Dovecot can't read mail, creates duplicate directories
by John Oliver 11 Sep '14

11 Sep '14

CentOS 6.5, dovecot 2.0.9-7 I used http://www.linuxmail.info/postfix-dovecot-ldap-centos-5/ to configure LDAP authentication for postfix and dovecot. I can log in to dovecot via IMAP, but it cannot read messages. It does wind up creating alternate directories though: [joliver@localhost ~]$ sudo ls -l /var/vmail/ total 8 drwx------. 3 vmail vmail 4096 Sep 10 15:00 testuser1 drwx------. 3 vmail vmail 4096 Sep 10 14:59 testUser1 [joliver@localhost ~]$ sudo ls -l /var/vmail/testuser1/ total 4 drwx------. 3 vmail vmail 4096 Sep 10 15:00 mail [joliver@localhost ~]$ sudo ls -l /var/vmail/testuser1/mail/ total 0 [joliver@localhost ~]$ sudo ls -l /var/vmail/testUser1/ total 4 drwx------. 5 vmail vmail 4096 Sep 10 14:59 Maildir [joliver@localhost ~]$ sudo ls -l /var/vmail/testUser1/Maildir/ total 12 drwx------. 2 vmail vmail 4096 Sep 10 14:59 cur drwx------. 2 vmail vmail 4096 Sep 10 15:01 new drwx------. 2 vmail vmail 4096 Sep 10 15:01 tmp [joliver@localhost ~]$ sudo ls -l /var/vmail/testUser1/Maildir/new/ total 8 -rw-------. 1 vmail vmail 444 Sep 10 15:25 1410387938.Vfd02I1e89M2893.localhost.localdomain -rw-------. 1 vmail vmail 453 Sep 10 15:26 1410387970.Vfd02I1e8cM685475.localhost.localdomain [joliver@localhost ~]$ telnet localhost 143 Trying ::1...

Just a wild-ass guess, but shouldn't "master_user=%u" be something like "master_user=muser" where "muser" is the master user as defined in your master password file?

outlook 2013
by Bob Miller 10 Sep '14

10 Sep '14

I am trying really hard to wrap my head around why people insist on using this program... Where I have outlook 2013 users, I have had nothing but problems getting their mail to work with imap. my solution has been to set them up with pop, which works just like it always has. Or move them to a different program. recently, I have a customer who requires multiple machines, all using outlook 2013, to access the same email address, so pretty much have to use imap. if I set up just one of the machines with imap, it works more less as expected, with hiccups such as mail taking an hour or two or more to show up. But shortly after I connect a 2nd machine to the same account, one or both machines start to go wonky. Symptoms include deleted items returning, read messages becoming unread again, and duplicates being constantly created and deleted. The last I can confirm by watching in webmail and refreshing the inbox every few seconds; as mail shows up and deletes in outlook, so it does in webmail too. On my test machine connected to the same server, I have evolution, outlook and thunderbird all connecting to one account with no problems. Well, outlook hiccups, but it's not unusable. And I have other users on the system that share email accounts across a variety of other clients and platforms, including older versions of outlook. I have tried checking message rules, there are none; removing all folder subscriptions; running scanpst, which finds errors even before the account finishes syncing and ever time I run it after that; I have looked for viruses/malware; I have confirmed there is no forwarding or some trickery happening on the server; chkdsk and similar hardware checks all come up clean, the computers are only a couple of months old; I have got certs set up with SANs and the CA installed such that outlook does not error on the certificate; and I have tried just about every combination of settings that seem relevant. The one thing that does seem to work, at least for a few minutes or an hour or two, is deleting and recreating the accounts on one of the computers. But the problem inevitably returns in short order. Surely people have outlook 2013 connecting via imap to dovecot without problems; is there some special trick that google is hiding from me? -- Computerisms Bob Miller 867-334-7117 / 867-633-3760 http://computerisms.ca

Dovecot replication
by Hoggins! 10 Sep '14

10 Sep '14

Hello list, I'm trying to achieve very simple replication, but I'm not sure if I'm starting the good way. I have two Dovecot servers that use the same GlusterFS storage. Of course, the indexes get corrupted eventually, even if I apply an "NFS-like" configuration. So I'd like to synchronize my two servers with each other. I'm trying to follow this page : http://wiki2.dovecot.org/Replication, but I have to admit that it's not really self-explanatory. I got several errors, so I decided to start fresh, and that is why I'm not giving you any configuration, but I prefer asking if I have the prerequisites. The page states that my userdb should have "user listing", and that you can check it by issuing `doveadm user '*'`. But I don't know what it's supposed to produce, apart from my userlist (my userdb is the system passwd file). As my servers are located on the same private LAN, I decided I would not go with the SSH replication solution, but with the simple mutual TCP connection... Maybe this is a wrong start. Any help will be appreciated. Thanks in advance !

Hi. I'm using exim that delivers email over LMTP to dovecot 2.2.13. I noticed that dovecot LMTP service is sometimes (reare but repeats) mixing users. Example below. There is one mail (msgid=<1ACE53B70631CA45B62348E4EE8757493731A59E@KRMXA41>) that is going to be delivered to multiple local recipients.

