"subscription" file/folder for IMAP
by Jorge Bastos 19 Nov '14

19 Nov '14

Hi, For IMAP users, there's the subscription file in the user's home, and if I try to subscribe more imap folders that are invisible, there's that one, but as it is an file, nothing is supposed to happen. Is there an way to, allow users to create the "subscriptions" folder without any collision, or just deny or don't show this file as an possible folder (which Is not) to subscribe. What does people normally do? Thanks in advanced,

Storage IOPs Calculation for Qmail Server
by SasiKumar.K 19 Nov '14

19 Nov '14

Dear DovecotORG, In my organization, we are about to implement Qmail Server. * The number of current users will be 800, in future it may increase upto 1200. * The number of concurrent users will be 300. I am the engineer to deploy the Qmail in Linux server. I need to tell the storage team on the IOPs requirement. I requested 8TB usable space for the mail storage (can scale up in future). Kindly provide your suggestion on this. Thanks & Regards, K.SasiKumar Systems Engineer, Locuz Enterprise Solutions Limited, Bangalore

userdb-nss crash
by Yuriy Tabolin 18 Nov '14

18 Nov '14

Hi All. I have a some problem with dovecot, when I try to use nss in auth userdb. nss was setup to resolve users and group by winbind. nss and winbind works well, command "id user" shows remote user's info. I would like to use nss userdb, but dovecot crashes on start. Is this a bug or incorrect settings? Thank you for any help. dovecot log Nov 18 14:58:36 mail dovecot: auth: Panic: file userdb-nss.c: line 110 (userdb_nss_preinit): assertion failed: (bufsize > 0) Nov 18 14:58:36 mail dovecot: auth: Fatal: master: service(auth): child 19387 killed with signal 6 (core dumped) Nov 18 14:58:36 mail dovecot: master: Error: service(auth): command startup failed, throttling for 8 secs # doveconf -n # 2.2.15: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 10.0-RELEASE-p12 amd64 ufs auth_cache_size = 256 M auth_failure_delay = 3 secs auth_username_format = %n auth_verbose = yes auth_winbind_helper_path = /usr/local/bin/ntlm_auth base_dir = /var/run/dovecot/ disable_plaintext_auth = no listen = * mail_location = maildir:/home/%u/Maildir passdb { args = dovecot driver = pam } protocols = imap service anvil { client_limit = 2051 } service auth { client_limit = 3000 } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } process_limit = 1000 process_min_avail = 5 service_count = 1 vsz_limit = 64 M } service imap { process_limit = 2048 vsz_limit = 256 M } ssl = no userdb { args = service=winbind driver = nss } verbose_proctitle = yes protocol imap { mail_max_userip_connections = 20 } # gdb /usr/local/libexec/dovecot/auth /home/tabolin/auth.core GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.

custom ssh port doveadm sync
by dvm＠rdyn.net 18 Nov '14

18 Nov '14

Hi all, First sorry i really couldn't find it back been searching everywhere even the docs and its bit confusing. I am using # doveadm -D sync -u *(a)mydomain.net remote:myserver.net # which works perfect however for security reasons we now need to change the sshd port on the remote server. How do i tell doveadm to use a custom SSH port (would love to continue to use just the ssh connection), if anyone could explain that would be great, because all i found is custom tcp or tcp ssl which is not what we want to use, as i wish to stick with custom ssh port. Regards, r. -- This email was Virus checked by UTM 9. http://www.astaro.org

