still you are not showing an example!
I have added a line exactly like yours to my test exim (4.30) and it
does *not* relay from arbitrary sources. Nico's suggestion to run
under the -bh flag is also good.

Because endpass usually expects something after it. I don't think
this has anything to do with this though.

I would then look at the changes introduced by version 4.31, as 4.30
does not show this behaviour.
