Sieve removeflag Action
by Thomas Leuxner 26 Feb '17

26 Feb '17

Hi, I recently noticed that some of my automatically processed mails do no longer show flags with current Dovecot builds. This used to work before, not sure what broke it or whether I used it in the wrong way. When the removeflag line is dropped *both* messages get flagged in the client, one in INBOX and one in Trash. With removeflag in place, *both* messages are unflagged, the one in INBOX and the one in Trash. This used to work differently before if memory doesn't fail me. #Test if address :is "From" "user(a)example.com" { addflag "\\Flagged $MailFlagBit1"; keep; removeflag "\\Flagged $MailFlagBit1"; fileinto "Trash"; } # 2.2.devel (01867a4): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.devel (3c071a4) # OS: Linux 3.16.0-4-amd64 x86_64 Debian 8.6 Regards Thomas

Sieve Script Replication Gliches (Report #2)
by Reuben Farrelly 26 Feb '17

26 Feb '17

Hi, I've observed some odd behaviour with dsync replication between two hosts, specifically to do with sieve script replication. In short, I have two hosts which replicate in a master-master type setup where almost all of the reads and writes happen to just one of the two hosts. They are both running 2.2.devel (9dc6403), which is close to the latest 2.2 -git . Pigeonhole is running master-0.4 . This is on x86_64 Gentoo. Normal mail replication between Maildir's for all users works fine, however it appears that something recently committed to the code has broken sieve script replication between the two. I am sure this did once work. Replication is via tcps: . Sieve scripts on the lesser-used host are not up to date by an order of days/weeks with the main host and they don't seem to re-replicate - even if the rules don't exist at all on the replica. The symptoms and effects look to be the same as this (unanswered) post from December: http://dovecot.org/list/dovecot/2015-December/102690.html I am not sure how to view the transaction log files, but I am seeing the same symptoms, ie no live replication, and on the lesser-used host almost all the scripts were old and some had the 1970 date on them. Even after forcing a [dsync replication replicate '*'] the scripts are not replicated. As it stands now there are no sieve scripts on one of the two members and the system seems unable to replicate by itself. Secondly, I am also seeing some doubled up outputs if I run 'doveadm sieve list -A': thunderstorm reuben # doveadm sieve list -A reuben rules ACTIVE liam rules ACTIVE kaylene rules ACTIVE reuben rules ACTIVE liam rules ACTIVE kaylene rules ACTIVE ... Has anyone else experienced the replication problem? Are sieve scripts actually replicating in live time for other 2.2.24/2.2.25 users as well? For me I didn't notice this till I went looking so I wonder if other people are experiencing this but just not aware of it yet...? Reuben

Replication sieve scripts.

26 Feb '17

Hello, Following up on old thread: http://www.dovecot.org/pipermail/dovecot/2014-December/099003.html I have the exact same issue with 2.2.10: 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 As even his version should already support sieve replication through dsync mine would have to support it for sure but I would like to hear a confirmation from the developers. The mail sync just works perfectly between the 2 nodes, it is only the sieve scripts which don't get replicated. I have tried to add additional sieve related options to the replicator: service replicator { process_min_avail = 1 } plugin { mail_replica = tcp:1.2.3.4 replication_full_sync_interval = 1 hours #Added (makes no difference) sieve = ~/.dovecot.sieve sieve_dir = ~/sieve_after sieve_extensions = +vnd.dovecot.duplicate sieve_duplicate_period = 1h #Added (makes no difference) } service aggregator { fifo_listener replication-notify-fifo { user = vmail } unix_listener replication-notify { user = vmail } } It did not help. If there is one way I would like to get this work without upgrading dovecot. Thank you.

sieve file backend: invalid option `active=~/.dovecot.sieve'

Hi, I am seeing the followin error in my logs (doveconf -n at the bottom of this mail): Feb 13 16:59:59 mxf dovecot: lmtp(45560, bp(a)example.com) Error: cs3NOQ7moVj4sQXXXXX: sieve: sieve file backend: invalid option `active=~/.dovecot.sieve' Feb 13 16:59:59 mxf dovecot: lmtp(45560, bp(a)example.com) Error: cs3NOQ7moVj4sQXXXXX: sieve: failed to access user's Sieve script file:~/sieve;active=~/.dovecot.sieve (temporary failure) Looking at http://wiki2.dovecot.org/Pigeonhole/Sieve/Configuration, the syntax "sieve = file:~/sieve;active=~/.dovecot.sieve" in my config is correct ? Is this a false error that is only appearing because this is a newly created user with no sieve file ? If this is the case, how do I tell dovecot not to error out and allow the mail ?

Users with multiple password
by Eirik Rye 24 Feb '17

24 Feb '17

Hi! ~ dovecot --version 2.2.22 (fe789d2) I am wondering if there is a way to set up virtual users with multiple valid passwords. We want to be able to provide users with device/app-specific passwords for their email accounts, as well as being able to create temporary "access tokens" for technical support when required. I quickly found out that passdb using passwd-file or an sql-backend does not support returning multiple entries ("Error: passwd-file /etc/dovecot/virtual.passwd: User rye exists more than once"). The documentation mentions that you can pass the plain-text password on to the MySQL-server for verification, and I suppose multiple passwords could could work, given a query like this (pseudo-SQL): `SELECT password FROM account WHERE user = '%u' AND domain = '%d' AND password = TO_BASE64((SHA2('%w', 512));` However, having Dovecot pass the plain-text password and letting the database deal with the hashing and encoding doesn't seem like a very "clean" solution. Preferably, dovecot should be the only piece of software touching the plain-text. Ideally, I would like the following behavior: 1. passdb results multiple possible hashed passwords for the user 2. dovecot attempts the passwords in order 3. login fails normally if none of the passdb results match Does anyone have any experience, or tips for setting up this type of behavior? Other ideas we have touched upon are: 1. Different usernames (eg. 'user_device' or 'user_application') 2. Multiple passdbs(?) Best regards, Eirik Rye

Hi, On 2.2.10, running the following doveadm -v -o mail_fsync=never backup -R -u my(a)example.com imapc: There is zero output ? Running -D instead of -v it spews out debug messages. Any ideas ? Ben
