Subject: Compiling with DomainKeys caused the test suite to show up some bugs:
X-Git-Tag: exim-4_52~34
X-Git-Url: https://git.exim.org/users/heiko/exim.git/commitdiff_plain/9a26b6b229299c6106f5ab917220f39277b21713?ds=inline

Compiling with DomainKeys caused the test suite to show up some bugs:
(1) The filter variables $n0-$n9 and $sn0-$sn9 were broken.
(2) The table of control names was missing some conditional names,
leading to the wrong name in some error messages.
