[Dovecot] Replication file sizes
by IT geek 31 16 Jan '14

Hi, I'm using Dovecot 2.2.9 to replicate my mailbox to a remote server. My mailbox on ServerA is 235Mb, but on ServerB it ends up being 358Mb. Does anyone know why this is? Shouldn't they be the same size? doveconf -n from ServerA: # 2.2.9: /usr/pkg/etc/dovecot/dovecot.conf # OS: NetBSD 5.2 cobalt auth_mechanisms = plain login doveadm_password = secret doveadm_port = 12345 first_valid_uid = 1003 last_valid_uid = 1020 listen = 192.168.1.1 mail_location = mbox:~/mail:INBOX=/var/mail/%u mail_plugins = " notify replication" passdb { driver = passwd } plugin { mail_replica = tcp:serverb.test.com } protocols = imap service aggregator { fifo_listener replication-notify-fifo { mode = 0666 } unix_listener replication-notify { mode = 0600 } } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = root } service doveadm { inet_listener { port = 12345 } } service imap-login { inet_listener imap { port = 0 } } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { mode = 0600 } } ssl_cert = </etc/openssl/certs/servera.test.com.crt ssl_key = </etc/openssl/private/serverb.test.com.key userdb { driver = passwd } protocol lda { postmaster_address = postmaster(a)test.com

[Dovecot] mail-filter always results in corrupted indexes
by martijn.list 16 Jan '14

Hi, I'm experimenting with the mail-filter plugin but whenever I add anything to a message, it always results in an corrupted cache: from the logs: Dec 14 16:09:55 ciphermail-webmail dovecot: imap(martijn=djigzo.com(a)ciphermail.private): Error: Corrupted index cache file /var/vmail/martijn=djigzo.com(a)ciphermail.private/dovecot.index.cache: Broken physical size for mail UID 76 Dec 14 16:09:55 ciphermail-webmail dovecot: imap(martijn=djigzo.com(a)ciphermail.private): Error: read() failed: Invalid argument Dec 14 16:10:02 ciphermail-webmail dovecot: imap(martijn=djigzo.com(a)ciphermail.private): Error: Cached message size smaller than expected (773 < 777) Dec 14 16:10:02 ciphermail-webmail dovecot: imap(martijn=djigzo.com(a)ciphermail.private): Error: Maildir filename has wrong S value, renamed the file from /var/vmail/martijn=djigzo.com@ciphermail.private/cur/1387033802.M114583P9631.ciphermail-webmail,S=773,W=791:2, t A do-nothing filter that just sends the input to the output works but whenever I add something trivial to the message, the cache is always corrupted. I using Dovecot 2.2.9.1 (from the deb archives). I use the following trivial test to add some XXX chars and and later remove them. In mail-filter.sh I append some chars and in mail-filter-out I filter these chars out (this is just a test) cat > /tmp/dovecot-in.txt echo "XXX" >> /tmp/dovecot-in.txt cat /tmp/dovecot-in.txt mail-filter-out: cat > /tmp/dovecot-out.txt sed -i /XXX/d /tmp/dovecot-out.txt cat /tmp/dovecot-out.txt Any idea what I'm doing wrong? Kind regards, Martijn Brinkers

It appears your userdb does not specify GID for a user. Either define it, or ... In share/doc/dovecot/example-config/conf.d/10-mail.conf: # System user and group used to access mails.

[Dovecot] EAGAIN in dict proxy
by Richard Platel 15 Jan '14

15 Jan '14

Hello, We’re using a custom program to manage quotas talking to dovecot via the dovecot dict proxy protocol over a unix socket: plugin { quota = dict:User quota::proxy:/var/run/auth_proxy_dovecot/quotasocket:quota } Dovecot gets slammed with quota requests periodically, seemingly because Thunderbird thought it would be a good idea to hardcode having a quota check at 45 seconds past the minute, and thus every Thunderbird client makes several GETQUOTAROOT requests simultaneously. This causes dovecot to make many client connections to the quota proxy, and many of them fail with EAGAIN. In the log we see: Jan 15 16:52:46 imap25 dovecot: imap(rplatel(a)tucows.com): Error: net_connect_unix(/var/run/auth_proxy_dovecot/quotasocket) failed: Resource temporarily unavailable And the client gets: * QUOTAROOT Spam "User quota"[0d][0a] * QUOTA "User quota" ()[0d][0a] * BAD Internal quota calculation error[0d][0a] 19 OK Getquotaroot completed.[0d][0a] Thunderbird transparently disconnects and reconnects at this point but obviously this is not ideal. Writing some toy programs, I found that even making a forked server with several processes doing nothing but accept()ing on the listening socket, with a high number for the listen queue, it’s easy to overwhelm it with simultaneous clients who then get EAGAIN. If the clients do indeed immediately try again, they are successful. (An INET listening socket does not seem to have this problem, incidentally) All of this is a long-winded way of saying that I believe in lib-dict/dict-client.c:client_dict_connect() the call to net_connect_unix should be a call to net_connect_unix_with_retries() with a small timeout. It would also be useful for us if an INET socket could be used.

[Dovecot] int/ext mailserver
by Mr.Pine 15 Jan '14

15 Jan '14

I 'm using potfix-dovcote as an internal mail server(local.myco.com) and wan to run another potfix-dovcote as an external mail server (myco.com) on Internet.75% of my users should only work internally(no external mail) but the rest of users (25%)should be able to send mail to external network! These users have the same username on myco.com. I use smtp_generic_maps to map int username of these users to ext. one. For eg. All email send by test(a)local.myco.com map to test(a)myco.com. So anyone got these mails can reply them. I know that getmail is the tools that can get mails from users external mailbox and put them into int. mailbox. 1. I have a root access to ext mail server. But do not know my ext user password!. How can I use getmail to move ext mail to internal one?! 2. What is your idea about syncing users password in internal/external mail server?! I think its needed for getmail! 3. How can I restrict my internal users to send mail only internally!? I appreciated any help!! TNX

[Dovecot] restored mails
by Wojciech Giel 15 Jan '14

Hello, I am running dovecot 2.1 on debian wheezy . We are using maildir format. one of our uses deleted content of INBOX folder during xmass. he wants these messages back. I had these mail on tape. I have restored them to his inbox/cur directory but dovecot is not indexing them. Email client shows empty inbox as well. tried manually run: doveadm index -u john -q INBOX no change. deleting indexes didn't help.

[Dovecot] Why does dovecot require the {} password sheme even if there is a $ crypt scheme.
by da-dovecotlist-15＠abelonline.de 15 Jan '14

15 Jan '14

The wiki[1] says: If all the passwords are in same format, you can use default_pass_scheme to specify it. Otherwise each password needs to be prefixed with "{password-scheme}", for example "{plain}plaintext-password". Why doesn't dovecot recognize the crypt scheme identifier ($1$ for MD5-CRYPT, $6$ for SHA512-CRYPT etc.)? At the moment I have to have the following in my db for dovecot to work: {SHA512-CRYPT}$6$salt$passwordhash [1]http://wiki2.dovecot.org/AuthDatabase/SQL

[Dovecot] dsync mbox to maildir migration does not delete, deleted e-mails
by A M 15 Jan '14

15 Jan '14

Hello, I am planning to migrate all users from mbox to maildir. I am trying to do it with minimum downtime. (~100GB data) All users are currently using POP3. Dovecot version is 2.2.10 (latest). Command used is: dsync -u username mirror maildir:~/Maildir Process I plan is: (omitting steps related to sendmail / procmail) 1) keep dovecot running (with mail_location as mbox) 2) dsync for all users (this may take 3-4 hours or more) 3) (downtime starts) stop dovecot and sendmail (to stop new e-mails) 4) block pop3, imap ports on firewall (so users can not connect) 5) start dovecot (still with mbox) 6) dsync again to sync e-mails arrived between step 2 and 3 7) dsync again (just to make sure!) 8) (downtime ends) restart dovecot (with mail_location as maildir) Now, here is my problem. Lets say there is user joe, who has 50 NEW e-mails in mbox (INBOX). Step 2 perfectly syncs his 50 e-mails to 'new' folder of maildir. Now in the mean time, before step 3, he connected via POP3 and downloaded and deleted 50 e-mails. Now when we reach step 6 (re-sync), what I expected was dsync will detect that 50 e-mails are deleted and it will delete 50 e-mails from 'new' directory of maildir. But that is not happening. 50 e-mails are still there. I fear that these e-mails will be re-downloaded on his Outlook once I switch dovecot to maildir. This will happen for each and every user which will cause huge mess. So how to tell, dsync to delete non-existent e-mails which are no more there in mbox (INBOX)? Thanks in advance, Regards, A M

[Dovecot] Dovecot service not responding after about a week of uptime
by Matthieu 15 Jan '14

15 Jan '14

Hello, I am running a dovecot 2.1.13 server and lately it stops responding after about a week of uptime. Simply restarting the dovecot service solves the issue. I tried to look a bit in my maillog file but did not find anything obvious. During the time when the server is not responding I can still see imap-login entries from the connection attempt by my email client. Any help about how to diagnose the problem would be appreciated. Thanks, Matthieu

[Dovecot] Dovecot LMTP does not pass envelope recipient +detail to sieve
by Greg Rivers 14 Jan '14

14 Jan '14

I found this[1] thread that describes the same problem with dovecot-LDA, but the solution (add X-Original-To: header) has no effect with LMTP. My sendmail LMTP configuration: FEATURE(`local_lmtp',`[IPC]',`FILE /var/run/dovecot/lmtp') Sendmail's address test indicates that sendmail is providing user+detail to LMTP (see below). Except for this problem, dovecot, LMTP, and sieve are all working perfectly. Is there something I'm missing, or is this a bug?

