Query: SELECT "INBOX" permission denied
by Don Levey 12 Nov '14

12 Nov '14

Yesterday I was forced to migrate servers due to a hardware failure. I have been able to bring up my mail server, and set up Squirrelmail and Dovecot. I am able to access (via Squirrelmail) all users' mail except one - which happens to be my wife's, so it would be really helpful if I could get that working too. I am able to log in, but see the following message in the main pane: ERROR: Could not complete request.

Disabling SSLv3 protocol
by Timo Sirainen 12 Nov '14

12 Nov '14

Since people are now talking about the SSLv3 security hole and how to disable it, here's a thread where you can talk about that. In Dovecot v2.1+ you can disable SSLv3 by setting: ssl_protocols = !SSLv2 !SSLv3 In older versions you'd have to patch the source code. Attached a patch against v2.0. I don't know if there are any clients that would break by disabling SSLv3. I'd expect all the clients to use the system (or otherwise generic) SSL libraries, which would automatically choose the TLS protocol over SSL. So my guess is that unless somebody is using over a 10 year old client there wouldn't be any problems. Maybe some old mobile phones might be using SSL.. If you find out about any clients that require SSLv3 I'd like to know about it. For Dovecot v2.3 I could maybe disable SSLv3 by default if there's no real need for it. (Also: Don't be confused by SSL/TLS protocols vs. SSL port/STARTTLS, as described in http://wiki2.dovecot.org/SSL. For example https://en.wikipedia.org/wiki/Comparison_of_email_clients#SSL_and_TLS_suppo… is irrelevant here.)

New director features
by Timo Sirainen 12 Nov '14

12 Nov '14

I implemented a couple of larger director changes today. These could still be changed a bit if somebody has any ideas. http://hg.dovecot.org/dovecot-2.2/rev/b9df3d654710 Support for director "tags", which allow creating multiple Dovecot backend groups using a single director ring. So you can mark different backend hosts with @tag names and then have passdb lookup return the wanted tag for each user. Note that because director works using user hashes, two users with the same hash can't be in different backend groups. Use "doveadm director map -u user@domain" to see which hash is used by the user@domain. http://hg.dovecot.org/dovecot-2.2/rev/b9df3d654710 Added director_consistent_hashing=yes setting so users don't move around much when backend servers are added/removed. Ideally at some point this setting will be removed and directors will automatically switch to it when all the directors in the ring support it.

FTS-Solr: indexer-worker does not find mailbox
by Marc Stürmer 11 Nov '14

11 Nov '14

Greetings, I am running Dovecot v. 2.2.13 on a Gentoo Box. Mail users are virtual, data for them is stored in a MySQL-DB, Sieve is enabled and deliver is the LDA in conjunction with Postfix. This setup has been running for a few years now without problems, the configuration works. Some weeks ago the setup was still on a Ubuntu 12.04 LTS box, and Dovecot was v. 2.0.9. I've installed a Tomcat there with Solr and configured the FTS-Solr plugin from Dovecot. Worked like a charm without any problems at all. Now the same setup on the Gentoo box does not work at all; either indexer-worker does not find the directory or is just indexing 0 messages. Solr is also installed again (v. 3.6.0) on Tomcat, and Solr is running properly. I checked it with my browser and the logs, they are showing no errors. gentoo ~ # dovecot --version 2.2.13 dovecot -n: http://pastebin.com/NqLfrbp8 dovecot-sql.conf: http://pastebin.com/KLf4pjJZ Debug log.

Virtual User Authentication
by Jerry 11 Nov '14

11 Nov '14

I have only "virtual users" on the system that I maintain. I am using Postfix which is configured to use Devecot for authentication. I get several attempts everyday to hack into the system, both via Postfix and directly via Dovecot. The following is from the dovecot log: Nov 11 04:14:48 auth-worker(21005): Error: pam(monica,69.193.88.146): pam_authenticate() failed: authentication error (/etc/pam.d/dovecot missing?) Now, I do not use "pam" on this system. Is there a way I can eliminate Dovecot from trying to use it? -- Jerry

