Hi all :) I will try to use /usr/lib/dovecot/deliver instead of postfix. I'd like automatically move email to junk folder. I use debian 9. cat /etc/postfix/master.cf [...] spamassassin unix - n n - - pipe user=debian-spamd argv=/usr/bin/spamc -f -e /usr/lib/dovecot/deliver -f ${sender} -d ${recipient} with this line dovecot works perfectly but only with virtual users, my system has also system users /etc/passwd How to tell dovecot to deliver email also to real system users?

Improve dovecot logging
by Slobodan Zdravkovic 06 Sep '17

06 Sep '17

In case when user login with pop3 and only download only mail headers (partial download), but not email body, there is nothing in mail.log Is it possible to configure one of the existing dovecot plugins to log actions like TOP and LIST or is it possible to write new plugin for dovecot which can fetch this actions ?

pam authentication
by Pol Hallen 05 Sep '17

05 Sep '17

Hello all I use debian 9 with dovecot 2.x: real system users and virtual users: almost all works perfectly ;) Virtual users can connect via imap and pop using name + domain name: user00(a)domain1.org, etc. pam (real system users) users can connect via imap and pop ONLY without domain name It's a problem with pam authentication because linux make users authentication with only username (and not with also domain name) but I'd like user full email like test00(a)realdomain.org cat /etc/dovecot/conf.d/auth-passwdfile.conf.ext passdb { driver = passwd-file args = scheme=SHA256 username_format=%u /etc/dovecot/users } userdb { driver = passwd-file args = scheme=SHA256 username_format=%u /etc/dovecot/users } cat /etc/dovecot/conf.d/auth-system.conf.ext passdb { driver = pam } userdb { driver = passwd } inside /etc/dovecot/conf.d/10-auth.conf [...] #auth_username_format = %n is commented because I've multiple domains cat /var/log/dovecot.debug Sep 05 01:49:51 auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.dat Sep 05 01:49:51 auth: Debug: passwd-file /etc/dovecot/users: Read 4 users in 0 secs Sep 05 01:49:51 auth: Debug: auth client connected (pid=23412) Sep 05 01:49:51 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=hjdhgfghhg lip=192.168.1.100 rip=192.168.1.100 lport=143 rport=39356 resp=hsdfhsfddfjk jklsdfkljkdlskfljsdkjlfds== (previous base64 data may contain sensitive data) Sep 05 01:49:51 auth-worker(23414): Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Sep 05 01:49:51 auth-worker(23414): Debug: passwd-file /etc/dovecot/users: Read 4 users in 0 secs Sep 05 01:49:51 auth-worker(23414): Debug: pam(test(a)realdomain.org,192.168.1.100,<PitAxGVYvJnAqAFk>): lookup service=dovecot Sep 05 01:49:51 auth-worker(23414): Debug: pam(test(a)realdomain.org,192.168.1.100,<PitAxGVYvJnAqAFk>): #1/1 style=1 msg=Password: Sep 05 01:49:53 auth: Debug: passwd-file(test(a)realdomain.org,192.168.1.100,<PitAxGVYvJnAqAFk>): lookup: user=test(a)realdomain.org file=/etc/dovecot/users Sep 05 01:49:55 auth: Debug: client passdb out: FAIL 1 user=test(a)realdomain.com Sep 05 01:51:15 auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Sep 05 01:51:15 auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.dat Sep 05 01:51:15 auth: Debug: passwd-file /etc/dovecot/users: Read 4 users in 0 secs Sep 05 01:51:15 auth: Debug: auth client connected (pid=23461) Sep 05 01:51:26 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=ycnxyWVYQYokInmi lip=192.168.0.2 rip=36.34.121.162 lport=993 rport=35393 Sep 05 0 any idea? thanks for help!

AW: problem with shared folders and acls - only able to share INBOX

Hi, i found the solution for my problem (RTFM) doveadm acl debug => Folder \.Subfolder cannot be accessed => dots in maildir format I added a 'Layout=fs' to the namespace definition. Thanks and cheers Christian -----Ursprüngliche Nachricht----- Von: Christian Eisert [mailto:christian.eisert@gmx.net] Gesendet: Freitag, 1.