[Dovecot] Sieve - not functioning for additional email aliases.
by Jacek Osiecki 14 Jan '14

14 Jan '14

Hi, On one of my servers (old one, version 1.2.5) user reported that vacation message for basic address works fine, but not for the aliases. I know that this is an old version, but we can't simply switch them to the most current dovecot release without preparing and testing everything... So I'm rather asking for help with debugging the case :) This person has email my.name(a)olddomain.pl. However, they are switching to new domain - newdomain.pl - and it is becoming their main brand. So temporarily olddomain.pl is still their "home" domain, but there is a domain alias newdomain->olddomain. The sieve file is simple: forward message and reply with vacation: ---- require ["copy","vacation"]; # rule:[redirect] if anyof (true) { redirect :copy "my.boss(a)newdomain.pl"; vacation :days 1 :addresses ["my.name(a)olddomain.pl","my.name(a)newdomain.pl"] text: I'm unavailable now. Please contact my boss: my.boss(a)newdomain.pl Greetings . ; } ---- When I send email to my.name(a)olddomain.pl - it is sent to my.boss(a)newdomain.pl and I receive the vacation message. When I send it to the alias (my.name(a)newdomain.pl) - none of above is done. Any idea how I can debug it? Running test-sieve does not help - it claims that will simply forward and deliver the message... Greetings, -- Jacek Osiecki joshua(a)ceti.pl GG:3828944 I don't want something I need. I want something I want.

[Dovecot] dict ldap
by me＠electronico.nc 14 Jan '14

14 Jan '14

Hello everybody, Dovecot 2.2.6 with LDAP auth against AD (Samba4). I would like to know if it's possible to specify an LDAP transport for dict (something like dovecot-dict-ldap.conf.ext). I'm in need to setup shared mailboxes and if I could query LDAP, that would help a lot. IE : user1 user2 user3 are in OU=group1, so group1 (setup as user in AD) would share its mailbox with user1 user2 and user3. Thanks in advance for your time. Nicolas

[Dovecot] Slow authentication performance when switching folder
by ra＠rz.uni-frankfurt.de 13 Jan '14

13 Jan '14

Hello, we have a problem with Dovecot 2.2.9 running on an AIX 7.1 and compiled with xlc. At first we configured passdb to use our ldap directory via pam and experienced an Internal login failure like the following one Jan 13 16:20:02 imap-login: Info: Internal login failure (pid=29818948 id=1) (internal failure, 1 successful auths): user=<user>, method=PLAIN, rip=xxx.xxx.xxx.xxx, lip=yyy.yyy.yyy.yyy, TLS, session=<r/P1m9vv5ACNAv6j> I read that this error occurs if the last passdb returns a continue and there is no other passdb to ask. We added two more passdb to rule out that pam is the problem. We added ldap directly and as third a fallback passwd file, but we still get the Internal login failure. As far as i can see this only occurs if i switch to another folder and i´m being reauthenticated. Are there any suggestions on what is going wrong? Any push in the right direction would be appreciated. kind regards Manuel PS: This is the dump of our dovecot configuration file: doveconf: Warning: service auth { client_limit=1000 } is lower than required under max. load (32768) doveconf: Warning: service anvil { client_limit=1000 } is lower than required under max. load (24579) # OS: AIX 1 00F7B83D4C00 auth_debug = yes auth_mechanisms = plain login auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890- auth_username_format = %n auth_username_translation = AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz auth_verbose = yes base_dir = /var/run/dovecot-imap default_process_limit = 8192 disable_plaintext_auth = no first_valid_uid = 100 info_log_path = /mailbase/dovecot/2.2.9/log/dovecot_imap_debug.log log_path = /mailbase/dovecot/2.2.9/log/dovecot_imap.log login_greeting = University-Frankfurt-IMAP-Horde ready. mail_access_groups = mhs mail_debug = yes mail_fsync = never mail_location = mbox:~/:INBOX=/var/spool/mail/%u:INDEX=/var/mail-indexes/%u mailbox_idle_check_interval = 90 secs mbox_write_locks = fcntl namespace { inbox = yes location = prefix = separator = / type = private name = } passdb { args = username_format=%u /mailbase/etc/passwd driver = passwd-file } passdb { args = %s driver = pam } plugin { stats_refresh = 30 secs stats_track_cmds = yes } service replication-notify-fifo { name = aggregator } service anvil-auth-penalty { name = anvil } service auth-worker { name = auth-worker } service auth-client { name = auth } service config { name = config } service dict { name = dict } service login/proxy-notify { name = director } service dns-client { name = dns_client } service doveadm-server { name = doveadm } service { inet_listener { address = * port = 0 name = imap } inet_listener { address = * port = 993 name = imaps } name = imap-login } service imap-urlauth { name = imap-urlauth-login } service imap-urlauth-worker { name = imap-urlauth-worker } service token-login/imap-urlauth { name = imap-urlauth } service login/imap { name = imap } service indexer-worker { name = indexer-worker } service indexer { name = indexer } service ipc { name = ipc } service lmtp { name = lmtp } service log-errors { name = log } service { inet_listener { address = 10.1.1.40 port = 0 name = pop3 } inet_listener { address = * port = 0 name = pop3s } name = pop3-login } service login/pop3 { name = pop3 } service replicator-doveadm { name = replicator } service login/ssl-params { name = ssl-params } service stats-mail { name = stats } ssl_cert = </etc/ssl/certs/thot_mit_chain.crt ssl_key = </etc/ssl/certs/private_key_thot.rz.pem userdb { driver = passwd } userdb { args = /mailbase/dovecot/2.2.9/etc/dovecot/dovecot-ldap.conf driver = ldap } protocol imap { mail_plugins = " stats imap_stats" service replication-notify-fifo { name = aggregator } service anvil-auth-penalty { name = anvil } service auth-worker { name = auth-worker } service auth-client { name = auth } service config { name = config } service dict { name = dict } service login/proxy-notify { name = director } service dns-client { name = dns_client } service doveadm-server { name = doveadm } service imap { name = imap-login } service imap-urlauth { name = imap-urlauth-login } service imap-urlauth-worker { name = imap-urlauth-worker } service token-login/imap-urlauth { name = imap-urlauth } service login/imap { name = imap } service indexer-worker { name = indexer-worker } service indexer { name = indexer } service ipc { name = ipc } service lmtp { name = lmtp } service log-errors { name = log } service pop3 { name = pop3-login } service login/pop3 { name = pop3 } service replicator-doveadm { name = replicator } service login/ssl-params { name = ssl-params } service stats-mail { name = stats } }

it's possible to send email from the system after the mailbox quota is full i don't want warning mail i want something else because when i use warning on 100% or 99% or less some times the last message be too large (so if just 5% is free from quota size and the last msg size is 6% from quota ) after that the mailbox will not receive this message or warning message . -- View this message in context: http://dovecot.2317879.n4.nabble.com/it-s-possible-to-send-email-from-the-s… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] dsync error: gz trailer has wrong CRC value
by Joe Beaubien 13 Jan '14