Replication problem
by Ve (HOME) 10 Sep '14

10 Sep '14

Hi, I'm using mdbox and replication. Due to configuration error synchronization was not able to be done last week. Since then the problem has been corrected but synchronisation for some mailbox always failed in I/O stalled timeout for 600 seconds. The link between the two servers is quite slow and multiple sync are done in parallel leading to congested link. I can't replicate with rsync as change in the mdbox has been done on the two servers to get back to a working state. What do you think could be done to resynchronized the two dovecot server. Another question is what is this timeout ? Timeout of communication i.e no data received during 600 seconds ( to me that looks unlikely ) or 600 seconds for doing the full sync or 600 seconds for one mail sync. Thanks for any help. Regards, Vincent

preserving flags for shared mailbox when migrating from cyrus to dovecot
by Jogi Hofmüller 10 Sep '14

10 Sep '14

Dear all, Despite all the progress we are making in our attempt to make the migration as smooth and transparent for our users there are still some important unsolved issues. One thing that I can't figure out is how to preserve a user's flags that s/he has for mail in a shared mailbox. So far we tried 'doveadm backup -R' as well as the cyrus2dovecot script from here [1]. Both work well for individual mailboxes but do not migrate subscriptions for shared mailboxes and -- more importantly -- flags for mail in a shared mailbox. Reconstructing subscriptions is quite easy but I have no clue on how to reconstruct a user's flags. Any hint is greatly appreciated!

master user in ldap?
by Francesco 10 Sep '14

10 Sep '14

Hello everyone, i was wondering if it was possible to add master user criteria in ldap backends. the idea is that the users, members of a specific group, should be able to login with their own credentials on behalf of other users. i've tried setting it up like this: hosts = localhost dn = CN=ldapuser,OU=someldapou,DC=domain,DC=tld dnpass = <password> auth_bind = yes ldap_version = 3 base = DC=domain,DC=tld user_attrs = sAMAccountName=home=/var/vmail/% $,skip=found,maxStorage=quota_rule=*:storage=% $M,quota_rule2=Trash:storage=+100M user_filter = (&(ObjectClass=person)(sAMAccountName=% u)(memberOf=CN=Domain Admins,CN=Users,DC=domain,DC=tld)) then i added a passdb as follows passdb { driver = ldap master = yes args = /etc/dovecot/dovecot-ldap-masteruser.conf.ext } and of course the separator. but when i try to login with realuser*userinadministratorsgroup passwordofuserinadministratorsgroup i get authentication failed. am i missing something? is it even possible to accomplish such thing? because i didn't see any example in the wiki, only plain passdb and sql. thanks in advance Francesco

Escape comma in the LDAP passdb subquery configuration
by Francesco Fiore 10 Sep '14

10 Sep '14

Hi I have to configure the LDAP passdb to execute a subquery defining dinamically the new DN to use. For example: pass_attrs = @mail=mail=%{login_user},dc=%{login_domain},dc=example,dc=com,\ =proxy=y,\ =host=%{ldap:mailHost@mail} In the previous example, the problem is the use of "," for DN representation, which is also the separator for the attribute template in the pass_attr parameter value. I tried to escape it with '\' or '%' but it doesn't work. Dovecot version is 2.2.13. How can I resolve this issue? Thanks in advance

ACL with Public Namespace
by Bruno Galindro da Costa 10 Sep '14

10 Sep '14

I've configured a namespace like this: namespace avisos { type = public list = yes location = maildir:/var/mail.avisos:INDEXPVT=~/Maildir/avisos subscriptions = yes prefix = "AVISOS." mailbox DIVULGA { auto = subscribe } } This is the namespace representation in filesystem: root@imap:~# ls -lha /var/mail.avisos/ total 44K drwxr-xr-x 7 vmail mail 4,0K Set 9 18:21 . drwxr-xr-x 16 root root 4,0K Set 9 17:08 .. drwxr-xr-x 5 vmail mail 4,0K Set 9 16:49 .DIVULGA -rw-r--r-- 1 root root 17 Set 9 18:21 dovecot-acl -rw-r--r-- 1 vmail mail 0 Set 9 18:11 dovecot-acl-list -rw-r--r-- 1 vmail mail 360 Set 9 18:11 dovecot.mailbox.log -rw-r--r-- 1 vmail mail 8 Set 9 18:02 dovecot-uidvalidity -r--r--r-- 1 vmail mail 0 Set 9 14:57 dovecot-uidvalidity.540f3f88 -rw-r--r-- 1 vmail mail 249 Set 9 18:11 subscriptions This is the content of dovecot-acl file located at namespace's root level: root@imap:~# cat /var/mail.avisos/dovecot-acl authenticated rs After reload dovecot service, it trows this error message in log: Sep 9 18:14:13 imap dovecot: imap(user@mydomain): Error: Failed to autocreate mailbox AVISOS.DIVULGA: Permission denied So, I've changed the dovecot-acl file to this one and the problem was solved. root@imap:~# cat /var/mail.avisos/dovecot-acl authenticated rsk But that change created another problem: dovecot-acl file is copied into AVISOS.DIVULGA. So, the user can create a maildir inside it. This behaviour is bad because "invalid" maildirs are created under the filesystem. My intention is to don't permit the user to create any maildir inside any location of that namespace. But, I want to make possible to the administrator to edit the dovecot.conf, insert a new mailbox into namespace avisos and reload dovecot service to create new maildirs automatically. How can I solve this problem? -- Att. Bruno Galindro da Costa

