Apple mail fails with Submission
by Ruud Voorjans 08 Jan '19

08 Jan '19

Dear all, I'm running dovecot # 2.3.2.1 - Pigeonhole version 0.5.2 () - OS: Linux 4.18.0-12-generic x86_64 Ubuntu 18.10 with Submission. It works great except with apple mail (Iphone). I get an error with the MTA (postfix): ""postfix/submission/smtpd[32552]: warning: non-SMTP command from mail.example.org[xx.xx.xx.xx]: Content-Transfer-Encoding: 7bit"" with other mail-client(s) (Outlook (Desktop and Iphone app)) i have no problem and it proxy-sends the e-mail beautiful out to the recipient. I think it is some kind of bug or maybe it just isn't supported (yet), cause as you said it is still "pretty basic". Best Regards

Fwd: Re: gcc -> clang

The compiler returns many warnings, and the test returns two IPv6-related errors.

doveadm + HA
by Maciej Milaszewski IQ PL 07 Jan '19

07 Jan '19

Hi I have two server directors in ring and 5 dovecot servers (2.2.36) IP for IMAP and POP3 is a VIP (keepalived) What is the best solutions to get realy HA for 5 dovecot servers ? Maby corosync+pacemeker ? But this solution is too problematic and hardcore Why I need HA ? Doveadmin is too lazy and doveadm director does not know that one machine broke down and still sends traffic

Dovecot no logs by sieve user script
by Christian Wolf 07 Jan '19

07 Jan '19

Dear mailinglist, I have the problem that I had to migrate a setup and since then my user's sieve script does no longer log anything. I have sieve_user_log unset and sieve points to a folder (ready for ManageSievev service). In the old config I had sieve point to the symlink and sieve_dir point to the folder of all scripts. As sieve_dir is deprecated I use the sieve directive only (see below). According to my understanding of https://wiki2.dovecot.org/Pigeonhole/Sieve/ Configuration this should result in user logging in ~/.dovecot.sieve.log. This file is never generated by dovecot and if I create it manually, it is not filled. Can you tell me, what I am missing here in order to get the per-user logs running? Thank you very much Christian # dovecot --version # dovecot -n # 2.2.27 (c0f36b0): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.16 (fed8554) # OS: Linux 4.9.0-8-amd64 x86_64 Debian 9.6 auth_mechanisms = plain login disable_plaintext_auth = no mail_location = maildir:~/Mailbox 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 = mailbox Drafts { auto = create special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } passdb { args = scheme=CRYPT username_format=%u /etc/dovecot/users driver = passwd-file } plugin { sieve = file:~/sieve;active=~/.dovecot.sieve } postmaster_address = postmaster@wolf- stuttgart.net protocols = " imap sieve sieve" service auth { unix_listener /var/spool/postfix/ private/auth { mode = 0666 } } service managesieve-login { inet_listener sieve { port = 4190 } } ssl = required ssl_cert = </etc/letsencrypt/live/imap/fullchain.pem ssl_key = # hidden, use -P to show it userdb { driver = passwd } userdb { args = username_format=%u /etc/dovecot/users driver = passwd-file } protocol lda { mail_plugins = " sieve" }

special_use folders still created
by Marc Roos 07 Jan '19

07 Jan '19

dovecot-2.2.36-3.el7.x86_64 The below configuration seems to work for Thunderbird and emclient, when moving a message to Junk. Emclient uses "Junk E-mail" and Thunderbird uses "Junk". On the server is only the file .Junk created as expected. When I move a message to Archive in Thunderbird. On the server the files .Archives and .Archives.2018 are created (Thunderbird creates a subfolder in Archives) How is this possible? On the server there is already an .Archive folder so it should create .Archive.2018 not? imap_capability = +SPECIAL-USE # drafts folders merging mailbox Drafts { special_use = \Drafts auto = create } # archive folders merging mailbox Archive { special_use = \Archive auto = create } mailbox Archives { special_use = \Archive auto = no } # spam folders merging mailbox Junk { special_use = \Junk auto = create } mailbox Spam { special_use = \Junk auto = no } mailbox "Junk E-mail" { special_use = \Junk auto = no }

reprocessing mail
by Marc Lucke 06 Jan '19

06 Jan '19

Hey guys, I had some corruptions whereby dovecot would bomb out on mail files in my maildir. I found that if piped the files to dovecot-lda the all email was clean &lost. I even retrieved email I thought might have been lost for good. I have some better ideas now, but I still processed a few thousand emails like that now & would like to do something like this: * stop dovecot * iterate over each file ** get date ** touch date (linux - to set the date/time) ** rename the file with the correct epoch ** update dovecot-uidlist with correct epoch * start dovecot Will that work? Or is there something I've missed or should do? - Marc

Sieve "OOO" configuration
by Jerry 05 Jan '19

05 Jan '19

I am able to get sieve issuing an "out of office"message correctly. However, I want to configure it to send an "OOO" message only during certain dates, say on weekends, or only between certain hours. I can do that manually; however, was wondering if there is any automatic method available that could handle this chore. Thanks! -- Jerry

I figured out they might accidentally be compressed twice - they are. How could this happen? I used this script: dovecot-maildir-compress.sh (https://gist.github.com/cviebrock/e37f80a3223dfee19051c936c5ebe509) which appends an additional flag 'Z' after processing/conmpressong the mail and only compresses those without the flag: > find=$(find "$maildir" -type f -name "*,S=*" -mtime +30 ! -name "*,*:2,*,*Z*" -printf "%f\n") ... > if echo $flags | grep ','; > then > newname=$filename"Z" > else > newname=$filename",Z" which is actually neat. Now two possible things: (1) I am not quite sure yet but my best guess is that moving messages from one folder to another (via mail client) the message looses it's 'Z' flag. (2) compressing might have failed to rename but successfully compressed the file and the another consecutive run of the script compressed the file again. How could I recursively (a) check each maildir file if e.g. the output of(zcat $file | zcat) is ASCII or !binary (b) find all mails which are compressed - i.e. valid gzip - but miss the 'Z' flag ? (c) find all mails that are valid gzip but dont contain ASCII if / dont uncompress to mail ? There are backups in place for all files I get a error for, but I want to recursively fix the problem. Any hint? Thanks in advance! -M -- info(a)awib.it

Searching small(ish) sites on ubuntu
by Dirk Koopman 05 Jan '19

05 Jan '19

I run a small dovecot site with ~5 users, some of whom have many large mailboxes. I used to use lucene until the packagers decided that it broke some licencing rules and stopped including it. I have dismally failed to configure Solr, plus it is huge and potentially exposes too many services as well. Squash is deprecated (but still used?) in 2.2+. I am currently on 2.2.33. So what can I use? Or do I have to bite the bullet and install from source, thus losing the advantages of packaging and automatic updates? Dirk

Please, use clang instead of gcc. Code quality can only profit from it. I just compiled 2.3.4 and compiler stderr is full of interesting problems.

Moving Alternate Storage to another disk.
by bOnK 03 Jan '19

03 Jan '19

Hello, Dovecot 2.3.4_3 on FreeBSD 11.2. I am using mdbox Alternate Storage since about two years without any problems. However, the disk containing this storage is almost full and I have to move this data to another disk, probably zpool. Would it be okay to do the following? 1) Shut down dovecot (and mail server) so no new mail comes in. 2) Copy/move all files in ALT location to new disk, using shell commands like cp/mv/cpdup. 3) Change the path to ALT in dovecot-conf mail_location. 4) Change the 'dbox-alt-root' soft-links in each users main (INBOX) directory to point to this new location. 5) Start up dovecot and mail server. Am I missing something or maybe there is a better way? -- Thanks, and have a nice new year. bOnK

Sieve script unable to file into public folder after dovecot upgrade to version 2.3.4
by Andreas Oster 03 Jan '19

03 Jan '19

Hi all, Wishing you and your families a Happy New Year 2019. I am currently struggling with an odd sieve issue after upgrading dovecot from 2.2.32 to the latest 2.3.4 version. OS is Ubuntu 18.04. For one of our users I have a sieve rule in place which should copy (keep + fileinto) incoming mails from the INBOX to a public namespace folder. Unfortunately this does not work anymore. In the sieve log file of the user I get error messages like this: sieve: info: started log at Jan 02 12:41:31. error: msgid=<dc6bdcb2-7efb-0f0a-3a6d-c1133233c11f(a)novanetwork.de>: failed to store into mailbox 'Public/Verteiler': Permission denied. This is the content of the sieve script : require ["fileinto"]; keep; fileinto "Public/Verteiler"; stop; At first I thought it might be caused by a faulty IMAP ACL but this does not seem to be the case. When I do a manual copy in Thunderbird from the INBOX to this public folder there are no problems at all. Does anybody have an idea what could be the cause of the issue ? Thank you very much for your kind help. Best regards Andreas

dovecot-uidlist path
by Christos Chatzaras 02 Jan '19

When I use this: mail_location = maildir:/home/mail/%d/%n the dovecot-uidlist file is located in: /home/mail/example.com/user/dovecot-uidlist But when I change it to: mail_location = maildir:/home/mail/%d/%n:CONTROL=/var/mail/%d/%n then it's stored in: /var/mail/example.com/user/.INBOX/dovecot-uidlist Any idea why is not stored in: /var/mail/example.com/user/dovecot-uidlist ?

