doveadm move and create folders for the archive
by Michael Wagner 08 Dec '18

08 Dec '18

Hello guys, I'm on a few mailinglists, which I want to archive at the end of the year. I know the command to do this, but must I create the folders for the archive by myself or is there a switch for doveadm? I tested this, but it exits with an error about the missing mailbox. doveadm -D copy -u michael Archiv/debian-user/2018 mailbox debian-user since 365d error message: doveadm(michael): Debug: Effective uid=1000, gid=1000, home=/home/michael doveadm(michael): Debug: Namespace inbox: type=private, prefix=, sep=, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:~/Maildir:LAYOUT=fs doveadm(michael): Debug: fs: root=/home/michael/Maildir, index=, indexpvt=, control=, inbox=/home/michael/Maildir, alt= doveadm(michael): Error: Can't open mailbox 'Archiv/debian-user/2018': Mailbox doesn't exist: Archiv/debian-user/2018 Sorry for the long lines.

Segfault when using doveadm batch -A : kick
by Apollon Oikonomopoulos 08 Dec '18

08 Dec '18

Hi, Apparently the "kick" doveadm_cmd_ver2 struct lacks a .mail_cmd member pointing to an appropriate allocation function, causing a NULL pointer dereference when used via `doveadm batch`.

Different listeners with different config
by Peter Mogensen 07 Dec '18

07 Dec '18

Hi, I was wondering about the status on being able to create a dedicated listener in Dovecot with - say - extra features enabled. As an example... If I wanted to have Dovecot listening on port 144 with a slightly different set of auth mechanisms enabled. /Peter

argonid and dovecote
by Jerry 06 Dec '18

06 Dec '18

on a FreeBSD 11.2 amd64 machine, I am trying to get Dovecot 2.3.4 to play nice with "argonid" encryption. In the "10-auth.conf" file, I tried: auth_mechanisms = plain argon2id Upon restarting dovecot, I received an error message when attempting to actually it: auth: FATAL: Unknown authentication mechanism "ARGON2ID" Output from doveadm pw -l doveadm pw -l SHA1 SSHA512 BLF-CRYPT PLAIN HMAC-MD5 OTP SHA512 SHA RPA DES-CRYPT CRYPT SSHA MD5-CRYPT SKEY PLAIN-MD4 PLAIN-MD5 SCRAM-SHA-1 LANMAN SHA512-CRYPT CLEAR CLEARTEXT ARGON2I ARGON2ID SSHA256 NTLM MD5 PBKDF2 SHA256 CRAM-MD5 PLAIN-TRUNC SHA256-CRYPT SMD5 DIGEST-MD5 LDAP-MD5 I assume I am making a stupid mistake, but I do not know what it is. -- Jerry

Dovecot 2.3.4 crashing on Solaris 10 - "Panic: output stream is missing error handling"
by Fabian Fritz 06 Dec '18

06 Dec '18

Hi, I just compiled Dovecot for Solaris 10 and try to run it now. Other than setting a custom port, I did not add custom settings. When I tried running doveconf for the first time, it crashed immediately: doveconf -n # 2.3.4 (): /export/dovecot/etc/dovecot/dovecot.conf # OS: SunOS 5.10 sun4u~~ # Hostname: merlin service pop3-login { inet_listener pop3 { port = 1110 } } submission_max_mail_size = 0 doveconf: Panic: output stream is missing error handling doveconf: Error: Raw backtrace: 0xff01b3a8 -> 0xff063b04 -> 0x1673c -> 0x1797c -> 0x14478 Abort (core dumped) The same error appears when I run dovecot -F. Unfortunately I currently don't have access to the core dumps (I might do later), but I could run it with the Debugger with user process debugging enabled: (This is the part when it crashes.

Restricting sending mail to domain or group
by admin 06 Dec '18

06 Dec '18

Hi folks, has anybody a simple solution for the following request? I have a group alias (all(a)company.com) (1) Only company.com accounts should be able to send an email to everybody in that company via all(a)company.com. (2) - rather optional: refine the restrictions, e.g. two groups, grp1(a)company.com and grp2(a)company.com. Grp1 members should be able to send mails to grp2 but not vice versa. What else than sieve would keep dealing with that demands as simple as possible? Thanks in advance and sorry for abusing this list for this kind of „problem“ which is not a bug. Regards, -M

Error: Corrupted record in index cache file
by Orion Poplawski 05 Dec '18

05 Dec '18

With dovecot-2.2.36-3.el7.x86_64 we had a couple hours where mail_plugins did not properly include zlib for all of the needed services. This seems to have led to some corruption in our mdbox mailboxes. I've run doveadm force-resync on a number of users, but I'm still seeing messages like this: dovecot[13563]: imap(USER): Error: Corrupted record in index cache file /var/spool/imap/USER/mailboxes/INBOX/dbox-Mails/dovecot.index.cache: UID 67976: Broken physical size in mailbox INBOX: read(zlib(/var/spool/mail/USER/storage/m.1203)) failed: Cached message size smaller than expected (2978 < 8192, box=INBOX, UID=67976) Is there anything that can be done about this? Can I safely delete the dovecot.index.cache file? I'm hesitant to do so since I understand that the mdbox format uses the index to store mailbox information and deleting at least some index files is a destructive operation.

vacation script issue
by fins 05 Dec '18

05 Dec '18

Hello, I have a complete Postfix + Dovecot + openLDAP setup almost working, the only issue I have is the vacation script auto-reply that doesn't work properly. If I send an email to a user with the vacation filter enabled, the auto-reply is send to a local recipient with the same account name. So for example if I send a mail from test(a)xyz.com to test(a)example.com, the auto-reply is received on the test(a)example.com address instead of the test(a)xyz.com who's the original sender. Here's a log file: Dec 3 13:52:48 imap dovecot: lda(test(a)example.com): Debug: sieve: executing script from /var/mail/example.com/test/.dovecot.svbin Dec 3 13:52:48 imap dovecot: lda(test(a)example.com): sieve: msgid=< dovecot-sieve-1543841568-836314-0(a)imap.example.com>: discarding vacation response to auto-submitted message from <MAILER-DAEMON> Dec 3 13:52:48 imap dovecot: lda(test(a)example.com): sieve: msgid=< dovecot-sieve-1543841568-836314-0(a)imap.example.com>: stored mail into mailbox 'INBOX' Dec 3 13:52:48 imap postfix/pipe[6663]: D835A300E05: to=<test(a)example.com>, orig_to=<test(a)xyz.com>, relay=dovecot, delay=0.1, delays=0.03/0.01/0/0.06, dsn=2.0.0, status=sent (delivered via dovecot service) Can somebody help with this issue and/or point where to go for debugging?

Random issue on mailbox "assertion failed"

Hi, Since few weeks, I have regularly the issue below with some mailboxes - This is happening randomly. Users are complaining emails are not visible.

And what about the "dovecot-keywords" files in both folders? Do they match? The letter "a" seems to indicates that there is at least one non-standard flag defined in the source folder's keywords. By the way, can I assume you move messages only by using Thunderbird/IMAP and not by manipulating the file system?

dovecot and argon2 encryption
by Jerry 04 Dec '18

04 Dec '18

I am using a FreeBSD 11-2 amd/64 system with dovecot version 2.3.4 installed. I was playing around with different encryption schemes. doveadm pw -l SHA1 SSHA512 BLF-CRYPT PLAIN HMAC-MD5 OTP SHA512 SHA RPA DES-CRYPT CRYPT SSHA MD5-CRYPT SKEY PLAIN-MD4 PLAIN-MD5 SCRAM-SHA-1 LANMAN SHA512-CRYPT CLEAR CLEARTEXT SSHA256 NTLM MD5 PBKDF2 SHA256 CRAM-MD5 PLAIN-TRUNC SHA256-CRYPT SMD5 DIGEST-MD5 LDAP-MD5 There is no mention of "argon2" shown. Now, from the command line I can enter this command: ~ $ echo -n "Secret-Password" | argon2 somesalt Type: Argon2i Iterations: 3 Memory: 4096 KiB Parallelism: 1 Hash: e6432f595e999988c7c54c30d530b0fc7d9953510e5ccf295359258f4ea22a3d Encoded: $argon2i$v=19$m=4096,t=3,p=1$c29tZXNhbHQ$5kMvWV6ZmYjHxUww1TCw/H2ZU1EOXM8pU1klj06iKj0 0.039 seconds Verification ok However, this fails: doveadm pw -p "Secret-Password" -s argon2 Fatal: Unknown scheme: ARGON2 I have tried different ways to enter "argon2", but nothing works. Can someone tell me what I am doing wrong? Thanks :) -- Jerry

