Cannot subscribe to Public mailbox
by MI 04 Sep '16

04 Sep '16

I'm trying to set up a Public mailbox, but when I try to subscribe to it in Thunderbird, nothing happens: it doesn't appear as a folder, and when I go back to the Subscribe window, it is unchecked again. I use postfix local dlivery, which created a Maildir when a mail arrived for this mailbox: /home/others/sharedmail/Maildir/{cur,new,tmp} (sharedmail is a system user so that Postfix can deliver the mail; it doesn't have a login shell or a password) To make sure it is not a simple filesystem permissions problem, I did "chmod -R a+rwX Maildir/" This is my current config ( I tried to keep it short by leaving only what might be relevant ): # dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.9 ... mail_location = maildir:~/Maildir namespace { list = yes location = maildir:/home/others/sharedmail/Maildir prefix = Public. separator = . subscriptions = no type = public } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox ... ... } prefix = separator = . } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } userdb { driver = passwd } Also, I'm not sure about the difference between type=public and type=shared. But anyway, I tried both with the same result.

Alternate mail store of few users is disparaged unexpectedly
by Prakash Autade 02 Sep '16

02 Sep '16

Hello, We are using dovecot with mdbox and ALT store on S3(Simple Storage System). We export the mail_location=mdbox:/<user-mailstore>/mdbox:ALT=/altmailstore/<user-mailstore>/mdbox of user in extra parameters. Today, alternate mail store of few users is disparaged unexpectedly which resulted in mail loss. We are unable to trace out why and when the alternate store is disparaged. Our hypothesis is, the folder is removed during doveadm altmove. We want to prevent this in future. It will be great if someone helps to identify the root cause. Dovecot version: 2.2.19 # dovecot -n # 2.2.19: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-573.el6.x86_64 x86_64 CentOS Linux release 6.0 (Final) auth_mechanisms = plain login auth_verbose_passwords = plain disable_plaintext_auth = no mail_fsync = always mail_gid = 65111 mail_location = maildir:~/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = " quota" mail_uid = 65111 mdbox_rotate_interval = 1 days mdbox_rotate_size = 20 M mmap_disable = yes namespace inbox { inbox = yes location = mailbox Drafts { auto = create special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Items" { auto = create } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { auto = create special_use = \Trash } mailbox chat { auto = create } prefix = INBOX. separator = . type = private } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size } ssl_cert = </conf/server/server.crt ssl_key = </conf/server/server.key -- Sincerely, Prakash P.

Dovecot 2.2.25 fails on SSL
by Andreas M. Kirchwitz 02 Sep '16

02 Sep '16

Dear Dovecot developers! This problem already existed some years ago, has been fixed, and now it's there again in Dovecot 2.2.25 (2.2.24 was fine). I'm running CentOS 6 with a custom OpenSSL installation in /usr/local/ssl Therefore, Dovecot is configured like this: env SSL_CFLAGS="-I/usr/local/ssl/include" SSL_LIBS="-L/usr/local/ssl/lib -Wl,-R/usr/local/ssl/lib -lcrypto -lssl" ./configure --prefix=/usr/local/Dovecot-2.2.25 --with-ssl=openssl --with-ssldir=/usr/local/Dovecot-2.2.25/etc/dovecot/certs With "pkg-config", the same options for SSL are provided. "make" and "make install" run just fine, and the daemon starts without any errors. However, if a user connects on port 993 (IMAPS), Dovecot logs this failure message to syslog: Jul 4 01:08:43 myhost dovecot: ssl-params: Fatal: Couldn't load required plugin /usr/local/Dovecot-2.2.25/lib/dovecot/libssl_iostream_openssl.so: dlopen() failed: libcrypto.so.1.0.0: cannot open shared object file: No such file or directory Jul 4 01:08:43 myhost dovecot: ssl-params: Error: child process failed with status 22784 ldd /usr/local/Dovecot-2.2.25/lib/dovecot/libssl_iostream_openssl.so linux-gate.so.1 => (0x00e8c000) libcrypto.so.1.0.0 => not found libssl.so.1.0.0 => not found librt.so.1 => /lib/librt.so.1 (0x00be4000) libc.so.6 => /lib/libc.so.6 (0x001a6000) libpthread.so.0 => /lib/libpthread.so.0 (0x003e4000) /lib/ld-linux.so.2 (0x007e7000) ldd /usr/local/Dovecot-2.2.25/lib/dovecot/libdcrypt_openssl.so linux-gate.so.1 => (0x00dca000) libcrypto.so.1.0.0 => not found libssl.so.1.0.0 => not found librt.so.1 => /lib/librt.so.1 (0x00a7a000) libc.so.6 => /lib/libc.so.6 (0x00160000) libpthread.so.0 => /lib/libpthread.so.0 (0x0072f000) /lib/ld-linux.so.2 (0x00560000) When comparing to Dovecot 2.2.24: ldd /usr/local/Dovecot-2.2.24/lib/dovecot/libssl_iostream_openssl.so linux-gate.so.1 => (0x0073d000) libcrypto.so.1.0.0 => /usr/local/ssl/lib/libcrypto.so.1.0.0 (0x00b04000) libssl.so.1.0.0 => /usr/local/ssl/lib/libssl.so.1.0.0 (0x0044a000) librt.so.1 => /lib/librt.so.1 (0x00a60000) libc.so.6 => /lib/libc.so.6 (0x001e5000) libdl.so.2 => /lib/libdl.so.2 (0x003a9000) libpthread.so.0 => /lib/libpthread.so.0 (0x009d0000) /lib/ld-linux.so.2 (0x00d77000) There's no libdcrypt_openssl.so in Dovecot 2.2.24, so I guess with the newly introduced dcrypt stuff something with SSL went wrong. Would be great if that could be fixed so that SSL works again. Thanks a lot in advance ... Andreas

