Hi, I use Dovecot 2.2.32 I just migrated spool from another server (by copying filesystem, I use maildir), this is an example of mailbox's content: drwx------ 20 postfix postfix 30 Oct 4 18:38 . drwx------ 3 postfix postfix 3 Nov 16 2012 .. drwx------ 5 postfix postfix 11 Jun 19 18:22 .Deleted Items drwx------ 5 postfix postfix 11 Sep 29 09:27 .Drafts drwx------ 5 postfix postfix 9 Oct 4 10:18 .INBOX.Drafts drwx------ 5 postfix postfix 9 Oct 4 10:18 .INBOX.Sent drwx------ 5 postfix postfix 9 Oct 3 18:01 .INBOX.Trash drwx------ 5 postfix postfix 12 Sep 29 09:27 .Junk drwx------ 5 postfix postfix 8 Dec 9 2014 .Junk E-mail drwx------ 5 postfix postfix 8 Nov 11 2015 .Archive drwx------ 5 postfix postfix 9 Oct 2 14:18 .Posta indesiderata drwx------ 5 postfix postfix 9 Jun 19 18:22 .Posta inviata drwx------ 5 postfix postfix 10 Oct 4 12:27 .Sent drwx------ 5 postfix postfix 10 Oct 4 18:01 .Trash drwx------ 2 postfix postfix 215 Oct 4 18:00 cur -rw------- 1 postfix postfix 53 Feb 16 2017 dovecot-keywords -rw------- 1 postfix postfix 13963 Oct 4 16:45 dovecot-uidlist -rw------- 1 postfix postfix 8 Oct 3 18:01 dovecot-uidvalidity -r--r--r-- 1 postfix postfix 0 Nov 27 2015 dovecot-uidvalidity.5658162a -r--r--r-- 1 postfix postfix 0 Sep 27 18:18 dovecot-uidvalidity.59cbcf5c -rw------- 1 postfix postfix 7200 Sep 29 01:19 dovecot.index -rw------- 1 postfix postfix 63336 Oct 4 18:00 dovecot.index.cache -rw------- 1 postfix postfix 6436 Oct 4 18:38 dovecot.index.log -rw------- 1 postfix postfix 216 Oct 3 18:01 dovecot.mailbox.log drwx------ 2 postfix postfix 2 Oct 4 16:45 new -rw------- 1 postfix postfix 96 Oct 3 18:01 subscriptions drwx------ 2 postfix postfix 2 Oct 4 16:12 tmp and this is my Dovecot's conf: auth_mechanisms = plain login digest-md5 cram-md5 disable_plaintext_auth = no first_valid_gid = 125 first_valid_uid = 125 mail_gid = 1003 mail_location = maildir:/var/spool/virtual/domains mail_privileged_group = postfix mail_uid = 1003 namespace { inbox = yes location = prefix = INBOX. separator = . type = private } namespace inbox { location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } passdb { args = /etc/dovecot/dovecot-sql-crypt.conf.ext driver = sql } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { group = postfix mode = 0600 user = postfix } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } ssl_cert = </etc/ssl/wildcard.domain.net_bundle.crt ssl_key = # hidden, use -P to show it userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql It seems I have duplicate folder (for example during webmail access, I use Roundcube).

STAT command error
by Andrew Charnley 04 Oct '17

04 Oct '17

Hi, Unsure if my previous message made it through as didn't see it on a digest. I'm using Claws Email and 3 of 4 email accounts keep giving; [10:50:45] POP< +OK Dovecot ready. [10:50:45] POP> USER sales [10:50:45] POP< +OK [10:50:45] POP> PASS ******** [10:50:45] POP< +OK Logged in. [10:50:45] POP> STAT [10:50:45] POP< -ERR Unknown command: *** error occurred on POP session *** Error occurred while processing mail. I've turned on as much logging as I can find in Dovecot but nothing useful is coming out, it honestly does believe STAT is invalid - I can see the connection close rather than disconnect. It's strange how it works for one account but not others, the settings are identical - I went through them with a fine tooth comb. Any suggestions appreciated. Regards, Andrew

ACL permission: give permission to move email into different folder
by Davide Marchi 03 Oct '17

03 Oct '17

Hi friends, I've set ACL for two user (two primary email address, no alias), where these users must not be able to delete email from imap server. Now I would like to add (from the client) the ability to move any incoming mail into different directory, if possible into an existing directory chosen by me. These are the settings on /etc/dovecot/dovecot.acl: * user=foo(a)mydomain.com lrwsip * user=info(a)mydomain.com lrwsip is it possible? I've read https://wiki2.dovecot.org/ACL but I've not found a solution. many many thanks! Davide

Postfix + saslauthd SASL With Kerberos (FreeIPA) unable to send mail
by Anvar Kuchkartaev 03 Oct '17