Dovecot + Postfix postmulti SASL
by Nerijus Kislauskas 09 Sep '14

09 Sep '14

Hello, Our Postfix setup uses multi-instance feature. I would like to enable dovecot SASL mechanisms in postfix. Open two unix sockets is not a problem for us: service auth { unix_listener /var/spool/postfix-instance1/private/auth { mode = 0660 user = postfix group = postfix } unix_listener /var/spool/postfix-instance2/private/auth { mode = 0660 user = postfix group = postfix } } Lets assume, that postfix-instance1 uses LDAP1, and postfix-instance2 uses LDAP2. How can I use different userdb and passdb databases for those sockets? -- Sincerely, Nerijus Kislauskas

Panic/backtrace in dovecot 2.2.13
by Ed W 07 Sep '14

07 Sep '14

Hi I'm running into regular problems with dovecot choking on "corrupted" index files. The main problem is that it doesn't sort itself out and recover. This message below is repeated regularly in the log files (until I delete the index files) I *think* the trigger to get into this situation might be a files being delivered with incorrect S= values in the filename? Which is to say I am using maildrop to deliver messages and occasionally maildrop seems to write files with incorrect S= names (anyone know why or how to fix it?). The error logged regarding incorrect S= values is obviously completely different, but I speculate that it could be the earlier cause that gets the index file out of shape as shown in the problem here Thanks for any help? (note it's not easy to remove maildrop at present) Ed W Sep 1 07:32:51 mail1 dovecot: imap(xxxxxxx(a)mailasail.com): Panic: file mail-index-transaction-export.c: line 203 (log_append_ext_hdr_update): assertion failed: (u32.offset + u32.size <= ext_hdr_size) Sep 1 07:32:51 mail1 dovecot: imap(xxxxxxx(a)mailasail.com): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x69a9e) [0xedee5a9e] -> /usr/lib/dovecot/libdovecot.so.0(+0x69b21) [0xedee5b21] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0xede97a69] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_transaction_export+0xa36) [0xedfff706] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0xa9f50) [0xedffdf50] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_transaction_commit_full+0xc4) [0xedffe454] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_transaction_commit+0x23) [0xedffe513] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_sync_commit+0xef) [0xee0078ef] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x52e05) [0xedfa6e05] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x52040) [0xedfa6040] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x5251a) [0xedfa651a] -> /usr/lib/dovecot/libdovecot-storage.so.0(maildir_storage_sync_init+0xf4) [0xedfa68d4] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_sync_init+0x3b) [0xedfb786b] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_sync+0x3f) [0xedfb79af] -> dovecot/imap [xxxxxxx(a)mailasail.com 80.189.197.148 SELECT](cmd_select_full+0x187) [0x80594d7] -> dovecot/imap [xxxxxxx(a)mailasail.com 80.189.197.148 SELECT](cmd_select+0x17) [0x8059f37] -> dovecot/imap [xxxxxxx(a)mailasail.com 80.189.197.148 SELECT](command_exec+0x32) [0x805f1a2] -> dovecot/imap [xxxxxxx(a)mailasail.com 80.189.197.148 SELECT]() [0x805e197] -> dovecot/imap [xxxxxxx(a)mailasail.com 80.189.197.148 SELECT]() [0x805e2d9] -> dovecot/imap [xxxxxxx(a)mailasail.com 80.189.197.148 SELECT](client_handle_input+0x115) [0x805e515] -> dovecot/imap [xxxxxxx(a)mailasail.com 80.189.197.148 SELECT](client_input+0x72) [0x805e8c2] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x59) [0xedef8e89] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0xee) [0xedefa05e] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x1c) [0xedef8f1c] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x48) [0xedef8fa8] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x2e) [0xede9d76e] -> dovecot/imap [xxxxxxx(a)mailasail.com 80.189.197.148 SELECT](main+0x2bd) [0x80520ed] -> /lib/libc.so.6(__libc_start_main+0xf5) [0xedce9f25] Sep 1 07:32:51 mail1 dovecot: imap(xxxxxxx(a)mailasail.com): Fatal: master: service(imap): child 31315 killed with signal 6 (core dumps disabled)

lmtp memory usage problem - Fatal: pool_system_realloc(268435456): Out of memory
by Arkadiusz Miśkiewicz 05 Sep '14

