Certificate warning in your email program

Are you getting a warning about the security certificate in your email program or on your phone? This means the server name you entered doesn't match the server's certificate.

What the warning looks like

• The target principal name is incorrect (Outlook)
• Cannot Verify Server Identity (iPhone and iPad)
• The certificate belongs to a different site or Confirm Security Exception

The causes with us

• You use mail.yourdomain.com, imap.yourdomain.com or smtp.yourdomain.com as the server, and that name doesn't point to your package or isn't included in the certificate.
• You use your domain name as the server, but your website is hosted elsewhere, or your domain doesn't point to us (yet), for example during a migration.
• Your antivirus software replaces the certificate. You can tell because Issued by shows the name of your antivirus software, such as Norton, Avast, AVG or ESET.

How to fix it

1. Look up your package's server name in My WebOké under My Products, in the Server column.

   

2. Enter that server name, such as linux2023.webawere.nl, as both the incoming and the outgoing server. That way you'll never get a certificate warning.
3. Prefer to use your own domain name? Then make sure your domain points to your package and has a valid certificate (see Requesting a free Let's Encrypt certificate).
4. Is your antivirus software listed under Issued by? Turn off scanning of encrypted email in your antivirus software, or update it.

Please note: Don't just dismiss a warning like this by choosing "continue anyway". If you do, you won't notice when something really is wrong.
