backup v rsync
by Jeff Abrahamson 27 May '21

27 May '21

I've been migrating from a dovecot 2.2.22 instance to a dovecot 2.3.7.2 instance. (Said differently, from an ubuntu 16.04 host to a 20.04 host.) It's a tiny site: only a handful of users actually had to migrate, most either died on the old one or were born on the new one. The main user in need of migration was me. After fiddling with dsync and not getting it working, I threw in the towel. This is a migration I had to do once for precisely one user. I had been using the old host exclusively, so it was easy to shut down both dovecot instances the time it took me to rsync my data from one to the other. Now that seems to work, almost. Mail is being delivered to my inbox, anyway. Most other folders are looking inaccessible to my mail client (thunderbird, for this test). The main difference between the two servers, aside from the above, is a switch from mail_location = maildir:~/Maildir to mail_home = /var/mail/vmail/%d/%n mail_location = maildir:/var/mail/vmail/%d/%n/mail:LAYOUT=fs mail_privileged_group = mail I corrected permissions and ownership when I copied the data. Now I think the problem is that LAYOUT=fs means that I should have a slightly different folder hierarchy now. The question is how best to fix this. I have things like this .Archives.2020 .Archives.2020/new .Archives.2020/tmp .Archives.2020/cur when I think I should have things like this Archives Archives/2021 Archives/2021/new Archives/2021/tmp Archives/2021/cur And, again, this is one-off, so a manual fix seems most appropriate. I'm quite tempted simply to shut down the dovecot instance for a minute at a quiet moment (mail retries...) and rename directories as indicated above. I only have to rename five directories. Having gotten myself in a bit of a muddle on this, I thought perhaps a reality check that I'm not about to make it worse would be appropriate. Many thanks. -- Jeff Abrahamson +33 6 24 40 01 57 +44 7920 594 255 https://www.p27.eu/jeff/ https://www.mobilitains.fr/

API command for ACL Delete
by Rhodri Jones 27 May '21

27 May '21

I asked previously for info about the API options for doveadm acl delete but I think my question was misunderstood. I want to know the command I would use (with curl for instance) that corresponds with: doveadm acl delete -u <targetmailbox> INBOX user=<targetuser> Using the python client for doveadm http API I can see the valid parameters but I don't seem to be able to get the correct syntax. (doveadm) aclDelete ? invalid parameter: ? valid parameters for aclDelete: - userFile (string) - allUsers (boolean) - mailbox (string) - user (string) - socketPath (string) - id (string) --

Problem with per-user \Seen flag on public folder
by Bartek Szady 26 May '21

26 May '21

Hello I have noticed that when per-user \Seen flag is configured dovecot do not respond properly to 'store' command. eg.: =============== 42 uid store 6 +Flags (\Seen) 42 OK Store completed (0.001 + 0.000 secs). 43 IDLE + idling DONE 43 OK Idle completed (3.204 + 3.203 + 3.203 secs). =============== Thunderbird is confused by this and read emails turns into unread after a while. When global flag is stored dovecot responds as it should, I think: =============== 32 uid store 3 -Flags (\Flagged) * 2 FETCH (UID 3 FLAGS ()) 32 OK Store completed (0.002 + 0.000 + 0.001 secs). 33 IDLE + idling DONE 33 OK Idle completed (5.362 + 5.362 + 5.361 secs). =============== When per-user \Seen flag is not configured: =============== 25 uid store 6 +Flags (\Seen) * 4 FETCH (UID 6 FLAGS (\Seen)) 25 OK Store completed (0.002 + 0.000 + 0.001 secs). 26 IDLE + idling * OK Still here DONE 26 OK Idle completed (65.076 + 65.076 + 65.076 secs). =============== # doveconf -n # 2.3.14 (cee3cbc0d): dovecot-int.conf # OS: Linux 5.1.16 x86_64 # Hostname: #hidden auth_mechanisms = plain login base_dir = /var/run/dovecot-int default_internal_group = dovecot1 default_internal_user = dovecot1 default_login_user = dovenull1 disable_plaintext_auth = no login_log_format = int %$: %s mail_debug = yes mail_location = maildir:~/Mail/Maildir mail_log_prefix = "int-%s(%u)<%{pid}><%{session}>: " namespace { inbox = yes location = prefix = separator = / type = private } passdb { args = scheme=MD5-CRYPT /etc/dovecot/passwd-int driver = passwd-file } passdb { args = scheme=MD5-CRYPT /etc/dovecot/virtual-int driver = passwd-file } passdb { driver = pam } plugin { acl = vfile } protocols = pop3 imap service auth { user = root } service imap-login { group = dovenull1 inet_listener imap { address = <ips> } user = dovecot1 } service pop3-login { group = dovenull1 inet_listener pop3 { address = <ips> } } service stats { unix_listener stats-writer { mode = 0660 user = pubmail } } ssl_cert = </var/lib/openssl/certs/imap-int.crt ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { args = /etc/dovecot/virtual-int driver = passwd-file } userdb { driver = passwd } protocol imap { mail_plugins = acl imap_acl namespace { location = maildir:/srv/mail/public:LAYOUT=fs:INDEXPVT=~/Mail/public prefix = publiczne/ separator = / subscriptions = no type = public } ssl = yes } Bartek

