Exim received this line. It is not valid. When using LOGIN
authentication, the client is supposed to send just "AUTH LOGIN", but
yours has send additional data. Exim is interpreting the additional data
as the first data field - i.e. the user name. (The data sent decodes as
"ipc" incidentally.)

Exim sends a prompt, asking for the password.

There's something missing here. There should be an incoming line before
that outgoing SMTP line. Has the debug output got mangled somehow?

Exim's now expecting a command, not more authentication data, so it
says:
> SMTP>> 500 Unrecognized command
Now it receives a blank line, again not expected:

The client now starts sending the message:

All goes well until Exim asks the client to send the message.

The connection got dropped. There is little more that one can deduce
from this, I'm afraid.

Hmm. Why is is sending that 421 twice? Were there two connections?
Sorry I can't be more helpful here.
