the reason is simple

something like "T1" here costs far too much to dedicate it just for mails.

for the same price i can get four "4Mbit/s" ADSL's (which i have now), 
that actually gives 4Mbit/s download speed, but only 512kbps upload.
if you substract ACK's needed for 4Mbit/s download, little is left.
my ipfw rules manages all this so web browsing works fine, but mail output 
is a problem now.
