Dsync config help
by Jean-Luc Wasmer 01 Sep '16

01 Sep '16

Hi, I’m having a hard time with the http://wiki2.dovecot.org/Replication page. - for a master-master setup, does the configuration need to be mirrored on both masters? - after aggregating unrelated sections of the wiki page, there seems to be 3 different values for “mail_replica": - "remote”: for SSH - “remoteprefix": for SSH wrapper - “tcp”: for TCP connection using the Doveadm protocol Is this correct? - what’s the purpose of the replicator VS aggregator VS doveadm services? Who talks to who? Where can I find documentation about their configuration (i.e. not examples) - most examples are for a single vmail user setup… what should be done when using system accounts? Thanks, Jean-Luc

autoexpunge clarification
by Michael Fox 01 Sep '16

01 Sep '16

I'm trying to understand autoexpunge, but the documentation is just not clear. Hopefully, someone can clear up a few questions. http://wiki.dovecot.org/MailboxSettings says the following: autoexpunge=<time>: (v2.2.20+) Automatically at user deinitialization expunge all mails in this mailbox whose saved-timestamp is older than <time> (e.g. autoexpunge=30d). This removes the need for expire plugin <http://wiki.dovecot.org/Plugins/Expire> if you don't care that the expunging may not always happen in time. What does "at user deinitialization" mean? What does "if you don't care that the expunging may not always happen in time" mean? I read the sub-bullets but they just aren't clear. When exactly does autoexpunge occur? Thanks, Michael

Help setting up IMAP account in Outlook 2016
by Spiro Angeli 01 Sep '16

01 Sep '16

Hi, I need help setting up mail clients for my email accounts running on dovecot ver 2.2.18 on CentOS release 6.8 (Final) and Plesk Web Admin Edition in Italian. For better reading I posted a forum thread where you can get all detail info: Help setting up IMAP account in Outlook 2016 Forum link: http://www.emailquestions.com/threads/help-setting-up-imap-account-in-outloo k-2016.13439 I was advised to " ask dovecot list for help with the IMAP server. " So I did and a user kindly suggested me to customize "15-mailboxes.conf " file. I have some technical questions I need to ask. Hope someone knows the answers. As Plesk continuously updates itself and manages most of the server the majority of CentOS fils report this lines on top of each file: ## ## Authentication for Plesk mail users. ## # PLEASE DON'T EDIT ANYTHING IN THIS FILE! ANY CHANGES WILL BE LOST ON UPGRADE. So if I customize this "15-mailboxes.conf " I need to make sure that Plesk does not overwrite. Also I need to make sure that it gets updated if Dovecot changes in its settings. So, my first question is: how do I manage to keep this "15-mailboxes.conf " file updatable by OS (when I update system) but at the same time retain customizations upon system updates? Second question has to do with customization: Please consult attachment for this question a. I wish to see existing server folders (Draft, Sent, Spam, Trash) on my MS Outlook mail client software only in Italian and not in English. What should I do? Roundcube displays them in Italian. AquaMail (on Android) displays them in Italian. b. I was told to solve this server wise and not mail box per mailbox. Is this correct? c. Can you please share a complete customized code, for my needs, for this "15-mailboxes.conf " so I can learn from it? Thank you, Spiro

