Agree, but it does not :-)

At least with version 3.0.8 :

localhost> info user/ren at devenv.blue
{user/ren at devenv.blue}:
private:
  check: NIL
  checkperiod: NIL
  comment: NIL
  sort: NIL
  specialuse: NIL
  thread: NIL
  expire: NIL

  sieve: NIL
  squat: NIL
shared:
  check: NIL
  checkperiod: NIL
  comment: NIL
  sort: NIL
  specialuse: NIL
  thread: NIL
  annotsize: 0
  duplicatedeliver: false
  expire: NIL
  lastpop: NIL
  lastupdate:  4-Nov-2019 15:32:13 +0000
  news2mail: NIL
  partition: bm-master__devenv_blue
  pop3newuidl: true
  pop3showafter: NIL
  sharedseen: false
  sieve: NIL
  size: 32310
  squat: NIL
  synccrcs: 2599665889 0
  uniqueid: ee8ede37-153a-4650-bf94-3da7d4f52043

* OK rename user/ren/Trash at devenv.blue user/rename/Trash at devenv.blue
. OK Completed

But if I use the version without an explicit partition, the new mailbox ends up in :

> info user/rename at devenv.blue
{user/rename at devenv.blue}:
private:
  check: NIL
  checkperiod: NIL
  comment: NIL
  sort: NIL
  specialuse: NIL
  thread: NIL
  expire: NIL
  news2mail: NIL
  sieve: NIL
  squat: NIL
shared:
  check: NIL
  checkperiod: NIL
  comment: NIL
  sort: NIL
  specialuse: NIL
  thread: NIL
  annotsize: 0
  duplicatedeliver: false
  expire: NIL
  lastpop: NIL
  lastupdate:  4-Nov-2019 16:43:36 +0000
  news2mail: NIL
  partition: default
  pop3newuidl: true
  pop3showafter: NIL
  sharedseen: false
  sieve: NIL
  size: 32310
  squat: NIL
  synccrcs: 2599665889 0
  uniqueid: ee8ede37-153a-4650-bf94-3da7d4f52043


which forces me issue a second command in my imap session :

. RENAME user/rename at devenv.blue user/rename at devenv.blue bm-master__devenv_blue
* OK rename user/rename at devenv.blue user/rename at devenv.blue
* OK rename user/rename/Drafts at devenv.blue user/rename/Drafts at devenv.blue
* OK rename user/rename/Junk at devenv.blue user/rename/Junk at devenv.blue
* OK rename user/rename/Outbox at devenv.blue user/rename/Outbox at devenv.blue
* OK rename user/rename/Sent at devenv.blue user/rename/Sent at devenv.blue
* OK rename user/rename/Trash at devenv.blue user/rename/Trash at devenv.blue
. OK Completed


Which moves the mailbox to the partition where I want it (its original one).


The problem with the non-atomic rename is that our replication target receives data belonging to the default partition, which is not desired or expected.