Error with virtual index "Broken mailbox_count header"
by Tobias Kirchhofer 02 Jan '19

02 Jan '19

Hi, we experience trouble with one of our virtual mailboxes. dovecot-virtual: ` * -INBOX/Trash -INBOX/Spam all ` Error log: ```Error: virtual index /var/vmail/mailboxes/kirchhofer.net/tobias/virtual/all: Broken mailbox_count header``` This happens only with the filter form above. All other virtual mailboxes works fine. Jakobus Schürz experienced something similar: https://www.dovecot.org/list/dovecot/2018-January/110656.html We do not have the panic message. Is this probably something on our side or is this Dovecot? ``` namespace virtual { prefix = Virtual/ separator = / location = virtual:~/virtual } -- collect(a)shift.agency

I had this previous installation working, with LD_LIBRARY_PATH configured, on solaris 10 u8 since 2014. During this relativelly calm period I did a LiveUpgrade to latest solaris 10 ( u11 ) and the only application that stopped working is dovecot. This mean that ( obviously ) solaris changed something on security. No binary is setuid or setgid in dovecot dir: ls -l /usr/local/dovecot/sbin/dovecot -rwxr-xr-x 1 root root 259452 Dec 29 14:59 /usr/local/dovecot/sbin/dovecot root@puma find . -perm 4000 root@puma find . -perm 2000 root@puma find . -perm 1000 but yes, I agree that eventually the SRL stuffs could make them job. Probably is not tied to the setuid/setgid but with the fork of a binary from inside another one with the LD_LIBRARY_PATH in use. Thus the option is ( could be ) to use the R[UN]PATH feature or the wrapper with the new LD_LIBRARY_PATH ( as I'm doing now altough less secure ) or recompile with the -R option passed to linker, as suggested by James ( and verified to be working at least with the "dump" ).

Several problems on Solaris10
by Pierluigi Frullani 01 Jan '19

01 Jan '19

Hi all, I've just upgraded my old Solaris 10 update 8 to Solaris 10 update 11 with the latest patches, but after the reboot with the new update I'm having a lot of problems with dovecot. My version is 2.2.13 ( it was the last one, at the time of the first server setup ). I have seen that ( it seems ) the new solaris don't honour the LD_LIBRARY_PATH. The first error was a relocation error: relocation error: file /usr/local/dovecot/lib/dovecot/libdovecot-login.so.0: symbol EVP_PKEY_get1_EC_KEY: referenced symbol not found Just to bypass this phase I have linked the openssl-1.0.1e in /usr/local/lib ( libssl and libcrypto ) but then I got a new relocation error: imap: Error: dlopen(/usr/local/dovecot/lib/dovecot/lib20_fts_plugin.so) failed: ld.so.1: imap: fatal: relocation error: file /usr/local/dovecot/lib/dovecot/lib20_fts_plugin.so: symbol http_url_parse: referenced symbol not found Did someone has some idea on how to bypass those troubles ? Thanks in advance Pierluigi

BUG mailboxaliases, does not take into account namespaces

Does not honour namespaces. Should at least get the namespace location and link to that location and not just created a folder and link to it in the main/top? Namespace.

BUG mailboxaliases plugin not working with subfolders
by Marc Roos 30 Dec '18

30 Dec '18

The mailboxalias plugin is not working when subfolders are created, rendering its use quite useless. It should work of course something like this. (then I would be able eg. to put my archive mailboxes on different storage, by just creating one symlink on archive (get it??;)) If there is a new mailbox created And in its path there is a folder/path configured in aliases plugin Get the original folder location of that symlink Create a new file with the original name + new subfolder name, in the same location as the parent And then create a symlink to that created file with Thus not this mailbox_alias_old8 = Archive mailbox_alias_new8 = Archived messages -rw------- 1 xxx xxx 0 Dec 30 15:36 .Archive lrwxrwxrwx 1 xxx xxx 8 Dec 30 15:36 .Archived messages -> .Archive -rw------- 1 xxx xxx 0 Dec 30 15:40 .Archived messages.am-test But this: -rw------- 1 xxx xxx 0 Dec 30 15:36 .Archive lrwxrwxrwx 1 xxx xxx 8 Dec 30 15:36 .Archived messages -> .Archive -rw------- 1 xxx xxx 0 Dec 30 15:40 .Archive.am-test lrwxrwxrwx 1 xxx xxx 8 Dec 30 15:36 .Archived messages.am-test -> .Archive.am-test And then if you fix this, you might aswell take this into account. Thus in case I already have a symlink on .Archive -rw------- 1 xxx xxx 0 Dec 30 15:36 .Archive -> /home/mail-archive/userx/.Archive lrwxrwxrwx 1 xxx xxx 8 Dec 30 15:36 .Archived messages -> /home/mail-archive/userx/.Archive lrwxrwxrwx 1 xxx xxx 8 Dec 30 15:36 .Archived messages.am-test -> /home/mail-archive/userx/.Archive.am-test Then your mailboxaliases plugin starts to make sense a bit, now it is not consistent in its naming and is only creating a mess.

Archive namespace accepting messages to the main folder
by Marc Roos 29 Dec '18

29 Dec '18

I am struggling with an archive namespace. I am not sure if this is can solved. But if you right click in apple mail on a message and choose archive. It wants to move the message to the folder Archive folder (marked in the attached). If I set inbox=yes it is possible to move the mail in this folder, but then I get other problems (two namespaces with inbox=yes). When I leave it inbox=no, I get a complaint of apple mail that the mailbox is not selectable (attachment) namespace { type = private separator = / prefix = Archive/ location = mbox:/home/mail-archive/%u/Archive/:CONTROL=/home/mail-archive/%u/Archiv e/control:INDEX=/home/mail-archive/%u/Archive/index:LAYOUT=maildir++ inbox = no hidden = no list = yes subscriptions = yes } PS.

Problem with different certificates
by Andreas Meyer 27 Dec '18

27 Dec '18

Hello! Dovecot manages different domains. Today I renewed the certifiactes from letsencrypt and since that time, dovecot does not recognized the certs for different domains anymore: This is part of my config: ssl = yes ssl_cert = < /etc/letsencrypt/live/bitcorner.de/fullchain.pem ssl_key = < /etc/letsencrypt/live/bitcorner.de/privkey.pem local 37.120.166.21 { # instead of IP you can also use hostname, which will be resolved protocol imap { ssl_cert = < /etc/letsencrypt/live/bitcorner.de/fullchain.pem ssl_key = < /etc/letsencrypt/live/bitcorner.de/privkey.pem } } local 46.38.231.143 { protocol imap { ssl_cert = < /etc/letsencrypt/live/nimmini.de/fullchain.pem ssl_key = < /etc/letsencrypt/live/nimmini.de/privkey.pem } } This worked for years and I don't know what's wrong now. It seems dovecot just takes the default certs into account and ignores the certs defined with "local" completly. Any help appreciated. Kind regards Andreas -- PGP-Fingerprint: F004 8EEE 5E54 F2EA 566E B939 22E5 85DD AA14 AC0A

Re: Errors with missing links to files when using Single Instance Storage and zlib (Dovecot 2.3.4)
by Daniel Schütze 27 Dec '18

27 Dec '18

Having had a week with the system I'm now inclined to believe that the issues I've seen are not necessarily related to SIS and zlib but may be due to replication instead. After experiencing these issues and looking at historical mailing list posts I wrote a basic script (as was suggested as a possible diagnostic approach for SIS before SIS was even implemented!) which pulled all the mail from a user doveadm fetch -u username body all > /dev/null 2>error.log This generated errors in error.log for every e-mail with a problem. From that and some use of sed,uniq,cut and ln I was able to (re)create the missing links. Unfortunately the error generated was only the first missing link for all the links expected for an e-mail. So my script had to be run multiple times per user until no more errors were reported. This wasn't all that onerous given I was basically running on a test box before mass migrating my users. A better approach would have been to scan the mdbox files for all links expected and check the existence of them all. Having (re)created all missing links I've not had a single instance of a link being missing after a week of delivery of mail (where the errors were regular before this procedure). I have also since looked at how replication handles links. What I hadn't expected was that the links created on the server pair are not the same. Although I had two servers which started in the same state (one a clone of the other) after a month or so of replication they had diverged to the state where if I sent a test message to the one server I could see the file name of the link created to the has was not the same on both servers (although obviously the hash itself was the same name and content wise). This leads me to believe the errors I saw where most likely down to my expecting the two servers in the pair to have identical SIS attachment directories/hardlinks to hashes and the way I handled my migration. Coming from a database mail server were replication master/slave means the backend should be absolutely identical if all is working I may simply have gotten the wrong idea of dovecot replication. With my 2.3.1 and 2.3.4 replication pair there were a lot of the tcp errors which the changelog for Dovecot stated had been fixed post 2.3.1; mainly the connection timing out after 10 minutes. Looking at the code for replication (which I'm not going to claim I've fully go to grips with) it looks like the name of a hardlink is made up of essentially [hash]-[identifier including mailbox GUID]. It must be the case then that the [identifier including mailbox GUID] can diverge between server pairs, at least with 2.3.1 as a version involved.

