Help b1gMail 6.2

As I fill the fields

POP3-Host:
POP3-User:
POP3-Password:

So that the Pop3 functions correctly and and so that it serves for all the accounts? It would also like to know if it is necessary to create all manually the accounts for the Cpanel

Sorry, no support for warez copies of b1gMail.
Go and buy a license if you want b1gMail to work properly.
