dsync: expunge from pop3 does not replicate
by Jakub Lánský 25 Jul '18

25 Jul '18

Hi, I'm using dovecot 2.3.2.1 on Xenial from upstream packages on two Dovecot servers connected with dsync over TCP. E-mails which are deleted via POP3 protocol are not correctly deleted on second server via dsync. Jul 25 09:29:19 mda11 dovecot: pop3(jakub@***)<7587><8xaJ1c1x9uEqAB7QADwAAAAAAAAAAL7v>: expunge: box=INBOX, msgid=<6a75db5d84ff257216a4340d7c0405b2(a)blesmrt.eu>, size=3238, from=lenny@***, subject=dovecot pop3 test Nothing happened on the second machine then. After running # doveadm replicator replicate "jakub@***", e-mail got expunged immediately on second server.

Dsync fails to connect to remote IMAP server
by Andrzej Polatyński 24 Jul '18

Hi, I'm trying to migrate from an old courier IMAP server to Dovecot 2.3.1 (8e2f634). The old server uses self signed SSL certificate. I'm using the following configuration: imapc_host = 10.1.1.3 imapc_user = %u imapc_features = rfc822.size fetch-headers imapc_port = 993 imapc_ssl = imaps imapc_ssl_verify = no mail_prefetch_count = 20 mail_shared_explicit_inbox = no Launching dsync with the command: doveadm -o mail_fsync=never -o imapc_password=PASSWORD -Dv backup -R -u USER @DOMAIN <andrzej(a)datatel.net> imapc: In the output logs I get messages like below: dsync(USER@DOMAIN): Error: imapc(10.1.1.3:993): Couldn't initialize SSL context: Can't verify remote server certs without trusted CAs (ssl_client_ca_* settings) dsync(USER@DOMAIN): Debug: imapc(10.1.1.3:993): Created new connection dsync(USER@DOMAIN): Debug: imapc(10.1.1.3:993): Looking up IP address (reconnect_ok=true, last_connect=1532016643) dsync(USER@DOMAIN): Debug: imapc(10.1.1.3:993): Connecting to 10.1.1.3:993 dsync(USER@DOMAIN): Info: imapc(10.1.1.3:993): Connected to 10.1.1.3:993 (local 172.17.0.5:51972) dsync(USER@DOMAIN): Error: imapc(10.1.1.3:993): No SSL context dsync(USER@DOMAIN): Debug: imapc(10.1.1.3:993): Disconnected Am I missing some configuration parameters? -- Regards, Andrew

dovecot sometimes sends non-default SSL cert if IMAP client won't send SNI
by Martin Johannes Dauser 24 Jul '18

24 Jul '18

Hi, I recognised some funny behaviour on my server. IMAP clients which won't send an Server Name Indication (SNI) sometimes get the wrong certificate. I would expect that those clients always get the default certificate (of my new domain), instead in about 20 to 50% of connections the certificate of my old domain will be presented. (sample rate was 3 times 30 connections) Clients sending SNI always get the right certificate. A user informed me that offlineIMAP complains 'CA Cert verifying failed: no matching domain name found in certificate' So at least offlineIMAP 7.0.12 from Debain stretch won't send SNI, there is a newer version upstream though. I myself checked the server's behaviour with openssl: $ openssl s_client -showcerts -connect IP-address:993 and $ openssl s_client -showcerts -connect IP-address:993 -servername imap.domain I'm totally clueless about how come.

Namespace question
by J Doe 24 Jul '18

24 Jul '18

Hi, I have a question about the “inbox” namespace, as mentioned in: conf.d/10-mail.conf. I have written my dovecot.conf file from scratch and do not include: conf.d/10-mail.conf. I have not defined the “inbox” namespace and so I am assuming that one is created by default. When I list the dovecot defaults via “sudo doveconf -d”, I notice that no “namespace inbox” entry exists. If “namespace inbox” is not specified, is one still created by default ? Thanks, - J

23 Jul '18

Has anvil gone away in 2.3.2.1? I ask only because I don't find an example of anvil in the conf.d files anymore and I'm migrating from 2.2.10 version to 2.3.2.1. Thanks.

Dovecot pop3d and imapd problem
by John Paul Iglesia 23 Jul '18

23 Jul '18

Hi, My dovecot version : 2.2.22 Recently, i had issues on dovecot. All packages of dovecot were installed on my system then suddenly when I checked yesterday the packages for dovecot-pop3d and dovecot-imapd were no longer on the list of app installed. Because of this dovecot service stop running. I checked the apt history log, term log and even dpkg log, there were no information about removing the packages. It just shown on my apt list the packages were not longer there. I had to reinstalled these 2 packages just to make dovecot run and for me to be able to receive and send messages. What do you think is the problem, is it dovecot bug? Please advise. Thanks, paul.tcbc