Hi there! I've installed dovecot for debian from the dovecot-repo in the latest Version 2:2.3.4-2~stretch And i still get this error-messages. dovecot[5817]: imap(user.name)<26484><nzUgti58YaEuffpZ>: Error: Log synchronization error at seq=4,offset=5748 for /var/lib/dovecot/db/indexes/Maildir/user.name/Trash/dovecot.index: Append with UID 202, but next_uid = 203 I read in the release-notes, that doveadm force-resync can solve this problem... But it didn't I ran the command on all Mailboxes, but deleting a message in Thunderbird (= moving it into Trash) causes the error above. Do you need further informations? BG jakob

Mailing list address harvested for spamming
by dovecot-e51＠deemzed.uk 03 Dec '18

03 Dec '18

Not to stir the pot, but I notice my email address has recently been harvested from this list for spamming purposes. This email address is unique and not used for anything else. I'd distinguish this from spam sent to the mailing list itself, which is obviously different. Is there anything further that could be done to prevent this? -- Dave

Relocate subfolders to different mount point
by Marc Roos 03 Dec '18

03 Dec '18

I would like to relocate the subfolders of the Sent folder to a different location. Now send messages mail is stored in mbox format at the location /home/users/testuser/mail/.Sent. I would like to store the subfolders Sent/2017 and Sent/2018 at the location /home/archive/users/testuser/.Sent.2017 and /home/archive/users/testuser/.Sent.2018 Is this even possible? I am using currently using this mail_location: mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u:CONTROL=~/mail/control:INDEX=/var/d ovecot/%u/index:LAYOUT=maildir++ /var/dovecot is on a ssd /var/spool/mail is on sda ~/mail is on sdb with these folders [@mail]# ls -ac1 .folderc .Drafts .foldera control .Trash.folderc .folderb .Sent .Sent.2018 .Trash

The tool metaphor is realistic. In my experience (which dates back to the 1980s), email ist a powerful tool, and people need to learn how to use it properly, with the appropriate software set.

Sieve broken after upgrade
by Pavel Stratil 02 Dec '18

02 Dec '18

Hi everyone, after switching to ubuntu (from debian) and running a newer dovecot --version 2.2.33.2 (d6601f4ec) i encountered a problem with configuring sieve. The mailserver has virtual maila accounts stored in /decrypted/%d/%n Prior, i used plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_before = /etc/dovecot/sieve/before.d } after the upgrade, I moved the sieve_before location on disk and changed this to plugin { sieve = file:~/sieve;active=~/.dovecot.sieve sieve_before = /var/lib/dovecot/sieve/before.d } only to see that sieve didnt forward e-mails anymore. Looking at the logs below, i suspect, that I didnt understood the meaning of sieve = file:~/sieve;active=~/.dovecot.sieve correctly: Dec 2 16:01:57 vao01 dovecot: lmtp(events(a)industra.space): Debug: Module loaded: /usr/lib/dovecot/modules/lib90_sieve_plugin.so Dec 2 16:01:57 vao01 dovecot: lmtp(events(a)industra.space): Debug: sieve: Pigeonhole version 0.4.21 (92477967) initializing Dec 2 16:01:57 vao01 dovecot: lmtp(events(a)industra.space): Debug: sieve: include: sieve_global is not set; it is currently not possible to include `:global' scripts.

I tried several combinations of configuring this, but I seem to miss some important point. Would you kindly help me get this right? Configs are attached. Thanks in advance, Pavel

Dovecot crash
by JCA 01 Dec '18

01 Dec '18

This happening when my Thunderbird client is trying to establish a connection with a Dovecot server. Some background first: 1) I am running Thunderbird 6.20.1 from a Linux client. 2) Other clients (e.g. Maildroid in my Android phone) do not have any issues. 3) The Dovecot software is version 2.2.9, running in a Linux server. 4) This may be the root of the problem: at some point, the Dovecot software was changed to version 2.3.1, and the reverted to 2.2.9. The crash started to appear when this reversion took place. My guess is that upgrading to 2.3.1 will eliminate this problem. However, in case that does not solve the problem, I would be grateful if anybody could throw some light into exactly what is going on here, and whether it can be fixed even without the need of upgrading to 2.3.1. What follows are the traces generated by Dovecot 2.2.9 when a connection is attempted from Thunderbird, with usernames and IP addresses disguised for privacy, and some blank lines inserted for readability: Nov 28 13:36:20 imap-login: Info: Login: user=<xyz>, method=PLAIN, rip=xxx.yyy.z zz.154, lip=aaa.bbb.ccc.7, mpid=29245, TLS, session=<q7jNhL97qQDMhbWa> Nov 28 13:36:20 imap(xyz): Panic: file mail-index-sync-keywords.c: line 227 (key words_update_records): assertion failed: (data_offset >= sizeof(struct mail_index_record)) Nov 28 13:36:20 imap(xyz): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so. 0(+0x65626) [0xb75ae626] -> /usr/lib/dovecot/libdovecot.so.0(+0x6569f) [0xb75ae6 9f] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0xb756180e] -> /usr/lib/dove cot/libdovecot-storage.so.0(mail_index_sync_keywords+0x707) [0xb76cb6b7] -> /usr /lib/dovecot/libdovecot-storage.so.0(mail_index_sync_record+0xf7) [0xb76cc167] - > /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_sync_map+0x2a4) [0xb76cd22 4] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_map+0x57c) [0xb76bcb9c ] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0xb7c2a) [0xb76b7c2a] -> /usr/lib /dovecot/libdovecot-storage.so.0(+0xb7daa) [0xb76b7daa] -> /usr/lib/dovecot/libd ovecot-storage.so.0(mail_index_open+0x114) [0xb76b7f54] -> /usr/lib/dovecot/libd ovecot-storage.so.0(index_storage_mailbox_open+0xab) [0xb76a808b] -> /usr/lib/do vecot/libdovecot-storage.so.0(+0x5a481) [0xb765a481] -> /usr/lib/dovecot/libdove cot-storage.so.0(+0x5a6f2) [0xb765a6f2] -> /usr/lib/dovecot/libdovecot-storage.s o.0(+0x7a017) [0xb767a017] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_o pen+0x26) [0xb767a1d6] -> dovecot/imap(client_open_save_dest_box+0x79) [0x805dca 9] -> dovecot/imap() [0x8052678] -> dovecot/imap(command_exec+0x32) [0x805d7a2] -> dovecot/imap() [0x805c746] -> dovecot/imap() [0x805c820] -> dovecot/imap(clie nt_handle_input+0x125) [0x805cad5] -> dovecot/imap(client_input+0x71) [0x805ce91 ] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x42) [0xb75c1292] -> /usr /lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xdb) [0xb75c22cb] -> /usr/lib/ dovecot/libdovecot.so.0(io_loop_run+0x48) [0xb75c0cd8] -> /usr/lib/dovecot/libdo vecot.so.0(master_service_run+0x2d) [0xb756728d] -> dovecot/imap(main+0x2bf) [0x 8066fef] -> /lib/libc.so.6(__libc_start_main+0xe6) [0xb73cfdb6] Nov 28 13:36:20 imap(xyz): Fatal: master: service(imap): child 29245 killed with signal 6 (core dumps disabled) Nov 28 13:36:20 imap-login: Info: Login: user=<xyz>, method=PLAIN, rip=xxx.yyy.z zz.154, lip=aaa.bbb.ccc.7, mpid=29247, TLS, session=<xPzShL97lADMhbWa> Nov 28 13:36:21 imap(xyz): Panic: file mail-index-sync-keywords.c: line 227 (key words_update_records): assertion failed: (data_offset >= sizeof(struct mail_inde x_record)) Nov 28 13:36:21 imap(xyz): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so. 0(+0x65626) [0xb7757626] -> /usr/lib/dovecot/libdovecot.so.0(+0x6569f) [0xb77576 9f] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0xb770a80e] -> /usr/lib/dove cot/libdovecot-storage.so.0(mail_index_sync_keywords+0x707) [0xb78746b7] -> /usr /lib/dovecot/libdovecot-storage.so.0(mail_index_sync_record+0xf7) [0xb7875167] - > /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_sync_map+0x2a4) [0xb787622 4] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_map+0x57c) [0xb7865b9c ] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0xb7c2a) [0xb7860c2a] -> /usr/lib /dovecot/libdovecot-storage.so.0(+0xb7daa) [0xb7860daa] -> /usr/lib/dovecot/libd ovecot-storage.so.0(mail_index_open+0x114) [0xb7860f54] -> /usr/lib/dovecot/libd ovecot-storage.so.0(index_storage_mailbox_open+0xab) [0xb785108b] -> /usr/lib/do vecot/libdovecot-storage.so.0(+0x5a481) [0xb7803481] -> /usr/lib/dovecot/libdove cot-storage.so.0(+0x5a6f2) [0xb78036f2] -> /usr/lib/dovecot/libdovecot-storage.s o.0(+0x7a017) [0xb7823017] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_o pen+0x26) [0xb78231d6] -> dovecot/imap(client_open_save_dest_box+0x79) [0x805dca 9] -> dovecot/imap() [0x8052678] -> dovecot/imap(command_exec+0x32) [0x805d7a2] -> dovecot/imap() [0x805c746] -> dovecot/imap() [0x805c820] -> dovecot/imap(clie nt_handle_input+0x125) [0x805cad5] -> dovecot/imap(client_input+0x71) [0x805ce91 ] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x42) [0xb776a292] -> /usr /lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xdb) [0xb776b2cb] -> /usr/lib/ dovecot/libdovecot.so.0(io_loop_run+0x48) [0xb7769cd8] -> /usr/lib/dovecot/libdo vecot.so.0(master_service_run+0x2d) [0xb771028d] -> dovecot/imap(main+0x2bf) [0x 8066fef] -> /lib/libc.so.6(__libc_start_main+0xe6) [0xb7578db6] Nov 28 13:36:21 imap(xyz): Fatal: master: service(imap): child 29247 killed with signal 6 (core dumps disabled)

