Hey @kenneth1976
Please kindly note that the error message is returned by your SMTP provider. It usually means an issue with your SMTP credentials or some error during the authentication process.
It is critical to make sure you have the right credentials. When you get a chance, please double-check the password you’re using with the SMTP connection to be sure it’s correct.
In case it helps, please check out our step-by-step guide on setting this up here.
The SMTP host provider will be able to provide the following details that you can then use when connecting the mailer’s SMTP server.
- SMTP Host: The outgoing server listed in your email provider’s SMTP settings.
- Encryption: The type of encryption used for the SMTP connection (TLS, SSL, or none).
- SMTP Port: The port your provider uses for SMTP connections.
- Authentication: Turns authentication on or off. Most providers require it to be on.
- SMTP Username: Your email address.
- SMTP Password: You may need to generate an app password for your account depending on the host.
You can then test your server credentials in an isolated environment to discard/confirm any issues local to your site. A tool like this https://smtpserver.com/smtptest would do the job.
Please keep me posted on how it went.
hi and thanks for the reply.
I have testet the smtp with success. So it is not not the credidentials that is causing thoe error.
Hey @kenneth1976
Thanks for the update,
In this case, there is a chance plugin conflict could be the cause. This means another plugin could interfering with the connection process.
Please make sure you don’t have other SMTP plugins active.
Also sometimes forms plugins or themes for example, can have their own SMTP settings.
I would recommend to performa full plugin conflicts check, here is how.
Let me know how it went, and if you found a culprit.
Thanks.
