Dovecot not connecting to OpenLDAP
by Elias Falconi 16 May '19

16 May '19

Hi, We recently shutdown our old LDAP server and repointed our mail server (dovecot + postfix) to our new LDAP server and ever since we've been unable to fetch mail. Mail is getting delivered, but we just can't pop it. We're using Ubuntu 16.04, btw. We keep on getting the following error messages in /var/log/dovecote: 2019-05-15 16:27:43 auth: Error: LDAP /etc/dovecot/dovecot-ldap.conf.ext: ldap_start_tls_s() failed: Can't contact LDAP server 2019-05-15 16:39:36 auth: Error: LDAP /etc/dovecot/dovecot-ldap.conf.ext: ldap_start_tls_s() failed: Connect error 2019-05-15 16:39:43 auth: Error: LDAP /etc/dovecot/dovecot-ldap.conf.ext: ldap_start_tls_s() failed: Local error However, our server is finding our LDAP users and postfix doesn't seem to have a problem, just Dovecot. Also, when we try to connect via Dovecot, we get the following message: -ERR [SYS/TEMP] Temporary authentication failure. [mail:2019-05-15 21:40:06] Our /etc/dovecot/dovecot.conf contains the following: ## Dovecot configuration file # If you're in a hurry, see http://wiki2.dovecot.org/QuickConfiguration # "doveconf -n" command gives a clean output of the changed settings.

In that case you'll # also have to include user_attrs in pass_attrs field prefixed with "userdb_" # string. For example: #pass_attrs = uid=user,userPassword=password,\ # homeDirectory=userdb_home,uidNumber=userdb_uid,gidNumber=userdb_gid # Filter for password lookups pass_filter = (&(objectClass=posixAccount)(uid=%u)) # Attributes and filter to get a list of all users #iterate_attrs = uid=user #iterate_filter = (objectClass=posixAccount) # Default password scheme. "{scheme}" before password overrides this. # List of supported schemes is in: http://wiki2.dovecot.org/Authentication #default_pass_scheme = CRYPT What do you suppose could be the problem?

Setting up individual encrypted user keys using mail-crypt-plugin
by emordin 16 May '19

16 May '19

Hi, I have setup up a simple mail server using the ISPMail tutorial and I'm trying to learn how to create email encryption at rest. I'm having a tough time understanding how to set this up... So say a user logins thru roundcube and they type in their password...so the password authenticates to the mysql database which is storing their encrypted private key?? And once they access that private key, how do they use that private key to unencrypt their mailbox? I'm a super noob at this, and I may be off, but I don't know where to start when it comes to setting this up... if I'm way off could you just recommend some tutorials or other basics I should learn first before moving on to setting this up?

Mutual auth and MS Outlook
by dovecot＠scottsavarese.com 16 May '19

16 May '19

I am trying to get Dovecot IMAP and Outlook to talk to each other with SSL and client certificates enabled. In Dovecot, I have the following options enabled: ssl_ca = ... ssl_verify_client_cert = yes auth_ssl_require_client_cert = yes auth_ssl_username_from_cert = yes when I try to connect with Outlook, I get: May 12 08:07:50 mail dovecot: imap-login: Disconnected (client didn't send a cert): user=<>, method=PLAIN, rip=192.168.1.245, lip=192.168.2.5, TLS: Disconnected, session=<is7gpa+Im97AqAH1> But when I use openssl directly with the same certificates it seems to pass the certificate in just fine. Does anybody have any ideas? Thanks in advance.

Hi Tobi, This looks like you haven’t included the libmaxmind libraries before running configure. GeoIP support is only compiled in if it finds the right libs.

