In order to be able to send the header at all, you must be able to pass the 3 way handshake for TCP which sends packets in both directions. What you may be seeing is a problem involving packet size, either the sending host is outputting a packet too big for its local net, the local gateway is not fragmenting properly, or the destination host is not reassembling properly. Mike Brescia PS: can you list some hosts, both BBN and non-BBN, to which you cannot send mail?
