Hardlink+Sieve has never worked. The fix is a bit complicated. Here's my
TODO entry about it:

 - remove mail_deliver_session after all, do all the stuff transparently
   by hooking into mailbox_copy().
     - use this hook also to do the mail deduplication: 1) sort all destination
       users, 2) create mail_user only once for each user, 3) remember in
       src_mail the previously copied mail, 4) use that for mailbox_copy()ing
       to following recipients
     - make sure this removes duplicate dbox mails when sieve saves mail to
       multiple mailboxes

Hi Timo,
glad to know it is in your TODO list ;)

Any rough ETA on that?
Thanks.

It's been for many years.

Right now it doesn't seem likely to be developed anytime soon.

Hi list,
any news regarding hardlinks + sieve/pigeonhole setup?

Hardlinking seems a very important feature to me, and I would really 
like to get it working.

Thanks.

It's a rather difficult change and also pretty low priority right now.
I'd be happy to explain the details to whoever wants to develop this, but I
wouldn't be surprised if it was still unimplemented a few years from now.
