[Dovecot] 2.0.3 Bug - hanging issue
by Alan Brown 25 Oct '10

25 Oct '10

We had this this morning: Oct 25 12:36:34 msslat dovecot: imap(keh2): Error: user keh2: Initialization failed: Namespace '#mbox/': mkdir(/stage/mail/imap1/keh2/mail) failed: Permission denied (euid=2291(keh2) egid=101(luci) missing +w perm: /stage/mail/imap1, euid is not dir owner) Oct 25 12:36:34 msslat dovecot: imap(keh2): Error: Invalid user settings. Refer to server log for more information. Oct 25 12:36:35 msslat dovecot: imap-login: Login: user=<keh2>, method=PLAIN, rip=128.40.73.160, lip=128.40.73.13, mpid=26736 Oct 25 12:36:35 msslat dovecot: imap(keh2): Error: user keh2: Initialization failed: Namespace '#mbox/': mkdir(/stage/mail/imap1/keh2/mail) failed: Permission denied (euid=2291(keh2) egid=101(luci) missing +w perm: /stage/mail/imap1, euid is not dir owner) Oct 25 12:36:35 msslat dovecot: imap(keh2): Error: Invalid user settings. Refer to server log for more information. Because the parent directory was rwxr-xr-x root.root The problem is that for some reason dovecot then wedged and a lot of other stuff piled up behind it, causing people to complain their mail wasn't coming through. Load average climbed to over 100. Creating the user directories freed things up...

I have been, but I've seen no similar reports and it may still be in 2.0.6. I will update to that version during a planned maintenance window tomorrow.

[Dovecot] virtual plugin broken ? dovecot 2.0.6
by Robert Schetterer 25 Oct '10

25 Oct '10

Hi Timo, looks like virtual plugin is broken now with my setup dovecot 2.0.6 cant say to which version it stopped working ( didnt tested it trough all ) but has worked i see nothing special in log why it stopped working it should show unseen mail i.e in folder Junk too with pop3 clients, but only shows new inbox mails after all i am confused what using better pop3_uidl_format = %08Xu%08Xv ( most compatible ) or pop3_uidl_format = %g ( better with virtual ) pop3_reuse_xuidl = ? what ist the most compatible/konservative setting with maildir on a cluster filesystem pop3_save_uidl = ? what ist

[Dovecot] Auto delete older messages in SPAM folder
by Thiago Henrique 25 Oct '10

25 Oct '10

Hello, I use Cyrus in my mailservers and I intend to migrate it to Dovecot. Cyrus has a setting that purge the emails from a mailbox under a pre-defined criteria. For example: EVENTS { ... # At 12:01 delete messages older than 60 days in SPAM folder deletespam cmd="ipurge -d 60 -f user/*/SPAM" at=1201 } Is there in Dovecot any setting like this ? Thank you. -- []'s Thiago Henrique Network Administration Digirati Networks K8 Networks

[Dovecot] Problems converting to maildir with dsync in 2.0.6
by Nicholas Riley 25 Oct '10

