As others have said, <> was invented for a reason. One of which is to
avoid loops. You ignore it at great peril. It won't just require another
sever with THIS patch running exim to cause a loop, but any other server
broken in a similar way.

People on this list have occassionally bemoaned the fact that with an
error report there was no real sender information provided somewhere.
But I think that that was a correct choice in the design of SMTP because
if the information were there, people would use it and loops would occur.

If you find that callbacks "need" this patch, then don't use callbacks.