Replication Advice Needed
by Asai 11 Nov '14

11 Nov '14

I successfully set up Dovecot replication, having 2 servers syncing with each other. While I had both servers in the same room on a Gigabit network, they were syncing fine. But I took one to another location, and syncing was turned off for about 2 weeks. Now I've turned both back on, they're sort of syncing, but not really. The one remote server is not populating emails into various folders and it really should be cranking to sync those emails. Do anyone have any insights on how we could troubleshoot this? -- --Asai

deliver an email to a large number of local users directly via doveadm
by Mahdi Mahdi 11 Nov '14

11 Nov '14

Hello,We have a mail service that uses postfix and dovecot. We would like to send an email to a large number of users(about 100K). However, it takes too long to send the email through smtp. Is there any solution to deliver the email locally to all user mailboxes directly.dovecot uses lmtp for transfering local emails. the worst solutoin is that copy the email to all mailboxes via linux file system. But we would prefer to use some tools provided by dovecot like doveadm. is there any way to do this job?

I have a sendmail/dovecot imap/pop3 system that has been running with the following mail_location: mail_location = mbox:/var/empty:INBOX=/var/spool/mail/%u:INDEX=/var/indexes/%u In order to reduce errors and simplify operation I removed imap and am now only responding to pop3. I'd like to also simplify the mail_location to get rid of index errors since I don't need indexes: mail_location = mbox:/var/spool/mail:INBOX=/var/spool/mail/%n But when I applied the new mail_location I began to get the following five errors: Nov 6 23:17:24 sendmail dovecot: pop3(chayes): Warning: UIDVALIDITY changed (1132434125 -> 1205169149) in mbox file /var/spool/mail/chayes Nov 6 23:17:26 sendmail dovecot: pop3(chayes): Panic: Message unexpectedly expunged from index Nov 6 23:17:26 sendmail dovecot: pop3(chayes): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0() [0x3340045e2a] -> /usr/lib64/dovecot/libdovecot.so.0() [0x3340045e6e] -> /usr/lib64/dovecot/libdovecot.so.0(i_fatal+0) [0x3340019eb3] -> /usr/lib64/dovecot/libdovecot-storage.so.0() [0x3ef62567ed] -> /usr/lib64/dovecot/libdovecot-storage.so.0() [0x3ef6256e75] -> /usr/lib64/dovecot/libdovecot-storage.so.0() [0x3ef62928ed] -> /usr/lib64/dovecot/libdovecot-storage.so.0(index_mail_set_seq+0x76) [0x3ef6294ae6] -> /usr/lib64/dovecot/libdovecot-storage.so.0() [0x3ef625698c] -> dovecot/pop3() [0x405ec7] -> dovecot/pop3(client_command_execute+0x6d7) [0x4071c7] -> dovecot/pop3(client_handle_input+0x78) [0x405618] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x36) [0x3340052c36] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0xa7) [0x3340053a57] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x28) [0x3340052778] -> /usr/lib64/dovecot/libdovecot.so.0(master_service_run+0x13) [0x334003e3c3] -> dovecot/pop3(main+0x283) [0x403cc3] -> /lib64/libc.so.6(__libc_start_main+0xf5) [0x359f821a05] -> dovecot/pop3() [0x403e2d] Nov 6 23:17:26 sendmail dovecot: pop3(chayes): Fatal: master: service(pop3): child 3358 killed with signal 6 (core dumps disabled) Nov 6 23:18:00 sendmail dovecot: pop3(jbkirk): Error: open(/var/spool/mail/.imap/INBOX/dovecot.index.log) failed: Permission denied (euid=2151(jbkirk) egid=12(mail) missing +r perm: /var/spool/mail/.imap/INBOX/dovecot.index.log, dir owned by 3575:12 mode=0770) dovecot -n output # 2.1.16: /etc/dovecot/dovecot.conf # OS: Linux 3.9.2-200.fc18.x86_64 x86_64 Fedora release 18 (Spherical Cow) ext4 auth_mechanisms = plain login auth_verbose = yes auth_verbose_passwords = plain disable_plaintext_auth = no mail_location = mbox:/var/empty:INBOX=/var/spool/mail/%u:INDEX=/var/indexes/%u mbox_write_locks = fcntl namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } protocols = pop3 ssl = no ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } What do I need to do to transition to the new mail_location without the errors? Thanks in advance.

