Hello @roger-vikstrom ,

Thanks for reaching out.

Please kindly know, that the error message you shared (stream_socket_client(): Failed to enable crypto) is server-related. It indicates certificate verification failure on your server. Please, check this troubleshooting guide for more information.

When you get a chance, could you please contact your hosting support and ask them to look into the issue? You can provide them with the same SMTP error message you shared with us. They should be able to resolve the issue.

In case it helps to share, please note that the Other SMTP mailer does not use a dedicated API, which can lead to potential errors based on your website hosting settings. In cases where ongoing issues arise while using the Other SMTP mailer, we generally recommend switching to a transactional mailer option.

Transactional Mailers :
Transactional email service providers such as our #1 recommended mailer, SendLayer, are perfect for sending emails from your WordPress site. If it’s contact form notifications or e-commerce emails, they will deliver them quickly and reliably. Brevo (formerly Sendinblue), SMTP.com, SendGrid, and Mailgun are also transactional email service providers if you’d like to consider your options.

Transactional mailers also allow you to send emails with custom ‘From Email’ specific to your domain (examples: [email protected], [email protected]). If you’d like to check out more details on the mailers mentioned above or any others you may be interested in, you can see our complete guide here.

I hope that helps!
