[Dovecot] Dovecot failing to parse some UTF-8 encoded attachment filenames, returning empty string instead
by Andrew Richards 30 Sep '11

30 Sep '11

Hi, I'm seeing a strange problem with some attachment filenames that are UTF-8 encoded. The problem seems to be related to spaces and/or unusual characters in filenames, like accented characters (or perhaps just to filenames if UTF-8 encoded; I've not explored that fully). These filenames are shown as empty strings in IMAP using Dovecot. I've attached a sample message that exhibits this problem, trimmed down to fairly bare essentials. By comparison I find that (for example) Courier happily returns the filename (still encoded). Although I suspect the problem lies within Dovecot, it may be an underlying Unicode or other component that's at the root of the problem. I can replicate this by putting the attached message in a mailbox (I'm using Maildir format mailboxes, so I just drop the raw file in Maildir/new and change the ownership of the file to match the mailbox owner). Then a pretend IMAP session to show the problem, $ telnet localhost 143 Trying ::1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready. 0 login some.one(a)test.domain password 0 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS] Logged in 0 select inbox * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 4 EXISTS * 0 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1316621730] UIDs valid * OK [UIDNEXT 8] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest 0 OK [READ-WRITE] Select completed. 0 fetch 4 body * 4 FETCH (BODY (("text" "html" ("charset" "iso-8859-15") NIL NIL "base64" 278 5)("application" "octet-stream" ("name" "") NIL NIL "base64" 18) "mixed")) 0 OK Fetch completed. 0 logout * BYE Logging out 0 OK Logout completed. Connection closed by foreign host. $ especially note the ("name" "") part showing a supposedly empty filename. I've observed this behaviour on the following versions of Dovecot, - 1.2.9 on Ubuntu 10.04LTS (pre-compiled version) - 1.2.17 on Fedora 13 (pre-compiled version) - 2.0.15 on Fedora 13 (from source) I don't think the Dovecot configuration is relevant, but I've put it below for good measure for the 2.0.15 setup. Any ideas on what might be causing this? Best regards, Andrew. # dovecot -n # 2.0.15: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.34.9-69.fc13.i686.PAE i686 Fedora release 13 (Goddard) auth_debug = yes default_login_user = nobody log_path = /var/log/dovecot.log passdb { args = /usr/local/bin/checkcdb driver = checkpassword } protocols = imap pop3 service auth { user = root } service imap-login { inet_listener imap { ssl = no } } service pop3-login { inet_listener pop3 { ssl = no } } ssl = no userdb { driver = prefetch }

[Dovecot] Virtual Folder configuration problem. [FIXED]
by Terry Carmen 29 Sep '11

29 Sep '11

Well, it took a ton of time and research, but I finally have a working Unread virtual mailbox on Dovecot 2.x on Centos 6.0. I have no idea if it's optimal or correct, but it works perfectly and doesn't raise any errors or warnings. Here's what I ended up with: dovecot.conf: Add the following: mail_plugins = $mail_plugins virtual namespace { type = private prefix = virtual. separator = . location = virtual:~/Maildir/virtual } 10-mail.conf: Add the following: # default namespace namespace { separator = . prefix = inbox = yes } 20-imap.conf: Add the following: protocol imap { mail_plugins = $mail_plugins virtual } 15-lda.conf: Add the following: protocol lda { mail_plugins = $mail_plugins virtual } Restart dovecot. Reload your mail client. Dovecot will create ~/Maildir/virtual cd ~/Maildir/virtual mkdir Unread Use your favorite editor and create a file named "dovecot-virtual" contaiing: # ~/Maildir/virtual/unseen/dovecot-virtual INBOX INBOX.* -INBOX.Trash unseen Save the file and restart your mail client. Go to "Subscriptions" in your mail client and subscribe to the Unseen folder. You should now have a virtual folder that contains all your unread mail, except for the contents of the Trash folder. Enjoy! -- Terry Carmen CNY Support, LLC https://www.cnysupport.com

[Dovecot] "Waiting for authentication process to respond" for invalid users with auth_dovecot
by Ibrahim Harrani 29 Sep '11

Hi, I am testing dovecot 2.0.13 and 2.0.14 with qmail-ldap and auth_dovecot patch. If i login to dovecot (pop3/imap) with correct user and password. no problem, I can login immediately. but if I try with nonexistant user, dovecot does not immediate answer, wait for a while and says "Waiting for authentication process to respond." auth_dovecot process remains working in the background.

