    We are going to be migrating about customers from an old cpanel server to a new cpanel server.

    On the old server, the customers are using "" for their incoming/outgoing mail server name, because only the server's hostname has an SSL certificate that can be used for securely connecting to POP/IMAP/SMTP.

    If I understand correctly, the new AutoSSL feature included in cpanel means that the customer can get a free ssl cert for "" and use it to connect securely to POP/IMAP/SMTP. (Is that correct?)

    If this is correct... how can we make sure this certificate is created when their account is transferred, so the customer can start using "" as the incoming/outgoing mail server name and continue to connect securely?

    You can simply enable the AutoSSL feature and it will automatically attempt to issue a free cPanel-signed SSL certificate to the domain name (the process can take up to 48 hours). You can read more about AutoSSL and Domain TLS at:

    Manage AutoSSL - Documentation - cPanel Documentation
    What is Domain TLS - cPanel Knowledge Base - cPanel Documentation

    Thank you.
