FW: imapsieve rules not matching at all?
by dovecot＠steve.wattlink.net 20 Mar '21

20 Mar '21

Greetings! I feel like this has been beaten to death, but my searches on the web (and about 10 hours spent over the last two days) haven't revealed what's going on. Basically, it's the usual "I'd like to auto-learn spam/ham based on moves to/from a folder" problem. But in my debugging, I don't see any evidence that the static rules are matching, so the scripts aren't running, which makes me think I'm missing something obvious. Below I list doveconf -n output, and some log snippets. In my experiments, I've tried removing the report-spam.sieve and report-ham.sieve scripts, and absolutely nothing changed, which is why I think the rules aren't being tried. The requisite doveconf -n output: - - - -8< - - - - # 2.3.13 (89f716dc2): /usr/local/etc/dovecot/dovecot.conf # Pigeonhole version 0.5.13 (cdd19fe3) # OS: FreeBSD 12.2-RELEASE-p1 amd64 # Hostname: mhv3 lock_method = dotlock mail_attribute_dict = file:%h/Maildir/dovecot-attributes mail_debug = yes mail_location = maildir:~/Maildir mail_privileged_group = mail 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 vnd.dovecot.debug vnd.dovecot.environment imapsieve vnd.dovecot.imapsieve vnd.dovecot.pipe vnd.dovecot.execute 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 { driver = pam } plugin { imapsieve_mailbox1_before = file:/usr/local/etc/dovecot/sieve/report-spam.sieve imapsieve_mailbox1_causes = COPY APPEND imapsieve_mailbox1_name = Spam imapsieve_mailbox2_before = file:/usr/local/etc/dovecot/sieve/report-ham.sieve imapsieve_mailbox2_causes = COPY imapsieve_mailbox2_from = Spam imapsieve_mailbox2_name = * imapsieve_url = sieve://127.0.0.1:4190 sieve = file:~/sieve;active=~/.dovecot.sieve sieve_before = /usr/local/etc/dovecot/sieve/common.sieve sieve_default = /usr/local/etc/dovecot/sieve/default.sieve sieve_default_name = SystemDefault sieve_execute_bin_dir = /usr/local/etc/dovecot/sieve/bin sieve_extensions = +vnd.dovecot.pipe +vnd.dovecot.environment +vnd.dovecot.execute +vnd.dovecot.debug sieve_filter_bin_dir = /usr/local/etc/dovecot/sieve/bin sieve_global = /usr/local/etc/dovecot/sieve sieve_pipe_bin_dir = /usr/local/etc/dovecot/sieve/bin sieve_plugins = sieve_imapsieve sieve_extprograms sieve_trace_addresses = no sieve_trace_debug = yes sieve_trace_dir = /var/log/dovecot/trace sieve_trace_level = matching } protocols = imap lmtp sieve service imap-login { inet_listener imap { address = 127.0.0.1 } } service managesieve-login { inet_listener sieve { port = 4190 } } ssl_cert = </etc/ssl/services/dovecot.cert ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { driver = passwd } protocol lda { mail_plugins = " sieve" } protocol imap { imap_metadata = yes mail_max_userip_connections = 30 mail_plugins = " imap_sieve" } - - - ->8 - - - - I see that the static rule ought to have matched, but it didn't?

