Not all commands are included, unfortunately. Also, the list only shows commands that are available with doveadm as per configuration. Aki

Error: Filename keeps changing
by Ward Romp 24 May '16

24 May '16

Dear all, Two days ago, my ldap server (for authentication) crashed and I had to set up a new one. Everything works fine except the mailbox for one user (let's name him debugger). When I try to access his mail whatever way, dovecot complains about "Error: maildir_file_do(........): Filename keeps changing" For example, a command "doveadm copy -u debugger(a)boontje.net Archive mailbox Netspar" returns doveadm(debugger(a)boontje.net): Error: maildir_file_do(/var/mail/vmail/boontje.net/debugger/mail/Netspar/cur/14230…: Filename keeps changing doveadm(debugger(a)boontje.net): Error: Copying message UID 1 from 'Netspar' failed: Internal error occurred.

Growing number of dovecot processes
by John Oliver 24 May '16

24 May '16

OS is CentOS 6, dovecot-2.0.9-19 Just started using this server as a replacement for an old Debian server running an old dovecot. The number of dovecot processes just grows and grows until there are 100 concurrent login processes (we have maybe 40 or 50 users), and then nobody can log in any more. A reload resets, but the number of stuck processes climbs very quickly. We're authenticating against an OpenLDAP. Unfortunately, this system is not connected to the Internet so I cannot paste logs or output of commands. I've been Googling, but aren't hitting on the right phrase to describe this issue to uncover possible answers :-( If anyone can get me pointed in the right direction, I'd appreciate it. -- *********************************************************************** * John Oliver http://www.john-oliver.net/ * * * ***********************************************************************

No implicit INBOX with mailbox_list_index = yes?
by Karsten Heiken 23 May '16

23 May '16

Hello all, I am running a Dovecot Cluster (2.2.13 and 2.2.23 show the same behaviour) using dsync replication (as described here: http://wiki.dovecot.org/Replication) In addition to that I allow users to share mailboxes using IMAP ACLs. My problem is that I need to set "mail_shared_explicit_inbox = yes" if I want my users to see Inboxes of other users. If I leave mail_shared_explicit_inbox = no, then the user cannot see any Inboxes of other users: > * LIST (\Subscribed \UnMarked) "/" Sent > * LIST (\Subscribed \UnMarked) "/" Drafts > * LIST (\Subscribed) "/" INBOX When I set explicit_inbox = yes, then I can see the shared mailboxes: > * LIST (\Subscribed \UnMarked) "/" Sent > * LIST (\Subscribed \UnMarked) "/" Drafts > * LIST (\NonExistent) "/" shared > * LIST (\NonExistent) "/" shared/bob(a)luis.uni-hannover.de > * LIST (\Subscribed) "/" shared/bob(a)luis.uni-hannover.de/INBOX > * LIST (\Subscribed) "/" INBOX After some digging I found out that if I set mailbox_list_index = NO, then everything works even without explicit_inbox: > * LIST (\Subscribed) "/" Sent > * LIST (\Subscribed) "/" Drafts > * LIST (\NonExistent) "/" shared > * LIST (\Subscribed) "/" shared/bob(a)luis.uni-hannover.de > * LIST (\Subscribed) "/" INBOX Since we are migrating from Cyrus to Dovecot, our users are used to the behaviour of explicit_inbox = no, so I would like to keep it that way. I would simply leave mailbox_list_index disabled, but the comment states it is required for NOTIFY, which in turn is required by the rolling replication -- am I corrent? > # Mailbox list indexes can be used to optimize IMAP STATUS commands. They are > # also required for IMAP NOTIFY extension to be enabled. > # mailbox_list_index = yes What am I doing wrong or don't understand?

dovecot-sieve: require "mailbox" fails (Unbuntu 16.04)
by Karim 'Kasi Mir' Senoucci 20 May '16

20 May '16

Hello everyone, I'm moving some old procmail recipes to sieve, but having problems with it. The problem lies with the mailbox extension, which I'm trying to use as proposed in an example in the Dovecot wiki: > require ["variables","date","fileinto","mailbox"]; > > # Extract date info > if currentdate :matches "year" "*" { set "year" "${1}"; } > if currentdate :matches "month" "*" { set "month" "${1}"; } > > # Archive Dovecot mailing list items by year and month. > # Create folder when it does not exist. > if header :is "list-id" "dovecot.dovecot.org" { > fileinto :create "INBOX.Lists.${year}.${month}.dovecot"; > } I'm trying a similar rule (different condition, different mail folder), but cannot seen to get it to work. I always get the errors: > .DOVECOT: LINE 16: ERROR: UNEXPECTED '}' FOUND AT (THE PRESUMED) END OF FILE. > .DOVECOT: ERROR: PARSE FAILED. I'm using the standard dovecot packages from Ubuntu 16.04: > II DOVECOT-CORE 1:2.2.22-1UBUNTU2 AMD64 SECURE POP3/IMAP SERVER - CORE FILES > II DOVECOT-IMAPD 1:2.2.22-1UBUNTU2 AMD64 SECURE POP3/IMAP SERVER - IMAP DAEMON > II DOVECOT-MANAGESIEVED 1:2.2.22-1UBUNTU2 AMD64 SECURE POP3/IMAP SERVER - MANAGE SIEVE SERVER > II DOVECOT-SIEVE 1:2.2.22-1UBUNTU2 AMD64 SECURE POP3/IMAP SERVER - SIEVE FILTERS SUPPORT I was under the impression that these sieve extensions, including "mailbox", are builtin into dovecot/pigeonhole, or at least packaged into dovecot-sieve. Is that not the case? How can I get the example working under Ubuntu linux 16.04? Do I need to add or reconfigure something by hand? Thanks in advance for any help on the subject. Greetings Kasi Mir

