Trying to install Mailcrypt, receive completely blank emails
by sewing 22 Aug '19

22 Aug '19

Hi - perhaps someone can help me. Starting from a good and well-functioning mailserver setup, I have installed MailCrypt as per the instructions (I think) to have the per-user passworded keys setup. dovecot.conf /Added:/ mail_attribute_dict = file:%h/Maildir/dovecot-attributes mail_plugins = $mail_plugins mail_crypt dovecot-sql.conf.ext /commented this/ #password_query = SELECT email as user, password FROM virtual_users WHERE email='%u'; /Added this/ password_query = SELECT \ email as user, password, \ '%w' AS userdb_mail_crypt_private_password \ FROM virtual_users WHERE email='%u'; 90-plugin.conf /Updated this section/ plugin { mail_crypt_curve = secp521r1 mail_crypt_save_version = 2 /Have also tried all configurations this option set /#mail_crypt_require_encrypted_user_key = yes } /The user is in the mailserver SQL database:/ | user | password | userdb_mail_crypt_private_password | +----------------------+------------------------------------------------------------------------------------------------------------+------------------------------------+ | user@domain | 4t63ttt36tttttt3rt6r763r76t8998t858t4y48ht4huu4hti.76876t847t47yt4ty478yt4wgwygfwffweggggggggggwy8yey83//FElgiApZU. | %w /I have reissued the keys as other problem resolutions have instructed to do, and I can see the new keys are active./ doveadm -o plugin/mail_crypt_private_password=(same password as user@domain when created in SQL) mailbox cryptokey generate -u user@domain -UR /I have restarted dovecot and postfix each time./ /I then send an email either from the user@domain > user@domain OR otheruser@otherdomain > user@domain from Outlook. Authentication is fine (POP and SMTP). No errors appear in any logs - the logs show the mail as being received and I can see the mail in the user@domain /cur folder. If I try to Postcat any of these messages I get:/ postcat '1*********2.M**********3.(host),S=633,W=649:2,S' *** ENVELOPE RECORDS 1*********2.M*********3.(host),S=633,W=649:2,S *** message_size: YPTED postcat: fatal: invalid size record: YPTED??? */Within a minute or so I receive the email in the Outlook Inbox - except it is completely empty of anything. There is no TO / FROM/ SUBJECT / Body or even Routing information. See screencaps from Outlook/* <http://dovecot.2317879.n4.nabble.com/file/t5785/message_list_view.jpg> <http://dovecot.2317879.n4.nabble.com/file/t5785/empty-emails.jpg> /This happens with existing user mailboxes and new test mailboxes I create. If I deactivate Mailcrypt all mailboxes/user-accounts work fine. Any ideas??? I would like to get the working - thanks in advance for your expertise and time!/ Graham -- Sent from: http://dovecot.2317879.n4.nabble.com/

imapsieve suddenly not working anymore
by Thomas Stein 21 Aug '19

21 Aug '19

Hello one and all. Dovecot version 2.3.7.1 I've configured imapsieve like https://wiki.dovecot.org/HowTo/AntispamWithSieve a while a go and it worked for years now. Suddenly i noticed moving mails to the spamfolder does not trigger the report-spam.sieve script anymore. sieve-test gives: ~/.maildir/.Spam/cur $ sieve-test /usr/share/dovecot/sieve/report-spam.sieve 1542388745.M99384P16720.meine-oma.de\,S\=8173\,W\=8373\:2\,S -D sieve-test(himbeere): Debug: sieve: Pigeonhole version 0.5.7.1 (db5c74be) initializing sieve-test(himbeere): Debug: sieve: include: sieve_global is not set; it is currently not possible to include `:global' scripts. sieve-test(himbeere): Debug: sieve: Sieve imapsieve plugin for Pigeonhole version 0.5.7.1 (db5c74be) loaded sieve-test(himbeere): Debug: sieve: Sieve Extprograms plugin for Pigeonhole version 0.5.7.1 (db5c74be) loaded debug: file storage: Using Sieve script path: /usr/share/dovecot/sieve/report-spam.sieve. debug: file script: Opened script `report-spam' from `/usr/share/dovecot/sieve/report-spam.sieve'. debug: Script binary /usr/share/dovecot/sieve/report-spam.svbin successfully loaded. debug: binary save: not saving binary /usr/share/dovecot/sieve/report-spam.svbin, because it is already stored. report-spam: error: the imapsieve extension cannot be used outside IMAP. sieve-test(himbeere): Info: final result: failed; resolved with successful implicit keep ~/.maildir/.Spam/cur $ I'm not sure the "the imapsieve extension cannot be used outside IMAP" is the error already or thats only because the sieve-test script.

