This options allows you to set up your Server so that during each scheduled mail collection it will collect e-mail by POP3 from a private mailbox and deliver that e-mail directly to the user named as the recipient.
To configure this option you need to enter the login name in the mailbox
column, the associated password to access the mailbox and the server
on which the mailbox resides. Finally the user that the e-mail
should be delivered to is selected from a drop down list.
