Based on this you are not using SIS, so I wonder if those are some old emails when you were using SIS? Can you provide an example corpus of such mail? You can use e.g. https://www.dovecot.org/tools/dbox-anonymize.pl https://www.dovecot.org/tools/maildir-obfuscate.pl https://www.dovecot.org/tools/mbox-anonymize.pl https://www.dovecot.org/tools/mdbox-obfuscate.pl to obfuscate the mail.

Sorry, I have checked before I wrote first post. Based on docs - the path should be in /etc/dovecot/dovecot.conf or /etc/dovecot/conf.d/10-mail.conf (I have Ubuntu 16.04 LTS). I have some familiar lines in 10-mail.conf: #mail_attachment_dir = #mail_attachment_min_size = 128k #mail_attachment_fs = sis posix #mail_attachment_hash = %{sha1} but all these lines are commented out. So - in theory - dovecot does not store attachments anywhere but when I log into i.e. Roundcube, I have there mails with attachments. In Maildir/cur I see formatted files related with specific emails. These with attachments have specific hash at the bottom of content. As we could suppose they are hashed by sha1. But still no idea where are real files, which I can download after login to mailbox. 2018-08-28 18:38 GMT+02:00 Aki Tuomi <aki.tuomi(a)dovecot.fi>: > Check your configuration > > > > --- > Aki Tuomi > Dovecot oy > > -------- Original message -------- > From: Poliman - Serwis <serwis(a)poliman.pl> > Date: 28/08/2018 16:40 (GMT+02:00) > To: dovecot <dovecot(a)dovecot.org> > Subject: where are stored attachments > > Hi!

Perl Net::Doveadm
by Felipe Gasper 28 Aug '18

28 Aug '18

Hi all, In response to a discussion last week about API access--and notwithstanding Aki’s encouragement that integrators prefer the HTTP-based API--I’ve released a Perl module that facilitates access to Dovecot via the Doveadm protocol: https://metacpan.org/pod/Net::Doveadm I hope it’s useful. -Felipe Gasper Mississauga, ON

Update both virtual indexes & FTS indexes
by Daniel Miller 28 Aug '18

28 Aug '18

Will the following command: doveadm index -A '*' Ensure all Dovecot indexes are current (including virtual mailboxes) and also update FTS? Other than the time/resources needed to parse all users/mailboxes - is there a reason not to schedule this to run on a regular (hourly?) basis? My goal is to have my server constantly working...so my client isn't waiting for either virtual mailbox or Solr FTS updates. -- Daniel

I even chmod’ed the permissions after to rw for global and I get the same error/result. The file does appear to get written to. For example, lets say user u2.name creates a folder called “starbucks” and uses the IMAP commands to share it out to user operations. It seems to write to the acl_shared_dict file in /var/lib/dovecot/db/shared-mailboxes.db with an entry like > shared/shared-boxes/user/u2.name/operations > 1 And it writes to the ~/Maildir/.starbucks/dovecot-acl file for u2.user with an entry like: user=operations lrw So it appears to be working. However, if I log into Thunderbird with the user operations account and go to subscribe, I do not see “starbucks” in the list of available folders. And I still get the nfs_flush_chown error. Is there anything else I can be doing with the file/dir permissions?

mail-migration with dovadm sync/backup and mail_attachment_dir
by Ralf Becker 27 Aug '18

27 Aug '18

I need to run a mail-migration from a Dovecot with mail_attachment_dir / single instance storage enabled. As mailboxes and mail_attachment_dir are rsynced I would normally run a doveadm backup -u <user> -R -d dbox:<path to rsynced mailbox>/dbox How can I tell it the mail_attachment_dir the rsynced source / (reverse) destination uses? Or do I have to start a Dovecot process and use imapc for the migration?

HTTP API vs. doveadm

Is the Doveadm HTTP API considered stable for production use?
by James Beck 23 Aug '18

23 Aug '18

Hi, I'm running 2.2.34 in production (installed from Debian stretch backports) and want to rework some scripts. Can the HTTP API be considered stable in 2.2.34 please? The wiki says it is "considered experimental in v2.2.22" so I thought I'd check before writing API calls rather than a wrapper around doveadm! -- James Beck Andrews & Arnold Ltd Tel: 03333 400999

Re: Possible to set quota in size and number of messages

Hi Reio and list, It appears placing it at the end of the quota rules and then manually recalculating the quotas via doveadm has solved the problem! Configuration: plugin { quota = dict:User quota::file:%h/dovecot-quota quota_rule = *:storage=10G quota_rule1 = INBOX/Inbox:storage=+30M quota_rule2 = INBOX/Trash:storage=+30M quota_rule3 = INBOX/Deleted Messages:storage=+30M quota_rule4 = *:messages=100000 } Recalculate quotas: $ sudo doveadm quota recalc -u <account> Restart Dovecot and Apple Mail.

