Relaying to "johnny@??? through my system appears
to work when I try "exim -d -bh 159.90.10.114". However
when I try it for real from a remote site, my system 
bounces the attempted relay with:
    unknown local-part "johnny@???" in domain "dpmms.cam.ac.uk"
So, as Peter says, the spam wont actually get though.


Worth noting that exim -bh doesn't report the failure though.