maildir very dirty sync option
by Yousif Alkhateeb 20 Aug '19

20 Aug '19

Hello , I have an active passive dovecot setup with glusterfs as a mail storage and using maildirs, we used to have a problem when users with large mailboxes sync their folders. This caused the load average to increase in the server , after a while we have enabled the very_dirty_sync option in dovecot , things got better and the problem disappeared but we need to know if there is any thing else that we need to do or know about the very_dirty_sync option that may cause future problems . Thanks in advance

Dovecot and Oauth
by Michael Hallager 20 Aug '19

20 Aug '19

Hi all, I am considering expanding a mail server to support Oauth with Google. I have read through the following: https://wiki.dovecot.org/PasswordDatabase/oauth2 however, it doesn't work and appears to me to be missing important information, the least of which is API authorisation. Searching with Google, I can't find any more information beyond what amounts to C&P'ing of the above link. Has anyone successfully deployed Oauth with Google and could they please send me their config files? Thanks, Michael

Dovecot and hard links?

I was looking at a mail folder and I noted that a file in the inbox had a total of 11 hard links to it: 👹 # exa -lH cur/1564249738.M167990P53982.mail.covisp.net,S=8572,W=8738:2,Sgl .rw------- 11 8.6k vpopmail 19 Jul 19:59 cur/1564249738.M167990P53982.mail.covisp.net,S=8572,W=8738:2,Sgl 👹 # find . -samefile cur/1564249738.M167990P53982.mail.covisp.net,S=8572,W=8738:2,Sgl [6:59] [/usr/local/virtual/kreme(a)kreme.com/Maildir] ./.Junk/cur/1564253637.M808919P50422.mail.covisp.net,S=8572,W=8738:2,bc ./.Junk/cur/1564253637.M808920P50422.mail.covisp.net,S=8572,W=8738:2,bc ./.Junk/cur/1564253723.M977674P50422.mail.covisp.net,S=8572,W=8738:2,bc ./.Junk/cur/1564253723.M977675P50422.mail.covisp.net,S=8572,W=8738:2,bc ./.Junk/cur/1564253723.M977676P50422.mail.covisp.net,S=8572,W=8738:2,bc ./.Junk/cur/1563587951.M591499P47868.mail.covisp.net,S=8572,W=8738:2, ./.Junk/cur/1564851795.M381461P10380.mail.covisp.net,S=8572,W=8738:2,bc ./.Junk/cur/1564851795.M381462P10380.mail.covisp.net,S=8572,W=8738:2,bc ./.Junk/cur/1564852369.M760020P10380.mail.covisp.net,S=8572,W=8738:2,bc ./.Trash/cur/1563587951.M591499P47868.mail.covisp.net,S=8572,W=8738:2,S ./cur/1564249738.M167990P53982.mail.covisp.net,S=8572,W=8738:2,Sgl A bit of background: a few weeks ago I had thousands of files in the mail store that had hundreds of links, and I got that all cleaned up through juggling some grep and awk to delete all but one of the linked files. I figured this was caused by something I’d done when I moved local users into being virtual users and eliminated pam authentication in favor of sql. But this gives me pause. I think it’s normal for a file in the INBOX that is marked as junk or as deleted to have a single hard link (or at least it is since the default was set to maildir_copy_with_hardlinks), but 11? And when do these hard links get cleaned off? If I delete the trashed and junked messages, when does dovecot go through and removed the linked files in the cur/ folder? (It’s not immediate, I trashed those copies in Junk and Trash and the original file is still in the cur folder) -- There is nothing so stupid that some person somewhere will not, with earnestness, say it.