Possible to set quota in size and number of messages
by J Doe 21 Aug '18

21 Aug '18

Hello, I am using Dovecot 2.2.33.2 and am attempting to set quotas on mailboxes. I currently have the following: plugin { quota = dict:User quota::file:%h/dovecot-quota quota_rule = *:storage=10G quota_rule1 = INBOX/Inbox:storage=+30M quota_rule2 = INBOX/Trash:storage=+30M quota_rule3 = INBOX/Deleted Messages:storage=+30M } If I check the quota via Apple Mail version 11.5 (3445.9.1) on Mac OS X 10.13.6 by selecting “Get Account Info” it displays the correct quota size in bytes but also states “0 messages” (in that it states I can store 0 messages). Is there a way to signify to an IMAP client that the quota should be _EITHER_ 10 GB or 100,000 messages, just so a user doesn’t see that they can store a total of 0 messages ? My initial thought was to alter the previous quota settings by adding: quota_rule4 = INBOX:messages=100000 … and restarting Dovecot and Apple Mail, but upon checking the quota’s on the user’s account, I still see that a user can store 10 GB or 0 messages. Thanks, - J

Seems the delete opeation locks the mailbox list, and then the expunge create hits the same lock. Is this something we can fix by changing settings? Eg use another location for the expunge lock? -- Jan-Pieter Cornet <johnpc(a)xs4all.net> Systeembeheer XS4ALL Internet bv www.xs4all.nl

iOS Mail Client Not Copying to Sent Folder
by Asai 21 Aug '18

21 Aug '18

Greetings, We have many iOS clients, and some report that they’re having problems with iOS mail copying messages to their Sent folder. This happens 2 - 3 times per day, and the phone just says Sending and the client never knows if it sends. Client says apparently email DOES go out, but there is no recording of it. This is usually on our LAN. We’re not sure if this is solved via Postfix or Dovecot, or maybe something else, so I’m posting this message on both forums as a start. Can anyone point us in the right direction here? Running Postfix 2.11.1 and Dovecot ee 2.2.18.2 see doveconf -n below: # 2.2.18.2 (866bffbafde7): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.8 (73d4f6cd676a) # OS: Linux 2.6.32-358.el6.x86_64 x86_64 CentOS release 6.4 (Final) ext4 auth_mechanisms = plain login auth_verbose = yes auth_verbose_passwords = plain deliver_log_format = msgid=%m: from=%f: %$ lock_method = dotlock mail_home = /vmail/%d/%n/home mail_location = maildir:/vmail/%d/%n mail_plugins = " notify" 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 namespace { inbox = yes location = prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } plugin { mail_log_events = delete expunge copy mailbox_delete flag_change append mailbox_rename mail_log_fields = box msgid from flags sieve = /vmail/%d/%n/home/.dovecot.sieve sieve_before = /etc/dovecot/sieve/junk-spam.sieve sieve_default = /etc/dovecot/sieve/junk-spam.sieve sieve_dir = /vmail/%d/%n/home/sieve } protocols = imap lmtp sieve service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-master { group = vmail mode = 0660 user = vmail } unix_listener auth-userdb { mode = 0660 user = vmail } user = root } service imap-login { process_limit = 200 process_min_avail = 16 service_count = 0 vsz_limit = 0 } service managesieve-login { inet_listener sieve { port = 4190 } process_min_avail = 0 service_count = 1 vsz_limit = 64 M } ssl_cert = </etc/postfix/ssl/triata.pem ssl_key = </etc/postfix/ssl/triata.key userdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } protocol lda { hostname = domain.net mail_plugin_dir = /usr/lib64/dovecot/ mail_plugins = sieve postmaster_address = postmaster(a)domain.net } protocol imap { imap_idle_notify_interval = 24 mins mail_max_userip_connections = 60 } protocol sieve { mail_max_userip_connections = 10 managesieve_implementation_string = Dovecot Pigeonhole managesieve_logout_format = bytes=%i/%o managesieve_max_line_length = 65536 }

Strange problem on lmtp with dovecot 2.3.2.1
by davide marchi 20 Aug '18

20 Aug '18

Hi to all i have compiled and installed dovecot 2.3.2.1 on debian 6 with success but now i'm facing a strange problem on communication from postfix installed on server A with dovecot installed on server B (which version is 2.3.2.1). All incoming emails delivered from esternal from server A to server B with LMTP is rejected with this message error "smtpgw postfix/lmtp[1772]: 6194CA00B3: to=<xxxxxxxxxxxx(a)mail.cgilfe.it>, relay=192.168.10.50[192.168.10.50]:24, delay=0.02, delays=0/0.01/0.01/0, dsn=5.5.4, status=undeliverable (host 192.168.10.50[192.168.10.50] said: 501 5.5.4 Invalid FROM: Missing domain (in reply to MAIL FROM command))" I cant identify what is the problem , for now i have bypassed lmtp using smtp but my goal is returning to lmtp that i have used since old versions of dovecot.

systemd also listening on imaps port
by Kai Schaetzl 20 Aug '18

20 Aug '18

I noticed that most of the time with dovecot 2.3 I get this output, showing systemd listening on the port as well: lsof -i TCP:993 systemd 1 root 38u IPv4 3388360574 0t0 TCP *:imaps (LISTEN) systemd 1 root 41u IPv6 3388360575 0t0 TCP *:imaps (LISTEN) dovecot 11607 root 5u IPv4 3388360574 0t0 TCP *:imaps (LISTEN) dovecot 11607 root 6r IPv6 3388360575 0t0 TCP *:imaps (LISTEN) Sometimes I don't get the extra systemd lines, but I can't reproduce it now. It's only for port 143 and 993. Other ports show only two dovecot processes. Operation seems to be normal. Is this how it is supposed to be with dovecot 2.3? This is Ubuntu 16.04.

