Unable to authenticate on Dovecot - auth-userdb issue?

Some general information: Mageia Linux 5.4.6-desktop-2.mga7 2.3.7.2 (3c910f64b) postfix + dovecot + mysql 192.168.1.105 (shuttle) the email server machine 192.168.1.103 (pvr) the mail client machine I am unable to authenticate to send email. I've looked at postfix but I can't get past dovecot's authentication. Here is what I'm seeing in logs: Jan 02 18:46:47 shuttle sshd[6660]: Connection closed by 192.168.1.100 port 48506 [preauth] Jan 02 18:47:05 shuttle postfix/smtpd[6352]: connect from pvr[192.168.1.103] Jan 02 18:47:16 shuttle postfix/smtpd[6352]: lost connection after CONNECT from pvr[192.168.1.103] Jan 02 18:47:16 shuttle postfix/smtpd[6352]: disconnect from pvr[192.168.1.103] commands=0/0 Jan 02 18:47:36 shuttle postfix/smtpd[6352]: connect from pvr[192.168.1.103] Jan 02 18:47:36 shuttle postfix/smtpd[6352]: 6345D4A4A97: client=pvr[192.168.1.103] Jan 02 18:47:37 shuttle postfix/cleanup[6500]: 6345D4A4A97: message-id=<> Jan 02 18:47:37 shuttle postfix/qmgr[1385]: 6345D4A4A97: from=<madams@pvr>, size=485, nrcpt=1 (queue active) Jan 02 18:47:37 shuttle postfix/smtpd[6352]: disconnect from pvr[192.168.1.103] helo=1 mail=1 rcpt=1 data=1 quit=1 commands=5 Jan 02 18:47:37 shuttle dovecot[6744]: lda(root@shuttle)<6744><>: Error: auth-master: userdb lookup(root@shuttle): connect(/run/dovecot/auth-userdb) failed: Permission denied (euid=8(mail) egid=12(mail) missing +r perm: /run/dovecot/auth-userdb, dir owned by 0:0 mode=0755) Jan 02 18:47:37 shuttle dovecot[6744]: lda: Fatal: Internal error occurred.

iOS Client Not Showing Email Previews, Dovecot Issue?
by asai＠globalchangemusic.org 02 Jan '20

02 Jan '20

Greetings, Just wondering if anybody would know why one of our users' iOS Mail app client doesn't show the email previews (the first few sentences of the email)? We had migrated from an earlier (2.2.4) version of Dovecot to the latest version and once that was done, the user began to report this issue. I don't know if it's a Dovecot issue or not, but can anyone point me in the right direction to begin to debug? Thank you, Asai

spamsieve question
by Gerben Wierda 31 Dec '19

31 Dec '19

My new dovecot covers spam/ham training through the standard Spam_train and Notspam_train mailboxes. When a message is copied (I’m using macOS/iOS standard Apple clients) it triggers the spam/ham learning by rspamd. So far so good. When I move a message to Spam_train I’d like it to be removed immediately after learning. When I move a message to Notspam_train, I’d like it to move back where it came from after having been piped The first is I think doable, but how? Is the second doable?

Problem with big number of pop3-login [1 pre-login]
by Григорий Семенов 30 Dec '19

30 Dec '19

Dear all, I have recently migrated from my old Debian 8 (jessie) system to a new VM with fresh Debian 10 (buster) installation. Previous dovecot version was 2.2.13 and now I have 2.3.4.1. Dovecot was setup from Debian packages. Mostly, it is working, but one problem is just frustrating me. The number of some pop3-login processes are getting higher and higher until they reach my login_max_processes_count option which is equal 1000. From ps aux it looks like this: dovecot 55067 0.0 0.0 8192 6340 ? S 00:09 0:00 dovecot/pop3-login [1 pre-login] dovecot 55344 0.0 0.0 8192 6388 ? S 00:35 0:00 dovecot/pop3-login [1 pre-login] dovecot 55351 0.0 0.0 8192 6268 ? S 00:35 0:00 dovecot/pop3-login [1 pre-login] dovecot 55354 0.0 0.0 8192 6388 ? S 00:35 0:00 dovecot/pop3-login [1 pre-login] dovecot 55594 0.0 0.0 8192 6280 ? S 00:36 0:00 dovecot/pop3-login [1 pre-login] dovecot 56822 0.0 0.0 8192 6300 ? S 00:36 0:00 dovecot/pop3-login [1 pre-login] dovecot 56996 0.0 0.0 8192 6268 ? S 00:36 0:00 dovecot/pop3-login [1 pre-login] … Once it reaches the login_max_processes_count value my users start to complain to no new mail is arriving. Restart resolves the problem just for some time, until it will come to a limit next time (sometimes it take 1 day, sometimes 1 hour). In my old system I had nothing like that, but I guess it could be done something wrong during migration. I don’t know if it is significant but instead of real users I deal with only one third-party application which utilizeses 5 simultaneous tcp connections to check mailboxes via SSL\TLS. My dovecot is not public, and there is nothing else besides these 5 connections. Currently, in a config I have this: service pop3-login { process_min_avail = 4 process_limit = 4 client_limit = 100 service_count = 100 Please friends give me a way how to handle the situation. Might it be a bug? ========= Regards, Greg Semenov