LDA-based vacation responses bouncing
by micah anderson 14 May '19

14 May '19

I've got dovecot vacataion auto-responses working via sieve, but when the responses are sent, they are sent as if they are to be locally delivered, which causes them to bounce for domains that I am not local for. How can I get dovecot's sieve vacation response to check the domain is local or not? Here is an example of what happens: The LDA notices it needs to send a vacation response: 2019-05-14T10:50:47.827466-07:00 brant dovecot: lda(user(a)example.org)<14817><xL6LL/f/2lzhOQAAh856Uw>: sieve: msgid=<20190514135045.012486@localhost>: sent vacation response to <someone(a)somewhere.org> but that response was sent via the postfix pipe through the dovecot lda transport... because that is local, and the domain it is sending to is not local, it bounces: 2019-05-14T10:50:47.923333-07:00 brant postfix/pipe[14821]: C998381539: to=<someone(a)somewhere.org>, relay=dovecot, delay=0.11, delays=0.04/0.01/0/0.06, dsn=5.1.1, status=bounced (user unknown) Postfix is set to do this: dovecot unix - n n - - pipe flags=DRhu user=mail argv=/usr/bin/spamc --connect-retries=1 -H -d 10.0.1.92 -s 10240000 -t 100 -u ${recipient} -e /usr/lib/dovecot/dovecot-lda -f ${sender} -d ${recipient} require ["fileinto", "vacation"]; vacation :days 2 :subject "Helllo" "Hi"; Here is my doveconf -n: # 2.3.4.1 (f79e8e7e4): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.4 () # OS: Linux 4.9.0-8-amd64 x86_64 Debian 9.8 auth_worker_max_count = 120 default_client_limit = 6144 default_process_limit = 256 default_vsz_limit = 512 M dict { expire = mysql:/etc/dovecot/dovecot-dict-sql.conf quota = mysql:/etc/dovecot/dovecot-dict-sql.conf } disable_plaintext_auth = no first_valid_gid = 8 first_valid_uid = 8 last_valid_gid = 8 last_valid_uid = 8 listen = * login_greeting = howdy, ready. login_log_format_elements = user=<%u> method=%m rip=%r lip=%l mpid=%e %c %k mail_location = mdbox:~/mdbox mail_plugins = expire quota zlib maildir_very_dirty_syncs = yes namespace { inbox = yes location = prefix = separator = . } namespace { alias_for = hidden = yes inbox = no list = no location = prefix = INBOX. separator = . } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { expire = Trash expire2 = Trash/* expire3 = Spam expire_dict = proxy::expire quota = dict:Your mail quota::proxy::quota quota_rule = *:bytes=100663296 quota_rule2 = Trash:bytes=+20%% quota_rule3 = Spam:bytes=+10%% quota_rule4 = INBOX.Trash:bytes=+20%% quota_rule5 = INBOX.Spam:bytes=+10%% quota_rule6 = INBOX.restored_from_backups:bytes=+500%% sieve = ~/.dovecot.sieve sieve_after = /var/lib/dovecot/sieve/after.sieve sieve_before = /var/lib/dovecot/sieve/default.sieve sieve_dir = ~/sieve zlib_save = gz zlib_save_level = 6 } protocols = " imap pop3" service anvil { unix_listener anvil { group = dovecot mode = 0660 user = root } } service auth { client_limit = 6144 unix_listener auth-userdb { group = mail mode = 0600 user = mail } } service dict { unix_listener dict { group = mail mode = 0600 user = mail } } service imap-login { process_min_avail = 10 service_count = 0 vsz_limit = 512 M } service imap-postlogin { executable = script-login /usr/local/sbin/postlogin_imap } service imap { executable = imap imap-postlogin process_limit = 6144 } service pop3-login { process_min_avail = 10 service_count = 0 vsz_limit = 512 M } service pop3-postlogin { executable = script-login /usr/local/sbin/postlogin_pop } service pop3 { executable = pop3 pop3-postlogin } service stats { unix_listener stats-writer { group = mail mode = 0660 } } ssl_cert = </etc/certs/wildcard/cert.pem ssl_cipher_list = ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-DSS-AES128-GCM-SHA256:kEDH+AESGCM:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-DSS-AES128-SHA256:DHE-RSA-AES256-SHA256:DHE-DSS-AES256-SHA:DHE-RSA-AES256-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:AES:CAMELLIA:DES-CBC3-SHA:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!PSK:!aECDH:!EDH-DSS-DES-CBC3-SHA:!EDH-RSA-DES-CBC3-SHA:!KRB5-DES-CBC3-SHA ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it ssl_prefer_server_ciphers = yes userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } verbose_proctitle = yes verbose_ssl = yes protocol lda { mail_plugins = expire quota trees zlib sieve plugin { quota_exceeded_message = Sorry, your message cannot be delivered to that person because their mailbox is full.