Some questions about code in lib-storage/index/maildir
by songliny 18 Mar '21

18 Mar '21

Hi, Recently, I have read some code in dovecot 2.3.13. And I have 2 questions about some lines of code in lib-storage/index/maildir Firstly, in the function, maildir_scan_dir, from lib-storage/index/maildir/maildir-sync.c around line 575 (https://github.com/dovecot/core/blob/6986a435e31dfe5bcd14985534b76b3c735f78…) I would like to know that after successfully stat the cur directory, does it assign the max value between st.st_mtime and start_time intensionally to new_check_time? Or maybe should it assign the value to the cur_check_time. if (stat(ctx->cur_dir, &st) == 0) { ctx->mbox->maildir_hdr.new_check_time = I_MAX(st.st_mtime, start_time); ctx->mbox->maildir_hdr.cur_mtime = st.st_mtime; ctx->mbox->maildir_hdr.cur_mtime_nsecs = ST_MTIME_NSEC(st); } Secondly, in the function, maildir_uidlist_sync_next_uid, from lib-storage/index/maildir/maildir-uidlist.c (https://github.com/dovecot/core/blob/6986a435e31dfe5bcd14985534b76b3c735f78… rc/lib-storage/index/maildir/maildir-uidlist.c#L1760) Is it ok to remove MAILDIR_UIDLIST_REC_FLAG_NEW_DIR flag from the record for the record that is not found in ctx->files just like the behavior (https://github.com/dovecot/core/blob/6986a435e31dfe5bcd14985534b76b3c735f78… the function, maildir_uidlist_sync_next_partial (https://github.com/dovecot/core/blob/6986a435e31dfe5bcd14985534b76b3c735f78…) from the same file? I think when it gets to the function, maildir_uidlist_sync_next_uid, the mail file have already been moved to cur directory. And maybe it is ok to remove MAILDIR_UIDLIST_REC_FLAG_NEW_DIR flag from the record. That is, is it ok to add this line rec->flags &= ENUM_NEGATE(MAILDIR_UIDLIST_REC_FLAG_NEW_DIR); just before rec->flags = (rec->flags | flags) & ENUM_NEGATE(MAILDIR_UIDLIST_REC_FLAG_NONSYNCED); in maildir_uidlist_sync_next_uid? Thank you in advance to he lp me get more understanding to these questions, Sony

dovecot director and keepalived
by Steven Varco 18 Mar '21

18 Mar '21

Hi All I’m trying to establish a dovecot HA setup with two loadbalancers, running keepalived for sharing a virtual public IP. On the same machines I’m running a dovecot director which proxies the requests to two underlying mail servers (on seperate machines). Now I’m hitting the issue with the way director determines his „Self IP“ by trying to bind to all configured director_servers IPs, taking the first one possible. However this approach only works, when the sysctl setting is: net.ipv4.ip_nonlocal_bind=0 On the other side keepalived needs net.ipv4.ip_nonlocal_bind=1 in order to bind the VIP. The last topic on that is dating back to 2016 (https://dovecot.org/pipermail/dovecot/2016-August/105191.html) with references to 2012 (https://www.dovecot.org/list/dovecot/2012-November/087033.html) and no solution posted so far. After five more years :D, I’m asking myself if we finally have a solution for that, or if my approach of achieving clustered director servers is potentially wrong? Other possible solutions I could think about: - Configure each director as „independent“ by setting only one IP in director_servers. => With this aporach you would loose the user to mailserver mapping, although only in a a case of a failover on the loadbalancer, which might can be neglected (or are there any other fallbacks?) - Only have director running on the currently active loadblancer node and stopped on the passive loadblancer node (would possibly have the same effects as above). - Putting director on seperated intermediate machines and proxing the requests through haproxy on the keepalived servers (keepalived -> haproxy -> director -> IMAP => Besides the disadvantage of having another bunch of servers in the chain, also some special configuration on the directory servers might be neccessary to assure director works neatly with haproxy. So 2021, what is the „correct“ (best practive) way of having a reduntant HA setup for dovecot? This means a MUA connects to one public IP and gets connected to (preferably the same) IMAP Server, no matter which machine in the whole chain might be down? PS: Using just multiple A records on the mail domain name (round-robin), while working perfectly for SMTP is not accepatbl for IMAP IMHO, as in case of a failure every second request from the client (MUA) would fail and most MUAs are not automatially reconnecting again in that case. thanks, Steven -- https://steven.varco.ch/

best practice purging only moved messages

If I move a message from the 'inbox' namespace to my 'archive' namespace. The message is expunged at the 'inbox' namespace and added to the 'archive' namespace. What is the best way to only purge messages that have been moved. (I do not want to purge emails that have been deleted yet)

How can I migrate mailboxes after changing hierarchy separator?
by Popkornium18 17 Mar '21

