[Dovecot] IMAP flags not being committed properly?
by Janos Barbero 21 Feb '11

21 Feb '11

I'm afraid I can't give steps to reproduce this, but if someone's come across something like this, it might help me figure out what's going on. I run imapfilter/offlineimap to fetch mail from a gmail to a local maildir store, which I then access with alpine via dovecot (1.2.15). Here's the output of dovecot -n: # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian squeeze/sid ext3 log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot-info.log log_timestamp: %Y-%m-%d %H:%M:%S login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mail_location: maildir:/data/1/mail:LAYOUT=fs mbox_write_locks: fcntl dotlock mail_plugins: fts fts_squat auth default: passdb: driver: pam userdb: driver: passwd plugin: fts: squat Just recently, I went through a bunch of old unread messages, marking them as read (in alpine). When I selected all unseen messages in pine (;sn), 18 showed up. But the count was higher within Gmail even after an expunge and offlineimap sync. So I selected all seen messages (;s!n) and marked them all as seen (a*!n). This didn't take long (for a 30k message folder) but surprisingly enough came back with the notice that 15 messages were marked as seen, and sure enough, at the next offlineimap sync, flags were updated on 15 messages. So I didn't touch anything in gmail, everything went to the maildir through dovecot via alpine, and then back to gmail via offlineimap. Yet the select command obviously did not return all the matching messages. Anyone know what's going on? Thanks, Janos

[Dovecot] dsync problem: Error: Can't rename mailbox INBOX
by Jan Binder 20 Feb '11

20 Feb '11

Hi all, I'm running two debian machines with dovecot 2.0.9 autobuilds and would like to keep mails synchronized on both via dsync. Mails are kept in maildir on both sides. While syncing, dsync gives the following error: dsync-local(jan.binder): Error: Can't rename mailbox INBOX to INBOX_a432bf2eca595a4dba47000043b078f4: Renaming INBOX isn't supported. dsync-local(jan.binder): Error: Can't rename mailbox INBOX_e184273887675a4dcc5b00000c16d079 to INBOX: Target mailbox already exists Further diagnostic information: dsync command: dsync -D -v -f mirror ssh jan.binder(a)firefly.local dsync dovecot -n on firefly.local: # 2.0.9 (159605040ec0): /etc/dovecot/dovecot.conf # OS: Linux 2.6.37-trunk-686-bigmem i686 Debian wheezy/sid 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 passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap lmtp ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } dovecot -n on depth.local: # 2.0.9 (049a922c193c): /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian wheezy/sid 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 passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap lmtp ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } Should this usage of dsync work in principle?

[Dovecot] Maildir folders, separator = /, LAYOUT=fs (to support offlineimap)
by kkruzich 18 Feb '11

18 Feb '11

I use offlineimap to pull down some Gmail mail stores. With offlineimap I use sep = / and nothing more exotic. With dovecot I can see INBOX, messages, and messages in top level folders but not subfolders. I'm dealing with folder structure that looks like this: /opt/gmail/joe/Later /opt/gmail/joe/Tech/Projects /opt/gmail/joe/Tech/Projects/Fun /opt/gmail/joe/Tech/Projects/Failed /opt/gmail/joe/Tech/Projects/Planning The folder Later has cur, tmp, new and I can see messages. Projects is a container for subfolders Fun, Failed, Planning. I know Fun, Failed, Planning has messages but I'm not able to expand (via thunderbird) the folder Projects. I have this configured in dovecot.conf mail_location = maildir:/opt/gmail/joe:INBOX=/opt/gmail/joe/INBOX:LAYOUT=fs namespace private { separator = / list = yes } --- And this is what's getting logged... dovecot: Feb 18 07:26:39 Info: IMAP(joe): Namespace: type=private, prefix=, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes dovecot: Feb 18 07:26:39 Info: IMAP(joe): maildir: data=/opt/gmail/joe:INBOX=/opt/gmail/joe/INBOX:LAYOUT=fs dovecot: Feb 18 07:26:39 Info: IMAP(joe): fs: root=/opt/gmail/joe, index=, control=, inbox=/opt/gmail/joe/INBOX