13 Jan '14

A few days ago by dovecot installation started behaving weirdly. First it was doveadm fts optimize which would fail (a thread running about that) and now it's dsync, which means my backups are not working. This all started a few days ago, which I find a little weird, because I haven't messed around with the dovecot setup in months. I've been searching the internet, but didn't find anything useful yet. Would anyone know how to fix the errors in the log below? Thanks, -Joe dovecot version is 2.1.7 Here is the log: dsync(archive): Error: zlib.read(/mba_data/emails/archive/storage/m.1885): gz trailer has wrong CRC value at 16966298 dsync(archive): Error: zlib.read(/mba_data/emails/archive/storage/m.1885): missing gz header at 16973513 dsync(archive): Error: zlib.read(/mba_data/emails/archive/storage/m.1885): missing gz header at 16973513 dsync(archive): Error: zlib.read(/mba_data/emails/archive/storage/m.1885): missing gz header at 16973513 dsync(archive): Error: zlib.read(/mba_data/emails/archive/storage/m.1885): missing gz header at 16973513 dsync(archive): Error: zlib.read(/mba_data/emails/archive/storage/m.1885): missing gz header at 16973513 dsync(archive): Error: read(msg input) failed: Invalid argument dsync(archive): Error: zlib.read(/mba_data/emails/archive/storage/m.1885): missing gz header at 16973513 dsync(archive): Panic: file mail-index-transaction-update.c: line 906 (mail_index_update_ext): assertion failed: (seq > 0 && (seq <= mail_index_view_get_messages_count(t->view) || seq <= t->last_new_seq)) dsync(archive): Error: Raw backtrace: /opt/dovecot-2.1.7/lib/dovecot/libdovecot.so.0(+0x4203a) [0x7f3a5150503a] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot.so.0(default_fatal_handler+0x2a) [0x7f3a515050fa] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7f3a514dc3f0] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot-storage.so.0(mail_index_update_ext+0x1c7) [0x7f3a51804927] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot-storage.so.0(+0xa8746) [0x7f3a517f7746] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot-storage.so.0(mail_cache_transaction_commit+0x4c) [0x7f3a517f7a2c] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot-storage.so.0(+0xa8af3) [0x7f3a517f7af3] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot-storage.so.0(+0xa2cea) [0x7f3a517f1cea] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot-storage.so.0(mail_index_transaction_commit_full+0x84) [0x7f3a51800754] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot-storage.so.0(index_transaction_commit+0x8a) [0x7f3a517f209a] -> /opt/dovec ot/lib/d ovecot/lib20_zlib_plugin.so(+0x3b7a) [0x7f3a4fe8cb7a] -> /opt/dovecot/lib/dovecot/lib20_fts_plugin.so(+0xb481) [0x7f3a5009b481] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot-storage.so.0(mailbox_transaction_commit_get_changes+0x3d) [0x7f3a517c9c4d] -> /opt/dovecot/bin/dsync() [0x4297e6] -> /opt/dovecot/bin/dsync() [0x42b222] -> /opt/dovecot/bin/dsync(dsync_worker_select_mailbox+0x2e) [0x4291be] -> /opt/dovecot/bin/dsync() [0x424c75] -> /opt/dovecot/bin/dsync() [0x424db7] -> /opt/dovecot/bin/dsync(dsync_brain_msg_sync_more+0x22c) [0x4245ec] -> /opt/dovecot/bin/dsync(dsync_brain_sync+0x459) [0x422fc9] -> /opt/dovecot/bin/dsync() [0x423e61] -> /opt/dovecot/bin/dsync(dsync_brain_sync+0x7f1) [0x423361] -> /opt/dovecot/bin/dsync() [0x423cdc] -> /opt/dovecot/bin/dsync(dsync_brain_sync+0x832) [0x4233a2] -> /opt/dovecot/bin/dsync(dsync_brain_sync_all+0x18) [0x423ee8] -> /opt/dovecot/bin/dsync() [0x420f36] -> /opt/dovecot/bin/dsync() [0x4215b2] -> /opt/dovecot/bin/dsync() [0x40e798]

[Dovecot] Dovecot quota with MySQL - username issue
by michael 11 Jan '14

11 Jan '14

Hi all, I'm using Dovecot 2.2.8 with quota using a MySQL backend. The Quota plugin is listed for POP3, IMAP and LDA. When it is enabled for LDA, it populates the "username" field in the MySQL table with e mail addresses. I end up with a mixture of email addresses and usernames, which causes things to not fully work. It *should* be just usernames. the LDA SQL statement is: user_query = \ SELECT mailboxes.username, accounts.uid, accounts.uid AS gid, \ concat('/home/',mailboxes.username) AS home, \ (SELECT IF(accounts.new_mail_fmt=1, \ CONCAT('Maildir:',home,'/Maildir'), \ CONCAT('mbox:',home,'/Maildir:INBOX=/var/spool/mail/',mailboxes.username))) AS mail_location \ FROM mailboxes JOIN accounts ON accounts.username=mailboxes.username \ WHERE (mailboxes.email='%u' || \ (mailboxes.email=CONCAT('@','%d') AND (SELECT COUNT(email) FROM mailboxes \ WHERE email='%u') = 0) AND mailboxes.active IS TRUE) It clearly knows the username. Usernames on this system are just names, not full email addresses. The configuration of Quota Dict is: dovecot.conf dict/quotadict = mysql:/etc/dovecot/dovecot-dict-sql.conf ... quota = dict:user::proxy::quotadict dovecot-dict-sql.conf map { pattern = priv/quota/storage table = quota username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota username_field = username value_field = messages } Can this be fixed?

[Dovecot] Possible to force cipher order?
by Matthias Rieber 10 Jan '14

10 Jan '14

Hi, is it possible to force the server cipher order instead of the clients preferences? When I connect with openssl using these ciphers: 'RC4-SHA:DHE-RSA-AES256-GCM-SHA384' -> RC4-SHA will be selected and with 'DHE-RSA-AES256-GCM-SHA384:RC4-SHA' -> DHE-RSA-AES256-GCM-SHA384 It seems to be recommended for webservers to override that due to bad clients choices and increasing knowledge, like RC4 vs. BEAST, AES128 better (theoretical) than AES256. Regards, Matthias

[Dovecot] Message filtering capability at IMAP proxy
by CM Reddy 10 Jan '14

10 Jan '14

Hi, I would like process the messages at Dovecot IMAP proxy. In one of the documents, it was mentioned that Dovecot proxy currently supports on the fly message filtering in latest releases. Will it it possible to extend the filtering feature to handle the following requirements. 1. Parse the email at IMAP proxy. 2. Replace the links with some other secure links. 3. Replace the attachments with some other document. It would be great, if any one can provide some pointers to move forward. - Thanks in advance CM Reddy

[Dovecot] imap auto create mailbox: we're not in group 8(mail)
by Adrian Zaugg 09 Jan '14

09 Jan '14

Dear List Somehow I don't understand the intended work flow to have new mailboxes auto created. On login of a new user with no mailbox, I get 2014-01-09 12:53:06 imap(tester): Error: user tester: Initialization failed: Namespace '': mkdir(/var/mail/tester) failed: Permission denied (euid=1016(tester) egid=1016(tester) missing +w perm: /var/mail, we're not in group 8(mail), dir owned by 0:8 mode=0771) The imap process runs as the user the login performed and thus it has only the privileges of that user. This is good and desired, when a mailbox already exists. I do not want to allow all users to write to /var/mail, only they should write to their dirs inside /var/mail.

[Dovecot] Disallow certain characters in foldernames?
by Charles Marcus 08 Jan '14

08 Jan '14

Is there a way to do this in dovecot? Similar to how you can When using Maildir and Thunderbird, if a user tries to a create folder named "test.1" or "test/1", dovecot will happily create a folder called "test", with a subfolder called "1". Worse, the top level folder "test" is greyed out, which is how Thunderbird displays a folder that can contain only other folders, not both folders and files. I want to disallow this. Obviously I'd prefer if Thunderbird would display a meaningful error, but most likely dovecot cannot control that. I don't really care if the user just gets some kind of weird generic error or not, I'd just prefer to prevent dovecot from creating the problematic folders, and explain the problem to the user if/when they call about it (after NOT reading my carefully crafted documentation explaining the illegal characters that cannot be used in foldernames). -- Best regards, Charles

[Dovecot] acl, shared folders

Hi list, After spending quite some time to figure out how users can share folders I now hope someone of you could help me out. I am quite sure its just a stupid mistake/misunderstanding ... I am using Ubuntu 12.04 LTS with the shipped dovecot 2.0.19 When I login via telnet as user1 I get the following: 1 create folder1 1 OK Create completed. 2 setacl folder1 user2 rli 2 OK Setacl complete. 3 getacl folder1 * ACL "folder1" "user2" ilr "user1" lrwstipekxacd 3 OK Getacl completed. This seems fine. However, there is nothing listed in the account of user2. I think the mistake is in the namespace configuration of "location" or "prefix" Please help!

