Slow Response in Outlook Express(Pop3)

While the network run 2 or 3 days, incoming and outgoing
mail will slow down. I need to restart the broadband
modem and broadband router to make it normal.
7 computers connect in the switch and share the broadband
network. I have brought a new router, switch and check
the computers are Virus Free but the problem still going
on.


Pls help me!!
