Hi again.
I've somewhat cleaned the stuff up (at the usual location
http://lxnt.info/stuff/exim*).
The define is now named SUPPORT_CYRUS_PWCHECK, as was intended from the beginning, and location
of pwcheck daemon socket is configurable in Local/Makefile. Also debug (D_auth) messages
became more sane, and passwords were thrown out of them.
By the way, is there some way to issue the
454 Temporary authentication failure
instead of regular 535 reply? I'd like to do this in case pwcheck.c can't connect to the socket,
to facilitate debugging of lameusers.
./lxnt
