Re: Gnu sieve vs Dovecot sieve-filter - sieve-filter extremely slow at lda (writing emails to local mbox files)
by Zenaan Harkness 12 Sep '19

12 Sep '19

(I did subscribe to this mailing list, albeit with zen at freedbms.net, so either way I'm getting all your emails - thank you -so- much for replying...) MUA is mutt, reading email in a terminal (sorry, forgot to mention this before). For many years now my email folder (mbox files) collection has grown to many GiB, mostly mailing lists. If I am to change email storage format, it should be mutt compatible; looking at https://wiki2.dovecot.org/MailboxFormat I see that only DJB's Maildir is … [View More]compatible with both Dovecot ("a reliable choice" says the wiki), and mutt. I can imagine that sdbox or mdbox could be made "mutt compatible" so to speak, by running some sort of local IMAP server, and accessing my email from mutt that way; this is undesirable to my mind because this would require: 1) a new learning curve wrt mutt and reading email on IMAP servers 2) a new learning curve to set up a local IMAP server (securely) 3) the inability to use mutt without a local IMAP server to read my local email but such a setup would also have some quite desirable benefits: 1) once set up, multiple MUAs could be used, and I'd have a beginning grasp on setting up an IMAP server and front ends (this is something on my bucket list, to assist my local church with) 2) simpler remote "online" access to my local "offline" email store (e.g. using my mobile phone when on the road) by setting up a webmail server (much simpler (read "possible" to use on a mobile phone) than using a vpn and mutt...), thus freeing me up from the behemoth web email providers... Next, I do not know how to "pipe the messages to the dovecot lda". After downloading from my POP3 provider into a local mbox file (this is my step 1), then I sort the emails (this is my step 2): the following should be on a single line: /usr/bin/sieve-filter -veW -c $HOME/etc/email/sieve-dovecot-config.conf -o mail_location=mbox:~/mail:INBOX=~/mail/Inbox:INDEX=:UTF-8:VOLATILEDIR=/tmp/dovecot-volatile/%2.256Nu/%u:SUBSCRIPTIONS=dovecot_subscriptions ~/etc/email/sieve.rc email-incoming-unsorted As you can see from the above command, sieve-filter is given the name of the mbox ("mail folder") to sort, as its very last argument on the command line - so in this instance, sieve-filter really has no excuse, and should be not be re-reading the sieve rules script for each email - now perhaps that's not happening, I only made an assumption because of a CPU hitting 100% for a minute or two just to process a few 100 emails... What could also be happening (again, an assumption), is that sieve-filter is written to assume dovecot index files to be in existence. I disabled those with the "INDEX=" clause you see in the command above, which obviously has been given no value. The reason I figured out how to disable the creation of the indexes in the .imap directories, is that for my setup, Gnu sieve has proven that I should not need such indexes - with mbox files, just append each email to the end of the target "mailbox folder" mbox file, and we're done! This literally should not cost 100% CPU, even for one millisecond! But more importantly, because my working email folder is ~30GiB, without disabling this index creation step, sieve-filter forced the creation of indexes, which "took so long I gave up and hit CTRL-C, which did not work, so I kill -9'ed the sieve-filter and whatever other process was not stopping". Last year someone on debian-user recommended I upgrade to using Dovecot/Pigeonhole's sieve-filter (rather than Gnu sieve) due to the issues with Gnu sieve. I am starting to think that I should perhaps try to figure out if it's possible to (re)process the emails Gnu sieve has a problem with, to massage them into a shape that Gnu sieve accepts - then my immediate problem would certainly be solved... Thank you all again.. Zenaan [View Less]

Case sensitive problem for vacation with dovecot lmtp pigeonhole
by kadafax＠gmail.com 11 Sep '19