I am running Dovecot 2.3.4 on FreeBSD11.2 and I did not see this error on Dovecot 2.3.1 FreeBSD 10.4. Both installs had the same configuration for Dovecot. Both installs were made from source code and not packages (as the need for the non standard fts and mysql options). During my testing I had the 2.3.1 install receive mail and replicate to the 2.3.4 and that was working fine (except for tcp connection issues which I saw was fixed in the changelog). Unfortunately having gone into testing with real account and mail being sent to the 2.3.4 install I'm seeing the above errors. My clients are using Thunderbird on desktops and Roundcube for webmail. My users report they can see the e-mails fine in their webmail (Roundcube) and only Thunderbird is giving issues. I admit I don't know how this can be the case as both systems use the same account details. In everycase so far there is a file in the hashes directory I have hand crafted the missing file (i.e. link) using ln and this restores access in Thunderbird. Clearly this is an big issue for my install and I'd appreciate any help! At the moment it looks like my course will be to try and script creation (recreation?) of the links from the error logs (I've seen people talking about this online) but that isn't really what I'm after.

Migration to 2.3.36 using replication
by Thomas Durand 26 Dec '18

26 Dec '18

Hello, I have to migrate my dovecot box to a new one. I would like to know if it’s possible to do this migration with the replication process. My plan is to activate replication between 2.2.10 server and the 2.3.4 new server. Then I will update the DNS to redirect the name to new box. Users will then connect either on the new or the old box depending on the dns upgrade. Does anyone have already experienced such process ? Is there any incompatibility issue ? Thanks. Thomas

Heads-up regarding non-replication of Sieve scripts?
by Markus Ueberall 25 Dec '18

25 Dec '18

Dear all, A couple of months ago, it has been mentioned that multiple users experienced a problem regarding the synchronisation of Sieve scripts by means of "dsync" (whereas e-mails were replicated just fine between servers) [1][2] for Dovecot v2.3.x; the same problem apparently occurred with early versions from the v2.2 branch some three years ago but has been marked/confirmed as fixed back then [3]. Since I'm currently using the 2.2.33.2[-1ubuntu3] packages from the Dovecot community software repository and would like to upgrade to v2.3.x at one point, I'm very interested in hearing whether the above problems have been fixed (if so, how?) since I do not want to semi-manually synchronise the Sieve scripts between two mail servers in active/active mode on my own. Thanks in advance for a heads-up / Kind regards, Markus [1] https://www.dovecot.org/pipermail/dovecot/2018-October/113244.html [2] https://www.dovecot.org/pipermail/dovecot/2018-August/112548.html [3] https://www.dovecot.org/pipermail/dovecot/2015-February/099658.html

Password expiration: how to trigger it?
by Cédric Jeanneret 21 Dec '18

21 Dec '18

Dear Dovecot Team, I'm in the (long) process of migrating my whole email infrastructure. Of course, dovecot is in the place, and is working just fine. Still, I have an issue: password expiration. I'm now using FreeIPA backend for the user authentication, and it includes the capacity to expire passwords. Basically, it's an LDAP with fancy things, among them a field named krbPasswordExpiration (yes, that's kerberos). In order to make things simple, I'd rather NOT force my users to set up a kerberos/gssapi/whatever on their personal computer (most of them will just have blank gaze if I start talking about that). Is there a way to make Dovecot use that field? It's apparently a simple date in %Y%M%D%H%m%sZ format, so a pretty neat thing to test. If there's some support for that in Dovecot, that is. If not, as a last resort, I can configure the freeIPA to deactivate the user if the password is expired, and this should push another field in the user description. Would that be a possibility for Dovecot, in case it can't use the datetime field as is? Thank you for your support! Cheers, C.

outlook idiocy - IMAP folders with /
by Wojciech Puchar 20 Dec '18

20 Dec '18

user attempts to create folders with / dovecot naturally cannot create it so it returns error but outlook of course "create" it and keep data in local store only. data is lost when you remove local store .pst file. The question is - can dovecot be configured so it will automatically replace slash in name with something else?

SIS feature request
by Daniel Miller 20 Dec '18

20 Dec '18

I tried SIS a couple years ago - I was very excited with the resulting decrease in storage requirements but the undiagnosed intermittent issues became too significant to ignore so I switched away. Recently I was thinking about it again. The primary issue with SIS seemed to be links would be deleted even though the source attachment files and related mails still existed. It was possible to either manually re-build the links or have a script scan the mail error log and perform such. I haven't looked at the code - but a thought for a possible "temporary" fix: 1. Whatever function in dbox code that performs the deletion of links - prior to actually deleting call a new function that will verify if any mails exist that reference it. A new function, without modifying existing code, may catch something the existing functions don't - and if it logs the fact that it was called and found something...perhaps we can find the flaw in the original algorithm. Just a thought. 2. In the mail retrieval function, if the attachment link doesn't exist - perform the relevant scan through the attachment database and if found re-create the link automatically. This should log an error but indicate the recovery. -- Daniel

Hi list! For some reason I need to use a really weak server key (256 bit) with dovecot for imaps access. Is this possible? I tried but getting this error: dovecot: imap-login: Error: SSL: Stacked error: error:04075070:rsa routines:RSA_sign:digest too big for rsa key This is on an Ubuntu 14.04 on x64. Thank you! Stavros

High Load average on NFS Spool - v.2.1.15 & 2.2.13
by Albert E. Whale, CEH CHS CISA CISSP 19 Dec '18

I have two servers pointing to an NFS mounted mail spool with dovecot. Since I recently switched from using Dovecot v1.X, I have been experiencing high CPU use with the two Dovecot servers. I am not certain why they are not well behaved. Here is the configuration information. This configuration is currently running at a load average of 17. /usr/sbin/dovecot -n # 2.1.15: /etc/dovecot/dovecot.conf # OS: Linux 3.10.54-server-2.mga3 i686 Mageia 3 base_dir = /var/run/dovecot/ disable_plaintext_auth = no lock_method = dotlock login_greeting = SpamZapper Email ready. login_log_format_elements = user=<%u> method=%m rip=%r lip=%l %c mail_debug = yes mail_fsync = always mail_location = maildir:~/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_privileged_group = mail mbox_lock_timeout = 15 mins mmap_disable = yes passdb { driver = pam } protocols = imap pop3 service anvil { client_limit = 203 process_limit = 1 } service auth { user = root } service imap-login { chroot = login client_limit = 10 user = dovecot vsz_limit = 256 M } service pop3-login { chroot = login client_limit = 20 user = dovecot } ssl = no syslog_facility = local2 userdb { driver = passwd } verbose_proctitle = yes protocol pop3 { mail_max_userip_connections = 20 pop3_logout_format = top=%t/%p, retr=%r/%b, del=%d/%m, size=%s pop3_uidl_format = %08Xv%08Xu } protocol lda { postmaster_address = postmaster(a)example.com } protocol imap { mail_max_userip_connections = 10 } And the other server which is currently running with a load average of 10. dovecot -n # 2.2.13: /etc/dovecot/dovecot.conf doveconf: Warning: service anvil { client_limit=100 } is lower than required under max. load (303) # OS: Linux 4.1.15-server-2.mga5 x86_64 Mageia 4 base_dir = /var/run/dovecot/ disable_plaintext_auth = no listen = * lock_method = dotlock login_greeting = SpamZapper Email ready. login_log_format_elements = user=<%u> method=%m rip=%r lip=%l %c mail_fsync = always mail_location = maildir:~/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_privileged_group = mail mmap_disable = yes passdb { driver = pam } protocols = imap pop3 service anvil { client_limit = 100 process_limit = 1 } service auth { user = root } service imap-login { chroot = login client_limit = 48 user = dovecot vsz_limit = 256 M } service pop3-login { chroot = login client_limit = 50 user = dovecot } ssl = no syslog_facility = local2 userdb { driver = passwd } verbose_proctitle = yes protocol pop3 { mail_max_userip_connections = 50 pop3_logout_format = top=%t/%p, retr=%r/%b, del=%d/%m, size=%s pop3_uidl_format = %08Xv%08Xu } protocol lda { postmaster_address = postmaster(a)example.com } protocol imap { mail_max_userip_connections = 40 } Can you please offer a suggestion on what is happening?

Re: How to configure Dovecot to disable NIST's curves and still rertain EECDH?
by Kurt Fitzner 19 Dec '18

19 Dec '18

My opinion is that security by RFC is not security, it's mommy medicine. Standards have had a terrible time keeping up with security realities. NITS's curves leak side channel information all over the place. I don't have details on what implementations are set to calculate the NIST curves in constant time, and that's not an easy feat to do anyway so I don't want to depend on implementations that say they are actually doing it the right way. Frankly I can't be bothered to keep up with that. There are better curves TODAY, so yes I intend to use them if I can find a way. Otherwise, I'll just keep EECDH disabled. I have EDH now, and I've not yet run into a client that doesn't support it. I want EECDH, but I won't use it without safe curves. I'm confident that EECDH with safe curves and a second choice of EDH will support any clients that are worth using. OpenSSL supports X25519, and that is half the battle. Is there a way to change the curve selection in Dovecot?

