dovecot 2.1 new imap folder permissions
by Stefanos Gerangelos 07 Oct '14

07 Oct '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I hope this is the appropriate place to ask. I am migrating an old mail (postfix/dovecot) server to a new one. Everything works much as expected. I have a small obstacle though. I use mbox format and the setup is pretty much simple. Suppose a user's home directory is the following: # ls -ld /home/foo drwxr-xr-x 3 foo users 4096 Oct 4 13:28 foo and the respective /var/mail: # ls -ld /var/mail/foo - -rw------- 1 foo mail 0 Oct 4 23:45 /var/mail/foo In the old server when the user tried to create a new test imap folder (from an imap client), then the newly created file would be: # ls -l /home/foo/ - -rw------- 1 foo users 0 Oct 2 02:08 test This is the desired behavior. In the new dovecot 2.1 server the following file permissions will apply: # ls -l /home/foo/ - -rw-r--r-- 1 foo users 0 Oct 2 02:08 test I finally noticed that if I chmod the /home/foo to 711, then the new file will have the desired (600) permissions. So, I can make a umask for the new users (login.defs), but that doesn't sound a pretty solution. Do you have anything else to suggest? If you need any .conf file, let me know. Thanks in advance! - --Stefanos -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQEcBAEBAgAGBQJUM9k6AAoJEDvFaozEhZub3rwIAKglt/6iAU61rCfWJf6yfMZY HNp3rXz4WDbxhOT+eeuoHNN4QLQFTVmjYoqGpqJEazntdMKJqJ1At3osGtzUMYDe iMuhsbcP+tpMAkeFcYB69cW+HvcmWsPafRJoCgziHapT2VxluWH0rfZIDGmvBI5e kQ31ef9IHZjiBwyKf37e8QraU85HDXgF6AhcJ5I7PlDcJDW/jFGFKOUwDoKJ2BU9 JMUBWDALUZ9Uosd+8P8b11TcjjGdakKBPozvu8aAOKd9jz3G9bvatdHnZkD/OJFl pIrnrQuaBA1bW4UP8nTTSyQVuvLKYpMLbN+NTym8SaEU3BwjirWbRDozHLugXio= =lpy7 -----END PGP SIGNATURE-----

Hi Gianluca, I have roundcubemail as webmail. It has a plugin called 'acl', that allows users create acls easly. My users use to use thunderbird too, and the solution is that add-on: https://addons.mozilla.org/en-US/thunderbird/addon/imap-acl-extension/ On 10/06/2014 09:49 AM, Gianluca Calloni wrote: > Hi dovecot guru.. > > > > I need some help configuring shared folder in my server.. > > This is the situation: > > DOVECOT 2.0.19 > > with POSTFIX - CLAMAV - AMAVISD - SPAMASSASSIN > > > > This is the production server and sharing folder between user work.. > > But i need some explanation.. > > > > 1) It's possible to share only a subfolder (E.G. => .INBOX.ESTERO) without > share the main folder .INBOX? > > 2) Which is the best way (or best practice) to manage the dovecot-acl and > dovecot-acl-list file??

Dovecot writing to mailbox user@domain
by John Oliver 06 Oct '14

06 Oct '14

centOS 6.5, dovecot-2.0.9-7.el6_5.1.x86_64 This is frustrating, because I had it working before... I could deliver an email to a user user@domain, then connect to dovecot IMAP and see the mail, no problem! Then I was told we had to use cyrus, and I was dealing with it for a few weeks. Now we're back to dovecot, and the last backup I had of that config has postfix delivering mail to /var/vmail/username as I want and expect, but dovecot looks for and creates /var/vmail/user@domain which I DON'T want [joliver@test ~]$ dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-431.el6.x86_64 x86_64 CentOS release 6.5 (Final) ext4 auth_username_format = %Lu mail_access_groups = mail mail_location = maildir:/var/vmail/%u/Maildir mail_privileged_group = mail mbox_write_locks = fcntl passdb { driver = pam } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocols = imap ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } userdb { args = uid=504 gid=505 home=/var/vmail/%u driver = static } [joliver@test ~]$ cat /etc/dovecot/dovecot-ldap.conf.ext hosts = localhost auth_bind = no ldap_version = 3 debug_level = 0 default_pass_scheme = SSHA base = ou=Users,dc=test,dc=com scope = subtree pass_filter = (&(objectClass=user)(uid=%u)) pass_attrs = mail=user,userPassword=password -- *********************************************************************** * John Oliver http://www.john-oliver.net/ * * * ***********************************************************************

