Would it be feasible to add an include or call facility into sieve? 
 That way a user could specify where the global rules should be run and 
put rules in front of them if they need any exceptions.  It would still 
require code in the users script, but most users will not change it 
anyway so a default script created for the user would be sufficient for 
most.  Unlike just setting the default script to be the global script, 
changes to the global script would not require updating all the users' 
scripts and trying to decide what to do if they have edited them.  It 
also gives users the option of selecting among multiple 
administrator-provided scripts.

This is probably a lot of work for at least the bytecode version -- the 
non-bytecode interpreter should be pretty easy to just include the 
contents of another file, and require handling might be tricky.

I haven't looked at the code, but it seems like it wouldn't be hard to 
have another directory under sieve for shared folders, such as 
sieve/shared/mailboxpath.  timsieved would need changes to allow them to 
be stored (by an administrator or perhaps by any user who has delete 
privileges on the folder), and it would complicate handling sieve 
scripts in home directories.