05 Sep '14

Hi. In my setup exim delivers mails to dovecot using LMTP. In one LMTP session exim can deliver up to 200 recipients (batch_max set to that value). Now the problem is that sometimes 256MB is not enoug for dovecot lmtp to handle incoming emails. My questions: - how big memory limit should be for lmtp? I was thinking that lmtp (more or less) simply reads from one descriptor and writes to file, then does rename() (maildir used here) and that's all. That shouldn't require big number of memory. So how to determine correct memory limit and what affects this limit? - is number of recipients in one LMTP session important here? Not sure, maybe dovecot stores email in memory first and then writes to the user maildirs? Setting (batch) limit to 1 could reduce memory usage then (since no need to store anything in memory) ? Thanks, Log: Sep 4 16:10:30 mail dovecot: lmtp(21383, user): Fatal: pool_system_realloc(268435456): Out of memory Sep 4 16:10:30 mail dovecot: lmtp(21383, user): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0x682a0) [0x7fe327e632a0] -> /usr/lib64/dovecot/libd ovecot.so.0(+0x6837e) [0x7fe327e6337e] -> /usr/lib64/dovecot/libdovecot.so.0(i_error+0) [0x7fe327e1dbf8] -> /usr/lib64/dovecot/libdovecot.so.0(+0x7d6a3) [0x7fe327e786a3] -> /usr/lib64/dovecot/libdovecot.so.0(i_stream_grow_buffer+0x8f) [0x7fe327e6c4cf] -> /usr/lib64/dovecot/libdovecot.so.0(i_stream_try_alloc+0x82) [0x7fe327e6c592] -> /usr/lib6 4/dovecot/libdovecot.so.0(+0x73b9b) [0x7fe327e6eb9b] -> /usr/lib64/dovecot/libdovecot.so.0(+0x73c36) [0x7fe327e6ec36] -> /usr/lib64/dovecot/libdovecot.so.0(i_stream_read+0x 53) [0x7fe327e6bad3] -> /usr/lib64/dovecot/libdovecot.so.0(+0x77391) [0x7fe327e72391] -> /usr/lib64/dovecot/libdovecot.so.0(i_stream_read+0x53) [0x7fe327e6bad3] -> /usr/lib 64/dovecot/libdovecot.so.0(i_stream_read_data+0x3d) [0x7fe327e6c2fd] -> /usr/lib64/dovecot/libdovecot.so.0(io_stream_copy+0x7f) [0x7fe327e7cacf] -> /usr/lib64/dovecot/libdo vecot.so.0(+0x83310) [0x7fe327e7e310] -> /usr/lib64/dovecot/libdovecot.so.0(o_stream_send_istream+0x4d) [0x7fe327e7c92d] -> /usr/lib64/dovecot/libdovecot-storage.so.0(maild ir_save_continue+0x5a) [0x7fe32811b14a] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_storage_copy+0x88) [0x7fe328145328] -> /usr/lib64/dovecot/libdovecot-storage.so.0 (maildir_copy+0x42) [0x7fe3281179c2] -> /usr/lib64/dovecot/plugins/lib10_quota_plugin.so(+0xb52b) [0x7fe32764352b] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_cop y+0x6d) [0x7fe32814d29d] -> /usr/lib64/dovecot/libdovecot-lda.so.0(mail_deliver_save+0x185) [0x7fe3283f1765] -> /usr/lib64/dovecot/libdovecot-lda.so.0(mail_deliver+0xeb) [0 x7fe3283f1b6b] -> dovecot/lmtp() [0x405d80] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x3f) [0x7fe327e7398f] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handl er_run_internal+0xd7) [0x7fe327e74897] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x9) [0x7fe327e739f9] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x3 8) [0x7fe327e73a78] -> /usr/lib64/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7fe327e22ca3] Sep 4 16:10:30 mail dovecot: lmtp(21383, user): Fatal: master: service(lmtp): child 21383 returned error 83 (Out of memory (service lmtp { vsz_limit=256 MB }, you may need to increase it) - set CORE_OUTOFMEM=1 environment to get core dump) -- Arkadiusz Miśkiewicz, arekm / maven.pl

stemmer or no-stemmer..
by Akash 05 Sep '14

05 Sep '14

Hi, In the documentation of FTS lucene, I need little more clarification about this section: -------------------------------------------------- --with-lucene --with-stemmer The second switch is only required if you have compiled libstemmer yourself or if it's included in the CLucene you are using. -------------------------------------------------- I am totally unsure but as I understand, on Debian testing, the stemmer support for libclucene comes as part of libclucene-contribs1 package (which isn't a required dependency and doesn't get installed if I install dovecot from repos). Please correct me if I am wrong. When I install dovecot-lucene from repos, libclucene-core1 and libstemmer install with it (but no libclucene-contribs1). Does that mean dovecot search has stemmer support? Now I am compiling dovecot and libclucene for Debian stable (which doesn't have latest libs in repos). If I don't compile the contribs part in clucene package but compile dovecot with --with-stemmer, do I get the stemmer support? If I totally opt of this stemmer thing, do I lose anything on search performance? And when you have a no_snowball option, what is the need of libstemmer altogether? Please help me through these confusions.. -Regards, Akash

Migrating from 2.0.x to 2.2
by Jens Dueholm Christensen 05 Sep '14

05 Sep '14

Hi I'm about to migrate a setup with <20 IMAP (but with a few million mails in all) accounts that belong to the same system-user on an older machine running Dovecot 2.0.13 to a new machine running Dovecot 2.2.13 (or possibly newer..). Mails are stored in Maildirs with no special or advanced features (like alternate storage etc etc). Filesystems are prepared for the expected amount of inodes required, and for the time beeing a change to mdbox is seen as an added complexity. One requirement of the migration is that messageID is not changed - mails are referenced by other systems that expect to find individual mails by the ID. Since dsync is incompatible between 2.0<->2.1<->2.2 what is the best way to perform this migration? I was hoping of rsync'ing all Maildirs from the old machine to the new one (including indexes etc etc) and power up Dovecot 2.2.x and see what happens, but is that possible or is there another (and better) way short of installing 2.0.x on the new machine, rsync everything and then upgrade to 2.2.x? Regards, Jens Dueholm Christensen

Trying Dovecot Replication with dsync
by Listas＠Adminlinux 04 Sep '14

04 Sep '14

Hi, I have a failover cluster for mail server with: Ubuntu12.04 + DRBD (for block replication) + Ext4 filesystem + Dovecot-2.0.19-2 with Mdbox It works fine with ~50k accounts. My cluster design: http://adminlinux.com.br/cluster_design.txt I plan to test Dovecot Replication with dsync to build an active/active cluster with load balancing. Can anyone direct me to some literature? A tutorial for example. I'm installing a cluster (for tests) with Ubuntu 14.04 + Ext4 filesystem (without Drbd) + Dovecot-2.2.9-1ubuntu2.1. My conf is in: http://adminlinux.com.br/replication-doveconf.txt I'm following this doc http://wiki2.dovecot.org/Replication but I'm getting some errors: 1) Aug 14 15:39:34 ceph1 dovecot: imap(account=domaintest.com): Error: open(/var/run/dovecot/replication-notify-fifo) failed: Permission denied What is the correct perms for /var/run/dovecot/replication-notify-fifo ?