[Dovecot] outlook 2007 very slow.
by Kui Zhang 29 Sep '11

29 Sep '11

Hello I have a user with 2500+ sub folders. Total mailboxes size is around 6G. (mdbox, dovecot 2:2.0.14) Syncing/Receiving appears to be slow, with outlook 2007. He does not want to switch to an alternative, due to various reasons. I did not find any error logs indicate issues. during idle, imap process appears to loop at adding inotify watches to all folders. I found outlook-idle in wiki, but it is obsolete. doveconf: Warning: Obsolete setting in /etc/dovecot/conf.d/20-imap.conf:55: imap_client_workarounds=outlook-idle is no longer necessary Any one else having similar issue? Anything else I should do to narrow down the issue? Thanks KuiZ

[Dovecot] Messages not deleted from mbox
by venom00 29 Sep '11

29 Sep '11

Hello, I've two accounts on my mail server, and from my client (Evolution) I've set up two configurations. If I dowload mail one account at a time everything works fine, but if I download both of them at the same time I'm not able to delete downloaded messages, so I download them twice, three times and counting to infinity. On th client side everything looks good: ----------------------------------------------------- LIST +OK 1 messages: 1 485 . UIDL +OK 1 000000704e57eebd . RETR 1 +OK 485 octets Message here... . DELE 1 +OK Marked to be deleted. QUIT +OK Logging out, messages deleted. ----------------------------------------------------- On the server side I've enabled debug logging but nothing relevant comes up, except sometimes an error: Panic: Message unexpectedly expunged from index Full log: http://pastebin.com/raw.php?i=bBizx9tm But most of the times there are no errors and simply the message is not deleted. I'm using mbox format in /var/spool/mail/%u. The dovecot user has read-write access to the folder (even because, as I said, if download an account at once everything works fine). I think it's about locking, I've tried several lock methods but always the same result and I can't see dead locks from lsof, fuser or ls (for dotlocks). Thanks in advance, venom00

[Dovecot] Dsync Removing Subscriptions Entries
by Asai 28 Sep '11

28 Sep '11

Greetings, In learning to get Dsync to work, I see a lot of this type of warning in the logs: dsync-remote(user(a)domain.org): Warning: Subscriptions file /vmail/domain/user/subscriptions: Removing invalid entry: INBOX/SOME folder When I ran a test this morning on the backed up emails on the remote server with Thunderbird, I did indeed see that many of the subscribed folders were not present in TB, although the directories and data were indeed present on the remote server. The subscriptions file on the remote server had the omissions which Dsync warned about. These maildir folders seem to work fine on the main server. Can someone help me to understand how to make the sync without omissions in the subscriptions file? -- *Asai* Global Change Multi-Media Internet Application Development IT and Networking Services 520-398-2542

[Dovecot] 2.0.14 IPC client_limit reached error

Hi Timo, Upgraded to 2.0.14 last night for the director-related features and I noticed an oddity in the logs: Sep 28 09:53:21 director2 dovecot: master: Warning: service(ipc): client_limit reached, client connections are being dropped Sep 28 09:53:56 director1 dovecot: master: Warning: service(ipc): client_limit reached, client connections are being dropped Sep 28 09:54:23 director2 dovecot: master: Warning: service(ipc): client_limit reached, client connections are being dropped Sep 28 09:55:07 director1 dovecot: master: Warning: service(ipc): client_limit reached, client connections are being dropped Sep 28 09:55:24 director2 dovecot: master: Warning: service(ipc): client_limit reached, client connections are being dropped Sep 28 09:56:08 director1 dovecot: master: Warning: service(ipc): client_limit reached, client connections are being dropped Sep 28 09:56:25 director2 dovecot: master: Warning: service(ipc): client_limit reached, client connections are being dropped Sep 28 09:57:10 director1 dovecot: master: Warning: service(ipc): client_limit reached, client connections are being dropped Sep 28 09:57:26 director2 dovecot: master: Warning: service(ipc): client_limit reached, client connections are being dropped These warnings are only being printed out by the directors. Both the directors and imap/pop3 servers have init scripts with the following ulimits set in the start sections: ulimit -s unlimited ulimit -n 30000 ulimit -u 30000 (We'd get alerts long before resource consumption became an issue) I've been watching the established imap/pop3 connection count on both directors for the past hour and a half and despite these warnings, those counts have grown continuously. The other weird thing is, according the configuration (attached), the ipc service has a client_limit of 0 by default, so we shouldn't be hitting a ceiling anyway, correct? So are these false warnings or something to be concerned about? -- Tom Pawlowski OIT-CSS System Administrator office: Hill 147 email: tompru(a)jla.rutgers.edu phone: (732) 445-2634

I'm attempting to create a virtual inbox that contains all unread messages from the user's Maildir.

