Hi everybody,

I've been using pf on my home LAN for a while and now have an opportunity to use
 it at work.

Here's the problem: Company has several branches, connected over VPN and a centr
al Exchange server. Because of the slow connections to the internet and large nu
mber of branches/users email is increadibly slow especially during morning hours
.

I was wondering if somebody have any ideas how altq could be used allocate bandw
idth for email in this scenario. I can split the bandwidth for branches based on
 subnet addresses, but this will not separate exchange related trafic from, let'
s say http or file transfer.

Does anyone know which ports are used by Exchange or have any other ideas on thi
s.

Your help is greatly appreciated.