17 Mar '21

Hi, I had a common problem (folders can't contain dots) and the obvious solution seems to be changing the hierarchy separator and using the listescape plugin. My question is: Do I need to take any extra steps after changing the separator to migrate my existing mailboxes? If so, which? I tried just simply renaming the folders and doing a `doveadm force-resync` but that did not work as intended. Afterwards I wasn't able to subscribe to any of my folders, so I guess that isn't the way to go. Kind regards Simon

feature request: prevent linking of email
by Marc 17 Mar '21

17 Mar '21

What I have been doing wrong with testing expunged emails, is working with linked copies of emails. Although thunderbird copies the message, it looks like the message is NOT copied but linked. If I drag 3 emails from my desktop to a folder INBOX/test4 and copy 1 message from INBOX to INBOX/test4. I have 4 messages in this folder. I now shift+del this folder. The expunged messages listing gives me the expected 3 messages doveadm -o mail_location=mdbox_deleted:/home/popusers/testtest/mdbox:INDEX=/home/popindex/testtest/index mailbox status -u testtest 'messages vsize' '*' Sent messages=0 vsize=0 Drafts messages=0 vsize=0 INBOX/test2 messages=0 vsize=0 Junk messages=0 vsize=0 Trash messages=0 vsize=0 test3 messages=0 vsize=0 test1 messages=0 vsize=0 RESTORED messages=0 vsize=0 INBOX messages=3 vsize=18079344 Lets recover these: doveadm -v import -u testtest 'mdbox_deleted:/home/popusers/testtest/mdbox:INDEX=/home/popindex/testtest/index' RESTORED ALL Now I have 3 messages back, as expected. From an end users perspective if you delete a folder with 4 emails, you want your restored backup to have 4 emails, not 3 because one is already somewhere else in your folder/mailbox structure. The reason for copying an email to a different folder is that it is important. You do not want to loose it, and you want to be able to find it there. It is wrong to assume that a user will notice that these emails are missing and should look for them elsewhere. Say you have folder for a court case, and you copy emails there relevant for the court case. How can you ever know after a restore that a few email are missing from the folder, and which ones. I think it is bad this email is currently 'lost'. I rather have an option in dovecot that disables this hidden 'deduplication' feature. I think this should be the default setting also. This current deduplication feature also is hazardous because if this one copy of the email gets corrupted on the storage, you have no copies left. That is exactly the opposite of what user wants to accomplish with creating a copy. Feature request: disable this automatic linking of emails between mailboxes. Feature request: set this as a default.

I am trying to have mail from several shared mailboxes show up in a user's INBOX if they are unread or younger than 24h, using the filter "or (unseen) (all younger 86400)".

how to reclaim disk space mdbox
by Marc 15 Mar '21

15 Mar '21

When I delete messages in the archive namespace they are copied to the deleted items folder in the inbox namespace. This is 34MB increase is visible however I expected the archive to go down by 34MB. Is diskspace reclaimed automatically or do you need to issue an command? [@ sbin]# du -s -k /home/popusers/testtest /home/mail-archive/testtest 135472 /home/popusers/testtest 358824 /home/mail-archive/testtest [@ sbin]# du -s -k /home/popusers/testtest /home/mail-archive/testtest 169368 /home/popusers/testtest 358824 /home/mail-archive/testtest PS. I have mdbox_rotate_size = 4 M

Maybe it is nice to introduce some option to Doveadm-Purge that does not delete anything just logs what it wanted to delete sort of like rsync's -n option.

Virtual users @ virtual domains / better documentation?
by justina colmena ~biz 15 Mar '21

