Corrupted dbox file around offset= EOF reading msg header
by DurgaPrasad - DatasoftComnet 02 May '18

02 May '18

Hello Dovecoters, I am using dovecot-2.2.10-8.el7.x86_64 on RHEL 7.4 When I backup mdboxes (using SIS) using this command doveadm -Dv -o plugin/quota= sync -1f -u user1(a)user.com mdbox:/mailbackup/user1 mails get backedup but all m files are not copied. Last file copied is m.4 If I run the command again I get below error I tried with doveadm backup command as well (many times). Error: Corrupted dbox file / mailbackup/user1/storage/m.4 (around offset=3732536): EOF reading msg header (got 0/30 bytes) Result is all mails are not backedup. Destination is a folder on a NAS with NFS mapped to the server. Thanks/DP --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

Panic when using doveadm fts lookup
by André Rodier 29 Apr '18

Hello, I am actually testing dovecot fts search, using doveadm fts lookup. I run this command: doveadm fts lookup -u andre subject "Test" And this generate this error: doveadm(andre): Panic: file mail-storage.c: line 1694 (mailbox_get_open_status): assertion failed: (box->opened) doveadm(andre): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x95e92) [0x7fa7ac9e8e92] -> /usr/lib/dovecot/libdovecot.so.0(+0x95f19) [0x7fa7ac9e8f19] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7fa7ac97ea91] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_get_open_status+0x68) [0x7fa7accb5f68] -> /usr/lib/dovecot/modules/lib21_fts_solr_plugin.so(+0x494d) [0x7fa7ab90394d] -> /usr/lib/dovecot/modules/lib20_fts_plugin.so(fts_backend_lookup+0x4d) [0x7fa7abf6861d] -> /usr/lib/dovecot/modules/doveadm/lib20_doveadm_fts_plugin.so(+0x2821) [0x7fa7aabff821] -> doveadm(+0x28fcd) [0x5617545e8fcd] -> doveadm(+0x29ba8) [0x5617545e9ba8] -> doveadm(doveadm_cmd_ver2_to_mail_cmd_wrapper+0x21c) [0x5617545ea9ec] -> doveadm(doveadm_cmd_run_ver2+0x555) [0x5617545f9d25] -> doveadm(doveadm_cmd_try_run_ver2+0x37) [0x5617545f9d77] -> doveadm(main+0x1da) [0x5617545d9afa] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf1) [0x7fa7ac5d42e1] -> doveadm(_start+0x2a) [0x5617545d9eda] Do I have to do anything special to test the dovecot fts index with doveadm lookup?

Listening on multiple ports
by Derek Harding 28 Apr '18

28 Apr '18

Hi, I want dovecot to listen for imaps (ssl) on both 993 and a non-standard port 8839. I've tried using variations on the inet_listener entries in 10-master.conf as shown in a couple of threads on here but none of the attempts have worked. Can someone provide me with a cut-and-paste solution and confirm into which file it should be placed (i.e. is the dovecot.conf format using the inet_listener = {address} appropriate)? -- Best wishes, Derek

Virtual mailbox doesn't refresh without deleting indexes
by Bret Martin 26 Apr '18

26 Apr '18

Hello, I have a virtual mailbox with the following dovecot-virtual file: mdbox/* -mdbox/Archive/* -mdbox/Junk -mdbox/Notes all younger 604800 not deleted This works at first, but after messages are older than 7 days, they continue to appear in this mailbox forever. Even if I close all IMAP clients and reconnect, I can't get the mailbox to omit the older-than-7-days messages without deleting its indexes. I have other virtual mailboxes that update as expected, but I don't think any of those are date-based. For example, this one "refreshes" as I'd expect: mdbox/* -mdbox/Archive/* -mdbox/Junk flagged Am I doing something wrong with the first virtual mailbox I mentioned above? I'm using dovecot 2.2.13 on Debian GNU/Linux. Thanks! --Bret

director stuck in inifite loop on 2.2.35
by Jan-Pieter Cornet 26 Apr '18

26 Apr '18

Occasionally, all of our directors get stuck in an endless loop. Likely triggered by some network event, but I haven't been able to isolate exactly what triggers it, and am unable to reproduce at the moment. When this happens, it makes the dovecot/director process on all directors unresponsive, making login impossible. Restarting dovecot "fixes" it. Here's the info collected from the stuck process. I hope that a dovecot dev could use this to either fix a bug in the async IO code or point to a possible external source that could have triggered this. Would it help to compile dovecot with -g and run a version with debugging info, to be able to inspect more when the crash happens again? "strace" showed this endless loop: 09:27:52.837960 epoll_ctl(14, EPOLL_CTL_DEL, 213, 0x7ffe8e642cdc) = 0 09:27:52.837993 epoll_ctl(14, EPOLL_CTL_ADD, 213, {EPOLLIN|EPOLLPRI|EPOLLERR|EPOLLHUP, {u32=3317538000, u64=94320799358160}}) = 0 09:27:52.838035 epoll_ctl(14, EPOLL_CTL_DEL, 213, 0x7ffe8e642cdc) = 0 09:27:52.838070 epoll_ctl(14, EPOLL_CTL_ADD, 213, {EPOLLIN|EPOLLPRI|EPOLLERR|EPOLLHUP, {u32=3317538000, u64=94320799358160}}) = 0 "ltrace" showed the same loop as: 10:38:01.773867 timeout_add(0x7530, 0x55c8c351df75, 965, 0x55c8c3515a00) = 0x55c8c5c658b0 10:38:01.774060 timeout_remove(0x55c8c5acf7a8, 0, 0xffffffff, 0) = 0 10:38:01.774239 io_add(213, 1, 0x55c8c351df75, 1070) = 0x55c8c5c658b0 10:38:01.774429 io_set_pending(0x55c8c5c658b0, 1, 0x55c8c54b8aa0, 0x7fb4ab11b06a) = 0x55c8c54b8aa0 10:38:01.774598 p_strarray_dup(0x7fb4ab703660, 0x55c8c5786e00, 5, 0x55c8c3723740) = 0x55c8c56d7530 10:38:01.774771 io_remove(0x55c8c5acf788, 0x55c8c3516d60, 5, 48) = 0 10:38:01.774957 timeout_add(0x7530, 0x55c8c351df75, 965, 0x55c8c3515a00) = 0x55c8c5c658b0 10:38:01.775129 timeout_remove(0x55c8c5acf7a8, 0, 0xffffffff, 0) = 0 10:38:01.775301 io_add(213, 1, 0x55c8c351df75, 1070) = 0x55c8c5c658b0 10:38:01.775492 io_set_pending(0x55c8c5c658b0, 1, 0x55c8c54b8aa0, 0x7fb4ab11b06a) = 0x55c8c54b8aa0 10:38:01.775662 p_strarray_dup(0x7fb4ab703660, 0x55c8c56d7530, 5, 0x55c8c3723740) = 0x55c8c5786e00 10:38:01.775833 io_remove(0x55c8c5acf788, 0x55c8c3516d60, 5, 48) = 0 That fd 213 is the next-highest FD opened, and is bound to /var/run/dovecot/director-admin.

replication and .dovecot.lda-dupes
by Patrick Cernko 25 Apr '18

25 Apr '18

Hi list, this question was already posted a few years ago (https://www.dovecot.org/list/dovecot/2014-November/098585.html) I already asked the original queriest and he told me, that he never got an solution or workaround but it was not important enough for him. When using replication in conjunction with sieve vacations, the .dovecot.lda-dupes file is not synced with the other server. So when delivering to both servers (round-robin or randomized), senders might get more vacation mails than configured as the other server does not know, that the first one already sent a vacation message. Is this a bug or intentional? If it is a bug, I hereby ask for a fix, please. We are using Dovecot version 2.2.27 on Debian/stretch. This is dovecot -n (hostnames anonymized): # 2.2.27 (c0f36b0): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.16 (fed8554) # OS: Linux 4.9.76.1.amd64-smp x86_64 Debian 9.3 auth_verbose = yes default_vsz_limit = 2 G doveadm_password = # hidden, use -P to show it doveadm_port = 12345 listen = * login_log_format_elements = pid=%p user=<%u> method=%m rip=%r lip=%l mpid=%e %c mail_attachment_dir = /IMAP/mail/attachments mail_attachment_fs = sis-queue /IMAP/mail/attachments/queue:posix mail_home = /IMAP/mail/mailboxes/%u mail_location = mdbox:~/mdbox mail_log_prefix = "%s(%u[%p]): " mail_max_userip_connections = 0 mail_plugins = " notify replication zlib fts fts_squat" maildir_stat_dirs = yes 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 { 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 = } passdb { args = /etc/dovecot/ldap.conf driver = ldap } plugin { fts = squat fts_autoindex = yes fts_squat = partial=4 full=10 mail_replica = tcp:other-server sieve = file:~/sieve;active=~/.dovecot.sieve zlib_save = gz zlib_save_level = 3 } postmaster_address = <> protocols = " imap lmtp sieve" service aggregator { fifo_listener replication-notify-fifo { mode = 0666 } unix_listener replication-notify { mode = 0666 } } service anvil { client_limit = 2250 } service auth { client_limit = 2447 } service doveadm { inet_listener doveadm-server { port = 12345 } } service imap-login { inet_listener imap { port = 0 } process_limit = 2047 } service imap { process_limit = 2047 } service lmtp { inet_listener lmtp { port = 24 } } service pop3-login { inet_listener pop3 { port = 0 } inet_listener pop3s { port = 0 } } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { mode = 0666 } } ssl_cert = </etc/ssl/certificate.pem ssl_key = # hidden, use -P to show it userdb { args = /etc/dovecot/userdb.overrides driver = passwd-file } userdb { args = /etc/dovecot/ldap.conf driver = ldap } verbose_proctitle = yes protocol lmtp { auth_username_format = %n mail_plugins = " notify replication zlib fts fts_squat sieve" } protocol lda { mail_plugins = " notify replication zlib fts fts_squat sieve" } And this is /etc/dovecot/ldap.conf (hostnames anonymized): uris = ldaps://ldap1/ ldaps://ldap2/ base = dc=domain user_filter = (&(objectClass=posixAccount)(uid=%u)) user_attrs = \ =user=%{ldap:uid}, \ =uid=%{ldap:uidNumber}, \ =gid=%{ldap:gidNumber} pass_filter = (&(objectClass=posixAccount)(uid=%u)) iterate_filter = (&(objectClass=posixAccount)(istMailHomeServer=servername)) auth_bind = yes /etc/dovecot/userdb.override is currently an empty file. P.S.: Although I do not think, that this has something to do with our problem, I should mention that we run SIS with system uids.

dovecot HA setup across large geographic distances
by Sophie Loewenthal 24 Apr '18

24 Apr '18

Hi, I have a working postfix/dovecot config on Debian located in Europe[EU]. I would like to provide either an HA/load balanced setup with a second site in Australia[AU] because of users located between EU/Asia/AU. The site to site traffic would be tunneled through either SSH or a VPN * Has this been done with Doevcot over such great distances? * How can the delay between mailstore synchonisation be handled? ( Currently looking for an opensource product like Netex's HyperIP) I'd be grateful for your thoughts. Best wishes, Sophie Sent from a phone, thus brief.

