Working with a (dot)co email address?

    Will this plugin work with a .co (dot)co email address. I have configured the plugin in exactly the same way I have done so on many other websites with the same hosting company but normally with .com emails.

    On the hosting with a .co address I get continual error messages. Forms do get sent and are received but go to Junk instead of the inbox and test emails sent from the plugin do not arrive although emails sent to the mailbox do arrive and mail can be sent from the account and received by the recipient.

    The error log shows:
    For Forms:

    Mailer: Other SMTP
    SMTP Error: Could not authenticate.

    Source

    Formidable Forms

    Suggestions to overcome this welcome

    Hi @adrian33000,

    Thanks for reaching out! The WP Mail SMTP plugin acts as a bridge between your website and your preferred email provider or transactional mailers like SendLayer or Brevo. This setup allows your website to send emails using an authenticated email account or domain.

    There are no restrictions based on your domain extension (e.g., .com, .co). You should be able to configure the WP Mail SMTP plugin successfully regardless of the TLD.

    Based on the issue you’ve described, it seems there may be an email deliverability issue with your new domain. When you have a moment, please send a test email from your WordPress site (via WP Mail SMTP -> Tools) to the email address displayed in this tool and check your email deliverability report.

    You can then share this report with your email provider. They should be able to make necessary adjustments, such as updating SPF and DKIM records for your domain. If your email sending domain or IP is blacklisted, they should be able to assign a new IP for you.

    In the meantime, you can try configuring an alternative mailer on your site.

    I hope this helps! Thanks!

    I cannot understand the inability to authenticate. The email address is the site admin address and I have double checked the password by using it to log into the web mail account. Something seems very odd as I have also confirmed the DKIM and other email settings which are all showing as correct

    I have deleted and reinstalled the plugin and it now works ok so I think there was an original install problem.