This one is fairly common: Sep 3 12:58:25 molecular dovecot: dsync-server(user(a)domain.org): Warning: Failed to do incremental sync for mailbox INBOX, retry with a full sync (Modseq 100298 no longer in transaction log) These two I ran into yesterday and today: Sep 2 11:13:32 molecular dovecot: dsync-server(user2(a)domain2.org): Error: Timeout during state=slave_recv_last_common Sep 3 12:52:08 molecular dovecot: dsync-server(user3(a)domain3.org): Error: read(remote.mailserver.net) failed: EOF Configs: mail_plugins = notify replication service doveadm { inet_listener { port = 1234 } } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { mode = 0600 } } service aggregator { fifo_listener replication-notify-fifo { user = vmail mode = 0600 } unix_listener replication-notify { user = vmail mode = 0600 } } plugin { mail_replica = tcp:sub.domain.org:1234 } And doveconf -n: [root@molecular dovecot]# doveconf -n # 2.2.13.16 (94835dd63163): /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-431.el6.x86_64 x86_64 Scientific Linux release 6.5 (Carbon) ext4 auth_mechanisms = plain login auth_verbose = yes auth_verbose_passwords = plain deliver_log_format = msgid=%m: from=%f: %$ doveadm_password = secret doveadm_port = 1234 mail_debug = yes mail_home = /vmail/%d/%n/home mail_location = maildir:/vmail/%d/%n mail_plugins = notify replication 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 namespace { inbox = yes location = prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } plugin { mail_log_fields = box msgid from flags mail_replica = tcp:sub.domain.org:1234 sieve = /vmail/%d/%n/home/.dovecot.sieve sieve_dir = /vmail/%d/%n/home/sieve } protocols = imap pop3 lmtp sieve service aggregator { fifo_listener replication-notify-fifo { mode = 0600 user = vmail } unix_listener replication-notify { mode = 0600 user = vmail } } 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 } unix_listener auth-userdb { mode = 0660 user = vmail } user = root } service doveadm { inet_listener { port = 1234 } } service imap-login { process_min_avail = 3 service_count = 0 vsz_limit = 0 } service managesieve-login { inet_listener sieve { port = 4190 } process_min_avail = 0 service_count = 1 vsz_limit = 64 M } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { mode = 0600 } } ssl_cert = </etc/postfix/ssl/sub.domain.org.pem ssl_key = </etc/postfix/ssl/domain.key userdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } protocol lda { hostname = sub.domain2.org mail_plugin_dir = /usr/lib64/dovecot/ mail_plugins = sieve postmaster_address = postmaster(a)domain2.org } protocol imap { imap_idle_notify_interval = 24 mins mail_max_userip_connections = 60 } protocol sieve { mail_max_userip_connections = 10 managesieve_implementation_string = Dovecot Pigeonhole managesieve_logout_format = bytes=%i/%o managesieve_max_line_length = 65536 } -- --Asai

Insert custom header in Mail logger plugin
by Bruno Galindro da Costa 03 Sep '14

03 Sep '14

Is it possible to log a message custom header through Mail logger plugin or other method? It seems that there are a fixed number of info that is configurable via mail_log_fields (http://wiki2.dovecot.org/Plugins/MailLog) .. My custom header is X-VERTICAL-IP-Quarantine-ID and I want a log event like this one: Aug 27 09:48:13 imap dovecot: imap(user@domain): copy from INBOX: box=SPAM, uid=213, *X-VERTICAL-IP-Quarantine-ID=u7cnUqYDPA9a*, msgid=< 0.0.D7.290.1CFC155CE887302.0(a)etm2.com>, size=26481, vsize=26949, from==?UTF-8?Q?Dafiti=20-=20Parceiros?= <aaa@domain>, subject==?UTF-8?Q?Sapatos=20com=2040%OFF?==?UTF-8?Q?!=20Apro?=? =?UTF-8?Q?veite!?= -- Att.

Setup sieve failed
by Christian Vielhauer 03 Sep '14

03 Sep '14

Hi, I try to setup sieve but I have some trouble. Using dovecot 2.2.9 on Ubuntu 14.04.1 LTS. I replaced my correct domain with „domain.tld“. I am able to create sieve scripts using SOGo. The scripts are created in my mailbox. For example in /var/www/kunden/mail/domain.tld/testuser/sieve/sogo.sieve I have the following script and in same ~/sieve folder is a subdirectory available that’s called "tmp“: ~/sieve ~/sieve/tmp require ["vacation"]; if allof ( not exists ["list-help", "list-unsubscribe", "list-subscribe", "list-owner", "list-post", "list-archive", "list-id", "Mailing-List"], not header :comparator "i;ascii-casemap" :is "Precedence" ["list", "bulk", "junk"], not header :comparator "i;ascii-casemap" :matches "To" "Multiple recipients of*" ) {vacation :days 1 :addresses [„testuser(a)domain.tld"] text: This is a vacation test message. Please ignore. . ; } Now I open /var/log/mail.err and I can see the following: Sep 3 17:50:09 mail dovecot: imap(testuser(a)domain.tld): Error: stat(/var/www/kunden/mail/domain.tld/testuser/.dovecot.sieve/tmp) failed: Not a directory I try to create ~/.dovecot.sieve folder, but this file exists and is a symlink. 0 lrwxrwxrwx 1 vmail vmail 16 Sep 3 18:14 .dovecot.sieve -> sieve/sogo.sieve I think I have some miss configuration because i don’t receive any vacation reply when I send mail to my testuser.