Re: Issue running Dovecot in Docker Container

I'm not using internal logging. I'm running the docker with the logging to the host. I have used the same options you have specified. The problem is that the below processes are not running inside docker container whereas the standalone dovecot is running these processes(meaning without container) dovecot-Dovecot/auth dovecot-Dovecot/ssl-params dovecot-Director/lmtp dovecot-Director/ssl-params dovecot-Director/imap-login director Thanks & Regards, Naveen On Mon, Dec 30, 2019 at 3:16 PM Marc Roos <M.Roos(a)f1-outsourcing.eu> wrote: > > If you are running your container as root.

Using "doveadm pw" as unpriviledged user
by Ralf Jung 29 Dec '19

29 Dec '19

Hi all, Some time ago, I wrote a small CGI script to let users change their IMAP password. The script runs as www-data user and uses "doveadm pw" to check if a password hash matches a password. Unfortunately, this means that I have to make large parts of my dovecot config world-readable, as otherwise I get errors like this: doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/10-auth.conf line 123: Couldn't open include file /etc/dovecot/conf.d/auth-sql.conf.ext: Permission denied I understand doveadm also does plenty of things that interact with the running dovecot instance and thus need access to the config, but for generating hashes or comparing hashes with passwords, it should not be necessary to read the dovecot config. This shouldn't require a properly setup dovecot on this machine at all, in fact. I'd prefer to make the config not world-readable, and indeed the Debian packaging sometimes makes those files not-world-readable on upgrades, breaking my setup. Is there any way to call "doveadm pw" as a users that cannot read the dovecot config on the current machine? This happens with the following versions of the dovecot debian package: 1:2.3.4.1-5+deb10u1~bpo9+1, 1:2.3.4.1-5+deb10u1 Thanks! Ralf PS: Please keep me in Cc, as I am not subscribed to the list.

Packages missing from repo
by Jon Geerars 29 Dec '19

29 Dec '19

Hi, Since a couple of weeks the Dovecot packages for Debian Jessie and Ubuntu Trusty have disappeared from the repo. According to https://repo.dovecot.org/ they should be in https://repo.dovecot.org/ce-2.3-latest/debian/jessie and https://repo.dovecot.org/ce-2.3-latest/ubuntu/trusty, but that leads to a 404. Where can I find them? Jon

Dovecot proxy: authentication best practices
by William Edwards 28 Dec '19

28 Dec '19

Hi! I have a few questions regarding Dovecot proxy: 1. 1.1 If I understand correctly, setting 'nopassword' in the proxy passdb file, authentication is completely up to the destination host. Setting 'nopassword' in no way means the proxy becomes an open relay. Is this correct? 1.2 Are there any security implications when using 'nopassword' on the proxy? 2. 2.1 I would like to avoid having to store all users in a passdb file on the proxy. I would much rather specify a domain for which Dovecot proxy will route all users to a specific host. Is there a way to let Dovecot proxy route to a destination host based on domain, so individual users don't have to be specified in the proxy passdb? 2.2 Is it correct that userdb does not have any effect on proxying and it can be left out of the config? Source: https://dovecot.org/pipermail/dovecot/2013-October/093138.html (point 2) Met vriendelijke groeten, William Edwards T. 040 - 711 44 96 E. wedwards(a)cyberfusion.nl