11 Sep '19

Hi list, This issue was raised here by John Fawcett on 12/02/19 but got no response. So, as I'm facing the same issue, I would like to try again: When using the vacation sieve extension, if I send an email to user.name(a)mydomain.com it will work, but not to User.Name(a)mydomain.com. Is there a way to make the user part case insensitive so that the vacation auto-reply is fired whatever the way user part is written ? doveconf -n output: # 2.3.5.1 (7ec6d0ade): /usr/local/etc/dovecot/… [View More]dovecot.conf # Pigeonhole version 0.5.5 (2483b085) # OS: Linux 3.10.0-957.5.1.el7.x86_64 x86_64 CentOS Linux release 7.6.1810 (Core) ext4 # Hostname: myserver.mydomain.com auth_master_user_separator = * auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@* auth_verbose = yes debug_log_path = /var/log/dovecot-debug.log default_client_limit = 10640 default_process_limit = 2128 default_vsz_limit = 0 hostname = mydomain.com info_log_path = /var/log/dovecot.log lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes listen = * log_path = /var/log/dovecot-error.log login_greeting = Welcome mail_gid = vmail mail_location = maildir:/var/vmail/%Ln mail_plugins = quota fts fts_lucene mail_uid = vmail 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 { inbox = yes location = maildir:/var/vmail/%Ln mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Sent { auto = subscribe special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = type = private } passdb { args = /usr/local/etc/dovecot/deny-users deny = yes driver = passwd-file } passdb { args = /usr/local/etc/dovecot/master-users driver = passwd-file master = yes pass = yes } passdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { fts = lucene fts_autoindex = yes fts_lucene = whitespace_chars=@. quota = maildir:User quota quota_rule = *:storage=30GB quota_rule2 = Trash:storage=+200M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u sieve = /var/sieve-scripts/%Ln.sieve sieve_dir = /var/vmail/%Ln/home/sieve } postmaster_address = postmaster(a)mydomain.com protocols = imap pop3 lmtp sieve sieve quota_full_tempfail = yes service auth-worker { user = $default_internal_user } service auth { unix_listener /var/spool/postfix/private/auth { mode = 0777 user = vmail } } service imap-login { inet_listener imaps { port = 993 ssl = yes } process_min_avail = 10 } service imap { process_limit = 2128 } service lmtp { executable = lmtp -L process_min_avail = 15 unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service managesieve-login { inet_listener sieve { port = 4190 } } service pop3-login { inet_listener pop3s { port = 995 ssl = yes } } service quota-warning { executable = script /usr/local/bin/quota-warning.sh user = nobody } ssl_cert = </etc/letsencrypt/live/myserver.mydomain.com/fullchain.pem ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { args = /usr/local/etc/dovecot/dovecot-ldap-userdb.conf.ext driver = ldap override_fields = uid=vmail gid=vmail home=/var/vmail/%Ln/home } protocol imap { mail_max_userip_connections = 30 mail_plugins = quota fts fts_lucene imap_quota } protocol lmtp { info_log_path = /var/log/dovecot-lmtp.log log_path = /var/log/dovecot-lmtp-errors.log mail_plugins = quota fts fts_lucene sieve } protocol sieve { mail_max_userip_connections = 20 } [View Less]

Quota and maildir does not work with subfolders of INBOX
by Niels Kobschätzki 11 Sep '19

11 Sep '19

Hi, we just upgraded on FreeBSD (11.2-p14) from Dovecot 2.2 to Dovecot 2.3.7.2 and now we have kind of a big problem: the quota-plugin does not work correctly anymore. If a user has a subfolder of the INBOX (like .INBOX.foobar) the quota-calculation does not work anymore. It seems to be arbitrary but users get counted like double and more than they actually have in mails (the number of mails is correct, but the size gets calculated wrongly). The moment I remove those folders, the size gets … [View More]

I’d like to synchronise our mail store to an Amazon S3 bucket or similar, for protection from ransomware. Server is running on macOS with maildir. Should I use a Dovecot process, rsync, a Mac app like Arq or Jungle Disk, or something else? Anyone have experience or opinions on this? Thanks, James.