How best to confirm that dovecot LDA logging is working correctly?
by Ben Johnson 06 Oct '14

06 Oct '14

Hello! I've posted to the list several times about a strange issue I'm having with dovecot LDA. When dovecot-lda is called in the context of a pipe script that is executed as the "vmail" user via the Dovecot Antispam plugin, dovecot-lda exits prematurely with status code 134. The dovecot deliver manual at http://wiki2.dovecot.org/LDA#logging states very clearly, "If dovecot-lda fails to write to log files it exits with temporary failure." That's a curious note, because I believe that a "temporary failure" exit code may be what I'm dealing with here. When I drag an email from Inbox to SPAM to trigger Antispam, I see only this (and no further output beyond the last line) in syslog, which is the configured logging destination for LDA: imap: antispam: mailbox_is_unsure(Junk): 0 imap: antispam: mailbox_is_trash(INBOX): 0 imap: antispam: mailbox_is_trash(Junk): 0 imap: antispam: mail copy: from trash: 0, to trash: 0 imap: antispam: mailbox_is_spam(INBOX): 0 imap: antispam: mailbox_is_spam(Junk): 1 imap: antispam: mailbox_is_unsure(INBOX): 0 imap: antispam: mail copy: src spam: 0, dst spam: 1, src unsure: 0 imap: antispam: running mailtrain backend program /bin/bash imap: antispam: running mailtrain backend program /bin/bash imap: antispam: running mailtrain backend program parameter 1 /usr/local/bin/sa-learn-pipe.sh imap: antispam: running mailtrain backend program parameter 2 --spam By contrast, if I "su" to the "vmail" user and call the LDA executable with the same arguments that my pipe script does, I see all of the expected output in syslog, AND the message is delivered successfully: /usr/lib/dovecot/deliver -d "sa-training(a)localhost.com" -m "Training.SPAM" -p "/tmp/sendmail-msg-25169.txt" lda: Debug: Loading modules from directory: /usr/lib/dovecot/modules lda: Debug: Module loaded: /usr/lib/dovecot/modules/lib10_quota_plugin.so lda: Debug: Module loaded: /usr/lib/dovecot/modules/lib90_sieve_plugin.so lda: Debug: auth input: sa-training(a)localhost.com home=/var/vmail/localhost.com/sa-training mail=maildir:/var/vmail/localhost.com/sa-training/Maildir uid=5000 gid=5000 quota_rule=*:storage=0B sieve=/var/vmail/localhost.com/sa-training/.sieve lda: Debug: Added userdb setting: mail=maildir:/var/vmail/localhost.com/sa-training/Maildir lda: Debug: Added userdb setting: plugin/quota_rule=*:storage=0B lda: Debug: Added userdb setting: plugin/sieve=/var/vmail/localhost.com/sa-training/.sieve lda(sa-training(a)localhost.com): Debug: Effective uid=5000, gid=5000, home=/var/vmail/localhost.com/sa-training lda(sa-training(a)localhost.com): Debug: Quota root: name=user backend=dict