What causes folders to be reported as noselect?
by Daniel Miller 27 Sep '18

27 Sep '18

As the subject says. This may be a bit open-ended - but it would really help troubleshooting some obscure folder issues. In my case, I happen to have both some "real" folders and also some "virtual" folders that respond to IMAP LIST commands with the "\NoSelect" flag - and I don't know why. Via telnet, I can manually issue SELECT, SEARCH, and FETCH for such folders without errors. -- Daniel

Possible bug - otherwise a public admission of oops
by Daniel Miller 27 Sep '18

27 Sep '18

While trying to identify possible causes of wrong mail folder creation I did something...bad. Normally, I would recognize that deleting a mail folder would naturally delete all the contained mails. However...somehow my imaginative self decided that deleting a virtual folder via IMAP would only delete the virtual folder...and not proceed to delete every referenced email via the virtual mapping. So note to self, and possible reminder to others, deleting a virtual folder via a filesystem command is just tiny bit different than via IMAP... Fortunately I keep my feathers numbered for just such an emergency... -- Daniel

dovecot/FreeBSD and Android IMAP clients
by Victor Sudakov 25 Sep '18

25 Sep '18

Dear Colleagues, I have a fairly vanilla setup of dovecot on FreeBSD, serving IMAP and POP3. Thunderbird/IMAP works fine, and so does mutt/IMAP. However, Android clients (Gmail/IMAP and K-9 Mail) have problems accessing folders other than the INBOX. They either show them empty with no mails (K-9) or just wait forever to view the contents (Gmail app). Do I need to set up some workarounds or hacks in dovecot for Android IMAP clients to work correctly? Any advice is appreciated. My config is below: # 2.3.2.1 (0719df592): /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 11.2-RELEASE-p3 amd64 # Hostname: admin.sibptus.ru mail_location = mbox:~/Mail:INBOX=/var/mail/%u mail_privileged_group = mail 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 { driver = pam } protocols = imap pop3 ssl_cert = </usr/local/etc/exim/mail.pem ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { driver = passwd } -- Victor Sudakov, VAS4-RIPE, VAS47-RIPN 2:5005/49@fidonet http://vas.tomsk.ru/

Nightly builds of Debian packages
by Christoph Pleger 24 Sep '18

24 Sep '18

Hello, how is the future of the automatically built nightly debian packages of dovecot? Has that project been ceased? The current auto-built version is still 2.2.28 from April 28, though 2.2.29 (with a security patch) of dovecot is out now for a while. Regards Christoph

Last_login plugin and mysql
by Thomas Hooge 24 Sep '18

24 Sep '18

Hello, i have problems configuring the last_login plugin with mysql. I have extended the postfixadmin database with a new field, configured the plugin as described in the wiki. Finally i got errors: table is not writable, INSERT failed. Why is the insert required? The plugin should only UPDATE the column for existing rows. Or am i missing some configuration options? Here is my dictionary config: map { pattern = shared/last-login/$user table = mailbox value_field = x_last_login value_type = uint fields { username = $user } } Dovecot: 2.2.27 (c0f36b0) Kind regards, Thomas

Error using dsync to convert really old mboxes to Maildir and workaround
by faginbagin 24 Sep '18

24 Sep '18

I ran across what I think may be a bug in dsync when trying to convert from mbox to Maildir format. My first attempt failed with a runaway dsync process spewing out thousands of identical lines of the form: dsync(buus): Error: Duplicate mailbox GUID 00fe691ff60da85b090d0000c8119523 for mailboxes Archive/Personal and Work/VendorInfo - giving a new GUID 00fe691ff60da85b090d0000c8119523 to Archive/Personal These two mail folders happen to be among a number of folders I've had for many years, but also haven't looked at in many years. I used to use UW-IMAP, but switched to dovecot about two years ago, and I'm sure I've never used dovecot to look at those folders. So I suspect the root cause of the above error message was that dovecot had never generated GUIDs for these and some other really old folders. After killing dsync with SIGKILL, which couldn't be killed with SIGTERM, I restored my mbox format Mail folder from backup, restored the mail_location and then coerced dovecot to generate unique GUIDs for all my mail folders with this command: doveadm mailbox status guid `doveadm mailbox list` After the above command, I was able to convert my mail from mbox to Maildir format. Maybe this will help someone else somewhere down the road.