Pass UniqueID to sieve scripts
by Peter Blok 24 Apr '18

24 Apr '18

Hi, If a user moves a mail to a Junk folder, this e-mail is going thru imap_sieve and ends up in sa-learn. I wrote some tools to immediately propagate that to the other node of the cluster as well as locally. Everything works fine, but sometimes I see a storm of requests hogging the CPU and I would like to collect some debugging information, Preferably I would like the permanent unique id of the mail in the maildir, but am looking for some kind of unique id that will help me identify if an e-mail somehow passes the sieve filter multiple times. Basically I have changed the pipe to sa-learn to my proxy that will send it across to the other node as well as call sa-learn locally. So something I can get in a sieve script and pass along. Peter

Sieve "redirect" changes envelope sender in 2.3. / pigeonhole 0.5
by Olaf Hopp 24 Apr '18

24 Apr '18

Hi (Stephan?), is it a new feature of dovecot 2.3 /pigeonhole 0.5 that a sieve "redirect" changes the envelope sender of a redirected mail or simply a bug ? A sends mail to B, B redirects to C C sees B (not A!) as envelope sender. It is not a problem if C gets the mail but if that mail bounces for various reasons it goes back to B and A will never know about this. I thick this is came with 2.3 / pigeonhole 0.5 ? # 2.3.1 (c5a5c0c82): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.devel (61b47828) # OS: Linux 2.6.32-696.23.1.el6.x86_64 x86_64 CentOS release 6.9 (Final) Regards, Olaf -- Karlsruher Institut für Technologie (KIT) ATIS - Abt.

dovecot vs. mutt: no full index sync on Maildir new/ mtime change
by Michael Büker 24 Apr '18

24 Apr '18

Hi, everyone! This is a follow-up to "Looks like a bug to me: Dovecot ignores Maildir/new timestamp" from Fredrik Roubert on 01.12.2015: https://www.dovecot.org/list/dovecot/2015-December/102585.html I've run into the same problem as Fredrik: When manipulating my Maildir locally with mutt, deleting a message from new/ doesn't cause a full update of the index. Therefore, IMAP clients still see the deleted message. I've read and understood Timo's reply saying that dovecot only performs a "partial sync" of the index when the mtime of new/, but not of cur/, changes. This makes perfect sense for performance reasons for most users: https://www.dovecot.org/list/dovecot/2015-December/102588.html I, however, would be willing to take the performance hit of a full index sync whenever the mtime of new/ changes. Therefore, I looked at the code and tried to implement a config option (maildir_fullsync_on_new_mtime_change) for this behavior. However, my understanding of src/lib-storage/index/maildir/maildir-sync.c was not good enough – I probably put the ctx->mbox->storage->set->maildir_fullsync_on_new_mtime_change check in the wrong place, and all my patch did was ruin the index ;) So, to summarize my question: I'd like dovecot to perform a full index sync when the mtime of a Maildir's new/ has changed. I'm willing to take the performance hit, because it would fix a problem I'm having with using mutt and dovecot together. Can this be done in principle by adding a config option check like ctx->mbox->storage->set->maildir_fullsync_on_new_mtime_change in the right place in src/lib-storage/index/maildir/maildir-sync.c? If so, where should it be put? Thanks for your time, Michael

smtp crashing with "out of memory" for ONE particular user

Hi, I’m using dovecot 2.0.16 (I know, it’s oooold, but I have too many users to risk the upgrade while so many things have changed since) and virtual users based on MySQL. Today I had some troubles with user, who’s mailbox stopped working. No emails were delivered, with just following error line in EXIM mainlog: LMTP connection closed after end of data When I checked dovecot’s main log, and here’s what I found: Apr 23 14:06:17 lmtp(9963, jmk(a)silvercube.pl) Fatal: block_alloc(67108864): Out of memory Apr 23 14:06:17 lmtp(9963, jmk(a)silvercube.pl) Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0x3dbda) [0x7f92f3193bda] -> /usr/lib64/dovecot/libdovecot.so.0(+0x3dc1e) [0x7f92f3193c1e] -> /usr /lib64/dovecot/libdovecot.so.0(i_error+0) [0x7f92f316d8cd] -> /usr/lib64/dovecot/libdovecot.so.0(+0x4cc45) [0x7f92f31a2c45] -> /usr/lib64/dovecot/libdovecot.so.0(+0x4cc7f) [0x7f92f31a2c7f] -> /usr/lib64/ dovecot/libdovecot.so.0(p_strdup+0x3e) [0x7f92f31ae08e] -> /usr/lib64/dovecot/libdovecot-storage.so.0(maildir_uidlist_sync_next_uid+0xf9) [0x7f92f3653e69] -> /usr/lib64/dovecot/libdovecot-storage.so.0(ma ildir_uidlist_sync_next+0x12) [0x7f92f3654232] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x6bd3a) [0x7f92f3651d3a] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x6c7d3) [0x7f92f36527d3] -> /usr/li b64/dovecot/libdovecot-storage.so.0(maildir_storage_sync_init+0x171) [0x7f92f3652d91] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_sync_init+0x31) [0x7f92f36173a1] -> /usr/lib64/dovecot/libdovec ot-storage.so.0(mailbox_sync+0x27) [0x7f92f36174b7] -> /usr/lib64/dovecot/plugins/lib10_quota_plugin.so(quota_count+0x132) [0x7f92f1f34fe2] -> /usr/lib64/dovecot/plugins/lib10_quota_plugin.so(+0x8430) [0 x7f92f1f36430] -> /usr/lib64/dovecot/plugins/lib10_quota_plugin.so(+0x863d) [0x7f92f1f3663d] -> /usr/lib64/dovecot/plugins/lib10_quota_plugin.so(quota_get_resource+0x72) [0x7f92f1f344c2] -> /usr/lib64/do vecot/plugins/lib10_quota_plugin.so(quota_test_alloc+0x175) [0x7f92f1f34d45] -> /usr/lib64/dovecot/plugins/lib10_quota_plugin.so(+0xb0ba) [0x7f92f1f390ba] -> /usr/lib64/dovecot/libdovecot-storage.so.0(ma ilbox_save_begin+0x46) [0x7f92f3617f56] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_storage_copy+0x7e) [0x7f92f361100e] -> /usr/lib64/dovecot/libdovecot-storage.so.0(maildir_copy+0x51) [0x7f92f364 a8a1] -> /usr/lib64/dovecot/plugins/lib10_quota_plugin.so(+0xaefa) [0x7f92f1f38efa] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_copy+0x5a) [0x7f92f3617eba] -> /usr/lib64/dovecot/libdovecot-siev e.so.0(+0x36ed6) [0x7f92f1ae9ed6] -> /usr/lib64/dovecot/libdovecot-sieve.so.0(+0x2d83c) [0x7f92f1ae083c] -> /usr/lib64/dovecot/libdovecot-sieve.so.0(sieve_result_execute+0x2fd) [0x7f92f1ae1a0d] -> /usr/l ib64/dovecot/libdovecot-sieve.so.0(sieve_execute+0x7d) [0x7f92f1af0a9d] Apr 23 14:06:17 master: Error: service(lmtp): child 9963 returned error 83 (Out of memory (vsz_limit=256 MB, you may need to increase it)) What was interesting - it happenned only with this particular mailbox.

question about using cram-md5 login passwords
by Fabian A. Santiago 23 Apr '18

23 Apr '18

hello dovecot community, question; if my user database and dovecot installation is currently setup to use plain login passwords, and i want to convert to cram-md5, after i configure dovecot accordingly and reset passwords into cram-md5, if anyone uses plain login method again in the future, will it still work? or must they always from this point on use encrypted passwords? Thanks. -- Thanks, Fabian S. OpenPGP: 0x643082042DC83E6D94B86C405E3DAA18A1C22D8F (new key) 0x3C3FA072ACCB7AC5DB0F723455502B0EEB9070FC (to be retired / revoked)

lost connection while sending end of data error
by Christos Chatzaras 23 Apr '18

23 Apr '18

I use dovecot-lmtp and postfix. When I send e-mail to 2 recipients (or more) at the same time and if one of them is over quota (or under quota and the message I send is bigger than his free space) mailq shows: -Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient------- 20B03336F22 26099 Thu Apr 19 18:02:47 support(a)example.com (lost connection with server25.example.org[private/dovecot-lmtp] while sending end of data -- message may be sent more than once) user1(a)example.com user2(a)example.com E-mails sent from the same domain on same server so it's a local delivery. If I send the e-mail to the over quota user ( only him on To: ) then I get a bounce that says that user is over quota which is the correct behaviour. I think the problem started after I upgrade dovecot-2.2.35 to dovecot-2.3.1. Is this a known bug?

