Just wondering if anyone can shed some light to this mystery of mine. My exchange 2K server seems to be running fine but one of our vendor can not get through. Everytime they send an email to us, they get "Recipient's server exceeded time for connection". It seems to be blocking their domain name but I can't find the block anywhere in my system including firewall. Any idea?