Released Pigeonhole v0.5.3.rc1 for Dovecot v2.3.3.rc1.
by Stephan Bosch 23 Sep '18

23 Sep '18

Hello Dovecot users, Here is the Pigeonhole release candidate that goes with the Dovecot v2.3.3 release candidate. It consists only of bugfixes. Changelog v0.5.3: - Fix assertion panic occurring when managesieve service fails to open INBOX while saving a Sieve script. This was caused by a lack of cleanup after failure. - Fix specific messages causing an assert panic with actions that compose a reply (e.g. vacation). With some rather weird input from the original message, the header folding algorithm (as used for composing the References header for the reply) got confused, causing the panic. - IMAP FILTER=SIEVE capability: Fix FILTER SIEVE SCRIPT command parsing. After finishing reading the Sieve script, the command parsing sometimes didn't continue with the search arguments. This is a time- critical bug that likely only occurs when the Sieve script is sent in the next TCP frame. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.3/rc/dovecot-2.3-pigeonhole-0.5.3.… http://pigeonhole.dovecot.org/releases/2.3/rc/dovecot-2.3-pigeonhole-0.5.3.… Refer to http://pigeonhole.dovecot.org and the Dovecot wiki for more information. Have fun testing this release candidate and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

Global sieve doesn't run and I don't know why
by Ranbir 21 Sep '18

21 Sep '18

Hi Everyone, I have dovecot, postfix, roundcube and piegeonhole managesieve all working nicely together. Personal scripts defined in roundcube run without issue. I have configured the global sieve dir defined in 90-sieve.conf: sieve_global_dir = /var/lib/dovecot/sieve/global/ I pre-compiled the script in there: # ls -l /var/lib/dovecot/sieve/global/ total 8 -rw-r--r--. 1 root root 118 Sep 19 16:52 global.sieve -rw-r--r--. 1 root root 197 Sep 19 16:56 global.svbin But, in the logs for dovecot, I never see the script being run: https://www.pastiebin.com/5ba3faa8628c2 Users are from freeipa. Their home directories are symlinks to where the mail really lives. For example: lrwxrwxrwx. 1 ranbir virtual 42 May 25 2017 ranbir -> /var/spool/mail/domain.tld/ranbir/ And the contents of that dir: [root@mailhost conf.d]# ls -al /home/DOMAIN/ranbir/ total 64 drwxrwx---. 4 ranbir virtual 4096 Sep 18 17:40 . drwxrwx---+ 13 virtual virtual 4096 Jul 8 12:06 .. -rw-------. 1 ranbir ranbir 17808 Sep 20 01:13 .bash_history -rw-------. 1 ranbir ranbir 18 Dec 14 2015 .bash_logout -rw-------. 1 ranbir ranbir 193 Dec 14 2015 .bash_profile -rw-------. 1 ranbir ranbir 231 Dec 14 2015 .bashrc lrwxrwxrwx. 1 virtual virtual 23 Feb 11 2018 .dovecot.sieve -> sieve/managesieve.sieve lrwxrwxrwx. 1 virtual virtual 23 Sep 18 16:53 .dovecot.sieve.log -> sieve/dovecot.sieve.log -rw-rw----. 1 virtual virtual 322 Sep 18 17:40 .dovecot.svbin -rw-------. 1 ranbir ranbir 59 Jun 7 2016 .lesshst drwx------. 56 virtual virtual 4096 Sep 20 15:02 Maildir drwxrwx---. 3 ranbir virtual 89 Sep 18 17:16 sieve -rw-------. 1 ranbir ranbir 6415 Feb 11 2018 .viminfo Did I miss something in the configuration? Dovecot isn't throwing any errors. I can only conclude I haven't completed the setup for global sieve to work or that I've misunderstood what the "sieve_global_dir" paramater is for. Thanks! -- Ranbir

Re: Duplicate mails on pop3 expunge with dsync replication on 2.2.35 (2.2.33.2 works)
by Gerald Galster 21 Sep '18