Graceful dovecot reload for LE certificate renewals
by Sidsel Jensen 14 May '19

14 May '19

Hi Dovecot-gurus With the introduction of LE certificates the certificate renewal cycle is a lot faster, unfortunately even a "dovecot reload" cuts the existing connections when doing the cert updates, which is quite frustrating - and yes most clients automatically reconnect but still... Is any work going into implementing a more “graceful reload” for dovecot like the one for nginx where existing connections are preserved with the old cert and new connections get the new cert? Kind Regards, Sidsel Jensen Systems Engineer @ One.com <http://one.com/>

weakforced and GeoIP lookups
by Tobi 14 May '19

14 May '19

Hi list hope it's okay to ask weakforced questions here as well, but I could not find a dedicated mailinglist for wforce. I want to enable GeoIP lookups in my wforce daemon. In a first step I installed luarocks and lua-compat53 to install mmdblua module. Then I added newGeoIP2DB("country", "/usr/local/share/GeoIP/GeoLite2-Country.mmdb") local mygeodb = getGeoIP2DB("country") if(mygeodb:lookupCountry(lt.remote) == 'XX') then return -1, "country blocked", "country blocked", { country="XX" } end to wforce.conf and tried to restart wforce but that ends up in a > Fatal Lua error: [string "chunk"]:28: attempt to call global > 'newGeoIP2DB' (a nil value) Any ideas what I could be missing here?

Is it possible to (re)direct only 1 imap user to the new server
by Marc Roos 14 May '19

14 May '19

I haven't used dovecot proxy or director. If I have a setup where all my users are connecting to HOSTNAMEOLD, is it possible to have 1 imap user that is connecting to HOSTNAMEOLD directed/forwarded to HOSTNAMENEW? Without changing my dns settings and preferably without creating any new servers. I think I can route one users mail to HOSTNAMENEW with sendmail ldap routing. So the only thing I need to be able to do is have the incoming imap requests on HOSTNAMEOLD been handled by HOSTNAMENEW.

email notification regression between 2.2 and 2.3

Hi, Hello. For the last year, each time i've tried updating dovecot from 2.2.x to 2.3.x, I had to rollback because of the following problem: Users don't "see" new emails arriving in subdirs. To be specific * we mostly use/tested thunderbird client * we use maildrop for delivery * this is using imap, not pop3 * when a new email arrives, thunderbird renders the dir name in blue and appends a "(1)" (or more..). That's what we call 'see' * this happens only on 'subdirs', not the main directory. * the server is a typical linux amd64, using the gentoo distribution More testing shows that * if we switch delivery to dovecot-lda, it works ok. But we can't commit that change, or at least not now/easily. Our users heavily use .mailfilter * if the user is currently viewing the subdir, then email notification is working * better : if the user went on the subdir and then in another dir, it keeps on working. It seems we need to 'open' it at least once for notification to work * "maildir_very_dirty_syncs = no" doesn't help (we had =yes) * "mailbox_list_index = no" doesn't help * i can confirm inotify was detected/used in autoconf when installed (anyway it works well with 2.2) I'm always on freenode (orzel). I'll be in #dovecot the next days at least. greetings, -- Thomas Capricelli

Userdb userdb_mail=, error Mailbox list driver maildir++: maildir_name not supported by this driver
by Marc Roos 14 May '19

14 May '19

I have this default configuration [0], when use the userdb_mail to point to the mdbox location, the inbox subfolders show differently in a firebird client. So I decided to copy the whole default mail_location into the userdb_mail configuration [2]. But then I get errors [3]. Should I change the namespace configuration here, how?

dovecot 2.2.36 and wforce
by Tobi 13 May '19

13 May '19

Hi list I'm trying to setup dovecot 2.2.36 on a Centos6 to communicate with a wforce daemon on the remote side. wforce is latest released from git repo. Daemon part is working and I can successfully send queries from remote systems to wforce via curl For dovecot I configured in /etc/dovecot/conf.d/95-wforce.conf > auth_policy_server_url = http://REMOTE_IP:8084/ > auth_policy_hash_nonce = my_random > auth_policy_server_api_header = Authorization: Basic <BASE64 of wforce:my_password> > auth_policy_request_attributes = login=%{requested_username} pwhash=%{hashed_password} remote=%{rip} device_id=%{client_id} protocol=%s restarted dovecot without errors, but upon testing via imap I cannot see just one single tcp paket leaving direction REMOTE_IP on port 8084. It looks like auth policy in not involved at all. Thanks for any idea tobi

IMAPSieve message marked as HAM should go through full sieve script of user
by Matthias Fechner 10 May '19

