Nop. The query works and returns the expected results when cut&pasted from
the logs (either exim or postgresql). I even sniffed the smtp dialogue and
tried to reproduce it, without any success (it just works if i'm trying it).

So this is either caused by a strange (but reproduceable) race-condition or
it somehow depends on the connecting ip address of the other side's server.
