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.
A quick search revealed these two MSKB articles:

Summary:
POP3 and IMAP4 clients are easy, static ports; Outlook clients are a
problem, due to dynamic ports. Exchange can be set to use a specific
range of ports, and you can have pf/altq use those.
Is there any reason you can't just use the Exchange server's IP address?
It would be simpler (and more accurate) than chasing dynamic ports.
