Your question is not clear, what is the situation exactly?

1. Your client sofware can't send mails through your server? or

2. Your server can't deliver mails to another server? or

3. Your server can't relay mails through another server (smart relay)?

Since you send this to the exim list I assume you have a server
running exim, if that server is refusing relaying mail to your clients
(point 1), you probably did not configure relay_from_hosts, something
like:

hostlist relay_from_hosts = 127.0.0.1:192.168.10.0/24

But the problem could be something else, you have to check your
configuration (it is very well documented on the comments that
surround the options); look mostly at the top of the file.

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