So, if it fails to transform (although bigger) the machine hasn't enough entropy (because it's quite new?)? I'm generating now on the original machine from last year which is still going on while a second run on one of the machines where it failed to transform is already finished. So, that would indicate it has less entropy? Can I re-use the ssl-parameters.dat for several machines or should I create a new one for each? For the time being I just copied the dh.pem over, to get going, but I guess this should only be a temporary workaround? Thanks! Kai

imapsieve: Change message flags on COPY
by Leandro Lucarella 20 Aug '18

20 Aug '18

Hello, I'm trying to do a simple thing using imapsieve, I want messages to be marked as read when moved to certain folders (Trash, Archive, Spam). All the set up to run the imapsieve script works perfectly, but I'm having trouble to make changes effective. As the RFC says, IMAP messages are immutable, but it's not clear to me reading the specs if this applies to IMAP flags too, as one can really change flags in IMAP without having to create a new (modified) message, I guess this is an exception? 3.8. The "setflag", "deleteflag", and "removeflag" Actions Implementations of IMAP events in Sieve MUST also support the imap4flags extension [RFC5232], and the actions associated with it are all applicable to any case that falls under IMAP events in Sieve. It is worth noting also that the "hasflag" test that is defined in the imap4flags extension might be particularly useful in scripts triggered by flag changes ("hasflag" will see the new, changed flags). The flag changes behave as though a client had made the change. As explained above, in order to avoid script loops, flag changes that are made as a result of a script that was itself invoked because of flag changes SHOULD NOT result in another script invocation. In any case, implementations MUST take steps to avoid such loops. https://tools.ietf.org/html/rfc6785 Should changing flags just work for imapsieve? I even tried to use fileinto to explicitly save a new message (as far as I understand if I use fileinto the implicit keep should be cancelled, so the original message should be flagged as \Deleted (this is another hint that changing flags in immutable messages should be fine), and a new message should be created with the changed flags. But this is not happening, after moving the message I see unseen message still not flagged with \Seen. This is my imapsieve script: ---------------------------- require ["variables", "imap4flags", "fileinto", "vnd.dovecot.imapsieve", "vnd.dovecot.environment", "vnd.dovecot.execute", "vnd.dovecot.debug"]; if header :matches "Subject" "*" { set "subject" "${1}"; } if header :matches "From" "*" { set "from" "${1}"; } if environment :matches "imap.mailbox" "*" { set "dst" "${1}"; } debug_log "IMAPSIEVE TEST ---------------------"; debug_log "subject:${subject}"; debug_log "from:${from}"; debug_log "dst:${dst}"; debug_log "END IMAPSIEVE TEST -----------------"; if string :is "${dst}" ["Archive", "Trash", "Spam", "Sent"] { debug_log "Moved to ${dst}, marking as read: '${subject}' <${from>"; setflag "\\Seen"; fileinto "${dst}"; } ---------------------------- This is the log: Aug 16 10:31:51 alerce dovecot: imap(luca): Debug: Archive: Mailbox opened because: UID MOVE Aug 16 10:31:51 alerce dovecot: imap(luca): Debug: Mailbox INBOX: Opened mail UID=13304 because: copying Aug 16 10:31:51 alerce dovecot: imap(luca): Debug: imapsieve: mailbox Archive: MOVE event Aug 16 10:31:51 alerce dovecot: imap(luca): Debug: imapsieve: Matched static mailbox rule [1] Aug 16 10:31:51 alerce dovecot: imap(luca): Debug: sieve: file storage: Using Sieve script path: /home/luca/sieve/imapsieve.sieve Aug 16 10:31:51 alerce dovecot: imap(luca): Debug: sieve: file script: Opened script `imapsieve' from `/home/luca/sieve/imapsieve.sieve' Aug 16 10:31:51 alerce dovecot: imap(luca): Debug: sieve: Opening script 1 of 1 from `/home/luca/sieve/imapsieve.sieve' Aug 16 10:31:51 alerce dovecot: imap(luca): Debug: sieve: Loading script /home/luca/sieve/imapsieve.sieve Aug 16 10:31:51 alerce dovecot: imap(luca): Debug: sieve: Script binary /home/luca/sieve/imapsieve.svbin successfully loaded Aug 16 10:31:51 alerce dovecot: imap(luca): Debug: sieve: binary save: not saving binary /home/luca/sieve/imapsieve.svbin, because it is already stored Aug 16 10:31:51 alerce dovecot: imap(luca): Debug: sieve: Executing script from `/home/luca/sieve/imapsieve.svbin' Aug 16 10:31:51 alerce dovecot: imap(luca): sieve: imapsieve: line 11: DEBUG: IMAPSIEVE TEST --------------------- Aug 16 10:31:51 alerce dovecot: imap(luca): sieve: imapsieve: line 12: DEBUG: subject:Ihr DHL Paket wurde zugestellt.

