Can you describe your system a bit more and what you are trying to do ?

It sounds like your Exim 4 server needs to supply some credentials in order
to relay through another server.

On my Debian system, this is:

/etc/exim4/passwd.client

The contents of this file take the form:

target.mail.server.example:login:password
