Adding an IP to the "domain" table doesn't cause a loop. Not at all.
But of course, if you use the "domain" module function wrongly then
there could occur a loop, or any unexpected error.

In my previous mails I've tryed to explain that you are performing
authorization based on the From domain, which is highly vulnerable (so
you are using "domain" module for a wrong purpose). It seems that
removing the IP from the "domain" table fixes your problem and you
don't care this security hole. So I will paste again my previous
question and invite you to think again about it ;)

- Do you need authorization based on source IP or based on From domain?
  (note: Anyone in the world can spoof a request with *any* domain/IP)