[Dovecot] Upgrading Dovecot v1.0.10 -> v2.0.9
by Jackie Hunt 17 Feb '11

17 Feb '11

Hi all, OK, I admit it. I've seriously neglected our Dovecot installation. I installed version 1.0.10 in Jan 2008, and it has been a great workhorse since then. It has run like a champ, so it was ignored due to higher priority projects. But now it is time to get current with Dovecot, and I really need your help. We are using the mbox mailbox format. First so I want to upgrade to 2.0.9, since it looks like that is the latest version? It looks like development is still happening on the 1.x line, so do I need to get to the 2.x line? Any comments/suggestions/recommendations on that? I know there are major changes from 1.x -> 2.x.. Also, do I need to go through incremental upgrades? I'm guessing changes have been made to the index files and the dovecot configuration. Do those need to be done in steps, or can I made a major leap forward? I'd appreciate any input on this project. I need to start planning. Thanks so much! Jackie

[Dovecot] Problem with messages with long lines
by ZMA - Emiliano Mariño 17 Feb '11

17 Feb '11

Hello dear mailing list readers, Recently I am experimenting a problem trying to retrieve messages over a POP3 protocol. Everything goes right until the POP3 client tries to retrieve a message that contains one or more long lines lines as long as 3000 characters or even more. The client (Outlook 2003 and 2007) stops on that message until timeout. I have opened a connection manually to see what happens, and when I issue the RETR command on one of these messages, dovecot informs the message size and then nothing else. No message sending. Any other message works fine; I get the message size and next the message itself. I have upgraded to version 2.0.1 but I still get the same behavior. No error is reported on the server side. Logs indicate that everything is just fine. Any advice on how to solve this would be very appreciated.

[Dovecot] Dovecot + Exim + Maildir quota problem
by Matteo Tinazzi 17 Feb '11

17 Feb '11

Hi all i'm a new user of this list, i got a server with DirectAdmin which has exim as MUA, dovecot as POP/IMAP server, recently i added the quota to exim and pointed the maildirsize file in the same location if the dovecot's one so both services can interact with it. This has been done to let exim update the quotas while doing localdelivery while dovecot can show quotas through roundcube and update them when users delete mails. The issue that i noticed is that some users get wrong quota informations... after a little investigation i think it could be a concurrent access to this file so dovecot tries to remove the deleted mails fomr maildirsize and exim tries to put new ones inside. In a specific case i got a user with a quota of 50M seeing that 75% of his quota filled while the real weight of the mail files is about 4% ... any help would be very appreciated

[Dovecot] Dovecot 2.0.9/1.2.11: crash in driver-pgsql.c
by dovecot＠excellency.fr 17 Feb '11

17 Feb '11

Hello, I finally took time to isolate and reproduce a long time Dovecot crash that is bugging me since at least Dovecot 1.0.x. It's still there in Dovecot 2.0.9, which I just tested. Here is the backtrace from my logs: Feb 16 16:56:57 dovecot: auth: Error: pgsql: Query timed out, aborting Feb 16 17:25:16 dovecot: auth: Panic: file driver-pgsql.c: line 349 (result_finish): assertion failed: (db->io == NULL) Feb 16 17:25:16 dovecot: auth: Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0 [0x7fdbfe6d4272] -> /usr/lib/dovecot/libdovecot.so.0 [0x7fdbfe6d42d6] -> /usr/lib/dovecot/libdovecot.so.0(i_error+0) [0x7fdbfe6d46c8] -> dovecot/auth [0x42f555] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handle_timeouts+0xdd) [0x7fdbfe6df9bd] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x5e) [0x7fdbfe6e05be] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x28) [0x7fdbfe6df618] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7fdbfe6cd883] -> dovecot/auth(main+0x2d4) [0x419474] -> /lib/libc.so.6(__libc_start_main+0xe6) [0x7fdbfc4f91a6] -> dovecot/auth [0x40da09] Feb 16 17:26:35 dovecot: master: Error: service(auth): child 140263 killed with signal 6 (core not dumped) Both my userdb and passdb use a PostgreSQL database.

