Hello release team, after some investigation, I believe I have the issues in sa-exim under control. The broken spool files were due to a memory corruption that could easily be worked around. The issue with CHUNKING was mainly that SpamAssassin uses CRLF to terminate header lines when the input message uses CRLF line endings, and the CR needs to be stripped. With this taken care of, I don't think SA-Exim is so buggy that it needs be removed from Debian. It does have a couple of advantages over the built-in spam ACL conditions, as outlined in README.Debian.
