Repair your MTA installation

Still not fixed? Copy the whole message, not only the code, and check your log in the Fix tool. It is read on your own computer.
About this code
MTA's own client shows a CC code when something fails before or during a connection: the address, the nickname, a module it could not load, or the connection itself. MTA's own documentation gives CC42 as Command-line mod failure.