ACL List uses wrong namespace for permissions
by Harald Leithner 31 Aug '16

31 Aug '16

Hi, I'm using dovecot 2.2.devel (11c704a) with lazyexpunge and shared Mailboxes, this seams to work since the latest patch. There is only one problem creating the correct dovecot-acl-list, if I login as the normal user that has set permissions for another user everything is ok. If I login with the same user but with a modified roundcube that uses the #EXPUNGED Namespace as root, dovecot overrides the correct dovecot-acl-list with an empty version. I think this is the most interesting part of the log: 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: fs: root=/srv/storage1/vmail/company/628, index=, indexpvt=, control=, inbox=, alt= 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl: initializing backend with data: vfile 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl: acl username = user(a)company.at 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl: owner = 1 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl vfile: Global ACLs disabled 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: Namespace : type=private, prefix=#EXPUNGED/, sep=, inbox=no, hidden=yes, list=no, subscriptions=no location=mdbox:/srv/storage1/vmail/company/628:MAILBOXDIR=expunged 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: fs: root=/srv/storage1/vmail/company/628, index=, indexpvt=, control=, inbox=, alt= 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl: initializing backend with data: vfile 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl: acl username = user(a)company.at 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl: owner = 1 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl vfile: Global ACLs disabled 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: Namespace : type=shared, prefix=#Users/%u/, sep=/, inbox=no, hidden=no, list=children, subscriptions=yes location=mdbox:/srv/storage1/vmail%h 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: shared: root=/var/run/dovecot, index=, indexpvt=, control=, inbox=, alt= 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl vfile: file /srv/storage1/vmail/company/628/mailboxes/dovecot-acl not found 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: Namespace : Using permissions from /srv/storage1/vmail/company/628: mode=0700 gid=default 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl vfile: file /srv/storage1/vmail/company/628/mailboxes/Drafts/dbox-Mails/dovecot-acl not found 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl vfile: file /srv/storage1/vmail/company/628/expunged/dovecot-acl not found 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: Namespace #EXPUNGED/: Using permissions from /srv/storage1/vmail/company/628: mode=0700 gid=default 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl vfile: file /srv/storage1/vmail/company/628/expunged/INBOX/dbox-Mails/dovecot-acl not found 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl vfile: file /srv/storage1/vmail/company/628/expunged/INBOX/test/dbox-Mails/dovecot-acl not found 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl vfile: reading file /srv/storage1/vmail/company/628/mailboxes/INBOX/dbox-Mails/dovecot-acl 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Logged out in=178 out=870 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Logged out in=315 out=27172 regards, -- Harald Leithner ITronic Wiedner Hauptstraße 120/5.1, 1050 Wien, Austria Tel: +43-1-545 0 604 Mobil: +43-699-123 78 4 78 Mail: leithner(a)itronic.at | itronic.at

Automatic purging of old email in all mailboxes
by Scott W. Sander 30 Aug '16

30 Aug '16

I am using a postfix + Dovecot server as a test mail server for which some applications in our test environment use as a target to deliver email so that our real endusers don't receive messages from our test servers. A few of the mailboxes in Dovecot receive hundreds of emails per day. I'd like to automatically remove all emails in all mailboxes and mailbox folders that were received more than 90 days prior to the received date. As I'm a novice Dovecot administrator, I'm not exactly sure what the best way to accomplish this is, but I've started looking at the "doveadm expunge" command. I figure I could create a cron job that calls this command with the -A switch and that has a search query that finds all emails older than 90 days. I'm aware that I can test my query by using the "doveadm search" command. The problem is that when I do any sort of search query with that command (e.g. "doveadm search -A NEW"), I receive the following error messages: Error: User listing returned failure doveadm: Error: Failed to iterate through some users I've searched for help with this error, but most of the guidance I'm seeing refers to making sure that dovecot-sql is configured correctly; however, I'm using "passwd-file" for the passdb and not a true database. Here is doveconf -n: ------- # 2.2.22 (fe789d2): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.13 (7b14904) # OS: Linux 4.4.0-34-generic x86_64 Ubuntu 16.04.1 LTS ext4 auth_mechanisms = plain login hostname = mail.domain.test info_log_path = /var/log/dovecot.log log_path = /var/log/dovecot.log mail_location = maildir:/var/mail/vhosts/%d/%n namespace inbox { inbox = yes location = mailbox "Deleted Items" { special_use = \Trash } mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox "Junk E-Mail" { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Items" { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = scheme=PLAIN username_format=%u /etc/dovecot/dovecot-users driver = passwd-file } protocols = " imap lmtp pop3" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } } service imap-login { inet_listener imaps { port = 993 ssl = yes } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service pop3-login { inet_listener pop3s { port = 995 ssl = yes } } ssl = required ssl_cert = </etc/ssl/certs/appserver4_combined.pem ssl_key = </etc/ssl/private/appserver4_key.pem userdb { args = uid=vmail gid=vmail home=/var/mail/vhosts/%d/%n driver = static } ------- Thank you in advance!