I tried adding a stop; too, as suggested in this thread https://www.dovecot.org/list/dovecot/2017-April/107658.html, but the effect is the same, the message in Archive is still not flagged as \Seen. So the main question here is if changing IMAP flags in imapsieve scripts shouldn't just work, without even having to use fileinto, and if not, why isn't even using fileinto working? PS: Please Cc me, I'm not in the list. Thanks! -- Leandro Lucarella (Luca) https://llucax.com

creation of ssl-parameters fails

I did that the last time one year ago, now on another machine with the same software (Ubuntu 16.04) it fails. openssl dhparam 4096 > /var/lib/dovecot/ssl-parameters.dat dd if=/var/lib/dovecot/ssl-parameters.dat bs=1 skip=88 | openssl dhparam -inform der > /etc/dovecot/dh.pem last command fails with 681+0 records in 681+0 records out 681 bytes copied, 0,00278343 s, 245 kB/s unable to load DH parameters 139858178938624:error:0D0680A8:asn1 encoding routines:asn1_check_tlen:wrong tag:../crypto/asn1/tasn_dec.c:1129: 139858178938624:error:0D07803A:asn1 encoding routines:asn1_item_embed_d2i:nested asn1 error:../crypto/asn1/tasn_dec.c:289:Type=DH ssl-parameters.dat is more than double the size as the one that worked. And that one I can still transform: 272+0 records in 272+0 records out 272 bytes copied, 0,00105017 s, 259 kB/s So, something with openssl dhparam 4096 > /var/lib/dovecot/ssl-parameters.dat must be wrong. But what? https://wiki.dovecot.org/SSL/DovecotConfiguration tells to use this command. Thanks! Kai

dovecot and postfix, help?
by Christy S 19 Aug '18

19 Aug '18

Hi all, First a disclaimer. I have played with linux off and on for years, but this is my first time trying to run a server completely on my own from start to finish, well it's on a vps, but still. I'm pretty techie, but a lot of this stuff is new to me, so I apologize for any *duh!* questions. That said, I've so far installed dovecot, postfix, wordpress, and related programs mostly successfully by following tutorials. I say mostly successfully, because I'm having a really hard time trying to get dovecot and postfix to behave together, and I'm about at the end of what I know how to find on google. If you're still with me and not groaning at yet another newbie asking wtf did I do wrong questions, thank you! My basic setup is running ubuntu 18 with up to date dovecot and postfix. Sasl is installed, and I'm using a custom domain with all records successfully pointing to the VPS. As I mentioned, I've been following tutorials. My goal is to have a mail server which can send and receive emails using this custom domain both from the shell and, much more often, from my primary computer using thunderbird. As there will likely only be two of us using this, I'm completely fine with the setup using mailboxes that actually have linux accounts. I'm also using maildir as the mailbox type. Furthermore, I want to make sure to use ssl on any mail connections.. Normal passwords but ssl being used. So, following one tutorial I set up postfix and dovecot, then went to test it. The result was that while on the shell, I could send email to my gmail account from the domain and receive it just fine. I could also send mail from my gmail account to the domain and receive it on the shel. I even managed to get imap to work, so I could receive domain emails in thunderbird, after playing around with tb's settings. However, if using tb I attempted to send an email using the custom domain, smtp failed to connect. I verified with my VPS provider that no, they do not block port 25, 465 or 587. I also verified that at&t, my home ISP, does not block outgoing smtp traffic, considering I am using google's for my gmail account. After hitting google again, I realized two things. One, for some reason port 25 never got opened on UFW, so I fixed that. Second, for some reason in all the stuff I did, postfix never got configured to use SSL. I found yet another tutorial, and ran through it to set up SSL with postfix. However, in doing this I had to change a path for sasl, only to find out later that doing that broke dovecot! Imap completely and utterly stopped behaving. Back to google again, and this time I found something a bit more up to date which explained how to interconnect postfix and dovecot. It goes through using mysql too, but I don't need that, so I skipped that part. Changed the sasl path back to what it should be, told dovecot and postfix to talk to each other and... Nope, still nothing. I saw a warning that I should not use different certificates for postfix and dovecot, so I told dovecot to look at the smtpd certificate that I made. Not sure if that's what's breaking this or something completely different, as I'm also brand new to the ssl certificate creation process. So, here's the current status of using thunderbird with my domain. mail sent from gmail to new domain, never comes back in thunderbird but doesn't bounce, either. Mail sent via thunderbird to gmail from domain, works, but shows up as from my gmail domain as well, which makes me think it's defaulting to the gmail account even though the domain's smtp info is set up. This could be because just before writing this message, I got the accept this certificate dialog over and over again for the domain and had to cancel out of it. One final point. I looked at /var/log/mail.log and, while at first I found an error in the path to one of the certificates, once I fixed that no error shows up. I restarted both postfix and dovecot, tried refreshing thunderbird and still no emails showed up. I see the connection in the log, but no errors. Anyone have ideas? Even maybe just point me in the right direction for what to check?

update to my first email
by Christy S 19 Aug '18

19 Aug '18

Alright so after checking logs, rebooting the vps because why not, and removing and re-adding the account in thunderbird... Now nothing is working other than sending mail from gmail to the domain. imap does not pick up the email and trying to send with the domain just plain fails, saying it can't connect to the server. Honestly, tempted to uninstall dovecot, sasl and postfix and start again, but I don't want to run into the same issues with conflicting tutorials. Does anyone know of a good source of how to do this that's fairly recent? I'll keep searching, but all of the outdated info is kind of frustrating. If anyone has replied to me I haven't gotten it yet, so I'm not ignoring anything you may have said. For now going to give this a break. I've been working on it literally all day! :) Christy