How to configure Dovecot to disable NIST's curves and still rertain EECDH?
by Kurt Fitzner 19 Dec '18

19 Dec '18

I am interested in configuring Dovecot's TLS so as to retain forward secrecy, but eliminate all of NIST's elliptic curves. Besides being subject to side channel attacks [1], in some quarters there is a general distrust of NIST's curves and any of their other cryptographic primitives after the Dual EC DRBG debacle. >From what I can tell, the following will prevent the use of NIST's curves (along with other dangerous primitives) in Dovecot, but this is accomplished by simply disabling EECDH entirely. ssl_cipher_list = HIGH:!DSS:!EECDH:!ECDH:!SHA1:!aNULL:!eNULL:@STRENGTH This should still retain forward secrecy through the use of EDH, but this doesn't leave much in the way of allowable algorithms on my server: $ openssl ciphers -V 'HIGH:!DSS:!EECDH:!ECDH:!SHA1:!aNULL:!eNULL:@STRENGTH' 0x00,0x9F - DHE-RSA-AES256-GCM-SHA384 TLSv1.2 Kx=DH Au=RSA Enc=AESGCM(256) Mac=AEAD 0x00,0x6B - DHE-RSA-AES256-SHA256 TLSv1.2 Kx=DH Au=RSA Enc=AES(256) Mac=SHA256 0x00,0x9D - AES256-GCM-SHA384 TLSv1.2 Kx=RSA Au=RSA Enc=AESGCM(256) Mac=AEAD 0x00,0x3D - AES256-SHA256 TLSv1.2 Kx=RSA Au=RSA Enc=AES(256) Mac=SHA256 0x00,0x9E - DHE-RSA-AES128-GCM-SHA256 TLSv1.2 Kx=DH Au=RSA Enc=AESGCM(128) Mac=AEAD 0x00,0x67 - DHE-RSA-AES128-SHA256 TLSv1.2 Kx=DH Au=RSA Enc=AES(128) Mac=SHA256 0x00,0x9C - AES128-GCM-SHA256 TLSv1.2 Kx=RSA Au=RSA Enc=AESGCM(128) Mac=AEAD 0x00,0x3C - AES128-SHA256 TLSv1.2 Kx=RSA Au=RSA Enc=AES(128) Mac=SHA256 Is there a better way to do this? Is there a way to disable only the suspect NIST curves and still retain EECDH but with side-channel safe curves like X25519?

Errors with missing links to files when using Single Instance Storage and zlib (Dovecot 2.3.4)
by Daniel Schütze 18 Dec '18

18 Dec '18

I'm running Dovecot 2.3.4 with Single Instance Storage (SIS) and zlib and I am frequently seeing errors where files are missing in the attachments directory even though the zipped file in the hash directory is actually there. This appears not to have been an issue in Dovecot 2.3.1 Requested output of the server below. The error looks like this in the log Dec 18 08:58:58 dovecot01 dovecot: imap(username)<3692><RKnPGEh9fC3AqAAB>: Error: Mailbox INBOX/FOLDER: UID=41: read(attachments-connector(zlib(/usr/home/vmail/mail/username//mdbox/storage/m.411))) failed: read(/usr/home/vmail/attachments/91/08/91085773a0774909207852b8f9c98dbe22fe5a31-e88ba0276aae135cd2050000d09efc50[base64:19 b/l]) failed: open(/usr/home/vmail/attachments/91/08/91085773a0774909207852b8f9c98dbe22fe5a31-e88ba0276aae135cd2050000d09efc50) failed: No such file or directory (FETCH BODY[]) I'm also seeing errors when replication fails dovecot: dsync-local(username)<bzg3MqjhGFxmFwAAzRvpBw>: Error: dsync(servername): read(attachments-connector(zlib(/usr/home/vmail/mail/username//mdbox/storage/m.413))) failed: read(/usr/home/vmail/attachments/45/42/4542dcf385f6b4a4dc8752b96db1d7ad8a8023d5-ac735007f6bd135c93440100cd1be907[base64:19 b/l]) failed: open(/usr/home/vmail/attachments/45/42/4542dcf385f6b4a4dc8752b96db1d7ad8a8023d5-ac735007f6bd135c93440100cd1be907) failed: No such file or directory (last sent=mail, last recv=mail (EOL)) It is not the case that every replication fail has a corresponding imap access fail. I am running Dovecot 2.3.4 on FreeBSD11.2 and I did not see this error on Dovecot 2.3.1 FreeBSD 10.4. Both installs had the same configuration for Dovecot. Both installs were made from source code and not packages (as the need for the non standard fts and mysql options). During my testing I had the 2.3.1 install receive mail and replicate to the 2.3.4 and that was working fine (except for tcp connection issues which I saw was fixed in the changelog). Unfortunately having gone into testing with real account and mail being sent to the 2.3.4 install I'm seeing the above errors. My clients are using Thunderbird on desktops and Roundcube for webmail. My users report they can see the e-mails fine in their webmail (Roundcube) and only Thunderbird is giving issues. I admit I don't know how this can be the case as both systems use the same account details. In everycase so far there is a file in the hashes directory I have hand crafted the missing file (i.e. link) using ln and this restores access in Thunderbird.

Change default mode for attachment files
by Олег Кривоносов 18 Dec '18

18 Dec '18

Hi I migrated my dovecot server from Maildir to mdbox with saving attachments to external files and enabled SIS a few days ago. Everything works fine except one issue. I have both virtual and system users. Dovecot saves attachments with mode 0600. So I catch such errors for system users: dovecot: lda(wasya): Error: fs-sis: Couldn't read hash file /var/mail/attachments/2e/dc/hashes/2edc6009bc9b6ba38febb581df03986dcaf134d9: Permission denied I want to fix this issue by changing default file mode to 0660 via group policy. I found such feature in the changelog (v2.1.rc2 2012-01-06): lib-fs: Added "mode" parameter to "posix" backend to specify mode for created files/dirs. Unfortunately I can't find any information about this feature in the dovecot documentation. Can I use it to setup mode 0660 for attachments in the dovecot configuration? uname -a Linux diplo.trueconf.ru 4.9.0-6-amd64 #1 SMP Debian 4.9.88-1+deb9u1 (2018-05-07) x86_64 GNU/Linux dovecot --version 2.2.27 (c0f36b0) 10-mail.conf dovecot configuration: mail_access_groups = vmail mail_location = mdbox:~/mdbox mdbox_preallocate_space = yes mdbox_rotate_interval = 1 weeks mdbox_rotate_size = 5 M mail_attachment_dir = /var/mail/attachments mail_attachment_min_size = 32k mail_attachment_fs = sis posix mail_attachment_hash = %{sha1} Thank you

But reading that fts_solr message, and some other comments, leads me to wonder - could this be caused by someone/thing trying to authenticate as root? On that theory - I tried doing so via telnet - and received: Dec 17 15:06:02 bubba dovecot: auth: Error: plain(ultradeitytypeperson(a)amfes.com,127.0.0.1,<4kQr0z99UMZ/AAAB>): user not found from any userdbs Dec 17 15:06:02 bubba dovecot: imap: Error: Authenticated user not found from userdb, auth lookup id=3522297857 (auth connected 1 msecs ago, handshake 0 msecs ago, request took 1 msecs, client-pid=29572 client-id=1) I have root's email aliased to a valid user's email. I'm not sure how I'm able to authenticate as root - there isn't a root user defined in my LDAP database and that should be the only auth backend enabled for Dovecot. Or do I need to explicitly block local users from /etc/passwd on the server? The only auth databases shown in doveconf -n: userdb { driver = prefetch } userdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } passdb { args = /usr/local/etc/dovecot/master-users driver = passwd-file master = yes } passdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } and "master-users" doesn't list root either. -- Daniel

We don't replace phones just because new versions are available, we replace them when they stop working, and when we do we usually get refurbished because we hate how much electronic waste is in the world. I have to admit, the tin foil hat of mine just got an alert. We know there are unexplained constants in the NIST curves including P-256 - what if NSA was partially responsible for this bug (back room deal to avoid anti-trust prosecution, similar deal with IBM was made in the 70s I believe also involving cryptography) so that Android apps that use ECDSA (beyond just the mail client, e.g. chat apps) would use P-256 for compatibility and are maybe vulnerable to MITM for the key exchange.

Overrideing pop delete?

17 Dec '18

Is it possible to override the POP3 delete on download command and make sure that messages stay on the server for at least X hours or X days? It is important that the messages be around long enough to hit a snapshot cycle (using rsnapshot to backup ever hour). -- Greedo didn't shoot first, motherfucker!