I can easily reproduce it by launching Dovecot with my host being up, and then null routing its IP address (to simulate an outage): route add -host 10.0.0.2 reject (10.0.0.2 being the IP address of the PostgreSQL host.) >From that point, if I try to authenticate (using a POP3 connection, for instance), dovecot-auth will crash one or two minutes later. In Dovecot 2.0.9, despite the crash, authentication will resume once the PostgreSQL is back up (which can be simulated with: route delete -host 10.0.0.2 reject).

[Dovecot] Cannot subscribe to shared folders
by Lukas Haase 17 Feb '11

17 Feb '11

Hi, I am unable to subscribe to shared folders with Thunderbird although everything seems to be correct (dovecot 1.2). What does not work? I click "Subscribe..." in Thunderbird. The shared mailboxes are listed, all with [ ] (no checkbox). Therefore I mark them [x], click "subscribe" and "OK". However, the folders do not appear in the folder tree. Furthermore, when I again click "Subscribe..." the folders do NOT have the mark [x] any more. This happens on different computers with *new* profiles. My configuration is the following (maybe that is the problem?!): namespace private { separator = . prefix =. inbox = no list = no hidden = yes location = maildir:~/Maildir-root subscriptions = yes } namespace private { separator = . prefix = INBOX. inbox = yes subscriptions = yes } namespace public { separator = . prefix = Shared. location = maildir:/var/mail/shared:INDEX=~/Maildir/shared:LAYOUT=fs subscriptions = no } The folder /var/mail/shared has appropriate permissions/form: * Owner: $user:mailuser (all users are member of "mailuser") * All files 0660, all folders 0770 * There exists a dovecot-shared in every folder * There exists a dovecot-acl in each folder where each user has the permissions "lrwstie" I switched on "mail_debug = yes" but no messages. However, the file ~/Maildir-root/subscriptions contains the subscribed folders: Shared.Group1 Shared.Group2 Shared.Group1/Test Furthermore, I switched on rawlog. Everything seems to be OK as well: .in-file: 2 subscribe "Shared.Group1" 3 lsub "" "INBOX.*" 5 lsub "" "Shared.*" 6 list "" "INBOX" .out-file: 2 OK Subscribe completed. [...] I am pretty sure it already worked. But it stopped working. Does anybody have a hint what could be the problem? Regards, Luke

[Dovecot] Some questions about mdbox
by Maria Arrea 16 Feb '11

16 Feb '11

Hello I am starting testing with dovecot 2.0.9. In my //etc/dovecot/dovecot.conf/ I have the following line: /mail_location = mdbox:/mydomain.org/%2.26Hn/%2.200Hn/%n:INDEX=/mydomain.org/indexes/%2.26Hn… These are my questions (a long mail): *1º How should I restore from backup with mdbox & separate indexes?* I have read in dovecot list archive about restoring the full user mailbox to a temp location and then run something like: /doveadm import mdbox:/tmp/restored_mailbox/ "" savedsince 2011-01-01 / In my schema indexes and mail stores are in separated paths. What (and where!) should I copy to the temp location and how do I restore it? *2º Disaster recovery: indexes & mail store mismatch* When creating backups, indexes and mail store are in different paths. My backup takes several hours, so indexes are copied BEFORE mail stores. Is the backup consistent? What would happens if I lose indexes? Can I still recover the messages? Reading the doc it seems I would lose all the message flags and all the messages would be in INBOX, is this right? *3º Performance tuning with mdbox* I have read in dovecot archive about using mdbox_rotate_size & mdbox_rotate_interval to balance between a lot of smaill files (like Maildir) or really big files (a "variant" of mbox). I have tested with a big vaule of mdbox_rotate_size (100 MB) and is a complete disaster for backup:if a user delete a message, then a nightly cronjob purges the mailbox (refcount=0) a new mdbox .m file is created!. So deleting a 1 k message from the mailbox of an user is a new 99 MB file to backup. Any hint about this? I am also using ext4 (rw,noatime,nodiratime,commit=15,data=writeback) and I have read about mdbox_preallocate_space. I will try it, any hint about this setup? This is not still in production, so I have no idea about IOPs and user concurrency, but I have several thousand users. *4º Compression with mdbox* I am reading about compression in mdbox (zlib/bzlib).