"nologin" field set leads to internal failure
by postminion＠dicksinmyan.us 17 Aug '18

17 Aug '18

Hi, I've tried to use the "nologin" extra password-db field as specified here: https://wiki.dovecot.org/PasswordDatabase/ExtraFields/NoLogin Due to lack of exact documentation, I've tried to use `nologin`='y' for users that can't login, and setting `nologin`='n' for normal users. Apparently setting it to NULL for normal users would have been correct, as I've found out. Maybe write that on the above website. Anyway, login didn't work for a user with `nologin`='n' set. Trying to debug a normal user being unable to login, the log (mail.log) says: dovecot: imap-login: Disconnected (internal failure, 4 successful auths): user=<test(a)example.com>, method=PLAIN, rip=<ip6>, lip=<ip6>, TLS, session=<session> What I'm expecting it to say would be something like "user not allowed to login". I'm considering this a problem because of "Dovecot always logs a detailed error message if something goes wrong." as written here: https://wiki2.dovecot.org/Logging For the record, setting auth_debug=yes and mail_debug=yes gave the following line in the logs somewhere, from which I was able to figure out that NOLOGIN was the problem: dovecot: auth: Debug: client passdb out: OK#011<id>#011user=test(a)example.com#011nologin Thank you. dovecot -n output: --snip-- # 2.2.27 (c0f36b0): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.16 (fed8554) # OS: Linux 4.9.0-7-amd64 x86_64 Debian 9.5 auth_default_realm = example.com base_dir = ... listen = *,[v6] login_greeting = ... mail_home = .../%d/%n/ mail_location = maildir:~/mail/:INDEX=MEMORY mail_plugins = trees mail_temp_dir = ... namespace inbox { inbox = yes location = prefix = } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocols = imap lmtp recipient_delimiter = -+ service auth { unix_listener ... { group = postfix mode = 0660 user = postfix } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 0 } service_count = 1 } service lmtp { unix_listener ... { group = postfix mode = 0600 user = postfix } user = vmail } ssl = required ssl_cert = <... ssl_cipher_list = ... ssl_dh_parameters_length = 4096 ssl_key = # hidden, use -P to show it userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } --snap--

sdbox filesystem backup potential excludes
by Daniel Miller 17 Aug '18

17 Aug '18

When doing a filesystem backup of an moderate sdbox mailstore (300GB) - are there any files that can be safely excluded from the backup? Like *.log or *.backup? Or are they all "vital" for recovery? I'm already excluding the sdbox/virtual folders as it looks like they get created and updated as needed. -- Daniel