21 Sep '18

Hi Tim, > Do you have any new insights on the problem with reappearing mail using dovecot replication + pop3? > > It's driving me mad. I'm running dovecot 2.2.34 (874deae) on OpenBSD and it looks like I have the same problem as you have. unfortunately there has been no response, I'm stuck with 2.2.33.2 for the time being. I can only suspect it has something to do with mailbox locking which was introduced in 2.2.34 (int dsync_mailbox_lock) or maybe with some cached values (drop_older_timestamp) as it just happens when the mail is deleted on the node that it has been synced to but not if it's deleted on the node where it has originally been received.

Sieve and output variable for execute
by Adam Raszkiewicz 20 Sep '18

20 Sep '18

I'm trying to get blow Sieve filter to work require ["fileinto", "imap4flags", "mailbox", "body", "envelope", "vnd.dovecot.pipe", "variables", "vnd.dovecot.execute"]; if envelope :matches "To" "*@*" { set "recipient" "${0}"; set "user" "${1}"; set "recip_domain" "${2}"; } if envelope :matches "From" "*" { set "sender" "${0}"; } #Check if recipient is valid user if execute :output "valid_user" "user-verification" "${recipient}" { if string :matches "${valid_user}" "True" { if body :raw :contains ["message/notification"] { setflag "\\Seen"; fileinto :create "Notifications"; stop; } } } Where user-verification is an extprogram which calls API and verify user based on email address then returns boolean (as an output to the console). Everything works fine when I will remove if string :matches "${valid_user}" "True"statement other way it looks like is not recognizing valid_uservariable. When I pipe valid_user to some script just to capture value for that variable it throws an error: error: specified :args item `True?' is invalid. Why question mark was added to the variable in this case? Thoughts?

dovecot.index.pvt reset
by Chris 20 Sep '18

20 Sep '18

All, maybe that's a similar issue like the one mentioned in [1], nevertheless I started a new thread. Using public folders: location = maildir:/var/vmail/public/:LAYOUT=fs:INDEXPVT=%h/.public-indexes When deleting a public maildir in filesystem (rm -rf ...) and copying back from backup, it's older than the users' dovecot.index.pvt files. (%h is in another directory). Then the following error appears: Sep 19 07:27:00 mail1 dovecot: imap(dr): Error: /var/vmail/users/dr/.public-indexes/folder1/folder2/dovecot.index.pvt reset, view is now inconsistent Sometimes even a panic: Sep 19 07:27:00 mail1 dovecot: imap(dr): Panic: file mail-index-map.c: line 548 (mail_index_map_lookup _seq_range): assertion failed: (first_uid <= last_uid) When deleting such a maildir via IMAP or doveadm, the error isn't appearing. Is there anything else, one has to consider, when restoring public maildirs from rsync backup? TIA! Chris [1] 5e26fce3-5f9f-219e-55fb-48981027dca5(a)shift.agency

Hi, we currently work on a fresh setup coming from 2.2.13 going to 2.3.2.1 (0719df592) (Debian Dovecot Repo). We make heavily use of Public Folder with Per-user \Seen flag and Subscription. namespace { type = public separator = / prefix = Verteiler/ location = maildir:/var/vmail/public/example.com/verteiler:SUBSCRIPTIONS=subscriptions… subscriptions = yes hidden = no list = children } With our current version 2.2.13 this setup works. With version 2.3.2.1 we experience errors in the logfile: Sep 8 23:12:27 mail dovecot: Error: imap(user(a)example.com)<11328><e6jPlGJ1IxBOXnhS>: /var/vmail/mailboxes/example.com/user/public/example.com/verteiler/.info/dovecot.index.pvt view is inconsistent dovecot.index.pvt.log is beeing created. We found some appearance of this issue in forums but without any sufficient solution. Is the information provided in this email enough? What else would be relevant? Thank you! Tobias

