Just in the last couple of weeks, one of our vendor suddenly is having problem sending email to me. They can receive our emails without any problem. When they send us email however, we never get it any they get " Recipient's server exceeded time for connection". They are able to do a nslookup to our exchange server, and they are also able to ping us. So far, this is the only domain that I know of that is having problem sending to us. Anyone got any idea as to what I should be looking for?
Thanks
