How do I white-label hostnames?

By default, your own brand domain is used as your mail & FTP hostnames. As a 20i Reseller, you can white-label hostnames to match your branding. This means instead of the following hostnames being displayed to your StackCP users:

• ftp.stackcp.com
• imap.stackmail.com
• smtp.stackmail.com

These hostnames are displayed instead:

• ftp.yourdomain.com
• imap.yourdomain.com
• smtp.yourdomain.com

You can enable or disable this from the Reseller Preferences >> StackCP Settings, under the Branding heading.

Securing your brand domain with an SSL certificate

It's important to note that an SSL certificate is advised for your brand domain name when using white-labelling. Without an active SSL certificate on the domain that is used for the hostname, connectivity issues may arise. As a result, an error may occur when setting up a mailbox via a mail client. This is an example of the error that you may encounter without an active SSL certificate:

Can't safely connect to server. (Certificate hostname not usable for server: imap.yourdomain.com) 

• If you are using 20i's nameservers, you can use our Free Wildcard SSL. Read more about applying the free SSL 
• Alternatively, you can purchase an SSL from 20i, but it should be a Rapid SSL Wildcard certificate to ensure all sub-domains are covered.

Note: If you delete the hosting package that the SSL certificate is installed on, the SSL certificate won't cover the domain, or any of the sub-domains. This means all hostnames won't be covered by the SSL certificate and may cause connectivity issues.