blacklistd support for dovecot
by Kurt Lidl 20 Sep '18

20 Sep '18

Greetings all! I ported the NetBSD blacklistd support into FreeBSD a while ago (FreeBSD 11.x timeframe). I also added support to several of the system daemons there, so they could all talk to a centralized daemon (blacklistd). One of the third party apps that I added support to was sendmail - that works pretty well. So I'm now finally turning my attention adding blacklistd support to dovecot (which is the imap daemon that I use). I did an implementation to an earlier version, and that worked OK, at least for non-encrypted access to the imap server. However, the encrypted access (TLS) doesn't work right. To authenticate a network connection, the daemon must pass the fd of the remote connection over a unix domain socket to the actual blacklistd daemon. The blacklistd daemon will then call getpeername() on the connection, so it can determine the remote connection endpoint, rather than just having to believe some made-up set of data that is passed to it from process on the local machine. Christos Zoulas' talk on blacklistd is here: https://www.youtube.com/watch?v=fuuf8G28mjs Anyhow -- the problem I've run into is that there doesn't seem to be any way to get access to the fd of the socket that holds the raw connection to the client when TLS encryption is active. It looks like the only connection I get is to the proxy process. Is there any guidance that someone can give with how to implement this? Thank you. -Kurt

HTTP DoveAdm API - Possible bug?
by Chris Malton 19 Sep '18

19 Sep '18

Hi all, It seems that setting userMask in the doveadm http api's "user" command to anything involving wildcards ?s or *s causes the API to fail. When using the API with a userMask set to the fully qualified email address, I get the expected fields back. From a python shell, with an asterisk causes the following behaviour (note that doveadm is a python module that wrappers the dovecot API into Python's requests module). >>> doveadm.do_query("http://[xxxx:xxxx:xxxx:xxxx::ffff]:24280", "API_KEY_HERE", [ ["user", { "userMask": ["*"] }, "c01"] ]) '[["doveadmResponse",,"c01"]]' If I run the same command with a valid mailbox in the userMask Field, I get the response I expect: >>> doveadm.do_query("http://[[xxxx:xxxx:xxxx:xxxx::ffff]:24280", "API_KEY_HERE", [ ["user", { "userMask": ["test(a)test.mydomain.com"] }, "c01"] ]) '[["doveadmResponse",{"test(a)test.mydomain.com":{"uid":"x","gid":"y","home":"/mail/test.mydomain.com/users/test","mail":"maildir:/mail/test.mydomain.com/users/test/Maildir/:INDEX=/indexes/test.myd…","nice":"10"}},"c01"]]' Chatting with people in #dovecot revealed similar behaviour elsewhere so it doesn't appear to be just me. I've also selectively edited the above to avoid leaking data. We're running on the following # 2.2.34 (874deae): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.22 (22940fb7) # OS: Linux 4.9.0-7-amd64 x86_64 Debian 9.5 ext4 If you need a full copy of the config, please let me know and I'll talk to my client, however, I don't think this is config related. Thanks in advance.

dovecot (2.2.13) panic on imap-login from iphone se
by Andre Hoepner - i.based: Systemhaus GmbH + Co. KG 18 Sep '18

