Dovecot 2.2.14 and per user \Seen flags
by Thomas Robers 29 Oct '14

29 Oct '14

Hello, I have a Dovecot Installation Version 2.2.14 on CentOS 6.5 with shared folder. UserA shares his INBOX to user UserB. I activated "per user \Seen flags" with location = maildir:%%h/Maildir:INDEX=%h/shared/%%u:CONTROL=%h/shared/%%u:INDEXPVT=%h/shared I think the INDEXPVT setting activates this setting, right? I activated this setting when there were already several accounts in use. Before we used shared \Seen flags. But this setting doesn't work on my system. For example UserB marks several Messages as read in a shared INBOX from UserA and erverything seems alright but then suddenly all seen Messages are marked as unread again and I see the following error message in the log file: Oct 27 14:40:48 mail dovecot: imap(UserB(a)tutech.de): Error: /export/home/imap/UserB(a)tutech.de /shared/.INBOX/dovecot.index.pvt reset, view is now inconsistent Oct 27 14:40:48 mail dovecot: imap(UserB(a)tutech.de): Disconnected: BUG: Unknown internal error in=1020 out=2757 My Dovecot configuration is: root@mail:~# doveconf -n # 2.2.14: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-431.29.2.el6.x86_64 x86_64 CentOS release 6.5 (Final) ext4 auth_master_user_separator = * auth_mechanisms = plain login auth_verbose = yes disable_plaintext_auth = no mail_debug = yes mail_location = maildir:/export/home/imap/%Lu/Maildir mail_plugins = acl zlib 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 ihave duplicate mbox_write_locks = fcntl namespace { hidden = no ignore_on_failure = no inbox = no list = children location = maildir:%%h/Maildir:INDEX=%h/shared/%%u:CONTROL=%h/shared/%%u:INDEXPVT=%h/shared prefix = shared/%%u/ separator = / subscriptions = yes type = shared } namespace inbox { hidden = no inbox = yes list = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = INBOX/ separator = / type = private } passdb { args = /etc/dovecot/master-users driver = passwd-file master = yes } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile:/etc/dovecot/global-acls:cache_secs=300 acl_shared_dict = file:/export/home/shared-db/shared-mailboxes mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size zlib_save = gz zlib_save_level = 6 } protocols = imap pop3 lmtp sieve service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } unix_listener auth-userdb { group = vmail mode = 0660 user = vmail } } service imap-login { process_limit = 500 process_min_avail = 20 } service lmtp { inet_listener lmtp { address = 127.0.0.1 port = 24 } } ssl = required ssl_cert = </etc/pki/dovecot/certs/mail.tutech.de.crt_chain ssl_key = </etc/pki/dovecot/private/mail.tutech.de.key ssl_protocols = !SSLv3 !SSLv2 syslog_facility = local6 userdb { args = /etc/dovecot/dovecot-ldap-userdb.conf.ext driver = ldap } protocol lmtp { mail_plugins = acl zlib sieve } protocol imap { mail_plugins = acl zlib imap_zlib imap_acl } I don't know, is there something wrong with my configuration, am I missing sonething? Any hint would be helpful. Thank you Best regards Thomas

maildir++ quota support on dovecot
by Mirko ML 28 Oct '14

28 Oct '14

Some information about maildir++ that I have read: http://www.inter7.com/courierimap/README.maildirquota.html http://wiki2.dovecot.org/Quota/Maildir When I have to deliver a message with an MDA I can use dovecot-lda. If I have enabled "quota = maildir:User quota" I am pretty sure that in the mailbox on file system I find a file named "maildirsize" maildirsize on top contain something like this "xxxxxxxxxxS" that specifies the SIZE quota in bytes. LDA could delivery the message only when the SIZE written in mailbox is less than the SIZE defined by mail admin. "Each member of the list consists of an integer followed by a letter, specifying the nature of the quota. Currently defined quota types are 'S' - total size of all messages, and 'C' - the maximum count of messages in the maildir. For example, 10000000S,1000C specifies a quota of 10,000,000 bytes or 1,000 messages, whichever comes first." For this reason the value in bytes defined for the user must have S at the end. At the moment quota-maildir.c contains a control for S or C so I can find this in log: Quota rule: root=User quota mailbox=* bytes=20971520 messages=0 But quota-util.c do not contains a control for C and S, so probably the support of maildir++ format is not complete. Please let me know if I am wrong. -- Ciao Mirko