2.3.1 -> "doveadm backup -A" not working
by spamvoll＠googlemail.com 21 Apr '18

21 Apr '18

Hi, I'm running 2.3.1 and trying to do a backup. Wiki and manpage showes that -A will backup all mailboxes. It seems that "doveadm -Dv backup -A mdbox:/mnt/BACKUP/DOVECOT/" is saving each mailbox to " /mnt/BACKUP/DOVECOT/" but after finishing one, its overwriting the data from the previous user. So it ends with only the mails from the last user processed. I tried %u but thats not recognized and used as String in the path. Hans

If you are doing this backup with a fully operational mail storage: no, it won't. The reason is quite simple: mdbox saves the data of an email in several files, so there's a good chance that those files might slightly change during backup, while with Maildir all necessary data for the restore is stored in the file names. If you want to do a consistent backup, you do need file system snapshots and should make sure that this snapshot is consistent or to turn off the mail store during backup completely. But just doing rsync on the fly as with Maildir is just begging on your side to run into problems sooner or later... -- Greetings, Marc --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

maildir vs dbox?

Hello, I've got a Dovecot virtual email setup using maildir as the mailbox format. I am wondering from others who have chosen dbox a comparison between maildir and dbox or those who have migrated from one format to another. I am wondering if changing to dbox would be beneficial? Thanks. Dave.

Replication between servers with different mail_home path
by Arie Peterson 19 Apr '18

19 Apr '18

Hi, I have two dovecot servers that are configured to be replicated using dsync over ssh. This has been working well for a long time. Recently I changed the mail_home path on one of the servers, because of mail data migration. The old file system is still available, but has been made read-only for now – I plan to remove it once everything runs smoothly again. Now it seems replication is failing: the mail.err log file on both servers has lots of error messages saying that it tried to open a file on the old location and failed because it is read-only. Is this setup, with different mail_home paths on the two servers being replicated, even supported? If so, do I need to specify this explicitly in the configuration? I couldn't find relevant settings in the documentation.

Comparing Indexing Speed + ZFS question
by Qmail 18 Apr '18

18 Apr '18

Hi, have two quick questions: I am re-indexing some large mailboxes and I wanted to get some opinions on these speeds. I ran a random sort command on an unindexed mailbox in order to get it to index. Results, for a mailbox with 10GB Inbox, spread in 65 000 files: 3 UID SORT (ARRIVAL) US-ASCII OR OR OR FROM "dfgfgfgf" SUBJECT "dfgfgfgf" TO "dfgfgfgf" CC "dfgfgfgf" a03 select INBOX * SORT 3 OK Sort completed (2455.549 + 0.122 + 1.477 secs). Index cache file at the end was 31MB in size: 30756376 Apr 18 02:14 dovecot.index.cache Is that normal, slow or fast ? Second question is, how can I speed this up ? I store messages using Director over NFS , on top of ZFS. From what I've read it would be fairly safe to disable mail_fsync but I don't think that would help much with the indexing speed. Any other tips ?

I have narrowed it down to this simple test case: # dovecot -n # 2.3.1 (c5a5c0c82): /etc/dovecot/dovecot.conf # OS: Linux 4.4.0-119-generic x86_64 Ubuntu 16.04.4 LTS # Hostname: tuxi.topfen.net first_valid_gid = 200 first_valid_uid = 200 mail_location = mbox:~/mail passdb { args = password=secret driver = static } plugin { sieve = file:~/sieve;active=~/.dovecot.sieve } protocols = lmtp service lmtp { inet_listener lmtp { address = 127.0.0.1 port = 24 } } userdb { args = uid=200 gid=200 home=/home/vmail driver = static } protocol lmtp { mail_plugins = sieve } # cat /home/vmail/.dovecot.sieve redirect "test(a)example.invalid"; stop; $ swaks --protocol lmtp -s 127.0.0.1 -f ulrich(a)topfen.net -t ulrich(a)topfen.net === Trying 127.0.0.1:24... === Connected to 127.0.0.1. <- 220 tuxi.topfen.net Dovecot ready. -> LHLO tuxi.topfen.net <- 250-tuxi.topfen.net <- 250-8BITMIME <- 250-CHUNKING <- 250-ENHANCEDSTATUSCODES <- 250-PIPELINING <- 250 VRFY -> MAIL FROM:<ulrich(a)topfen.net> <- 250 2.1.0 OK -> RCPT TO:<ulrich(a)topfen.net> <- 250 2.1.5 OK -> DATA <- 354 OK -> Date: Tue, 17 Apr 2018 18:44:42 +0200 -> To: ulrich(a)topfen.net -> From: ulrich(a)topfen.net -> Subject: test Tue, 17 Apr 2018 18:44:42 +0200 -> X-Mailer: swaks v20130209.0 jetmore.org/john/code/swaks/ -> -> This is a test mailing -> -> . <** 451 4.3.0 <ulrich(a)topfen.net> Temporary internal error -> QUIT <- 221 2.0.0 Bye === Connection closed with remote host. $ tail -n 10 /var/log/mail.log Apr 17 18:45:36 tuxi postfix/postdrop[22643]: warning: mail_queue_enter: create file maildrop/421882.22643: Permission denied Apr 17 18:45:36 tuxi dovecot: lmtp: Error: postdrop: warning: mail_queue_enter: create file maildrop/421882.22643: Permission denied Apr 17 18:45:36 tuxi dovecot: lmtp(ulrich(a)topfen.net)<22639><dtJZGJIk1lpvWAAAcdhj4Q>: Error: program `/usr/sbin/sendmail' was forcibly terminated with signal 15 Apr 17 18:45:36 tuxi dovecot: lmtp(ulrich(a)topfen.net)<22639><dtJZGJIk1lpvWAAAcdhj4Q>: Error: sieve: msgid=unspecified: failed to redirect message to <test(a)test.at>: Failed to execute sendmail (temporary failure) Apr 17 18:45:36 tuxi dovecot: lmtp(ulrich(a)topfen.net)<22639><dtJZGJIk1lpvWAAAcdhj4Q>: Error: sieve: Execution of script /home/vmail/.dovecot.sieve was aborted due to temporary failure (user logfile /home/vmail/.dovecot.sieve.log may reveal additional details) Apr 17 18:45:36 tuxi dovecot: lmtp(22639): Disconnect from 127.0.0.1: Client has quit the connection (state = READY) Apr 17 18:45:46 tuxi postfix/postdrop[22643]: warning: mail_queue_enter: create file maildrop/422091.22643: Permission denied Apr 17 18:45:46 tuxi dovecot: lmtp: Error: postdrop: warning: mail_queue_enter: create file maildrop/422091.22643: Permission denied Apr 17 18:45:56 tuxi postfix/postdrop[22643]: warning: mail_queue_enter: create file maildrop/422227.22643: Permission denied Apr 17 18:45:56 tuxi dovecot: lmtp: Error: postdrop: warning: mail_queue_enter: create file maildrop/422227.22643: Permission denied As far as I can tell, this is because Dovecot somehow does not allow suid programs to run (Postfix' postdrop(1), which is invoked by sendmail(1), requires set-gid to write the queue file). What can I do to change this (besides using SMTP from Dovecot directly)? I am using Ubuntu 16.04 and the Dovecot packages from the community repository: ~$ dpkg -l dovecot* | grep ^ii ii dovecot-core 2:2.3.1-1 amd64 secure POP3/IMAP server - core files ii dovecot-lmtpd 2:2.3.1-1 amd64 secure POP3/IMAP server - LMTP server ii dovecot-sieve 2:2.3.1-1 amd64 secure POP3/IMAP server - Sieve filters support Ulrich

dovecot-lda "-f" argment optional?
by Sebastian Arcus 17 Apr '18

17 Apr '18

I use dovecot-lda to deliver incoming email from Exim to Dovecot. After having some problems with email bounces with empty envelope sender not being delivered because of an empty -f argument, I discovered that Exim can pass email to Dovecot using dovecot-lda without using the -f argument at all. Would this have any adverse effects anywhere else? The docs don't even seem to specify if -f is optional or not - but I guess it is - as it seems to be working without it. Does anybody know what is its role? I'd like to understand things a bit before I just start removing it permanently from my setup.