Bug in IDLE implementation for virtual mailbox
by Pali Rohár 17 Dec '18

17 Dec '18

Hello! I found bug in Dovecot's IDLE implementation when virtual mailbox is in use. IDLE does not notify about new emails when email appears in newly created mailbox and IDLE was issued in virtual folder which matches "*" wildcard and that mailbox was created after opening virtual mailbox. This problem is present in version 2.2.34 which is available in Debian Stretch system with backports. Reproducer: 1. Create virtual "All" mailbox in Gmail-like style: $ cat All/dovecot-virtual * -Drafts -Spam -Trash ALL 2. Ensure that (real non-virtual) mailbox "Test" does not exist. 3. Create sieve rule which deliver some email to "Test" mailbox. require [ "fileinto", "mailbox" ]; ... fileinto :create "Test"; 4. Open dovecot imap connection, select virtual "All" mailbox and then enter IDLE command. 4. Send email which matches that sieve filter. Email will be processed by dovecot sieve. As "Test" mailbox does not exist, dovecot sieve would first create it and then deliver email into it. Now dovecot imap should notify IDLE client that new message into virtual "All" mailbox was delivered (as it collects emails from all - * - mailboxes). But dovecot for some unknown reason does not notify via IDLE that there is a new email. To get notifications, it is needed to re-open that "All" mailbox again. -- Pali Rohár pali.rohar(a)gmail.com

Hello all, I have version 2.3.3-2 of dovecot and could see version 2.3.4-2 available from the repos. How is feedback after upgrade to 2.3.4-2? Any issues? Can I revert back to older version if I face any problems? Cheers/DP

ssh_dh?
by Daniel Miller 17 Dec '18

17 Dec '18

Don't know if this was corrected in 2.3.4 (haven't upgraded yet but didn't see it in the notes) - but in 2.3.3 I see this in my log: imap-login: Error: Diffie-Hellman key exchange requested, but no DH parameters provided. Set ssh_dh=</path/to/dh.pem So...either there's an undocumented feature of SSH-over-IMAP (that's Dovecot - always on the cutting edge!) or someone had a coffee shortage during a coding session... -- Daniel

Upgrade to 2.3.1 has failed
by C. Andrews Lavarre 17 Dec '18

17 Dec '18

Problem: We had Dovecot v2.2 working just fine under openSUSE Leap 42.3. But we upgraded openSUSE to Leap 15.0. In the process, Dovecot got upgraded from 2.2 to 2.3.1. It no longer works and I haven't figured out how to downgrade to the older working version. The key issue seems to be the change to requiring dh.pem and changing s sl_protocols to ssl_min_protocols. I think I've navigated both correctly, but it still doesn't work. The error is auth: Error: stats: open(old-stats-user) failed: Permission denied as a consequence of which we get imap-login: Error: Failed to initialize SSL server context: Can't load SSL certificate: There is no valid PEM certificate. We have followed the instructions at https://wiki.dovecot.org/S SL/DovecotConfiguration 1. We have created /etc/dovecot/dh.pem (yes it took five hours) 2. We have edited 10-ssl.conf as directed by the Wiki: ssl = yes ssl_cert = /etc/certbot/live/privustech.com/fullchain.pem ssl_key = /etc/certbot/live/privustech.com/privkey.pem ssl_dh = /etc/dovecot/dh.pem #(yes, it took five hours to create...) ssl_min_protocol = TLSv1 ssl_cipher_list = ALL:!kRSA:!SRP:!kDHd:!DSS:!aNULL:!eNULL:!EXPORT:!DES:!3DES:!MD5:!PSK:!RC4:!ADH:!LOW@STRENGTH ssl_prefer_server_ciphers = no 3. We have checked 10-ssl.conf against the 2.3 default at https://github.com/dovecot/core/blob/master/doc/example-config/conf.d/10-ss… 4. We do NOT include the less than (<) symbol before the paths because then dovecot fails to load complaining it cannot find the files. 5. we have checked all the pem keys, certificates, and dh files with cat, they all exist and are in the expected hash format. 6. We have followed the instructions to set their permissions root:root 0444 and 0400 accordingly. 7. We have rebooted the host. Any help or clues would be most appreciated. Kind regards, Andy

mailbox locking
by Victor Sudakov 16 Dec '18

16 Dec '18

Dear Colleagues, I use exim's appendfile transport, procmail and a local mutt on my system, they all (to my knowledge) use lockfiles when working with mboxes. However, `doveconf | grep lock` says dotlock_use_excl = yes lock_method = fcntl mail_max_lock_timeout = 0 mbox_dotlock_change_timeout = 2 mins mbox_lock_timeout = 5 mins mbox_read_locks = fcntl mbox_write_locks = dotlock fcntl pop3_lock_session = no Do I need to change anything in dovecot's default locking setup? Does it still use lockfiles on mboxes or not? There are some contradictory parameters IMHO. -- Victor Sudakov, VAS4-RIPE, VAS47-RIPN 2:5005/49@fidonet http://vas.tomsk.ru/

Feature request SCRAM-SHA-256

Hi, is that here the right place to make feature requests? dovecot supports as authentication mechanism SCRAM-SHA-1 from RFC 5802 which was updated to SCRAM-SHA-256 in RFC 7677 Can SCRAM-SHA-256 be added to the authentication mechanisms? I would not like to request, that SCRAM-SHA-1 will be exchanged by SCRAM-SHA-256, since several applications only support SCRAM-SHA-1 Regards Torsten

Alexander hi. Aki caught the STARTTLS issue as well, I corrected it, but it still doesn't work. Enjoy your weekend. I intend to enjoy mine! :-) Thanks again for your time.

If you and Alexander are stumped then surely I am too! I swear I didn't change anything, and indeed have tried going back to the backup of 10- ssl.conf, which worked under 2.2, but doesn't under 2.3 even after making the changes described in the upgrade documentation. All I did was change all the repositories to Leap 15.0 from Leap 42.3 and execute zypper dup. It took several hours to complete at which point everything works just fine, except that Dovecot was upgraded from 2.2.xxx? to 2.3.1 without my even agreeing to it... :-( This version 2.3.1 is the openSUSE repository offering for their Leap 15.0. I tried finding a rollback version yesterday—2.2.3, 2.2.9... I don't need all the bells and whistles, I just want it to work—but all had one kind of dependency hell or another... :-( What I've done in the meantime is to mount /home/alavarre/Maildir with sshfs, and then point KMail at it, so I can read and write email without dovecot, but it would be nice to fix it IDC... So maybe the right answer is to try the latest, perhaps in Tumbleweed... I'm usually allergic to self-compiling, I alway seem to find one dependency hell or another, but I'll go ahead and try anyhow. I'll let you know. In the meantime all the failed logins have put me in jail by the provider (Cox Cable) accusing me of being a spammer... :-( But for now I'll go have a gin and tonic and hit it again tomorrow... :-) Enjoy your weekend, and thank you again for your thoughts and time.

Downloading e-mail from a master mail server
by R. Diez 14 Dec '18

14 Dec '18

Hi all: I am trying to migrate a small company from Microsoft Exchange / Outlook to Thunderbird. I am evaluating e-mail server software. We have an Internet provider that we do not really want to rely upon. We also do not have the resources to maintain a mail server visible from the outside, especially regarding security updates. Each employee has an e-mail account on our current Internet provider, and one e-mail account on our internal Exchange Server. Our Exchange server periodically downloads all e-mails from the Internet provider mailboxes to its local mailboxes. Therefore, employees cannot access their e-mails when travelling. We have worked this way for years without problems. There are other ways, like VPN access etc, but we do not have the resources to install or maintain more IT stuff. So I would like to keep this setup, with one important difference: e-mails on the Internet provider mailboxes should remain there for a couple of weeks. This is similar to Thunderbird's option "Leave a copy on server" together with "For at most xx days". This way, employees could access at least their most recent e-mails when travelling, if only over the Internet provider's web interface. I could achieve such a setup without a local mail server at all, only with the Thunderbird clients, but I have not figured out yet how to automatically backup all mailboxes. See this question of mine: https://support.mozilla.org/en-US/questions/1243605 So I am trying to design a solution with Dovecot, but I know too little about mail servers. How could I configure Dovecot / MTAs / whatever in order to achieve the "Leave a copy on server" together with "For at most xx days" mentioned above? This way, Dovecot does not need to be exposed on the Internet. Failing that, could someone tell me at least how to configure Dovecot / whatever to download the external IMAP mailboxes to the internal IMAP mailboxes? When I read about Postfix and the like, I see SMTP and e-mail queues, but that's not what I need. This guy wants a similar setup: https://serverfault.com/questions/500591/fetch-all-mail-from-an-imap-server… But I did not understand the Fetchmail part, which seems to be discouraged anyway: "Fetchmail can be used as a POP/IMAP-to-SMTP gateway for an entire DNS domain, collecting mail from a single drop box on an ISP and SMTP-forwarding it based on header addresses. (We don't really recommend this, though, as it may lose important envelope-header information. ETRN or a UUCP connection is better.)" I also haven't understood yet the backup part with Dovecot. There is no central e-mail database like in Microsoft Exchange, right? How do I backup all mailboxes for all users? I probably need to stop the Dovecot server an any MTAs before backing the raw files underneath, right? Many thanks in advance, rdiez

Dovecot IMAP connections
by j.emerlik 11 Dec '18

11 Dec '18

What exactly means "deinit". Yesterday I had all IMAP processes with word "deinit" in brackets and dovecot reached the limit of processes. I had to do a restart of the process. eg.: dovecot 32482 0.0 0.0 24832 4256 ? S 03:29 0:00 dovecot_host1/imap [pierrot xxx.xxx.xx.xx (deinit)] Dovecot version 2.2.32. Regards, Jack

dovecot user id and mail folder permissions, was "no shared cipher"
by Marco Fioretti 11 Dec '18

11 Dec '18

Greetings, I thought it may be better to start a separate thread now that the cipher problem is solved. Background: I have had to recreate from scratch, and without notice, a working server to a new VPS, with different versions of dovecot and other software. Now I am having problems with accessing the imap folders from home. Now I have postfix/procmail successfully delivering email to the right IMAP folders. Problem is, postfix/procmail run as user mail_manager, group mail_management, and the permissions on those folders are currently all set to 755. The consequence is that dovecot, running as user "dovecot", extra group mail_management, cannot modify those folders and their indexes. What is the best/safest configuration in these cases? 1) run dovecot too as user "mail_manager"? (if yes, how, with dovecot 2.2.36?) 2) recursively change permissions of ALL the mail folders and files to 775? 3) both 1) and 2) ? 4) other (e.g. certain permissions for folders, others for specific files? Thanks in advance for any advice! Marco