imapsieve wrong matches on APPEND cause
by Alex Cherevko 17 Aug '18

17 Aug '18

Hello, I'm experiencing some strange problem with imapsieve mailbox rules matching. I have Ubuntu Server 18.04.1 LTS with Postfix 3.3.0, Dovecot 2.2.33.2 and Rspamd 1.7.9. The problem occurs with Microsoft Outlook 2016 mail client. When moving with Outlook, APPEND event is logged instead of MOVE. However, when moving with another client, MOVE event is logged. So without APPEND event in causes in plugin section of dovecot.conf no rule is matched at all. If I add APPEND event into causes in plugin section of dovecot.conf, then for some reason imapsieve matches both rules on move from Inbox to Spam and no rules on move from Spam to Inbox. Matching both rules attempts to run both learn_spam and learn_ham. First one works and second logs error (which is correct). On attempt to move message from Spam to Inbox imapsieve not matching any rule at all and thus learning is not working. Could you please let me know how to fix this? More details. Here is what I have in my plugin section of dovecot.conf: ---------------------------------------- %< ---------------------------------------- plugin { imapsieve_mailbox1_before = file:/var/vmail/sieve/global/learn-spam.sieve imapsieve_mailbox1_causes = COPY APPEND imapsieve_mailbox1_from = Inbox imapsieve_mailbox1_name = Spam imapsieve_mailbox2_before = file:/var/vmail/sieve/global/learn-ham.sieve imapsieve_mailbox2_causes = COPY APPEND imapsieve_mailbox2_from = Spam imapsieve_mailbox2_name = Inbox sieve = file:/var/vmail/sieve/%d/%n/scripts;active=/var/vmail/sieve/%d/%n/active-scr ipt.sieve sieve_before = /var/vmail/sieve/global/spam-global.sieve sieve_global_dir = /var/vmail/sieve/global/ sieve_global_extensions = +vnd.dovecot.pipe +vnd.dovecot.environment +vnd.dovecot.debug sieve_pipe_bin_dir = /usr/bin sieve_plugins = sieve_imapsieve sieve_extprograms } ---------------------------------------- %< ---------------------------------------- I also have Trash, Drafts, Sent and Spam mailboxes defined in dovecot.conf. So when I try to move actual spam message from Inbox to Spam folder, this is what I see in dovecot.log: ---------------------------------------- %< ---------------------------------------- Debug: imapsieve: mailbox Spam: APPEND event ---------------------------------------- %< ---------------------------------------- So before I added "APPEND" into above imapsieve_mailbox1_causes and imapsieve_mailbox2_causes imapsieve was not matching rules at all. But after I added APPEND, here is what happens. In case I move message from Inbox to Spam both rules are matched and dovecot attempts to run both rules: ---------------------------------------- %< ---------------------------------------- Debug: INBOX: Mailbox opened because: SELECT Debug: Spam: Mailbox opened because: SELECT Debug: imapsieve: mailbox Spam: APPEND event Debug: sieve: Pigeonhole version 0.4.21 (92477967) initializing Debug: sieve: Sieve imapsieve plugin for Pigeonhole version 0.4.21 (92477967) loaded Debug: sieve: Sieve Extprograms plugin for Pigeonhole version 0.4.21 (92477967) loaded Debug: imapsieve: Static mailbox rule [1]: mailbox=`Spam' from=`*' causes=(APPEND) => before=`file:/var/vmail/sieve/global/learn-spam.sieve' after=(none) Debug: imapsieve: Static mailbox rule [2]: mailbox=`*' from=`Spam' causes=(APPEND) => before=`file:/var/vmail/sieve/global/learn-ham.sieve' after=(none) Debug: imapsieve: Matched static mailbox rule [2] Debug: imapsieve: Matched static mailbox rule [1] Debug: sieve: file storage: Using Sieve script path: /var/vmail/sieve/global/learn-spam.sieve Debug: sieve: file script: Opened script `learn-spam' from `/var/vmail/sieve/global/learn-spam.sieve' Debug: sieve: file storage: Using Sieve script path: /var/vmail/sieve/global/learn-ham.sieve Debug: sieve: file script: Opened script `learn-ham' from `/var/vmail/sieve/global/learn-ham.sieve' Debug: sieve: Opening script 1 of 2 from `/var/vmail/sieve/global/learn-spam.sieve' Debug: sieve: Loading script /var/vmail/sieve/global/learn-spam.sieve Debug: sieve: Script binary /var/vmail/sieve/global/learn-spam.svbin successfully loaded Debug: sieve: binary save: not saving binary /var/vmail/sieve/global/learn-spam.svbin, because it is already stored Debug: sieve: Executing script from `/var/vmail/sieve/global/learn-spam.svbin' Debug: sieve: action pipe: running program: rspamc Debug: Mailbox Spam: Opened mail UID=12 because: mail stream Debug: waiting for program `/usr/bin/rspamc' to finish after 0 msecs Debug: sieve: Opening script 2 of 2 from `/var/vmail/sieve/global/learn-ham.sieve' Debug: sieve: Loading script /var/vmail/sieve/global/learn-ham.sieve Debug: sieve: Script binary /var/vmail/sieve/global/learn-ham.svbin successfully loaded Debug: sieve: binary save: not saving binary /var/vmail/sieve/global/learn-ham.svbin, because it is already stored Debug: sieve: Executing script from `/var/vmail/sieve/global/learn-ham.svbin' Debug: Spam: Mailbox opened because: lib-lda delivery Debug: Spam: Mailbox opened because: SELECT ---------------------------------------- %< ---------------------------------------- And of course I'm getting the following in the log file: ---------------------------------------- %< ---------------------------------------- Error: sieve: learn-ham: line 2: duplicate pipe "rspamc" action not allowed (previously triggered one was here: learn-spam: line 3) Error: sieve: Execution of script /var/vmail/sieve/global/learn-ham.sieve failed ---------------------------------------- %< ---------------------------------------- In case I move message from Spam to Inbox on rule is matched at all: ---------------------------------------- %< ---------------------------------------- Debug: INBOX: Mailbox opened because: SELECT Debug: imapsieve: mailbox INBOX: APPEND event Debug: sieve: Pigeonhole version 0.4.21 (92477967) initializing Debug: sieve: Sieve imapsieve plugin for Pigeonhole version 0.4.21 (92477967) loaded Debug: sieve: Sieve Extprograms plugin for Pigeonhole version 0.4.21 (92477967) loaded Debug: imapsieve: Static mailbox rule [1]: mailbox=`Spam' from=`*' causes=(APPEND) => before=`file:/var/vmail/sieve/global/learn-spam.sieve' after=(none) Debug: imapsieve: Static mailbox rule [2]: mailbox=`*' from=`Spam' causes=(APPEND) => before=`file:/var/vmail/sieve/global/learn-ham.sieve' after=(none) Debug: INBOX: Mailbox opened because: SELECT ---------------------------------------- %< ---------------------------------------- With best regards, Alex

If the goal is to ensure privacy using a third-party storage provider (and assuming mail handlers are implictly trusted), it seems more productive to invest effort into block/FS level encryption that comprehensively protects all data.