Force SSL/TLS and client certificate checking only for connections from Internet
by Konstantin Khomoutov 02 Sep '16

02 Sep '16

(Please CC me if possible.) I have Dovecot 2.2.13 (shipped with Debian 8 "Jessie") serving IMAP for a small organization. It's connected both to the Internet and to that organization LAN. I'd like to have Dovecot has rather tight security requirements for connections made from the Internet and reasonably laxed requirements for the LAN clients. Due to Dovecot authenticating users against a LDAP database which is also used for logging into the users' machines, we have to use somewhat weak passwords (randomly generated but short) for most users. Because of this I want to: * Mandate the usage of TLS for the connections made from Internet; * Require the clients to present their SSL certificates, and * Verify the validity of these certificates. The certificates are issued by our own CA, so it's not a problem to verify them. The first iteration was to set ssl = required and disable_plaintext_auth = yes which I then overrode with a "remote" section for LAN connections: remote 192.168.0.0/16 { disable_plaintext_auth = no ssl = yes } The next iteration was to actually enable verification of the client certificates. I have set the "ssl_ca" variable appropriately, then ssl_require_crl = yes ssl_verify_client_cert = yes and auth_ssl_require_client_cert = yes Then I went on and attempted to override the latter two settings for the LAN clients by appending them to my special "remote" section to it read: remote 192.168.0.0/16 { disable_plaintext_auth = no ssl = yes ssl_verify_client_cert = no auth_ssl_require_client_cert = no } But after restart Dovecot complained that I cannot use the "auth_ssl_require_client_cert" setting in a "remote" section. I have removed it in the hope that still having ssl_verify_client_cert = no there would inhibit SSL certificate checks for the LAN clients but apparently it did not. So, to recap: * I need to have tight TLS settings for the clients connecting from the Internet: - TLS is required; - The client must present a valid certificate (issued by a CA we control). * LAN clients should use relaxed security settings: TLS is okay but that's all. How do I go about setting this? (On a side note, I can supposedly get away installing stunnel and making it proxy IMAP and IMAPS connections to Dovecot -- at least from the documentation, it appears stunnel supports IMAP+STARTTLS, -- but I would rather have all this handled solely by Dovecot.)

Debian Jessie comes with systemd so you really should not use initscript anymore but switch to systemd for starting dovecot. There is systemd service description file available for you in case your vendor does not provide it in the package: https://github.com/dovecot/core/blob/master/dovecot.service.in Sami

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
by Scott W. Sander 25 Aug '16

25 Aug '16

I have noticed that the name of my private server running dovecot appears in email headers rather than the public-friendly name of my server. Is there a method to specify an alternate server name for the dovecot server to use for itself in the dovecot configuration files? I performed a few Google searches and was not able to find the answer to my question. ------- user@server1:~$ dovecot --version 2.2.9 user@server1:~$ dovecot -n # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux 3.16.0-77-generic x86_64 Ubuntu 14.04.4 LTS ext4 auth_mechanisms = plain login 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 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 { 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/server1_combined.pem ssl_key = </etc/ssl/private/server1_key.pem userdb { args = uid=vmail gid=vmail home=/var/mail/vhosts/%d/%n driver = static }

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. Bellow the LOG FILE: 16:08:08 [192.168.202.11][21425199] connected at 22/08/2016 16:08:08 16:08:08 [192.168.202.11][21425199] command: C CAPABILITY 16:08:09 [192.168.202.11][21425199] command: L LOGIN

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.