Namespaces (or another way) to put messages in a different drive
by Paulino Michelazzo 28 Oct '14

28 Oct '14

Hello people, I have a situation where I need to create a mailbox for clients where they put old messages (> 1year) but I would like to create this mailbox in a different disk. I have a server with the mailboxes and a storage mapped using NFS just to create those mailboxes for old messages. I was trying to namespaces but every time that I make the configurations, the authentication system stop and the clients can’t log in. I really don’t know if this is the best approach for my situation (mailbox with old emails in a storage) and, if namespaces can solve it. The infos that I have are: Dovecot version 2.1.7 mailboxes: Namespace configs: namespace { type = private separator = / prefix = #location defaults to mail_location. inbox = yes } namespace { type = private separator / prefix = storage/ location = /mnt/exibstor/%u inbox = no hidden = no list = yes } If someone knows how can I do that, I really appreciate it. Best regards, Paulino Michelazzo

Running 2.2.15 on FreeBSD 10.0. Forcing replication with: doveadm replicator replicate -f user(a)host.com on one user that I've seen some syslogs show up to see what's going on. Other users are fine. When I run the above command on the one user it produces a core dump. See below for syslog output and full backtrace: syslog output: Oct 26 22:44:09 d3cstorage dovecot: dsync-server(user(a)host.com): Panic: file dsync-mailbox-tree-fill.c: line 65 (dsync_mailbox_tree_get_selectable): assertion failed: (status_r->uidvalidity != 0) Oct 26 22:44:09 d3cstorage dovecot: dsync-server(user(a)host.com): Fatal: master: service(doveadm): child 67571 killed with signal 6 (core dumped) Oct 26 22:44:09 d3cstorage kernel: pid 67571 (doveadm-server), uid 127: exited on signal 6 (core dumped) bt full: #0 0x0000000040f73e1a in kill () from /lib/libc.so.7 #1 0x0000000040f72ac9 in abort () from /lib/libc.so.7 #2 0x0000000040bd6fa4 in default_fatal_handler () from /usr/local/lib/dovecot/libdovecot.so.0 #3 0x0000000040bd7ca1 in i_set_failure_internal () from /usr/local/lib/dovecot/libdovecot.so.0 #4 0x0000000040bd7249 in i_panic () from /usr/local/lib/dovecot/libdovecot.so.0 #5 0x0000000000428014 in dsync_mailbox_tree_fill () #6 0x000000000041e0e6 in dsync_brain_mailbox_trees_init () #7 0x000000000041bb27 in dsync_brain_run () #8 0x000000000041b41f in dsync_brain_master_init () #9 0x000000000042ac54 in dsync_ibc_init_stream () #10 0x0000000040be9443 in io_loop_call_io () from /usr/local/lib/dovecot/libdovecot.so.0 #11 0x0000000040beaafd in io_loop_handler_run_internal () from /usr/local/lib/dovecot/libdovecot.so.0 #12 0x0000000040be9688 in io_loop_run () from /usr/local/lib/dovecot/libdovecot.so.0 #13 0x000000000040ec49 in doveadm_dsync_main () #14 0x0000000000410fe9 in doveadm_mail_single_user () #15 0x000000000041a89c in client_connection_create () #16 0x0000000040be9443 in io_loop_call_io () from /usr/local/lib/dovecot/libdovecot.so.0 #17 0x0000000040beaafd in io_loop_handler_run_internal () from /usr/local/lib/dovecot/libdovecot.so.0 #18 0x0000000040be9688 in io_loop_run () from /usr/local/lib/dovecot/libdovecot.so.0 #19 0x0000000040b90a58 in master_service_run () from /usr/local/lib/dovecot/libdovecot.so.0 #20 0x000000000041ae15 in main () Config snippets: service doveadm { drop_priv_before_exec = yes inet_listener { port = 12345 } } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { group = mailsys mode = 0666 user = mailsys } unix_listener replicator { group = mailsys mode = 0666 user = mailsys } } Anything else I can provide?

dsync-server throwing Resource temporarily available

Running 2.2.15 on FreeBSD 10.0 with two back end storage boxes using TCP to sync. Seeing a couple of users that always seem to be throwing these kind of errors in the logs: dovecot: dsync-server(user(a)host.com): Error: write(/var/run/dovecot/replicator-doveadm) failed: Resource temporarily unavailable Just wondering what's the proper course of action to fix it? Thanks.