Different SSL certificates per IP and protocol
by tree 18 Nov '14

18 Nov '14

Hi Dovecot Users and Developers, I am hosting the server with multiple domains. I have setup the dovecot with the instructions from http://wiki2.dovecot.org/SSL/DovecotConfiguration Each domain has it's own ip address. However, when I connect via Thunderbird or any other mail clients, the client is ONLY picking up the top-level "default" ssl_key and ssl_cert and the certificat in /etc/ssl/dovecot.pem Is this a bug? This is on Debian Wheezy. Any help pointing in the right direction would be appreciated thanks. Here is the ssl section: ----------- ssl_cert = </etc/ssl/dovecot.pem ssl_key = </etc/ssl/dovecot.pem local 192.0.2.10 { # instead of IP you can also use hostname, which will be resolved protocol imap { ssl_cert = </etc/ssl/dovecot/imap-01.example.com.cert.pem ssl_key = </etc/ssl/dovecot/imap-01.example.com.key.pem } protocol pop3 { ssl_cert = </etc/ssl/dovecot/pop-01.example.com.cert.pem ssl_key = </etc/ssl/dovecot/pop-01.example.com.key.pem } } local 192.0.2.20 { protocol imap { ssl_cert = </etc/ssl/dovecot/imap-02.example.com.cert.pem ssl_key = </etc/ssl/dovecot/imap-02.example.com.key.pem } protocol pop3 { ssl_cert = </etc/ssl/dovecot/pop-02.example.com.cert.pem ssl_key = </etc/ssl/dovecot/pop-02.example.com.key.pem } } -----------------------

Mail sync at filesystem level
by Cédric Jeanneret 18 Nov '14

18 Nov '14

Hello, I'm currently building a mail infra using some decentralized filesystem for the storage. As I'm wanting to get multiple "entry-points" (servers running dovecot + postfix + other mail-related stuff), all of them sharing the same storage (most probably xtreemfs), how will dovecot cope in this case? As I see things: server1 gets a mail for User1; it pushes it to the xtreemfs directory. server2 shares the same xtreemfs directory, thus it can access the same mail listing User1 connects to server2: will he see the new mail? Will dovecot on server2 know about it? Thanks! Cheers, C.

Understanding why Dovecot unexpectedly died
by Luca Bertoncello 18 Nov '14

18 Nov '14

Hi list! I use Dovecot 1.2.17 (I can't upgrade right now, due to many reasons), controlled by Pacemaker (I have an HA-Cluster). Now I see that Pacemaker restarts often Dovecot. I wrote my own script to manage Dovecot, since Pacemaker does not have his own. My script, by the "monitor" section has this: monitor) if [ ! -e $OCF_RESKEY_pid ]; then echo "stopped (no pidfile)" echo "DOVECOT STOPPED - NO PIDFILE" | /usr/bin/logger -p local0.info -t DOVECOT-MONITOR -i exit $OCF_NOT_RUNNING else /bin/ps axuwf | /bin/grep `/bin/cat $OCF_RESKEY_pid` | /bin/grep -v grep > /dev/null 2>&1 if [ $? -ne 0 ]; then echo "stopped" echo "DOVECOT STOPPED - NO PROCESS" | /usr/bin/logger -p local0.info -t DOVECOT-MONITOR -i exit $OCF_NOT_RUNNING else if [ "`/bin/netstat -tupan | /bin/grep dovecot | /bin/grep $OCF_RESKEY_bindaddr | /usr/bin/wc -l`" -ne 0 ]; then exit $OCF_SUCCESS else echo "DOVECOT STOPPED - NO LISTEN [`/bin/netstat -tupan | /bin/grep dovecot`]" | /usr/bin/logger -p local0.info -t DOVECOT-MONITOR -i exit $OCF_ERR_GENERIC fi fi fi exit $OCF_SUCCESS ;; The "loggers" was added now to try to understand why it dies... Well, I can see in my syslog, when Pacemaker restarts Dovecot, these lines: ov 15 18:59:09 mail01 DOVECOT-MONITOR[530]: DOVECOT STOPPED - NO LISTEN [tcp 0 0 192.168.33.1:37545 192.168.33.3:3306 ESTABLISHED 637/dovecot-auth Nov 15 18:59:09 mail01 DOVECOT-MONITOR[530]: tcp 0 0 192.168.33.1:37537 192.168.33.3:3306 ESTABLISHED 529/dovecot-auth] So, there is no "dovecot"-Process listening anymore... Normally I have these: tcp 0 0 0.0.0.0:110 0.0.0.0:* LISTEN 634/dovecot tcp 0 0 0.0.0.0:143 0.0.0.0:* LISTEN 634/dovecot tcp 0 0 0.0.0.0:993 0.0.0.0:* LISTEN 634/dovecot tcp 0 0 0.0.0.0:995 0.0.0.0:* LISTEN 634/dovecot tcp 0 0 192.168.33.1:40994 192.168.33.3:3306 VERBUNDEN 891/dovecot-auth tcp 0 0 192.168.33.1:40984 192.168.33.3:3306 VERBUNDEN 638/dovecot-auth tcp6 0 0 :::110 :::* LISTEN 634/dovecot tcp6 0 0 :::143 :::* LISTEN 634/dovecot tcp6 0 0 :::993 :::* LISTEN 634/dovecot tcp6 0 0 :::995 :::* LISTEN 634/dovecot In the mail.log and mail.err I can't see anything but: Nov 15 18:59:13 mail01 dovecot: Dovecot v1.2.17 starting up Nov 15 18:59:13 mail01 dovecot: auth-worker(default): mysql: Connected to 192.168.33.3 (exim) And in the syslos there is nothing about Dovecot... Any idea? Thanks a lot! Luca Bertoncello (lucabert(a)lucabert.de)