Postfix uses the filename you provide as name for the db file, so running it against symlinks does follow the symlink, but it uses the symlink name as what it uses to create the .db file. You can test this by creating file and doing symlink for it and running postmap against the symlink. You'll see that it will create symlink-name.db file instead of file.db. Aki Tuomi Dovecot oy

Oh yeah, right, LMTP. I don't run LMTP myself, but I suspect the hostname is mapped from the IP of the LMTP listening interface (using /etc/hosts or DNS). Maybe you can change the IP of your listening interface to match mail.domain.test and firewall it off if that IP is public facing. >From reading the code, I can't quite grok how LMTP derives the host label, but as a last resort, you can patch at src/lmtp/commands.c in client_get_added_headers().

specifying elliptic curve
by İhsan Doğan 23 Aug '16

23 Aug '16

Hi, I've noticed that Dovecot is using per default the elliptic curve sect571r1. Because not all clients might support sect571r1, I would like to set the elliptic curve manually. Is that possible? -Ihsan -- ihsan(a)dogan.ch http://blog.dogan.ch/

a question about certificates from letsencrypt
by Andreas Meyer 22 Aug '16

22 Aug '16

Hello! Certificates from letsencrypt are renewed every three months. Does that mean a MUA has to accept the renewed certificates manually everytime it is renewed? Sorry if this is OT! Greetings Andreas

Crash on opening mailbox
by Ladislav Laska 22 Aug '16

22 Aug '16

Hi! I'm currently experiencing a crash of dovecot 2.2.25 on Gentoo, upon opening mailbox. The crash only triggers on opening inbox, other mailboxes seem to work fine. It happens every time, and can be reproduced on request. I also briefly tried 2.2.19, and it behaves the same. The bug seems to be triggered by some mail, as I encountered it previously and fixed by removing some spam. I guess it might be malformed header of some kind. I can open the mailbox locally using mutt, but fail to do so remotely (using mutt or K-9 mail on android). Unforunately, I haven't been able to isolate the specific mail, as when I create a new mailbox, dovecot refuses to open it: [CANNOT] Mailbox isn't a valid mbox file (0.000 + 0.000 secs). I'm not really sure what's going on and will investigate further once I find some time to do so. I also experienced a similar problem on opening a specific mail, but it's much harder to reproduce and I currently don't have an example. The crash looks very similar, and only happens on first attempt to open a specific mail, it always works later on. I'm attaching a stack trace and dovecot -n. I'm also willing to send the binary and core dump, but not publicly, as I'm not eager to share whatever's inside with the whole world. Other than what I mentioned, I'm running pretty standard setup, with postfix on Gentoo x86_64, ext4 fs, quota and disk space is plentiful. The delivery agent is dovecot itself, in postfix/main.cf I have: mailbox_command = /usr/libexec/dovecot/deliver I'm using sieve script to file my mail, but the problem manifested even before when I was still using procmail to deliver my mail (I migrated because I had doubts about procmail and dovecot lock cooperation) I'll keep my mailbox corrupted for a few more days, and access the mail only locally, hoping to test a potential fix. Let me know if you need any more info/experimentation. Also, if you know a good way to find the mail that causes the trouble out of the core, let me know, I'd be glad to forward it for testing. Thanks and I hope we can find (and fix) the problem! -- S pozdravem Ladislav Láska <laska(a)kam.mff.cuni.cz> Katedra Aplikované Matematiky, MFF UK tel.: +420 739 464 167

LMTP doing passdb queries ?
by Peter Mogensen 22 Aug '16

22 Aug '16

Hi, I can see dovecot is doing a passdb query when handling the LMTP RCPT command. That's kinda unexpected for me. I would have thought it only did a userdb lookup. I have disabled lmtp_proxy to be sure it didn't do a passdb lookup to check the proxy field. Is this expected? Doesn't the LDA only do userdb lookups? /Peter

Catch-all with LMTP and Postfix
by Michael Starks 22 Aug '16

22 Aug '16

Hidy-ho, I'm having a difficult time getting catch-all working when using Dovecot LMTP. I would like *(a)example.com (everything) to go to virtual(a)example.com, where virtual is a valid virtual user. It seems that things are getting as far as LMTP, but then the mail gets bounced.

Field Return-Path contains twice the domain
by Quaquaraquà 22 Aug '16

22 Aug '16

Dear exim & dovecot users, posting on both mailing lists as I am not sure who has the ultimate responsability for this field. I am trying to set up a mail server for multiple domains in my VPS. So I managed to set up the authentication through a dovecot authenticator, which relies to a sqlite database. I would like that, from the database perspective, a query has, as input parameters, both the username and the domain to check the password. For this purpose, I am requesting that the SMTP account is in the full form username(a)domain.com. When forwarded to the dovecot authenticator, I can extract the user with %n and %d. This works, but it has a utter drawback: emails are sent repeating twice the domain in the Return-Path field, e.g. : Return-Path: <"user(a)domain.net"@domain.net> Subject: Re: Hello To: nuquaquaraqua(a)gmail.com From: user <user(a)domain.net> How do I properly fix the field Return-Path now? dovecot --version: 2.2.25 (7be1766) Exim version 4.87 #1 built 28-Jul-2016 18:38:04 Kind regards, Quaquaraqua

