How big are the emails? If people send really big attachments as a
matter of course, the emails can clog the line easily. It is not
unusual to see a few pages of Word inflate to a few MB (hereafter
b is bit, B is byte). Let's do the math, assuming you really get 
128Kb/s, and 1B=8b:

1 MB / 128Kb/s = 62.5 s = 1 minute + change.

If you send something like that, it does not surprise me that it
takes a low priority ICMP packet a couple of seconds to get through
this traffic jam twice.

Am I being stupid? Again?