15 Mar '21

I have configured postfix so it will deliver mail to virtual mailboxes. For some reason, the mail is not delivered to the virtual mailboxes unless both $virtual_alias_domains and $virtual_alias_maps are left undefined: these directives are apparently for aliasing virtual users "@" virtual domains to "real" unix users on the local system. --%%== # ADDRESS REDIRECTION (VIRTUAL DOMAIN) # # The VIRTUAL_README document gives information about the many forms # of domain hosting that Postfix supports. virtual_mailbox_domains = domain1.example.org domain2.example.com virtual_transport = virtual #virtual_alias_domains = domain1.example.org domain2.example.com virtual_mailbox_base = /var/mail/vhosts virtual_mailbox_maps = hash:/etc/postfix/vmailbox virtual_minimum_uid = 100 virtual_uid_maps = static:5000 virtual_gid_maps = static:5000 #virtual_alias_maps = hash:/etc/postfix/virtual ==%-- If the $virtual_alias_maps directive invalidates virtual mailboxes, then "the usual" aliases (postmaster@, etc.) for the virtual domains would have to be listed in /etc/aliases along with the non-virtual aliases, but this does not work either, and generates a warning when "newaliases" is run. postalias: warning: /etc/aliases, line 99: name must be local So as far as I can tell, no aliasing at all is available for "virtual_mailbox_domains" in postfix I am still unsure how to authenticate the virtual users on postfix. PAM authentication works fine for non-virtual users. The following command gives two options for authentication: cyrus-sasl and dovecot-sasl. # postconf -a cyrus dovecot Postfix also works with cyrus-sasl if the passwords are set in "/etc/sasldb2" via the "saslpasswd2" command, but dovecot doesn't seem to work with cyrus-sasl, and has its own type of sasl authentication. I realize this is not a postfix list, so my real question here is, What do I need in order for dovecot to authenticate the virtual users and allow them to read their mail and obtain authorization to send mail via postfix on the same system?

auto scaling dovecot server on AWS

Hello There - I'm trying to setup dovecot server on AWS and would like to understand the approach on the email server sizing? The emails are expected to surge at times seasonally. How do I plan the email server sizing to handle such load? Does this support auto-scaling? Probably I'm missing the basics. Appreciate your help in giving some clarity.