Replacing email envelope
by jon.sp2＠wp.pl 30 Nov '18

30 Nov '18

Hi, Could you please advice how I can replace envelope of a message received on my server? Best would be using sieve. Simple case - email A(a)example.com receives message, which I'd like to repack into new envelope (I want to have control what values in the envelope will be there - from, to, replay-to et.c) and send to B(a)test.com . At first I wanted to use editheader extension, but it is not allowing me to modify From or To values as far as I can tell. Another idea was to use envelope, but I don't see any way of editing values. Only reading. Now, I am thinking of writing script and from sieve it will be passed there, where I'll do message parsing and send new message using mutt or something similar. Frankly speaking I suppose there is much better solution to that and I'd appreciate any advice on the topic. Thanks, Jon

rspamd / imapsieve script is not executed/called
by Michael Ludwig 30 Nov '18

30 Nov '18

Hi to all of you, as I am struggling around with this a week or so I'm afraid I have to ask for help here. The problem is sitting right in front of the computer, as most of the time. ;-) So let me explain: Dovecot is working properly for IMAP with LE certificates, so I thought it's time to continue with Christoph Haas tutorial primarily and other blogs and tutorials for setting up the server. Next part would be to get rspamd learning what mails the user puts into junk folder. I followed the tutorial, but it will not work. Also I tried to get into debug mode, but I feel that dovecot is not really logging too much.

Best way of merging mbox files
by Marc Roos 30 Nov '18

30 Nov '18

When concatenating mbox files like described here https://xaizek.github.io/2013-03-30/merge-mbox-mailboxes/. You will end up with an 'unsorted' mbox file. Is this going to be a problem esspecially when they are large >2GB's and new emails will be written to it? The email client nicely sorts the message from folder A "foldera 5 last" as last, but of course the mbox is not like this. Is there a better solution for merging files? Having: A folder A with messages: From Subject Received Size test foldera 1 16:18 665 B test foldera 2 16:18 665 B test foldera 3 16:18 665 B test foldera 4 16:18 665 B test foldera 5 last 16:29 670 B A folder B with messages: From Subject Received Size test folderb 1 16:23 665 B test folderb 2 16:24 665 B test folderb 3 16:24 665 B test folderb 4 16:24 665 B test folderb 5 16:24 665 B [@ mail] cat .foldera .folderb > .folderc Getting a folder C with messages: From Subject Received Size test foldera 1 16:18 665 B test foldera 2 16:18 665 B test foldera 3 16:18 665 B test foldera 4 16:18 665 B Mail System Internal Data DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA 16:19 454 B test folderb 1 16:23 665 B test folderb 2 16:24 665 B test folderb 3 16:24 665 B test folderb 4 16:24 665 B test folderb 5 16:24 665 B test foldera 5 last 16:29 670 B

"merging" folders Sent-Items Sent-Messages Sent
by Marc Roos 29 Nov '18

29 Nov '18

I have a running server and would like to clean up a bit, and merge sent folders and trash folders etc. Is this best done via the mailbox alias plugin like mentioned here? Or is there a better way? I prefer to have one folder listed at the client, and not "Unfortunately it also means that some clients will download the same mails to local cache multiple times." https://wiki2.dovecot.org/Plugins/MailboxAlias dovecot-2.2.10-8.el7.x86_64 CentOS Linux release 7.5.1804 (Core)

Hi, i'm quite often getting this error: Error: fts_solr: Lookup failed: 414 URI Too Long Most web servers are limiting URI length to 8192 characters. Why not to use POST instead of GET when communicating with Solr? Solr is able to handle this ok, also see: https://dzone.com/articles/solr-select-query-get-vs-post azur

determine why mail clients download mails 2nd time
by Poliman - Serwis 29 Nov '18

29 Nov '18

I have strange problem. In last Friday I had a problem with dovecot. It didn't see directories with mailboxes in /var/vmail. Somehow it crashed because probably two things (a lot of this type of lines in mail.err file): *Nov 23 07:05:02 s1 dovecot: lda(poli(a)poli.li <poli(a)poli.li>): Error: User initialization failed: Initializing mail storage from mail_location setting failed: mkdir(/var/vmail/poli.li/poli/Maildir <http://poli.li/poli/Maildir>) failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing +w perm: /var/vmail, dir owned by 0:0 mode=0755)* and maybe *Nov 12 09:27:59 s1 dovecot: imap(artur(a)firmastanaszek.pl <artur(a)firmastanaszek.pl>): Error: Corrupted index cache file /var/vmail/firmastanaszek.pl/artur/Maildir/dovecot.index.cache <http://firmastanaszek.pl/artur/Maildir/dovecot.index.cache>: Broken MIME parts for mail UID 559 in mailbox INBOX: Cached MIME parts don't match message during parsing: Cached header size mismatch (parts=)Nov 12 09:27:59 s1 dovecot: imap(artur(a)firmastanaszek.pl <artur(a)firmastanaszek.pl>): Error: unlink(/var/vmail/firmastanaszek.pl/artur/Maildir/dovecot.index.cache <http://firmastanaszek.pl/artur/Maildir/dovecot.index.cache>) failed: No such file or directory (in mail-cache.c:28)* and after this event probably all mailboxes download again all emails from 1.11 to 22.11. They were duplicated in mail clients. -- *Pozdrawiam / Best Regards* *Piotr Bracha*

Hi! Just udated my Fedora dovecot to version 2.2.36 and found that after the update dovecot will fail all LDAP logins after slapd has been restarted during the logrotate. Restarting dovecot fixes the problem. Is there a bug preventing dovecot to reopen the LDAP session when it fails? Best Dag

Installing on Mojave, with Homebrew and mysql
by James Brown 25 Nov '18

25 Nov '18

I’m using Homebrew to install Dovecot on Mojave, but have to modify the formula to add ‘--with-mysql’. Unfortunately compiling always fails with: checking for mysql_config... NO checking for mysql_init in -lmysqlclient... no configure: error: Can't build with MySQL support: libmysqlclient not found I added: ENV['LD']="-L/usr/local/opt/mysql(a)5.7/lib" to the ‘def install’ section of the formula, but it still fails. config.log shows: … KRB5_LIBS='' LD='-L/usr/local/opt/mysql(a)5.7/lib/' LDAP_LIBS=‘' … And mysqlclient is here: $ locate mysqlclient /usr/local/Cellar/mysql(a)5.7/5.7.24/lib/libmysqlclient.20.dylib /usr/local/Cellar/mysql(a)5.7/5.7.24/lib/libmysqlclient.a /usr/local/Cellar/mysql(a)5.7/5.7.24/lib/libmysqlclient.dylib /usr/local/Cellar/mysql(a)5.7/5.7.24/lib/pkgconfig/mysqlclient.pc I changed the formula to: ENV['LD']="-L/usr/local/Cellar/mysql(a)5.7/5.7.xn--24/lib/-236c And still get the same thing. Any suggestions? Thanks, James.