args=:file:/var/vmail/localhost.com/sa-training/.quotausage lda(sa-training(a)localhost.com): Debug: Quota rule: root=user mailbox=* bytes=0 messages=0 lda(sa-training(a)localhost.com): Debug: Quota rule: root=user mailbox=Trash bytes=+104857600 messages=0 lda(sa-training(a)localhost.com): Debug: Quota rule: root=user mailbox=Junk ignored lda(sa-training(a)localhost.com): Debug: Quota rule: root=user mailbox=INBOX bytes=+104857600 messages=0 lda(sa-training(a)localhost.com): Debug: Quota warning: bytes=0 (100%) messages=0 reverse=no command=quota-reached 100 sa-training(a)localhost.com localhost.com lda(sa-training(a)localhost.com): Debug: Quota warning: bytes=0 (95%) messages=0 reverse=no command=quota-warning 95 sa-training(a)localhost.com localhost.com lda(sa-training(a)localhost.com): Debug: Quota warning: bytes=0 (80%) messages=0 reverse=no command=quota-warning 80 sa-training(a)localhost.com localhost.com lda(sa-training(a)localhost.com): Debug: Quota warning: bytes=0 (100%) messages=0 reverse=yes command=quota-below below sa-training(a)localhost.com localhost.com lda(sa-training(a)localhost.com): Debug: Quota grace: root=user bytes=0 (10%) lda(sa-training(a)localhost.com): Debug: dict quota: user=sa-training(a)localhost.com, uri=file:/var/vmail/localhost.com/sa-training/.quotausage, noenforcing=0 lda(sa-training(a)localhost.com): Debug: maildir++: root=/var/vmail/localhost.com/sa-training/Maildir, index=, indexpvt=, control=, inbox=/var/vmail/localhost.com/sa-training/Maildir, alt= lda(sa-training(a)localhost.com): Debug: Quota root: name=user backend=dict args=:file:/var/vmail//raw mail user/.quotausage lda(sa-training(a)localhost.com): Debug: Quota warning: bytes=0 (100%) messages=0 reverse=no command=quota-reached 100 raw mail user lda(sa-training(a)localhost.com): Debug: Quota warning: bytes=0 (95%) messages=0 reverse=no command=quota-warning 95 raw mail user lda(sa-training(a)localhost.com): Debug: Quota warning: bytes=0 (80%) messages=0 reverse=no command=quota-warning 80 raw mail user lda(sa-training(a)localhost.com): Debug: Quota warning: bytes=0 (100%) messages=0 reverse=yes command=quota-below below raw mail user lda(sa-training(a)localhost.com): Debug: Quota grace: root=user bytes=0 (10%) lda(sa-training(a)localhost.com): Debug: dict quota: user=raw mail user, uri=file:/var/vmail//raw mail user/.quotausage, noenforcing=0 lda(sa-training(a)localhost.com): Debug: none: root=, index=, indexpvt=, control=, inbox=, alt= lda(sa-training(a)localhost.com): Debug: Destination address: sa-training(a)localhost.com (source: user@hostname) lda(sa-training(a)localhost.com): Debug: sieve: Pigeonhole version 0.4.2 initializing lda(sa-training(a)localhost.com): Debug: sieve: include: sieve_global_dir is not set;

