The assistant will suggest using the name "mail.xxx.xxx" (but you can choose another), and it will also create an A record for that name. In this case, you should not create a CNAME record for it.

To create the above using the assistant, you'd override the suggested mail server names with "primary" and "pokie", then manually create the CNAME record for "mail" (if desired).

The point of the CNAME record named "mail" (above) is so that you can tell users to enter "mail.example.com" as their POP3/IMAP and SMTP servers. However, you should never use a CNAME alias in an MX record - doing so will cause some mail to bounce, and you may never find about it.
