Dovecot path separator clarification
by Davide Marchi 15 Dec '17

15 Dec '17

Hi Friends, On Debian Jessie and Dovecot 1:2.2.x using the default separator "/" (simply leave commented 10-mail.conf -> "#separator =") I've create for a vuser (from client) a subfolder Scuola/prova on server side, Dovecot create: ../Maildir/.Scuola.prova Here my question: why not ../Maildir/Scuola/prova ? Where I'm wrong? Many thanks! Davide

Why not make: contains "X-Spam-Status" "YES" a single string: contains "X-Spam-Status: YES" that would be more precise and avoid this issue.

Well, I've read the dsync documentation, but this warning has me a little worried: "Make sure destination is exactly as source, deleting/reverting any changes in destination if necessary" So I followed the Imapsync way, and all works fine. I seem to have understood thatImapsync works as a traditional client,for this reason also much easier to use and with less mistakes risk. And anyway a software done very well ;-) x9p wrote:> I do not believe imapsync has license issues. Its written in perl and its > hosted on github.

sieve filter move wrong email to Junk folder
by Gao 15 Dec '17

15 Dec '17

I use a sieve filter to move spam email to user's Junk folder: # cat spam_to_junk.sieve require "fileinto"; if exists "X-Spam-Status" { if header :contains "X-Spam-Status" "YES" { fileinto "Junk"; stop; } else { } } if header :contains "subject" ["SPAM?"] { fileinto "Junk"; stop; } Most time this filter works fine but occasionally it move non-spam in to Junk folder. Here is an example, this email is from dovecot mailling list and it end up in my Junk folder. Mailllog and header here. Would someone help me to figure out what went wrong here? Thanks.

doveadm log reopen not works with 2.2.33
by Alessio Cecchi 14 Dec '17

14 Dec '17

Hi, after the upgrade from dovecot 2.2.32 to 2.2.33 we notice that the /var/log/director/director.log was empty and the log are write in the logrotate file es. /var/log/director/director.log-20171201. Log path is dovecot is: log_path = /var/log/director/director.log Logrotate configuration is: /var/log/director/director.log { daily rotate 31 missingok notifempty compress delaycompress sharedscripts postrotate doveadm -i director log reopen endscript } and worked fine until the last dovecot upgrade. Now the only way to "reopen" the log file is doveadm reload. Is this a know bug? Thanks -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice

Just to be clear, if at any point your VPS has access to the plaintext mail (or keys that decrypt mail), then the VPS provider could access your decrypted mail. To make it unfeasible for your VPS to read your mail, it has to arrive at your VPS pre-encrypted. I can envision a system where you import encrypted mail into your mail store, then use client IMAP access to be decrypted locally by your mail reader. However, metadata is still accessible by your VPS provider. If your VPS is the MTA that directly handles SMTP from your correspondees sending you unencrypted messages, you can't lock out a sufficiently skilled platform admin.

TLS Error and not working lmtp
by Jakob Schürz 13 Dec '17

13 Dec '17

Hi! I have some troubles with the virtual plugin. I run a self-compiled dovecot 2.2.33.2 from debian testing. I patched this version with the QRESYNC-Patch from a few weeks ago. But i always get an errormessage, when i try to open an email from a virtual mailbox. So i cloned the actual git-Repo and compiled dovecot and pigonehole-sieve. The problem with the virtual plugin seems gone away. But there are some other problems. I use ssl=required and with dovecot from debian TLS/SSL and STARTTLS works fine. With the selfcompiled from git, i get this error: dovecot[1284]: imap-login: Error: Failed to initialize SSL server context: Couldn't parse DH parameters: error:0906D06C:PEM routines:PEM_read_bio:no start line: Expecting: DH PARAMETERS: user=<>, rip=127.0.0.1, lip=127.0.0.1, secured, session=<D6bC4Rlg8ut/AAAB> The key and crt are exactly the same files as before. The second problem is, lmtp is not working. I use exactly the same config for the debians dovecot and dovecot from git. But in the gitversion the error in exim is: Failed to connect to socket /var/run/dovecot/lmtp for dovecot_lmtp transport: Connection refused My config is: # dovecot -n # 2.3.devel (b1aac3a1d):

Recommended tool for migrating IMAP servers
by Davide Marchi 12 Dec '17

12 Dec '17

Hi Friends, I would like to ask you a suggestion: I need to migrate a imap server to a new one and then dismiss the old one. Reading from relative Dovecot documentation page (https://wiki.dovecot.org/Migration) more tools are shown: UW-IMAP's mailutil, imapsync, YippieMove and Larch. The each mail servers are Linux based, one of this (mine) is Dovecot. Based on your experience which of these tools would be preferable to use? Thank you very much Davide

Re: hosting emails at home

Hello Mike, Yes, I am using a static IP address, but in theory, you could use a dynamic one. Nothing technically would prevent email exchanges between two boxes, as long as the SPF records are up to date and the DKIM is properly setup. Unfortunately, some ISPs are simply blacklisting full range of private IP addresses just because they are not officials / commercials.