[Dovecot] Create userdir on dovecot login --- solved
by Andreas Cieslak 27 Sep '11

27 Sep '11

Sorted out the problem, which was already solved in an older forum post of dovecot. In the file /usr/local/etc/dovecot/conf.d/auth-system.conf.ext I set Passdb { Driver = pam args = session=yes dovecot } Unfortunately this didnt work because when I log in with a user xy, the user dovecot became the owner of the userdir. When I modified the file /usr/local/etc/dovecot/conf.d/auth-system.conf.ext like this: Passdb { Driver = pam # args = session=yes dovecot } And gave anyone (for testing) the permission to write to home. That worked! At least put the ldap-users in a group and gave that group writing permissions to home. Finished! -----Ursprüngliche Nachricht----- Von: dovecot-bounces(a)dovecot.org [mailto:dovecot-bounces@dovecot.org] Im Auftrag von Andreas Cieslak Gesendet: Donnerstag, 22. September 2011 15:41 An: dovecot(a)dovecot.org Betreff: [Dovecot] Create userdir on dovecot login Hi List, I am trying to set up automated userdir-creation on login via squirrelmail or email-client with a dovecot backend. The users are first imported on an openldap directory on the same server as the dovecot runs on. Authentication on the dovecot mail system via pam_ldap works properly. Tried already to integrate some advices from the dovecot wiki like Passdb { Driver = pam args = session=yes dovecot } But the homedir creation works only when the user logs onto the machine. When I try to log in via Squirrel on the dovecot no homedir is created and there is following message in the logs: auth: Error: pam(cieslak,193.175.157.121): pam_open_session() failed: Permission denied I think its something about the user rights, but dont really know where to search for the needle Here is the config of my environment root@server:/home# dovecot -n # 2.0.13: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-686 i686 Debian 6.0.2 auth_debug = yes auth_mechanisms = login plain auth_verbose = yes first_valid_uid = 1000 hostname = server info_log_path = /var/log/dovecot-info last_valid_uid = 10000 listen = * log_path = /var/log/dovecot mail_access_groups = mail mail_debug = yes mail_full_filesystem_access = yes mail_location = maildir:~/Maildir mbox_write_locks = fcntl passdb { args = session=yes dovecot driver = pam } postmaster_address = mailaddress service auth-worker { group = shadow user = $default_internal_user } service auth { user = $default_internal_user } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } process_min_avail = 0 service_count = 0 vsz_limit = 256 M } service lmtp { unix_listener lmtp { mode = 0666 } } service pop3-login { inet_listener pop3s { port = 995 ssl = yes } } ssl_ca = </usr/local/etc/dovecot/ca ssl_cert = </usr/local/etc/dovecot/crt ssl_key = </usr/local/etc/dovecot/key userdb { driver = passwd } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } dovecot --version 2.0.13 The configuration of the pam module /etc/pam.d/dovecot looks like @include common-auth @include common-account @include common-session The common session has the line session required pam_mkhomedir.so skel=/etc/skel umask=0077 I would appreciate any hints.