Sub addressing delimiters
by Kurt Fitzner 30 Aug '16

30 Aug '16

Hello, There is a disconnect between the way Postfix handles recipient_delimiter and the way Dovecot handles it. For Postfix, it is a set of delimiters that can each individually be used to separate the address from the . In Dovecot, having multiple characters in recipient_delimiters simply makes it a multi-character single delimiter. For my purposes, the Postfix method is much more versatile. Extra delimiters can be added without breaking the way users currently have delimiters. I am wondering what the odds are of reconciling the two approaches, hopefully in favour of the Postfix one. Failing a switch to the other behaviour, is it possible to add the Postfix method as an option? Would a patch for either of these be accepted? Thanks, Kurt Fitzner

Move dovecot between servers
by Gandalf Corvotempesta 30 Aug '16

30 Aug '16

Hi to all I have a very old dovecot server (1.2.15) with about 195GB used and 1081 email accounts. I have to move this server to another one with contextual dovecot upgrade. Anyone did this before? Any advice? Obviously, existing emails *must not* be downloaded twice by existing clients (outlook, thunderbird, ...) I have no access to customer's clients, only to my server.

sieve-filter with duplicate-extension
by hendrik＠luecke-tieke.de 26 Aug '16

26 Aug '16

Hi, i have imported a mailbox twice (accentially). Now i thought, it might be a valid approach to simply use a custom sieve rule to mark duplicates using the attached ruleset I ran sieve-filter like this: ~# sieve-filter -e -W -v -C -u userxyz(a)example.com /var/vmail/example.com/userxyz/sieve/duplicates.sieve 'INBOX' But sieve-filter complains like this: info: msgid=<1231321313212312312312(a)p3enginer2.emv2.com>: left message in mailbox 'INBOX'. info: message kept in source mailbox. info: filtering: [Sun, 1 May 2011 16:41:46 +0100; 101297 bytes] `Cipo & Baxx, Nike Golf, Strenesse, al...'. roundcube2: line 3: warning: duplicate test: duplicate checking not available in this context. info: msgid=<1123123123123123(a)p3enginer3.emv2.com>: left message in mailbox 'INBOX'. info: message kept in source mailbox. info: filtering: [Sun, 28 Oct 2012 11:32:56 +0100; 1416 bytes] `DenyHosts Report for example.com'. roundcube2: line 3: warning: duplicate test: duplicate checking not available in this context. Is there a way, to refilter an existing mailbox and applying the duplicate extension? Many thanks and best regards, Hendrik

lazy_expunge and public folder
by Arne Hoffmann 26 Aug '16

26 Aug '16

Hi all, I stumbled upon the lazy_expunge plugin and thought that it might be useful in some cases. It works fine if I delete mails from my inbox. But it doesn't do anything if I deleted mails from a public folder (and for the server I am currently working on the public folder is _the_ _main_ _feature_). Does lazy_expunge not work with public folders? Or am I using it wrong? root@imap01 [~]# doveconf -n # 2.2.24 (a82c823): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.13 (7b14904) # OS: Linux 3.16.0-4-amd64 x86_64 Debian 8.5 ext4 auth_debug = yes auth_debug_passwords = yes debug_log_path = /var/log/mail.debug disable_plaintext_auth = no doveadm_password = # hidden, use -P to show it doveadm_port = 22001 mail_debug = yes mail_location = maildir:/var/mail/vmail/%d/%n/Maildir:INBOX=/var/mail/vmail/%d/%n/Maildir mail_plugins = " listescape lazy_expunge notify replication" mail_privileged_group = vmail namespace { location = maildir:/var/mail/vmail/Öffentliche Ordner:INDEXPVT=~/Maildir/Öffentliche Ordner mailbox "Gelöschte Elemente" { auto = subscribe special_use = \Trash } mailbox MirrorServer-Projekt { auto = subscribe } prefix = Öffentliche Ordner/ separator = / subscriptions = no type = public } namespace { hidden = yes list = no location = maildir:~/Maildir/expunged prefix = .EXPUNGED/ separator = / } namespace inbox { inbox = yes location = prefix = separator = / type = private } passdb { args = /etc/dovecot/mysql.conf driver = sql } plugin { lazy_expunge = .EXPUNGED/ mail_replica = tcps:imap02.example.com } protocols = imap service aggregator { fifo_listener replication-notify-fifo { user = vmail } unix_listener replication-notify { user = vmail } } service doveadm { inet_listener { port = 22001 ssl = yes } } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { group = vmail mode = 0660 } } ssl = required ssl_ca = </etc/ssl/os/cert-sub-ca1-and-root-ca.pem ssl_cert = </etc/ssl/os/cert-imap01-example.com.pem ssl_client_ca_file = /etc/ssl/os/cert-all.pem ssl_client_cert = </etc/ssl/os/cert-imap01-example.com.pem ssl_client_key = </etc/ssl/os/key-imap01-example.com.pem ssl_key = </etc/ssl/os/key-imap01-example.com.pem ssl_require_crl = no userdb { args = /etc/dovecot/mysql.conf driver = sql } root@imap01 [~]#

