Could it be that the DNS cache in the 510 is to dumb to understand
MX queries? Setup the router as the only nameserver in resolv.conf
and test with:
dig -t mx exim.org
This should return at least a section like this:

;; ANSWER SECTION:
exim.org. 301 IN MX 5 sesame.csx.cam.ac.uk.

If it doesn't, try again with your ISPs nameserver(s) in resolv.conf