Confusing search / caps - non caps different results
by Götz Reinicke 15 Aug '18

15 Aug '18

Hi, I have some troubles with searching and could not find an answer yet. The search term is „istop“ in the subject. The client was SOGo. We run the recent dovecot, with solr backend and milder with zlib compression. Searching for all small letters „istop“ shows up no hit. Searching with a capital „S“ „iStop“ shows all messages back 10 years ago. Sprachig for „istopmotion“ all messages show up, wether the subject contains caps or non caps at all. I did a telnet to our dovecot and searched by hand for all three terms: 8 search Subject istop * SEARCH 8 OK Search completed (0.025 + 0.000 + 0.022 secs). 9 search subject iStop * SEARCH 544 604 654 662 910 1394 1471 1474 5493 9 OK Search completed (0.028 + 0.000 + 0.023 secs). 10 search subject istopmotion * SEARCH 544 604 654 662 910 1471 1472 1474 5493 10 OK Search completed (0.027 + 0.000 + 0.023 secs). Any hints or suggestion is welcome as I m very confused and lost. Thanks and regards . Götz

Recommendations for backup methods
by Daniel Miller 14 Aug '18

14 Aug '18

I've been re-thinking my backup strategy - I wanted to see what input others have. At this time - I'm using sdbox as the primary storage format and running on a single server. Previously, all my backups were simple filesystem backups. Either inotify-based or cron-based. The whole mail folder structure would then be copied to a remote storage site. I've changed services - I now use OpenDrive for the remote storage and can access the remote drive as a mounted folder via WebDAV. I also now use a cron-based series of restic jobs for the backup processing. Because I have some large folders - both personal & business letters going back quite some time as well as mailing list archives - some mail folders can be quite sizable. Now I'm wondering, between sdbox's support for alternate locations and the ability to use different storage formats via namespaces - perhaps I should setup archive folders that are stored differently to improve backup performance. Maybe maildir or even mbox for the archive folders - I create one per year? Any comments? Experiences? -- Daniel

Hello. I can move messages with doveadm like this: doveadm move -A Archive mailbox INBOX/* before 2018-02-01 but if inbox has a subfolders then subfolders structure does not move to Archive only messages. Is there a way to move messages to the same folder in new destination? Thanks.

[trees-plugin] - Dovecot index gets corrupted, when using maildir and recievend and accessing mail at the same time
by neutron 11 Aug '18

