Hello List, I am using dovecot: ii dovecot-antispam 2.0+20130822-2 amd64 Dovecot plugins for training spam filters ii dovecot-core 1:2.2.10-1 amd64 secure POP3/IMAP server - core files ii dovecot-imapd 1:2.2.10-1 amd64 secure POP3/IMAP server - IMAP daemon ii dovecot-ldap 1:2.2.10-1 amd64 secure POP3/IMAP server - LDAP support ii dovecot-lmtpd 1:2.2.10-1 amd64 secure POP3/IMAP server - LMTP server ii dovecot-managesieved 1:2.2.10-1 amd64 secure POP3/IMAP server - ManageSieve server ii dovecot-mysql 1:2.2.10-1 amd64 secure POP3/IMAP server - MySQL support ii dovecot-pop3d 1:2.2.10-1 amd64 secure POP3/IMAP server - POP3 daemon ii dovecot-sieve 1:2.2.10-1 amd64 secure POP3/IMAP server - Sieve filters support doveconf -n | grep -i sieve 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 ihave editheader vnd.dovecot.duplicate sieve = ~/.dovecot.sieve sieve_after = ~/sieve_after sieve_dir = ~/sieve sieve_extensions = +editheader +vnd.dovecot.duplicate sieve_max_redirects = 20 protocols = " imap lmtp sieve pop3" service managesieve-login { inet_listener sieve { mail_plugins = " quota sieve" mail_plugins = " quota sieve" I would like to have a Global and per user based Local sieve_before file. Since doveconf does not indicate I believe my version does not support: sieve_global_path A path to a global sieve script file, which gets executed ONLY if user's private Sieve script doesn't exist, e.g. /var/lib/dovecot/default.sieve. Be sure to pre-compile this script manually using the sievec command line tool, as explained below. But what I would need is execute a global sieve_before for all users to apply some spam selection rules. Did anybody easily achieved it? An obvious workaround would be to create a script which goes through all current users mail directories and creates a sieve_before script with the settings I need and then modify the user creation to do the same when new mailboxes get created. Thank you!

per user procmail filtering and dovecot-lda
by James Nord 18 May '17

18 May '17

Hi all, I recently migrated my system (postfix/Dovecot)from mbox to Maildir. Almost everything is working (phone and thunderbird show all my mail and folders with mail) However I am stuck on my .procmailrc rules # cat /etc/procmailrc SENDMAIL=/usr/sbin/sendmail SENDMAILFLAGS=-oi LOGFILE=/var/log/procmail.log ORGMAIL=${HOME}/Maildir/ DEFAULT=${ORGMAIL} MAILDIR=${HOME}/Maildir/ DELIVER="/usr/lib/dovecot/deliver -d $LOGNAME" # next line is to support user .procmailrc files INCLUDERC=$HOME/.procmailrc :0 w | $DELIVER # cat ~/.procmailrc :0 w * ^List-ID:.*jenkinsci-dev.googlegroups.com | $DELIVER -m mailing-lists/jenkinsci-dev :0 w * ^List-ID:.*jenkinsci-users.googlegroups.com | $DELIVER -m mailing-lists/jenkinsci-users However dovecot-lda complains that the mailboxes "mailing-lists/jenkinsci-users", "mailing-lists/jenkinsci-dev" etc do not exist so delivers to the INBOX. Everything I have read says that the mailbox specified by -m is the name as seen by the mail client, and this is what the client sees (see image). I have tried changing the mailbox to INBOX/mailing-lists/... inbox/mailing-lists/... but the same still happens. So I am missing something somewhere and my google foo is unfortunately letting me down this time. Is there someone that can help me? (I'm not subscribed to the list so a CC to me would be appreciated) Regards /James

You should do doveconf -a | grep sieve_global_path since "-n" won't list unchanged (defaulted) configuration values. Joseph Tam <jtam.home(a)gmail.com>

Conditionally Filter Mails During IMAP Fetch
by Ory Drilon 17 May '17

17 May '17

Hi, is there a way to arbitrarily filter out mails at the moment the IMAP request is made, based on properties of the IMAP session and the mail itself? All the filtering methods I find occur during delivery time.