Testing validity of Dovecot config in a script
by Ralph Seichter 24 Nov '18

24 Nov '18

While trying to determine a given configuration is valid from within a script, I found that the following works with Dovecot version 2.3.2.1: #!/usr/bin/env bash doveconf -n >/dev/null || echo "Config is invalid" However, the return code is not documented in the doveconf manual page, and I wonder if the observed behaviour can be relied on? Is this the recommended method to test configuration validity? Personally, I'd like to have a dedicated call available. Something like # Proposal: "-t" for "test config" doveconf -t [-c config-file] with documented return codes would be ideal. -Ralph

Problems after upgrading to 2.3.2.1
by Joel Dahl 23 Nov '18

23 Nov '18

Hi, I've just upgraded dovecot from 2.2.35 to 2.3.2.1 on my mail server and noticed something odd. My mail clients (mutt and Apple mail) both stopped seeing new mail in my mailboxes. For example, ~/Maildir/mailinglist1/new has 5 new mails. In mutt, vieweing the list of mailboxes mutt reports 0 new mail for "mailinglist1". Opening up the actual mailbox in mutt reveals the 5 new mails. Going back to the list of mailboxes, mutt now correctly reports 5 unread mails. Waiting a few hours, and about 10 new mails have arrived, but mutt still says 5 unread. This is the same for every mailbox. As a test I deleted the index files for a specific mailbox and restarted dovecot. But it didn't help. I use procmail to deliver my mail into the Maildir folders, if that matters. Any ideas? I haven't changed my dovecot configuration in a long time, except for adding ssl_dh after the upgrade. My config is below: auth_mechanisms = plain login imap_client_workarounds = delay-newmail tb-extra-mailbox-sep tb-lsub-flags info_log_path = /var/log/dovecot-info.log log_path = /var/log/dovecot.log mail_location = maildir:~/Maildir mail_privileged_group = mail maildir_very_dirty_syncs = yes passdb { args = session=yes dovecot driver = pam } protocols = imap service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } ssl = required ssl_cert = </path/to/cert.pem ssl_dh = # hidden ssl_key = # hidden userdb { driver = passwd } -- Joel

doveadm dsync-server doesn't use user parameter?
by Harald Leithner 23 Nov '18

23 Nov '18

Hi, I tried to migrate my dovecot 2.2 to a new server with a other storage configuration and dovecot 2.3. New (and old) Server uses mysql for user information I use the following storage settings mail_home = /storage1/vmail/%{userdb:path} mail_location = mdbox:/storage1/fast/%{userdb:path}:FULLDIRNAME=iTrNiCs-DBOx-mAiLs:INDEX=/storage1/indexes/vmail/%{userdb:path}:ALT=/storage1/slow/%{userdb:path}:VOLATILEDIR=/tmp/%{userdb:path} userdb:path is generated by the mysql query and ends in something like "2000/6" SQL: CONCAT(u.idAccount, '/', u.idUser) AS userdb_path If I login with imap dovecot is creating the INBOX on the correct path /storage1/fast/2000/6/mailboxes/INBOX btw. it creates a link to dbox-alt-root but without creating the target directory is this expected? Now if I start doveadm backup -u <username> remote:mailstore2 it ignores it seams that dsync-server doesn't make a database query and doesn't use the userdb_path field. It only uses /storage1/fast/mailboxes/INBOX as path. Is this a problem with my configuration? thx --- doveconf -n # 2.3.3 (dcead646b): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.3 (f018bbab) # OS: Linux 4.15.18-7-pve x86_64 Debian 9.6 zfs # Hostname: mailstore2 auth_cache_negative_ttl = 1 secs auth_cache_size = 10 M auth_cache_ttl = 1 secs auth_master_user_separator = * auth_mechanisms = PLAIN LOGIN APOP auth_verbose = yes default_client_limit = 600 default_vsz_limit = 512 M dict { lastlogin = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext sqlacl = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } disable_plaintext_auth = no first_valid_gid = 1001 first_valid_uid = 1001 hostname = mailstore2 imap_hibernate_timeout = 1 mins imap_id_log = * imap_id_send = * imap_idle_notify_interval = 10 mins imap_logout_format = bytes=%i/%o instance_name = mailstore2 last_valid_gid = 1001 last_valid_uid = 1001 lda_original_recipient_header = X-LDA-Original-To lmtp_rcpt_check_quota = yes login_greeting = ITronic Mail Store login_trusted_networks = 172.22.14.0/24 mail_cache_min_mail_count = 5 mail_gid = vmail mail_home = /storage1/vmail/%{userdb:path} mail_location = mdbox:/storage1/fast/%{userdb:path}:FULLDIRNAME=iTrNiCs-DBOx-mAiLs:INDEX=/storage1/indexes/vmail/%{userdb:path}:ALT=/storage1/slow/%{userdb:path}:VOLATILEDIR=/tmp/%{userdb:path} mail_plugins = lazy_expunge acl quota mail_log notify mail_prefetch_count = 100 mail_server_admin = mailto:postmaster@example.com mail_server_comment = Mail System mail_shared_explicit_inbox = yes mail_uid = vmail 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 vacation-seconds mdbox_preallocate_space = yes namespace { hidden = yes list = no location = mdbox:/storage1/fast/%{userdb:path}:MAILBOXDIR=expunged:LISTINDEX=expunged.list.index:FULLDIRNAME=iTrNiCs-DBOx-mAiLs:INDEX=/storage1/indexes/vmail/%{userdb:path}:ALT=/storage1/slow/%{userdb:path}:VOLATILEDIR=/tmp/%{userdb:path} prefix = "#EXPUNGED/" subscriptions = no type = private } namespace { list = children location = mdbox:%%h/mdbox prefix = "#Users/%%u/" separator = / subscriptions = yes type = shared } namespace inbox { hidden = no inbox = yes location = mailbox Archvie { special_use = \Archive } mailbox Drafts { special_use = \Drafts } mailbox Sent { special_use = \Sent } mailbox Spam { special_use = \Junk } mailbox Trash { special_use = \Trash } prefix = separator = / subscriptions = yes type = private } passdb { args = /etc/dovecot/master-users driver = passwd-file master = yes result_success = continue-ok } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { acl = vfile acl_shared_dict = proxy::sqlacl last_login_dict = proxy::lastlogin last_login_key = #

Anyways, seems the problem was that the LDAP user_attrs is missing commas, and the mailRoutingAddress is used wrong, so the correct syntax would be: user_attrs = \ mailRoutingAddress=user, \ =uid=vmail, \ =gid=mail, \ =home=/var/mail/%d/%n, \ =quota_rule=*:bytes=%{ldap:departmentNumber} Aki > On 22 November 2018 at 15:29 Vincent Seynhaeve <vlamsdoem(a)gmail.com> wrote: > > > doveadm quota recalc -u test doesn't give anything. > Bellow the ouput of the `doveconf -n` and `doveadm user test` > > doveconf -n > # 2.2.10: /etc/dovecot/dovecot.conf > # OS: Linux 3.10.0-862.11.6.el7.x86_64 x86_64 CentOS Linux release 7.5.1804 > (Core) xfs > auth_debug = yes > auth_mechanisms = plain login > auth_verbose = yes > mail_debug = yes > mail_gid = mail > mail_home = /var/mail/%d/%n > mail_location = maildir:/var/mail/%d/%n/Maildir > mail_plugins = " quota" > mail_uid = vmail > 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 > mbox_write_locks = fcntl > 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/dovecot-ldap.conf.ext > driver = ldap > } > plugin { > quota = maildir:User quota > quota_grace = 10%% > quota_rule2 = Trash:storage=+100M > quota_status_nouser = DUNNO > quota_status_overquota = 552 5.2.2 Mailbox is full > quota_status_success = DUNNO > sieve = ~/.dovecot.sieve > sieve_dir = ~/sieve > } > protocols = imap pop3 lmtp sieve > service auth { > unix_listener /var/spool/postfix/private/auth { > group = postfix > mode = 0666 > user = postfix > } > unix_listener auth-userdb { > group = mail > mode = 0600 > user = vmail > } > } > service imap-login { > inet_listener imap { > port = 0 > } > } > service managesieve-login { > inet_listener sieve { > port = 4190 > } > } > service pop3-login { > inet_listener pop3 { > port = 0 > } > inet_listener pop3s { > port = 0 > } > } > ssl = required > ssl_cert = </etc/pki/tls/certs/imap.example.com.crt > ssl_key = </etc/pki/tls/private/imap.example.com.key > userdb { > args = /etc/dovecot/dovecot-ldap.conf.ext > driver = ldap > } > protocol lda { > mail_plugins = " quota sieve" > } > protocol imap { > mail_plugins = " quota imap_quota" > } > > > > > doveadm user test > field value > uid vmail > gid mail > home /var/mail//test > mail maildir:/var/mail//test/Maildir > mailRoutingAddress user =uid=vmail =gid=mail =home=/var/mail//test > =quota_rule=*:bytes=1M > > > Le jeu. 22 nov. 2018 à 14:18, Aki Tuomi <aki.tuomi(a)open-xchange.com> a > écrit : > > > Can you provide output of `doveconf -n` and `doveadm user test`?