Random duplicated emails
by Francis 11 Sep '19

11 Sep '19

Hello, I migrated our mail infrastructure to Dovecot on Ubuntu 18.04 some months ago. It works fine, but recently some users told me that they sometime receive duplicated emails. Same email content, same headers including message-id. I'm using two dovecot servers on two sites. Both server are in cluster. We don't use shared folders. All users that reported this issue so far are using the same server instance. The problematic emails are coming from local users on that instance too. The … [View More]examples they given to me was emails with many recipients (To/CC). A specific message can be received twice (or more) by recipient A but only once by recipient B. I didn't see anything in the logs about sieve rules that redirect emails to others recipients. Where should I look to diagnostic this issue? Thanks.

Hi, I have a setup with 3 Dovecot Director v2.2.36 and director_consistent_hashing = yes ;-) Now I would like to upgrade to 2.3.7, first only Director and after also Backend. Can works fine a ring of director with mixed 2.2 and 2.3 version? Mi idea is to setup a new Director server with 2.3, stop one server with 2.2 and insert the new 2.3 in the current ring to check if works fine. If all works fine I will replace all Director 2.2 with 2.3 version. Thanks -- Alessio Cecchi Postmaster … [View More]

New to dovecot admin, question about testing a dovecot configuration

I am new to dovecot administration, not new to postfix administration. When setting up a new postfix/dovecot combo from scratch, can I start with dovecot alone and still be able to test it? E.g. can I address the local delivery agent with some sort of test email? If so, how? I haven’t been able to find it in the wiki.

Force dovecot-uidlist reset
by Tom Sommer 09 Sep '19

Is there a way to force Dovecot to rebuild dovecot-uidlist from zero? It seems deleting all indexes and dovecot-* files followed by "doveadm force-resync" is not enough? It just gets the same UIDs? Perhaps from Maildir filenames? But I would like to reset the uid of all mails. Thanks -- Tom

It's quite likely I'm doing it wrong, but... Given a valid mailbox... doveadm mailbox list -u <username> realmb returns "realmb" doveadm mailbox list -u <username> real* returns "realmb" Seems reasonable. Now, with a non-existent mailbox... doveadm mailbox list -u <username> bogus returns "bogus" doveadm mailbox list -u <username> bogus* returns "" Is this a bug or correct behavior? -- Daniel

login failure after upgrade to dovecot 2.3.7.2
by MK 05 Sep '19

Hi List, after upgrading dovecot from version 2.2.33.2 to 2.3.7.2 I got a lot of error messages like the following if the process count of imap processes reaches nearly 1000 (~950 (there are a few pop-connections)). Sep 5 11:27:32 mailbox1 dovecot: imap-login: Internal login failure (pid=27728 id=116): user=<xxxx(a)xxxx.xx>, method=PLAIN, rip=x.x.x.x, lip=x.x.x.x, session=<qETa7cqRzpZV3IEw> Sep 5 11:27:33 mailbox1 dovecot: imap-login: Error: master(imap): net_connect_unix(imap) … [View More]failed: Resource temporarily unavailable - http://wiki2.dovecot.org/SocketUnavailable (client-pid=27704, client-id=79, rip=x.x.x.x, created 511 msecs ago, received 0/4 bytes) Our setup consists of some servers with dovecot as proxy/redirector as frontend servers, redirecting the logged in users to the backend servers storing the mailboxes. OS is CentOS 6 on both server types. The backend server in question has usually ~ 2500 simultaneous imap connections. Before the update there where no problems. During the update I merged the old 2.2 config into the new 2.3 from the fresh installed binary (Repo from dovecot.org) As I found the failure above in the logfile I testet a lot, to figure out how to fix this, because for me it seemed to be some limit around 1000 connections/processes anywhere in the config. In the end I changed the default value of "default_client_limit" from ist default 1000 to 8192 and the problem was fixed for the moment. Now I'm trying to understand why this fixes the problem and what the difference is between 2.2 and 2.3. For me it seems like something changed in the architecture during the release change, but I didn't find anything. I looked into the release notes and also checked the differences beween the 2.2 and 2.3 default config values (using doveconf -d). Can anyone help?

dsync and altpath on shared storage.
by Peter Mogensen 05 Sep '19

Hi, I was wondering... If one had mdbox ALT path set to a shared storage mount (say, on NFS) and one wanted to move a mailbox to a different host... I guess it in principle wouldn't be necessary to copy all the ALT storage through dsync, when the volume could just be mounted on the new host. Is there anyway for dsync to avoid moving Gigabytes of data for could just be "moved" by moving the mount? /Peter

Dovecot and Apple's Mail.app not playing nicely?