03 Oct '17

Hello I just finished setting up FreeIPA with Dovecot + Postfix + Saslauthd. I can easily access to mails using imap via dovecot with gssapi authentication and postfix also delivering mails very well. But I cannot send email from postfix using gssapi authentication (plain and login authentication working fine) because saslauthd is not specifying realm when requesting service from freeipa domain. warning: SASL authentication failure: GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (No key table entry found matching smtp/mx0.aegisnet.eu@) right form of request is smtp/mx0.aegisnet.eu(a)AEGISNET.EU I googled alot but couldn't find any solution to solve this problem. How to configure saslauthd well that it will use realm to contact with freeipa. Best Regards...

dovecot listening imaps external interface
by David Mehler 02 Oct '17

02 Oct '17

Hello, I'm trying to get dovecot to listen on specific interfaces. On the server itself I've got webmail going so am needing imap on 143. I do not want this on the external server interface, so I am wanting imaps port 993 external only. The configuration looks right, but Dovecot isn't showing anything listening on port 993 at all. Unrelated, my public and shared folders are not working. Can anyone suggest fixes for either of these issues? Thanks.

Quota - frustrated trying to configure ...
by Garry Glendown 02 Oct '17

02 Oct '17

Hi, after fighting Dovecot almost every step of the way, I have finally gotten most of the functions configured on a customer box (used Cyrus on a previous install, but it was dropped from SLES 12 ...) The mail server setup uses LDAP for user authentication, has a central maildir tree (.../dovecot/maildir/<USER>/...) that is used for all users' mail, sieve is also running well. The users themselves are just virtual users, they do not have a local home directory or anything. I was now trying to get Quota to work ... Looking at the Wiki more or less showed the same "spotty" results of the rest of the Wiki. Fine for anybody that needs the documentation just as a reference, but somewhat lacking for someone that does not have experience in setting up Dovecot. I tried following the wiki, as well as checking on other web pages I came across. In order to keep the setup simple, and not have to jump through hoops to set up any SQL backup etc., I tried using a file-based storage of the quota entries, as in: dict { quota = file:/data/dovecot/db/quota.db } I also added quota entries in the other places I believe are necessary, and set up a rule like this: plugin { quota_rule = *:storage=1G quota_rule2 = Trash:storage=+100M } I got through dovecot restart without errors, and IMAP still answers. But attempting to do a recalculation of the current quota usage ends up with this error: doveadm(root): Error: chdir(/root/) failed: Permission denied (euid=479(dovecot) egid=478(dovecot) missing +x perm: /root, dir owned by 0:0 mode=0700) doveadm(root): Error: chdir(/root) failed: Permission denied It looks like dovecot doesn't actually attempt to look at the central maildir, but instead seems to attempt to enter the current user's homedir (which, in this case, is root). What am I (possibly) missing here? Is this way of setting it up even viable? While I need a general per-user-quota, I also need the ability to overwrite each user's default quota ... is there any recommendable more detailed documentation on how to set up quota? Thanks, -garry

[PLUGIN] Virtual keywords (aka Gmail-like labels)
by Daniele Ricci 02 Oct '17

02 Oct '17

Hello list, I'm new here and since I've been working on a plugin lately I though I'd post it here. It's GPL licensed, hosted on GitHub: https://github.com/daniele-athome/dovecot-virtual-keywords-plugin I've been trying to find a replacement for Gmail and I already have my own mailserver. What I'm missing very much is labels. Since folders don't really match labels, I had to implement something that at least resembles them. I decided to use IMAP keywords since it's probably the closest thing to labels. The README in the repository pretty much describes what this plugin do, but basically it creates virtual mailboxes with predefined rules to match for labeled messages. E.g. if you set a "Urgent" keyword on any message, the plugin will create a "Virtual/Urgent" virtual mailbox that will have the message you just labeled. I'm a bit out of practice on C but I believe I managed. I've tested the plugin locally but I've not deployed it on my production mail server yet. I'd like to hear your opinions (reviews and comments are very welcome) and possibly find other people interested in this approach to discuss about it. Thanks! -- Daniele

sieve script not executed?
by Roberto Nunnari 02 Oct '17

02 Oct '17

Hello. I'm trying to set up a vacation autoresponder but up to now, no success. I'm using dovecot managedsieve to set up the new filter and to my understanding it works correctly and it creates in the user's home the link .dovecot.sieve that points to sieve/managesieve.sieve ~$ cat .dovecot.sieve require ["date","relational","vacation"]; # rule:[Vacanza] if allof (currentdate :zone "+0200" :value "ge" "date" "2017-09-29", currentdate :zone "+0200" :value "le" "date" "2017-10-09") { vacation :days 7 :addresses ["robi@hidden1","robi@hiden2"] "eccoci a dopo"; } Problem is that apparently this filter is completely ignored.. that is, when a new email is delivered to those addresses, no autoresponse is sent back to the sender. I also, followed the troubleshooting guide here: https://wiki2.dovecot.org/Pigeonhole/ManageSieve/Troubleshooting and everything works as expected. What is the problem? What am I missing? Thank you and best regards.