Setting up expunge rules on a per user basis?
by Peter Reinhold 27 Dec '19

27 Dec '19

Hi all, I was wondering, is it possible to setup for instance expunge rules on a per user basis, when I am using userdb SQL lookups (or, possibly via post-login scripts) Reading the docs it seems like its possible, but I am not entirely sure about the data I should return, so have any of you done something like this, and could maybe post an example? -- Peter Reinhold

by ＠lbutlr 26 Dec '19

26 Dec '19

I have an account that mostly receives automated emails with attachments. I would like to save those attachments outside of the mail/IMAP area and then add a link (in the headers) to the saved attachment in the original mail. I do not need to strip the attachment from the email. I’ve looked at 10-mail.conf. but I am using Maildir and I do not want to alter the email other than adding a header like X-Local-link: URL://server/path/to/file If mdbox or sdbox are the only options for this, can I specify that for a single user account instead of for all my users? My other idea was to break out my old ripmime script that I wrote for procmail and do something in sieve like if anyof (header :contains [“content-type"] [ “multiupart”, “other types”]) { fileinto :create “TempAttach”; } And then let ripmime loose on .TempAttach/new/ via a periodic cron job knowing the message would end up being filed in whatever default mailbox after the copy was dropped in the temp mail, but that doesn’t get me the added header with the link to the attachment without a lot of work. I suppose I could generate a second mail with the details of the attachment (size, name, sender, date). Not ideal. Suggestions? -- No one ever thinks of themselves as one of Them.

Thunderbird, server side filtering (sieve) and new email not in "inbox"
by Jesus Cea 25 Dec '19

25 Dec '19

Migrating my extensive thunderbird filtering rules to sieve has the unfortunate effect that thunderbird doesn't realize that there is new email in other mailboxes beside "inbox". According to ancient documentation, <http://kb.mozillazine.org/How_do_I_check_for_new_messages_in_other_folders#…>, I could configure Thunderbird to check each mailbox periodically, but I have >500 mailboxes and I rather prefer the server to notify the client when new email is avaliable somewhere. Reading between lines in that document, looks like Thunderbird would support STATUS updates while in "IDLE". Is that the case?. Do you know how could I configure dovecot to provide that kind of information to thunderbird?. Maybe some extension? I am aware of "notify", but thunderbird is not "notify" compatible. I can write an IMAP4 proxy to "inject" replies to thunderbird side-fetched via "notify", but I need to know what thunderbird expect. Do you have any idea?. Thanks for your time and expertise. -- Jesús Cea Avión _/_/ _/_/_/ _/_/_/ jcea(a)jcea.es - http://www.jcea.es/ _/_/ _/_/ _/_/ _/_/ _/_/ Twitter: @jcea _/_/ _/_/ _/_/_/_/_/ jabber / xmpp:jcea@jabber.org _/_/ _/_/ _/_/ _/_/ _/_/ "Things are not so easy" _/_/ _/_/ _/_/ _/_/ _/_/ _/_/ "My name is Dump, Core Dump" _/_/_/ _/_/_/ _/_/ _/_/ "El amor es poner tu felicidad en la felicidad de otro" - Leibniz

Is there a way to hide the top level virtual IMAP folder when using the virtual plugin?
by Robert L Mathews 24 Dec '19

24 Dec '19

I'm experimenting with the Virtual plugin to give users access to folders like "All Mail", "Recent" and so on, similar to Gmail. Something like this works properly: mail_location = maildir:~/ namespace { inbox = yes location = prefix = INBOX. separator = . type = private } namespace { prefix = INBOX.virtual. separator = . location = virtual:virtual list = children ignore_on_failure = yes } I can then create "virtual/All Mail/dovecot-virtual" and "virtual/Recent/dovecot-virtual" in the maildir directory, and it works. However, when accessed using IMAP, an IMAP folder named "virtual" shows in the folder hierarchy, with "All Mail" and "Recent" descended from "virtual". It looks like: INBOX Drafts Sent Trash virtual All Mail Recent I'd prefer the virtual folders to be a level up the hierarchy without the "virtual" parent visible, like: INBOX All Mail Drafts Recent Sent Trash Is that possible? I've tried changing the "prefix = INBOX.virtual." on the virtual namespace to just "prefix = INBOX.", but that causes a "Duplicate namespace prefix" error. I also tried using "alias_for" to merge the namespaces, but that causes "namespace configuration error: Namespace virtual. can't have alias_for=INBOX. to a different storage type (virtual vs maildir)". -- Robert L Mathews