[bug] Auth cache, proxy and ITERINDEX
by azurit＠pobox.sk 17 Apr '18

17 Apr '18

Hi, today we have exceprienced really major difficulties with our proxy backend servers. Everything started after enabling auth cache: auth_cache_size = 100M auth_cache_verify_password_with_worker = yes auth_cache_ttl = 1 hour auth_cache_negative_ttl = 1 hour Soon after we start receiving lots of calls from our customers about 'missing all e-mail messages'. This was in errors logs on master server: Apr 16 14:37:10 server00 dovecot: imap(<censored_email_address>): Error: autoexpunge: Couldn't create dovecot.autoexpunge.lock lock: file_create_locked(/var/mail/vhosts/<censored_domain>/<censored_name>/home/dovecot.autoexpunge.lock) failed: safe_mkstemp(/var/mail/vhosts/<censored_domain>/<censored_name>/home/dovecot.autoexpunge.lock) failed: No such file or directory Looks like that all users, who are placed on proxy backends, were logged correctly BUT not proxied to the right server so they saw empty mailboxes (Dovecot also created some directories on master server). What is worse, their email software deleted all local emails so they are now downloading everything from scratch (100Gs of mails so it will take some time). After auth cache was disabled, things started to go to normal EXCEPT users were reporting they don't see all folders - which was true, only few on them were visible (INBOX, trash, sent etc.). We tried everything to make them visible again, for example deleting indexes, but nothing helped. Finally, removing option ITERINDEX from mail_location helped. Can anyone explain what happened? Thank you azurIt

spamc scripts in IMAPSieve docs.
by Reio Remma 17 Apr '18

17 Apr '18

Hello! I noticed SpamAssassin *spamc* usage has entered the documentation at https://wiki2.dovecot.org/HowTo/AntispamWithSieve I'm wondering if the -C (report) option in sa-learn-ham.sh should use revoke instead of report for --ham messages? I started using imapsieve with spamc myself just a few weeks ago, but I haven't used the reporting ability yet. Reio

File system permissions - setgid bit and Netapp NFS volumes
by Shaun Johnson 17 Apr '18

17 Apr '18

Greetings Dovecot List, I have a bit of an edge case I am trying to resolve. I am currently using dovecot on Ubuntu 14.04 - Ubuntu package version: 1:2.2.9-1ubuntu2.3 I have attached the output of doveconf -n to this email - but to describe the configuration in a nutshell: my server is configured to use Maildir storage I do not use dovecot delivery service (there is a separate program in my system delivering messages) I am using a 'checkpassword' mechanism for authentication My mail storage is mounted via NFSv3 from a Netapp Filer FAS3050 configured to set anonuid=89, read write access, and root access. Dovecot has been configured with: mail_fsync = always mail_nfs_index = yes mail_nfs_storage = yes mmap_disable = yes lock_method = fcntl In order to function with the other components of my system, the Mail Storage directories are expected to have permissions: drwx--S--- uid 89: gid 89 The oddity I am encountering came up recently when I set up a job to monitor and correct directory permissions. I found after observing the system in action that overtime, the ~/Maildir directories for all active mailboxes would mysteriously lose the setgid bit. Now, while the system still functioned, it was something unexpected so I investigated further by turning on auditd to monitor what was changing the permissions on the path. After tracing through the results, I found an entry indicating that the 'imap' process of dovecot was performing a 'chown' call on the directory, with an end result of the previous mode 2700 being changed to 0700. Now I understand that on some filesystems, a 'chown' call can end up losing any setuid or setgid bits on an inode - and apparently Netapp's WAFL file system is one of them. Looking at the dovecot source code, I *believe* the source of the chown call is in src/lib/nfs-workarounds.c function nfs_flush_chown_uid - where a 'chown' call is being used to flush NFS attribute caches? for what I believe is the purposes of ascertaining file lock status? My question for you folks is if anyone else has encountered this on other file systems (or filers) - and if there is a native method in dovecot - either the version I am currently running or an updated newer version - that allows one to either retain the permissions assigned to a directory or specify the permissions I expect on the Maildir directory structures. Any feedback would be welcome, thanks! -- Shaun Johnson LinuxMagic Inc. 604-682-0300 Beautiful British Columbia, Canada

LDAP Homedir location: Needs dovecot restart after change it
by Andre Luiz Paiz 16 Apr '18

16 Apr '18

Dear group members. I work with Dovecot and Openldap authentication. Sometimes users change departments and we need to alter their homedir location. Every time this process is needed, I perform this steps: 1 - Change homedir location in openldap 2 - Move homedir folder to the new location 3 - Re-apply permissions 4 - Remove user index folder After I do that, users cannot authenticate unless I restart dovecot, process that I would like to avoid. Can you guys give a tip on what I need to change to avoid this last problematic step? After the restart, everything works. Does the auth_cache feature also store the homedir location?

Is FTS needed for Subject/Recipient/Sender server-side searches?
by Sebastian Arcus 16 Apr '18

16 Apr '18

I've had a number of Dovecot installs happily running for quite a few years now, but I've just stumbled over a new issue. I am trying to get some iPhones to do server-side email searches through ActiveSync/Exchange protocol -> Horde -> Dovecot. The bit I can't figure out is if I need to enable and configure FTS in Dovecot for that to work? I've tested server-side email searches against the same Dovecot server on Thunderbird - through IMAP (there is an option to force the search on the server in Thunderbird) - and it is working really well and fast. I am only really interested in Sender/Recipient/Subject searches. Server-side searching is not working at the moment on the iPhones side - although I can see the ActiveSync commands being sent to Horde. Anyway, to begin with, does anybody know if server-side IMAP searches need FTS in Dovecot (Horde is talking to Dovecot through IMAP). The fact that they work fine in Thunderbird would suggest the answer is 'no' - but could someone confirm that is correct please? Anticipated thanks for any hints. I am on Dovecot 2.2.33 if in case it matters.

52.184.164.73 in my logs
by daniel_1983＠protonmail.com 15 Apr '18

15 Apr '18

Dear list, One of my users is reading e-mail from his phone. When he logs in, this is what I see in my logs : Apr 10 16:17:58 auth-worker(17101): Debug: sql(xxx(a)mydomain.tld,52.184.164.73): query: SELECT email as user, password FROM users WHERE email = LOWER('xxx(a)mydomain.tld') [...] Apr 10 16:17:58 imap-login: Info: Login: user=<xxx(a)mydomain.tld>, method=LOGIN, rip=52.184.164.73, lip=10.10.10.19, mpid=19286, TLS, session=<E6cEB4BprgA0uKRJ> Both lines show a remote IP of 52.184.164.73, which is strange since all my users are, and connect from, Algeria. According to the ispinfo website (http://www.ispinfo.net/isp/52.184.164.73.html) this IP belongs to Microsoft. Could it be that the outlook app uses microsoft's servers to fetch the mail before handing them to the user ? Daniel.

ACL for system users?
by Rubén Fernández Asensio 13 Apr '18

13 Apr '18

Hello all, I'm setting up an IMAP server with dovecot. I've set up system users with PAM authentication and Maildir maiboxes. I'd like to share mailboxes among them, but regardless of what I try, I bump into filesystem permissions. I want to have Maildirs created for new users with the right permissions. I even changed "UMASK" in file /etc/login.defs from 022 to 002, but the Maildirs are still created with 700 permissions: ls -l /home/ximplet2/ total 4 drwx------ 9 ximplet2 users 4096 Apr 12 19:10 Maildir Really there's no better way than running "chmod -R g=u /home/ximplet2/Maildir" and "chmod g+s /home/ximplet2/Maildir" for every user? Really?? I read that, before v.2, Dovecot had a "umask" option to do precisely want I need, but it was removed. How are we supposed to use ACL with system users nowadays?

Hi, This code path is only executed when there is a return-path header. Given the fact that this fails consistently, can you provide an example of a message successfully delivered using an older version of Dovecot; i.e., as it is stored in the mailbox? There should be a return-path header there. Alternatively, you could temporarily wrap dovecot-lda in a shell script that copies the message to some file you can read after. I just need one example to confirm my suspicions. Regards, Stephan.

dovecot, imap sieve, roundcube markasjunk2 plugin
by David Mehler 10 Apr '18

10 Apr '18

Hello, Does anyone have the above combination going? Per the wiki: https://wiki.dovecot.org/HowTo/AntispamWithSieve I have configured Dovecot for imap sieve and rspamd setting up the learn sieve and shell scripts. This is working. Now i'd like to integrate roundcube's markasjunk2 plugin. Looking at it's config file I am uncertain as to which options to enable. If anyone has a working markasjunk2 roundcube config that works with dovecot and imap sieve i'd appreciate seeing it. Thanks. Dave.

IMAP_ID_LOG
by j.emerlik 10 Apr '18

10 Apr '18

Hi, there in configuration is possibile to set imap_id_log for logging Client ID e.g.: ID sent: name=Thunderbird, version=52.7.0. Is possible to set same but for POP3 or SMTP Auth ? Ideally, it would be possible to log in to the database e.g. using postlogin script. Regards, MattX

Filesystem level backups?
by Steve Atkins 09 Apr '18

09 Apr '18

Up until now I've been backing up my IMAP server by taking an atomic snapshot of the entire VM, so I've not really had to worry about it. I'm moving to hosting where I have neither VM snapshots nor a filesystem that can take snapshots, so I need to think about consistent backups a bit more. Will a simple backup of all the files of an multi-dbox give me a consistent state when I recover, or do I need to do something (e.g. lock writes to the mailbox) while I run a backup? (I could use doveadm backup if I were backing up to local storage I controlled, but I'm pushing it to offsite buckets so I'd prefer to avoid backing up the entire thing locally, then copying that offsite). Cheers, Steve

For backup I use the command 'dsync -o plugin/quota= -f -u user@domain backup dbox:/backup/dir' When I execute this command with the -D option, I get to see (above only Debug messages) dsync(user@domain): Panic: file mailbox-attribute.c: line 362 (mailbox_attribute_get_stream): assertion failed: (value_r->value != NULL || value_r->value_stream != NULL) dsync(user@domain): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0xcc724) [0x7f0f15364724] -> /usr/lib64/dovecot/libdovecot.so.0(default_fatal_handler+0x2a) [0x7f0f1536476a] -> /usr/lib64/dovecot/libdovecot.so.0(i_fatal+0) [0x7f0f152d524b] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x566ac) [0x7f0f156686ac] -> doveadm(dsync_mailbox_import_attribute+0x4d) [0x5581a663bf4d] -> doveadm(dsync_brain_sync_mails+0x2ef) [0x5581a66377ff] -> doveadm(dsync_brain_run+0x2b0) [0x5581a6632e90] -> doveadm(+0x2960c) [0x5581a661a60c] -> doveadm(+0x2b4f7) [0x5581a661c4f7] -> doveadm(+0x2c0dc) [0x5581a661d0dc] -> doveadm(doveadm_mail_try_run+0x205) [0x5581a661da75] -> doveadm(main+0x475) [0x5581a660cce5] -> /lib64/libc.so.6(__libc_start_main+0xf5) [0x7f0f14ca3c05] -> doveadm(+0x1be65) [0x5581a660ce65] cancelled my dovecot -n output: #