[Dovecot] deliver agent and index/control files

27 Sep '11

Hi Timo and others, We use Dovecot in Kaunas University of Technology in Lithuania. For now our LDA is Postfix and POP/IMAP server is Dovecot. We would like to implement dovecot deliver as LDA. Everything is ok exept one small thing: deliver is creating dovecot.index.log in wrong place In dovecot config files we have: ... mail_location = maildir:/var/mail/%Ln:INDEX=/var/indexes/%Ln:CONTROL=/var/indexes/%Ln ... As you can see, mail and index/control files are in different partitions. and deliver log: deliver(nerijus.kislauskas(a)ktu.lt): maildir: data=/var/mail/nerkisl deliver(nerijus.kislauskas(a)ktu.lt): maildir++: root=/var/mail/nerkisl, index=, control=, inbox=/var/mail/nerkisl That is why dovecot.index.log is created in /var/mail/nerkisl, and not in /var/indexes/nerkisl. How can we fix this? -- Sincerely, Nerijus Kislauskas KTU ITPI, LitNET NOC Studentu g. 48a - 101, Kaunas tel.: (8~37) 30 06 45 mob. tel.: 8-614-93889 e-mail.: nerijus.kislauskas(a)ktu.lt

[Dovecot] Subscription File
by Carlos Mennens 26 Sep '11

26 Sep '11

I had a use lose 20 folders on their mail account. I was able to pull them back from a restore and dumped them all back on the server in her Maildir. The problem is she doesn't see them on her Thunderbird or Outlook client. I checked to make sure I put them back into the correct directory and I did as well as verify permissions aren't weird. I then noticed a file called 'subscriptions' in her Maildir directory. She appears to only be seeing folders that are listed in this 'subscriptions' file. My question is how do I update this file? If I delete it, will Dovecot re-generate the file with the correct subscription entries? I don't understand what to do but I'm hoping I don't have to edit the file by hand...that seems way too cumbersome.

[Dovecot] how to disable quota for second namespace?
by Udo Lembke 26 Sep '11

26 Sep '11

Hi all, I have a second namespace as archive, where no quota should be active (work with type = shared). But if I change the type to private the quota will allways count. My dovecot version is the 2.0.13. I have tried things like this: plugin { quota_rule = *:storage=500M quota_rule2 = Trash:storage=+100M quota_rule3 = Sent:storage=+50M quota_rule4 = ns=archiv/%u/:ignore } It's also doesn't work with "quota_rule4 = archiv/%u/:ignore" The namespace: namespace { type = private separator = / prefix = "archiv/%u/" location = maildir:/var/data/archiv/%d/%n:INDEX=/var/data/indexes/archiv/%u:LAYOUT=fs inbox = no hidden = no subscriptions = no list = yes } Even if I define the namespace for quota I see the quota-value also in the "root": plugin { quota = maildir:User quota quota2 = maildir:Archiv quota:ns=archiv/%u/ } doveadm quota get -u test(a)example.com Quota name Type Value Limit % User quota STORAGE 1587135 512000 309 User quota MESSAGE 13346 - 0 Archiv quota STORAGE 1359379 - 0 Archiv quota MESSAGE 10577 - 0 du -ks /var/data/mail/example.com/test 234364 /var/data/mail/example.com/test du -ks /var/data/archiv/example.com/test 1383792 /var/data/archiv/example.com/test Now is the big question, how can I reach such an output? doveadm quota get -u test(a)example.com Quota name Type Value Limit % User quota STORAGE 227756 512000 44 User quota MESSAGE 2769 - 0 Archiv quota STORAGE 1359379 - 0 Archiv quota MESSAGE 10577 - 0 I can't believe that's only possible with a shared namespace, or? Any hints are welcome. Best regards Udo

[Dovecot] "doveadm log reopen" don't reopen seperate lmtp log
by Henrik Larsson 25 Sep '11

25 Sep '11

Dear all I have setup separate pop3/imap log "/var/log/dovecot" and lmtp delivery log "/var/log/dovecot-deliver". After rotating logfiles, i run "doveadm log reopen". I see that my pop3/imap log "/var/log/dovecot" is used straight away, but my lmpt log "/var/log/dovecot-deliver" isn't used at first. After some time, usually a few minutes, logs are being written to this file anyway. But if I compare this to my maillog, it misses some deliveries just after the log rotation. Is there any problems with this configuration that should be corrected? --cut-- # doveconf -n # 2.0.15: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.2-STABLE amd64 auth_mechanisms = plain login digest-md5 cram-md5 first_valid_uid = 125 hostname = mail.larsson.it listen = * log_path = /var/log/dovecot mail_plugins = fts fts_squat zlib mail_privileged_group = postfix mail_temp_dir = /var/db/dovecot managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date namespace { inbox = yes location = prefix = separator = . type = private } namespace { hidden = yes inbox = no list = no location = prefix = INBOX. separator = . type = private } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { fts = squat fts_squat = partial=4 full=10 sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap pop3 lmtp sieve service auth-worker { user = $default_internal_user } service auth { unix_listener /home/mail/postfix/private/auth { group = postfix mode = 0666 user = postfix } } service lmtp { executable = lmtp -L unix_listener /home/mail/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } } ssl_cert = </etc/ssl/mail-chained.crt ssl_key = </etc/ssl/mail.key userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lmtp { log_path = /var/log/dovecot-deliver mail_plugins = fts fts_squat zlib sieve } protocol lda { mail_plugins = fts fts_squat zlib sieve } protocol imap { mail_plugins = fts fts_squat zlib imap_zlib } --cut-- Best regards Henrik Larsson