25 Oct '10

I'm trying to convert from an old Dovecot (1.0.15) and mbox to a new Dovecot and maildir. I'm running into several problems with dsync which are causing my mboxes not to convert. If I use LAYOUT=fs (as I'd prefer) I get an error because I have a mailbox called "subscriptions", and none of my messages convert. Is there a way to get dovecot to put its own metadata in dotfiles instead? (I guess I can rename my mailbox too :-) % dsync mirror mbox:~/Mail dsync(nriley): Error: read() failed with subscription file /home/nriley/Maildir/subscriptions: Is a directory dsync(nriley): Error: Can't update subscription +/INBOX: Internal error occurred. Refer to server log for more information. [2010-10-21 20:17:55] [...] Also, what "server log" is it referring to above? So I tried without LAYOUT=fs, and dsync successfully converts some mailboxes, then crashes: % dsync mirror mbox:~/Mail dsync(nriley): Error: Maildir: 6ef533cd4cdb1fd454b0226bfc851bb3:2, changed UID 1846529 -> 1846531 dsync(nriley): Panic: file maildir-save.c: line 892 (maildir_save_sync_uidlist): assertion failed: (ret > 0) dsync(nriley): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0 [0xb7ea21f1] -> /usr/lib/dovecot/libdovecot.so.0(default_fatal_handler+0x47) [0xb7ea2317] -> /usr/lib/dovecot/libdovecot.so.0(i_error+0) [0xb7ea2544] -> /usr/lib/dovecot/libdovecot-storage.so.0(maildir_transaction_save_commit_ pre+0x858) [0xb7f2ab58] -> /usr/lib/dovecot/libdovecot-storage.so.0 [0xb7f2501f] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_transaction_commit_fu ll+0x85) [0xb7f67eb5] -> /usr/lib/dovecot/libdovecot-storage.so.0(index_transaction_commit+0x94) [0xb7f24c14] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_transaction_commit_get_c hanges+0x42) [0xb7efeaa2] -> /usr/bin/dsync [0x8056ed2] -> /usr/bin/dsync [0x80570f0] -> /usr/bin/dsync(dsync_worker_select_mailbox+0x2e) [0x8055b2e] -> /usr/bin/dsync [0x80507e6] -> /usr/bin/dsync [0x8050a3b] -> /usr/bin/dsync(dsync_brain_msg_sync_new_msgs+0x12) [0x8050c12] -> /usr/bin/dsync(dsync_brain_msg_sync_more+0x2e1) [0x8050261] -> /usr/bin/dsync(dsync_brain_sync+0x309) [0x804e949] -> /usr/bin/dsync [0x804f953] -> /usr/bin/dsync(dsync_brain_sync+0x72e) [0x804ed6e] -> /usr/bin/dsync [0x804f7d0] -> /usr/bin/dsync(dsync_brain_sync+0x55d) [0x804eb9d] -> /usr/bin/dsync(dsync_brain_sync_all+0x18) [0x804f668] -> /usr/bin/dsync(main+0x5a1) [0x804da51] -> /lib/libc.so.6(__libc_start_main+0xe5) [0xb7d29455] -> /usr/bin/dsync [0x804d2e1] [1] 30528 abort dsync mirror mbox:~/Mail I tried running it in GDB but that crashed GDB, so hopefully the above info is OK... % gdb --args dsync mirror mbox:~/Mail (gdb) run Starting program: /usr/bin/dsync mirror mbox:\~/Mail [Thread debugging using libthread_db enabled] [New process 30652] Executing new program: /usr/bin/doveconf warning: Cannot initialize thread debugging library: generic error warning: Cannot initialize thread debugging library: generic error warning: Cannot initialize thread debugging library: generic error warning: Cannot initialize thread debugging library: generic error [New process 30652] [Thread debugging using libthread_db enabled] [1] 30651 segmentation fault gdb -q --args dsync mirror mbox:~/Mail I'm using the Debian packages from rename-it.nl.

[Dovecot] Recommendation for OCFS2 filesystem type
by Andre Nathan 25 Oct '10

25 Oct '10

Hello When creating an OCFS2 filesystem, one can specify a "filesystem type" option: -T filesystem-type Specify how the filesystem is going to be used, so that mkfs.ocfs2 can chose optimal filesystem parameters for that use. The supported filesystem types are: mail Appropriate for file systems which will have many meta data updates. Creates a larger journal. datafiles Appropriate for file systems which will host a rela‐ tively small number of very large files. A small journal is selected. Cluster size will be at least 128K. Considering I'm using a separate partition for the dovecot indices, and that I'm using mdbox, would it be more appropriate to use 'datafiles' for the mail location partition and 'mail' just for the indices? Or would 'mail' be appropriate for both even with the larger files created by mdbox? Thanks, Andre

[Dovecot] Shared folders, please help.!