Clients connect to the main server only, which is where mail comes in. The second one that experiences the problem with locking is only a redundant server which is a secondary MX, that only gets occasional SMTP deliveries from time to time. So the amount of replication back from the "secondary" is very minimal; the vast bulk of the replication is the primary replicating changes out. Reuben

changed behavior for dovecot-lda in 2.3.x
by Martin Waschbüsch 08 Apr '18

08 Apr '18

Hi all, Hey all, I upgraded to dovecot 2.3.1 (from 2.2.34) and noticed that the behavior for dovecot-lda changed. Apparently it no longer accepts -f "" or -f "<>? With 2.2.34, both were accepted now I get: root@mail:~# /usr/local/libexec/dovecot/dovecot-lda -f "<>" lda(root): Fatal: Invalid -f parameter: Null path not allowed or root@mail:~# /usr/local/libexec/dovecot/dovecot-lda -f "" lda(root): Fatal: Invalid -f parameter: Path is empty string I guess this must be a bug? I mean, envelope sender *must* be empty for bounces. Thanks, Martin

Hello, I'm wanting to make a shared folder that anyone in a domain can get to, but not anyone in any other domain. Here's my dovecot shared namespace: namespace { type = shared separator = / prefix = shared/%%u/ location = maildir:%%h:INDEX=~/shared/%%u subscriptions = no list = yes } The dovecot-dict-sql.conf.ext file has: map { pattern = shared/shared-boxes/user/$to/$from table = user_shares value_field = dummy fields { from_user = $from to_user = $to } } map { pattern = shared/shared-boxes/anyone/$from table = anyone_shares value_field = dummy fields { from_user = $from } } and in my global acl file I have: shared/office@ user(a)domain.com lrwstipekxa shared/office@ user2(a)domain.com lrwstipekxa Thanks.

Dsync from multiple IMAPs -- personal/local dovecot setup
by Kim ALLAMANDOLA 06 Apr '18

06 Apr '18

Hello list, new aspiring user here, if I'm not in the wright place sorry, I do not fund any other option for now... As from subject I'm looking for a *personal* *standalone* dovecot setup, especially I'm looking for a DSync from multiple IMAP accounts to a local maildir (to being compatible with notmuch). My actual mail setup is: OfflineIMAP that sync different mailboxes in a personal taxonomy ~/mail/$mailboxName/... and notmuch-emacs + various scripts as MUA. Local postfix just to avoid emacs freeze during send, muchsync to support It does work but is slow, buggy and sometime complicated to kept up to date (I have many homegrow spaghetti-code scripts and snippets in zsh, elisp, python etc stratified in years). My dream is switch to a local Dovecot that DSync from multiple IMAPs instead of OfflineIMAP, with sieve filters instead of homegrow scripts that wrap notmuch search --output=files | xargs ... For the MUA part I'd like to stick with notmuch. So my questions are: is possible to dsync from multiple IMAPS to a maildir? if yes does dovecot accept physical messages moves if I refile (archive etc) them via notmuch? Thanks! -- Kim ALLAMANDOLA

Replication has been working for years now, without any glitches at all. > > Regards, > Michael It's not just you. This issue hit me recently, and it was impacting replication noticeably. I am following git master-2.3 . Here's a last known reasonably good point in the tree where things worked quite well: EGIT_REPO_URI="https://github.com/dovecot/core.git" EGIT_BRANCH="master-2.3" EGIT_COMMIT="d9a1a7cbec19f4c6a47add47688351f8c3a0e372" So something after that (which could have gone into 2.3.1) has caused this. There is also a second issue of a long standing race with replication occurring somewhere whereby if a mail comes in, is written to disk, is replicated and then deleted in short succession, it will reappear again to the MUA. I suspect the mail is being replicated back from the remote. A few people have reported it over the years but it's not reliable or consistent, so it has never been fixed. And lastly there has been an ongoing but seemingly minor issue relating to locking timing out after 30s particularly on the remote host that is being replicated to. I rarely see the problem on my local disk where almost all of the mail comes in, it's almost always occurring on the replicate/remote system. For me it seems very unlikely that on an unloaded/idle VPS there are legitimate problems obtaining a lock in under 30s. This is with the default locking configuration. This problem started happening a lot more after the breakage in (1) above. These replication issues are similar, and could possibly be related. My system is Gentoo Linux keeping up with the latest kernels, and on an EXT4 FS. I am using TCPS based replication. My remote replicate is also on Gentoo Linux with EXT4 but on a Linode VPS (around 250ms latency away). I know in a later post you've said that you don't think it has anything to do with dovecot-2.3.1, so I'd be interested to know what really is the cause in that case. Reuben

dovecot welcome scripts for multiple domains
by David Mehler 06 Apr '18

06 Apr '18

Hello, I've got dovecot 2.3 going, and it uses welcome scripts successfully. My question is does anyone have a script that is multi-domain capable? Currently mine sends it's welcome message from say postmaster(a)domain1.com, well I've got five domains, can I set this script up so that it's smart about them? If user(a)domain3.com logs in it would send a message from postmaster(a)domain3.com? If anyone has any welcome scripts i'm curious to take a look. Thanks. Dave.

issue with sieve forwarding after upgrade to 0.5.1
by Christos Chatzaras 05 Apr '18

05 Apr '18

Finally I found a workaround to not depend on sendmail to forward messages using sieve: In postfix main.cf I have: authorized_submit_users = root, filter (I want only root and filter to use sendmail and block other users to send e-mails from system accounts. Only allow users to send e-mails from virtual accounts and after smtp authentication. Username filter is used for bogofilter and needs access to sendmail) And in dovecot.conf: submission_host = 138.201.248.xxx The same workaround maybe works for NoNewPrivileges too as the authorized_submit_users setting in postfix has similar result.

I have to be clear on that to move forward. I have tried finding solutions about it but couldn't find anything which talks about it. We have a setup which includes postfix and dovecot. We are using lmtp and delivery of mail is happening through dovecot. We want that delivery of mail should happen in a separate node. I was able to achieve it through lmtp by providing ip address and using port 24. But now I have been asked to just try to deliver to a separate storage medium and not node. That means it will have an ip address but no dovecot or other software running. This is in relation to incorporation of storage area network (SAN) later on. Is it possible? I thought there must be some way as many running mail systems are using message store and SAN. All i can find that was close was mailbox sharing and email archiving. Please help me about this as I have already spent 3 days to it with no luck. I just want the right direction to move forward on this. Regards

Doveadm backup issues on dovecot 2.3.1

issue with sieve forwarding after upgrade to 0.5.1
by Christos Chatzaras 04 Apr '18

04 Apr '18

Hello, After I upgrade dovecot 2.2.35 to 2.3.1 and pigeonhole 0.4.23 to 0.5.1 when I use sieve to forward a message to other address using "redirect :copy" I get this: (host server1.myserver.com <http://server1.myserver.com/>[private/dovecot-lmtp] said: 451 4.2.0 <chris(a)mydomain.com <mailto:chris@mydomain.com>> Execution of Sieve filters was aborted due to temporary failure (in reply to end of DATA command)) And in sieve log I see: failed to redirect message to <chris(a)mydomain.com <mailto:chris@mydomain.com>>: Sendmail program returned error (temporary failure). Any idea what is wrong? Kind regards, Christos Chatzaras

Saving Drafts with Roundcube marks old Mails in INBOX as unread.
by sk＠tyrion.de 04 Apr '18

04 Apr '18

Hello List, I have a problem with the client Roundcube. Whenever I save a draft to the Folder INBOX.Drafts a old mail in my INBOX will be marked as unread. Here are the IMAP Logs from Roundcube and Dovecot debug logs. I have no idea why it happens. The IMAP protocol looks normal to me but as you can see in the second to last line in the Dovecot log Dovecot is changing the flag of an old E-Mail in INBOX that has the same UID as the Mail that was just created in INBOX.Drafts.

Use of separate storage for mail delivery
by SAAHIL IFTEKHAR 04 Apr '18

04 Apr '18

Hi I am facing one issue which is mostly about concepts. I have to be clear on that to move forward. I have tried finding solutions about it but couldn't find anything which talks about it. We have a setup which includes postfix and dovecot. We are using lmtp and delivery of mail is happening through dovecot. We want that delivery of mail should happen in a separate node. I was able to achieve it through lmtp by providing ip address and using port 24. But now I have been asked to just try to deliver to a separate storage medium and not node. That means it will have an ip address but no dovecot or other software running. This is in relation to incorporation of storage area network (SAN) later on. Is it possible? I thought there must be some way as many running mail systems are using message store and SAN. All i can find that was close was mailbox sharing and email archiving. Please help me about this as I have already spent 3 days to it with no luck. I just want the right direction to move forward on this. Regards

