For Exim we need code changes to get it working in the best possible manner.  
Upstream is interested in accepting patches.

Exim periodically re-exec's itself for different tasks.  What we want is for 
it to execute exim-FOO instead where FOO is the task in question.  On a 
non-SE system exim-FOO could be a sym-link to exim, on a SE system it would 
be a wrapper program that executes the main exim program in a different

Does localStrict.te really provide a benefit?

Yes, there is still work to be done there.

Yes, it does more things and requires more access.

Now further changes:
It's probably best to permit getattr access when read access is permitted, I 
omitted this in the fs_allow_tmpfs_file_read patch I sent you.

I'll send other patches soon.