LMTPS : TLS over LMTP not working
by Stanislas SABATIER 17 Nov '14

17 Nov '14

Hello, I tried to activate SSL on LMTP service, to secure connections between Postfix and Dovecot on my LAN, but Dovecot is not negociating a TLS session with Postfix. If I enforce TLS for LMTP at Postfix's side, communication between Postfix and Dovecot is not working. I put ssl = yes ssl_cert = </dovecot/ssl/ssl-LMTP.pem ssl_key = </dovecot/ssl/ssl-LMTP.key in section protocol LMTP within 20-lmtp.conf and service lmtp { inet_listener lmtp { name = dovecot_lmtp address = xx.xx.xx.xx port = 26 ssl = yes } process_min_avail = 5 } within 10-master.conf Did I miss something ? Thank you for your help. Regards, Stan

inbox parameter is ignored within location config for public namespaces?
by Dieter Knopf 17 Nov '14

17 Nov '14

Hello, i already asked a similiar question some month ago but still have no fix for my problem :-( This is my global location option in 10-mail.conf: mail_location = maildir:/home/vmail/%d/%n/MAILDIR:INBOX=/home/vmail/%d/%n/MAILDIR/.INBOX:INDEX=/home/vmail/%d/%n/INDEX/ This works fine, until i'm using a public namespace. The following namespace is a normal user too, every mail to bos(a)foo.eu is stored in /home/vmail/foo.eu/bos/MAILDIR (within the INBOX-folder) and this directory is used for the location of the namespace. Config: namespace { type = public separator = / prefix = BOS/ location = maildir:/home/vmail/foo.eu/bos/MAILDIR:INBOX=/home/vmail/foo.eu/bos/MAILDIR/.INBOX:INDEX=/home/vmail/foo.eu/bos/S_INDEX:INDEXPVT=/home/vmail/foo.eu/bos/S_INDEXPVT/%u subscriptions = yes } The namespace itself works fine and without a problem, but the INBOX folder is the main problem. Mail users agents like Thunderbird now shows a folder structure like: BOS (grey, not useable) - INBOX (the .INBOX folder) - Other folder 1 - Other folder 2 - Other folder 3 The INBOX-config works fine for every single user, but it don't work on namespaces? Is this a bug? Thanks Dieter

A6 Yes, but be aware of the following point. A file descriptor is a reference to an open file description (see open(2)). Whenever a descriptor is duplicated via dup(2), dup2(2), fcntl(2) F_DUPFD, or fork(2), a new file descriptor referring to the same open file description is created. An open file description continues to exist until all file descriptors referring to it have been closed. A file descriptor is removed from an epoll set only after all the file descriptors referring to the underlying open file description have been closed (or before if the descriptor is explicitly removed using epoll_ctl() EPOLL_CTL_DEL). This means that even after a file descriptor that is part of an epoll set has been closed, events may be reported for that file descriptor if other file descriptors referring to the same under‐ lying file description remain open. So the close(11) should be enough to remove the fd 11 from epoll(10) - -- Steffen Kaiser -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQEVAwUBVGNvlHz1H7kL/d9rAQKYcAf/dJKQGFqi8wZBwG1GevEc+DYJeZYGSUxB YOtMV+szUrVyl+vD0GZNyXKotO6/xn0gipeV1tLTZ1xIg7NIsVcJ2/DC1WENenrE YePmuuX/TQNpj7nOcQiATFtOtenqV9itwm5zrhTN1vzjyVbEnPwhVjsaOAnaUk9u HN/BdxTazDd7QTEQmJNMKJBFyg/Im0ktJpo/eAKuysv/mcZ9HOorTQhtocK7Goro YqOWacuEZVA0TUtD1hqDn9OfvEymp0oPoM8gEYON7lK4OQ9d6+hWMpkH5BG5x+7Z ZPmq9xUJW17tcbe2imKkXw+RBRNofgf5GyhMwNVoLhbOKa29tYWqXw== =yIiy -----END PGP SIGNATURE-----