18 Sep '18

Hi to all, we have trouble with one user account, when using imap-login with iphone se. The user can login and use the account from webmail (roundcube) and from thunderbird without any errors and without any restrictions. But if we use the account on an iphone se and try to use imap based emails, there comes the following error (look at the end of the mail). I have no idea, what for an error it is. Same account on an iphone 5 works without any trouble. We have delete the homedir of the user and also recreated the user with new uid and new password. Webmail and thunderbird are fine, but if we use the iphone se we got this error. Are there any known issues with this combination? Thanks for your help. best regardings Andre Hoepner ---8<---- # HOST = hostname of the system; USER = username that gets this error Sep 18 12:46:02 HOST dovecot: imap(USER): Panic: file mailbox-list.c: line 1125 (mailbox_list_try_mkdir_root): assertion failed: (strncmp(root_dir, path, strlen(root_dir)) == 0) Sep 18 12:46:02 HOST dovecot: imap(USER): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0x6552e) [0x7f4333e0452e] -> /usr/lib64/dovecot/libdovecot.so.0(+0x65596) [0x7f4333e04596] -> /usr/lib64/dovecot/libdovecot.so.0(i_fatal+0) [0x7f4333dc423e] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_list_try_mkdir_root+0x469) [0x7f43340d3a5a] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_list_mkdir_root+0x15) [0x7f43340d3ac0] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x570cb) [0x7f43340c40cb] -> /usr/lib64/dovecot/libdovecot-storage.so.0(maildir_set_deleted+0x11a) [0x7f43340c465c] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x563d5) [0x7f43340c33d5] -> /usr/lib64/dovecot/libdovecot-storage.so.0(maildir_uidlist_sync_init+0x33) [0x7f43340c34f7] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x517ac) [0x7f43340be7ac] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x51c59) [0x7f43340bec59] -> /usr/lib64/dovecot/libdovecot-storage.so.0(maildir_storage_sync_init+0xb5) [0x7f43340bef35] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_sync_init+0x2b) [0x7f43340cc405] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_sync+0x27) [0x7f43340cc4f1] -> /usr/lib64/dovecot/libdovecot-storage.so.0(index_storage_get_status+0x2f) [0x7f43340f1f6a] -> /usr/lib64/dovecot/lib01_acl_plugin.so(+0xdff9) [0x7f43335ffff9] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_get_status+0x31) [0x7f43340cd36c] -> dovecot/imap(imap_status_get+0x5f) [0x41dc1d] -> dovecot/imap() [0x410cf9] -> dovecot/imap(cmd_list_full+0x49d) [0x411297] -> dovecot/imap(command_exec+0x37) [0x417f20] -> dovecot/imap() [0x4170c9] -> dovecot/imap() [0x417174] -> dovecot/imap(client_handle_input+0x106) [0x417400] -> dovecot/imap(client_input+0x72) [0x417768] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x3f) [0x7f4333e13536] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0xd1) [0x7f4333e142e6] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x9) [0x7f4333e13598] Sep 18 12:46:02 HOST dovecot: imap(USER): Fatal: master: service(imap): child 32253 killed with signal 6 (core dumps disabled) ---8<----

Oops, I guess I was too much in a hurry to even compile it. Here's a new patch that compiles and passes our director CI tests.

Using both starttls and ssl in passdb on proxy results in timeouts
by Filias Heidt 18 Sep '18

Hi List, I have a dovecot which proxies to different backends depending on an entry in a mysql-database. The mysql-query sets ‚ssl‘ to ‚any-cert‘ and this works fine. But this causes me a problem: sieve-backends only support STARTTLS and if I set ‚ssl‘ to ‚any-cert‘ (or yes), it will attempt a TLS-connection to the sieve-backends, which fails. My attempt was to alter the query to include %{real_lport} and return ‚ssl=no‘ and ‚starttls=any-cert‘ if the port matches the sieve-port. It works as expected in that it returns the correct values and proxies to the correct backend. However it seems that TLS is no longer working and I get timeouts from the backends. Debug: client passdb out: OK 1 user=someuser(a)example.com proxy proxy_nopipelining=y host=backend1.example.com nodelay=y nologin starttls=no ssl=any-cert hostip=so.me.i.p pass=<hidden> results in: Sep 17 11:08:47 imapproxy1 dovecot: imap-login: Error: proxy(someuser(a)example.com): Login for so.me.i.p:993 timed out in state=/none (after 30 secs, local=lo.cal.i.p:60524): user=<someuser(a)example.com>, method=PLAIN, rip=re.mo.te.ip, lip=lo.cal.i.p, TLS, session=<OySXgw12auwgARYIAAYABwAAAAAAAwAU> My query looks like this: password_query = SELECT host from proxy_domain, NULL as password, 'y' as nopassword, 'y' as proxy, NULL as destuser, 'y' as proxy_nopipelining, 'y' as nodelay, 'y' as nologin, IF(%{real_lport}=4190, 'any-cert', 'no') as 'starttls', IF(%{real_lport}<>4190, 'any-cert', 'no') as 'ssl‘; As soon as I remove the starttls-part and the passdb only returns ssl=any-cert (without starttls=no) it works flawlessly. Is it possible that I am attacking the problem the wrong way? Or is it not possible to set both starttls and ssl to some values in passdb and enable/disable them as needed? Thanks for any input :) Cheers, Filias