Are you talking about the submission relay service or submission of outgoing messages from e.g. Sieve? The submission relay service. I like the idea of this service. Currently I did not activate the relay trust option, because I have no idea on how I could give permissions on the Postfix side. If Dovecot would send the certificate as reply to the smtpd_ask_ccert option, I could turn on XCLIENT in Dovecot and give permission based on the certificate fingerprint.

exim+dovecot+sieve issue
by JM 18 Aug '19

18 Aug '19

Hi, We have mail server in production, with Exim + Dovecot + Mailman + OpenLDAP + Roundcube webmail server. Openldap keeps mail accounts in db, exim uses lmtp transport to deliver messages to dovecot. Mailman is responsible for mailing lists, Roundcube webmail has managsieve module to create sieve filters. Exim router,transport for dovecot > localuser: > driver = accept > domains = +local_domains : +virt_domains > check_local_user > transport = dovecot_lmtp > cannot_route_message = Unknown account > no_more > dovecot_lmtp: > driver = lmtp > socket = /var/spool/dovecot/lmtp > batch_max = 500 > rcpt_include_affixes It worked perfectly, but after upgrade from Dovecot 2.2 to Dovecot 2.3 major version, I've found a lot of strange errors in exim panic.log > mail exim[7821] Failed to get user name for uid 1175 > mail exim[7880]: Failed to get user name for uid 1173 etc where uids are ldap accounts and recognized by system (id 1175 shows user's name and group) Even worse, some clients start to receive notify email with strange content, when sending email to mailing lists > user(a)domain.com > Delay reason: error in redirect data: malformed address: > someuser1(a)domain.com may not follow someuser2(a)domain.com in " > someuser3(a)domain.com ..some crap here.." , where someuser addresses are > not related to recipient address and unknown for sender. After some investigation,I've found out that dovecot's sieve produces these errors (I suspect sieve vacation, when user creates vacation via Roundcube webmail). If set "submission_host = exim ip" in dovecot.conf, exim doesn't produce errors in panic.log anymore, but clients still receive email with malformed address. Please help me to find the root of the problem (some broken sieve filter in user's maildir, misconfiguration or breaking changes in new Dovecot version?) Current software Gentoo with 4.14.90 kernel Dovecot-2.3.7.1 Exim-4.92.1 Mailman 2.1.29 Openldap-2.4.47 Roundcube-1.3.8 Dovecot.conf attached Regards, Juri

Dovecot not responding to external clients

Hi all I have Dovecot on my Linux-Mint workstation, running IMAP for the Thunderbird client thereon, but previously also for my phone and laptop clients as well. Since upgrading to Linux-Mint 19, however, although the Thunderbird client on the workstation works just fine, the other clients can't connect. I've disabled the firewall, and nmap shows the ports open, so it seems like some setting in the server.

Autoexpunge not working for Junk?
by Amir Caspi 14 Aug '19

14 Aug '19

Hi all, I set up dovecot a couple of months ago and am having trouble getting autoexpunge=30d to work on my Trash and Junk mailboxes. Not sure why not because I'm not getting error messages in my log. Running "doveadm search -u <user> mailbox Junk savedbefore 30d" shows me many messages (I've got messages back to mid-May, and a couple of other users have them back to early April, although if this setting were working, there should be nothing earlier than June 24). Running a manual doveadm expunge works fine... it's just autoexpunge that seems to not be running at all. I'm using sendmail as the MTA and procmail as the LDA, so dovecot is running purely for IMAP/POP service. Any help is much appreciated. Thanks! doveconf -n: # 2.2.36 (1f10bfa63): /etc/dovecot/dovecot.conf # OS: Linux 3.10.0-957.21.3.el7.x86_64 x86_64 CentOS Linux release 7.6.1810 (Core) # Hostname: REDACTED auth_username_format = %Ln first_valid_uid = 1000 mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u mailbox_list_index = yes mbox_write_locks = fcntl namespace compat1 { alias_for = hidden = yes list = no location = prefix = mail/ separator = / } namespace compat2 { alias_for = hidden = yes list = no location = prefix = ~/mail/ separator = / } namespace compat3 { alias_for = hidden = yes list = no location = prefix = ~%u/mail/ separator = / } namespace inbox { inbox = yes location = mailbox Archive { special_use = \Archive } mailbox "Deleted Messages" { autoexpunge = 30 days special_use = \Trash } mailbox Drafts { special_use = \Drafts } mailbox Junk { autoexpunge = 30 days special_use = \Junk } mailbox "Junk E-mail" { autoexpunge = 30 days special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Spam { autoexpunge = 30 days special_use = \Junk } mailbox Trash { autoexpunge = 30 days special_use = \Trash } prefix = separator = / } passdb { driver = pam } pop3_uidl_format = %08Xv%08Xu ssl_cert = # REDACTED ssl_cipher_list = # REDACTED ssl_dh_parameters_length = # REDACTED ssl_key = # hidden, use -P to show it ssl_prefer_server_ciphers = yes userdb { driver = passwd } --- Amir