[Dovecot] LMTP with virtual and system users
by Philipp Kolmann 08 Jan '14

08 Jan '14

Hi, I have a mailsystem where i have some local users with shell access and full home dirs which receive mail and also several SQL virtual users only for mail. With the virtual users, everything works fine. Mail is delivered via LMTP and also sieve works :) The SQL Lookup knows what to do with username(a)domain.com The problem is the system user. If exim delivers the mail to the lmtp socket, the LMTPd can't find username(a)local.host I would be able to specify the global auth_username_format=%n but then my SQL queries break and I like the possibility to have xx(a)domain1.com and xx(a)domain2.com routed to two different accounts. As I have seen in the source, I can't specify username_format=%n in the passdb { driver = pam } backend. Do you have any suggestion how to solve this issue? thanks Philipp

[Dovecot] Question re: filesystem permissions
by Charles Marcus 08 Jan '14

08 Jan '14

Hi all, I want to make sure the filesystems are correct/optimal and secure as possible. This is a virtual hosting setup only (no system users), and dovecot is currently running in high performance mode (I'm thinking I want to change that too, so wondering if that would affect the permissions)... /var/vmail (and everything under it) is owned by vmail:vmail. Current permissions are: /var/vmail 755 /var/vmail/example1.com 777 /var/vmail/example2.com 777 /var/vmail/example1.com/user1 755 (all other user home dirs are the same) /var/vmail/example1.com/user1/Maildir 700 (all other user Maildirs and all subdirs are the same) All files are 600, with the exception of the dovecot-uidvalidity.blahblah files, which are 444 So... is this right? Anything need to be changed? Thanks, -- Best regards, Charles

Hey Joseph! Thanks for testing. > I couldn't recreate this with 2.1.16. Also, my version of "doveadm > search" does not accept missing header patterns. Is this corroborated > by dumping out the header with this same search query? > > doveadm fetch -u exampleuser hdr SUBJECT Silvester \ > HEADER Return-Path someuser at example.com Yes, it's same phenomenon when dumping with fetch. Of course you can only test this properly when you really have some mails with corresponding existing Header fields. (You can also try out other HEADER fields, like Reply-To, References, X-Spam-Score or whatever - just look at some mail headers of your mails and try it with existing fields.) So E.g. When doing doveadm fetch -u exampleuser hdr SUBJECT Silvester HEADER Return-Path someuser(a)example.com it initially outputs 13 headers (same as when using with SUBJECT Silvester only) , when piping it to "grep -i 'Return-Path'" it even found only 3 out of 13 headers containing a Return-Path at all, 2 of them different than someuser(a)example.com - so SAME behaviour as with search.

[Dovecot] how to separate virtual delivery and authentication?
by Mihai Badici 08 Jan '14

08 Jan '14

I have a "pure ldap" setting with postfix and dovecot. When using dovecot delivery, the recipient is checked via ldap. The same ldap query is used when authenticate. So, if I want to authenticate with the uid , I can't use a filter like uid=%u because the delivery will fail. I don't want to use %nor something else because I could use multiple e-mail addresses on a single account. I actually use a filter like ( mail=%u)|(uid=%u) but I think for more complex situations should be better to have two separate filters, one for authentication and the other for the delivery. What is your oppinion? -- Mihai Bădici http://mihai.badici.ro

[Dovecot] Dovecot can't find CLucene's libstemmer on FreeBSD

Hello, A set of patches was created by Lawrence Chen for the Dovecot2 port so that it could recognise and use libstemmer and libexttextcat. They can't be used as is as he's replacing statements with something that works only on FreeBSD, but I think it would be a good idea to try and include some of his fixes. http://www.freebsd.org/cgi/query-pr.cgi?pr=ports/175813 Cheers, Olivier

Re: [Dovecot] using OR in doveadm search query

> > This works for me (at least with tcsh): > > > > $ doveadm search mailbox "shared/* OR (SUBJECT a) (SUBJECT b)" > doveadm does not complain anymore but it does not find anything. I guess > because now the query has become a mailbox name that does not exist. ( I > am using dovecot 2.2.9) Each search token ought to be a command line argument to doveadm, so if you're looking for all message with the string "a" or "b" in the subject in mailboxes shared/*, then this should be the correct syntax, with all arguments sufficiently escaped from shell interpretation: doveadm search mailbox shared/\* $ SUBJECT a OR SUBJECT b $ (Delete "OR" if both strings must be in the subject: expressions are implicitly AND'd if not OR'd. In fact, you can also remove the parenthesis since precedence doesn't matter anymore.) You can check the search query by fetching some values using the same query: doveadm fetch 'mailbox hdr' mailbox shared/\* $ SUBJECT a OR SUBJECT b $ Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Mailbox autocreate feature cannot create folders
by interfaSys sàrl 08 Jan '14

08 Jan '14

Hello, The "new" way of creating default mailboxes doesn't work for us. There seems to be a permission problem. We get this in the logs: imap(testuser(a)domain.com): Error: nfs_flush_file_handle_cache_dir: rmdir(/var/mail) failed: Device busy That error message has nothing to do with NFS (not used) or /var/mail and appears every time an app is requesting a list of folders via IMAP and only if we enable the autocreate feature. We're using mdbox, emails are delivered via LDA and the folder permissions look like this: # la /home/user/imap/domain.com/testuser/mdbox/mailboxes/ total 5 drwx------ 3 user mail 3B Jan 5 19:33 INBOX drwx------ 3 user mail 3B Jan 5 19:33 . drwx------ 4 user mail 8B Jan 7 02:43 .. The mailbox definitions used come straight from the wiki: http://wiki2.dovecot.org/MailboxSettings I've enabled debugging, but there is no mention of the mailboxes to create: Debug: dict quota... Debug: Namespace : type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=mdbox:~/mdbox Debug: fs:... Debug: acl:... ... Here is what works: - Autocreate plugin - Creating folders via various clients So, it seems Dovecot can create folders, just not using that feature. If that's not a bug, would there be a way to make it work without altering permissions? Cheers, Olivier

[Dovecot] need assistance migrating between apple servers
by Raymond Norton 06 Jan '14

06 Jan '14

I am attempting to move imap folders from an Apple Snow Leopard server to a new Apple Mavericks server. Dovecot --version is not working , but I believe the old server is running dovecot 1.1.2 and can confirm the new one is running 2.2.x. I have tried taring and moving folders, but have not been able to get the transfered messages and folders to show up in user accounts (new messages show up fine). I have attempted to recreate index files, but that has not worked either. The last attempt I made to migrate was to use dsync, but it does not exist on the old server and I do not see a way to install it. What method would work best to migrate or move files and folders from the old server and get them to show up for clients on using the new server? -- Raymond Norton LCTN 952.955.7766 Sent from My Desktop

[Dovecot] [SIEVE] Locking Errors with vnd.dovecot.duplicate Extension
by Daniel Parthey 06 Jan '14

06 Jan '14

Hi, we are running a 4 host setup which each hosts a director+mailbox which is mounted via NFSv4 from a DRBD cluster. * Dovecot upstream release 2.1.16 * Doveadm batch subcommand fix - http://hg.dovecot.org/dovecot-2.1/raw-rev/850b5d8bbcc9 * Pigeonhole release 0.3.4 Now we would like to remove duplicate Mails using the vnd.dovecot.duplicate extension using a SIEVE script like this: require ["vnd.dovecot.duplicate", "fileinto", "mailbox", "regex", "vacation", "variables"]; if duplicate { fileinto :create "Trash"; } But as soon as we start delivering duplicate mails, we're sometimes getting locking errors from the mailbox (which is responsible for the user) according to the director: Dec 27 16:36:30 10.129.3.213 dovecot: lmtp(27975, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:33 10.129.3.213 dovecot: lmtp(27987, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:35 10.129.3.213 dovecot: lmtp(27994, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:36 10.129.3.213 dovecot: lmtp(28011, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:36 10.129.3.213 dovecot: lmtp(28013, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:38 10.129.3.213 dovecot: lmtp(28017, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:39 10.129.3.213 dovecot: lmtp(28025, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:42 10.129.3.213 dovecot: lmtp(28037, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:43 10.129.3.213 dovecot: lmtp(27973, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Configs and Error log is attached.

[Dovecot] disable_plaintext_auth = yes not showing in doveconf -n output?