Hello all, First of all sorry for this, it has been discussed many times, but i can not make it work. I tried for a long time now. I do something wrong, but i do not know what. First of all, i have virtual users, with virtual domains. Mail is stored in /usr/local/virtual/domain name/user So if my domain is domain.com and my e-mail address is johan(a)domain.com the directory is /usr/local/virtual/domain.com/johan i followed the wiki, and my configuration looks like the following. beasty dovecot # dovecot -n # 2.0.5: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.1-STABLE amd64 ufs auth_debug = yes auth_debug_passwords = yes auth_mechanisms = plain login auth_verbose = yes dict { acl = mysql:/usr/local/etc/dovecot/dovecot-dict-acl-sql.conf quotadict = mysql:/usr/local/etc/dovecot/dovecot-dict-quota.conf } disable_plaintext_auth = no first_valid_gid = 1004 first_valid_uid = 1004 last_valid_gid = 1004 last_valid_uid = 1004 log_timestamp = .%Y-%m-%d %H:%M:%S . mail_access_groups = vmail mail_debug = yes mail_gid = 1004 mail_location = maildir:/usr/local/virtual/%d/%n mail_uid = 1004 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 mbox_write_locks = fcntl namespace { hidden = no inbox = yes list = yes location = prefix = separator = / subscriptions = yes type = private } namespace { inbox = no list = children location = maildir:/usr/local/virtual/%%d/%%n/shared/:INDEX=/shared/%%n prefix = shared/%%d/%%u/ separator = / subscriptions = no type = shared } passdb { args = /usr/local/etc/dovecot/dovecot-mysql.conf driver = sql } plugin { acl = vfile acl_anyone = allow acl_shared_dict = proxy::acl autocreate = Trash autocreate2 = Junk autocreate3 = Sent autocreate4 = Drafts autocreate5 = Templates autosubscribe = Trash autosubscribe2 = Junk autosubscribe3 = Sent autosubscribe4 = Drafts autosubscribe5 = Templates quota = dict:::proxy::quotadict quota_warning = storage=95%% /usr/local/bin/quota-warning.sh 95 quota_warning2 = storage=80%% /usr/local/bin/quota-warning.sh 80 } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { group = vmail mode = 0660 user = vmail } } service dict { unix_listener dict { mode = 0600 user = vmail } } service imap-login { inet_listener imap { address = 192.168.50.200 port = 143 } } service pop3-login { inet_listener pop3 { address = 192.168.50.200 port = 110 } } ssl = no userdb { args = /usr/local/etc/dovecot/dovecot-mysql.conf driver = sql } protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep imap_idle_notify_interval = 2 mins imap_logout_format = bytes=%i/%o imap_max_line_length = 64 k mail_plugins = quota imap_quota autocreate acl imap_acl mail_log notify } protocol pop3 { mail_plugins = quota trash pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } protocol lda { auth_socket_path = /var/run/dovecot/auth-master mail_plugins = quota acl mail_log notify postmaster_address = postmaster(a)test.com sendmail_path = /usr/local/sbin/sendmail } That is my config file.

[Dovecot] problem with subscriptions=no and changed separator ?
by Lutz Preßler 25 Oct '10

25 Oct '10

Hello, Dovecot 2.0.5+ (Debian "automatic package" 2.0.5-0~auto+5). If I use the following namespace definitions namespace personal { inbox = yes location = maildir:~/Maildir separator = ^ prefix = type = private } namespace others { type = shared separator = ^ prefix = shared^%%u^ location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = children } namespace virtual { location = virtual:~/Maildir/virtual:LAYOUT=maildir++ separator = ^ prefix = virtual^ type = private } (virtual should not matter, but I have not tested without.) I have problems with subscriptions for the shared mailboxes: SUBSCRIBE ^shared^user^box leads to entry shared^user^box in ~/Maildir/subscriptions file. All subscriptions for folders in personal namespace use the "layout" separator (".") thought. LSUB "" "*" does not show the just subscribed folder, but it does after I manually change the entry to read shared.user.box Bug?

[Dovecot] shared folders general question
by Johan Hendriks 25 Oct '10

25 Oct '10

Hello all. Thanks to the patience off Timo i finally got my shared folders working. I have one more question. Is it possible if you share the inbox, that all subfolders will be visable to. I can not see the subfolders of the shared inbox. This is not very useful if the user which shares his inbox, has sieve rules active that stores e-mail directly into subfolders. Thanks regards, Johan
