Some users have problems receiving large emails.=20 A qpopper is running for that user, their outlook express is open, I can = ping their machine, but no mail is flowing. I've also seen the same thing happening when they are sending. Just to understand the principle: TCP/IP is supposed to be reliable, = right? If something happens, TCP/IP is supposed to do retransmits. If TCP/IP looses a package anyway, will the programs "on top" = (application layer?) just wait, or will they too start retransmitting? It seems like if the traffic has stopped, no amount of waiting will = cause traffic to start again. This happens on both analog PM2 and ISDN PM3.=20 The route to the portmasters goes via a cisco doing ospf. The mailserver is (sorry) still li*ux, but this has happened also when I = moved some customers to try using a Fbsd stable box. I wouldn't mind a solution, but I'm mostly asking this to enhance my = knowledge of tcp/ip...