I have it set, but it doesn't show up. However, I noticed that it does show as enabled by default in doveconf -a output. Is this why it doesn't show up in doveconf -n output? -- Best regards, Charles

[Dovecot] RFE: IMAP LIST Extension for Special-Use Mailboxes
by Patrick Ben Koetter 03 Jan '14

03 Jan '14

Timo, would you consider adding support for "IMAP LIST Extension for Special-Use Mailboxes" <http://www.rfc-editor.org/rfc/rfc6154.txt> any time near in the future? I would really love to get rid of all those folders created by all those different mail clients just because they can't agree to use the same folder for special purpose. Obviously clients need to support it too. Having Dovecot support it certainly would make them adopt the standard sooner. p@rick -- state of mind Digitale Kommunikation http://www.state-of-mind.de Franziskanerstraße 15 Telefon +49 89 3090 4664 81669 München Telefax +49 89 3090 4666 Amtsgericht München Partnerschaftsregister PR 563

[Dovecot] Allow both SSL/993 and STARTTLS/143 connections (secure only)
by Charles Marcus 03 Jan '14

03 Jan '14

Hi all, Ok, up until now, I've only always allowed IMAPS connections to dovecot on port 993. I want to also start allowing clients to user port143+STARTTLS, but I walso want to make sure both ports are locked down to ONLY allow secure connections. So... is disable_plaintext_auth = yes in the main config enough to accomplish this? http://wiki2.dovecot.org/SSL/DovecotConfiguration says: There are a couple of different ways to specify when SSL/TLS is required: * disable_plaintext_auth=yes allows plaintext authentication <http://wiki2.dovecot.org/Authentication/Mechanisms> only when SSL/TLS is used first. * ssl = required requires SSL/TLS also for non-plaintext authentication <http://wiki2.dovecot.org/Authentication/Mechanisms>. * If you have only plaintext mechanisms enabled (auth { mechanisms = plain login } ), you can use either (or both) of the above settings. They behave exactly the same way then and the comments in 10-auth.conf say: # Disable LOGIN command and all other plaintext authentications unless # SSL/TLS is used (LOGINDISABLED capability). Note that if the remote IP # matches the local IP (ie. you're connecting from the same computer), the # connection is considered secure and plaintext authentication is allowed. # See also ssl=required setting. #disable_plaintext_auth = yes These seem to be saying that all I need to do is set either or both (ssl-required and/or disable_plaintext_auth=yes). I'm looking for the simplest, and don't like redundant/unnecessary settings, so... which is the best/preferred way? And what is the difference between ssl=required and disable_plaintext_auth=yes? Thanks, -- Best regards, */Charles/***

[Dovecot] Problem building dovecot 2.2.10 with pigeonhole 0.4.2
by Nikolaos Milas 02 Jan '14

02 Jan '14

Hi, I am on CentOS 5.10 x86_64 and I am trying to build RPMs for Dovecot 2.2.10 with pigeonhole 0.4.2. I am getting an error that autogen.sh is missing from pigeonhole 0.4.2 source (as available from: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.2.tar…) /var/tmp/rpm-tmp.89185: line 92: /home/mockbuild/rpmbuild/BUILD/dovecot-2.2.10/dovecot-2.2-pigeonhole-0.4.2/autogen.sh: No such file or directory Indeed, the file is missing, as: tar --list -f dovecot-2.2-pigeonhole-0.4.2.tar.gz | grep autogen ...produces no output. However, I managed to use the latest source code: http://hg.rename-it.nl/dovecot-2.2-pigeonhole/shortlog/32beba3bfd8d which does contain an autogen.sh, and this package worked fine. I guess the released source tar pack should be updated? Thanks and regards, Nick

[Dovecot] Dovecot doesn't seem to read userdb for the first delivery
by phuhimself＠phunehehe.net 02 Jan '14

02 Jan '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hello List, First of all, this is my first post so please bear with me if I miss something. I'm using Postfix with Dovecot 2.0.19 as the LDA. The home directory is of the form `/var/mail/virtual/<domain>/<username>`. The mail directory is under the home directory and named `mail`. `mail_location` is left empty, and userdb is specified using SQL: user_query = SELECT uid AS uid, \ gid AS gid, \ homedir AS home, \ maildir AS mail \ FROM users WHERE email = '%u' Everything had been fine, until I added a new user. In the log, Dovecot complains that it doesn't have permission to create the mail directory (email address replaced): > Jan 2 05:46:19 mail1 dovecot: lda(test(a)test.com): Error: user > test(a)test.com: > Initialization failed: Initializing mail storage from mail_location > setting > failed: mkdir(mail) in directory /var/spool/postfix failed: Permission > denied > (euid=5000(virtual) egid=5000(virtual) missing +w perm: > /var/spool/postfix, > dir owned by 0:0 mode=0755) Sometimes it complains about /run/dovecot instead of /var/spool/postfix, but I think that doesn't really matter. I think not specifying `mail_location` confused Dovecot, as explained in [MailLocation][1]. When I put in the right value for `mail_location` the error went away. What I don't understand is, it is said in the [same document][1] that the userdb field `mail` will override `mail_location` anyway. I would think that I can skip `mail_location` if I specify userdb `mail` for all users. Is the document wrong?

[Dovecot] How to add dovecot plugin?
by Timothy Murphy 31 Dec '13

31 Dec '13

I'm running dovecot version 2.0.9 under CentOS-6.5 . I want to add the following plugin: ==================== require "fileinto"; if header :contains "X-Spam-Flag" "YES" { fileinto "Spam"; } ==================== Could some kind soul tell me where exactly I should place this script (eg "anywhere in /etc/dovecot/dovecot.conf" or "anywhere in /etc/dovecot/conf.d/90-plugin.conf"), and do I need to take any other action? Actually, the folder I should like spam to go to is ~/Maildir/.Spam/cur/ - should I modify the above script? If these queries are anwered clearly in some dovecot documentation, please point me to that. -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

[Dovecot] dsync-local crashes due to assertion failures
by Fabian Groffen 30 Dec '13

30 Dec '13

Hi, I have two servers that share nothing, running dovecot version 2.2.9. The first server hosts the original mail base, which I want to sync using dovecot to the second server. With some trial and error I managed to get synchronisation running using tcp sockets. Now for some accounts I see dsync-local crashing on the server that has the original mail base (which is still the only of the two that receives new mail).

Any ideas on what I can do here? Both servers are configured to use maildir storage. Thanks, Fabian -- Fabian Groffen Gentoo on a different level

[Dovecot] pop3 rate limit
by Christian Rößner 30 Dec '13

30 Dec '13

Hi, we have customers with Exchange servers that are polling for new mail every minute with dozens of pop3 accounts. I am looking for a mechanism to rate limit this per user. So what I am looking for is a way to block users from polling, if a user asks for new mail more than every 5 minutes (for example). Is this possible? Can this be achieved within Dovecot or does it need external scripting? (I thought about fail2ban, but also want IPv6 support) Thanks in advance -Christian Rößner -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Axel von der Ohe, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein

[Dovecot] Sieve's spamtest always returns 0
by martin f krafft 28 Dec '13

28 Dec '13

I am a bit at a loss here with Sieve (pigeonhole) and the spamtest extension. I am using Dovecot 2.1.7 (backported to Debian squeeze), which comes with Pigeonhole 0.3.0. Messages are scanned with SpamAssassin, which adds a header like X-Spam-Status: Yes, score=84.6 required=5.0 tests=… and so I configured spamtest in conf.d/90-plugin.conf like so: sieve_spamtest_status_type = score sieve_spamtest_status_header = X-Spam-Status: [^,]*, score=(-?[[:digit:]]+\.[[:digit:]]).* sieve_spamtest_max_header = X-Spam-Status: [^,]*, score=[^[:space:]]+ required=(-?[[:digit:]]+\.[[:digit:]]).* I tested those regular expressions with sed -r, e.g. % sed -rne "s@^X-Spam-Status: [^,]*, score=-?[[:digit:]]+\.[[:digit:]] required=(-?[[:digit:]]+\.[[:digit:]]).*@\1@p" mailfile 5.0 and they work. Unfortunately, in sieve scripts, the spamtest value is always 0, which is indicative of the spamtest "not having run", which in this case I assume means that the regular expression didn't match. Am I right in assuming that the matching happens at the time of evaluation, and so adding the headers using vnd.dovecot.filter just before works? Or does the spamtest matching happen before the sieve scripts are executed? Can you see any other reason why spamtest always yields a value of 0?

[Dovecot] Dovecot 'Submission' service?

