Check the retry times (see the exinext utility). Maybe that's the clue
that you need. If there are 2 MX records, for hosts A and B, but host A
failed recently, Exim will not try it again until its retry time comes -
even for a new message.
Try a delivery with retry time override: put a message on the queue
using -odq and then force a delivery using -M (check these options out
in the manual).