hosting emails at home
by André Rodier 11 Dec '17

11 Dec '17

Hello everyone, I have been using Postfix and Dovecot for my personal emails for years. After being tired of reinstalling my personal mail server many times, I am currently writing some Ansible scripts to do it automatically. I obviously checked the other projects, and did not found anything close to what I am looking for, so I am implementing it now. The final goal is to have a box that once online, would setup itself, by creating the certificates, the DKIM keys and update the appropriate DNS records. This is so far what I have achieved: - Automatic generation of certificates using LetsEncrypt - Automatic update of the domain entries: imap, smtp, webmail, etc. - Automatic generation of a DKIM keys - Automatic update of specific records (MX, SPF, DKIM, etc.) - LDAP server for user accounts, with or without system login. - Installation of Postfix, Dovecot and Roundcube Sending DKIM signed emails is working, and the IMAP server is configured as well, although basic. The postfix and dovecot configuration are not yet entirely finished. I am planing to add an anti spam system, and sieve, amongst other things. Although in development during my spare time, the system is normally robust and you should be able to run it multiple times without errors. If anyone is interested to use it, to have a look, or to take part, it is here: https://github.com/progmaticltd/homebox Kind regards, André Rodier.

iPhone no longer authenticating

I've switched a user to being an active directory user. That user's email client authorizes just fine with dovecot using GSSAPI. However, now his iPhone won't authorize. In the dovecot log file I get: Dec 01 14:27:28 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=q4n3W0xfggBiZj9s lip=98.102.63.107 rip=98.102.63.108 lport=993 rport=49538 resp=AG1wcmVzcwBEaW5va3JvbndhbGw0NQ== (previous base64 data may contain sensitive data) Dec 01 14:27:32 auth-worker(5988): Debug: shadow(mpress,98.102.xx.yyy): lookup Dec 01 14:27:32 auth-worker(5988): Info: shadow(mpress,98.102.xx.yyy): unknown user (given password: *******) Dec 01 14:27:34 auth: Debug: client passdb out: FAIL 1 user=mpress Dec 01 14:27:34 imap-login: Info: Aborted login (auth failed, 1 attempts in 6 secs): user=<mpress>, method=PLAIN, rip=98.102.xx.yyy, lip=98.102.63.107, TLS, session=<q4n3W0xfggBiZj9s> Dec 01 14:27:34 imap-login: Debug: SSL alert: close notify [98.102.xx.yyy] This same user will authenticate OK from his local domain workstation: Dec 01 14:28:52 auth: Debug: master userdb out: USER 1948516353 mpress system_groups_user=HPRS\mpress uid=10005gid=10000 home=/home/HPRS/mpress auth_token=ce3050035718ed0996af698400c4de1be453ec06 auth_user=mpress(a)HPRS.LOCAL Dec 01 14:28:52 imap-login: Info: Login: user=<mpress>, method=GSSAPI, rip=192.168.0.54, lip=192.168.0.2, mpid=9755, TLS, session=<6MT1YExftwDAqAA2> I'm pretty sure the reason has to do with Active Directory authenication locally, but of course his iPhone is not a member of the domain, and he is no longer in /etc/passwd/shadow.

I'm looking into ways to encrypt the stored email on my server. The idea is to make it impossible for my hosting provider (who has access to my VPS) to read the mail from the disk. So I'm looking into ways to do this, and I found the mail-crypt plugin for dovecot. Unfortunately I find the documentation very hard to understand. There is no clear description of what the goal and purpose of the plugin is, or how it works. Most of the documentation is very short and provides no explanation. So here are some questions - I will gladly help to update the documentation when some of these questions are answered :) If you cannot answer them all, please tell me what you know.. - It seems mail-cypt will transparently encrypt/decrypt mail - so it stores it on the server in encrypted form, but dovecot serves it unencrypted over IMAP. Is this correct? - It seems that mail-crypt needs both a private and a public key to work. Is this correct? - If mail-crypt has both private and public key in its configuration, does that not defeat the purpose of the whole thing? Anyone with access to the disk will be able to read everything? Regarding the settings: mail_crypt_global_private_key(_n) - Private key to decrypt files, you can specify many mail_crypt_global_public_key - Public key to use to encrypt files, you can specify one - How does this work? What does mail-crypt do when multiple private keys are specified? mail_crypt_private_key - Private key to decrypt user's master key, can be base64 encoded mail_crypt_private_password - Password to decrypt user's master key or environment private key - What is the relation between a users master key, and the private/public global keys above? What is an environment private key? TIA, and as I said above, I will help with updating the docs! -- Sent from: http://dovecot.2317879.n4.nabble.com/

Steffen Kaiser > Hmm, this is a job for: > > https://wiki2.dovecot.org/Plugins/Snarf Cool! Can this be used with the imapc: driver to consolidate mail from separate IMAP accounts into one? (Sort of like how you can configure Gmail to slurp up mail into the Gmail account.) Joseph Tam <jtam.home(a)gmail.com>

Use multiple mbox locations
by bapt x 08 Dec '17

Hello, With GNU mailutils on Debian 9, we receive mails in /var/mail/<username> but when we read mails with the "mail" command, they are moved in a file ~/mbox: "Saved 1 message in /home/<username>/mbox". I use Roundcube webmail with Dovecot but if I also use use the "mail" command to read emails, Roundcube will not display old messages anymore since they were moved to ~/mbox. So is their a way to tell Dovecot that we want to lookup for emails both in /var/mail/<username> and ~/mbox? I saw https://wiki.dovecot.org/Namespaces#Mixed_mbox_and_Maildir but I it did not work if when I tried to add 2 times a mbox location. Thanks for your help.