I do recall this being discussed, but I can't remember if it is actually in a working state now or not. According to the wiki, it is a work in progress: http://wiki2.dovecot.org/Roadmap?highlight=%28submission%29 So - is it in a functional state yet? Thanks, -- Best regards, */Charless/***

[Dovecot] Using DSync to convert from maildir to m/sdbox during migration of mail to new server
by Charles Marcus 27 Dec '13

27 Dec '13

Ok, now to work out the precise method (config for the target server and dsync command) to use to perform the migration from the old server to the new one, converting to dbox (s or m, depending on how the other thread discussing this turns out). I'll update the old server to 2.2.10 tomorrow morning so they're both at the same version. So, assuming both servers are running 2.2.10, with OldServer: mail_location = maildir:~/:INDEX=MEMORY and NewServer: mail_location = sdbox:~/sdbox or mail_location = mdbox:~/mdbox After reading and re-reading: http://wiki2.dovecot.org/Tools/Dsync I'm not so sure... First problem - apparently it can only be used one user at a time? And - do you have to actually know the users password too? If so, then this probably isn't going to be easier, and maybe even harder than just rsyncing everything, then slowly converting each user one at a time. -- Best regards, */Charles/*

[Dovecot] Migrating from Maildir to dbox+SIS... sdbox or mdbox?
by Charles Marcus 27 Dec '13

27 Dec '13

Ok... Now that I've got the niggling issues resolved, on to bigger and better things. I want to convert everyone from Maildir to dbox and enable SIS (our users use a lot of large attachments), and after some reading/googling, I think it may be better to use dsync instead of rsync for the actual migration after all since it will do this at the same time as the syncing. If I'm not mistaken, once I've figured out the correct syntax for the command, I should be able to do the conversion and migration at the same time. So, that is what I want to do, but I still have to choose between sdbox and mdbox. I tend to feel a little safer with sdbox, just because it seems more stable - and I like the idea that if a file gets corrupted somehow, then it is only that one mail that may potentially be lost, but if mdbox indexes get corrupted, you are guaranteed to lose messages (maybe a lot)... But I also really like the idea of an order of magnitude fewer actual files (would make rsync based backups much faster, etc). Timo - the last comments I was able to find from you were back in 2011... would you mind commenting on the current stated of dbox - especially mdbox, as far as reliability goes? The 'scary warnings' about how important the index files are ... well ... scares me... ;) I know there were definitely some issues with mdbox a few years ago - I found the old thread from 2011, but nothing substantial since, so... So... are there any people here, especially larger installs, using mdbox? sdbox? I'd especially be interested in hearing from anyone who has used both, and picked one over the other, and their reasons for doing so. Thanks, -- Best regards, */Charles/*

[Dovecot] Enabling SIS (single instance storage)
by Charles Marcus 27 Dec '13

27 Dec '13

Ok, didn't find much on this... The bottom of /etc/dovecot/conf.d/10-mail.conf has the following settings: #mail_attachment_dir = #mail_attachment_min_size = 128k #mail_attachment_fs = sis posix #mail_attachment_hash = %{sha1} all of which are apparently the defaults according to doveconf -d output - so no need to set them explicitly, unless I want to change them, right? So, enable the first one - but - the comments don't say anything about supporting variables. I'm assuming you can, otherwise all attachments for all domains would be in a single directory, which some admins might not like (I wouldn't)... so hopefully I can just set it to this: mail_attachment_dir = /var/vmail/%d/.attachments So how does this work during conversion? Users still on maildir simply don't engage it? But as users are converted to dbox, all attachments are de-duped, and then new mails coming in with attachments (for converted users) are de-duped at delivery? The wiki could do with a bit more on enabling and implementing it, especially what to expect when enabling it for the first time on a production system and what to expect along the way when converting existing users... -- Best regards, */Charles/*

[Dovecot] mail_location, user 'home', questions
by Charles Marcus 27 Dec '13

27 Dec '13

Hi all, Ok, another question... I always like changes to the default settings whenever possible (KISS principle)... So, according to the dovecot wiki, the default location for a maildir setup is: mail_location = maildir:~/Maildir However, when I first tried to access mail on the new box, something wasn't right, and I ended up having to change this to: mail_location = maildir:~ to get mail to display correctly. The filesystem for a users maildir currently has everything (cur/new/tmp, and the individual folders) inside that users directory, ie: /var/vmail/example.com/user/ Do I need to change this so that everything is under a 'Maildir' subdirectroy inside the users directory, like: /var/vmail/example.com/user/Maildir/ ? Also, I'm aware that it is important that even virtual users have valid 'homes', but I'm confused as to where these are (or are supposed to be) by default. My sql query currently contains: user_query = \ SELECT CONCAT('/var/vmail/', maildir) AS home \ FROM mailbox WHERE username = '%u' iterate_query = SELECT username AS user FROM mailbox So... what exactly is this saying? That the users 'home' is '/var/vmail'? Or does it automatically append %d/%u? I'm specifically wondering if the intention for the defaults is for the users home to be: /var/vmail/example.com/user and the users maildirs to be in: /var/vmail/example.com/user/Maildir Would appreciate some clarification... It wouldn't be hard to mv all of the users maildirs to a Maildir subfolder after the sync, but I want to know for sure that that is what I should/need to do... Thanks, -- Best regards, */Charles/*

[Dovecot] Thunderbird message cache out of sync after repetitive rsyncs...
by Charles Marcus 27 Dec '13

27 Dec '13

Ok, hopefully there is a solution to this. I've been experimenting with multiple rsyncs in preparation for pulling the trigger on the mail server switch, but have a problem that I really want to fox before doing so. Apparently something causes Thunderbirds local message cache to get out of sync with dovecot after a sync. Here is the series of commands I'm running: 1. stop postfix, stop dovecot on new server 2. rsync -rltgovDHP --delete --exclude-from 'excludes.txt' /path/to/vmail/example.com/ /var/vmail/example.com/ 3. chown vmail:vmail /var/vmail 4. start dovecot, start postfix ls -al /var/vmail/example.com/user/cur shows all of the messages that should be there, and all perms are correct. Go to my account that is pointed to this mail server/account, and none of the new messages show up. Also, some messages are still showing up that shouldn't. I've tried compacting the folders, closing/relaunching Thunderbird, but nothing helps. The only way to get them to show up is to go to the local Thunderbird cache for the account, and delete the files associated with the folder having the problem. The problem is, ALL folders will have this problem, which means that everyone will need to delete ALL of their local cahced folders. This will be a major support problem. Anyone have any ideas? -- Best regards, */Charles/*

[Dovecot] Server Migration Attempt - new messages DELETED after secondary rsyncs
by Charles Marcus 27 Dec '13

27 Dec '13

Starting a new thread, as I've got a lot more details now... First, I know this may be (or is even likely) something weird happening with Thunderbird, but the bottom line is, I have to find a resolution or a workaround or something, or I will be unable to pull the trigger on the server migration. It is simply unacceptable to lose ANY mails doing this. Goal: migrate mailstore from old server to new server using rsync Thunderbird (24.2) is set up to access the new account for testing Problem: after rsync, ls shows new messages (11 for the 27th), but when Thunderbird accesses the maildir again after another rsync, MOST (but not all) of the new messages are deleted (only one for the 27th remains) Timo - I'd be happy to do anything necessary to track this down if you'll just tell me what you need... Note: if you are pretty confident that upgrading dovecot on the old server and using dsync to do the migration will solve the problem, obviously I'm willing to do that if there is no other choice, but... I hope you'll want to get to the bottom of this regardless, as, according to you and everything I've read, it should work without losing any emails... Ok, as to details... Source (ol/active server): dovecot 2.1.17, postfix virtual for delivery, vmail owned by postfix:postfix Note: using prefix=INBOX. courier compatibility namespace Target: dovecot 2.2.10, dovecot LDA, vmail owned by vmail:vmail, nothing being actively delivered (yet) Note: NOT using prefix=INBOX. courier compatiblity namespace Both doveconf -n outputs at end of this message *** Could the different namespaces, or differing dovecot versions cause this?

[Dovecot] v2.2.10 released
by Timo Sirainen 27 Dec '13

27 Dec '13

http://dovecot.org/releases/2.2/dovecot-2.2.10.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.10.tar.gz.sig I've been really busy the last few months, as I guess people in Dovecot mailing list have seen since I haven't been very responsive. There are at least some dsync bugs I haven't had time to look into yet. The busyness probably continues for a while more, but the next year is looking much better for me and for Dovecot in general. We're planning to hire a few more Dovecot coders at some point, so if you're interested send me an email. :) + auth: passdb/userdb dict rewrite to support much more complex setups. See doc/example-config/dovecot-dict-auth.conf.ext. The old settings will continue to work. + auth: Added userdb result_success/failure/tempfail and skip settings, similar to passdb's. See http://wiki2.dovecot.org/UserDatabase + imap: Implemented SETQUOTA command for admin user when quota_set is configured. See http://master.wiki2.dovecot.org/Quota/Configuration + quota: Support "*" and "?" wildcards in mailbox names in quota_rules + mysql: Added ssl_verify_server_cert=no|yes parameter. This currently defaults to "no" to make sure nothing breaks, but likely will become "yes" in Dovecot v2.3. + ldap: Added blocking=yes setting to use auth worker processes for ldap lookups. This is a workaround for now to be able to use multiple simultaneous LDAP connections. + pop3c+dsync performance improvements - quota-status: quota_grace was ignored - ldap: Fixed memory leak with auth_bind=yes and without auth_bind_userdn. - imap: Don't send HIGHESTMODSEQ anymore on SELECT/EXAMINE when CONDSTORE/QRESYNC has never before been enabled for the mailbox. - imap: Fixes to handling mailboxes without permanent modseqs. (When [NOMODSEQ] is returned by SELECT, mainly with in-memory indexes.) - imap: Various fixes to METADATA support. - stats plugin: Processes that only temporarily dropped privileges (e.g. indexer-worker) may have been logging errors about not being able to open /proc/self/io.

