If you have a large enough environment, you really ought to look into
Exchange server. You could get a hosted Exchange account from many
different providers....and this would be much better overall. POP3 is
really not suitable as a corporate mail protocol.


If the OP is not bothered about calendar and task sharing there are free
mail servers out there he could implement instead of Exchange.....
