What it means
A CD code appears when a connection to a server fails, is refused, or ends. Most of them carry a second line with the server's own reason. MTA's own documentation gives this code as Local connection failure.
How to fix it
Work down the list and stop when it is solved.
Copy the whole message first
Write down every line MTA shows, not only the code. The rest of the message often names the file, the server or the reason, and that is what tells you which step below applies.
Try the connection again
Close MTA, open it again and connect once more. A single failed attempt can come from a restart on the server or a short break in your own connection.
Still stuck? The Fix tool reads MTA's own log on your computer and points at the matching steps. Nothing is uploaded.