Optional mail attribute in ldap
by Alexandros Soumplis 17 Nov '14

17 Nov '14

Hello, I am using an ldap database (active directory) for dovecot authentication and I am trying to change the mail location for some users only, thus any mail should be delivered to the default location unless the ldap query returns a successful result which defines the mail variable. I have chosen the AD atttribute "otherMailbox" and added for the required user the value "=mail=mdbox:/newmailboxes/%Lu/". It seems not to work and mails still get delivered to the default location. Any suggestions ? a.

Understanding filesystem quotas
by Chris Szilagyi 15 Nov '14

15 Nov '14

Hello: I've been trying to set up filesystem quotas for IMAP, and cannot seem to get it to work. In IMAP clients it either shows quota unavailable or unknown. I've read the documentation several times. I've enabled the quota plugins and to my knowledge that part is good. I've edited the file 90-quota.conf and uncommented these lines and set them as follows: plugin { quota_rule = *:storage=1G } plugin { quota = fs:User quota:user } To my knowledge, this should enable filesystem quotas by user. However when I run "doveadm quota get -u username", it shows: Quota name Type Value Limit % User quota STORAGE 0 - 0 So basically all zeros. I've also tried running "doveadm -Dv quota get -u username" and don't see anything that stands out or that would indicate an issue. It shows the correct block device and such. I know filesystem quotas are working as I can run "quota username" and it shows the usage. The reason I picked filesystem quotas is because we have /var/spool/mail/username (spool file), and /home/username/mail on the same partition, and because it sounds like it's fast and doesn't require disk I/O. But I'm trying to also figure out by setting the "storage=" command in Dovecot, do I even need to set a hard and soft limit on the filesystem quota then? I would prefer to let Dovecot enforce quotas rather than rely on the filesystem quota mechanism, but keep disk I/O down. Any help would be greatly appreciated on this. Thank you. -- Chris

Using dovecot-lda with sendmail
by Chris Szilagyi 15 Nov '14

15 Nov '14

Hello: I'm trying to get dovecot-lda to work with sendmail on a CentOS 7 server. I've tried following the instructions at the wiki, http://wiki2.dovecot.org/LDA/Sendmail, by adding the lines to /etc/mail/sendmail.mc, recompiling to /etc/mail/sendmail.cf and restarting sendmail -- the process for any sendmail config change. However it is still not working and in the maillog, it shows: sendmail[31949]: sAEM4GTt031742: to=<user@localhost>, ctladdr=<test@localhost> (1000/1000), delay=00:08:31, xdelay=00:00:00, mailer=local, pri=210942, dsn=4.0.0, stat=Deferred: local mailer (/usr/libexec/dovecot/dovecot-lda) exited with EX_TEMPFAIL I verified that SELinux is not interfering in this case. I see talk of having sendmail run /usr/libexec/dovecot/dovecot-lda as other users, but I see that the file on my system is uid/gid as: root/root. Is there a way to get this working? Thanks much! -- Chris

Evolution clientware and Dovecot
by The Doctor 14 Nov '14

14 Nov '14

Got a customer using Evolution 2.12.3 and was using SSL and could not retrieve e-mail in the last week. Got the custome to turn off SSL and he was able to retrieve e-mail. Recently I compiled SSL so that any comprimise was removed and then all apps using SSL including dovecot was recompiled. Could this be an app/Evolution issue? -- Member - Liberal International This is doctor@@nl2k.ab.ca Ici doctor@@nl2k.ab.ca God,Queen and country!Never Satan President Republic!Beware AntiChrist rising! http://www.fullyfollow.me/rootnl2k Look at Psalms 14 and 53 on Atheism Lest we forget 2014

