You must configure the email application on the phone by adding your accounts to it. It will then connect to the email servers in its own right; it doesn't need any help or assistance from Thunderbird. The only adjustment I can think of that relates to Thunderbird is to see if the account uses (or can use) IMAP, because this is much better suited to working with email through several devices than the older POP. If Thunderbird connects to the server using POP, it may "eat" the messages before the phone gets to see them. And likewise if the phone uses POP (but it's unusual to use POP on a smartphone.) Both phone and Thunderbird should use IMAP to ensure greatest visibility of messages and consistency in what you see.
