autoexpunged in IMAP logout format
by Alessio Cecchi 14 Nov '18

14 Nov '18

Hi, in my imap_logout_format I register %{deleted} %{expunged} %{trashed} but now I saw that is available also %{autoexpunged}. Is necessary to add also %{autoexpunged} in logout format to have the count of all deleted email via IMAP? Thanks -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice

Trying to do antispam with Sieve

Hi, Using https://wiki.dovecot.org/HowTo/AntispamWithSieve I'm trying to execute scripts when moving to/from Spam folder, however nothing's happening. The actions are: 1.

execute sieve command - fails to notice script has exited
by Lionel Elie Mamane 13 Nov '18

13 Nov '18

Hi, Running dovecot 2.2.27 (c0f36b0) on Debian GNU/Linux stable (version 9.6), I'm trying to use the execute command in a sieve script, with direct execution (not service socket). The script is executed, and returns (the process exits), but the dovecot-lda process seems to not notice, and thinks the script did not terminate. After sieve_execute_exec_timeout has passed, it sends a TERM, a bit later a KILL and then logs a failure. The "ps -Af f" looks like: S 0:00 \_ /usr/sbin/exim4 -Mc 1gMazS-0007IV-RB S 0:00 \_ /usr/lib/dovecot/dovecot-lda -f master(a)blitz.conuropsis.org Z 0:00 | \_ [foofilter] <defunct> S 0:00 \_ /usr/sbin/exim4 -Mc 1gMazS-0007IV-RB The dovecot debug log looks like: lda(user): Debug: Loading modules from directory: /usr/lib/dovecot/modules lda(user): Debug: Module loaded: /usr/lib/dovecot/modules/lib90_sieve_plugin.so lda(user): Debug: Effective uid=1000, gid=1000, home=/home/user lda(user): Debug: maildir++: root=/home/user/Maildir, index=, indexpvt=, control=, inbox=/home/user/Maildir, alt= lda(user): Debug: userdb lookup skipped, username taken from USER environment lda(user): Debug: none: root=, index=, indexpvt=, control=, inbox=, alt= lda(user): Debug: Destination address: user(a)blitz.conuropsis.org (source: user@hostname) lda(user): Debug: sieve: Pigeonhole version 0.4.16 (fed8554) initializing lda(user): Debug: sieve: include: sieve_global is not set; it is currently not possible to include `:global' scripts. lda(user): Debug: sieve: Sieve imapsieve plugin for Pigeonhole version 0.4.16 (fed8554) loaded lda(user): Debug: sieve: Sieve Extprograms plugin for Pigeonhole version 0.4.16 (fed8554) loaded lda(user): Debug: sieve: file storage: Using active Sieve script path: /data/home/user/.dovecot.sieve lda(user): Debug: sieve: file storage: Using script storage path: /home/user/sieve lda(user): Debug: sieve: file storage: Relative path to sieve storage in active link: sieve/ lda(user): Debug: sieve: file storage: Using Sieve script path: /data/home/user/.dovecot.sieve lda(user): Debug: sieve: file script: Opened script `test-foofilter' from `/data/home/user/.dovecot.sieve' lda(user): Debug: sieve: Using the following location for user's Sieve script: /data/home/user/.dovecot.sieve lda(user): Debug: Mailbox stdin: Opened mail UID=1 because: header Message-ID (Cache file is unusable) lda(user): Debug: sieve: Opening script 1 of 1 from `/data/home/user/.dovecot.sieve' lda(user): Debug: sieve: Loading script /data/home/user/.dovecot.sieve lda(user): Debug: sieve: Script binary /data/home/user/.dovecot.svbin successfully loaded lda(user): Debug: sieve: binary save: not saving binary /data/home/user/.dovecot.svbin, because it is already stored lda(user): Debug: sieve: Executing script from `/data/home/user/.dovecot.svbin' lda(user): Debug: sieve: action execute: running program: foofilter lda(user): Debug: Mailbox stdin: Opened mail UID=1 because: mail stream lda(user): Debug: waiting for program `/usr/local/lib/dovecot/sieve-execute/foofilter' to finish after 0 msecs lda(user): Debug: program `/usr/local/lib/dovecot/sieve-execute/foofilter'(24669) execution timed out after 2000 milliseconds: sending TERM signal lda(user): Debug: program `/usr/local/lib/dovecot/sieve-execute/foofilter' (24669) did not die after 5000 milliseconds: sending KILL signal and an strace on the dovecot-lda process shows it is in an "epoll_wait(9 ....". The script is very simple: #! /bin/sh cat > /dev/null exit 1 Anyone has a clue? Thanks in advance. Best Regards, Lionel