Change dovecot hostname

Possible IMAP IDLE bug in Dovecot 2.2.18 and 2.2.25
by cleber-listas＠inetweb.com.br 24 Aug '16

24 Aug '16

Hello Guys, I guess that I found a bug in Dovecot 2.2.18 and 2.2.25 versions. The problem it's when I try to connect in a Dovecot used a proxy to another e-mail server (in our case it's a Smartermail Server) the DoveCot send a lot of IDLE commands to the destination server. With that, the LOG files grow and grow and grow :( I make a test with 1 connection only and if you see the log file in the same second the dovecot send 25, 40 IDLE commands. But, when I disconnect the client (outlook 2013) the dovecot continue to send the IDLE command for some seconds. If I try to connect directly to Smartermail with Outlook this don't occurrs.

If my understanding is correct, you should never ever ever ever ever ever ever send those sort of NDR's. Please google "backscatter".

antispam plugin pipe script seems not to be called when it "should be"
by Ben Johnson 23 Aug '16

23 Aug '16

Hello, (Full "doveconf -n" output is at the end of this message.) I'm attempting to recreate a "recipe" I had used successfully for quite some time (in Ubuntu 12.04 LTS), which allowed me to train SpamAssassin's Bayes database when someone dragged an email message from one sub-folder of the account to another. I later tried to re-implement it (in Ubuntu 14.04 LTS), and core-dumps resulted. I posted to this list about it several times, but nobody was ever able to help me solve the problem. I just tried the same (in Ubuntu 16.04 LTS), hoping that the source had evolved since then, and while I don't see a core-dump, the pipe script doesn't seem to be called. I've booby-trapped the pipe script with quite a bit of debugging output, which should be written to a file, but I don't see any indication that the pipe script is ever executed. When logged-in as an IMAP user, and I drag a message from the user's Inbox into the "Spam" folder, I do see the following activity in the syslog: Aug 18 22:12:15 example.com imap: antispam: mailbox_is_unsure(Junk): 0 Aug 18 22:12:15 example.com imap: antispam: mailbox_is_trash(INBOX): 0 Aug 18 22:12:15 example.com imap: antispam: mailbox_is_trash(Junk): 0 Aug 18 22:12:15 example.com imap: antispam: mail copy: from trash: 0, to trash: 0 Aug 18 22:12:15 example.com imap: antispam: mailbox_is_spam(INBOX): 0 Aug 18 22:12:15 example.com imap: antispam: mailbox_is_spam(Junk): 1 Aug 18 22:12:15 example.com imap: antispam: mailbox_is_unsure(INBOX): 0 Aug 18 22:12:15 example.com imap: antispam: mail copy: src spam: 0, dst spam: 1, src unsure: 0 Aug 18 22:12:15 example.com imap: antispam: running mailtrain backend program /bin/bash Aug 18 22:12:15 example.com imap: antispam: running mailtrain backend program /bin/bash Aug 18 22:12:15 example.com imap: antispam: running mailtrain backend program parameter 1 /usr/local/bin/sa-learn-pipe.sh Aug 18 22:12:15 example.com imap: antispam: running mailtrain backend program parameter 2 --spam But the piped message is never delivered to the target mailbox. The mail log at /var/log/mail.log does not register any activity when I move messages (and maybe that's expected).