[Dovecot] obox_fs and Dropbox, someone uses it?

I purchased the license for the Dovecot Object Storage for Dropbox to test this functionality on a personal domain. Unfortunately I can not make it work, I create the token for my Dropbox account from here https://dropbox.dovecot.fi/ and setup in dovecot configuration. When I try to login with an user I found these errors in log file: ============ Dec 27 10:52:16 mail dovecot: imap-login: Login: user=<dovecot1(a)test.it>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=8844, secured, session=<xxCXDIHuTQB/AAAB> Dec 27 10:52:16 mail dovecot: metacache-worker(8839): Error: fs-dropbox: GET 1/metadata/sandbox/dovecot1(a)test.it/idx/?file_limit=25000 failed: 401 Unauthorized Dec 27 10:52:16 archiviomail dovecot: metacache-worker(8839): Error: Failed to iterate dovecot1(a)test.it/idx/: GET 1/metadata/sandbox/dovecot1(a)test.it/idx/?file_limit=25000 failed: 401 Unauthorized Dec 27 10:52:16 mail dovecot: imap(dovecot1(a)test.it): Error: user dovecot1(a)test.it: Initialization failed: Namespace '': obox: USER-REF: /var/run/dovecot/metacache returned failure Dec 27 10:52:16 mail dovecot: imap(dovecot1(a)test.it): Error: Invalid user settings.

[Dovecot] German Umlauts in folder name and sieve

Hi all, On the old/current dovecot server, I have disabled on disk indexes: mail_location = maildir:~/:INDEX=MEMORY On the new server, I removed the 'INDEX=MEMORY' part, and I now see some new index related files, but what I don't see is the main dovecot.index file... I only have: dovecot.index.cache and dovecot.index.log So... where is the main dovecot.index file? -- Best regards, */Charles/*

[Dovecot] SHA512-CRYPT scheme fails password verification

I have dovecot version 2.2.9 on Linux 3.11.0-14-generic x86_64 Ubuntu 13.10 and I get the same results on 32-bit Debian as well. Does anyone have idea what's wrong? Thanks in advance, Jouko Nikula

[Dovecot] Patch for Dovecot's quota policy daemon
by Peer Heinlein 24 Dec '13

24 Dec '13

Hi Timo, we wrote a simple Patch for the Dovecot quota policy daemon. If a user is over quota, I prefer blocking the user sending e-mails, so I need a policy daemon, that's able to use the envelope or sasl sender as lookup key. I'd be happy if that patch can become part of the normale Dovecot releases. Peer -------- Original-Nachricht -------- Betreff: Re: Fwd: Quota-Patch Datum: Wed, 11 Dec 2013 17:33:45 +0100 Von: Stephan Seitz <s.seitz(a)heinlein-support.de> Organisation: Heinlein Support GmbH An: Peer Heinlein <p.heinlein(a)heinlein-support.de> Parameter r Code ENUM QUOTA_MATCH_RECIPIENT Stringmatch recipient= ${recipient} This macro expands to the complete recipient address.

[Dovecot] Eliminate legacy INBOX namespace - how?
by Charles Marcus 24 Dec '13

24 Dec '13

Hi all, Our mailstore was converted from a Courier-IMAP system last year, but I am planning a migration to a shiny new VM, and would really like to clean things up and do away with the legacy INBOX namespace. My goal is to simplify IMAP client setup - no special 'INBOX' namespace needed, they just enter the server info and credentials. Also important because I will be rolling out SOGo, which has a nice web interface, and I want the mailstore to be as close to default dovecot settings as possible - although I do plan on converting from maildir to mdbox when I do the conversion I also don't want other folders to show up as subfolders of the Inbox in IMAP clients, they should all show up on the same level as the Inbox. I've read http://wiki2.dovecot.org/Migration/Courier, but I don't see anything about how to eliminate this stupid legacy INBOX. namespace, so that new IMAP clients won't show all folders as subfolders of the INBOX unless/until they add the INBOX namespace prefix in the advanced settings. I've also been reading http://wiki2.dovecot.org/Namespaces, but I'm still confused as to how to go about this. Currently I have: 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 = INBOX. separator = . } The wiki recommends avoiding the 'alternative' of having two different namespaces, so I don't want to do that. Also - it would be ok if existing clients had temporary issues displaying folders properly until the INBOX prefix was removed (I would give everyone plenty of advance warning). Anyone ever done this before? Any suggestions Timo? Note: I am planning a migration to a new mail server (VM), so could make any filesystem layout changes when I do this if necessary. Thanks, -- Best regards, */Charles/*

[Dovecot] Is the users password available from a mail_filter?
by martijn.list 23 Dec '13

23 Dec '13

Hi, I'm working on a Dovecot encryption module which uses the mail filter plugin to encrypt/decrypt the message "on the fly". I was wondering whether it is possible to access the password (or a hashed password) of the user. It seems that only the user (using the %u parameter) is available to the mail_filter plugin. Any idea how to get hold of the (possibly hashed) password? Kind regards, Martijn Brinkers

Hi I have strange situation with one of mailboxes in mdbox format. Some messages are duplicated, not all. I am sure that is not sieve or another mail client issue, because access is via roundcube without sieve plugin.

[Dovecot] Horde + dovecot metadata support
by Andreas Schulze 23 Dec '13

23 Dec '13

Hello, Horde (http://horde.org) has the ability to store its preferences direct into a users imap mailbox using imap metadata extension. There are two implementations of the imap extension. 1. a dovecot plugin: http://hg.dovecot.org/dovecot-metadata-plugin 2. dovecot itself: http://www.dovecot.org/list/dovecot/2013-November/093243.html I setup Horde and dovecot-2.2.5 to use this extension and it works well using 1.) Now, with dovecot-2.2.9, the plugin fail to compile (unrelated problem on my side). So I tried 2.) But here I get a Horde-Error "Error in IMAP command GETMETADATA: Invalid arguments." I enables mail_debug but saw no helpfull logging. mail_attribute_dict = file:/tmp/%Lu/dovecot-attributes remote horde.testserver.ip/32 { imap_metadata = yes mail_debug = yes } Also I created directory /tmp/$my_login_id (mode 777) but dovecot also created no files. neither it logs anything about it. This is a sample imap session generated by horde: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN AUTH=LOGIN] Dovecot ready. 1 AUTHENTICATE PLAIN *** 1 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS SPECIAL-USE BINARY MOVE METADATA QUOTA] Logged in 2 NAMESPACE * NAMESPACE (("" "."))

Are there any hints or is the metadata extension just not fully implemented in dovecot?

[Dovecot] TLS SNI with Dovecot
by Michael Neurohr 23 Dec '13

Hi! I've been using Dovecot for one single Domain with SSL certificates. Now I would like to use Dovecot with several Domains and proper SSL certificates. I tried to setup TLS SNI but it does not work.

When trying to login via IMAP, I see the following lines in the log file: =================================================================== Dec 22 21:01:05 mx0 dovecot: imap-login: Warning: SSL alert: where=0x4004, ret=554: fatal bad certificate [151.236.5.22] Dec 22 21:01:05 mx0 dovecot: imap-login: Warning: SSL failed: where=0x2002: SSLv3 read client certificate A [151.236.5.22] Dec 22 21:01:05 mx0 dovecot: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=151.236.5.22, lip=151.38.7.25, TLS handshaking: SSL_accept() failed: error:14094412:SSL routines:SSL3_READ_BYTES:sslv3 alert bad certificate: SSL alert number 42, session=<Rg5EzyXutgCX7AaF> =================================================================== The actual Dovecot config is pasted below.

