The Exiscan ACL patch for exim 4.30 is now at
http://duncanthrax.net/exiscan-acl/
This is only a version bump release, there are no functional changes.
I do have a work-in-progress version, however it is not finished. It
will contain some major improvements, but it won't be ready until
January due to my current major workload :)
Note to PH: there is a "leftover" file from patching sieve.c in the 4.30
source tarball: src/sieve.c.orig
