Add X-PopBeforeSMTP header for mail sent via POP-before-SMTP

Add X-PopBeforeSMTP header for mail sent via POP-before-SMTP it is bit confusing me

Add X-PopBeforeSMTP header for mail sent via POP-before-SMTP [?]
Include a list of POP-before-SMTP senders in the X-PopBeforeSMTP header when relaying mail. (exim 4.34-30+ required) (NOTE: To disable POP-before-SMTP, turn off antirelayd in Service Manager.)

POP before SMTP is an email protocol that allows users to check email from different IPs without having to log in repeatedly.
Enabling this setting requires the mail server to append a list of email addresses a user checks using POP before SMTP to the X-PopBeforeSMTP headers of all that user's outgoing messages.
As this measure may compromise the privacy of your users, enabling it is not recommended unless absolutely necessary.
To make your selection, click the button corresponding to the option you wish to use. The default value for this item is Off.

if i set this value off should i Antirelayd check box ticked or un-ticked ?

does that email user requires authentication before pop ?

Unticked, if you wish to disable POP-before-SMTP.

I really want to know what is the difference between X-PopBeforeSMTP and Antirelayd un-checked ?.

The former is I believe for adding a header denoting when pop before smtp has been used to message headers, the latter is disabling pop before SMTP itself.
