Global default admin-enforced sieve script?

[mailing list subscriber]

Do devs accept we admins need this, and if yes when can we expect it

 This has been previously precisely described back in 2007:

 Also in 2004, with reference to 2001:

 So ten years after the first occurence of this feature request, do I

 and move to something else, or is there any hope for $subject
 *REALLY*SOON*?

 Many thanks.