Here's the the sequence of commands that I'm using: # su vmail $ echo 'This is a test message.' > /tmp/test.txt $ stat /tmp/test.txt File: '/tmp/test.txt' Size: 24 Blocks: 8 IO Block: 4096 regular file Device: fd01h/64769d Inode: 783925 Links: 2 Access: (0664/-rw-rw-r--) Uid: ( 5000/ vmail) Gid: ( 5000/ vmail) Access: 2016-08-18 20:49:38.419011552 -0400 Modify: 2016-08-18 20:49:07.178995015 -0400 Change: 2016-08-18 20:49:38.191011425 -0400 Birth: - $ /usr/lib/dovecot/dovecot-lda -d "test(a)example.com" -p "/tmp/test.txt" When I do this, the destination mailbox acts like there's a new message (I'm using Thunderbird, and the mailbox is highlighted in blue and bolded, which is the "new mail" behavior in this client). But when I "check my inbox", i.e., click on the Inbox, I don't see the new message. With regard to the filesystem, the message is present and contains the intended contents. Here's the "stat" output: $ stat /var/vmail/example.com/ben/Maildir/cur/1471567777.M685753P32257.example.com,S=24:2, File: '/var/vmail/example.com/ben/Maildir/cur/1471567777.M685753P32257.example.com,S=24:2,' Size: 24 Blocks: 8 IO Block: 4096 regular file Device: fd01h/64769d Inode: 783925 Links: 2 Access: (0664/-rw-rw-r--) Uid: ( 5000/ vmail) Gid: ( 5000/ vmail) Access: 2016-08-18 20:51:05.647059340 -0400 Modify: 2016-08-18 20:50:58.543055378 -0400 Change: 2016-08-18 20:50:58.543055378 -0400 Birth: - Might anyone know why I'm not "seeing" this message in my IMAP client? Interestingly, I tried another IMAP client (Blue Mail for Android), and I can actually see the messages there, but they appear in the Inbox as: (No subject) <Empty Message> When I click on the messages, Blue Mail simply displays "No text", without the quotes. Surely, I'm overlooking something simple...

Hello everyone, I face the following challenge: - dovecot 2.2.13 - userdb: passwd-file - quota enabled: -- default 1GB -- changed for some users thru users file: user@domain:passwd::::::userdb_quota_rule=*:storage=15M - when sending a message to this user while near quota, warnings are correctly triggered => *OK* - when sending a message to this user while over quota, message is refused => *OK* - when checking quota from mail client (eg Thunderbird 45.2), reported quota is.. 1GB => *NOK* - some config: mail_plugins = quota notify acl plugin { acl_shared_dict = file:/sd/MAIL_IMAP_POP/%d/shared-mailboxes quota = maildir:User quota:ns= quota_exceeded_message = Storage quota for this account has been exceeded, please try again later. quota_rule = *:storage=1G quota_rule2 = Trash:storage=+10%% quota_rule3 = Spam:storage=+20%% quota_status_nouser = DUNNO quota_status_overquota = 552 5.2.2 Mailbox is full quota_status_success = DUNNO quota_warning = storage=90%% quota-warning 90 %u %d quota_warning2 = storage=75%% quota-warning 75 %u %d } protocol imap { mail_plugins = quota notify acl imap_quota imap_acl service replication-notify-fifo { name = aggregator } service anvil-auth-penalty { name = anvil } service auth-worker { name = auth-worker } service auth-client { name = auth } service config { name = config } service dict { name = dict } service login/proxy-notify { name = director } service dns-client { name = dns_client } service doveadm-server { name = doveadm } service imap { name = imap-login } service imap-urlauth { name = imap-urlauth-login } service imap-urlauth-worker { name = imap-urlauth-worker } service token-login/imap-urlauth { name = imap-urlauth } service login/imap { name = imap } service indexer-worker { name = indexer-worker } service indexer { name = indexer } service ipc { name = ipc } service lmtp { name = lmtp } service log-errors { name = log } service pop3 { name = pop3-login } service login/pop3 { name = pop3 } service replicator-doveadm { name = replicator } service login/ssl-params { name = ssl-params } service stats-mail { name = stats } } - 90-quota: passdb { driver = passwd-file args = scheme=CRYPT username_format=%u /etc/dovecot/users } userdb { driver = passwd-file args = username_format=%u /etc/dovecot/users # Default fields that can be overridden by passwd-file #default_fields = quota_rule=*:storage=1G # Override fields from passwd-file #override_fields = home=/home/virtual/%u } Any idea? Already spent hours on this. Thank you in advance for the help. Cheers A.