Errors and dovecot crashing...
by SH Development 06 Dec '17

Our production dovecot/postfix server has been stable for a number of years. In the last month or so, we are seeing increasing errors such as these: Dec 6 15:51:20 mail dovecot: imap(redacted(a)lilythicket.com): Warning: Transaction log file /home/vmail/lilythicket.com/diana/Maildir/dovecot.index.log was locked for 322 seconds Dec 6 15:50:54 mail dovecot: imap(redacted(a)theormans.com): Warning: Maildir /home/vmail/theormans.com/connieorman/Maildir/.Junk: Synchronization took 66 seconds (1 new msgs, 0 flag change attempts, 0 expunge attempts) Dec 6 15:51:43 mail dovecot: master: Error: service(pop3-login): Initial status notification not received in 30 seconds, killing the process Dec 6 15:51:43 mail dovecot: master: Error: service(pop3-login): command startup failed, throttling Dec 6 15:51:43 mail dovecot: master: Error: service(imap-login): child 5868 killed with signal 9 Dec 6 15:51:43 mail dovecot: master: Error: service(imap-login): command startup failed, throttling Dec 6 15:55:31 mail dovecot: imap-login: Fatal: Corrupted SSL ssl-parameters.dat in state_dir: Truncated file Dec 6 15:55:32 mail dovecot: pop3-login: Fatal: Error reading configuration: Timeout reading config from /var/run/dovecot/config And so forth. Seems to be all over the place. The server slows down to a crawl. Restarting dovecot or postfix has no effect on the problem. Only a server reboot solves it, temporarily. Sometimes for weeks, sometimes for hours. The hard drive SMART status reads okay. During this time, of course, users cannot connect to check their email. Thoughts on where to go to troubleshoot this and why it’s happening? Ethon

I've been playing with this ldap authentication for a couple of years off and on. Time isn't a problem. The issue with setting up a test environment is that I really need the domain workstations and external smartphone attempting to connect when I make a change so I can follow what's going on in the Dovecot log and maillog. It's rather simple to test a change, then put things back. I'll likely not go the test platform route for now, but thanks for the input. > > Your example is not the complete dovecot-ldap.conf.ext file, right?

I just provided the essentials. > [deleted] Ok, here's what I've come up with for dovecot-ldap.conf.ext hosts = mail.hprs.local base = dc=mail, dc=hprs, dc=local ldap_version = 3 scope = subtree deref = never debug_level = -1 auth_bind = yes auth_bind_userdn = %n@dom dn = cn=Administrator,cn=users,dc=hprs,dc=local dnpass = ******* user_filter = (&(objectclass=person)(sAMAccountName=%n)(!(userAccountControl=514))) pass_filter = (&(objectclass=person)(sAMAccountName=%n)(!(userAccountControl=514))) I've enabled auth-ldap.conf.ext in 10-auth.conf. My doveconf is listed at bottom. Unfortuntately, this doesn't work. My remote devices are not even showing as trying to connect. For internal domain LAN users I get: Dec 06 01:08:10 imap-login: Info: Disconnected: Auth process broken (disconnected before auth was ready, waited 30 secs): user=<>, rip=192.168.0.52, lip=192.168.0.2, session=<3/ZyxaVfE8PAqAA0> I do see ldap listening on 389, imap[s] (Dovecot) listening on 143 and 993, these last two are opened externally through the firewall. > For the rest: my advise is that you *really* need to pay around with > this much more.

I've got internal AD authentication working with GSSAPI and I've got a rather complex checkpassword program able to do authentication, so I don't think I'm a complete moron, although this project makes me feel that way. Now, I just want smartphones to authenticate with their owners' domain credentials and get them out of /etc/passwd. I believe I've read all the Dovecot wikis on ldap plus things from many other sites. I've been to that howtoforge site before. It mostly deals with setting up Postfix, which I'm not using. The dovecot bits make more sense in light of your feedback. I've tried that ldapsearch example: ldapsearch -x -h ad.example.com -D 'vmail' -W -b 'cn=users,dc=example,dc=com' with the domain user I specified in my dovecot-ldap.conf.ext with my host and dc info and I get the error ldap_bind: Strong(er) authentication required (8) additional info: BindSimple: Transport encryption required. I've seen confusing postings on this error having to do with port 636 and LDAPS -- no idea what they're talking about. My user is the Samba/domain administrator and has a pretty complex password. None of the sites I've visited on this error indicate it has anything to do with the actual password's complexity. Perhaps I'm just thick-skulled with all this. If you or anyone can see something obviously wrong with my conf, or have any suggestion at all on a baby step I can take to incm me forward, please let me know.