10 May '19

Dear all, I use the IMAPSieve implementation described here: https://wiki.dovecot.org/HowTo/AntispamWithSieve It is working really great! Thanks a lot for this. The problem I have now is: A message was by accident marked by rspamd as spam, so a false-positive and is moved to the Junk folder. If I click in my email program now on `Not Spam` it is learn as HAM but moved to the INBOX. I would like that the email is not moved to INBOX but it should be moved through the sieve script of the user again, as it is a new email. Currently I have to mark all false-positives as not spam and have then to manually move it to the correct subfolder which is a bit annoying. Is this possible? Thanks a lot! -- Gruß Matthias

doveadm sync issues (revised)
by Sven Strickroth 10 May '19

10 May '19

Hi, I'm experiencing serious issues using doveadm sync; mails are not replicating and/or mails are duplicating. I wanted to use this for migrating external mailboxes to my server (in order to overcome the time when some servers/clients still use the old server and some already my server, as described on <https://wiki2.dovecot.org/Tools/Doveadm/Sync>). Finally I was able to reproduce this with the 2.3 branch (cf. <https://dovecot.org/pipermail/dovecot/2019-April/115600.html>). I'm sorry that I can only test the version 2.3.4.1, but according to the changelog I think this is still an issue with the latest version. I tried to find a few steps in order to replicate this easily: For testing purposes I simulate both the remote and local server on my Dovecot instance. I created remote(a)DOMAIN.TLD and local(a)DOMAIN.TLD accounts and both use mdbox and are empty. First, send two mails to remote(a)DOMAIL.TLD (Subjects: Test1 and Test2). Start backup remote IMAP account (remote(a)DOMAIN.TLD) to local account (local(a)DOMAIN.TLD) $ doveadm -o imapc_user="remote(a)DOMAIN.TLD" -o imapc_password="PW" -o imapc_host="localhost" backup -R -u local(a)DOMAIN.TLD imapc: Both mailboxes are in sync now (containing Test1 und Test2). Now send two messages to remote(a)DOMAIN.TLD (Subjects Test3 and Test4) and two messages to local(a)DOMAIN.TLD (Subjects Test5 and Test6). Run sync: $ doveadm -o imapc_user="remote(a)DOMAIN.TLD" -o imapc_password="PW" -o imapc_host="localhost" sync -R -u local(a)DOMAIN.TLD imapc: See that syncing fails: remote(a)DOMAIN.TLD contains: Test1,2,3,4,5,6 (as expected) local(a)DOMAIN.TLD contains: Test1,2,5,6,4 (Test3 is missing here) When not using the "-R" parameter it seems to work. Running sync again: $ doveadm -o imapc_user="remote(a)DOMAIN.TLD" -o imapc_password="PW" -o imapc_host="localhost" sync -R -u local(a)DOMAIN.TLD imapc: causes messages to duplicate: remote(a)DOMAIN.TLD contains: Test1,2,6,5,4,3,5,6,4,6,5,4,3,5,6 local(a)DOMAIN.TLD contains: Test1,2,5,4,6,4,5,6 (3 is still missing) This is independent of the "-R" parameter. I could also experience this issue when using one-way sync, however, the first one-way sync is still ok, but then messages start duplicating as for the two-way sync without "-R": $ doveadm -o imapc_user="remote(a)DOMAIN.TLD" -o imapc_password="PW" -o imapc_host="localhost" sync -R -1 -u local(a)DOMAIN.TLD imapc: Hope you can replicate this, too, and finally fix the issue. -- Best regards, Sven Strickroth PGP key id F5A9D4C4 @ any key-server

UID to file?
by Carles Pina i Estany 09 May '19

09 May '19

Hello, In the past I was in a situation that given an email UID I wanted to know which file in the Maildir directory this UID was saved. I did a small parser for $HOME/Maildir/dovecot-uidlist where, if the file had: 1000 W1838 S1796 :1557351041.10447_1.example I would ask for the UID 1000 and would return :1557351041.10447_1.example (and I knew that it was in $HOME/Maildir/new) Is there any other way using dovecot tools to do the same, to avoid parsing an internal dovecot file? Thank you! -- Carles Pina i Estany GPG Key 0x8CD5C157

Push Notification clarification (MessageNew w/o LMTP or LDA)
by Christian Balzer 09 May '19

09 May '19

Hello, Both the examples on the Push Notification wiki page and the XAPS plugin docs seem to suggest or state that LMTP/LDA is required. However IMAP IDLE notifications work without either of these (please no religious discussion of why Dovecot LMTP is the best thing since sliced bread and that everybody should use it). The LUA part of the push notification docs however states that events other than MessageNew are supported. So my question is, when not using LMTP/LDA and a LUA script and of course the correct mail_plugins definition (either global or for IMAP), will a message delivery trigger MessageNew?