Re: ACL and virtual user
by Davide Marchi 15 May '17

15 May '17

...I had under my eyes the solution I have not seen: * user=foo lrw Public user=bar lrwstipekxa Public/* user=bar lrwstipekxa I was enough (in my case) add the initial "*" wildcards, like this: * user=info(a)mydomain.com lrwsi where the "*" wildcards means all groups. I have verified and so the configuration is perfect, the user can not delete their own messages The fact remains that on the wiki dovecot ACL these steps, in the case of virtual users, are not clear, at least in my opinion. :-) I hope at least that my experience can be of assistance to other users. Many many thanks! Davide

ACL and virtual user
by Davide Marchi 15 May '17

15 May '17

Hi friends, I would like to remove write rights for a specific virtual user/email address. I've read the wiki "https://wiki2.dovecot.org/ACL" but there is nothing about it. So I started reading and rereading some old ML, like this: https://www.dovecot.org/list/dovecot/2006-June/013683.html where they talk about something like that but I would like to implement current guidelines for the "Global ACL file" and for virtual user. So I've try: * user=foo lrw Public user=bar lrwstipekxa Public/* user=bar lrwstipekxa But in my case for virtual user, so I tried (obviously I changed the email address with a generic one): -------------- #user=info(a)mydomain.com lrwsi -------------- Log: May 15 10:40:44 server dovecot: imap(info(a)mydomain.com): Error: Global ACL file /etc/dovecot/dovecot-acl line 1: Unknown ID 'lrwsi' -------------- #owner #user=info at mydomain.com lrwsi -------------- Log: May 15 10:47:58 server dovecot: imap(info(a)mydomain.com): Error: Global ACL file /etc/dovecot/dovecot-acl line 1: Missing ACL rights -------------- #user=info at mydomain.com lrwsi -------------- Log: May 15 10:51:57 server dovecot: imap(info(a)mydomain.com): Error: Global ACL file /etc/dovecot/dovecot-acl line 2: Unknown ID 'at' But none of these gave results, could you explain better or gime me an example? Many many thanks! Davide Italy

[BUG] doveadm kick doesn't play well with hibernate
by Christian Balzer 15 May '17

15 May '17

Hello, Dovecot 2.2.27 (Debian Jessie backports). When issuing a "doveadm kick" for a specific user I was greeted by: --- "warning: other connections would also be kicked from following users:" --- and a list of 22odd thousand users. As it turns out, kick wants to smack the hibernation proces(ses) that have hibernated sessions for this user, obviously the wrong approach here. If there's doveadm command to wake up and thus un-hibernate sessions for a specific user this could be used as a workaround but a quick glance suggest no such thing. This functionality is absolutely crucial for us as we need this for our custom mailbox migration functionality. If there's no workaround or fix within 2 months I'll be forced to disable hibernation again (with a heavy heart).

Dovecot 2.2.29.1 + VPopMail 5.4.33
by Nicholas Chua 12 May '17

12 May '17

Hi all, I have a fresh installation of a Vpopmail 5.4.33 + Dovecot 2.2.29.1 + SQL As usual I followed the AuthDatabase/VPopMail wiki password_query = SELECT CONCAT(pw_name, '@', pw_domain) AS user, \ pw_clear_passwd AS password \ FROM vpopmail \ WHERE pw_name = '%n' AND pw_domain = '%d' user_query = SELECT pw_dir as home, \ 89 AS uid, 89 AS gid \ FROM vpopmail \ WHERE pw_name = '%n' AND pw_domain = '%d' For VPopMail, I prefer to have an individual table in the vpopmail database for each domain. So my structure will be something like this vpopmail.abc_com vpopmail.xyz_com To achieve this I add this configure when compiling VPopMail --disable-many-domains But dovecot will not read vpopmail.abc_com, instead it keep looking for vpopmail.vpopmail auth-worker(8643): Warning: mysql: Query failed, retrying: Table 'vpopmail.vpopmail' doesn't exist If I remove --disable-many-domains in the configuration, I have no issue. Is there a new password and user query to have this working? The last working version I had installed is Dovecot 2.2.15 Thank you nic

folders in public namespace only visable to 2nd folder level in 2.2.29.1
by Andreas Oster 11 May '17

11 May '17

Hi all, I am currently facing an issue with Dovevot version 2.2.29.1 where subfolders in a public namespace are only visible to the 2nd folder level: namespace Public -> folder "1st" -> folder -> "2nd" -> folder "3rd" .... When one user creates a subfolder below the 2nd level other users do not see that folder and are unable to subscribe to this folder. Folders created under the 1st level however are visible and subscribable by other users. namespace { disabled = no hidden = no ignore_on_failure = no inbox = no list = children type = public separator = / prefix = Public/ location = maildir:/var/vmail/public:INDEXPVT=~/Maildir/public subscriptions = no } I do not know at which point ( dovecot update ) this issue appeared. Does anyone face the same problem ? Thank you for your kind help best regards Andreas