quota for subfolder with prefix=INBOX.
by Jogi Hofmüller 03 Sep '14

03 Sep '14

Hi all, We use prefix=INBOX. in order to keep things as they were on the old server. Now I started playing with quota and have trouble getting the additional quota for Trash and/or Junk working. My expectation was that once a user is over quota and moves email to trash sh/e should be able to receive new email again. That's what I cannot get to work with our setup. Attached you find the config that I thought should be working. The numbers are ridiculously low but that's just for testing. Here is some output from doveadm doveadm quota get -u user Quota name Type Value Limit % User quota STORAGE 5422 5120 105 User quota MESSAGE 18 - 0 doveadm mailbox status -u user "messages vsize" "*" INBOX messages=13 vsize=3147033 doveadm mailbox status -u user "messages vsize" "INBOX.*" INBOX.Drafts messages=0 vsize=0 INBOX.Sent messages=0 vsize=0 INBOX.Trash messages=5 vsize=2475790 INBOX.Junk messages=0 vsize=0 Regards, -- j.hofmüller We are all idiots with deadlines. - Mike West

Trouble viewing Inbox via IMAP Client
by Peter Cook 02 Sep '14

Hello, I have been having trouble with this issue for quite some time now. Here is my environment: CentOS 6.5, Postfix built with PGSQL support, PFA, and dovecot.

dsync-server couldn't create .dovecot-sync.lock file

My dovecot stores users' emails on /var/spool/imap/<user> and stores the messages index on /var/lib/imap/<user>. I have many users who do not yet have their userdb_home directories created on the server, because that is created at the time of first login. I'm testing dsync for replication and have seen the following error: dsync-server(<user>): Error: Couldn't create lock /var/lib/imap/<user>/.dovecot-sync.lock: No such file or directory The /var/lib/imap/<user> directory does not exist yet and I think this is the cause.

mail_location hashing & lowercasing?

31 Aug '14

Currently, I'm using mail_location = mdbox:/var/spool/mail/%Ld/%Ln/mdbox Now I want to add a partitioning (so I don'T have all directories in one single directory), but can't find the right syntax: mail_location = mdbox:/var/spool/mail/%Ld/<HASHING HERE>/%Ln/mdbox It seems like I'd need to use %N (new hash) on %Ln and then take a substring of that. %2NLn 2 Characters of the %N hash of %Ln (the lowercase username) But this gives me a verbatim "Ln" on the path! -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein

Need help to compile and install a minimal dovecot imap plugin
by Stefan Arentz 31 Aug '14

31 Aug '14

I am trying to create a plugin that adds a new IMAP capability. So far I have this: const char *foo_plugin_version = DOVECOT_ABI_VERSION; static struct module *foo_module; static imap_client_created_func_t *next_hook_client_created; static void foo_client_created(struct client **client) { str_append((*client)->capability_string, " XFOO"); if (next_hook_client_created != NULL) { next_hook_client_created(client); } } void foo_plugin_init(struct module *module) { i_info(“init”); foo_module = module; next_hook_client_created = imap_client_created_hook_set(foo_client_created); } void foo_plugin_deinit(void) { i_info(“deinit”); imap_client_created_hook_set(next_hook_client_created); } const char foo_plugin_binary_dependency[] = "imap”; On Fedora 20, with the dovecot and dovecot-devel packages installed, I compile this with: cc -Wall -shared -fPIC -DHAVE_CONFIG_H -I/usr/include/dovecot -o lib20_foo_plugin.so foo-plugin.c And then install with: sudo cp lib20_foo_plugin.so /usr/lib64/dovecot/ (I also have mail_plugin_dir = /usr/lib64/dovecot in 10-mail.conf) I enable this plugin in /etc/dovecot/conf.d/20-imap.conf with: protocol imap { mail_plugins = $mail_plugins foo } But … nothing happens. No warnings, no errors, no crashes. How do I debug this? Am I missing something obvious? Does the naming of the plugin matter? S.

Misleading error message when case-insensitive file/dir names from config files clash with case-sensitive file system.
by Info Akra 30 Aug '14

30 Aug '14

Hi, Is it noted somewhere that Dovecot (v 2.0.9) doesn’t use case in directory names in its config-files? I found that out the hard way (i.e. a week of debugging)!! in /etc/dovecot/conf.d/10-master.conf, the line: unix_listener /var/spool/postOut/auth/dovecot-auth { creates a: Jul 29 22:15:58 server dovecot: master: Error: service(auth): unlink(/var/run/dovecot/) failed: Is a directory but unix_listener /var/spool/postout/auth/dovecot-auth { works just fine (with matching case changes on the directory names themselves). That’s on running on Ubuntu 12.04.4 TLS, standard installation from apt-get, in cooperation with Postfix 2.0.9. — Hugo

Dsync setup... help needed
by Sinergizmas Sin ergizmas 30 Aug '14

30 Aug '14

Hello, I tried to implement Dsync (doveadm version 2.2.10) following https://www.evilcoder.org/2014/08/22/automatic-replication-with-dovecot/ but had no luck. SSH commands working quite well, but I need to respond more quickly. So TCP looks promising. I have Centos 6, Dovecot 2.2.10. I did everything that is written there, but after I restart dovecot doesn't sync. Then i ran netstat command but no service listen to port 12345 also. Iptables service are of in testing scenario...

