I have some clients who cannot seem to email us and the reason I am told is 
that their
network utilises a bit in the IP header called "Explicit Congestion 
Notification" (ECN)
unfortunately this bit is rejected by some firewalls including our own 
GB1000 (3.2).
Has anyone else had this issue, and how is it generally overcome..? What 
are the
dangers etc etc etc....

Thanks in advance for your help.

Frank