2.3.1 Replication is throwing scary errors
by Michael Grimm 03 Apr '18

03 Apr '18

Hi [This is Dovecot 2.3.1 at FreeBSD STABLE-11.1 running in two jails at distinct servers.] I did upgrade from 2.2.35 to 2.3.1 today, and I do become pounded by error messages at server1 (and vice versa at server2) as follows: | Apr 2 17:12:18 <mail.err> server1.lan dovecot: doveadm: Error: dsync(server2.lan): I/O has stalled, \ no activity for 600 seconds (last sent=mail_change, last recv=mail_change (EOL)) | Apr 2 17:12:18 <mail.err> server1.lan dovecot: doveadm: Error: Timeout during state=sync_mails \ (send=changes recv=mail_requests) […] | Apr 2 18:59:03 <mail.err> server1.lan dovecot: doveadm: Error: dsync(server2.lan): I/O has stalled, \ no activity for 600 seconds (last sent=mail, last recv=mail (EOL)) | Apr 2 18:59:03 <mail.err> server1.lan dovecot: doveadm: Error: Timeout during state=sync_mails \ (send=mails recv=recv_last_common) I cannot see in my personal account any missing replications, *but* I haven't tested this thoroughly enough. I do have customers being serviced at these productive servers, *thus* I'm back to 2.2.35 until I do understand or have learned what is going on. Any ideas/feedback? FYI: I haven't seen such errors before. Replication has been working for years now, without any glitches at all. Regards, Michael

dovecot auth error: Illegal seek
by panetta 03 Apr '18

03 Apr '18

Hi, I recently configured dovecot to manage auth for both local and virtual user. When i login as a virtual user (claudio.panetta) I get the following message: dovecot: auth: Error: passwd(claudio.panetta,160.97.62.1,<WLjlnZ9oRACgYT4B>): getpwnam() failed: Illegal seek but login is ok and sending/receiving email is ok, how can, if possible, I suppress this error message? In the following my dovecot config: host-prompt# dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-5-686-pae i686 Debian 7.11 auth_mechanisms = plain login auth_username_format = %Ln listen = * log_timestamp = "%Y-%m-%d %H:%M:%S " login_greeting = Server ready. mail_full_filesystem_access = yes mail_location = mbox:~/:INBOX=/var/mail/%u:INDEX=/var/index/%u mail_privileged_group = mail passdb { driver = pam } passdb { args = scheme=MD5-CRYPT username_format=%n /etc/dovecot/users driver = passwd-file } protocols = " imap" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = root } service imap-login { inet_listener imap { port = 0 } } ssl_cert = </etc/ssl/certs/chained-cert-9599-ml.mat.unical.it.pem ssl_key = </etc/ssl/private/csrkey-ml.mat.unical.it.pem userdb { driver = passwd } userdb { args = username_format=%n /etc/dovecot/users uid=vmail gid=vmail home=/var/vmail/%d/%n mail=maildir:/var/vmail/%d/%n/Maildir driver = static } verbose_proctitle = yes host-prompt# cat /etc/dovecot/users claudio.panetta:{MD5-CRYPT}$1$abcdefghijklmnopqrst ciccio.pasticcio:{MD5-CRYPT}$1$abcdefghijklmnopqrst Regards, Claudio

multi-site SSL certificates
by Jeff Abrahamson 03 Apr '18

03 Apr '18

I'm handling mail for several domains, let's call them a.com, b.com, and c.com. I have certificates for each of these domains individually via certbot (letsencrypt) and nginx is happy with all of that. Since I initially configured the site to handle mail only for a.com, my /etc/postfix/main.cf file currently has these two lines: smtpd_tls_cert_file = /etc/letsencrypt/live/mail.a.com/fullchain.pem smtpd_tls_key_file = /etc/letsencrypt/live/mail.a.com/privkey.pem But I see that mail test tools are reporting that MX for b.com and c.com are misconfigured due to an SSL name mismatch. Indeed, this is true! So I believe I should generate a multi-site SSL cert. I try this: sudo certbot certonly --cert-name postfix --webroot \ --webroot-path /var/www/a-com -d www.a.com -d a.com -d mail.a.com \ --webroot-path /var/www/b-com -d www.b.com -d b.com \ --webroot-path /var/www/c-com -d www.c.com -d c.com And that fails with a bunch of errors like this: Domain: www.a.com Type: unauthorized Detail: Invalid response from http://www.a.com/.well-known/acme-challenge/IT7-YURAep4bniD9zYpKpdRUBQcgCRJ…: "<html> <head><title>404 Not Found</title></head> <body bgcolor="white"> <center><h1>404 Not Found</h1></center> <hr><center>" I see that the file .well-known/acme-challenge/IT7-YURAep4bniD9zYpKpdRUBQcgCRJ6FflmZzWQGNg is being created (and one other file, too) but that nginx reports that the _directory_ .well-known/acme-challenge/IT7-YURAep4bniD9zYpKpdRUBQcgCRJ6FflmZzWQGNg doesn't exist. Multi-site + letsencrypt + postfix is a subject that has recently changed quite a bit, so I'm suspecting my web reading is merely leading me astray. It is also entirely possible I've misunderstood things about SSL certificates. Any pointers how to generate (or point to) the certificates that I need to make those who contact my postfix instance happy with their SSL conversation? Thanks!

dovecot lastlogin tracking

Hello, I am trying to get Dovecot 2.3.1 to track lastlogins of users. I'm using a MySQL database.

Issue with a bug with imap-login
by Grant Keller 31 Mar '18

31 Mar '18

Hello, Currently working on migrating our existing directors from 2.1.13 to 2.2.10. In 2.2.10 when issuing the logout command on an unauthenticated connection, the connection is closed before the server sends the BYE line to the client. The new version works as expected with a non-secure connection. I will include the strace output from the imap-login process that shows the connection closing before the message can be sent. # 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux

debian lintian warn: hardening-no-fortify-functions
by A. Schulze 30 Mar '18

30 Mar '18

Hello, to build + packages dovecot I use the usual Debian tool chain. That includes build with selected GCC options and running lintian. I notice since a long time (read: many earlier versions, up to 2.2.35) this lintian warnings: I: dovecot-core: hardening-no-fortify-functions usr/lib/dovecot/auth N: N: This package provides an ELF binary that lacks the use of fortified libc N: functions. Either there are no potentially unfortified functions called N: by any routines, all unfortified calls have already been fully validated N: at compile-time, or the package was not built with the default Debian N: compiler flags defined by dpkg-buildflags. If built using N: dpkg-buildflags directly, be sure to import CPPFLAGS. N: N: NB: Due to false-positives, Lintian ignores some unprotected functions N: (e.g. memcpy).

Frequentl failures to create /tmp/dovecot.imap
by Peter 29 Mar '18

29 Mar '18

I am using dovecot 2.2.27 with plesk 12 and I have made no modifications to the dovecot config. my log file frequently (but not always!) reports errors that /tmp/dovecot.imap could not be created. The errors don't appear for every imap connect but for about 5% to 10% of the time. I already attempted to solve the problem by adding the following line to /etc/dovecot/dovecot.conf but that did not remove the error: mail_temp_dir = /tmp So why does dovecot mostly work without errors but sometimes fails to create the /tmp/dovecot.imap? ..excerpt from /var/log/syslog... dovecot: service=imap, user=user1(a)mydomain1.com, ip=[::1].

Release 2.3.1
by aki.tuomi＠dovecot.fi 29 Mar '18

29 Mar '18

Hi! We are releasing v2.3.1, which mostly consists of bug fixes for 2.3.0, and few improvements. This is also available via https://repo.dovecot.org if you want packages. libsodium support didn't get into this build, due to build environment issues, but 2.3.2 will contain it. * Submission server support improvements and bug fixes - Lots of bug fixes to submission server * API CHANGE: array_idx_modifiable will no longer allocate space - Particularly affects how you should check MODULE_CONTEXT result, or use REQUIRE_MODULE_CONTEXT. + mail_attachment_detection_options setting controls when $HasAttachment and $HasNoAttachment keywords are set for mails. + imap: Support fetching body snippets using FETCH (SNIPPET) or (SNIPPET (LAZY=FUZZY)) + fs-compress: Automatically detect whether input is compressed or not. Prefix the compression algorithm with "maybe-" to enable the detection, for example: "compress:maybe-gz:6:..." + Added settings to change dovecot.index* files' optimization behavior. See https://wiki2.dovecot.org/IndexFiles#Settings + Auth cache can now utilize auth workers to do password hash verification by setting auth_cache_verify_password_with_worker=yes. + Added charset_alias plugin. See https://wiki2.dovecot.org/Plugins/CharsetAlias + imap_logout_format and pop3_logout_format settings now support all of the generic variables (e.g. %{rip}, %{session}, etc.) -- Aki Tuomi Dovecot oy

murmurhash3 test failures on big-endian systems

Hi, The dovecot 2.3.0.1 Debian package currently fails to build on all big-endian architectures[1], due to murmurhash3 tests failing. The relevant output from e.g. s390x is: test-murmurhash3.c:22: Assert(#8) failed: memcmp(result, vectors[i].result, sizeof(result)) == 0 test-murmurhash3.c:22: Assert(#11) failed: memcmp(result, vectors[i].result, sizeof(result)) == 0 test-murmurhash3.c:22: Assert(#12) failed: memcmp(result, vectors[i].result, sizeof(result)) == 0 murmurhash3 (murmurhash3_32) ......................................... : FAILED test-murmurhash3.c:22: Assert(#1) failed: memcmp(result, vectors[i].result, sizeof(result)) == 0 test-murmurhash3.c:22: Assert(#2) failed: memcmp(result, vectors[i].result, sizeof(result)) == 0 test-murmurhash3.c:22: Assert(#3) failed: memcmp(result, vectors[i].result, sizeof(result)) == 0 test-murmurhash3.c:22: Assert(#4) failed: memcmp(result, vectors[i].result, sizeof(result)) == 0 test-murmurhash3.c:22: Assert(#5) failed: memcmp(result, vectors[i].result, sizeof(result)) == 0 test-murmurhash3.c:22: Assert(#6) failed: memcmp(result, vectors[i].result, sizeof(result)) == 0 test-murmurhash3.c:22: Assert(#7) failed: memcmp(result, vectors[i].result, sizeof(result)) == 0 test-murmurhash3.c:22: Assert(#8) failed: memcmp(result, vectors[i].result, sizeof(result)) == 0 test-murmurhash3.c:22: Assert(#9) failed: memcmp(result, vectors[i].result, sizeof(result)) == 0 test-murmurhash3.c:22: Assert(#10) failed: memcmp(result, vectors[i].result, sizeof(result)) == 0 test-murmurhash3.c:22: Assert(#11) failed: memcmp(result, vectors[i].result, sizeof(result)) == 0 test-murmurhash3.c:22: Assert(#12) failed: memcmp(result, vectors[i].result, sizeof(result)) == 0 test-murmurhash3.c:22: Assert(#13) failed: memcmp(result, vectors[i].result, sizeof(result)) == 0 murmurhash3 (murmurhash3_128) ........................................ : FAILED Looks like the murmurhash3 implementation in Dovecot is currently broken on big-endian systems.