09 Mar '21

Hi! We are pleased to release v2.3.14 of Dovecot. IMPORTANT NOTE: We have removed some components from the software, please review changelogs carefully prior upgrading. Please find source tarballs at https://dovecot.org/releases/2.3/dovecot-2.3.14.tar.gz https://dovecot.org/releases/2.3/dovecot-2.3.14.tar.gz.sig Binary packages in https://repo.dovecot.org/ Docker images in https://hub.docker.com/r/dovecot/dovecot Aki Tuomi Open-Xchange oy --- * Added new aliases for some variables. Usage of the old ones is possible, but discouraged. (These were partially added already to v2.3.13.) See https://doc.dovecot.org/configuration_manual/config_file/config_variables/ for more information. * Optimize imap/pop3/submission/managesieve proxies to use less CPU at the cost of extra memory usage. * Remove autocreate, expire, snarf and mail-filter plugins. * Remove cydir storage driver. * Remove XZ/LZMA write support. Read support will be removed in future release. * doveadm -D: Add timestamps to debug output even when LOG_STDERR_TIMESTAMP environment variable is not set. Timestamp format is taken from log_timestamp setting. * If BROKENCHAR or listescape plugin is used, the escaped folder names may be slightly different from before in some situations. This is unlikely to cause issues, although caching clients may redownload the folders. * imapc: It now enables BROKENCHAR=~ by default to escape remote folder names if necessary. This also means that if there are any '~' characters in the remote folder names, they will be visible as "~7e". * imapc: When using local index files folder names were escaped on filesystem a bit differently. This affects only if there are folder names that actually require escaping, which isn't so common. The old style folders will be automatically deleted from filesystem. * stats: Update exported metrics to be compliant with OpenMetrics standard. + doveadm: Add an optional '-p' parameter to metadata list command. If enabled, "/private", and "/shared" metadata prefixes will be prepended to the keys in the list output. + doveconf: Support environment variables in config files. See https://doc.dovecot.org/configuration_manual/config_file/config_file_syntax… for more details. + indexer-worker: Change indexer to disconnect from indexer-worker after each request. This allows service indexer-worker's service_count & idle_kill settings to work. These can be used to restart indexer-worker processes once in a while to reduce their memory usage. - auth: "nodelay" with various authentication mechanisms such as apop and digest-md5 crashed AUTH process if authentication failed. - auth: Auth lua script generating an error triggered an assertion failure: Panic: file db-lua.c: line 630 (auth_lua_call_password_verify): assertion failed: (lua_gettop(script->L) == 0). - configure: Fix libunwind detection to work on other than x86_64 systems. - doveadm-server: Process could crash if logging was done outside command handling. For example http-client could have done debug logging afterwards, resulting in either segfault or Panic: file http-client.c: line 642 (http_client_context_close): assertion failed: (cctx->clients_list == NULL). - dsync: Folder name escaping with BROKENCHAR didn't work completely correctly. This especially caused problems with dsync-migrations using imapc where some of the remote folder names may not have been accessible. - dsync: doveadm sync + imapc doesn't always sync all mails when doing an incremental sync (-1), which could lead to mail loss when it's used for migration. This happens only when GUIDs aren't used (i.e. imapc without imapc_features=guid-forced). - fts-tika: When tika server returns error, some mails cause Panic: file message-parser.c: line 802 (message_parser_deinit_from_parts): assertion failed: (ctx->nested_parts_count == 0 || i_stream_have_bytes_left(ctx->input)) - lib-imap: imapc parsing illegal BODYSTRUCTUREs with NILs could have resulted in crashes. This exposed that Dovecot was wrongly accepting atoms in "nstring" handling. Changed the IMAP parsing to be more strict about this now. - lib-index: If dovecot.index.cache has corrupted message size, fetching BODY/BODYSTRUCTURE may cause assert-crash: Panic: file index-mail.c: line 1140 (index_mail_parse_body_finish): assertion failed: (mail->data.parts != NULL). - lib-index: Minor error handling and race condition fixes related to rotating dovecot.index.log. These didn't usually cause problems, unless the log files were rotated rapidly. - lib-lua: Lua scripts using coroutines or lua libraries using coroutines (e.g., cqueues) panicked. - Message PREVIEW handled whitespace wrong so first space would get eaten from between words. - FTS and message PREVIEW (snippet) parsed HTML &entities case-sensitively. - lib-mail: When max nested MIME parts were reached, IMAP BODYSTRUCTURE was written in a way that may have caused confusion for IMAP clients and also Dovecot itself when parsing it. The truncated part is now written out using application/octet-stream MIME type. - lib-oauth2: HS512 and HS384 JWT token algorithms crash when you try to use them: Panic: file hmac.c: line 26 (hmac_init): assertion failed: (meth->context_size <= MAC_MAX_CONTEXT_SIZE). - event filters: NOT keyword did not have the correct associativity. NOT a AND b were getting parsed as NOT (a AND b) instead of (NOT a) AND b. - Ignore ECONNRESET when closing socket. This avoids logging useless errors on systems like FreeBSD. - event filters: event filter syntax error may lead to Panic: file event-filter.c: line 137 (event_filter_parse): assertion failed: (state.output == NULL) - lib: timeval_cmp_margin() was broken on 32-bit systems. This could potentially have caused HTTP timeouts to be handled incorrectly. - log: instance_name wasn't used as syslog ident by the log process. - master: After a service reached process_limit and client_limit, it could have taken up to 1 second to realize that more client connections became available. During this time client connections could have been unnecessarily rejected and a warning logged: Warning: service(...): process_limit (...) reached, client connections are being dropped - stats: Crash would occur when generating openmetrics data for metrics using aggregating functions. - stats: Event filters comparing against empty strings crash the stats process.

not getting internal errors logged
by Arkadiusz Miśkiewicz 08 Mar '21

08 Mar '21

Hello. dovecot 2.3.13, 2.3.14 web imap client when doing search is getting error induced by me by deleting lucene-indexes folder: UID SEARCH: Internal error occurred. Refer to server log for more information. [2021-03-08 15:08:01] (0.002 + 0.000 + 0.001 secs). but I'm not getting that internal error logged in syslog. Other information like from lmtp, imap logging in, out etc is logged just fine. In my configs log_path info_log_path debug_log_path are not set, so dovecot default syslog is used. Tested log_path = /tmp/file.txt, too but the effect was the same (regular logs logged there, internal errors not logged) stracing dovecot process I see error message only write()n once (to client) but nowhere else (in a strace visible way). Is anything else controlling internal errors logging? Can't find anything in docs. -- Arkadiusz Miśkiewicz, arekm / ( maven.pl | pld-linux.org )

