Thanks to Timo's advise (much appreciated!), I shifted the mail root to /mail
dir. Now I have a simplest config where the bug triggers flawlessly. Feel free
to test on a clean Debian machine; it’s a 100% reproducible.
1. Setting up the environment:
groupadd -g 500 vmail && useradd -M -u 500 -g vmail -s /bin/false vmail &&
mkdir -p /mail && chown vmail:vmail /mail
2. Copy-paste dovecot.conf from the bottom of this mail & start dovecot.
3. Save eml to INBOX of user1 with CLI.
doveadm save -u user1 -m INBOX /tmp/1.eml
4. Both works: saving with APPEND too.
curl -u "user1:hello" -k imap://localhost:143/INBOX --upload-file /tmp/1.eml
5. Share rights with user2.
doveadm acl add -u user1 INBOX user=user2 lookup read write write-seen
write-deleted insert post expunge create delete admin
6. Try SEARCH ALL & SORT from owner. It works pretty well.
curl -u "user1:hello" -k imap://localhost:143/INBOX -X "UID SEARCH ALL"
SEARCH 1 2
curl -u "user1:hello" -k imap://localhost:143/INBOX -X "UID SORT (REVERSE
ARRIVAL) US-ASCII NOT DELETED"
SORT 2 1
7. Try same thing over imapc from user2 (over shared namespace).
curl -u "user2:hello" -k imap://localhost:143/shared/user1/INBOX -X "UID SEARCH
ALL"
SEARCH 1 2
curl -u "user2:hello" -k imap://localhost:143/shared/user1/INBOX -X "UID SORT
(REVERSE ARRIVAL) US-ASCII NOT DELETED"
SORT
SORT does not return any UIDs, but SEARCH does. Do you see that? Can You help
with this, please?