Same emails appearing multiple time after upgrade to version 2.33

Hi, I have update today dovecot and dovecot pigeonhole to the latest version available on my centos 7. It’s a small email servers with postfix/amavisd/clamav/spamasssin. I had dovecot for IMAP/POP3 with spam plugins to store spam message automatically into the spam folder. After the upgrade, I was noticed by some of my users that they have in their message the same message appearing 2,3 even 10 times. I had the same behavior when using roundecube I was able to stop this after removing pigeonhole rpm (removing/disabling the config was not enough). Would appreciate your help to understand what is wrong with my config.

Multi-server but small scale
by Daniel Miller 21 Nov '18

21 Nov '18

I have a small but critical server that supports our group. As a single server - it's obviously a single-point-of-failure for lots of things. As I just experienced...again. It was a lot more fun building systems from components when I was younger... Previously 3rd-party hosted solutions didn't look attractive for several reasons...but I'm seeing prices now for cloud virtual machines that are stupid cheap. Even if they wind up being limited speed & availability - it would seem they'd be a lot better than nothing! So I'm considering having at least one backup server for various services - obviously that includes mail. So now I have to wonder about the backend. And while I think I'm reasonably current with networked file systems (not distributed or cluster) I haven't played with replication for a quite a while. For this particular usage (I'm envisioning two servers total) - is there a need/reason to use any form of networked/distributed/cluster file storage? Or would this be accomplished via "pure" Dovecot - dsync replication would keep things updated between the servers and director would handle the connections? So with identically configured SMTP servers, passing to the local LMTP agents, the file system would be "purely local" with no NFS or other interconnection? -- Daniel

analysing of dmarc report
by Poliman - Serwis 21 Nov '18

21 Nov '18

I have a problem with understanding dmarc reports and some features. I attach two reports. First one come from google.com, second one from tumieszkamy.pl. On my server is dns zone of domain kamir-transport.pl but whole mail service is deployed on Google - in dns zone MX points to Google and there are all mailboxes, aliases etc. Last time I have configured dkim and dmarc policies and I got two reports. Honestly I don't know why two, from two different providers - google.com and tumieszkamy.pl. Moreover in report originating from google I see IP of my server [which fails spf and dkim policies] and I don't understand why this IP is evaluated? Second thing which I don't understand is second report which I got from tumieszkamy.pl. SPF record in dns zone of domain kamir-transport.pl was looking like below (now I changed it to slightly different): *v=spf1 mx include:_spf.google.com <http://spf.google.com> -all* Does anybody could help uderstand these things? -- *Pozdrawiam / Best Regards* *Piotr Bracha*

Quota in MySql Dict not recalculate automatic
by SUnsin＠gv-bayern.de 20 Nov '18

20 Nov '18

Hi, I have a working Installation with: Ubuntu 16.04 LTS Dovecot 2.2.22 MySql 5.7.24 Postfixadmin 3.2 Apache 2.4.18 Rainloop 1.12.1 I manage the E-Mail Accounts with postfixadmin in a MySql-DB. Also I use quotas with Quota Backend postfixadmin-DB (dict). Everything works fine. Now I installed a new Server with the following Versions and migrate the Configs to the new System. Ubuntu 18.04 LTS Doveot 2.2.33 MySQL 5.7.24 Postfixadmin 3.2 Apache 2.4.18 Rainloop 1.12.1 The Problem is now: When I receive a E-Mail, the quota will not Update (recalculate) automatical in the MySql-DB from Dovecot. In the old System there execute the SQL Statement after receiving a E-Mail, for example: UPDATE quota2 SET bytes=bytes+3076,messages=messages+1 WHERE username = <E-Mail Address> On the new System with the newer Dovecot Version, the Statement never comes after receive an E-Mail. With Dovecot Version 2.3 on the old System with Ubuntu 16.04, everything works fine with the same config. Is a BUG in the Dovecot Version 2.2.33 possible? Can everbody help me?

Update virtual folders via doveadm?
by Daniel Miller 20 Nov '18

20 Nov '18

I'm trying to have my server maintain it's FTS indexes reasonably current at all times. From prior threads, and based on my namespace configuration, I have the following hourly cronjob: doveadm index -A -q '*' doveadm index -A -q 'shared/*' doveadm index -A -q 'virtual/*' This seems to work just fine to maintain the FTS (Solr). However - as I understand it Dovecot's virtual folders are not updated with new mails until they are accessed by a client. Therefore the above command sequence would work fine for my default namespace and the shared - but the virtual namespace won't actually be current. So... Would a command such as: doveadm mailbox status -A messages virtual/* Be appropriate to run prior to the virtual/* FTS indexing? -- Daniel

IMAP Limitations with Outlook 2013?
by Robert Adkins 19 Nov '18

19 Nov '18

Good Day! I have a fairly new user on my network that has, over about 10 months, created in root inbox and nested sub-folders totaling over 900 individual folders. In the past few weeks, newly created folders will be visible in Outlook 2013, but when an email is moved into that folder, it is no longer visible. I can ssh into the server, drill down to that sub-folder and see the email in the folder AND it is also available to be seen without issue in Thunderbird. I know this is a longshot, but if there is some feature that I haven't found in Dovecot to force Outlook to synchronize with all the folders/sub-folders, please let me know. Beyond that. With this particular users habits, over the next 5 years, there could be nearly 10,000 folders/sub-folders. Does anyone know if this will create any problems with Dovecot or is this JUST a Microsoft software problem? -- Best Regards, Robert Adkins IT Manager/Tool Designer Impel Industries, Inc. 586-254-5800

macOS Mojave: setgroups(501) failed: Too many extra groups
by Heiko W. Rupp 18 Nov '18

18 Nov '18

Hello, I have recently upgraded to macOS 10.14 (Mojave) and am running into an issue where one use can no longer log into dovecot via imap. Log shows Oct 11 08:10:27 imap(hwr)<12659><YpC/0+133+EAAAAAAAAAAAAAAAAAAAAB>: Fatal: setgroups(501) failed: Too many extra groups and indeed, the user is in 17 groups, which is more than NGROUPS_MAX (16). Another user with << 16 groups can log in fine. Unfortunately it is not (easily) doable to reduce the number of groups, as macOS seems to set them internally. Is there a config option that I am missing to work around this? Looking at the source, I see this is handled in src/lib/restrict-access.c::fix_groups_list(), where above the call to setgroups() a gid_list2 is constructed. I wonder if one could have a config option to prevent adding all those extra groups, which then make the call to setgroups() fail Any help appreciated Heiko -- hwr(a)pilhuhn.de m:0179/207 4919 b:http://pilhuhn.blogspot.com

Re: Issue sharing folders with Thunderbird

Hi Aki I see what you are saying, and no I don’t believe so. I’m using typical /etc/passwd for the user db. I reviewed https://wiki.dovecot.org/UserDatabase/ExtraFields <https://wiki.dovecot.org/UserDatabase/ExtraFields> but I’m not clear on how to actually return system_user userdb attribute. I also have set mail_user_groups = sharedusers in dovecot.conf and then in /etc/group put all the users with mailboxes into the sharedusers group. I can see why that wouldn’t work if the above is not set. Can you point me in the right direction on how to pass that information?

Mail slowed down to a crawl...
by StarionTech (IMAP) 16 Nov '18

16 Nov '18

Been moving along just fine for a couple years now, then in the last two days, email has slowed to a crawl. Retrieving email via IMAP is very slow, progress bar in the mail client shows that it is downloading messages almost constantly, like it never closes the connection, or it’s getting the messages very slowly. The server that dovecot/postfix is on has also bogged down to a crawl. The postfix queue is sitting with hundreds of queued up good customer email. It’s almost acting like dovecot is not getting the messages from postfix, or they’re being delayed for some reason. How to approach fixing this? Jeff J.