I see the Virtual/ prefix available as a noselect folder in the list of unsubscribed folders and if I manual subscribe to it, folder tree display is perfect. So how can i also make auto-subscription to the "Virtual/" prefix noselect folder?

Toward that end, is it possible to “merge” two different mail directories (either maildir or mdbox) via doveadm? “doveadm backup” looks like the closest match, but it doesn’t appear to accept an arbitrary directory as its synchronization source. Thank you! -Felipe Gasper Mississauga, Ontario

Dovecot does not recognize imported messages
by lty 08 May '19

08 May '19

Today I tried to import mail directly on the server's home directory on the server. I copied it directly. I didn't use the imap protocol. Dovcot didn't recognize these emails. I didn't display these imported emails on my page, recalculating disk quotas. It will not increase the used capacity. I try to send an email to this user, dovcot recognizes all the emails, and recalculates the disk cooperation, this time is correct. Why can't I identify the mail I imported? > [root@imap2 ~]# dovecot -n > # 2.2.36 (1f10bfa63): /etc/dovecot/dovecot.conf > # Pigeonhole version 0.4.24 (124e06aa) > # OS: Linux 2.6.32-431.el6.x86_64 x86_64 CentOS release 6.5 (Final) > # Hostname: imap > auth_master_user_separator = * > auth_mechanisms = PLAIN LOGIN > default_internal_user = vmail > default_vsz_limit = 2 G > deliver_log_format = msgid=%m, subject=%s, from=%f, %$ > dict { > acl = mysql:/etc/dovecot/dovecot-share-folder.conf > quotadict = mysql:/etc/dovecot/dovecot-used-quota.conf > } > disable_plaintext_auth = no > first_valid_uid = 2000 > last_valid_uid = 2000 > listen = * > mail_fsync = never > mail_gid = 2000 > mail_location = maildir:/%Lh/Maildir/:INDEX=/%Lh/Maildir/ > mail_plugins = quota lazy_expunge zlib fts fts_solr > mail_uid = 2000 > maildir_stat_dirs = yes > 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 > mmap_disable = yes > namespace { > list = children > location = maildir:/%%Lh/Maildir/:INDEX=/%%Lh/Maildir/Shared/%%u > prefix = Shared/%%u/ > separator = / > subscriptions = yes > type = shared > } > namespace { > hidden = yes > list = no > location = maildir:/var/vmail/backup/expunged/%d/%n > prefix = .DELETED/ > separator = / > } > namespace inbox { > inbox = yes > location = > mailbox Drafts { > auto = subscribe > special_use = Drafts > } > mailbox Junk { > auto = subscribe > special_use = Junk > } > mailbox Sent { > auto = subscribe > special_use = Sent > } > mailbox Trash { > auto = subscribe > special_use = Trash > } > prefix = > separator = / > } > passdb { > args = /etc/dovecot/dovecot-mysql.conf > driver = sql > } > passdb { > args = /etc/dovecot/dovecot-fallback-password-mysql.conf > driver = sql > } > passdb { > args = /etc/dovecot/dovecot-fallback-mysql.conf > driver = sql > } > passdb { > args = /etc/dovecot/dovecot-master-users-password > driver = passwd-file > master = yes > } > plugin { > acl = vfile:/etc/dovecot/dovecot-acl > acl_globals_only = yes > auth_socket_path = /var/run/dovecot/auth-master > fts_autoindex_exclude = Junk > fts_autoindex_exclude2 = Trash > fts_autoindex_exclude3 = Sent > fts_autoindex_exclude4 = Drafts > fts_autoindex_max_recent_msgs = 20 > lazy_expunge = .DELETED/ > mail_replica = tcp:10.0.11.152:1111 > quota = dict:user::proxy::quotadict > quota_grace = 0%% > quota_max_mail_size = 70M > quota_rule = *:storage=1G > quota_rule2 = *:messages=0 > quota_warning = storage=85%% quota-warning 85 %u > quota_warning2 = storage=90%% quota-warning 90 %u > quota_warning3 = storage=95%% quota-warning 95 %u > sieve = /%Lh/sieve/dovecot.sieve > sieve_default = /var/vmail/sieve/dovecot.sieve > sieve_default_name = managesieve > sieve_dir = /%Lh/sieve > } > protocols = pop3 imap sieve > service anvil { > client_limit = 20500 > } > service auth { > client_limit = 20500 > unix_listener /var/spool/postfix/private/auth { > group = postfix > mode = 0666 > user = postfix > } > unix_listener auth-master { > group = vmail > mode = 0666 > user = vmail > } > unix_listener auth-userdb { > group = vmail > mode = 0660 > user = vmail > } > } > service dict { > unix_listener dict { > group = vmail > mode = 0660 > user = vmail > } > } > service imap-login { > process_min_avail = 24 > service_count = 0 > vsz_limit = 2 G > } > service imap { > process_limit = 1024000 > process_min_avail = 24 > vsz_limit = 2 G > } > service pop3-login { > service_count = 0 > } > service quota-warning { > executable = script /usr/local/bin/dovecot-quota-warning.sh > unix_listener quota-warning { > group = vmail > mode = 0660 > user = vmail > } > } > ssl_ca = </etc/pki/tls/certs/c.cn.ca-bundle > ssl_cert = </etc/pki/tls/certs/c.cn.crt > ssl_key = # hidden, use -P to show it > syslog_facility = local6 > userdb { > args = /etc/dovecot/dovecot-mysql.conf > driver = sql > } > userdb { > args = /etc/dovecot/dovecot-fallback-user-mysql.conf > driver = sql > } > protocol lda { > auth_socket_path = /var/run/dovecot/auth-master > lda_mailbox_autocreate = yes > mail_fsync = optimized > mail_plugins = quota lazy_expunge zlib fts fts_solr sieve > syslog_facility = local6 > } > protocol imap { > imap_client_workarounds = tb-extra-mailbox-sep > imap_id_send = NAME dovecot VERSION 2.1.17 > mail_max_userip_connections = 20 > mail_plugins = quota lazy_expunge zlib fts fts_solr imap_quota mail_log imap_zlib notify > } > protocol pop3 { > mail_max_userip_connections = 20 > mail_plugins = quota lazy_expunge zlib fts fts_solr mail_log notify > pop3_client_workarounds = outlook-no-nuls oe-ns-eoh > pop3_uidl_format = %08Xu%08Xv > }