Mailbox configuration questions
by justina colmena ~biz 08 Mar '21

08 Mar '21

I am having subtle problems with IMAP mailbox configuration on certain clients such as KMail and Thunderbird, whereas the previous setup was working on K9Mail (mobile) and Trojitá (desktop). I was using Maildir folders, which were mostly working before, but for some reason I had to create explicitly named namespaces for the flatfile (mbox) Inbox and the Maildir "Home" folders. I also specified an INDEX directory for the inboxes, which I made world-writable and sticky, because of permission problems creating subdirectories in it. KMail always seems to put sent mail into a local "sent-mail" folder, rather than the IMAP Sent folder associated with the sending account. (KMail and Thunderbird have a more POP-oriented architecture for the desktop, whereas Trojitá is exclusively IMAP.) Is there an easier better way to organize some of this stuff? Or how is it "usually" done?

About TLS variables
by Henry 04 Mar '21

Hello, I found the Variable %c only has TLS, Can it be using "TLSv1, TLSv1.1, TLSv1.2, TLSv1.3" instead of only TLS like as dovecot logging, this is really a most meaningful , thanks Variable %cLong name securedDescription “TLS” with established SSL/TLS connections, “TLS handshaking”, or “TLS [handshaking]: error text” if disconnecting due to TLS error. “secured” with localhost connections. Otherwise empty.

Why Last-login?
by ＠lbutlr 04 Mar '21

04 Mar '21

I've noticed several threads over the last year or so about last-login, and I was curious WHY people care about tracking this in the database. I can see wanting to know if a user has logged in recently, but this seems quite easy to tell by simply looking at the time stamp and/or contents of the mail spool for the user. For example, on my system I can look at the timestamps on the 'new' folders in the user's maildir to see if they are getting mail, and if the folders are empty, I have a time stamp of when they last checked that mailbox, giving me a pretty accurate time for when they last logged in. For example, looking at one user: # ls -lsdtr /path/to/user/maildir/{new,.**/new} I can see that the most recent "new" mailboxes were accessed on 02 Mar 14:25 and 03 Mar 01:45, and I can see that the latter mailbox has files in it and the former mailbox does not (just by the size, without doing an extra ls of those directories), so I know that the last time the user logged in was about 14:25 or later yesterday and that they definitely have not logged in in the last 3h05, which seems close enough to me. Am I missing some reason I would need/want to keep track of that specific login time separately? -- 'But you ain't part of it, are you?' said Granny conversationally.

LDA File Permissions
by David Morsberger 03 Mar '21

03 Mar '21

All, I am looking for an easy way to setup LDA so that it creates files with group read permission. Currently LDA/Sieve create the '.dovecot.lda-dupes’ file with ‘0600’. My backup process needs to be able to read the file because it runs as a user that is in the same group as the LDA process. I looked into the source code and the file is opened with mode ‘0666’ as " fd = open(lock_info->lock_path, O_RDWR | O_EXCL | O_CREAT, 0666); This implies it is a umask issue. What is the best way to view and set the umask value for the LDA process on Ubuntu 20.04? Thanks, David

Can Dovecot honor Outlook's "leave mail on server for X days" setting?
by Steve Dondley 03 Mar '21

03 Mar '21

I googled around for a quite bit but surprisingly came up empty for an answer to this question which I'm sure has been broached before. I've got a linux box running dovecot/postfix using maildir format. I was surprised to learn that a client that had many GBs of email was running POP3, not IMAP. It turns out they had a setting to delete POP3 mail after X days turned on but it just went ignored. I know this is not how POP3 is supposed to work, but is there a way to get dovecot to honor the user's settings in Outlook? Or should I just tell the client to turn this off and use a proper IMAP account?