Stopping login via "nologin" parameter
by J Doe 23 Jul '18

23 Jul '18

Hello, I have a basic e-mail server with Postfix 3.1 and Dovecot 2.2.22. I am using a passwd-file for both userdb and passdb: /etc/dovecot/dovecot.conf userdb { driver = passwd-file args = /etc/dovecot/passwd } passdb { driver = passwd-file args = /etc/dovecot/passwd } } In the passwd file, I want to have user account names for SMTP SASL AUTH and IMAP that are NOT e-mail addresses. For example, employee one of ABC corp would have a SMTP SASL AUTH/IMAP account name in the form: abc_company_employeeid (for example: abc_company_03284). The idea behind that is that I do not want someone outside of the company to be able to know the first half of the username and password pair just because they have an employee's e-mail address. For the e-mail address I specify something like: bob(a)abc.com however I never want someone to be able to login via their e-mail address. Originally, I specified the password field as empty, with the understanding being that the default encryption of a password is {CRYPT}. Since crypt() cannot output a null string, this meant that there was never a valid password. So passwd looked like this: /etc/dovecot/passwd # SMTP SASL AUTH and IMAP accounts abc_company_03284:::::::userdb_mail=maildir:/var/mail/vhosts/abc.com/abc_co… # IMAP bob@abc.com:vmail:vmail::/home/vmail/bob::userdb_maill=maildir:/var/mail/vhosts/abc.com/abc_company_03284 I tested SMTP SASL AUTH and IMAP via the openssl s_client and can confirm that I can login and send e-mail as well as retrieve mail only via the: abc_company_03284 account, but because an empty password field isn’t mentioned on the Dovecot wiki, I was wondering if I should add “nologin” to explicitly make it impossible for: bob(a)abc.com. “nologin” was mentioned to me in a previous e-mail to this list. So passwd would now look like this: /etc/dovecot/passwd # SMTP SASL AUTH and IMAP accounts abc_company_03284:::::::userdb_mail=maildir:/var/mail/vhosts/abc.com/abc_co… # IMAP bob@abc.com:vmail:vmail::/home/vmail/bob::userdb_mail=maildir:/var/mail/vhosts/abc.com/abc_company_03284 nologin I restarted Dovecot and tested this with openssl s_client for SMTP SASL AUTH and IMAP, but just wanted to make sure that this STOPS ANY LOGINS via the e-mail address: bob(a)abc.com ? Thanks, - J

I've installed LE certs on my Dovecot a while back, and, it has been working OK since, but, today, an iPhone user said he can't get emails as iphone says 'cert is expired', searching around, I see some other iPhone similar issues reported, do I have my conf correct, I have; # cat dovecot.conf | grep ssl ssl = required verbose_ssl = no ssl_cert = </etc/letsencrypt/live/fqn.myserver/fullchain.pem ssl_key = </etc/letsencrypt/live/fqn.myserver/privkey.pem is fullchain.pem and privkey.pem is what I should be using ? anythought how to force an iphone to reload cert ? actual cert was renewed 15/7, old/previous one expired earlier today ls /etc/letsencrypt/live/fqn.myserver/ cert.pem chain.pem fullchain.pem privkey.pem (if I open mailserver host in browser, padlock shows current/valid cert) -- Voytek

20 Jul '18

Hello, I use dovecot with dbox storage system. Today I receive 2 mail (I see that in the maillog ) but I don't find in INBOX using my IMAP client. I look in the files m.* and I find the message that I receive. But I cannot find it in any IMAP folder. I try to run "doveadm force-resync -u user inbox" but nothing change. I export all email using the command "doveadm backup -u user mbox:/tmp/mail:INDEX:/tmp/imap:LAYOUT:maildir++ and in the mbox file for inbox I found the 2 mails arrived. How I can understand why I cannot see the messages ? or how I can recover it ? Bet regards.

OT: 'lost' emails
by Voytek 20 Jul '18

20 Jul '18

I suspect this is mail client issue, but looking for any suggestions: user with Thunderbird says " I'm losing emails, mail is not in inbox, but, when I search, that email shows in search result, but, I can't open the email body" i don't fully understand what he was trying to say, and, won't be able to look at his PC till Monday. Looking at inbox's 'cur' directory, I can see the'missing' email amongst the other 2000 emails in 'cur' Is there any indexing I should do on the user's email folder, how? or, is this purely Thunderbird issue, and, I need to re index Thunderbird? V -- Sent from my Android device with K-9 Mail. Please excuse my brevity.