Hello, just a question, I can't see a core "release-2.3.6" branch, nor a pigeonhole "release-0.5.6" branch on the GIT repository, it is outdated? or do you have changed your policy to create a new branch for each new release of dovecot and pigeonhole?

Symlinked mailboxes and dovecot-uidlist.lock
by Dave 07 May '19

07 May '19

I have a scenario where I have two users, one account (user1) with it's own Maildir account, and another account (user2) (which I wish to see the same messages) with a symlinked Maildir to user1's Maildir. I.E.: /home/user1/Maildir /home/user2/Maildir (where this Maildir is symlinked to /home/user1/Maildir) Both users are in a group together (usergroup), and so all of the permissions on the Maildir, new, cur, etc folders are rwxrwx--- or rw-rw----. All mail gets created and delivered correctly, both users can move and create files, and everything generally seems to be working fine. However, I did notice one error showing up in the system logs: May 2 11:35:13 userserver dovecot: imap(user1): Error: inotify_add_watch(/home/user1/Maildir/dovecot-uidlist.lock) failed: Permission denied May 2 11:36:27 userserver dovecot: imap(user2): Error: inotify_add_watch(/home/user2/Maildir/dovecot-uidlist.lock) failed: Permission denied May 3 10:10:11 userserver dovecot: imap(user2): Error: inotify_add_watch(/home/user2/Maildir/.Folder1/dovecot-uidlist.lock) failed: Permission denied I've managed to catch a glimpse of a lock file, as it comes and goes very quickly, and it is permissioned as so: -rw-rw---- 1 user1 usergroup 10 May 5 11:39 dovecot-uidlist.lock So I'm not sure what exactly the permissions issue is then? The file seems to have the appropriate group permissions for each user to read from and write to it. Again, this is the only error I'm getting, and everything has been working fine. I did read the Dovecot wiki talking about symlinking mailboxes, and it refers to symlinking each box/folder individually and not the entire Maildir folder as I've done, but since each individual box/folder has its own dovecot-uidlist I imagine I might run into this same issue anyway? Anyway, I'd like to squelch the error if I can, so are there any thoughts as to why the lock files are having trouble with inotify_add_watch? -Dave