[Dovecot] Duplicated (but only for unread) messages after second rsync pass...
by Charles Marcus 22 Dec '13

22 Dec '13

Ok, I know I should probably be using dsync for this, but I'm more familiar with rsync, and didn't think this would be a problem. Here is what I am doing, and what is apparently happening (only done this once, but I'm guessing it will happen each time): rsync -avHP /mnt/vmail/example.com/user1/ /var/vmail/example.com/user1/ chown -R vmail:vmail /var/vmail/example.com Ok, so far so good, everything works fine accessing the mails (I'm using Thunderbird). Now I do another rsync, but this time I did the entire mailstore: rsync -avHP /mnt/vmail/example.com/ /var/vmail/example.com/ chown -R vmail:vmail /var/vmail/example.com Right after I started up dovecot again, I hot a bunch of these in the logs: 2013-12-22T09:52:51-05:00 newhost dovecot: imap(user1(a)example.com): Warning: Maildir /var/vmail/example.com/user1/: Expunged message reappeared, giving a new UID (old uid=45516, file=1387468268.Vfe02Ic1343fM845754.oldhost.sub.example.com:2,ST) 2013-12-22T09:52:51-05:00 newhost dovecot: imap(user1(a)example.com): Warning: Maildir /var/vmail/example.com/user1/: Expunged message reappeared, giving a new UID (old uid=45518, file=1387468645.Vfe02Ic73e0eM530539.oldhost.sub.example.com:2,ST) The problem is, it looks like every single message that was flagged as unread is now duplicated on the new system. Also - not that this is a problem, but all of the old messages have the fqdn of the old server in the individual email file names - oldhost.sub.example.com - while the new ones only have the local hostname (newhost) Did I do something wrong? Or is this going to be an unavoidable problem if I want to use rsync to do the final migration that using dsync would avoid? Thanks, -- Best regards, */Charles /*

[Dovecot] Dovecot proxying with LDAP - an example?
by Graham Leggett 22 Dec '13

22 Dec '13

Hi all, I have been struggling trying to understand the syntax to configure dovecot as a proxy against an LDAP server. As a single server dovecot works great. Now I want to add the "mailHost" attribute which, if present, should indicate the DNS name of the host that contains the person's mailbox. If the mailHost matches the local hostname, the mailbox should be served locally as it already does now. If the mailHost is not the local hostname, dovecot should proxy the request to the given server using SSL on port 993. The docs at http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy suggest that proxy_always is what I am looking for, but I cannot find any worked examples of how this might work. Has anyone attempted this before? What I have so far is this, but no proxying seems to take place: pass_attrs = mail=user,userPassword=password,\ mailMessageStore=userdb_mail,=proxy_always=y,mailHost=host,=ssl=yes Can anyone confirm? I am using dovecot v2.0.9 as provided out the box by RHEL6. Regards, Graham --

[Dovecot] 'unknown user' using dovecot LDA
by Charles Marcus 22 Dec '13

22 Dec '13

Ok, one more issue to resolve. The old server was still using the postfix/virtual for delivery, but the new one is using the dovecot LDA. Now, when an email generated locally by a cron job is delivered, this shows in the log: 2013-12-22T10:29:55-05:00 host postfix/pickup[31400]: C67FD90F676B2: uid=0 from=<newsrv+rkhunter(a)example.com> 2013-12-22T10:29:55-05:00 host postfix/cleanup[22349]: C67FD90F676B2: message-id=<20131222152955.C67FD90F676B2(a)smtp2.example.com> 2013-12-22T10:29:55-05:00 host postfix/qmgr[31401]: C67FD90F676B2: from=<newsrv+rkhunter(a)example.com>, size=1555, nrcpt=1 (queue active) 2013-12-22T10:29:55-05:00 host dovecot: auth-worker(22365): passwd(user1(a)example.com): unknown user 2013-12-22T10:29:55-05:00 host dovecot: lda(user1(a)example.com): msgid=<20131222152955.C67FD90F676B2(a)smtp2.example.com>: saved mail to INBOX 2013-12-22T10:29:55-05:00 host postfix/pipe[22361]: C67FD90F676B2: to=<user1+rkhunter-report(a)example.com>, relay=dovecot, delay=0.06, delays=0.02/0/0/0.04, dsn=2.0.0, status=sent (delivered via dovecot service) 2013-12-22T10:29:55-05:00 host postfix/qmgr[31401]: C67FD90F676B2: removed The mail was delivered (as the log also clearly shows), but what is with the 'unknown user'? I'm not sure how I can test my maps with dovecot, but testing with postfix shows: # postmap -q user1(a)example.com mysql:/etc/postfix/maps/mysql/vmm.cf example.com/user1/ Which is correct. And my dovecot-sql-conf.ext contains: driver = mysql connect = "host=localhost dbname=db_name user=dbuser password=password" default_pass_scheme = CRYPT password_query = \ SELECT username AS user, password \ FROM mailbox WHERE username = '%u' user_query = \ SELECT CONCAT('/var/vmail/', maildir) AS home \ FROM mailbox WHERE username = '%u' iterate_query = SELECT username AS user FROM mailbox I confirmed the db info is identical to what postfix is using. Oh - and in order to make sure that all usernames are lowercased, shouldn't I change '%u' above to '%Lu'? Appreciate any suggestions on where to go next... thanks -- Best regards, */Charles/*

[Dovecot] New server missing auth-worker entries in logs
by Charles Marcus 22 Dec '13

22 Dec '13

Hi all, Ok, I'm making progress on my new server, but there is an entry in the logs on the old/current server that is not showing p on the new one... lines like: dovecot: auth-worker(20284): mysql(localhost): Connected to database my_auth_db I've looked everywhere, compared settings, etc, and can't seem to find why I get this line on the old server and odn't on the new one. Anyone have a clue stick? Thanks

[Dovecot] File descriptor leak in sieve-extprograms
by Kirill A. Shutemov 21 Dec '13

21 Dec '13

I've tried to use sieve-filter for my inbox (~6000 messages). It failed after some work with this backtrace: sieve-filter(kas): Error: socketpair() failed: Too many open files sieve-filter(kas): Panic: file script-client-local.c: line 155 (script_client_local_disconnect): assertion failed: (pid >= 0) sieve-filter(kas): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x66a71) [0x7f020e717a71] -> /usr/lib/dovecot/libdovecot.so.0(default_fatal_handler+0x2a) [0x7f020e717ada] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7f020e6d32ee] -> /usr/lib/dovecot/modules/sieve/lib90_sieve_extprograms_plugin.so(+0x4baf) [0x7f020dae0baf] -> /usr/lib/dovecot/modules/sieve/lib90_sieve_extprograms_plugin.so(+0x58ca) [0x7f020dae18ca] -> /usr/lib/dovecot/modules/sieve/lib90_sieve_extprograms_plugin.so(script_client_fail+0x2f) [0x7f020dae199f] -> /usr/lib/dovecot/modules/sieve/lib90_sieve_extprograms_plugin.so(script_client_run+0xc4) [0x7f020dae1fd4] -> /usr/lib/dovecot/modules/sieve/lib90_sieve_extprograms_plugin.so(+0x6134) [0x7f020dae2134] -> /usr/lib/dovecot/libdovecot-sieve.so.0(sieve_result_execute+0x3ac) [0x7f020ecd1adc] -> /usr/lib/dovecot/libdovecot-sieve.so.0(sieve_execute+0x4a) [0x7f020ece05aa] -> /usr/bin/sieve-filter(main+0x6a9) [0x403b49] -> /usr/lib/libc.so.6(__libc_start_ma in+0xf5) [0x7f020e327bc5] -> /usr/bin/sieve-filter() [0x404111] The reason is file descriptor leak in "script client local". script_client_local_close_output() shutdowns write side of descriptor and sets sclient->fd_out to -1, but never closes the descriptor. I've tried to fix this by the patch below. Tests works fine, but sieve-filter crashed in other way: sieve-filter(kas): Panic: epoll_ctl(del, 13) failed: Bad file descriptor sieve-filter(kas): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x66a71) [0x7f0ed406fa71] -> /usr/lib/dovecot/libdovecot.so.0(default_fatal_handler+0x2a) [0x7f0ed406fada] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7f0ed402b2ee] -> /usr/lib/dovecot/libdovecot.so.0(+0x776f5) [0x7f0ed40806f5] -> /usr/lib/dovecot/libdovecot.so.0(+0x8009a) [0x7f0ed408909a] -> /usr/lib/dovecot/libdovecot.so.0(io_stream_unref+0x25) [0x7f0ed40764c5] -> /usr/lib/dovecot/libdovecot.so.0(o_stream_unref+0x26) [0x7f0ed4088136] -> /usr/lib/dovecot/libdovecot.so.0(+0x80e48) [0x7f0ed4089e48] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x27) [0x7f0ed407fa47] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xd7) [0x7f0ed40807d7] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7f0ed407f5e8] -> /usr/lib/dovecot/modules/sieve/lib90_sieve_extprograms_plugin.so(script_client_run+0x9c) [0x7f0ed343af8c] -> /usr/lib/dovecot/modules/sieve/lib90_sieve_extprograms_plugin.so(+0x6114) [0x 7f0ed343b114] -> /usr/lib/dovecot/libdovecot-sieve.so.0(sieve_result_execute+0x3ac) [0x7f0ed4629adc] -> /usr/lib/dovecot/libdovecot-sieve.so.0(sieve_execute+0x4a) [0x7f0ed46385aa] -> /usr/bin/sieve-filter(main+0x6a9) [0x403b49] -> /usr/lib/libc.so.6(__libc_start_main+0xf5) [0x7f0ed3c7fbc5] -> /usr/bin/sieve-filter() [0x404111] I failed to unfold this in a reasonable time.