segmentation fault in fs_list_get_path
by David M. Johnson 14 Aug '19

14 Aug '19

Hi, There seems to be a straightforward bug in src/lib-storage/list/mailbox-list-fs.c:79. set->index_dir is unchecked prior to dereferencing (unlike on line 126 in the same file, where it is properly checked).

auth module logging
by AP 14 Aug '19

14 Aug '19

Hi, As per my discussion with cmouse on irc, I'm currently just using dovecot for its auth mechanism, etc capabilities (alas, Exim does not support argon directly). Tis a fun little side project. :) I have the config pared down as far as I think is reasonable (see below) and all is working well except that dovecot is very silent. Errors hit the logs but I would appreciate seeing successful auths happen for the additional piece of mind. Cmouse and I couldn't find a way to do it on irc and it appears that the capability is missing. Successul /logins/ can be logged but auths, by themselves, cannot. I would appreciate if the ability was added. Dovecot 2.3.7.1 is in use. Thanks # Pigeonhole version 0.5.7.1 (db5c74be) # OS: Linux 5.2.4 x86_64 Debian 10.0 # Hostname: bob auth_mechanisms = plain login auth_verbose = yes auth_verbose_passwords = sha1:16 log_timestamp = "%Y-%m-%d %H:%M:%S %z " mail_log_prefix = "%{pid}<%{session}> %{service}(%{user}): " passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } service anvil { unix_listener anvil-auth-penalty { mode = 00 } } service auth-worker { user = $default_internal_user } service auth { unix_listener auth-client { group = Debian-exim mode = 0660 } } ssl = no userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } AP

Auth driver

(resending to the list; I apologize, I'm not using my usual email client) Hello, That's actually great news. The perspective of working in-tree didn't make me particularly happy. Could you point me to any documentation or examples? While I can find many plugins in the repo and around the Internet, I could find none which add authdb drivers. Best Regards, Riccardo P.

It's going to be, in concept, similar to the Lua and CheckPassword drivers, in that it allows an user program to carry out the authentication and user enumeration steps. If you do this, please make it as 3rd party repository. Dovecot auth supports plugins. Aki

ACL ignored for master users
by Philip Iezzi 14 Aug '19

14 Aug '19

Hi there! I can't get ACL working for master users. Login as master user works fine though, and I am able to access any mailbox using the auth_master_user_separator "*", tested e.g. via Python's imaplib: import imaplib imap = imaplib.IMAP4_SSL('imap.example.com') imap.login('foo(a)example.com*admin-acldemo', '**********') ('OK', [b'Logged in']) My /etc/dovecot/dovecot-acl looks like this: * user=admin lr bar(a)example.com user=admin-acldemo lr So, if I didn't misunderstand https://wiki.dovecot.org/Authentication/MasterUsers and https://wiki.dovecot.org/ACL documentation, this should only give "admin" master user access to all mailaccounts and limiting "admin-acldemo" master user to only a single mailaccount. That's what I would like to accomplish. But no matter what I put into dovecot-acl (it could even be empty), master users always have access to all existing mailaccounts. The whole dovecot-acl seems to be ignored and there are no logs pointing to any problem (syntax, access permissions) with that file. In mail.log I am getting a successful login message: dovecot: imap-login: Login: user=<foo(a)example.com>, method=PLAIN, ... So the login with "foo(a)example.com*admin-acldemo" seems to get resolved to a regular "foo(a)example.com" user login. My current setup (relevant config options): # 2.3.7.1 (0152c8b10): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.7.1 (db5c74be) # OS: Linux 4.15.18-18-pve x86_64 Debian 9.9 auth_master_user_separator = * mail_plugins = quota acl passdb { args = /etc/dovecot/passwd.masterusers driver = passwd-file master = yes pass = yes } plugin { acl = vfile:/etc/dovecot/dovecot-acl acl_user = %u master_user = %u } protocol lmtp { mail_plugins = quota acl sieve } protocol lda { mail_plugins = quota acl sieve } protocol imap { mail_plugins = quota acl imap_acl imap_quota } On ACL documentation it says: > Note that master users have their own ACLs. They're not the the mailbox owners, so by default they have no permissions to any of the mailboxes and on Authentication/MasterUsers documentation: > If ACL plugin is enabled, the Master user is still subject to ACLs just like any other user, which means that by default the master user has no access to any mailboxes of the user. So it must be somehow possible to limit master users to specific mailbox(es) via ACL. I could allow master users to be able to log in as themselves, by adding two passdb sections (one with `master = yes`, the other `master = no`), but then I see no way to do a user context switch (where ACLs would get respected...) after logging in with "admin". Any help greatly appreciated! Thanks in advance. Cheers, Philip