I think this is intentional. The F(inish) tells the final response whether everything was OK or not, so all the work is done after that. The 'X' is described in code as: > > /* notify remote that we're closing. this is mainly to avoid > "read() failed: EOF" errors on failing dsyncs */ > o_stream_nsend_str(ibc->output, > t_strdup_printf("%c\n", items[ITEM_DONE].chr)); > > and on the receiving side: > > if (line[0] == items[ITEM_DONE].chr) { > /* remote cleanly closed the connection, possibly because of > some failure (which it should have logged). we don't want to > log any stream errors anyway after this. */ > dsync_ibc_stream_stop(ibc); > return DSYNC_IBC_RECV_RET_TRYAGAIN; > } > > So I think it only matters in error handling.

BUG?: Dsync over piped process (DSYNC_RUN_TYPE_CMD): EPIPE if X (done) is received in another write after F (finish)
by J. Nick Koston 20 May '16

20 May '16

Hi, It appears that dsync closes the file handle once it gets the F (finish) response even if it hasn’t received the X (done) response. If the X (done) response gets delivered in another write this will generate EPIPE in the connected process. This is much easier to replicate over SSL, however the trace is provided without SSL since its easier to see whats going on. Thanks J.

synchronous replication based on priority
by Sylvain Allemand 18 May '16

18 May '16

Hi, i see in this page (http://blog.dovecot.org/2012/02/dovecot-clustering-with-dsync-based.html) : "Optionally the replication plugin can also support synchronous replication of new mail deliveries. In this way it connects to replication-notify UNIX socket, tells it to replicate the user with sync (=highest) priority and waits until it is done or replication_sync_timeout occurs. The IMAP/LMTP client won't see an "OK" reply until the mail is replicated (or the replication has failed). The synchronous replication probably adds a noticeable delay, so it might not be acceptable for IMAP, but might be for LMTP." is this fonctionnality effective for LMTP ? If so, where is the config ? The wiki says that replication is asynchronous. Thanks for help, Best regards -- Sylvain Allemand <mailto:sylvain.allemand@math.u-bordeaux1.fr> Cellule Informatique Institut de Mathématiques de Bordeaux - UMR5251 05 40 00 68 86 www.math.u-bordeaux.fr/imb/cellule <http://www.math.u-bordeaux.fr/imb/cellule>

Reloading dovecot and postfix after updates
by ＠lbutlr 17 May '16

17 May '16

Recently someone used webmin to update dovecot, which went fine. However, after the update no one could login to the mail server because of the mismatch in the versions between what was installed and what postfix was expecting. Other that bapping the person on the head and saying “don’t do that” is there anyway to force a reload of postfix after dovecot reloads? Like adding a postfix reload to the dovecot rc.d script or someway of linking them so that if either version changes they both get reloaded? (I don’t even use webmin myself, so maybe it’s even possible through it?) I mean, it’s unlikely to happen again at this point, but still… -- "...and Digby considered how much he liked salt..."

Errors on Cross-Protocol Locking nbmand (ZFS Solaris)

I know this may not be a dovecot error, but any pointers why it is doing this so that I can report it to Oracle. I tried creating a small C program to mimic the same problem but no luck, since I know it would make it easier to get Oracle to fix it. # /usr/local/dovecot/sbin/dovecot --version 2.2.24 (a82c823) Thanks for now, Andrew -- Andrew Watkins * Birkbeck, University of London * Computer Science * * http://notallmicrosoft.blogspot.com * * UKOUG Systems SIG Chair * * UKOUG Tech committee * * tel: 020 7631 6720 *

Dovecot configuration: Home dir not found
by Divakar BM 17 May '16

17 May '16

Hi, I've my mail solution configured on Server-A with webmail, Dovecot and Postfix. I'm trying to deploy only Dovecot and postfix on Server-B to reduce IMAP/POP3/SMTP load on server-A. Please note server-B does not mailboxes. It should be mapped to mailboxes on server-A. While the LDAP query from Server-B to Server-A is going successfully, the imap service on Server-B is throwing the below error. imap(user(a)example.com): Debug: Home dir not found: /mail/vmail/**/ I guess imap is looking for *home dir* in server-B. How do I tel the imap that home dir is on server-A and not server-B. Please let me know if there exists a configuration parameter for the above.. Thanks Divakar

