04 Dec '18

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

Hi, First of all, what are you using to send this e-mail? I am receiving this as an attachment. (Anyone else seeing this? More mails from different senders seem to be affected.)

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. Especially in the area of technical mailing lists I see no reason to cater to dumb MUA software. > Email should be intitive If by "intuitive" you mean "used without engaging one's brain", I have to disagree.

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

Hi! It seems we accidentically had a high amount of subscribers temporarily disabled due to DMARC on some sender's host. We have now taken actions to prevent this in the future and all temporarily disabled members have been restored. Aki

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. Server is freshly set up Ubuntu 18.04.1, latest patchlevel with packages mostly from Ubuntu sources, except rspamd, but this was added as ppa if my remembering is correct. This is what I get on syslog, whilst *.* is being put at /var/log/allmessages. ######################################### Nov 25 23:30:50 myserver dovecot: imap(info(a)mydomain.tld): Debug: INBOX/Junk: Mailbox opened because: UID move Nov 25 23:30:50 myserver dovecot: imap(info(a)mydomain.tld): Debug: imapsieve: mailbox INBOX/Junk: MOVE event Nov 25 23:30:50 myserver dovecot: imap(info(a)mydomain.tld): Debug: sieve: Pigeonhole version 0.4.21 (92477967) initializing Nov 25 23:30:50 myserver dovecot: imap(info(a)mydomain.tld): Debug: sieve: Sieve imapsieve plugin for Pigeonhole version 0.4.21 (92477967) loaded Nov 25 23:30:50 myserver dovecot: imap(info(a)mydomain.tld): Debug: sieve: Sieve Extprograms plugin for Pigeonhole version 0.4.21 (92477967) loaded Nov 25 23:30:50 myserver dovecot: imap(info(a)mydomain.tld): Debug: imapsieve: Static mailbox rule [1]: mailbox=`Junk' from=`*' causes=(COPY) => before=`file:/etc/dovecot/sieve/report-spam.sieve' after=(none) Nov 25 23:30:50 myserver dovecot: imap(info(a)mydomain.tld): Debug: imapsieve: Static mailbox rule [2]: mailbox=`*' from=`Junk' causes=(COPY) => before=`file:/etc/dovecot/sieve/report-ham.sieve' after=(none) ######################################### So as far as I can interpret there is absolutely no script called when I move a mail from inbox to junk folder in Thunderbird.

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)

Installing on Mojave, with Homebrew and mysql

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.