Hi, i want to migrate the following setup: postfix / courier-{imap/s,pop3/s,authlib} / maildrop / mysql I´m using the maildir format and quotas as well. My target is the following setup: postfix / dovecot / some sort of quota respecting lda / mysql What i`ve done already: SQL-Implementation for dovecot, login process and also sending mails via auth-userdb is already working. Quotas are read out from database and working. Before i mention my problems while implementing, here is the config im using at this time: # 2.2.13: /etc/dovecot/dovecot.conf # OS: Linux 3.14.14-gentoo x86_64 Gentoo Base System release 2.2 auth_mechanisms = plain login auth_socket_path = /var/run/dovecot/auth-userdb auth_verbose = yes disable_plaintext_auth = no info_log_path = syslog login_log_format_elements = user=<%u> method=%m ip=%r mpid=%e mail_debug = yes mail_location = maildir:.maildir mail_plugins = quota namespace inbox { inbox = yes location = .maildir 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 = . } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { args = /etc/dovecot/dovecot-sql.conf.ext quota = maildir:User quota quota_rule = %u quota_rule2 = trash:storage=+150M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u } service auth { unix_listener /var/spool/postfix/private/auth { group = mail mode = 0660 user = postfix } unix_listener auth-userdb { group = mail mode = 0660 user = postfix } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0666 user = postfix } } ssl_cert = </etc/ssl/dovecot/server.pem ssl_key = </etc/ssl/dovecot/server.key userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota } grep -v '^ *$#.*$\?$' dovecot-sql.conf.ext driver = mysql connect = host=127.0.0.1 dbname=postfix user=postfix password=thereisone default_pass_scheme = MD5-CRYPT password_query = \ SELECT username, password \ FROM mailbox WHERE username = '%u' user_query = \ SELECT concat('/', home, user, '/', destinationname) AS home, uid, gid, \ concat('*:storage=', round(quota / 1000 * 1.024)) AS quota_rule \ FROM mailbox WHERE username = '%u' Where user is the row where the admin-panel user is stored and username is the mbox-user. My problem is the LDA, with dovecot-lda im having the uid / gid trouble and i really dont want to suid oder sudo it. dovecot-lmtp just gives me status=deferred (host xx.xx[/var/run/dovecot/lmtp] said: 451 4.3.0 <box(a)xx.xx> Temporary internal error (in reply to end of DATA command)) Postfix virtual is working as well as maildrop, but no dovecot-implementation wants to, i also didnt find anything about the error above, except a bug in v2.2.2 and a google groups thread where users are just blaming each others for nothing .. I want to use a dovecot lda/lmtp because the quota settings for trash-folders are very nice and reducing my support times but im stuck at getting one of the dovecot-LDAs to work. Let me know if you need any additional information. Any help is greatly appreciated! -- Viele Grüße / Best regards Patrick

Multiple A Records for IMAP service
by Vijay Rajah 29 Aug '14

29 Aug '14

Hello All, I have a quick question. I have 2 MX servers each with a Dovecot Instances (2.2.6). These 2 Dovecot Instances are replicated by using Dsync... All works well. The questions is, Can I have 2 A records for my imap.mydomain.tld? The Idea being, if for any reason, one of the Dovecot IMAP instances are unreachable, the client can connect to the other Instance. (this is purely a fail over scenario). If it matters, The clients are Thunderbird, Android Native (default) Mail client, iOS Mail Client. -Thanks in advance Vijay

Documentation for /usr/lib/dovecot/imap executable
by Christoph Groth 29 Aug '14

29 Aug '14

Dear Dovecot experts, I'm in the process of setting up dovecot with mbsync as a local cache for remote IMAP servers. One recipe that I found involves using the /usr/lib/dovecot/imap (This is with Debian's dovecot package). For example, in .mbsyncrc I have IMAPAccount cwg-wf-local RequireSSL no Tunnel "/usr/lib/dovecot/imap -o mail_location=maildir:/home/cwg/.mail/cwg-wf" This works, but I wonder: is there any documentation for the /usr/lib/dovecot/imap executable? What options does it take? If there's no documentation: where can I find this command in dovecot's sources? Thank you, Christoph

Postfix + dovecot setup
by Timothy Murphy 29 Aug '14

29 Aug '14

I'm trying to clarify the various ways in which I could set up Postfix + Dovecot + SpamAssassin under CentOS-7, and I'd welcome any comments on the following remarks. As far as I can see there are 3 standard ways of setting this up: 1. Use amavisd 2. Use dovecot + pigeonhole/sieve 3. Use spamass-milter At present I'm following (2), but am thinking of going over to (1), since this seems simpler. (Amavisd wasn't available when I set up CentOS-7, so I didn't consider it then.) It seems to me that (2) is using dovecot in a slightly odd way, since as far as I can see dovecot normally takes email from ~/Maildir/cur/ and then moves marked spam. I'm not quite sure if (3) is a genuine alternative, or if it is why it is not the standard? -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

