Either the problem is that you're sending broken domain names, e.g.
<TEST_DOMAIN>.com ("<" for example isn't a valid character in domain names),
or you're obfuscating, in which case please don't: see
http://wiki.exim.org/DontObfuscate for why not.

Either you're using a waaaay old version of Exim, or you're looking at the
wrong documentation. Please check your exim version (exim -bV) then find
documentation more appropriate to your version, e.g. perhaps
http://www.exim.org/exim-html-4.69/doc/html/spec_html/index.html if you're on
4.69.

Without knowing the domain name in question (see above), impossible to say.

Let's have some more solid information then we'll see if we can help more.

Cheers!