Dovecot wiki LMTP description
by Ron Leach 14 Nov '14

14 Nov '14

List, we are planning a new configuration to which we'll migrate an existing installation shortly. We are hoping to use Dovecot LMTP and have a query about the wiki entry for LMTP http://wiki2.dovecot.org/LMTP where it suggests this config: service lmtp { inet_listener lmtp { address = 192.168.0.24 127.0.0.1 ::1 port = 24 } Does this example mean that LMTP will only listen for input messages from the interface with IP address 192.168.0.24 (plus localhost)? If so, I probably haven't understood how LMTP is intended to work. Is there a reason why we want to limit LMTP to listening for messages from a specific IP on the network? I need to understand that so that I replace ...24 with a suitable host interface that exists on our LAN (we don't have a host at 192.168.0.24). Apologies for what must seem, to people using LMTP, a very basic question. Nevertheless, I would be grateful for any clarification. regards, Ron

Dovecot Cur and New Directories are empty
by Nguyen Dinh Phuoc Thanh 14 Nov '14

14 Nov '14

Hi, Recently, we faced an issue with dovecot.

automatically create Spam mailbox
by Cliff Hayes 14 Nov '14

14 Nov '14

I am trying to set up dovecot to automatically create a Spam mailbox for every user. http://wiki2.dovecot.org/MailboxSettings shows how to do this but not what config file to put it in so I assume 10-mail.conf. When I put it in there as follows... namespace inbox { mailbox Spam { auto = create special_use = \Junk } } ... I get the following error ... doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/10-mail.conf line 107: Unknown setting: mailbox How do I create the mailbox?

Core Dump upon startup (SEGV) - v2.2.10

In my recent messages I mentioned how I was having difficuilty in making my wife's email readable in Squirrelmail; this was solved with directory permissions. However, my usual email client is Thunderbird; I was holding off on using that as there appeared to be authentication issues. Today was my opportunity to start debugging those; it occurred to me that I might have issues with PKI and tried to make/install working certificates. When this didn't work, I though to just scrub the installation and start over. On my CentOS 7 system I erased and reinstalled from RPM. With what should have been working certificates, I ran through the config files, and then restarted to the following error: [root@dungeon dovecot]# systemctl -l status dovecot.service dovecot.service - Dovecot IMAP/POP3 email server Loaded: loaded (/usr/lib/systemd/system/dovecot.service; disabled) Active: failed (Result: core-dump) since Thu 2014-11-13 19:05:52 EST; 30min ago Process: 23700 ExecStart=/usr/sbin/dovecot -F (code=dumped, signal=SEGV) Process: 23695 ExecStartPre=/usr/libexec/dovecot/prestartscript (code=exited, status=0/SUCCESS) Main PID: 23700 (code=dumped, signal=SEGV) Nov 13 19:05:52 dungeon.the-leveys.us systemd[1]: Started Dovecot IMAP/POP3 email server.

Migrate system users to virtual users
by Ron Leach 13 Nov '14

13 Nov '14

List, good afternoon, We are at the planning stage of wanting to migrate from an existing installation onto a new machine, and also to change from system users to virtual users. May I check that our ideas for user id are correct? I am not sure whether we will encounter a 'permissions' and 'user id' problem when moving from a system-user scheme to a virtual scheme. We use Maildir, and the maildirs at the moment are in their users' linux /home directories. After reading the wiki, we think that the 'single system user for vmail' arrangement, ie just one system user to manage all the mail for all virtual users, will work for us. I think that means that the permissions on all our existing 'system-user-oriented' maildirs will have to be changed (in the new machine) so that they are owned by the 'single-system-user', such as 'vmail'. One thought was to first copy the existing maildirs into the new virtual user file system tree, and then, second, change the owners and permissions on the maildirs and directories and messages to permit control by 'vmail'. From the point of view of transferring all the mail files, is that all we would have to do? (Of course, we would also have to create the virtual users and their passwords, and arrange the appropriate password lookups etc, but that's not the direct topic of this post. And that arrangement has to be compatible with the MTA, as well.) If we do copy the maildirs and change the permissions, does all the metadata that the clients, or Dovecot, use to detect new, existing, or downloaded mail remain valid? Or should we use a different approach? Grateful for any comment regards, Ron

Bug (?) while listing imap folder

Dear All, I think I've hit a bug after migrating our mail server to the newest version of dovecot (version 2.2.15). When I try to list all imap folders for one user the imap process crashes. The listing to a specific folder (ex. INBOX) works fine, only the "*" crashes. Client side: --------------------- [root@mb log]# telnet 127.0.0.1 143 Trying 127.0.0.1... Connected to 127.0.0.1.

