Dovecot Submission Proxy Auth
by Paul Hecker 12 Jan '19

12 Jan '19

Hi, Dovecot 2.3.1 (8e2f634). Could not get Dovecot to forward the (plain) authentication to the SMTP server using submission. Reason why I need it is sender spoofing (do not want my employees to send messages in behalf of me). In exim I can disable sender spoofing with the authenticated user. When sending through dovecot, exim either does not accept the email (need auth) or relay every sender address (because relaying from localhost). Am I missing a setting or do I need any additional field in the (MySQL) user_query/password_query to forward the password? You can find my config here: https://gist.github.com/lluuaapp/7daddf761131da47237b0f45e6bab5a8 Thanks, Paul

RE: Dovecot (doveadm, ssl, sync) - SSL error

Hello! dsync SSL still doesn't work for replication, so I've disabled it and tried to sync without. But I have a problem with temp directory. Is it possible to change path to temp folder? I don't want to set permissions but change temporary folder for replication.

outlook idiocy - IMAP folders with /
by Wojciech Puchar 20 Dec '18

20 Dec '18

user attempts to create folders with / dovecot naturally cannot create it so it returns error but outlook of course "create" it and keep data in local store only. data is lost when you remove local store .pst file. The question is - can dovecot be configured so it will automatically replace slash in name with something else?

Sieve notify variables not working with body?
by Bambero 09 Dec '18

09 Dec '18

Hi, I want to send notification like this: if body :text :matches "*" { notify :importance "3" :message "[NOTIFY] ${1}" "mailto:test@example,com"; } The notification works but the variable ${1} seems to be empty. But in this case: if header :matches "Subject" "*" { notify :importance "3" :message "[NOTIFY] ${1}" "mailto:test@example,com"; } Everything works correct. Regards, Bambero

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! 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)
