INBOX sharing does not work

Hello! INBOX sharing does not seem to work, although all other mailboxes work. User bar(a)example.de has shared a few mailboxes: # doveadm acl get -u bar(a)example.de INBOX ID Global Rights user=foo(a)example.de lookup read write-seen # doveadm acl get -u bar(a)example.de Sent ID Global Rights user=foo(a)example.de lookup read write-seen # doveadm acl get -u bar(a)example.de Drafts ID Global … [View More]Rights user=foo(a)example.de lookup read write-seen But user foo(a)example.de can't see the shared INBOX: # doveadm mailbox list -u foo(a)example.de Trash Sent Drafts Junk shared shared/bar(a)example.de shared/bar(a)example.de/Sent shared/bar(a)example.de/Drafts INBOX A review of the ACL does not explain the behaviour: # doveadm acl debug -u foo(a)example.de shared/bar(a)example.de/INBOX doveadm(foo(a)example.de): Info: Mailbox 'INBOX' is in namespace 'shared/bar(a)example.de/' doveadm(foo(a)example.de): Info: Mailbox path: /srv/mail-storage/mailhome/example.de/bar/Maildir doveadm(foo(a)example.de): Info: Per-user private flags in mailbox: \Seen doveadm(foo(a)example.de): Info: User foo(a)example.de has rights: lookup read write-seen doveadm(foo(a)example.de): Info: Mailbox found from dovecot-acl-list doveadm(foo(a)example.de): Info: User bar(a)example.de found from ACL shared dict doveadm(foo(a)example.de): Info: Mailbox shared/bar(a)example.de/INBOX is visible in LIST ---------- doveconf -n ---------- # 2.3.4.1 (f79e8e7e4): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.4 () # OS: Linux 4.19.0-10-amd64 x86_64 Debian 10.5 # Hostname: XXX.YYYY.de auth_master_user_separator = * auth_verbose = yes first_valid_gid = 401 first_valid_uid = 401 last_valid_gid = 401 last_valid_uid = 401 mail_gid = vmail mail_home = /srv/mail-storage/mailhome/%d/%n mail_location = maildir:~/Maildir mail_plugins = " acl listescape zlib" mail_uid = vmail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext namespace inbox { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = create special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox "Sent Messages" { auto = no special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = / type = private } namespace shared { list = children location = maildir:/srv/mail-storage/mailhome/%%d/%%n/Maildir:INDEXPVT=~/Maildir/shared/%%d/%%n prefix = shared/%%u/ separator = / subscriptions = yes type = shared } passdb { args = /etc/dovecot/master-users driver = passwd-file master = yes pass = yes } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile acl_shared_dict = file:/srv/mail-storage/mailhome/shared-mailboxes.db sieve = file:~/sieve;active=~/.dovecot.sieve zlib_save = gz zlib_save_level = 6 } protocols = " imap lmtp sieve" service auth { unix_listener auth-userdb { mode = 0777 } } ssl = required ssl_cert = </var/lib/dehydrated/certs/XXX.YYYY.de/fullchain.pem ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { driver = static } userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol lmtp { mail_plugins = " acl listescape zlib sieve" } protocol imap { mail_max_userip_connections = 20 mail_plugins = " acl listescape zlib imap_acl" } ------------------------------ I don't think it is relevant, but I don't want to forget to mention that /srv/mail-storage/ is an NFS share.

pop3_migration plugin

MDBOX DSYNC error: Broken physical size in mailbox
by paul-dovecotlist＠trainor.nz 17 Aug '20

Hi All, I currently have a small Dovecot server (Server A) and I've installed a second dovecot mailbox server (server B) and am trying to sync mailboxes from Server A to Server B. Both servers sit behind two dovecot directors on separate hosts and have identical config files (doveconf -n output below). Mailboxes on Server A are on an NFS mount. Server A has been working fine with no issues for a couple of years. I'm running this command on Server A: doveadm sync -u #user# tcp:#… [View More]newservername#:24245 Small mailboxes with few items are syncing OK.. but most mailboxes fail (sycn stops) with the following type of error: (Mailbox name, storage file, UID and sizes vary). dsync-local(#username#)<b2vTDKerOV/fAQAAZMK/0g>: Error: Mailbox INBOX: Cache /#usershomedirectory#/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index.cache: Deleting corrupted cache record uid=9: UID 9: Broken physical size in mailbox INBOX: read(/#usershomedirectory#/mdbox/storage/m.1) failed: Cached message size larger than expected (60616 > 8688, box=INBOX, UID=9) If I run it again, I'll get the same error, but with a new UID. If I do a local migration instead of server to server, I still get the errors. e.g. doveadm sync -u #user# maildir:~/Maildir-test/ I tried running a force resync (doveadm force-resync -u #user# -f "*) but it didn't help. There's no issues from an imap client accessing any emails. Using imapsync to sync affected mailboxes works fine for example. But... if I then run a dsync on Server B (doveadm sync -u #user# maildir:~/Maildir-test/) on an account that was successfully migrated with imapsync, I get the issue again. How worried should I be about these corrupted cache records, and any ideas how to resolve? Thanks in advance for your help!