When is a new mail not unseen?
by Philip Colmer 24 Dec '19

24 Dec '19

I'm trying to diagnose a really strange situation where certain emails, when submitted to the mailbox by Postfix, are not considered to be unseen by Dovecot. During testing, I've shut down anything else on the server that might want to access the mailbox. I submit the email to the local postfix instance which then says it has delivered it to the mailbox: Dec 23 09:51:35 ip-10-35-194-108 postfix/smtpd[3283]: connect from localhost[127.0.0.1] Dec 23 09:51:35 ip-10-35-194-108 postfix/smtpd[3283]: 5A0BF40261: client=localhost[127.0.0.1] Dec 23 09:51:35 ip-10-35-194-108 postfix/cleanup[3286]: 5A0BF40261: message-id=<20191223095135.5A0BF40261(a)servicedesk.linaro.org> Dec 23 09:51:35 ip-10-35-194-108 postfix/smtpd[3283]: disconnect from localhost[127.0.0.1] ehlo=1 mail=1 rcpt=1 data=1 quit=1 commands=5 Dec 23 09:51:35 ip-10-35-194-108 postfix/qmgr[1660]: 5A0BF40261: from=< philip.colmer(a)linaro.org>, size=702, nrcpt=1 (queue active) Dec 23 09:51:35 ip-10-35-194-108 postfix/local[3287]: 5A0BF40261: to=<local-it-support@localhost>, relay=local, delay=0.06, delays=0.04/0.02/0/0, dsn=2.0.0, status=sent (delivered to mailbox) Dec 23 09:51:35 ip-10-35-194-108 postfix/qmgr[1660]: 5A0BF40261: removed I then use this command to query the state of the mailbox: sudo doveadm mailbox status -u local-it-support all INBOX and get this response: INBOX messages=142 recent=0 uidnext=5596 uidvalidity=1455577845 unseen=0 highestmodseq=1163 vsize=11315688 guid=2a997739f55ac2560d180000e171d23e firstsaved=1577094051 What can be happening that means that Dovecot doesn't treat a newly delivered message as unseen?

Sieve vacation not getting enough headers "no known (envelope) recipient address found in message headers"
by Marc Roos 24 Dec '19

24 Dec '19

I am getting these errors[1]. With fairly default setup where sendmail is delivering mail via lmtp. Adding these, do not seem to make a difference. Should I add something to the sendmail configuration? sieve_vacation_dont_check_recipient = no sieve_vacation_use_original_recipient = no [1] discarding vacation response for implicitly delivered message; no known (envelope) recipient address found in message headers

Trouble using reverse dsync backup (log in successful but almost nothing happens)
by Gerben Wierda 23 Dec '19

I am migrating an old dovecot 2.2.30 (macOS High SIerra, macO S Server) to a new server with dovecot 2.3.7 (macOS Mojave, macports).

Is it safe to mix dovecot import/backup/sync between dovecot versions 2.2.30.2 and 2.3.7.1?
by Gerben Wierda 22 Dec '19

22 Dec '19

I am migrating a server. The old one uses dovecot 2.2.30.2 and the new one 2.3.7.1. I don’t want to use any tool that might influence flags on messages. I am using Maildir format on both ends and I have a way to let one server access the data on the other (either using an rsync or a direct access). Could I set up a sync between both to create a smooth migration?

dovecot rejecting connects
by Roy 22 Dec '19

22 Dec '19

I am a newbie to dovecot but not postfix and centos I created a new VM with Centos 8 and installed dovecot and postfix. Postfix is working fine but dovecot rejects connections from anything but the local machine. Locally Trying 10.10.100.157... Connected to 10.10.100.157. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=PLAIN] Dovecot ready. Machine on same subnet. Windows, Linux, etc. Doesn't seem to matter telnet 10.10.100.157 143 Connecting To 10.10.100.157... Could not open connection to the host, on port 143: Connect failed I made sure the iptables are empty so it doesn't seem to be a firewall issue I put some LOG statements in the iptables and it showed the connect packet arriving and the response packet was ICMP type 3 code 13. Any ideas? Roy

unable to edit wiki 2, here's the edit:
by Steve Newcomb 19 Dec '19

In https://wiki.dovecot.org/Migration/Courier , mail_location = maildir:~/Maildir namespace { prefix = INBOX. separator = . inbox = yes } ... is wrong. Apparently it should be ... mail_location = maildir:~/INBOX ...which at least seemed to work, although (by that time?) I wound up re-downloading all mail. Steve Newcomb srn(a)coolheads.com (Unable to edit the wiki page... Mysterious question stood in the way, something like, "How do you prevent spam?" Evidently I don't know the correct answer.

slow logins over login_trusted_network
by Wojciech Puchar 18 Dec '19

18 Dec '19

i've upgraded dovecot on my server to 2.3.9 works properly but saslauthd that uses it for rimap authentication over 127.0.0.1 works SLOW. You need to wait 15-20 seconds before authentication. only imap login over 127.0.0.1 is slowed down, while over any other IP is quick. i had this problem with older version of dovecot but it was about adding login_trusted_networks = 127.0.0.1 but i already have this and logins is slow. how to disable throttling (or better - put other limits) for 127.0.0.1?