Hi, we upgraded our servers from version 2.2.13 to 2.2.27. After the upgrade we notice a 10x increase in traffic with the nfs storage an errors like this in the logfile: Nov 12 09:48:16 mail dovecot: imap(...): Error: Corrupted index cache file /.../dovecot.index.cache: invalid record size Nov 12 09:48:16 mail dovecot: imap(...): Error: unlink(/.../dovecot.index.cache) failed: No such file or directory (in mail-cache.c:29) Nov 12 09:48:16 mail dovecot: imap(...): Error: Corrupted index cache file /.../dovecot.index.cache: invalid record size Nov 12 09:48:16 mail dovecot: imap(...): Error: Broken file /.../dovecot-uidlist line 8: Invalid data: Is this normal ?

dovecot 2.2/openssl 1.0 vs dovecot 2.3/openssl 1.1.1 ssl regression
by Arkadiusz Miśkiewicz 15 Nov '18

15 Nov '18

Hi. I'm considering dovecot migration from 2.2.36 run with openssl 1.0.2o to dovecot 2.3.3 run with openssl 1.1.1. Currently I have both variants running with identical configs and certs (the only differences are due to config syntax changes in dovecot 2.3), so for example on both I have: ssl_ca = </etc/openssl/certs/wildcard_ca.pem (this file contains single intermediate certificate of my CA) ssl_cert = </etc/openssl/certs/wildcard_crt.pem (this contains single cerificate for my *.example.com domain) ssl_key = # hidden, use -P to show it (and one key) No alt certs in use. Chain is: - CA trusted by clients (this certificate isn't provided by my dovecot, it's not needed) - wildcard_ca.pem - intermediate CA - wildcard_crt.pem - wildcard certificate for my *.example.com domain dovecot 2.2.36 behaviour is to provide wildcard_ca.pem and wildcard_crt.pem to the client - that behaviour is OK. Client has full trust chain. dovecot 2.3.3 provides only wildcard_crt.pem certificate to the client which is a big problem because missing wildcard_ca.pem (intermediate certificate) breaks chain and client is not able to verify trust chain. Testing is done with simple: openssl s_client -connect my.example.com:143 -starttls imap -servername my.example.com -showcerts 2.3.x announcements and upgrade wiki mention no such behaviour change, so I assume it is a regression. Now doing cat wildcard_ca.pem >> wildcard_crt.pem solves the problem and dovecot starts providing both certs to clients but if that's the proper way of solving this issue then what's the point of having ssl_ca config setting? Ideas? -- Arkadiusz Miśkiewicz, arekm / ( maven.pl | pld-linux.org )

FETCH BODY vs FETCH BODYSTRUCTURE + FETCH BODY.PEEK
by Alessio Cecchi 15 Nov '18

15 Nov '18

Hello, we are developing a web page, for a ticket system, to show the email messages ordered by the biggest attachments size present in an IMAP folder, with a pagination of 100 messages per page. Each raw represents a message with "DATE, FROM, SUBJECT, the preview (the first 500 chars of the text/html of the messsage) and the list of the attachments (name + size) it contains. The problem is that the page load is VERY slow because we fetch the entire BODY of all 100 messages, in order to get the preview and the attachments name and size. Now, considering that each messages can contain up to 50 MB of attachments, we risk to download 5000MB from IMAP for every page. An option might be to perform two FETCH for each message: - one fetch with just the BODYSTRUCTURE (where we can get the attachments name and size and the text/html parts). - one fetch with the body parts (BODY.PEEK[]) we need to build the preview (text + html). We are wondering if there is a single FETCH command to get the text and html parts (needed to build the preview) with only the name and the size of the attachments without downloading the entire message. Thanks. -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice

Dovecot proxy: per user/domain 'namespace/inbox/prefix' from MySQL
by Adi Pircalabu 15 Nov '18

15 Nov '18

As a way to try and avoid using "prefix = INBOX." ad infinitum for the inbox namespace, I'm looking for ways to move on to "prefix =" for new mail accounts, and grandfather the existing ones. Previously running Courier-IMAP, now Dovecot, I looked at https://wiki.dovecot.org/Namespaces#Backwards_Compatibility:_Courier_IMAP and decided it's too risky to go down that path and use namespace compat, with so many IMAP clients out there the scope of testing is huge and the outcome is uncertain and not worth it. After reading https://wiki.dovecot.org/Namespaces#Per-user_Namespace_Location_From_SQL I thought I might be able to overwrite the server configuration per user returning 'namespace/inbox/prefix' value from SQL. Here's the setup I attempted, briefly: 1. Client connects to the Dovecot proxy, which authenticates the user and proxies to the backend using a query like this in /etc/dovecot/conf.d/dovecot-sql.conf.ext: driver = mysql connect = <connection_string> password_query = SELECT NULL AS password, 'Y' as nopassword, host, 'any-cert' as 'starttls', 'Y' AS proxy FROM mailbox WHERE email = '%u' AND disabled_smtpauth=0 Works a treat. 2. Next, I'm trying to add the prefix lookup in the picture. In the same file I've added: user_query = SELECT ns_inbox_prefix AS 'namespace/inbox/prefix' FROM mailbox WHERE email = '%u' AND disabled_smtpauth=0 3. The mailbox table schema reads: CREATE TABLE `mailbox` ( `id` int(11) unsigned NOT NULL AUTO_INCREMENT, `email` varchar(255) NOT NULL DEFAULT '', `password` varchar(255) NOT NULL DEFAULT '', `clear_password` varchar(255) NOT NULL DEFAULT '', `name` varchar(255) NOT NULL DEFAULT '', `host` varchar(32) DEFAULT NULL, `port` varchar(32) DEFAULT NULL, `ns_inbox_prefix` varchar(255) NOT NULL DEFAULT '', `lastlog_remote_ips` bigint(20) unsigned NOT NULL DEFAULT 0, `curlog_remote_ips` bigint(20) unsigned NOT NULL DEFAULT 0, `disabled_smtpauth` tinyint(1) NOT NULL DEFAULT 0, `last_modified` timestamp NOT NULL DEFAULT current_timestamp() ON UPDATE current_timestamp(), PRIMARY KEY (`id`), UNIQUE KEY `email` (`email`) ) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=latin1; The 2 queries above return: MariaDB [postfix]> SELECT NULL AS password, 'Y' as nopassword, host, 'any-cert' as 'starttls', 'Y' AS proxy FROM mailbox WHERE email = 'adi2(a)0aditest.local' AND disabled_smtpauth=0; +----------+------------+----------------+----------+-------+ | password | nopassword | host | starttls | proxy | +----------+------------+----------------+----------+-------+ | NULL | Y | 192.168.123.24 | any-cert | Y | +----------+------------+----------------+----------+-------+ 1 row in set (0.00 sec) MariaDB [postfix]> SELECT ns_inbox_prefix AS 'namespace/inbox/prefix' FROM mailbox WHERE email = 'adi2(a)0aditest.local' AND disabled_smtpauth=0; +------------------------+ | namespace/inbox/prefix | +------------------------+ | | +------------------------+ 1 row in set (0.00 sec) After reloading dovecot service with auth_debug = yes are the maillog for an IMAP session: Nov 15 12:43:48 proxy1 dovecot: auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth Nov 15 12:43:48 proxy1 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/lib20_auth_var_expand_crypt.so Nov 15 12:43:48 proxy1 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_mysql.so Nov 15 12:43:48 proxy1 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so Nov 15 12:43:48 proxy1 dovecot: auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.dat Nov 15 12:43:48 proxy1 dovecot: auth: Debug: auth client connected (pid=7527) Nov 15 12:43:53 proxy1 dovecot: auth: Debug: client in: AUTH#0111#011PLAIN#011service=imap#011secured#011session=AorrLqp6drgAAAAAAAAAAAAAAAAAAAAB#011lip=::1#011rip=::1#011lport=1143#011rport=47222#011resp=<hidden> Nov 15 12:43:53 proxy1 dovecot: auth: Debug: sql(adi2@0aditest.local,::1,<AorrLqp6drgAAAAAAAAAAAAAAAAAAAAB>): cache miss Nov 15 12:43:53 proxy1 dovecot: auth-worker(7533): Debug: Loading modules from directory: /usr/lib64/dovecot/auth Nov 15 12:43:53 proxy1 dovecot: auth-worker(7533): Debug: Module loaded: /usr/lib64/dovecot/auth/lib20_auth_var_expand_crypt.so Nov 15 12:43:53 proxy1 dovecot: auth-worker(7533): Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_mysql.so Nov 15 12:43:53 proxy1 dovecot: auth-worker(7533): Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so Nov 15 12:43:53 proxy1 dovecot: auth-worker(7533): Debug: sql(adi2@0aditest.local,::1,<AorrLqp6drgAAAAAAAAAAAAAAAAAAAAB>): query: SELECT NULL AS password, 'Y' as nopassword, host, 'any-cert' as 'starttls', 'Y' AS proxy FROM mailbox WHERE email = 'adi2(a)0aditest.local' AND disabled_smtpauth=0 Nov 15 12:43:53 proxy1 dovecot: auth: Debug: client passdb out: OK#0111#011user=adi2@0aditest.local#011host=192.168.123.24#011starttls=any-cert#011proxy#011pass=<hidden> Nov 15 12:43:53 proxy1 dovecot: imap-login: Invalid certificate: [...] Nov 15 12:43:53 proxy1 dovecot: imap-login: Invalid certificate: [...] Nov 15 12:43:53 proxy1 dovecot: imap-login: Invalid certificate: [...] Nov 15 12:43:53 proxy1 dovecot: imap-login: Invalid certificate: [...] Nov 15 12:43:53 proxy1 dovecot: imap-login: Invalid certificate: [...] Nov 15 12:43:53 proxy1 dovecot: imap-login: proxy(adi2(a)0aditest.local): started proxying to 192.168.123.24:143: user=<adi2(a)0aditest.local>, method=PLAIN, rip=::1, lip=::1, secured, session=<AorrLqp6drgAAAAAAAAAAAAAAAAAAAAB> Looks like user_query isn't executed, why?