Dovecot - Microsoft Azure AD
by Lennart Boettcher 14 Aug '19

14 Aug '19

Hello, I am currently trying to connect my Dovecot mail server to Microsoft's Azure-AD and use it as password and user database. I am using version 2.3.7.1. Using the Azure-AD as passdb already works. In this context I noticed that the scope implementation is not yet merged. Since I haven't found any hints for an OAuth2 userdb implementation yet, I wanted to ask if there are any plans for an implementation. Greetings Lennart Boettcher

Solr, Dovecot & macOS / iOS
by James Brown 14 Aug '19

14 Aug '19

I’m thinking of getting Solr working with my Dovecot server. Server is new 6-core Mac Mini, mail store of over 1/2 TB. Mailboxes with 100s of thousands of messages. But I’m not sure if: a) it will make enough of a difference and b) does Mail.app and other mail clients on Macs or iOS devices perform searches on their local copy of mail or does it just send a search request to the server? I’m guessing the searches are done locally so no point in Solr? Does anyone know? Thanks, James.

Dovecot Sieve doesn't move spam to Junk folder in maildir
by Nagy Tibor 13 Aug '19

13 Aug '19

I have an *Ubuntu 16.04* mail server with postfix/spamassassin/*dovecot-2.2.2**2* with virtual mailboxes in maildir format. The whole process is working excellently since a year. Spams are marked with "*****SPAM*****" in subject and with "X-Spam-Flag: YES" in email header. I tried now to add sieve to dovecot to move the SPAM messages into the Junk folder without any success, I don't see any sign that sieve does something at all. The output of "dovecot -n": # 2.2.22 (fe789d2): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.13 (7b14904) # OS: Linux 4.4.0-72-generic x86_64 Ubuntu 16.04.2 LTS ext4 auth_mechanisms = cram-md5 auth_verbose = yes base_dir = /var/run/dovecot/ info_log_path = /var/log/dovecot.info log_path = /var/log/dovecot log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = maildir:/home/vmail/%d/%n managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext namespace { inbox = yes location = prefix = separator = / } passdb { args = /etc/dovecot/passwd driver = passwd-file } plugin { sieve = /etc/dovecot/sieve/default.sieve } protocols = imap pop3 service auth { executable = /usr/lib/dovecot/auth unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } user = root } service imap-login { chroot = login executable = /usr/lib/dovecot/imap-login inet_listener imap { port = 0 } user = dovecot } service imap { executable = /usr/lib/dovecot/imap } service pop3-login { chroot = login executable = /usr/lib/dovecot/pop3-login inet_listener pop3 { port = 0 } inet_listener pop3s { port = 0 } user = dovecot } service pop3 { executable = /usr/lib/dovecot/pop3 } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /etc/dovecot/users driver = passwd-file } valid_chroot_dirs = /var/spool/vmail protocol pop3 { pop3_uidl_format = %08Xu%08Xv } protocol lda { mail_plugins = " sieve" } I've added only plugin and protocol lda now. The content of the file default.sieve: require "fileinto"; if header :contains "X-Spam-Flag" "YES" { fileinto "Junk"; } The test SPAM message is marked as SPAM, but not moved to the folder Junk.
