So I tried that. Unfortunately, it seems that some part of Exim eats
the backslashes before they are seen by the ACL. I don't know if this
happens only in -bh mode or if it would happen with a running daemon
too. I'm not trying the latter ATM.
For instance, if I say this in the -bh dialog:
RCPT TO:<it\z@???>
the local part being tested, according to the >>> output, is just "itz",
which of course ends up being accepted.
I think this is a bug, do you agree?