Proxy + 2x static passdb not working as expected
by Michael Goth 13 Nov '18

13 Nov '18

Hi all, I'm trying to setup a Dovecot proxy that authenticates the user against two backend servers. If login server1 fails, server2 should be tried. The problem: Only the first server seems to be tried, even if the login fails. Config snippet: protocol imap { passdb { driver = static args = proxy=y nopassword=y host=oldserver1.example.com port=993 ssl=y } passdb { driver = static args = proxy=y nopassword=y host=oldserver2.example.com port=993 ssl=y } } With this config, only accounts on oldserver1.example.com can login. If I reverse the two passdb entries, only accounts on oldserver2.example.com can login. I've done the same with SQL passdb first + static passdb second. That worked as expected. Not sure what I'm doing wrong here. Attached is the output of doveconf -n Thanks Michael Mit freundlichen Grüßen -- Michael Goth .webflow GmbH Geschäftsführer: Andreas Schrei Wasserburger Straße 4 D - 83352 Altenmarkt a. d.

dsync / doveadm sync problem
by admin＠awib.it 13 Nov '18

13 Nov '18

Hi, I had an old dovecot server with a working backup script. Basic concept was: - to dsync to a temp folder - using tar to preserve datetime - piping this 7z to benefit from my 16 core cpu - piping this through openssl to encrypt Over time the size of all my mail grew from 3GB to about 70GB. I used to keep the last 14 backups, but this uses a lot of space. I now want to dsync my Maildir onto my NAS via NFS and use the backup tool provided by Synology to have incremental compressed backup. However I cannot get dsync to run. root@mail:/mnt/backup_mail# dsync -f -u USER@DOMAIN backup maildir:/mnt/backup_mail/MAILSERVER_FQDN/DOMAIN/USER/mail dsync(USER@DOMAIN): Error: User initialization failed: Namespace '': stat(/mnt/backup_mail/MAILSERVER_FQDN/DOMAIN/USER/mail) failed: Permission denied (euid=1001(vmail) egid=1001(vmail) missing +x perm: /mnt/backup_mail, UNIX perms appear ok (ACL/MAC wrong?)) root@mail:/mnt/backup_mail# dsync -u USER@DOMAIN backup maildir:/mnt/backup_mail/MAILSERVER_FQDN/DOMAIN/USER/mail dsync(USER@DOMAIN): Error: User initialization failed: Namespace '': stat(/mnt/backup_mail/MAILSERVER_FQDN/DOMAIN/USER/mail) failed: Permission denied (euid=1001(vmail) egid=1001(vmail) missing +x perm: /mnt/backup_mail, dir owner missing perms) ——— Error message changed after removing „-f“. I then applied the folder permissions (chmod +x backup_mail/) and I get a different error: root@mail:/mnt/backup_mail# dsync -f -u USER@DOMAIN backup maildir:/mnt/backup_mail/MAILSERVER_FQDN/DOMAIN/USER/mail dsync(USER@DOMAIN): Error: User initialization failed: namespace configuration error: All list=yes namespaces must use the same separator I found something about the namespace issue, but did not quite understand I guess. (separators seem to differ) From doveconf -n: [...] namespace { list = children location = maildir:/var/vmail/mailboxes/%%d/%%n/Maildir:INDEXPVT=~/Maildir/shared/%%u prefix = shared/%%u/ separator = / subscriptions = yes type = shared } namespace inbox { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Spam { auto = subscribe autoexpunge = 30 days special_use = \Junk } mailbox Trash { auto = subscribe autoexpunge = 183 days special_use = \Trash } prefix = } […] ——— However I only set up the namespace for inbox. root@mail:/mnt/backup_mail# doveconf namespace gives namespace { disabled = no hidden = no ignore_on_failure = no inbox = no list = children location = maildir:/var/vmail/mailboxes/%%d/%%n/Maildir:INDEXPVT=~/Maildir/shared/%%u order = 0 prefix = shared/%%u/ separator = / subscriptions = yes type = shared } namespace inbox { disabled = no hidden = no ignore_on_failure = no inbox = yes list = yes location = mailbox Drafts { auto = subscribe autoexpunge = 0 autoexpunge_max_mails = 0 comment = driver = special_use = \Drafts } mailbox Sent { auto = subscribe autoexpunge = 0 autoexpunge_max_mails = 0 comment = driver = special_use = \Sent } mailbox Spam { auto = subscribe autoexpunge = 60 days autoexpunge_max_mails = 0 comment = driver = special_use = \Junk } mailbox Trash { auto = subscribe autoexpunge = 60 days autoexpunge_max_mails = 0 comment = driver = special_use = \Trash } order = 0 prefix = separator = subscriptions = yes type = private } I guess here we see the config including defaults. Well… I think I only need the inbox namespace either way, so I tried: root@mail:/mnt/backup_mail# dsync -f -u USER@DOMAIN backup maildir:/mnt/backup_mail/MAILSERVER_FQDN/DOMAIN/USER/mail/ -n inbox dsync-local(USER@DOMAIN): Error: read(remote) failed: EOF (version not received) doveadm(USER@DOMAIN): Fatal: execvp(maildir:/mnt/backup_mail/MAILSERVER_FQDN/DOMAIN/USER/mail/) failed: No such file or directory dsync-local(USER@DOMAIN): Error: Remote command process isn't dying, killing it dsync-local(USER@DOMAIN): Error: kill(15306, SIGKILL) failed: Operation not permitted The folder (mnt/backup_mail/MAILSERVER_FQDN/DOMAIN/USER/mail) however does exist. Can anybody tell me if there is something I miss? Thanks in advance! -M