11 Aug '18

Hello dovecot team, at first I want to thank you the awesome dovecot software. I'm currently researching and developing the trees plugin (https://0xacab.org/riseuplabs/trees) In the future I would love to package this software for debian. I run into a problem, which I can not fix by myself, that's why I'm reaching out to you. The plugin is producing a reproducible error, when using dovecots mailbox format maildir, and receiving and accessing mail at the same time. I'm searching for additional information to fix that. I know that it's may not the scope of the mailing list to support external plugins, but since you are the experts, I thought I should ask at least. Trees Plugin: =================== The plugin adds individually encrypted mail storage to the Dovecot IMAP server. It encrypts all (incoming and outgoing) mail on the mail server with a key, which can only be accessed with the users password. So the server operator is not able to see any mail content, if it's saved on the hard disk. Bug Description: =================== I'm using a postfix dovecot setup with the enabled trees plugin with the mailboxformat maildir. When I'm receiving and accessing mail at the same time, the dovecot index gets corrupted. For accessing those mail I use Thunderbird. Example corruption: > ug 4 09:55:15 trees dovecot: imap-login: Login: user=<treesenabled(a)trees.testing>, method=PLAIN, rip=192.168.22.1, lip=192.168.22.77, mpid=4643, TLS, session=<w0OCCplyhLLAqBYB> > Aug 4 09:55:15 trees dovecot: imap(treesenabled(a)trees.testing): Debug: trees plugin initialized > Aug 4 09:55:15 trees dovecot: imap(treesenabled(a)trees.testing): Connection closed in=506 out=495 > Aug 4 09:55:15 trees dovecot: imap(treesenabled(a)trees.testing): Error: Maildir filename has wrong S value, renamed the file from /var/vmail/trees.testing/treesenabled/Maildir/cur/1533376515.M379290P4641.trees,S=1456,W=748:2, to /var/vmail/trees.testing/treesenabled/Maildir/cur/1533376515.M379290P4641.trees,S=783:2, > Aug 4 09:55:15 trees dovecot: imap(treesenabled(a)trees.testing): Error: Corrupted index cache file /var/vmail/trees.testing/treesenabled/Maildir/dovecot.index.cache: Broken physical size for mail UID 1 in mailbox INBOX: read(/var/vmail/trees.testing/treesenabled/Maildir/cur/1533376515.M379290P4641.trees,S=1456,W=748:2,) failed: Cached message size larger than expected (1456 > 728, box=INBOX, UID=1, cached Message-Id=<4ae8ea2c-17ac-37d5-9b9e-b32c6edc777a(a)trees.testing>) > Aug 4 09:55:15 trees dovecot: imap(treesenabled(a)trees.testing): Panic: file istream.c: line 175 (i_stream_read): assertion failed: (old_size <= _stream->pos - _stream->skip) > Aug 4 09:55:15 trees dovecot: imap(treesenabled(a)trees.testing): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x95e92) [0x7fa88e2afe92] -> /usr/lib/dovecot/libdovecot.so.0(+0x95f8d) [0x7fa88e2aff8d] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7fa88e245a91] -> /usr/lib/dovecot/libdovecot.so.0(i_stream_read+0x290) [0x7fa88e2baf20] -> /usr/lib/dovecot/libdovecot.so.0(i_stream_read_data+0x3d) [0x7fa88e2bb72d] -> /usr/lib/dovecot/libdovecot.so.0(message_get_body_size+0xfd) [0x7fa88e29ab6d] -> /usr/lib/dovecot/libdovecot-storage.so.0(index_mail_init_stream+0x220) [0x7fa88e5eb3d0] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x66fc0) [0x7fa88e5a2fc0] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_get_stream_because+0x5d) [0x7fa88e572e1d] -> /usr/lib/dovecot/libdovecot-storage.so.0(imap_msgpart_open+0x536) [0x7fa88e6264f6] -> dovecot-trees.testing/imap(+0x1ebbc) [0x559b794f1bbc] -> dovecot-trees.testing/imap(+0x1cfb6) [0x559b794effb6] -> dovecot-trees.testing/imap(imap_fetch_more+0x39) [0x559b794f10e9] -> dovecot-trees.testing/imap(cmd_fetch+0x33b) [0x559b794e2d9b] -> dovecot-trees.testing/imap(command_exec+0xa5) [0x559b794ee735] -> dovecot-trees.testing/imap(+0x199c2) [0x559b794ec9c2] -> dovecot-trees.testing/imap(+0x19a4c) [0x559b794eca4c] -> dovecot-trees.testing/imap(client_handle_input+0x1b5) [0x559b794ece55] -> dovecot-trees.testing/imap(client_input+0x86) [0x559b794ed3c6] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x52) [0x7fa88e2c49f2] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x109) [0x7fa88e2c6029] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x3c) [0x7fa88e2c4a8c] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7fa88e2c4c38] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7fa88e24bfd3] -> dovecot-trees.testing/imap(main+0x328) [0x559b794dfe68] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf1) [0x7fa88de9b2e1] -> dovecot-trees.testing/imap(_start+0x2a) [0x559b794dffea] > Aug 4 09:55:15 trees dovecot: imap(treesenabled(a)trees.testing): Fatal: master: service(imap): child 4633 killed with signal 6 (core dumps disabled) The behavior does not occur, when I'm using maildir and access my mail after receiving it. It also does not occur with other mailbox formats such as mbox, sdbox and mdbox I opened a bug report at the trees repository, which is more detailed ( https://0xacab.org/riseuplabs/trees/issues/24 ). There I described how it's possible to reproduce this error. In the trees repo there is also a vagrant box, with which it's possible to spin up the exact same setup. Questions: =================== 1.) Do you know what could possibly lead to the the larger cached message size, when accessing this mail via imap? 2.) Why does these sizes differ from each other? Mail size from the log is: 'S=1456,W=748:2' or 'renamed to ...S=783:2'. But I do not see where the size of '728' come from? 3.) Do you have a hint what could lead to this behavior and how could I solve this error? Unrelated but also interesting for trees usage: 4.) Is there a tool, with which you can export and import mail to the same inbox? Background: After activation for an existing mail user, only new outgoing and incoming mail is encrypted. So it would be necessary to "re-save" the existing mail again in this mailbox, to pipe all mails through the encryption process. I know that there is dsync, imapsync and several different tools, but I'm not sure what is the best tool for the job, or if I should use dsync to do a 3 way sync? > existing_mailbox(a)server.com > tmp_mailbox(a)server.com > existing_mailbox(a)server.com Thank you: =================== Thank you for time reading this mail :) Dovecot Config: =================== # 2.2.27 (c0f36b0): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.16 (fed8554) # OS: Linux 4.9.0-6-amd64 x86_64 Debian 9.4 ext4 auth_mechanisms = plain login instance_name = trees.testing login_greeting = trees.testing ready. mail_gid = 5000 mail_location = maildir:/var/vmail/%Ld/%Ln/Maildir mail_plugins = " quota trees" mail_uid = 5000 mailbox_list_index = yes namespace inbox { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = subscribe autoexpunge = 30 days special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { auto = subscribe autoexpunge = 30 days special_use = \Trash } prefix = } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocols = " imap pop3" service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } unix_listener auth-userdb { group = vmail mode = 0660 } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } process_min_avail = 4 } service imap { executable = imap } service pop3 { executable = pop3 } ssl = required ssl_cert = </etc/ssl/certs/ssl-cert-snakeoil.pem ssl_cipher_list = ALL:!LOW:!RC4:!EXP:!aNULL ssl_dh_parameters_length = 2048 ssl_key = # hidden, use -P to show it ssl_prefer_server_ciphers = yes userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql }

dovecot stats-writer socket permissions
by Scott Ruckh 11 Aug '18

11 Aug '18

I have seen this thread about being able to run doveadm as a non-root user, but I don't understand the solution even though I have seen other pages give this link as the solution. http://bit.ly/2MC5oq9 What configuration is necessary so that I can set the permissions on /var/run/dovecot/stats-writer socket-file so when dovecot starts my virtual mail account has read/write access? I saw another page about adding service stats { } Although I set user, group, and permissions, it did not seem to have any effect on the permissions when I restarted dovecot. Thank You.

limit sharing ability to certain users
by Simeon Ott 10 Aug '18

10 Aug '18

Hello Is it possible to limit the ability of sharing it’s own mailboxes to only a few users? We have a few sensitive mailboxes of users where the ability to share via IMAP SETACL should be prevented. I tried the following so far… doveadm acl remove -u test(a)onnet.ch INBOX user=test(a)onnet.ch admin but when doing this the admin rights are still there doveadm acl rights -u test(a)onnet.ch INBOX vmail@buserver:~$ doveadm acl rights -u test(a)onnet.ch INBOX Rights lookup read write write-seen write-deleted insert post expunge create delete admin Thanks in advance for your help Simeon