What am I doing wrong?
by Ron Garret 26 May '21

26 May '21

I’m trying to run an imapsieve script when a user sends a message (this is part of a spam filter and I want to use outgoing messages to train the filter on good content). This is my config: plugin { sieve_plugins = sieve_imapsieve sieve_extprograms sieve = file:/var/mail/sieve/incoming.sieve # From elsewhere to Junk imapsieve_mailbox1_name = Junk imapsieve_mailbox1_causes = COPY imapsieve_mailbox1_before = file:/var/mail/sieve/spam.sieve # From Junk to elsewhere imapsieve_mailbox2_name = * imapsieve_mailbox2_from = Junk imapsieve_mailbox2_causes = COPY imapsieve_mailbox2_before = file:/var/mail/sieve/ham.sieve # Sent imapsieve_mailbox3_name = 'Sent Messages' imapsieve_mailbox3_causes = APPEND imapsieve_mailbox3_before = file:/var/mail/sieve/sent.sieve sieve_pipe_bin_dir = /var/mail/sieve sieve_global_extensions = +vnd.dovecot.pipe +vnd.dovecot.environment } The first two scripts (for training spam and ham respectively) both work. Once upon a time I had the third one working as well, but apparently I changed something that made it break and I have no idea what that could be. (Yes, I need to get my code into revision control. I’ve already beaten myself up over that more than once.) The problem appears to be in the config, not the sieve script, because the script is never compiled into a .svbin while the other scripts in the same directory are compiled. But just for the record, this is the sieve script: > ➔ cat /var/mail/sieve/sent.sieve > require ["vnd.dovecot.pipe", "copy", "imapsieve", "environment", "variables"]; > > if environment :matches "imap.user" "*" { > set "username" "${1}"; > } > > pipe :copy "train.py" [ "sent", "${username}" ]; Does anyone here see the problem that I’m missing? Thanks, rg

sqlite + IMAP Authentication issues - user unknown

Panic: file ostream-zlib.c
by Bouke J. Henstra | ICT Diensten 24 May '21

24 May '21

Hello, At the moment I am investigating an issue (probably) related to Dovecot /zlib. I am hoping someone is willing to help. Thanks. #Background information Every time a certain user checked her e-mail the following errors would appear in "/var/log/mail.err" (please find the lines below). I am using zlib (please find the details in the configuration below). I did include the Dovecot version, OS details, CPU details and file system details in this message. I did migrate the whole mail domain to Microsoft 365 (as the user has an active subscription and had to move on - for me this was the fastest method to help the user in this case). The mailbox still exists on the server. I suspect there's file corruption somewhere? I am routing mail from the domain to xxxxx-xx.mail.protection.outlook.com (just to be sure that the user doesn't miss anything - mx records have been updated). I did notice that the user had issues with receiving mail. Outlook would keep trying to fetch mail and was hard to close (user had to kill Outlook through the task manager - after migrating to Microsoft 365 this problem is resolved too). I would like to find out what causes/caused this problem. I would like to understand the problem and would like to try to avoid future problems. I did run "dovecot-sysreport" but I did notice the data is not anonymized. I can anonymize the details and submit those if required. #Dovcecot version root@s1:/# dovecot --version 2.3.4.1 (f79e8e7e4) #Operating system root@s1:/# uname -a Linux s1 4.19.0-16-amd64 #1 SMP Debian 4.19.181-1 (2021-03-19) x86_64 GNU/Linux root@s1:/# cat /etc/debian_version 10.9 #CPU Architecture root@s1:/# lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian #File System ext4 errors=continue,usrjquota=quota.user,grpjquota=quota.group,jqfmt=vfsv0 0 1 #Errors May 17 22:37:11 s1 dovecot: imap(xxxx(a)xxxxx.xx)<18570><MxyEjIzCs8pSoYVo>: Panic: file ostream-zlib.c: line 37 (o_stream_zlib_close): assertion failed: (zstream->ostream.finished || zstream->ostream.ostream.stream_errno != 0 || zstream->ostream.error_handling_disabled) May 17 22:37:11 s1 dovecot: imap(xxxx(a)xxxxx.xx)<18570><MxyEjIzCs8pSoYVo>: Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0xdb73b) [0x7f45c109973b] -> /usr/lib/dovecot/libdovecot.so.0(+0xdb7d1) [0x7f45c10997d1] -> /usr/lib/dovecot/libdovecot.so.0(+0x4a199) [0x7f45c1008199] -> /usr/lib/dovecot/modules/lib20_zlib_plugin.so(+0x3c6f) [0x7f45c0dc3c6f] -> /usr/lib/dovecot/libdovecot.so.0(+0xffd5e) [0x7f45c10bdd5e] -> /usr/lib/dovecot/libdovecot.so.0(o_stream_destroy+0x16) [0x7f45c10bdd86] -> /usr/lib/dovecot/libdovecot-storage.so.0(maildir_save_finish+0x18d) [0x7f45c11d046d] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_save_cancel+0x4d) [0x7f45c11a867d] -> dovecot/imap(+0x10f36) [0x5606b3187f36] -> dovecot/imap(+0x10ff3) [0x5606b3187ff3] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x6f) [0x7f45c10afbef] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x136) [0x7f45c10b11e6] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x4c) [0x7f45c10afc8c] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x40) [0x7f45c10afdf0] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f45c1030123] -> dovecot/imap(main+0x325) [0x5606b3187bf5] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xeb) [0x7f45c0e1309b] -> dovecot/imap(_start+0x2a) [0x5606b3187d8a] May 17 22:37:11 s1 dovecot: imap(xxxx(a)xxxxx.xx)<18570><MxyEjIzCs8pSoYVo>: Fatal: master: service(imap): child 18570 killed with signal 6 (core dumps disabled -
