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? Cheers tobi

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. HOSTNAMEOLD HOSTNAMENEW +--------------+ +--------------+ | SENDMAIL | | SENDMAIL | | | | | | | | | | | V | | V | |--------------| |--------------| | lmtp | | NS /INBOX | | | | | mbox on | | V | | block device | |--------------| | | | NS /INBOX | |--------------| | mdbox on | | NS /ARCHIVE | | block device | | mdbox on | | | | clustered fs | |--------------| | | | NS /ARCHIVE | +--------------+ | mdbox on | | clustered fs | | | +--------------+

email notification regression between 2.2 and 2.3
by Thomas Capricelli 14 May '19

14 May '19

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

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

One more obvious line from the log: dovecot[26621]: auth: Error: LDAP: Connection lost to LDAP server, reconnecting Where it claims to reconnect, but after that there is no LDAP authentication. And the same configuration has worked fine since at least 10 years ago up to some recent update of dovecot or openldap. Best Dag

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

Re: Dovecot does not recognize imported messages

I changed the user permissions, this is a must.

Dovecot not surviving OpenLDAP restart
by Dag Nygren 09 May '19

09 May '19

Hi! Running Dovecot 2.2.36 and authenticating against an OpenLDAP 2.4.45 server. Now since some update of dovecot it will not be able to authenticate your logins after a restart of the LDAP service is restarted without a reboot of the dovecot server. Anything new here that I should be aware of? Best Regards Dag

dovecot dict protocol
by Peter Hudec 09 May '19

Hi there is there any written specification for dovecot dict protocol instead of the code? Small example is in docs on https://wiki.dovecot.org/AuthDatabase/Dict and theere is link for all commands/reply in the code https://wiki.dovecot.org/AuthDatabase/Dict I’m writing small dict server and need some explanation for CMD: I, what does the flags means and how should the result looks like CMD: D, I thing this is the same as C, but coud be done later /async/ The reply codes are not very clear. I understand O, N, F. The rest is strange to me. Maybe this is good question do devel mailing list. regards Peter

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?

How to auto-subscribe to virtual namespace/prefix?
by MRob 09 May '19

09 May '19

In virtual namespace I can have: namespace myvirt { location = blah prefix=Virtual/ separator=/ mailbox "My folder" { auto = subscribe } } And i see email clients successful display subscribed "My folder" but the top-level prefix "Virtual/" is not subscribed. 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?

dsync to backup to directory?
by Felipe Gasper 08 May '19

08 May '19

Hello, We have a hosting operation and are interested in offloading mail for some of our machines to a separate machine. We want the ability, though, to migrate accounts between the “offloaded” and “unified” configurations. 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