Hi, after upgrade to Dovecot >= 2.2.14rc1 sometimes I found this error/crash in the log (never happened with 2.2.13), I'm the only one? Can be fix? Nov 11 17:44:26 imap(info(a)myemail.com): Error: Corrupted transaction log file /home/domains/myemail.com/info/Maildir/dovecot.index.log seq 190: Invalid transaction log size (32756 vs 32772): /home/domains/myemail.com/info/Maildir/dovecot.index.log (sync_offset=32756) Nov 11 17:44:26 imap(info(a)myemail.com): Error: Log synchronization error at seq=0,offset=0 for /home/domains/myemail.com/info/Maildir/dovecot.index: Append with UID 10777, but next_uid = 10778 Nov 11 17:44:26 imap(info(a)myemail.com): Error: /home/domains/myemail.com/info/Maildir/dovecot.index view syncing failed to apply changes Nov 11 17:44:26 imap(info(a)myemail.com): Panic: file index-sync.c: line 265 (index_mailbox_sync_next_expunge): assertion failed: (range->seq2 <= ctx->messages_count) Nov 11 17:44:26 imap(info(a)myemail.com): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x75e1a) [0x7fbbd213ae1a] -> /usr/lib/dovecot/libdovecot.so.0(+0x75e96) [0x7fbbd213ae96] -> /usr/lib/dovecot/libdovecot.so.0(i_error+0) [0x7fbbd20ec2bf] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0xb219c) [0x7fbbd245719c] -> dovecot/imap(imap_sync_more+0xc3) [0x41fd13] -> dovecot/imap() [0x420437] -> dovecot/imap(cmd_sync_delayed+0x209) [0x4208f9] -> dovecot/imap(client_handle_input+0x1ed) [0x4178dd] -> dovecot/imap(client_input+0x6f) [0x417b9f] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x5b) [0x7fbbd214c0db] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0xaf) [0x7fbbd214d27f] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x9) [0x7fbbd214c169] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7fbbd214c1f8] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7fbbd20f1193] -> dovecot/imap(main+0x2b0) [0x4210d0] -> /lib/libc.so.6(__libc_start_main+0xfd) [0x7fbbd1d81cad] -> dovecot/imap() [0x40bea9] Nov 11 17:44:26 imap(info(a)myemail.com): Fatal: master: service(imap): child 13586 killed with signal 6 (core dumped) # gdb /usr/libexec/dovecot/imap /home/domains/myemail.com/info/core Reading symbols from /usr/libexec/dovecot/imap...done. warning: Can't read pathname for load map: Input/output error.

