day!
Thank you for the asnwer.
Te problem is that when I activate your plugin, the emails are not sent at all from the contact forms on my site. When I deactivate your plugin, the emails are sent out but they end up in the junk folders when they’re recevied.
Hi there @glostservice1,
The reason for that would be the error. When that error comes up, it’s essentially saying that WP Mail SMTP can’t connect to your mailer service (the SMTP server you’re trying to reach).
If the SMTP credentials are correct, check with your host to make sure they are not blocking SMTP connections. Often that’s the case, and they don’t usually tell people when they implement such a block.
Otherwise, you may want to use one of the other mailers. If you’re looking for a free solutions, Brevo offers a free tier. You just have to sign up on their site and follow the setup guide on our site. It’s a pretty easy process and can get you up and running soon.
I hope that helps! Have a great day!
Thank you for your reply. I’ve contacted my host and they say “SMTP port is opened in our server.”
Any idea why I’m still getting this problem?
Many Thanks,
Fabio.