Hi all, Is there anything cute one has to take into account when using Dovecot with users of Apple’s Mail.app? Behavior I’m seeing is that if I delete or move messages via Webmail (Roundcube, Horde, or even ActiveSync via Mail.app on my phone), they do get moved or deleted. However, if I take the same actions in the desktop mail client, when logging in to the Webmail (or phone) app, I see the messages still seeming to be in the Inbox. Is this known behavior?

Re: Re: Quota count and clone questions
by Bratislav ILIC 03 Sep '19

03 Sep '19

Hi, I presume you figured this out after all this time, but in any case. Since quota_clone is not cumulative, it always inserts new record with actual quota, to be able to get correct results in postfixadmin one must: DROP TRIGGER mergequota2 ON quota2; And to prevent ERROR: duplicate key value violates unique constraint "quota2_pkey": CREATE FUNCTION public.clone_quota2() RETURNS trigger LANGUAGE plpgsql AS $$ BEGIN UPDATE quota2 SET bytes = NEW.bytes, … [View More] messages = NEW.messages WHERE username = NEW.username; IF found THEN RETURN NULL; ELSE RETURN NEW; END IF; END; $$; And then: CREATE TRIGGER clonequota2 BEFORE INSERT ON quota2 FOR EACH ROW EXECUTE PROCEDURE public.clone_quota2() ; And finally just put: quota_clone_dict = proxy::sqlquota Hope this helps somebody trying to figure out this too. > I figured out that I can't just drop maintaining quota2 if I want > postfixadmin to report the quota status. > > I also figured out a way to run a test on my config guesses.

LMTP Post login script for acl_groups
by lists＠mlserv.org 03 Sep '19

03 Sep '19

Hi, I use a post login script for imap, to fetch acl groups from LDAP. Because Dovecot can only deal with a single value, which must be a comma seperated list of groups, I decided to use a post login script do deal with multi values in LDAP: This looks like this in LDAP: rnsMSACLGroup: admin rnsMSACLGroup: automx rnsMSACLGroup: amavis rnsMSACLGroup: postfix rnsMSACLGroup: dovecot rnsMSACLGroup: rspamd rnsMSACLGroup: powerdns rnsMSACLGroup: sogo rnsMSACLGroup: zabbix rnsMSACLGroup: dane-users … [View More]rnsMSACLGroup: gentoo rnsMSACLGroup: openbsd My post login script looks like this: --------------------------------------------------------- #!/bin/sh BINDDN='cn=dovecot-postlogin,ou=people,ou=it,dc=roessner-net,dc=de' BINDPWFILE='/etc/dovecot/ldap-postlogin.secret' BASE='ou=people,ou=it,dc=roessner-net,dc=de' LDAPSEARCH="/usr/bin/ldapsearch" AWK="/usr/bin/awk" test -x ${LDAPSEARCH} || exec "$@" test -x ${AWK} || exec "$@" ACL_GROUPS=$( ${LDAPSEARCH} -LLL -ZZ -y ${BINDPWFILE} -xD ${BINDDN} -b ${BASE} "(rnsMSDovecotUser=${USER})" rnsMSACLGroup | \ grep rnsMSACLGroup | \ ${AWK} -vORS=, '{ print $2 }' | \ sed 's/,$/\n/' ) export ACL_GROUPS export USERDB_KEYS="${USERDB_KEYS} acl_groups" exec "$@" --------------------------------------------------------- This script is included in imap-postlogin executables and works for logged in users. But it does not work for LMTP. LMTP itself seems not to have any permissions to access the folders associated with these groups. I thought, I simply could add the imap-postlogin block to lmtp-postlogin and that would work, but it doesn't. So here is the question: What am I missing in Dovecot that LMTP can also have ACL_GROUPS like the imap service? Here is my config (non-defaults): --------------------------------------------------------- doveconf -n # 2.3.7.1 (0152c8b10): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.7.1 (db5c74be) # OS:

Hi, >From the v2.2.36.4 announcement message: "Binary packages are available at https://repo.dovecot.org/" My question is, where exactly? There's an instruction at repo.dovecot.org that tells you to replace 'ce-latest-2.3' with 'ce-<version>' but the given url doesn't even contain 'ce-latest-2.3' and http://repo.dovecot.org/ce-2.2.36 returns a 404. Thanks in advance! bvr.

flags not synced correctly with dovecot sync (dsync)
by Dan Christensen 31 Aug '19

31 Aug '19

I'm running dovecot 2.3.4.1 from https://repo.dovecot.org/ on Ubuntu 18.04 on three machines that I'll call server, laptop1 and laptop2. Both laptop1 and laptop2 run dovecot sync against server to keep local copies of my imap folders. Even when I initially had only two machines, laptop1 and server, I occasionally noticed that flags were lost, usually custom flags used by Gnus, but I couldn't reliably reproduce the problem. Now that I have two laptops syncing against the server, the problem … [View More]has gotten worse and I figured out a way to reproduce it: - on server: create new IMAP folder test, and put two read messages in it - on laptop1: doveadm sync -u user -l 10 -m test -f user@server - on laptop2: doveadm sync -u user -l 10 -m test -f user@server At this point, all three machines show the two messages M1 and M2 as being read. - on laptop1: mark message M1 unread - on laptop2: mark message M2 unread - on laptop1: doveadm sync -u user -l 10 -m test -f user@server Both laptop1 and server have M1 unread, M2 read, as expected. - on laptop2: doveadm sync -u user -l 10 -m test -f user@server Now laptop2 and server have M1 *read*, M2 unread. - on laptop1: doveadm sync -u user -l 10 -m test -f user@server Now laptop1 and the server have both M1 and M2 *read*. - on laptop2: doveadm sync -u user -l 10 -m test -f user@server Now laptop2 has both read as well. The two lines that say "*read*" are wrong in my opinion. dsync propagated a read mark to an unread message, even though that message was marked unread more recently than it was marked read. I usually use stateful sync, and get many related problems. I just did a test in which M1 and M2 started out read, and I started with empty files named dstate.test on laptop1 and laptop2. Then I did the above procedure, using the command doveadm sync -u user -l 10 -m test -s "`cat dstate.test`" user@server > dstate.test At the end, laptop2 and server had both messages unread (which is good), but laptop1 had only M1 unread, and repeated runs of the sync command did not correct this. So the stateful sync failed to detect a change. Are these bugs in dovecot? Is there more information that I can provide? The output of doveconf -n on one machine is below, and the others are almost identical. Thanks for any help!

doveadm backup mdbox - initial copy slow
by Gerald Galster 30 Aug '19

30 Aug '19

Hello, when calling doveadm backup like in the following example, it seems to flush every email to disk maxing out harddrives (iops) and resulting in very poor performance: Calling doveadm -o plugin/quota= backup -u "statusmails(a)domain.com" "mdbox:/backup/vmail/domain.com/statusmails" finished in 212 secs [changes:1800 copy:1800 delete:0 expunge:0] The source mdbox holds 1800 small emails and uses about 20 MB disk space only. I've tried -f (full sync) and -l 30 (locking the mailbox) which … [View More]

Hi all, Is there any reason Dovecot shows the 'user' variable (ie: user(a)domain.tld) being obtained in the password query and not the (more logical) user query? Thanks, Michael

Feature wishlist: Allow to hide client IP/host in submission service

In Postfix that's possible (https://serverfault.com/q/413533/86332) but not very nice to configure especially if you only want want to strip the Received header for port 587 submissions, but not on port 25. As far as I can see this configuration is not possible at all in the Dovecot submission server because the … [View More]