Re: [Dovecot] Some questions about mdbox
by Maria Arrea 16 Feb '11

Hello everybody I have found that with bzip compression level 6 I have a better balance between compression and decompression speed with dovecot+mdbox, but still too slow compared with zlib. Does anybody have any other hint about my original questions (see below) Regards Maria Arrea ----- Original Message ----- From: Maria Arrea Sent: 02/15/11 09:16 PM To: dovecot(a)dovecot.org Subject: [Dovecot] Some questions about mdbox Hello I am starting testing with dovecot 2.0.9. In my //etc/dovecot/dovecot.conf/ I have the following line: /mail_location = mdbox:/mydomain.org/%2.26Hn/%2.200Hn/%n:INDEX=/mydomain.org/indexes/%2.26Hn… These are my questions (a long mail): *1º How should I restore from backup with mdbox & separate indexes?* I have read in dovecot list archive about restoring the full user mailbox to a temp location and then run something like: /doveadm import mdbox:/tmp/restored_mailbox/ "" savedsince 2011-01-01 / In my schema indexes and mail stores are in separated paths. What (and where!) should I copy to the temp location and how do I restore it? *2º Disaster recovery: indexes & mail store mismatch* When creating backups, indexes and mail store are in different paths. My backup takes several hours, so indexes are copied BEFORE mail stores. Is the backup consistent? What would happens if I lose indexes? Can I still recover the messages? Reading the doc it seems I would lose all the message flags and all the messages would be in INBOX, is this right? *3º Performance tuning with mdbox* I have read in dovecot archive about using mdbox_rotate_size & mdbox_rotate_interval to balance between a lot of smaill files (like Maildir) or really big files (a "variant" of mbox). I have tested with a big vaule of mdbox_rotate_size (100 MB) and is a complete disaster for backup:if a user delete a message, then a nightly cronjob purges the mailbox (refcount=0) a new mdbox .m file is created!. So deleting a 1 k message from the mailbox of an user is a new 99 MB file to backup. Any hint about this? I am also using ext4 (rw,noatime,nodiratime,commit=15,data=writeback) and I have read about mdbox_preallocate_space. I will try it, any hint about this setup? This is not still in production, so I have no idea about IOPs and user concurrency, but I have several thousand users. *4º Compression with mdbox* I am reading about compression in mdbox (zlib/bzlib). I am starting with zlib, has anyone experience with bzlib? How much load is bzlib against zlib and how much delay adds to user experience (and space savings vs zlib???) ? *5º Recover a message with refcount=0* Is there any way to recover a message with refcount=0 without using a backup? I am thinking about the following plan: /1º a user gets her mail via pop3 (or delete a message via imap and empties trash) 2º the message is still stored in my mail server, but has refcount=0 3º nightly backup is performed 4º nightly cronjob purges the mailbox (deleting messaged with refcount=0)/ Using this schema the backup is bigger, but If I can recover files with refcount=0 from backup we can give our users a safeguard against accidentaly deleted pop3 mail.

[Dovecot] Auth processes/login processes count
by Thomas Hummel 16 Feb '11

16 Feb '11

Hello Timo, I'm running dovecot-1.2.12/Maildir/LDAP-passdb/LDAP-prefetched-userdb and I'm experiencing "random" latency (which even seem to make squirrelmail timeout sometimes) at login without noticing particular load on the server. LDAP backends are running fine as far as I know so I was investigating maybe mistuned limits : Dovecot is configured (for ~3000 users) with . each login processed in its own process : #login_process_per_connection = yes #login_max_connections = 256 . counts as : #login_processes_count = 3 login_max_processes_count = 1024 auth default { [...] count = 5 } I've got several questions : 1) how can I count more than login_max_processes_count processes ? # ps aux | egrep -i '(pop3|imap)-login' | wc -l # 1031 2) could be my auth process count the bottleneck ? is there a rule of thumb to deduce it from the login process count ? 3) on dovecot login/master/auth design, is my understanding correct ? - dovecot-1.2.x : . passdb and userdb lookup are done by the auth process, on behalf of either the login process which wants to know if the client's password is correct or of the master process which wants to check if it was actually correct and which wants to have the userdb info. . client connection fd is sent to the master which creates the mail process and transfers the fd to it. - dovecot-2.x : . client connection fd does not go through the master anymore but through a socket in the login/ directory . it's the mail process which ask the auth process for the userdb lookup 4) with LDAP backend using {CRYPT} passwords dans with plaintext auth enabled in dovecot, is the clear password crypted before comparing it to the LDAP crypted password or does dovecot try to simply bind to LDAP with the clear password ?

