Question
What license do I need for a Mail, DNS, or Database node?
Answer
You may use any tier of cPanel license[1] for any type of cPanel node however, the account limitations of that license tier will still apply. For example, if you were to use the Solo tier on a mail node, you would only be able to distribute 1 account to that mail node.
cPanel Partners[2] may have pre-release access to node specific licenses which will be viewable in Manage2 as they become available. If partners have questions about what node specific licenses are available and what the cost would be, they may reach out to their Account Manager or review Manage2.