Hi, in my imap_logout_format I register %{deleted} %{expunged} %{trashed} but now I saw that is available also %{autoexpunged}. Is necessary to add also %{autoexpunged} in logout format to have the count of all deleted email via IMAP?

execute sieve command - fails to notice script has exited
by Lionel Elie Mamane 13 Nov '18

13 Nov '18

Hi, Running dovecot 2.2.27 (c0f36b0) on Debian GNU/Linux stable (version 9.6), I'm trying to use the execute command in a sieve script, with direct execution (not service socket). The script is executed, and returns (the process exits), but the dovecot-lda process seems to not notice, and thinks the script did not terminate. After sieve_execute_exec_timeout has passed, it sends a TERM, a bit later a KILL and then logs a failure. The "ps -Af f" looks like: S 0:00 \_ /usr/sbin/exim4 -Mc 1gMazS-0007IV-RB S 0:00 \_ /usr/lib/dovecot/dovecot-lda -f master(a)blitz.conuropsis.org Z 0:00 | \_ [foofilter] <defunct> S 0:00 \_ /usr/sbin/exim4 -Mc 1gMazS-0007IV-RB The dovecot debug log looks like: lda(user): Debug: Loading modules from directory: /usr/lib/dovecot/modules lda(user): Debug: Module loaded: /usr/lib/dovecot/modules/lib90_sieve_plugin.so lda(user): Debug: Effective uid=1000, gid=1000, home=/home/user lda(user): Debug: maildir++: root=/home/user/Maildir, index=, indexpvt=, control=, inbox=/home/user/Maildir, alt= lda(user): Debug: userdb lookup skipped, username taken from USER environment lda(user): Debug: none: root=, index=, indexpvt=, control=, inbox=, alt= lda(user): Debug: Destination address: user(a)blitz.conuropsis.org (source: user@hostname) lda(user): Debug: sieve: Pigeonhole version 0.4.16 (fed8554) initializing lda(user): Debug: sieve: include: sieve_global is not set; it is currently not possible to include `:global' scripts. lda(user): Debug: sieve: Sieve imapsieve plugin for Pigeonhole version 0.4.16 (fed8554) loaded lda(user): Debug: sieve: Sieve Extprograms plugin for Pigeonhole version 0.4.16 (fed8554) loaded lda(user): Debug: sieve: file storage: Using active Sieve script path: /data/home/user/.dovecot.sieve lda(user): Debug: sieve: file storage: Using script storage path: /home/user/sieve lda(user): Debug: sieve: file storage: Relative path to sieve storage in active link: sieve/ lda(user): Debug: sieve: file storage: Using Sieve script path: /data/home/user/.dovecot.sieve lda(user): Debug: sieve: file script: Opened script `test-foofilter' from `/data/home/user/.dovecot.sieve' lda(user): Debug: sieve: Using the following location for user's Sieve script: /data/home/user/.dovecot.sieve lda(user): Debug: Mailbox stdin: Opened mail UID=1 because: header Message-ID (Cache file is unusable) lda(user): Debug: sieve: Opening script 1 of 1 from `/data/home/user/.dovecot.sieve' lda(user): Debug: sieve: Loading script /data/home/user/.dovecot.sieve lda(user): Debug: sieve: Script binary /data/home/user/.dovecot.svbin successfully loaded lda(user): Debug: sieve: binary save: not saving binary /data/home/user/.dovecot.svbin, because it is already stored lda(user): Debug: sieve: Executing script from `/data/home/user/.dovecot.svbin' lda(user): Debug: sieve: action execute: running program: foofilter lda(user): Debug: Mailbox stdin: Opened mail UID=1 because: mail stream lda(user): Debug: waiting for program `/usr/local/lib/dovecot/sieve-execute/foofilter' to finish after 0 msecs lda(user): Debug: program `/usr/local/lib/dovecot/sieve-execute/foofilter'(24669) execution timed out after 2000 milliseconds: sending TERM signal lda(user): Debug: program `/usr/local/lib/dovecot/sieve-execute/foofilter' (24669) did not die after 5000 milliseconds: sending KILL signal and an strace on the dovecot-lda process shows it is in an "epoll_wait(9 ....".

Proxy + 2x static passdb not working as expected
by Michael Goth 13 Nov '18

13 Nov '18

Hi all, I'm trying to setup a Dovecot proxy that authenticates the user against two backend servers. If login server1 fails, server2 should be tried. The problem: Only the first server seems to be tried, even if the login fails. Config snippet: protocol imap { passdb { driver = static args = proxy=y nopassword=y host=oldserver1.example.com port=993 ssl=y } passdb { driver = static args = proxy=y nopassword=y host=oldserver2.example.com port=993 ssl=y } } With this config, only accounts on oldserver1.example.com can login. If I reverse the two passdb entries, only accounts on oldserver2.example.com can login. I've done the same with SQL passdb first + static passdb second. That worked as expected. Not sure what I'm doing wrong here. Attached is the output of doveconf -n Thanks Michael Mit freundlichen Grüßen -- Michael Goth .webflow GmbH Geschäftsführer: Andreas Schrei Wasserburger Straße 4 D - 83352 Altenmarkt a. d.