Hi all! Does dovecot cluster (with Proxy/Director) work only distributed filesystems (like NFS) ? Is Dovecot-replication + Ext4 recommended for production environments? Thanks! -- Thiago Henrique

POP/IMAP HA solution for 5k users
by Sinergizmas Sin ergizmas 28 Aug '14

28 Aug '14

Hello, I want to build simple, cheap HA solution for 5000 users with postfix/dovecot. Each user will have 1.3 GB mailbox (maildir) storage quota. All of the users will use POP and also plus half of them will use IMAP from smart phones. Sometimes they will hit webmail (squirrelmail). I plan that every user will send 20 and receive 20 mails per day. I have 3 locations, but electricity are not very stable there. We have outages for couple of hours 3-4 times per year. So I plan distribute all servers (it's more like good PC's) across locations. I'm very tied on budget also. Or maybe I could say I don't have it and I'm forced to use hardware equipment which is given. We are talking about quite pour HA solution here. Don't judge me please. I start to plan architecture and I would be very thankful for all your thoughts. I'm not expert in this area, but I need to learn, fire up email system and manage it. I will have SMTP server (smtp.example.com) which will filter mail with Clam, Spamassasin, Greylisting and forward emails to IMAP/ POP3/webmail server (mail.example.com) Mail.example.com will sync all user and mail changes to the third server mail2.example.com. Mail2.example.com server is just stand by, hot backup server in cases if main mail server or smtp will not be reachable. Locations of servers are in different cities: Locations #1 - SMTP servers as virtual machines (vmware server or virtualbox), with CPU i3, 6GB RAM, SSD, Centos 6, Virtualmin Location #2 - Dovecot/webmail server: CPU i5, 16GB RAM, HDD 1SSD for OS/dovecot indexes and SATA 2TBx4 LVM (total 8TB) for Maildir's, Centos 6, Virtualmin Location #3 HOT BACKUP (always online) server in case of mail.example.com or smtp.example.com failure, electricity outage and etc. It contains Dovecot/webmail server: CPU i3, 8GB RAM, HDD 1SSD for OS/dovecot indexes and SATA 2x4TB LVM (total 8TB), Centos 6, Virtualmin DNS configuration (and location number): IN MX 10 smpt.example.com. (#1) IN MX 20 mail.example.com. (#2) IN MX 30 mail2.example.com. (#3) .... smtp IN A aa.aa.aa.aa mail IN A bb.bb.bb.bb mail2 IN A cc.cc.cc.cc So I need to solve SMTP, POP, IMAP high availability tasks. SMTP I think will be ok for external users. SMTP feature has all three servers. If smtp.example.com server is offline mail is sent to mail.example.com If mail.example.com is offline, then mail is sent to mail2.example.com If mail2.example.com is offline, the senders SMTP server will hold an email in a queue by default for 3 days (in most cases) and will try to deliver in some intervals. Local (users of domain example.com) SMTP/POP/IMAP users will have problems, because their domain server will be dead. This means that connections from user MTA agents (outlook POP) could not be delivered because DNS A type record pointing to a degraded server. When problem with server mail.example.com (POP/IMAP/webmail) connectivity will happen, I think to login to DNS server and point record (A type) to a working server. So if server in location #2 mail.example.com is dead, I will change mail IN A bb.bb.bb.bb ----> cc.cc.cc.cc The same with the server smtp.example.com. If it's down, I will change mail IN A aa.aa.aa.aa ----> cc.cc.cc.cc I know that this method is not perfect because of ISP DNS caching around the globe, but this the only option I have. Most of my users use ISP that refresh DNS in a period of 30 minutes so it won't be very terrible to half of hour to wait for the connection. My questions: 1. Is this infrastructure is ok for 5000 users? If you think it's not, please write how many users it will serve "normally"? Or maybe I it could handle and 10 000 users load? 2. Is the logic of all setup is right in such situation like mine? What other problems could arise? 3. I prefer to create users from one server. So the LDAP option is the best for me? In case of LDAP it will be on server #2 and I need to replicate it to #3. Is it rigth? Then server #2 will be offline does #3 LDAP will take place? Or should I better use batch command to create user in each server per single command? Actually I do not want to manage and LDAP as extra service. I don't have experience with it. 4. The main problem is to synchronize maildir of POP/IMAP/webmail servers. Because of distance I do not want to use DRBD. It's not suitable for WAN connections. GlusterFS seems an option but.. I saw on internet users also having problems with it performance. Sometimes gluster hang and all cluster must be restarted. Maybe I can sync /home with gluster where maildir resides, but we need to take care of dovecot index and control files synchronization also. The performance of retrieving index'es by several thousands users every 2-5 minutes must be excellent. The only option I found is Dovecot Dsync (or newer Doveadm) command. I made initial tests on two servers, but only to get work with SSH command. The method using TCP connection doesn't work for me. So question, if I use SSH method in several thousand user system does it cause me trouble? SSH adds some overhead comparing to TCP. But could make a permament tunnel and TCP also would be quite secure. So please tell me what methods are you using to sync two mail servers (especially for POP accounts) in different locations? 5. File system. Is it ok to use EXT4 file system? I know that XFS is better in performance working with small files (maildir = a lot of small files), but in power outage it can become corrupted without journal. Thanks.