The ACLs seem to be set right. I have the suspicion that the dictionary ( /var/lib/dovecot/db/shared-mailboxes.db ) is not updated - there are no entries for the sub folders I just cannot find the problem within my configuration.

questions concerning dovecot
by Rajesh M 04 Sep '17

04 Sep '17

hello all had some basic questions 1) what is the logic behind the numbering of files in the conf.d folder ... is this to define the sequence of execution of the config files ? 2) Concerning global scripts, is the default.sieve, before i understand that they get executed when the user does not have his private sieve script. are sieve_before, sieve_after and sieve_global_path all globalscripts ? thanks rajesh

Failed to repair mdbox index / wrong dbox version
by Peer Heinlein 04 Sep '17

After a filesystem crash dovecot isn't able to repair some of the m-Files. That's okay in general -- but I wonder why he's complaining about "wrong dsync version" if I execute "doveadm force-resync" locally: doveadm(user(a)mailbox.org): Warning: mdbox /mail-mailbox/mailbox.org/1846405//mdbox/storage: rebuilding indexes doveadm(user(a)mailbox.org): Error: Corrupted dbox file /xxxx//mdbox/storage/m.340 (around offset=154): Invalid dbox version I would accept every log that it's too broken to be repaired, but "Invalid dbox version"?

v2.2.32 released
by Timo Sirainen 04 Sep '17

04 Sep '17

https://dovecot.org/releases/2.2/dovecot-2.2.32.tar.gz https://dovecot.org/releases/2.2/dovecot-2.2.32.tar.gz.sig Two more fixes since rc2. And repeating: There are various changes in this release that can be used to significantly reduce disk IO with: 1) NFS storage especially, but I guess also other remote filesystems and even some with local disks 2) When mail storage and INDEX storage are separated * imapc: Info-level line is logged every time when successfully connected to the remote server. This includes local/remote IP/port, which can be useful for matching against external logs. * config: Log a warning if plugin { key=no } is used explicitly. v2.3 will support "no" properly in plugin settings, but for now any value at all for a boolean plugin setting is treated as "yes", even if it's written as explicit "no". This change will now warn that it most likely won't work as intended. + Various optimizations to avoid accessing files/directories when it's not necessary. Especially avoid accessing mail root directories when INDEX directories point to a different filesystem. + mail_location can now include ITERINDEX parameter. This tells Dovecot to perform mailbox listing from the INDEX path instead of from the mail root path. It's mainly useful when the INDEX storage is on a faster storage. + mail_location can now include VOLATILEDIR=<path> parameter. This is used for creating lock files and in future potentially other files that don't need to exist permanently. The path could point to tmpfs for example. This is especially useful to avoid creating lock files to NFS or other remote filesystems. For example: mail_location=sdbox:~/sdbox:VOLATILEDIR=/tmp/volatile/%2.256Nu/%u + mail_location's LISTINDEX=<path> can now contain a full path. This allows storing mailbox list index to a different storage than the rest of the indexes, for example to tmpfs. + mail_location can now include NO-NOSELECT parameter. This automatically deletes any \NoSelect mailboxes that have no children. These mailboxes are sometimes confusing to users. + mail_location can now include BROKENCHAR=<char> parameter. This can be useful with imapc to access mailbox names that aren't valid mUTF-7 charset from remote servers. + If mailbox_list_index_very_dirty_syncs=yes, the list index is no longer refreshed against filesystem when listing mailboxes. This allows the mailbox listing to be done entirely by only reading the mailbox list index. + Added mailbox_list_index_include_inbox setting to control whether INBOX's STATUS information should be cached in the mailbox list index. The default is "no", but it may be useful to change it to "yes", especially if LISTINDEX points to tmpfs. + userdb can return chdir=<path>, which override mail_home for the chdir location. This can be useful to avoid accessing home directory on login. + userdb can return postlogin=<socket> to specify per-user imap/pop3 postlogin socket path. + cassandra: Add support for result paging by adding page_size=<n> parameter to the connect setting. + dsync/imapc, pop3-migration plugin: Strip also trailing tabs from headers when matching mails. This helps with migrations from Zimbra. + imap_logout_format supports now %{appended} and %{autoexpunged} + virtual plugin: Optimize IDLE to use mailbox list index for finding out when something has changed. + Added apparmor plugin. See https://wiki2.dovecot.org/Plugins/Apparmor - virtual plugin: A lot of fixes. In many cases it was also working very inefficiently or even incorrectly. - imap: NOTIFY parameter parsing was incorrectly "fixed" in v2.2.31. It was actually (mostly) working in previous versions, but broken in v2.2.31. - Modseq tracking didn't always work correctly. This could have caused imap unhibernation to fail or IMAP QRESYNC/CONDSTORE extensions to not work perfectly. - mdbox: "Inconsistency in map index" wasn't fixed automatically - dict-ldap: %variable values used in the LDAP filter weren't escaped. - quota=count: quota_warning = -storage=.. was never executed (try #2). v2.2.31 fixed it for -messages, but not for -storage. - imapc: >= 32 kB mail bodies were supposed to be cached for subsequent FETCHes, but weren't. - quota-status service didn't support recipient_delimiter - acl: Don't access dovecot-acl-list files with acl_globals_only=yes - mail_location: If INDEX dir is set, mailbox deletion deletes its childrens' indexes. For example if "box" is deleted, "box/child" index directory was deleted as well (but mails were preserved). - director: v2.2.31 caused rapid reconnection loops to directors that were down.
