I set up a new inbound mail gateway. It forwards mail to multiple domains inside our WAN. The change-over is working perfect for all domains, but one. The log files show "Deferred: Connection reset by domain name". When I attempt to telnet to it via port 25 I get Connected to domain name (x.x.x.x). Escape character is '^]'. Connection closed by foreign host. I have success sending mail and telneting from the original relay mail server (on the same subnet) To this same server. The tech on the other end has checked his settings and feels he has made the necessary allowances. Could it be the way my new server is talking on port 25? Raymond
