Thanks! I can give it a shot, but there's no ETA, since I have no clue how to use exim. I just looked at the source, and it appears to use setuid (as opposed to setresuid) to drop privileges, and it will dlopen user-requested libraries. I think that the other issues in the original post may be CVE-worthy despite their low impact -- they can, at best, cause sandbox protection to be less effective than intended. --Andy