Can master users retain private \Seen flags ?
by tuuialou 02 Mar '21

02 Mar '21

Hello, I am trying to setup a shared mailbox for a small team. Let's say Alice and Bob both need to read and answer sales(a)example.com. I would like Alice and Bob to retain private \Seen flags on sales(a)example.com. I know I can achieve that with INDEXPVT on shared or public mailboxes but I am not 100% happy with this solution because: - Thunderbird displays sales(a)example.com/Inbox and sales(a)example.com/Sent as "subscribed folders" within alice(a)example.com and bob(a)example.com. So Alice and Bob can't use the unified view of Thunderbird. - I need create a special identity in Alice and Bob Thunderbird's configuration so the sender is sales(a)example.com when Alice or Bob sends an email from sales(a)example.com (and not alice(a)example.com or bob(a)example.com) But I am not sure another email client is able to do that (on a mobile phone for example). - I need to add ACL rights if a new folder is created under sales(a)example.com. So I am now looking at the "master users" feature of Dovecot to replicate this MS Exchange setup https://www.en.its.aau.dk/instructions/Mail/shared-mailbox-thunderbird/ (alice(a)example.com and bob(a)example.com log is as sales(a)example.com) I achieved that but I don't know how to retain private \Seen flags so that Bob doesn't see an email as read even if Alice has marked it as read before. Is it possible to retain private \Seen flags with master users? If yes, how can I achieve that? Thank you for any help! PS: I posted the same question on https://forum.iredmail.org/post77816.html and https://forum.iredmail.org/topic13549-proposal-for-a-exchange-like-shared-m… but I couldn't get help and was advised to ask here.

Failed to map transaction log path - Stale file handle
by Gonzalo Palacios Goicolea 02 Mar '21

Hi All, We recently moved from RHEL6 to RHEL7 and updated dovecot from dovecot-2.2.10-1_14.el6.x86_64 to dovecot-2.2.36-8.el7.x86_64. We use NFS for storing the mail, and 5 servers running at the same time. Before updating dovecot we stopped the service and deleted all dovecot.index* files Now we're experiencing some problems.

Issue with masterauth
by Samuel Mutel 02 Mar '21

02 Mar '21

Hello, I would like to setup masterauth account to be able to connect to imap to log in as other users without password. My users are currently setup in LDAP and it is working correctly. I follow the page https://doc.dovecot.org/configuration_manual/authentication/master_users/ to setup this but I think I forgot something. When I try to login with telnet: Master user logging in as toto => it seems that i can connect with master user ldap(toto,127.0.0.1,<quR66Hm8KgB/AAAB>): invalid credentials => however ldap is request for password check, why ? Normmally the goal of master user is to not specify the password of the final user... Thanks.

Search is uninterruptable
by van der Kamp, John 01 Mar '21

01 Mar '21

Hi, When a user is doing a search, and the data is not indexed, then a search can take a very long time. It seems that search process is uninterruptable. The IMAP connection gets a status message with an ETA every so often, but an administrator on the server cannot stop it. Any SIGTERM or doveadm kick is ignored. Also, when the client times out (it seems clients are not seeing the ETA as a reason to keep the connection open) and the client disconnects is this search process continuing, even though any write to the socket would return an error. I believe the server is stuck in this loop: https://github.com/dovecot/core/blob/master/src/lib-storage/index/index-sea… Somehow the server needs to check for disconnected clients and let the session be kicked from the server too. You probably know better what to do about this then me.

dsync and sieve again

Hi, I'm starting to wonder if dsync is supposed to sync sieve scripts at all? Or should it work only as a part of replicator? Because I was not able to get it working on multiple Dovecot and Pigeon versions, and I see lots of replication/dsync and sieve related questions in the mailing list. I'm trying to get it to work using latest versions on http://repo.dovecot.org/ce-2.3-latest repo. The versions I am testing at the moment are: - Dovecot 2.3.13 (89f716dc2) - Pigeonhole 0.5.13 (cdd19fe3) It's a straightforward setup, nothing fancy. So the question is - is it supposed to work at all without replicator?