[Dovecot] dsync doubts
by Piotr NetExpert 24 Sep '11

24 Sep '11

Hi everyone, I want to backup mailboxes to another server. A usage information for dsync says "... <remote dsync command>". Does it mean I need dsync installed on the other server too? Now when I try to run dsync I receive: # dsync -v -D -u abc backup ssh user(a)other.server dsync(username): Debug: Effective uid=123, gid=123, home=/path/abc dsync(username): Debug: maildir++: root=/path/abc, index=, control=, inbox=/path/abc dsync-local(abc): Debug: Namespace : Using permissions from /path/abc: mode=0700 gid=-1 Password: server: not found dsync-local(abc): Error: read() from worker server failed: EOF What could be wrong? How can I check what it wants to do and cannot? I cannot find more information I need in a wiki page of dsync. -- pozdrawiam Piotr Szafarczyk http://www.netexpert.pl

[Dovecot] tiny doc bug report
by Jeff Rogers 23 Sep '11

23 Sep '11

First timer, I'm installing dovecot-2.0.15. I ran configure; make; sudo make install The INSTALL file then says: --- Rename configuration file: mv /usr/local/etc/dovecot-example.conf /usr/local/etc/dovecot.conf Read through, and make needed modifications. --- The example configuration file is not installed in that location. Presumably it is now installed as /usr/local/share/doc/dovecot/example-config/dovecot.conf Unless this path difference is a quirk of my local system, the INSTALL directions should be fixed to avoid confusion. Thanks, -J

[Dovecot] Using Dsync for Incremental Sync
by Asai 23 Sep '11

23 Sep '11

Greetings, We have about 26 GB of email which we're trying to sync nightly to a remote server, but what I just read from a post from Timo awhile back is that it's not possible because dsync relies on message GUIDs which aren't available in the IMAP protocol. It seems that this is still the case, is there anything on the horizon for this to change? -- *Asai* Global Change Multi-Media Internet Application Development IT and Networking Services 520-398-2542

[Dovecot] How to port this dovecot-1.x configuration file to dovecot-2.x
by forumer＠smartmobili.com 23 Sep '11

23 Sep '11

Hi, I am trying to move from dovecot-1.x to dovecot 2.1 but I have this error : Sep 23 16:04:13 lda: Error: userdb lookup: connect(/var/run/dovecot/auth-master) failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing +r perm: /var/run/dovecot/auth-master, dir owned by 0:0 mode=0755) and I dont' manage to find information about how to translate this old configuration part: socket listen { master { # Master socket provides access to userdb information. It's typically # used to give Dovecot's local delivery agent access to userdb so it # can find mailbox locations. path = /var/run/dovecot/auth-master mode = 0600 # Default user/group is the one who started dovecot-auth (root) user = vmail #group = } client { # The client socket is generally safe to export to everyone. Typical use # is to export it to your SMTP server so it can do SMTP AUTH lookups # using it. path = /var/run/dovecot/auth-client mode = 0660 } Thanks

[Dovecot] (2.1 recent:) fts_decoder
by Lutz Preßler 23 Sep '11

23 Sep '11

Hello again, test setup as in previous messages. With fts = lucene, I enabled the adapted decode2text.sh (at least I tried...) as suggested in the comment section. On dovecot-start /var/run/dovecot/decode2text socket is created with sufficiant permissions (rw for anybody), but decode2text.sh is not started (it's rx for anybody). When creating lucene indexes, I cannot see it executed either (and no attachment-only content is findable afterwards). No errors with mail_debug - if I change fts_decoder to a nonexistant value, that's logged. Lutz