doveadm - mailbox to filesystem directory?
by Joaquin F 07 May '19

07 May '19

Is it possible to get the filesystem location (directory name) for a given mailbox? The closest I found was parsing the output of "doveadm -D mailbox create", but this only works if the mailbox doesn't exist yet and prone to failure if the debug output changes in future versions. Using "doveadm mailbox mutf7" helps, but there's some ASCII characters which are encoded. So far I've found "\" turns in to "\5c", "." into "\2e" and "/" to "\2f" and the separator to ".". But maybe there are others. Thanks in advance. Version: dovecot 2.2.36 (1f10bfa63) Relevant config: mail_location = maildir:~/Maildir protocols = imap namespace inbox { separator = "$" }

regression with lmtp_hdr_delivery_address in 2.3
by dovecot-ffe7＠ryanc.org 07 May '19

07 May '19

Hi, In my LMTP config, I have lmtp_hdr_delivery_address = none. Under 2.2, Received headers looked like this: Received: from smtp.example.com by lmtp.example.com with LMTP id +IVdKS81cFwWagAAGhmRSA ; Fri, 22 Feb 2019 17:45:19 +0000 After the update to 2.3, they look like this: Received: from smtp.example.com by lmtp.example.com with LMTP id MJbKAMFEclyKCQAAGhmRSA (envelope-from <yyy(a)example.net>) for <xxx(a)example.com>; Sun, 24 Feb 2019 07:16:17 +0000 In both cases I *do not* have a "Delivered-To" header I do see a check for rcpt_to == NULL in the smtp_server_transaction_write_trace_record function, but it looks like the lmtp_local_add_headers function does not update the transaction, so it doesn't get pulled in. Also, the LMTP settings struct isn't exposed in that function currently, and I'm not sure how to add it. In 2.2, both the "Delivered-To" and "Received" headers were handled by client_get_added_headers. Please CC me in replies, as I am not subscribed to the list. Thanks, Ryan

http-lib test failures when building dovecot-2.3.5 and later in mock builder
by Tuomo Soini 07 May '19

There is random failure in test-http-payload when building rpm package from 2.3.6. I couldn't reproduce that in normal system but that happens something like every second try in mock chroot build envirnoment. Other tests don't have issues so it looks like test is not very reliable. Building 2.3.4 didn't yet have this issue. ./test-http-payload -D output attached. -- Tuomo Soini <tis(a)foobar.fi> Foobar Linux services +358 40 5240030 Foobar Oy <https://foobar.fi/>

dynamic virtual mailboxes?
by MRob 06 May '19

hi, I spent time learning about virtual mailboxes. Is there some way to create dynamic virtual mailboxes? I mean, when I look at a mailbox, I want to see only unread messages or flagged messages in that mailbox.

Understanding virtual mailboxes (examples in 15-mailboxes.conf)
by MRob 05 May '19

05 May '19

The examples in 15-mailboxes.conf # If you have a virtual "All messages" mailbox: #mailbox virtual/All { # special_use = \All # comment = All my messages #} # If you have a virtual "Flagged" mailbox: #mailbox virtual/Flagged { # special_use = \Flagged # comment = All my flagged messages #} They seem to reference some kind of virtual mailbox setup that doesn't compare to the docs for the "virtual" plugin. That plugin says we should create a separate namespace instead, like "namespace virtual" and put files representing the virtual folders into user maildirs. What if we use mdbox? add the files to user/mailboxes director I will guess. Is there a way to use the mailbox examples in the inbox namespace in the default config? Does it use some other method different from the virtual plugin? maybe more config hints for those examples would be helpful. Thank you.

Feature request: exclude IP/network in allow_nets extra field
by Zhang Huangbin 01 May '19

01 May '19

Dear all, We use `allow_nets`[1] to restrict login clients, it works fine. Recently we need to allow some users to login from everywhere except some IP/networks, how can we accomplish this with "allow_nets"? Tried allow_nets="!a.b.c.d", but Dovecot reports error "allow_nets: Invalid network '!a.b.c.d'". Can we have this feature? i guess it should be done in function "auth_request_validate_networks"[2] in file src/auth/auth-request.c. [1] allow_nets: https://wiki.dovecot.org/PasswordDatabase/ExtraFields/AllowNets [2] https://github.com/dovecot/core/blob/fbc3ccc4a9a02b82073585a33254eacedc6a99…