"no shared cypher", no matter what I try
by Marco Fioretti 11 Dec '18

11 Dec '18

Greetings, I have had to reinstall my email server on another Linux (centos 7.6) VPS, with a newer version of dovecot, other software and a brand new letsencrypt certificate just for email withpostfix and dovecot (that certificate works fine with postfix). Output of dovecot --version and dovecot -n on the new server is below. Now, messages ARE delivered in the right IMAP mailboxes, but when I try to connect with Mutt from my home computer, mutt says, before prompting for a password: gnutls_handshake: A TLS fatal alert has been received.(Handshake failed) the corresponding output of dovecot in /var/log/maillog is below. The gist of it **seems** to me to be the "no shared cipher" part, but I may be wrong. In any case, I have already tried to search online for that string, and other relevant parts of the log, without success. All I have found is suggestions to change the values of ssl_protocols and/or ssl_cipher_list to some non-default value, but I have tried all those tips without success. Current values of those variables are these: grep -v ^# /etc/dovecot/conf.d/10-ssl.conf ssl_cert = </etc/letsencrypt/live/MYSERVERNAME/fullchain.pem ssl_key = </etc/letsencrypt/live/MYSERVERNAME/privkey.pem ssl_protocols = !SSLv2 !SSLv3 ssl_cipher_list = ALL:!ADH:!LOW:!EXP:!aNULL:+HIGH:+MEDIU any pointer to what to check or change next is VERY welcome.

Indexer worker small bug
by André Rodier 11 Dec '18

11 Dec '18

Hello, I think I submitted this before, but I am not sure this has been addressed I am using AppArmor with Dovecot, without any issue. However, I think there is a bug in the indexer working, from what I can see, a missing trailing slash. See: ------------ Dec 09 14:35:53 portal2 kernel: audit: type=1400 audit(1544366153.379:3035): apparmor="DENIED" operation="file_mmap" info="Failed name lookup - disconnected path" error=-13 profile="/usr/lib/dovecot/indexer-worker" name="var/cache/nscd/hosts" pid=10540 comm="indexer-worker" requested_mask="r" denied_mask="r" fsuid=1001 ouid=0 ------------ The indexer worker is trying to open the file "var/cache/nscd/hosts" instead of "/var/cache/nscd/hosts", which of course fails. Can someone double check the code of the indexer worker, or this has been fixed? Thanks, André -- https://github.com/progmaticltd/homebox

set seen flag and junk moving a mail manually to JUNK
by Jakobus Schürz 10 Dec '18

10 Dec '18

Hi there! I want to set the \seen and the Junk Flag to an email, which i move manually to my Junk-Folder. I tried a lot... but nothing worked like expected. I have a sieve-filter, which takes an email and copy it to a pipe to rspamc. This filter is working correctly, i get a debug-message from the script, which is called through the sieve-filter. But adding another rule (addflag "Junk"; setflag "\\seen";) to this rule is getting ignored... Here is my sieve-rule: require ["imap4flags", "vnd.dovecot.pipe", "copy", "imapsieve", "environment", "variables"]; if environment :matches "imap.email" "*" { set "email" "${1}"; } addflag "Junk"; setflag "\\seen"; pipe :copy "learn-spam.sh" [ "${email}" ]; How said before, the script learn-spam.sh is called, when i move a Message via drag&drop in thunderbird from the INBOX to the Junk-Folder. But the message in the Junk-Folder is unseen, recent and has no Junk-Flag... What's wrong? BR Jakob

doveadm move and create folders for the archive
by Michael Wagner 08 Dec '18

08 Dec '18

Hello guys, I'm on a few mailinglists, which I want to archive at the end of the year. I know the command to do this, but must I create the folders for the archive by myself or is there a switch for doveadm? I tested this, but it exits with an error about the missing mailbox. doveadm -D copy -u michael Archiv/debian-user/2018 mailbox debian-user since 365d error message: doveadm(michael): Debug: Effective uid=1000, gid=1000, home=/home/michael doveadm(michael): Debug: Namespace inbox: type=private, prefix=, sep=, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:~/Maildir:LAYOUT=fs doveadm(michael): Debug: fs: root=/home/michael/Maildir, index=, indexpvt=, control=, inbox=/home/michael/Maildir, alt= doveadm(michael): Error: Can't open mailbox 'Archiv/debian-user/2018': Mailbox doesn't exist: Archiv/debian-user/2018 Sorry for the long lines.

Segfault when using doveadm batch -A : kick
by Apollon Oikonomopoulos 08 Dec '18

Hi, Apparently the "kick" doveadm_cmd_ver2 struct lacks a .mail_cmd member pointing to an appropriate allocation function, causing a NULL pointer dereference when used via `doveadm batch`.

Different listeners with different config
by Peter Mogensen 07 Dec '18

07 Dec '18

Hi, I was wondering about the status on being able to create a dedicated listener in Dovecot with - say - extra features enabled. As an example... If I wanted to have Dovecot listening on port 144 with a slightly different set of auth mechanisms enabled. /Peter

argonid and dovecote
by Jerry 06 Dec '18

06 Dec '18

on a FreeBSD 11.2 amd64 machine, I am trying to get Dovecot 2.3.4 to play nice with "argonid" encryption. In the "10-auth.conf" file, I tried: auth_mechanisms = plain argon2id Upon restarting dovecot, I received an error message when attempting to actually it: auth: FATAL: Unknown authentication mechanism "ARGON2ID" Output from doveadm pw -l doveadm pw -l SHA1 SSHA512 BLF-CRYPT PLAIN HMAC-MD5 OTP SHA512 SHA RPA DES-CRYPT CRYPT SSHA MD5-CRYPT SKEY PLAIN-MD4 PLAIN-MD5 SCRAM-SHA-1 LANMAN SHA512-CRYPT CLEAR CLEARTEXT ARGON2I ARGON2ID SSHA256 NTLM MD5 PBKDF2 SHA256 CRAM-MD5 PLAIN-TRUNC SHA256-CRYPT SMD5 DIGEST-MD5 LDAP-MD5 I assume I am making a stupid mistake, but I do not know what it is. -- Jerry

Dovecot 2.3.4 crashing on Solaris 10 - "Panic: output stream is missing error handling"
by Fabian Fritz 06 Dec '18

06 Dec '18

Hi, I just compiled Dovecot for Solaris 10 and try to run it now. Other than setting a custom port, I did not add custom settings. When I tried running doveconf for the first time, it crashed immediately: doveconf -n # 2.3.4 (): /export/dovecot/etc/dovecot/dovecot.conf # OS: SunOS 5.10 sun4u~~ # Hostname: merlin service pop3-login { inet_listener pop3 { port = 1110 } } submission_max_mail_size = 0 doveconf: Panic: output stream is missing error handling doveconf: Error: Raw backtrace: 0xff01b3a8 -> 0xff063b04 -> 0x1673c -> 0x1797c -> 0x14478 Abort (core dumped) The same error appears when I run dovecot -F. Unfortunately I currently don't have access to the core dumps (I might do later), but I could run it with the Debugger with user process debugging enabled: (This is the part when it crashes.

Restricting sending mail to domain or group
by admin 06 Dec '18

06 Dec '18

Hi folks, has anybody a simple solution for the following request? I have a group alias (all(a)company.com) (1) Only company.com accounts should be able to send an email to everybody in that company via all(a)company.com. (2) - rather optional: refine the restrictions, e.g. two groups, grp1(a)company.com and grp2(a)company.com. Grp1 members should be able to send mails to grp2 but not vice versa. What else than sieve would keep dealing with that demands as simple as possible? Thanks in advance and sorry for abusing this list for this kind of „problem“ which is not a bug. Regards, -M

Error: Corrupted record in index cache file
by Orion Poplawski 05 Dec '18

05 Dec '18

With dovecot-2.2.36-3.el7.x86_64 we had a couple hours where mail_plugins did not properly include zlib for all of the needed services. This seems to have led to some corruption in our mdbox mailboxes. I've run doveadm force-resync on a number of users, but I'm still seeing messages like this: dovecot[13563]: imap(USER): Error: Corrupted record in index cache file /var/spool/imap/USER/mailboxes/INBOX/dbox-Mails/dovecot.index.cache: UID 67976: Broken physical size in mailbox INBOX: read(zlib(/var/spool/mail/USER/storage/m.1203)) failed: Cached message size smaller than expected (2978 < 8192, box=INBOX, UID=67976) Is there anything that can be done about this? Can I safely delete the dovecot.index.cache file? I'm hesitant to do so since I understand that the mdbox format uses the index to store mailbox information and deleting at least some index files is a destructive operation.

vacation script issue
by fins 05 Dec '18

05 Dec '18

Hello, I have a complete Postfix + Dovecot + openLDAP setup almost working, the only issue I have is the vacation script auto-reply that doesn't work properly. If I send an email to a user with the vacation filter enabled, the auto-reply is send to a local recipient with the same account name. So for example if I send a mail from test(a)xyz.com to test(a)example.com, the auto-reply is received on the test(a)example.com address instead of the test(a)xyz.com who's the original sender. Here's a log file: Dec 3 13:52:48 imap dovecot: lda(test(a)example.com): Debug: sieve: executing script from /var/mail/example.com/test/.dovecot.svbin Dec 3 13:52:48 imap dovecot: lda(test(a)example.com): sieve: msgid=< dovecot-sieve-1543841568-836314-0(a)imap.example.com>: discarding vacation response to auto-submitted message from <MAILER-DAEMON> Dec 3 13:52:48 imap dovecot: lda(test(a)example.com): sieve: msgid=< dovecot-sieve-1543841568-836314-0(a)imap.example.com>: stored mail into mailbox 'INBOX' Dec 3 13:52:48 imap postfix/pipe[6663]: D835A300E05: to=<test(a)example.com>, orig_to=<test(a)xyz.com>, relay=dovecot, delay=0.1, delays=0.03/0.01/0/0.06, dsn=2.0.0, status=sent (delivered via dovecot service) Can somebody help with this issue and/or point where to go for debugging?