Performance issue
by absolutely_free＠libero.it 10 Nov '14

Hi, Since few days I noticed very high load on my mailserver (Centos 6.6 64bit, 8 GB RAM, 2 x CPU 3.00GHz I am using Dovecot + Postfix + Roundcube + Nginx. I have about 10000 users. Spool is on network attached storage (Coraid). File system is ext4 (mounted with noatime). Problem appears almost every morning (while load is normal during afternoon). I suspect that this can be related to some user that have so many messages in his mailbox. How can I troubleshoot this? Here some messages that I got in maillog: Warning: Maildir: Scanning /var/spool/pop/domains/xxxx.it/YYYYYYYYY/Maildir/new took 71 seconds (1 readdir()s, 1 rename()s to cur/) Warning: Maildir /var/spool/pop/domains/zzzz/WWWWWWWWWWWW/Maildir/.Trash: Synchronization took 74 seconds (5 new msgs, 0 flag change attempts, 0 expunge attempts) dovecot: imap(xxxx(a)zzzz.it): Warning: Inotify instance limit for user 89 (UID postfix) exceeded, disabling. Increase /proc/sys/fs/inotify/max_user_instances tail: inotify cannot be used, reverting to polling: Too many open files My relevant dovecot conf: mail_location = maildir:/coraid-s2l2/domains namespace { type = private separator = . prefix = INBOX. inbox = yes } mail_uid = 89 mail_gid = 89 mail_fsync = never first_valid_uid = 89 first_valid_gid = 89 maildir_very_dirty_syncs = yes mbox_write_locks = fcntl thank you very much!

Best practise for deleting with Thunderbird
by Stefan G. Weichinger 09 Nov '14

09 Nov '14

As I mentioned in another thread I set up these 2 namespaces for a couple of users: namespace { inbox = yes location = prefix = separator = / type = private } namespace { location = maildir:/home/vmail/oeffentlich:INDEXPVT=/home/vmail/public/index/%d/%u/index prefix = Oeffentlich/ separator = / subscriptions = yes type = public } It is planned that they all will use Thunderbird (on MS Windows) to access their mailboxes. Now when I create a folder in the public space and try to delete it via thunderbird I get something like: "Renaming not supported across non-private namespaces" As far as I found out by browsing the web this is related to Thunderbird trying to move (=rename) the mail from the public to the private namespace, correct? Setting TB to immediately remove mails (tested that, this works) seems a bit scary to me: this removes a safety layer for the users because this would also apply to their personal maildirs. Is there any more elegant way of solving this? Do I have to set up some kind of ACLs? Some kind of "public paperbin folder" ?? Pls help me to understand this better ;-) Regards, Stefan

Improvement proposal
by Jorge Bastos 09 Nov '14

09 Nov '14

Hi, I'd like to purpose a small improvement. When a user has a quota set in message limit instead of bytes, the returning message it's the same as in bytes limit quota (Quota exceeded (mailbox for user is full)) If possible, when the user has the message limit, it could return something different like: Quota exceeded (max messages reached for user) Thanks, Jorge,

Dovecot quota via custom column
by Filip Bartmann 08 Nov '14

08 Nov '14

Hello, we have multiple domains connected to single user account and we want to have quota counted via this column - called account_id. Users are stored in mysql database. --------------------------------------------------------------------------------- iterate_query = SELECT email AS user FROM mailboxes user_query=SELECT email, 501 AS uid, 501 AS gid, CONCAT('*:storage=',quota,'M') AS quota_rule FROM mailboxes AS m WHERE email='%u' password_query=SELECT email AS user, pw_hash AS password, CONCAT('*:storage=',quota,'M') AS userdb_quota_rule FROM mailboxes AS e WHERE email='%u' --------------------------------------------------------------------------------- We have quota stored in dovecot dictionary and as usable variables we found only - http://wiki2.dovecot.org/Variables. Is there any way to do use account_id as quota username? Thanks, Filip Bartmann

Hi, Ok managed to solve this with the permissions on the socket.