[sieve][pigeonhole] Can't catch stdout for pipe script after upgrade Dovecot 2.2 -> 2.3
by Konstantin Shalygin 29 Mar '18

29 Mar '18

Hi. I use custom script: > require [ "vnd.dovecot.pipe", "variables" ]; > > if address :is :all "from" "snip@snap" > { > pipe "sieve_to_owncloud"; > } sieve_to_owncloud: > DATE=`date +%Y-%m-%d_%H-%M-%S` > PYTHONIOENCODING=utf8 python /opt/sieve-pipe/python-imap-to-owncloud.py \ > --owncloud-host https://<snip-snap> \ > --owncloud-user user \ > --owncloud-password secret \ > --owncloud-path /path/to/here &>/tmp/sieve_logger_py_${DATE} On dovecot 2.2 after script execution I will get plaintext log files on /tmp. After upgrade - don't. I also changed transport to lmtp when upgrade. Any ideas where is my stdout? k

Master Users, ACL and POP3
by Riccardo Bicelli 28 Mar '18

28 Mar '18

Hello, I'm on Dovecot 2.0.9 and I'mfacing issues connecting via POP3 with master user. I'm using the ACL plugin, so I set up a postlogin script that sets the current user as master user: #!/bin/sh MASTER_USER=$USER exec "$@" When I login via IMAP everything seems ok, but when I try via POP3 I get: -ERR [IN-USE] Couldn't open INBOX: Mailbox doesn't exist: INBOX Connection closed by foreign host. Any hints? Thanks

Dovecot quota
by David Mehler 28 Mar '18

28 Mar '18

Hello, I'm running Dovecot on a FreeBSD system with Postfix in a virtual user setup, with Mysql. I am trying to understand the quota configuration. I've got a Mysql database with an accounts table with a quota field. I've also got two other tables one quota (currently has nothing in it an empty set), and quota2 messages and bytes which has one entry. My goal is to have different quotas for each user so say one user has a 512MB quota I put 512 in the accounts quota column, while another user might have 256MB, put 256 in the accounts quota column. These are just examples. I'm assuming messages in the quota2 table track how many messages are under that user's is it inbox or all folders in the account? And bytes is that the space being taken up again by inbox or by all messages in the account? I'm also trying to have a separate quota for my public folders, which is not working. If anyone could take a look at this configuration see if it looks good and maybe where public is not happening i'd appreciate it. Thanks. Dave.

Released Pigeonhole v0.5.1 for Dovecot v2.3.1.
by Stephan Bosch 28 Mar '18

28 Mar '18

Hello Dovecot users, Here's the Pigeonhole release that goes with Dovecot v2.3.1. You will need this release for Dovecot v2.3.1, because the previous v0.5.0.1 release will not work. Apart from compatibility changes, it only contains bugfixes. Changelog v0.5.1: - Explicitly disallow UTF-8 in localpart in addresses parsed from Sieve script. - editheader extension: Corrected the stream position calculations performed while making the modified message available as a stream. Pigeonhole Sieve crashed in LMTP with an assertion panic when the Sieve editheader extension was used before the message was redirected. Experiments indicate that the problem occurred only with LMTP and that LDA is not affected. - fileinto extension: Fix assert panic occurring when fileinto is used without being listed in the require line, while the copy extension is listed there. This is a very old bug. - imapsieve plugin: Do not assert crash or log an error for messages that disappear concurrently while applying Sieve scripts.

dovecot logging
by A. Schulze 27 Mar '18

27 Mar '18

Hello, I'm currently playing with a number of dovecot instances to evaluate my "next generation setup" For now I run 6 instances of dovecot, one per docker container: - 2x redirector - 2x backend #1 - 2x backend #2 All docker container use syslog. And there the problems starts. Every instance identify itself as "dovecot" That's not helpful :-/ I tried to set an instance name but that change nothing. My options are now - let rsyslogd separate the sources by IP - use logfiles files Are there other? Currently the code use a fixed string "dovecot": https://github.com/dovecot/core/blob/master/src/lib-master/master-service.c… I would ask if it's possible to use the instance name as syslog identifier, too?

Slow imap connection to local dovecot server
by Lothar Paltins 27 Mar '18

27 Mar '18

Hi, this is my setup: OpenSuse tumbleweed dovecot 2.3.0.1 (ffd8a29) thunderbird 52.6.0 I'm running a local dovecot server on my private network to be able to access my saved mails from several computers on the network. The network is behind a firewall, therefore I'm only using plain imap on port 143 with plain text password authentification. But very often the login from thunderbird to the dovecot server takes a very long time, even if thunderbird and dovecot are running on the same machine. It can take more than a minute until I can read a message. I dont't have this problem with the remote imap servers of my mail providers. Does anybody know, why this happens or how I could debug this issue?

Duplicate mails on pop3 expunge with dsync replication on 2.2.35 (2.2.33.2 works)
by Gerald Galster 27 Mar '18

27 Mar '18

Hello, consider the following setup with dovecot 2.2.35: smtp/587 (subject: test 1535) | | mx2a.example.com --> dsync/ssh --> mx2b.example.com | pop3 fetch/expunge (uid 23) | !! dsync (copy from INBOX -> uid 24) /| dsync (expunge uid 23) / The pop3 client deletes mail from the server which triggers a copy from INBOX before it is expunged. On the next pop3 fetch you get the copy of the mail you thought had been expunged. This occurs only if mail is received by smtp on mx2a, synced to mx2b via dsync/ssh and then expunged via pop3 on mx2b. It does not occur if mail is received and expunged on mx2b. As a temporary workaround the system has been downgraded to 2.2.33.2. There are no duplicate emails after expunge with this version. 2.2.34 has not been tested. Does anyone know if there were changes in the dsync code from 2.2.33.2 to 2.2.35? Log: (mail received on mx2a.example.com and delivered via dsync to mx2b.example.com, then expunged via pop3 on mx2b.example.com -> copy/duplicate) Mar 26 15:35:57 mx2b.example.com dovecot[3825]: pop3-login: Login: user=<poptest(a)example.com>, method=PLAIN, rip=91.0.0.1, lip=188.0.0.1, mpid=3922, TLS, TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits) Mar 26 15:35:58 mx2b.example.com dovecot[3825]: pop3(poptest(a)example.com): expunge: box=INBOX, uid=23, msgid=<ACD482CD-443E-479A-A9E9-67549E186E35(a)example.com>, size=1210, subject=test 1535 Mar 26 15:35:58 mx2b.example.com dovecot[3825]: pop3(poptest(a)example.com): Disconnected: Logged out top=0/0, retr=1/1259, del=1/1, size=1242 Mar 26 15:35:58 mx2b.example.com dovecot[3825]: doveadm: Error: dsync-remote(poptest(a)example.com): Info: copy from INBOX: box=INBOX, uid=24, msgid=<ACD482CD-443E-479A-A9E9-67549E186E35(a)example.com>, size=1210, subject=test 1535 Mar 26 15:35:58 mx2b.example.com dovecot[3825]: doveadm: Error: dsync-remote(poptest(a)example.com): Info: expunge: box=INBOX, uid=23, msgid=<ACD482CD-443E-479A-A9E9-67549E186E35(a)example.com>, size=1210, subject=test 1535 (mail received on mx2b.example.com and expunged via pop3 on mx2b.example.com -> no copy/duplicate) Mar 26 15:36:09 mx2b.example.com dovecot[3825]: pop3-login: Login: user=<poptest(a)example.com>, method=PLAIN, rip=91.0.0.1, lip=188.0.0.1, mpid=3927, TLS, TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits) Mar 26 15:36:09 mx2b.example.com dovecot[3825]: pop3(poptest(a)example.com): expunge: box=INBOX, uid=24, msgid=<ACD482CD-443E-479A-A9E9-67549E186E35(a)example.com>, size=1210, subject=test 1535 Mar 26 15:36:09 mx2b.example.com dovecot[3825]: pop3(poptest(a)example.com): Disconnected: Logged out top=0/0, retr=1/1259, del=1/1, size=1242 Mar 26 15:36:10 mx2b.example.com dovecot[3825]: doveadm: Error: dsync-remote(poptest(a)example.com): Info: expunge: box=INBOX, uid=24, msgid=<ACD482CD-443E-479A-A9E9-67549E186E35(a)example.com>, size=1210, subject=test 1535 Thanks for looking into this Gerald

Quota set-up problems
by Marcin Norek 26 Mar '18

26 Mar '18

Hi, I've recently started using Dovecot as our main mail storage, and it's performing great. But I have a question/problems with quotas. First of we are using: dovecot --version 2.2.32 (dfbe293d4) Dovecot is a part of a pre set environment (mailcow-dockerized) Aside the inbox namespace we have set-up an additional archive ns (Archiwum) like this namespace Archiwum { type = private separator = / prefix = Archiwum/ location = maildir:/var/vmail/arch/%n:INDEXPVT=~/Maildir/Archiwum subscriptions = yes list = yes mailbox "Wyslane" { auto = subscribe } } It is on an separate disk array, and works well. The problem is that this namespace and all its sub mailboxes should have different quota then the main storage so the config is like this quota = dict:Userquota::proxy::sqlquota quota2 = maildir:ns=Archiwum quota_rule = Trash:storage=+100% quota2_rule = *:ignore It works.. but not as intender. While mail located directly in the name space are ignored everything in sub mailbox of the Archiwum is still accounted to the main quota. I've been fighting this for some time now and can not find the solution. So help would be appreciated. Regards Marcin

destuser setting useless on LMTP proxy
by Jan-Pieter Cornet 26 Mar '18

26 Mar '18

I tried setting the "destuser" setting on the LMTP director as follows, to preserve the original envelope rcpt: protocol lmtp { auth_socket_path = director-userdb passdb { driver = ... override_fields = destuser=%{orig_user} } } The passdb driver would return the appropriate "user" for each alias. Suppose, for example, user1 has emails user1(a)domain.tld, but also alias1(a)domain.tld. Now, it turns out that setting the destuser *changes* the backend. It seems that when the passdb returns "destuser", that username is completely ignored and the hashing of the destuser determines the backend chosen. This is incorrect, the backend should be chosen based on the returned "user", and the "destuser" should only be used for the remote login (or rcpt, in case of LMTP). I'm using version 2.2.35. The problem seems to be in lmtp/commands.c, in client_proxy_rcpt_parse_fields, line 281-285 says: } else if (strcmp(key, "user") == 0 || strcmp(key, "destuser") == 0) { /* changing the username */ *address = value; } ... So it looks as if "user" and "destuser" are treated equally in the LMTP proxy. -- Jan-Pieter Cornet <johnpc(a)xs4all.net> Systeembeheer XS4ALL Internet bv www.xs4all.nl