Random issue on mailbox "assertion failed"

Hi, Since few weeks, I have regularly the issue below with some mailboxes - This is happening randomly. Users are complaining emails are not visible.

And what about the "dovecot-keywords" files in both folders? Do they match? The letter "a" seems to indicates that there is at least one non-standard flag defined in the source folder's keywords. By the way, can I assume you move messages only by using Thunderbird/IMAP and not by manipulating the file system? Here's how things look on my server: # On arrival (UNSEEN) 1543968031.M941319P5841.foo,S=1390,W=1422:2, # After reading (SEEN) 1543968031.M941319P5841.foo,S=1390,W=1422:2,S # After being moved to another folder (SEEN) 1543968031.M941319P5841.foo,S=1390,W=1422:2,S I can use IMAP search terms SEEN and UNSEEN as indicated above, and I see the same message state displayed in Notmuch mail (my default, it accesses Dovecot's Maildir storage directly) and various IMAP clients connecting to Dovecot.

dovecot and argon2 encryption
by Jerry 04 Dec '18

04 Dec '18

I am using a FreeBSD 11-2 amd/64 system with dovecot version 2.3.4 installed. I was playing around with different encryption schemes. doveadm pw -l SHA1 SSHA512 BLF-CRYPT PLAIN HMAC-MD5 OTP SHA512 SHA RPA DES-CRYPT CRYPT SSHA MD5-CRYPT SKEY PLAIN-MD4 PLAIN-MD5 SCRAM-SHA-1 LANMAN SHA512-CRYPT CLEAR CLEARTEXT SSHA256 NTLM MD5 PBKDF2 SHA256 CRAM-MD5 PLAIN-TRUNC SHA256-CRYPT SMD5 DIGEST-MD5 LDAP-MD5 There is no mention of "argon2" shown. Now, from the command line I can enter this command: ~ $ echo -n "Secret-Password" | argon2 somesalt Type: Argon2i Iterations: 3 Memory: 4096 KiB Parallelism: 1 Hash: e6432f595e999988c7c54c30d530b0fc7d9953510e5ccf295359258f4ea22a3d Encoded: $argon2i$v=19$m=4096,t=3,p=1$c29tZXNhbHQ$5kMvWV6ZmYjHxUww1TCw/H2ZU1EOXM8pU1klj06iKj0 0.039 seconds Verification ok However, this fails: doveadm pw -p "Secret-Password" -s argon2 Fatal: Unknown scheme: ARGON2 I have tried different ways to enter "argon2", but nothing works. Can someone tell me what I am doing wrong? Thanks :) -- Jerry

Hi there! I've installed dovecot for debian from the dovecot-repo in the latest Version 2:2.3.4-2~stretch And i still get this error-messages. dovecot[5817]: imap(user.name)<26484><nzUgti58YaEuffpZ>: Error: Log synchronization error at seq=4,offset=5748 for /var/lib/dovecot/db/indexes/Maildir/user.name/Trash/dovecot.index: Append with UID 202, but next_uid = 203 I read in the release-notes, that doveadm force-resync can solve this problem... But it didn't I ran the command on all Mailboxes, but deleting a message in Thunderbird (= moving it into Trash) causes the error above. Do you need further informations? BG jakob

Mailing list address harvested for spamming
by dovecot-e51＠deemzed.uk 03 Dec '18

03 Dec '18

Not to stir the pot, but I notice my email address has recently been harvested from this list for spamming purposes. This email address is unique and not used for anything else. I'd distinguish this from spam sent to the mailing list itself, which is obviously different. Is there anything further that could be done to prevent this? -- Dave

Relocate subfolders to different mount point
by Marc Roos 03 Dec '18

03 Dec '18

I would like to relocate the subfolders of the Sent folder to a different location. Now send messages mail is stored in mbox format at the location /home/users/testuser/mail/.Sent. I would like to store the subfolders Sent/2017 and Sent/2018 at the location /home/archive/users/testuser/.Sent.2017 and /home/archive/users/testuser/.Sent.2018 Is this even possible? I am using currently using this mail_location: mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u:CONTROL=~/mail/control:INDEX=/var/d ovecot/%u/index:LAYOUT=maildir++ /var/dovecot is on a ssd /var/spool/mail is on sda ~/mail is on sdb with these folders [@mail]# ls -ac1 .folderc .Drafts .foldera control .Trash.folderc .folderb .Sent .Sent.2018 .Trash

The tool metaphor is realistic. In my experience (which dates back to the 1980s), email ist a powerful tool, and people need to learn how to use it properly, with the appropriate software set.

Sieve broken after upgrade
by Pavel Stratil 02 Dec '18

02 Dec '18

Hi everyone, after switching to ubuntu (from debian) and running a newer dovecot --version 2.2.33.2 (d6601f4ec) i encountered a problem with configuring sieve. The mailserver has virtual maila accounts stored in /decrypted/%d/%n Prior, i used plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_before = /etc/dovecot/sieve/before.d } after the upgrade, I moved the sieve_before location on disk and changed this to plugin { sieve = file:~/sieve;active=~/.dovecot.sieve sieve_before = /var/lib/dovecot/sieve/before.d } only to see that sieve didnt forward e-mails anymore. Looking at the logs below, i suspect, that I didnt understood the meaning of sieve = file:~/sieve;active=~/.dovecot.sieve correctly: Dec 2 16:01:57 vao01 dovecot: lmtp(events(a)industra.space): Debug: Module loaded: /usr/lib/dovecot/modules/lib90_sieve_plugin.so Dec 2 16:01:57 vao01 dovecot: lmtp(events(a)industra.space): Debug: sieve: Pigeonhole version 0.4.21 (92477967) initializing Dec 2 16:01:57 vao01 dovecot: lmtp(events(a)industra.space): Debug: sieve: include: sieve_global is not set; it is currently not possible to include `:global' scripts.

I tried several combinations of configuring this, but I seem to miss some important point. Would you kindly help me get this right? Configs are attached. Thanks in advance, Pavel