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. Query: SELECT "INBOX" Reason Given: [NOPERM] Permission denied I have see similar errors in my searches, but they all relate to *creating* files (inbox, sent, etc). The files do already exist here, they used to work in the same directory structure on the old server configuration, and I can see no relative difference between this user's files/permissions and working users' files/permissions. Suggestions are welcome; thanks in advance, -Don Here are the vitals: Version: 2.2.10 OS: CentOS 7 # 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux 3.10.0-123.9.3.el7.x86_64 x86_64 CentOS Linux release 7.0.1406 (Core) ext3 auth_mechanisms = plain login disable_plaintext_auth = no log_path = /var/log/dovecot.log mail_location = mbox:/home/%u/~mail:INBOX=/var/spool/mail/%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 } ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } [root@dungeon sandra]# ls -la /var/spool/mail total 2097152 drwxrwxr-x. 2 root mail 4096 Nov 11 22:10 . drwxr-xr-x. 16 root root 4096 Nov 11 14:21 .. -rw-rw----. 1 sandra mail 625547161 Nov 11 21:32 sandra -rw-rw----. 1 spamtrap_000 mail 26773946 Nov 11 20:53 spamtrap_000 -rw-rw----. 1 spamtrap_001 mail 3092961 Nov 11 22:10 spamtrap_001 -rw-rw----. 1 spamtrap_002 mail 8778257 Nov 11 00:03 spamtrap_002 -rw-rw----. 1 spamtrap_003 mail 63579856 Nov 11 21:21 spamtrap_003 Her directory: [root@dungeon .imap]# ls -la total 100 drw-------. 25 sandra sandra 4096 Jul 1 2008 . drwx------. 4 sandra sandra 4096 Nov 10 10:48 .. drwx------. 2 sandra sandra 4096 Jul 1 2008 bday drwx------. 2 sandra sandra 4096 Jul 1 2008 beads drwx------. 2 sandra sandra 4096 Jul 1 2008 books drwx------. 2 sandra sandra 4096 Jul 1 2008 Drafts drwx------. 2 sandra sandra 4096 Jul 1 2008 ham drwx------. 2 sandra sandra 4096 Nov 11 21:39 INBOX drwx------. 2 sandra sandra 4096 Jul 1 2008 Sent drwx------. 2 sandra sandra 4096 Jul 1 2008 spam drwx------. 2 sandra sandra 4096 Jul 1 2008 Trash drwx------. 2 sandra sandra 4096 Jul 1 2008 Work A working directory: [root@dungeon .imap]# ls -la total 56 drwx------. 14 spamtrap_003 spamtrap_003 4096 Oct 23 19:22 . drwx------. 3 spamtrap_003 spamtrap_003 4096 Nov 10 09:15 .. drwx------. 2 spamtrap_003 spamtrap_003 4096 Jun 8 08:40 Deleted Messages drwx------. 2 spamtrap_003 spamtrap_003 4096 Aug 11 2011 Drafts drwx------. 2 spamtrap_003 spamtrap_003 4096 Mar 18 2011 ham drwx------. 2 spamtrap_003 spamtrap_003 4096 Nov 11 21:21 INBOX drwx------. 2 spamtrap_003 spamtrap_003 4096 Oct 18 2013 Sent drwx------. 2 spamtrap_003 spamtrap_003 4096 Aug 28 09:55 Sent Messages drwx------. 2 spamtrap_003 spamtrap_003 4096 Oct 6 20:11 spam drwx------. 2 spamtrap_003 spamtrap_003 4096 Nov 11 21:21 Trash

I am using dovecot in mbox format. I'm going to set to leave the 30-day mail to the server with the mail client. The other day, some of email was received duplicate When receive mail.

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?

mail location change results in various errors
by Cliff Hayes 10 Nov '14

10 Nov '14

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.

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

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.

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

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,

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. One related question, the quota units are only Kb,M,G ? not possible to define it in bytes? > -----Original Message----- > From: dovecot [mailto:dovecot-bounces@dovecot.org] On Behalf Of Jorge > Bastos > Sent: sábado, 8 de Novembro de 2014 14:22 > To: 'Dovecot Mailing List' > Subject: Help on dict with QUOTA / perms > > I'm setting up quota for my users, my users have a UID starting on > >5000 and GID = 5000, and when I query the quota, for example in IMAP, > I get: > > > > Nov 8 14:13:28 fastmail dovecot: imap-login: Login: user=<a(a)a.com>, > method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=18660, secured, > session=<uByciFkH2gB/AAAB> > > Nov 8 14:13:37 fastmail dovecot: imap(a(a)a.com): Error: > net_connect_unix(/var/run/dovecot/dict) failed: Permission denied > (euid=5000(<unknown>) egid=5000(<unknown>) missing +r perm: > /var/run/dovecot/dict, dir owned by 0:0 mode=0755) > > > > Question is, should I have the GID on the users set to 0, or is there > another way to workaround it? > > > > Thanks,

Help on dict with QUOTA / perms

I'm setting up quota for my users, my users have a UID starting on >5000 and GID = 5000, and when I query the quota, for example in IMAP, I get: Nov 8 14:13:28 fastmail dovecot: imap-login: Login: user=<a(a)a.com>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=18660, secured, session=<uByciFkH2gB/AAAB> Nov 8 14:13:37 fastmail dovecot: imap(a(a)a.com): Error: net_connect_unix(/var/run/dovecot/dict) failed: Permission denied (euid=5000(<unknown>) egid=5000(<unknown>) missing +r perm: /var/run/dovecot/dict, dir owned by 0:0 mode=0755) Question is, should I have the GID on the users set to 0, or is there another way to workaround it? Thanks,