Config problem: Service #0 is missing name
by Chris Ross 25 Mar '18

25 Mar '18

Okay. So following up on the problems I was discussing weeks ago, I have hand-patched dovecot to work around problems that I believe may be in libc and not dovecot. Trying to get the properly built and installed dovecot-2.2.35, however, is giving me an error I haven’t seen before. I presume that something got munged while I was hand-configuring and installing/uninstalling/reinstalling the port in recent weeks. Running on a FreeBSD 11-stable machine, when I run “service dovecot start”, it tells me: % sudo service dovecot start Starting dovecot. Fatal: Error reading configuration: Invalid settings: Service #0 is missing name /usr/local/etc/rc.d/dovecot: WARNING: failed to start dovecot % Surprisingly, googling for “Service #0 is missing name” didn’t yield a suggestion. My config is the same as it had been previously, I believe. Does anyone have an idea what might be wrong here? Thanks. - Chris

recipient delimiter and sieve filters
by André Rodier 24 Mar '18

24 Mar '18

Dear all, I have found a way to automatically copy sent emails in the "Sent" folder, but I am not sure it is the simplest and more reliable way on the long term. I am open to suggestions if I miss a feature in Dovecot - or Postfix, that allows me to do this. I vaguely remember an SMTP extension that do that, but my memory could be wrong. First, I use "~" as a recipient delimiter. Then, I set up a postfix senders_bcc_map that add the ~Sent part: andre(a)homebox.space → bcc: andre~Sent(a)homebox.space It worked, except that the emails was marked as new. I tried first to add a global sieve filter like this: ---------------------------------------------------------------------- # Sieve script executed before for user require ["fileinto","imap4flags"]; # Move automatically copied emails to the sent folder # And mark them as read if header :contains "Delivered-To" "~Sent" { setflag "\\Seen"; fileinto "Sent"; } ---------------------------------------------------------------------- But it did not work, so maybe there is a trick I am not aware of. If I use the "Received" header and a regex, it works ---------------------------------------------------------------------- require ["fileinto","imap4flags","regex"]; if header :regex "Received" "for <[a-z]+~Sent(a)homebox.space>;" { setflag "\\Seen"; fileinto "Sent"; } ---------------------------------------------------------------------- This is working perfectly, but there is limitations, IMHO. - If the recipient delimiter is not compatible with a regex (e.g. "+"), then the script will probably fail. - Parsing every new email using a regular expression might not be the best option in term of system load. So, I finally use this: ---------------------------------------------------------------------- # Move automatically copied emails to the sent folder # And mark them as read require ["fileinto","imap4flags"]; if header :contains "Received" "~Sent" { setflag "\\Seen"; fileinto "Sent"; } ---------------------------------------------------------------------- My question is why the first one does not work? Does the email has been moved to the Sent folder, and dovecot sieve plugin is not able to find the email any more? Kind regards, André -- https://github.com/progmaticltd/homebox

lmtp service timeouting even after receiving full message

Isn't .\n always enough for dovecot to signal end of message? Because exim wrote full message to dovecot lmtp unix socket. Now the interesting this - exim does only one write() with 6585 bytes to write that message to lmtp. If exim needs more than one write() to do that (message is larger by some buffer) then it succeeds, dovecot accepts it. Could dovecot lmtp handling for single write() case be broken? dovecot 2.2.35 -- Arkadiusz Miśkiewicz, arekm / ( maven.pl | pld-linux.org )

Dovecot replication does not replicate subscription in shared mailboxes
by Ralf Becker 23 Mar '18

23 Mar '18

We use a pair of replicating Dovecot servers. If a user subscribes to a folder, shared by an other user, in one replica, that does not get replicated to the other node. Subscription of regular folders below INBOX seem to replicate correctly. Is that a general bug, a known problem or do we need to enable that somehow. Here's our configuration for the concerned namespace: namespace users { location = mdbox:%%h/mdbox:INDEXPVT=~/shared/%%u prefix = user/%%n/ separator = / subscriptions = no type = shared } I attached the full doveconf -n. Thanks for any points :) Ralf -- Ralf Becker EGroupware GmbH [www.egroupware.org] Handelsregister HRB Kaiserslautern 3587 Geschäftsführer Birgit und Ralf Becker Leibnizstr. 17, 67663 Kaiserslautern, Germany Telefon +49 631 31657-0

How to stop sieve processing to skip sieve_after scripts ?
by Mr Nicolas Belan 23 Mar '18

23 Mar '18

Hello the list, I am trying to achieve filter processing using sieve, but i am not sure I can do what I want. I want to let the user decide to use my filtering script (sieve_after) or not.According to the documentation, i am trying to stop processing in user sieve script, but processing continue. I am using dovecot 2.2 (CentOS). My sieve configuration is:plugin { sieve = /var/vmail/%d/%n/%n.sieve sieve_before = /etc/dovecot/sieve/global-before sieve_after = /etc/dovecot/sieve/global [...]} 'sieve' is the filter script created by users.

limit pop login per user and per minute
by Markus Eckerl 23 Mar '18

23 Mar '18

Hi, like I have written in the subject line I want to limit the pop login per user and per minute. Currently I am having several customers which are fetching their email with popcon (MS Exchange). This has never been a problem. But... They all have got the same "technician" which take care of their systems. The problem is, that he misconfigured the servers of these customers. In detail: their servers are trying to fetch email every 2 - 5 seconds. For every email address. In the past I contacted the technician and told him about his mistake. He was not very helpful and simply told me that he is doing the same configuration since several years at all of his customer servers. Without problems. It is up to me to fix my problem myself. Well, I googled a lot but all I found is to limit for a specific IP or for a secific account. Both is not what I am looking for. Maybe someone can give me a hint?

dovecot-uidlist is not up-to-date
by Dmitry Filonov 22 Mar '18

22 Mar '18

Hi, Am using dovecot-2.2.10-8 on Centos-7 and everything seemed to be totally fine for many years. Now am trying to migrate our on-premises mail server to the cloud and I had to get some statistics. I was doing that using the doveadm utility. Unfortunately I found that the numbers don't match if I check the real messages in my Maildirs. For some account doveadm was reporting number of messages but that account didn't have any messages stored at all. So I looked a bit further and found that doveadm utility reports data form indexes and indexes are built using dovecot-uidlist data. For quite some folders these files have way more data than actual mailbox has. For example, my personal Inbox has 569 messages but dovecot-uidlist has 716 entries. I don't know when and how that happened but this happens a lot on many different mailboxes on my server. I never touched dovecot-uidlist files outside of dovecot. I might have removed messages from Maildirs though, but not at this scale. Now the question is if there's any way to tell dovecot to rebuild dovecot-uidlist files using actual Maildir data. I don't want to remove dovecot-uidlist files as this triggers the whole mailbox being re-downloaded by the imap client. With some accounts having over 100Gb of mail this is too much of a hassle. I just need dovecot itself to fix it's data. Thanks, Fil -- Dmitry Filonov Network Analyst 300 Longwood Ave. Enders-1262.2 Boston, MA 02115 617-919-4702

"failed to map segment from shared object" in sieve pipe
by Dorian Taylor 22 Mar '18

22 Mar '18

Hello, I have encountered a problem attempting to run a program in a sieve pipe. The program is a Perl script that loads a number of binary (XS) modules at runtime. The program crashes, it appears, if it tries to load too many. The (non-Perl part of the) error message is "failed to map segment from shared object” — no additional information. Cryptic error messages like this have the odour of imposed resource restrictions, so I’m wondering if there are any on the pipe/filter/execute implementation (e.g. via program_client_run). Any configuration knobs I can twiddle? Any insights for debugging? PS this is the dovecot 2.2.22 (fe789d2), the one that ships with Ubuntu Xenial. Regards, -- Dorian Taylor Make things. Make sense. https://doriantaylor.com

Fwd: Fwd: Everything works except sending mail

(Sorry Aki I send it wrong the first time, I feel like a n00b) ---------- Forwarded message ---------- From: Armin Tangelder <a.tangelder(a)gmail.com> Date: Tue, Mar 20, 2018 at 3:25 PM Subject: Re: Fwd: Everything works except sending mail To: Aki Tuomi <aki.tuomi(a)dovecot.fi> Hi Aki, Mij postfix is sending and receiving mail. it might be an issue between Postfix and Dovecot. That is why I'm asking if one of the more experienced guru's ever did see something like this. A mail doesn't even reach the Postfix queue. And in paralel, I'm with this on postfix forums to take a look as well. But as Postfix probably is not discussed here I kept it to Dovecot only. But based on the dovecot -n you see anything wrong? Thnx, Armin Tangelder -- Very funny scotty, now beam down my clothes.
