so, if you're using a wireless connection and lose packets, you may 
check the same POP mailbox again.  my observation is from personal 
experience.

now, the $1200 wireless i use at one of my client sites works all the time:

however, there are foot long Yagi antennae shooting cigar beams that 
prevent interference.  with only 3 users on the other end of the 11 Mbps 
link, their 10 user enterprise edition of QuickBooks Pro takes users on 
that side significantly longer to open the company's files.

wired ethernet does not experience the same problem at 100 Mbps.