dsync / doveadm sync problem
by admin＠awib.it 13 Nov '18

13 Nov '18

Hi, I had an old dovecot server with a working backup script. Basic concept was: - to dsync to a temp folder - using tar to preserve datetime - piping this 7z to benefit from my 16 core cpu - piping this through openssl to encrypt Over time the size of all my mail grew from 3GB to about 70GB. I used to keep the last 14 backups, but this uses a lot of space. I now want to dsync my Maildir onto my NAS via NFS and use the backup tool provided by Synology to have incremental compressed backup. However I cannot get dsync to run. root@mail:/mnt/backup_mail# dsync -f -u USER@DOMAIN backup maildir:/mnt/backup_mail/MAILSERVER_FQDN/DOMAIN/USER/mail dsync(USER@DOMAIN): Error: User initialization failed: Namespace '': stat(/mnt/backup_mail/MAILSERVER_FQDN/DOMAIN/USER/mail) failed: Permission denied (euid=1001(vmail) egid=1001(vmail) missing +x perm: /mnt/backup_mail, UNIX perms appear ok (ACL/MAC wrong?)) root@mail:/mnt/backup_mail# dsync -u USER@DOMAIN backup maildir:/mnt/backup_mail/MAILSERVER_FQDN/DOMAIN/USER/mail dsync(USER@DOMAIN): Error: User initialization failed: Namespace '': stat(/mnt/backup_mail/MAILSERVER_FQDN/DOMAIN/USER/mail) failed: Permission denied (euid=1001(vmail) egid=1001(vmail) missing +x perm: /mnt/backup_mail, dir owner missing perms) ——— Error message changed after removing „-f“. I then applied the folder permissions (chmod +x backup_mail/) and I get a different error: root@mail:/mnt/backup_mail# dsync -f -u USER@DOMAIN backup maildir:/mnt/backup_mail/MAILSERVER_FQDN/DOMAIN/USER/mail dsync(USER@DOMAIN): Error: User initialization failed: namespace configuration error: All list=yes namespaces must use the same separator I found something about the namespace issue, but did not quite understand I guess. (separators seem to differ) From doveconf -n: [...] namespace { list = children location = maildir:/var/vmail/mailboxes/%%d/%%n/Maildir:INDEXPVT=~/Maildir/shared/%%u prefix = shared/%%u/ separator = / subscriptions = yes type = shared } namespace inbox { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Spam { auto = subscribe autoexpunge = 30 days special_use = \Junk } mailbox Trash { auto = subscribe autoexpunge = 183 days special_use = \Trash } prefix = } […] ——— However I only set up the namespace for inbox. root@mail:/mnt/backup_mail# doveconf namespace gives namespace { disabled = no hidden = no ignore_on_failure = no inbox = no list = children location = maildir:/var/vmail/mailboxes/%%d/%%n/Maildir:INDEXPVT=~/Maildir/shared/%%u order = 0 prefix = shared/%%u/ separator = / subscriptions = yes type = shared } namespace inbox { disabled = no hidden = no ignore_on_failure = no inbox = yes list = yes location = mailbox Drafts { auto = subscribe autoexpunge = 0 autoexpunge_max_mails = 0 comment = driver = special_use = \Drafts } mailbox Sent { auto = subscribe autoexpunge = 0 autoexpunge_max_mails = 0 comment = driver = special_use = \Sent } mailbox Spam { auto = subscribe autoexpunge = 60 days autoexpunge_max_mails = 0 comment = driver = special_use = \Junk } mailbox Trash { auto = subscribe autoexpunge = 60 days autoexpunge_max_mails = 0 comment = driver = special_use = \Trash } order = 0 prefix = separator = subscriptions = yes type = private } I guess here we see the config including defaults. Well… I think I only need the inbox namespace either way, so I tried: root@mail:/mnt/backup_mail# dsync -f -u USER@DOMAIN backup maildir:/mnt/backup_mail/MAILSERVER_FQDN/DOMAIN/USER/mail/ -n inbox dsync-local(USER@DOMAIN): Error: read(remote) failed: EOF (version not received) doveadm(USER@DOMAIN): Fatal: execvp(maildir:/mnt/backup_mail/MAILSERVER_FQDN/DOMAIN/USER/mail/) failed: No such file or directory dsync-local(USER@DOMAIN): Error: Remote command process isn't dying, killing it dsync-local(USER@DOMAIN): Error: kill(15306, SIGKILL) failed: Operation not permitted The folder (mnt/backup_mail/MAILSERVER_FQDN/DOMAIN/USER/mail) however does exist. Can anybody tell me if there is something I miss? Thanks in advance! -M

I lost the whole maildir from my server fro 3 users. They all have iPhones with all the messages safely stored on the Apple Mail app on their phone. There is no way to export them/move them. Is there a way to get Dovecot to just download all the messages and folder structure from the client and restore it on the server? Your help is very very much appreciated. Thanks, ttyllc

Seen-Flag and Virtual
by Dieter Knopf 12 Nov '18

12 Nov '18

Hello, We have a very large folder structure (in a public namespace) on our Dovecot server and would now like to create a virtual folder containing all mails of the publick namespace. This worked quite well with dovecot-virtual, but the read status (\seen) is not preserved. i.e. when I read a mail inside the virtual folder, the read status does not affect the original mail. Dovecut was configured with per-user \seen-flag. Is it possible to synchronize the \seen-flag somehow? Thanks Dieter

moving only new mails from one server to another
by Nicolas 12 Nov '18

12 Nov '18

Hello, I think it is not really the right place to post about that, but lot of dovecot experts there ;) Basically, I have a server with dovecot 2.2.9 that has new (unread) mails (because of a bad DNS config at a migration time). Is there an easy way to move only these unread mails to a another server ? (no perms trouble here : all vmail:vmail) Though to iterate through all /var/vmail/*/*/Maildir/new and scp/rsync them. Would that work ? Thanks in advance for your time. Nicolas

Hi, is it, somehow, possible to distinguish between multiple simultaneous logins in MailLog plugin? For example, which login deleted which message. Is that p[lugin able to log e.g. session ID? azur

Dovecot mail-crypt plugin
by Anushka Uditha Bandara 07 Nov '18

07 Nov '18

I configured an email solution using dovecot and postfix and it is working fine. Now I am working for mail encryption. Is it enough to set below configurations on dovecot for mail encryption. Because dovecot wiki is little bit confusing to me. "mail_plugins = $mail_plugins mail_crypt mail_attribute_dict = file:%h/Maildir/dovecot-attributes plugin { mail_crypt_curve = <some curve you like> mail_crypt_save_version = 2 }" I am stuck in here. Thank you in advance, Anushka Bandara

LMTP with many aliases and replication
by Sean Greenslade 07 Nov '18

07 Nov '18

Hi, all. I'm currently in the process of rethinking / tinkering with my personal mail server. I've hit a few stumbling blocks that make me think I may be approaching this problem from the wrong angle. I have a large number of email addresses across several domains that all alias to the same inbox. In my current setup, postfix handles the aliases and dumps them all into a single "receiving" maildir, which gets processed by a custom python script to sort into one of several destination maildirs handled by dovecot. In evaluating this system, I'd like to move to using sieve for this sorting step, so (according to the docs) I need to use LMTP. This is my first stumble. Since I use so many aliases, my IMAP login username is not my email address. In fact, I have several IMAP usernames with different passwords pointing to the same maildir so that my phone can use a different password than my PC. The dovecot documentation was not very clear on how to make LMTP use a different userdb. I eventually found through some trial and error and some hints from other list threads that I could wrap a second userdb {} section with a protocol lmtp {} section, which seems to do the trick. I'd like to edit the wiki to include this helpful tidbit, but I find it odd that this isn't mentioned anywhere in the documentation for LMTP. Is it actually an intended feature? My second stumble is with the replicator plugin. I'd like to run two identical dovecot servers that replicate their mailboxes across each other. Since there are a large number of alias "accounts" that all feed into one IMAP account, the logical place to put the replication would be the IMAP account. But the way the replicator plugin seems to work, the trigger for synchronous replication on mail receipt fires on the LMTP "account" that received that particular message. Is there any way within dovecot to specify a different replication account to be triggered for sync? Like a userdb extra field or something? I'm trying to avoid needing external scripts if at all possible. I'm interested to hear people's thought / suggestions, especially if anyone has a better way of architecting this system. In case it's relevant, I'm running Arch Linux / Dovecot 2.3.3. Thanks, --Sean

Re: dovecot: imap Error: read : Broken pipe

I forgot to mention that if I transfer the mail to my Gmail or Outlook address I can download the attachments without any problem. More over I've completely removed the firewall server from the equation, I plugged the adsl line directly into the mail server and the problem is still there, so my guess is that the firewall isn't the problem here.

dovecot: imap Error: read : Broken pipe

Hi everyone, I'm trying to find a solution for this bug who appears 2 months ago : dovecot: imap(%USER%): Error: read(<binary stream of mailbox INBOX UID (%d)>) failed: Broken pipe (FETCH BINARY[2] for mailbox INBOX UID (%d) Where %USER% is the unix user and %d the UID of the mailbox. This error appears each time a user tries to download an attachment from one of his emails. Whether with RoundCube or Thunderbird via VPN or not. I thought that it was related to my firewall but no. Furthermore the problem isn't present when users are at the office. Upload speed from our ADSL connection is pretty slow about 1mpbs, I thought maybe it was related but it was working fine since 2 years. So I'm really short of ideas. Anyone could help me please ?

imap authentication - shadow vs mysql
by Konra Wawryn 05 Nov '18

05 Nov '18

Hi, I`m looking for some opinions about authentication process for the systems with more than 1000 E-mail accounts. Maybe some one could advise me what is the best authentication method. At the moment I`m storing all passwords in my /etc/passwd. My IMAP server is growing and I`m planning to build new host, my question is: what is the best authentication model for IMAP server ? Do I need to store all user/passwords in mysql or maybe in LDAP ? I`m searching for some solution which will help me to scale my system in the future. Maybe some one could advice me ? Greetings Konrad