the implication seems to be that dovecot-lda is crashes immediately, before it can log anything, when it's triggered via Antispam. Is there some way to determine what's happening? I've posted coredump and trace information previously, and nobody replied. Thanks for any help! -Ben

Help with shared folder
by Gianluca Calloni 06 Oct '14

Hi dovecot guru.. I need some help configuring shared folder in my server.. This is the situation: DOVECOT 2.0.19 with POSTFIX - CLAMAV - AMAVISD - SPAMASSASSIN This is the production server and sharing folder between user work.. But i need some explanation.. 1) It's possible to share only a subfolder (E.G. => .INBOX.ESTERO) without share the main folder .INBOX? 2) Which is the best way (or best practice) to manage the dovecot-acl and dovecot-acl-list file?? Actually, i modifiy the dovecot-acl by hand (vi editor). but every time i modify it i need to restart the dovecot server to apply the configuration. And i need to reset the /var/run/dovecot/dict owner and group cause with dovecot restart the file go back in root:root owner - group Thank's in advance. Gianluca

v2.2.14.rc1 released
by Timo Sirainen 06 Oct '14

06 Oct '14

http://dovecot.org/releases/2.2/rc/dovecot-2.2.14.rc1.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.14.rc1.tar.gz.sig I've wanted to do this release for months now, but I keep being too busy all the time. This release fixes several important bugs and a lot of smaller ones. Because there are such a large number of changes I thought I'd make this release candidate release first and the final v2.2.14 early next week. I usually read through the Dovecot mailing list mails before making a new release to see if there are some (important) bugs reported, but I've been way too busy recently to read through everything. I still have over 250 unread mails and I don't think I'll have time to read them anytime soon. On the positive side the Dovecot company is now hiring more people. Especially having more Dovecot coders would reduce my work load and maybe allow me to go back to reading the Dovecot mailing list daily.. See: http://www.dovecot.fi/dovecot-is-hiring-software-engineer-helsinki/ (you can do this work anywhere - no need to live in Finland) http://www.dovecot.fi/dovecot-is-hiring-operations-and-support-engineer-hel… (this probably requires living in Finland) http://www.dovecot.fi/dovecot-is-hiring-technical-pre-sales-engineer-helsin… (probably no need to live in Finland) Here are some of the larger changes since v2.2.13: * lmtp: Delivered-To: header no longer contains <> around the email address. Other MDAs don't have it either. * "Out of disk space" errors are now treated as temporary errors (not the same as "Out of disk quota"). * replication plugin: Use replication only for users who have a non-empty mail_replica setting. + lmtp proxy: Log a line about each mail delivery. + Added login_source_ips setting. This can be used to set the source IP address round-robin from a pool of IPs (in case you run out of TCP ports). + Rawlog settings can use tcp:<host>:<port> as the path. + virtual plugin: Don't keep more than virtual_max_open_mailboxes (default 64) number of backend mailboxes open. + SSL/TLS compression can be disabled with ssl_options=no_compression + acl: Global ACL file now supports "quotes" around patterns. + Added last-login plugin to set user's last-login timestamp on login. + LDAP auth: Allow passdb credentials lookup also with auth_bind=yes - IMAP: MODSEQ was sent in FETCH reply even if CONDSTORE/QRESYNC wasn't enabled. This broke at least old Outlooks. - passdb static treated missing password field the same as an empty password field. - mdbox: Fixed potential infinite looping when scanning a broken mdbox file. - imap-login, pop3-login: Fixed potential crashes when client disconnected unexpectedly. - imap proxy: The connection was hanging in some usage patterns. This mainly affected older Outlooks. - lmtp proxy: The proxy sometimes delivered empty mails in error situations or potentially delivered truncated mails. - fts-lucene: If whitespace_chars was set, we may have ended up indexing some garbage words, growing the index size unnecessarily. - -c and -i parameters for dovecot/doveadm commands were ignored if the config socket was readable. - quota: Quota recalculation didn't include INBOX in some setups. - Mail headers were sometimes added to dovecot.index.cache in wrong order. The main problem this caused was with dsync+imapc incremental syncing when the second sync thought the local mailbox had changed. - doveadm backup didn't notice if emails were missing from the middle of the destination mailbox. Now it deletes and resyncs the mailbox.

Hi, I am chasing a problem with sieve vacation messages. the sieve file looks like this: ## Generated by Roundcube Webmail SieveRules Plugin ## require ["copy","vacation"]; # rule:[computerisms.ca] if anyof (address :contains "To" "bob.miller(a)ctfn.ca", address :contains "Cc" "bob.miller(a)ctfn.ca") { redirect :copy "bob(a)computerisms.ca"; vacation :days 66 :subject "autotest" "hello back"; } The mail is forwarded, but no vacation response is sent, and the mail is not forwarded. I find the lda error like this: _discarding_vacation_response_for_implicitly_delivered_message; _no_known_(envelope)_recipient_address_found_in_message_headers_ (recipient=<bob.miller(a)hostname.domain.tld>,_and_no_additional_ `:addresses'_are_specified) I am presuming this is the source of my problem. I am not sure why the domain is being modified to reflect the fqdn of the mail server host. When I look at the delivered mail, I find the following two headers: X-sieve-redirected-from: bob.miller(a)hostname.domain.tld Delivered-to: bob.miller(a)domain.tld I have been looking for a while now, and I can't figure out where it is picking up the hostname from. doveconf -a | grep hostname comes up empty. the hostname is not in any of the mta config files.

Dovecot does not update maildirsize after expunge
by Király Balázs 04 Oct '14

04 Oct '14

Hello, At the first, sorry for my englishJ I have a problem with dovecot quota since i migrated from courier. Dovecot does not update the Maildirsize after expunge, and the user running out of his quota very quickly. I checked, the file is deleted from the filesystem. If i delete the Maildirsize file, dovecot regenerate it with the correct datas when a new mail arrive. Also tried to set mail_debug=yes, but it doesnt show anything in the log, when delete mails. Im using NFS as homedirs, i tried to turn off the releated options in configuration, but didnt help. Has anyone any idea how to fix this issue? Thank you!
