Hi everyone, could someone help me to resolve this challenge. My exch server send to other domains but yahoo. The mails queue up on the server with error msg 421 4.4.2 Connection dropped due to socket error. I have tried out quite a number of measures but to know avail. The ISP told me there was no problem at their end. I have similar submissions in the forum but could still not resolve the challenge, but I have confidence that the forum could help me out based on what I have read sop far. MANY THANKS.