Dovecot crash
by JCA 01 Dec '18

01 Dec '18

This happening when my Thunderbird client is trying to establish a connection with a Dovecot server. Some background first: 1) I am running Thunderbird 6.20.1 from a Linux client. 2) Other clients (e.g. Maildroid in my Android phone) do not have any issues. 3) The Dovecot software is version 2.2.9, running in a Linux server. 4) This may be the root of the problem: at some point, the Dovecot software was changed to version 2.3.1, and the reverted to 2.2.9. The crash started to appear when this reversion took place. My guess is that upgrading to 2.3.1 will eliminate this problem. However, in case that does not solve the problem, I would be grateful if anybody could throw some light into exactly what is going on here, and whether it can be fixed even without the need of upgrading to 2.3.1. What follows are the traces generated by Dovecot 2.2.9 when a connection is attempted from Thunderbird, with usernames and IP addresses disguised for privacy, and some blank lines inserted for readability: Nov 28 13:36:20 imap-login: Info: Login: user=<xyz>, method=PLAIN, rip=xxx.yyy.z zz.154, lip=aaa.bbb.ccc.7, mpid=29245, TLS, session=<q7jNhL97qQDMhbWa> Nov 28 13:36:20 imap(xyz): Panic: file mail-index-sync-keywords.c: line 227 (key words_update_records): assertion failed: (data_offset >= sizeof(struct mail_index_record)) Nov 28 13:36:20 imap(xyz): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so. 0(+0x65626) [0xb75ae626] -> /usr/lib/dovecot/libdovecot.so.0(+0x6569f) [0xb75ae6 9f] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0xb756180e] -> /usr/lib/dove cot/libdovecot-storage.so.0(mail_index_sync_keywords+0x707) [0xb76cb6b7] -> /usr /lib/dovecot/libdovecot-storage.so.0(mail_index_sync_record+0xf7) [0xb76cc167] - > /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_sync_map+0x2a4) [0xb76cd22 4] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_map+0x57c) [0xb76bcb9c ] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0xb7c2a) [0xb76b7c2a] -> /usr/lib /dovecot/libdovecot-storage.so.0(+0xb7daa) [0xb76b7daa] -> /usr/lib/dovecot/libd ovecot-storage.so.0(mail_index_open+0x114) [0xb76b7f54] -> /usr/lib/dovecot/libd ovecot-storage.so.0(index_storage_mailbox_open+0xab) [0xb76a808b] -> /usr/lib/do vecot/libdovecot-storage.so.0(+0x5a481) [0xb765a481] -> /usr/lib/dovecot/libdove cot-storage.so.0(+0x5a6f2) [0xb765a6f2] -> /usr/lib/dovecot/libdovecot-storage.s o.0(+0x7a017) [0xb767a017] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_o pen+0x26) [0xb767a1d6] -> dovecot/imap(client_open_save_dest_box+0x79) [0x805dca 9] -> dovecot/imap() [0x8052678] -> dovecot/imap(command_exec+0x32) [0x805d7a2] -> dovecot/imap() [0x805c746] -> dovecot/imap() [0x805c820] -> dovecot/imap(clie nt_handle_input+0x125) [0x805cad5] -> dovecot/imap(client_input+0x71) [0x805ce91 ] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x42) [0xb75c1292] -> /usr /lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xdb) [0xb75c22cb] -> /usr/lib/ dovecot/libdovecot.so.0(io_loop_run+0x48) [0xb75c0cd8] -> /usr/lib/dovecot/libdo vecot.so.0(master_service_run+0x2d) [0xb756728d] -> dovecot/imap(main+0x2bf) [0x 8066fef] -> /lib/libc.so.6(__libc_start_main+0xe6) [0xb73cfdb6] Nov 28 13:36:20 imap(xyz): Fatal: master: service(imap): child 29245 killed with signal 6 (core dumps disabled) Nov 28 13:36:20 imap-login: Info: Login: user=<xyz>, method=PLAIN, rip=xxx.yyy.z zz.154, lip=aaa.bbb.ccc.7, mpid=29247, TLS, session=<xPzShL97lADMhbWa> Nov 28 13:36:21 imap(xyz): Panic: file mail-index-sync-keywords.c: line 227 (key words_update_records): assertion failed: (data_offset >= sizeof(struct mail_inde x_record)) Nov 28 13:36:21 imap(xyz): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so. 0(+0x65626) [0xb7757626] -> /usr/lib/dovecot/libdovecot.so.0(+0x6569f) [0xb77576 9f] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0xb770a80e] -> /usr/lib/dove cot/libdovecot-storage.so.0(mail_index_sync_keywords+0x707) [0xb78746b7] -> /usr /lib/dovecot/libdovecot-storage.so.0(mail_index_sync_record+0xf7) [0xb7875167] - > /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_sync_map+0x2a4) [0xb787622 4] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_map+0x57c) [0xb7865b9c ] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0xb7c2a) [0xb7860c2a] -> /usr/lib /dovecot/libdovecot-storage.so.0(+0xb7daa) [0xb7860daa] -> /usr/lib/dovecot/libd ovecot-storage.so.0(mail_index_open+0x114) [0xb7860f54] -> /usr/lib/dovecot/libd ovecot-storage.so.0(index_storage_mailbox_open+0xab) [0xb785108b] -> /usr/lib/do vecot/libdovecot-storage.so.0(+0x5a481) [0xb7803481] -> /usr/lib/dovecot/libdove cot-storage.so.0(+0x5a6f2) [0xb78036f2] -> /usr/lib/dovecot/libdovecot-storage.s o.0(+0x7a017) [0xb7823017] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_o pen+0x26) [0xb78231d6] -> dovecot/imap(client_open_save_dest_box+0x79) [0x805dca 9] -> dovecot/imap() [0x8052678] -> dovecot/imap(command_exec+0x32) [0x805d7a2] -> dovecot/imap() [0x805c746] -> dovecot/imap() [0x805c820] -> dovecot/imap(clie nt_handle_input+0x125) [0x805cad5] -> dovecot/imap(client_input+0x71) [0x805ce91 ] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x42) [0xb776a292] -> /usr /lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xdb) [0xb776b2cb] -> /usr/lib/ dovecot/libdovecot.so.0(io_loop_run+0x48) [0xb7769cd8] -> /usr/lib/dovecot/libdo vecot.so.0(master_service_run+0x2d) [0xb771028d] -> dovecot/imap(main+0x2bf) [0x 8066fef] -> /lib/libc.so.6(__libc_start_main+0xe6) [0xb7578db6] Nov 28 13:36:21 imap(xyz): Fatal: master: service(imap): child 29247 killed with signal 6 (core dumps disabled)

Replacing email envelope
by jon.sp2＠wp.pl 30 Nov '18

30 Nov '18

Hi, Could you please advice how I can replace envelope of a message received on my server? Best would be using sieve. Simple case - email A(a)example.com receives message, which I'd like to repack into new envelope (I want to have control what values in the envelope will be there - from, to, replay-to et.c) and send to B(a)test.com . At first I wanted to use editheader extension, but it is not allowing me to modify From or To values as far as I can tell. Another idea was to use envelope, but I don't see any way of editing values. Only reading. Now, I am thinking of writing script and from sieve it will be passed there, where I'll do message parsing and send new message using mutt or something similar. Frankly speaking I suppose there is much better solution to that and I'd appreciate any advice on the topic. Thanks, Jon

rspamd / imapsieve script is not executed/called
by Michael Ludwig 30 Nov '18

30 Nov '18

Hi to all of you, as I am struggling around with this a week or so I'm afraid I have to ask for help here. The problem is sitting right in front of the computer, as most of the time. ;-) So let me explain: Dovecot is working properly for IMAP with LE certificates, so I thought it's time to continue with Christoph Haas tutorial primarily and other blogs and tutorials for setting up the server. Next part would be to get rspamd learning what mails the user puts into junk folder. I followed the tutorial, but it will not work. Also I tried to get into debug mode, but I feel that dovecot is not really logging too much.

Best way of merging mbox files
by Marc Roos 30 Nov '18

30 Nov '18

When concatenating mbox files like described here https://xaizek.github.io/2013-03-30/merge-mbox-mailboxes/. You will end up with an 'unsorted' mbox file. Is this going to be a problem esspecially when they are large >2GB's and new emails will be written to it? The email client nicely sorts the message from folder A "foldera 5 last" as last, but of course the mbox is not like this. Is there a better solution for merging files? Having: A folder A with messages: From Subject Received Size test foldera 1 16:18 665 B test foldera 2 16:18 665 B test foldera 3 16:18 665 B test foldera 4 16:18 665 B test foldera 5 last 16:29 670 B A folder B with messages: From Subject Received Size test folderb 1 16:23 665 B test folderb 2 16:24 665 B test folderb 3 16:24 665 B test folderb 4 16:24 665 B test folderb 5 16:24 665 B [@ mail] cat .foldera .folderb > .folderc Getting a folder C with messages: From Subject Received Size test foldera 1 16:18 665 B test foldera 2 16:18 665 B test foldera 3 16:18 665 B test foldera 4 16:18 665 B Mail System Internal Data DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA 16:19 454 B test folderb 1 16:23 665 B test folderb 2 16:24 665 B test folderb 3 16:24 665 B test folderb 4 16:24 665 B test folderb 5 16:24 665 B test foldera 5 last 16:29 670 B

"merging" folders Sent-Items Sent-Messages Sent
by Marc Roos 29 Nov '18

29 Nov '18

I have a running server and would like to clean up a bit, and merge sent folders and trash folders etc. Is this best done via the mailbox alias plugin like mentioned here? Or is there a better way? I prefer to have one folder listed at the client, and not "Unfortunately it also means that some clients will download the same mails to local cache multiple times." https://wiki2.dovecot.org/Plugins/MailboxAlias dovecot-2.2.10-8.el7.x86_64 CentOS Linux release 7.5.1804 (Core)

Solr: URI Too Long
by azurit＠pobox.sk 29 Nov '18

29 Nov '18

Hi, i'm quite often getting this error: Error: fts_solr: Lookup failed: 414 URI Too Long Most web servers are limiting URI length to 8192 characters. Why not to use POST instead of GET when communicating with Solr? Solr is able to handle this ok, also see: https://dzone.com/articles/solr-select-query-get-vs-post azur

determine why mail clients download mails 2nd time
by Poliman - Serwis 29 Nov '18

29 Nov '18

I have strange problem. In last Friday I had a problem with dovecot. It didn't see directories with mailboxes in /var/vmail. Somehow it crashed because probably two things (a lot of this type of lines in mail.err file): *Nov 23 07:05:02 s1 dovecot: lda(poli(a)poli.li <poli(a)poli.li>): Error: User initialization failed: Initializing mail storage from mail_location setting failed: mkdir(/var/vmail/poli.li/poli/Maildir <http://poli.li/poli/Maildir>) failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing +w perm: /var/vmail, dir owned by 0:0 mode=0755)* and maybe *Nov 12 09:27:59 s1 dovecot: imap(artur(a)firmastanaszek.pl <artur(a)firmastanaszek.pl>): Error: Corrupted index cache file /var/vmail/firmastanaszek.pl/artur/Maildir/dovecot.index.cache <http://firmastanaszek.pl/artur/Maildir/dovecot.index.cache>: Broken MIME parts for mail UID 559 in mailbox INBOX: Cached MIME parts don't match message during parsing: Cached header size mismatch (parts=)Nov 12 09:27:59 s1 dovecot: imap(artur(a)firmastanaszek.pl <artur(a)firmastanaszek.pl>): Error: unlink(/var/vmail/firmastanaszek.pl/artur/Maildir/dovecot.index.cache <http://firmastanaszek.pl/artur/Maildir/dovecot.index.cache>) failed: No such file or directory (in mail-cache.c:28)* and after this event probably all mailboxes download again all emails from 1.11 to 22.11. They were duplicated in mail clients. -- *Pozdrawiam / Best Regards* *Piotr Bracha*