Sieve extension for testing for mailbox
by Jon Kristensen 16 May '16

16 May '16

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi! Which Pigeonhole Sieve extension should I use to process/test a message depending on whether the message is in a particular mailbox? (Is it the mboxmetadata extension by any chance? If so, I would appreciate if someone could tell me what the reason is for it not being enabled by default.) The reason I want to perform this test is that I have configured my MTA to deliver "outgoing" e-mails to my "Sent" IMAP folder, and these messages arrive unread. I would like to mark them as read using Sieve.

Hi, I've tried to upgrade to dovecot 2.2.24. It seems that lucene reindex issue should be fixed. But instead of this dovecot indexer-worker crashes very often for me. I'm attaching backtrace. Please let me know if you need backtrace from binary without optimizations. -- WBR, Dmitry

SSL on doveadm port
by Patrick Domack 15 May '16

15 May '16

I have been attempting to setup ssl on the doveadm port. So far this works fine, as long as the global certificate is used. I wanted to use a different certificate, one that machines the machine name, instead of the generic mail certificate, but I have not been able to figure out how to do this. Attempts to add the certificate in the services section with the ssl = yes option, cause syntax error, and dovecot doesn't start. Creating a protocol doveadm section with it, is ignored, and setting up a local section with it in it, is ignored also.

FTS and autoindex in a cluster?
by Peer Heinlein 15 May '16

15 May '16

In a dovecot replication cluster where both sides have fts_autoindex=yes we have a indexer-worker(user(a)example.com): Indexed 1 messages in INBOX on BOTH sides. a) Is that okay because the duplicated message will be skipped or doesn't harm? b) Or should "autoindex" only be activated on one side?

Dovecot 2.1.7 randomly lost emails
by Paolo Rinaldo 13 May '16

13 May '16

Hi Dovecot 2.1.7 Postfix 2.9.6 Maildir backend, emails filtered by a Postfix frontend (Sqlgrey, Amavis). Lmtp delivering emails using a simple sieve script. Ubuntu 12.04 VMware virtual server. When email are CCed to other recipients on the same domain (the same backend), sometimes they are lost. We hosts approx. 1500 mailboxes, the problem occurs one or two times a day. Recently I changed the frontend, the previous one was delivering one email for each recipient, we had a couple of error per year, we thought it was due to client-side error. The frequency increased with the new frontend, no more “splitting” messages for more than one recipient. The following sample is from a client using a POP3 connection, leaving emails on server. the Postfix mail.log May 11 01:26:55 lmail01 postfix/qmgr[7054]: 96E9CA6628: from=<sender(a)external.com>, size=11822371, nrcpt=2 (queue active) May 11 01:26:55 lmail01 postfix/lmtp[3106]: 96E9CA6628: to=<user-one(a)domain.com>, relay=mail4.robinson.it[private/dovecot-lmtp], delay=0.64, delays=0.45/0/0/0.19, dsn=2.0.0, status=sent (250 2.0.0 <user-one(a)domain.com> 0vNzHyptMlezHgAAk+lh+g Saved) May 11 01:26:55 lmail01 postfix/lmtp[3106]: 96E9CA6628: to=user-two(a)domain.com>, relay=mail4.robinson.it[private/dovecot-lmtp], delay=0.74, delays=0.45/0/0/0.29, dsn=2.0.0, status=sent (250 2.0.0 user-two(a)domain.com> 0vNzHyptMlezHgAAk+lh+g Saved) May 11 01:26:55 lmail01 postfix/qmgr[7054]: 96E9CA6628: removed the dovecot-info.log May 11 01:26:55 lmtp(7859, user-one(a)domain.com) Info: 0vNzHyptMlezHgAAk+lh+g: sieve: msgid=<003A2D931FFF0E48A2314A1ADC87E23E8E4BA1DE(a)t49-ms-exmb02.INTRANET.SAKSROOT.SAKSINC.com>: stored mail into mailbox 'INBOX' May 11 01:26:55 lmtp(7859, user-two(a)domain.com) Info: 0vNzHyptMlezHgAAk+lh+g: sieve: msgid=<003A2D931FFF0E48A2314A1ADC87E23E8E4BA1DE(a)t49-ms-exmb02.INTRANET.SAKSROOT.SAKSINC.com>: stored mail into mailbox 'INBOX' I cannot find the email 0vNzHyptMlezHgAAk+lh+g for user-two(a)domain.com<mailto:user-two@domain.com>, nor I cannot suppose problems on the client, nothing changed on the back-end.
