Email DNS Settings

I have a URL that was successfully transferred to SquareSpace from Bluehost. The client wants to keep their email within Bluehost for now. 

Bluehost have provided me with the following DNS entry

Host: mail
Type: MX
Priority: 0
Data: mydomain.com

Do I need to keep any of the other DNS records?

autodiscover
@ MX
@ TXT
imap
smtp
webmail

or are they all handled by Bluehost?

Thanks.