SIS: dovecot creates duplicated attachments (sometimes)
by Alexander Moisseev 20 Jul '18

20 Jul '18

SIS deduplication was broken in 2.2.16 and has been fixed with https://github.com/dovecot/core/commit/3b39022ea0513363241cf852b7d454c84158… but still sometimes (just several times in a month or so) dovecot creates duplicated attachments. As you can see in directory listings below all attachments was created at (about) the same time, but one of them has different inode number.

folders not visible on copied mail folders
by Mark Foley 20 Jul '18

20 Jul '18

We had a user quit recently. Three days ago I copied his entire Maildir folder to another user to that user's Maildir/.JoesEmail. I changed ownership and made the permission 'chmod -R og-rwx .', just like all the other files/directories of the new owner. This didn't work to show the new folder. Today, in his Thunderbird client, I subscribed to the 'JoesEmail' folder. I restarted dovecot and restarted Thunderbird. In Thunderbird, the 'JoesEmail' folder now shows, but it is empty and shows none of the subordinate mail folders. I ran 'doveadm index -u newowner JoesEmail' and 'doveadm force-resync -u newowner JoesEmail'. This didn't help. I did this once before with a previous user who quit and only changed ownership, no subscribing, no doveadm, and that worked. What am I doing wrong? THX --Mark

100% Dovecot MTA Replacement Setup
by David Favor 19 Jul '18

19 Jul '18

Working out upgrade of old 1.x + 2.x Dovecot installs to latest 2.3.2.1 out of Ubuntu Bionic repositories. _______ https://wiki.dovecot.org/Services suggests Dovecot can be used for full mail infrastructure, avoiding the complexity of exim4 or other MTA setup/management. Let me know if I understand this correctly. 1) https://wiki.dovecot.org/Submission can be used to listen on port 25 + port 587 (with auth). 2) https://wiki.dovecot.org/Pigeonhole can be used for filtering, including forwarding email to other machines. 3) https://wiki.dovecot.org/Pigeonhole/ManageSieve/Configuration can be used to forward off machine email, for example flowing through a relay service like MailGun, using a simple script or service like ESMTPD. 4) https://wiki.dovecot.org/LMTP can be used to deposit messages into filesystem as Maildir or dbox or mdbox backing stores.

Replication problems
by Thomas Kristensen 19 Jul '18

19 Jul '18

Hey I am trying to setup a dovecot cluster with 2 servers using replication /dsync. In front of it I got a Fortinet ADC (Load balance) and I think that I messing up the dsync. I see mails duplicated in the sync progress. If I disable one of the servers in the ADC, it seems to work and the sync if working without a problem. But if I use both servers with a round robin on the ADC, I see mailed duplicated. Ex. I sent 100 mails thru the SMTP (Postfix) and 107 mails is in both servers, but as said before, if I disable one of the servers in the ADC, I see the correct amount of mails in both dovecot servers. In the header of the duplicated mails I see the exact same postfix id and LMTP id from dovecot. Also I cant seem to get any log from the sync progress.

Re: Sendmail Dovecot Trouble
by John Rowan 19 Jul '18

19 Jul '18

/var/mail is a symlink to /var/spool/mail I tried both, neither works. I just wiped out the server, reinstalled from scratch this time I selected e-mail server while selecting packages after specifying GUI-server on the CentOS install. I had previously installed Dovecot after the initial server build. This time Dovecot was installed and active at boot but still can't find my mail in /var/spool/mail.

Having reinstalled CentOS 7 including e-mail server in initial software configuration it installed Postfix/Dovecot. I've been using Sendmail for 20 years and no experience with Postfix. Looked in Webmin -> servers -> Postfix and specified Maildir, changed the 10-mail.conf to specify mail_location = maildir:~/Maildir and everything's working. Thanks for help.

best practices for migrating to new dovecot version
by Shawn Heisey 18 Jul '18

18 Jul '18

I have a machine with my mail service on it running Debian Squeeze. The version of dovecot on that server is 1.2.15. I'm building a new server with Ubuntu 18.04 (started with 16.04, upgraded in place), where the dovecot version is 2.2.33. I plan to migrate all my services to this new machine. The virtual mailboxes are on disk in maildir format, with accounts in a mysql database managed by postfixadmin. When I copy them over to the new machine, would there be any value to excluding the files that dovecot creates, and letting the new version recreate them? In one mailbox here are some of the files I am considering excluding: dovecot.index dovecot.index.cache dovecot.index.log dovecot.index.thread dovecot-keywords dovecot-uidlist dovecot-uidvalidity dovecot-uidvalidity.5876ca77 There are other files under consideration, like maildirsize and maildirfolder. One that I would be sure to *not* remove is subscriptions. If there are recommendations about dovecot files in a maildir that should not be removed during a migration, please let me know. I'm aware that rebuilding this information could be slow. My own personal mailbox on the system is over 8GB in size and has well over nine hundred thousand files in it. Thanks, Shawn

Dovecot Quota and subject utf-8

18 Jul '18

Hi. When a user is over quota and a message is rejected, it sends a message back changing partially the subject (depending on the size). With utf-8 it breaks the information, we noticed this behavior when the subject line uses utf-8 and it is broken in more than one line: Subject: Quêm casé erat vim id, vix ín dicit putânt, minim çónsequuntur ea iús. Agam cetêro tê eôs, ád vim ipsum tantâs expetêndis.
