First, why don't you send it imediatly, instead of doing that "loop
routing"?

You should not obfuscate, please.

If the refusal would be caused by "overloaded" Exim, there would be a
response like "4xx too many SMTP connections" or similar.
Are you sure, that an Exim instance is listening your local port 24
always? What does `exiwhat` tell you?
Does the Exim "server" process log something? The +pid log_selector may
help.