[Dovecot] test emails did not arrive at SMTP server : after dovecot installation
by sunhux G 16 Feb '11

16 Feb '11

Just set up postfix & it's running on my RHES 4.2 box. Immediately after postfix is up, I test sending emails from a permitted domain (ahhh, on this postfix server's domain firewall, we even have a firewall rule which permits Tcp25 from those few sending domains' SMTP servers) using an email client to sender_id@[IP_address_of_the_postfix_server] & the /var/log/maillog on the postfix server indicated the email arrives at the postfix server (with some errors though) : # grep recipient_id /var/log/maillog* maillog:Feb 15 11:41:52 hostname postfix/smtpd[6891]: NOQUEUE: reject: RCPT from gate1.mds.com.sg[203.126.130.157]: 554 5.7.1 <recipient_id(a)[202.6.163.31]>: Relay access denied; from=<prvs=020cae8c4=recipient_id(a)mds.com.sg> to=<recipient_id(a)[202.6.163.31]> proto=ESMTP helo=<gate1.mds.com.sg> maillog:Feb 15 13:43:20 hostname sendmail[7688]: NOQUEUE: SYSERR(recipient_id): can not chdir(/var/spool/mqueue/): Permission denied Then I installed dovecot rpm on my RHES box : uninstall it as it's an old version & reinstall with a newer version & start up dovecot as well. I did not test sending to sender_id@domain_name at that time because the domain I purchased from a domain provider/registrar has yet to be registered in our ISP's DNS. Subsequently I registered the following A, MX & NS records with our ISP : A: myportaltech.com. IN A 202.6.163.31 A: smtp.myportaltech.com. IN A 202.6.163.31 PTR: 31.163.6.202.in-addr.arpa. IN PTR smtp.myportaltech.com. MX: myportaltech.com. IN MX 10 smtp.myportaltech.com. NS: myportaltech.com. IN NS ns1.businessexprezz.com. NS: myportaltech.com. IN NS ns2.businessexprezz.com. The above myportaltech is just a fictitious name of my domain but I can provide the actual domain name if needed. After the above records have been propagated to all other DNSes, I test sending email from the same permitted domain, this time using domain name & the email never arrives & I did not receive a 'bounced mail' notification too. Then I test sending from the same domain to recipient_id(a)[202.6.163.31] & this time round, the test email never show up in /var/log/maillog* anymore. The network/security guys confirmed that the firewall logs did not show any denied SMTP records. So how do I go about troubleshooting this? Is this a DNS record entries issue, firewall/network issue, related to dovecot or something within my postfix server? Thanks Sun

[Dovecot] Dovecot can't start with error pop3-login & imap-login not supported protocol family
by sunhux G 16 Feb '11

16 Feb '11

I've done the installation (rpm downloaded from the RHES4 link given by Oli below) but dovecot won't start, it gave the error pop3-login & imap-login not supported by protocol. I'm sure with a much older version (in my previous post) of dovecot, I'm able to start up dovecot & it did not give this error.

[Dovecot] [Off Topic] - Any backup solutions ?
by Spyros Tsiolis 16 Feb '11

16 Feb '11

Hello kind people, OK, I know this is not for this list; However, reading all these mails on the topic of filesystems, I thought that it's a good place to ask about backup software on linux. Here's what I have. It's an HP 230 Ultrium LTO 1 SCSI backup mechanism (tape streamer to be exact). I'm supposed to hook it up today with an adaptec AHA-2940 controller to a gigabyte mainboard running Ubuntu Server 10.04. Does anyone have a config close to this one ? What kind of software would you chaps recommend ? dd ? Bacula ?? Other ?? This mechanism is supposed to grab backups from the same machine running it (the tape streamer), which is an ubuntu server version 10.04 with three SATA disks and maybe some stuff remotely (through the local network that is), from a couple of windows 7 / windows xp machines. Also 100Gb on every tape is not going to be enough and it looks like I will have to swap tapes during the process. Thank you all for your time and patience, Best Regards, spyros ---- "I merely function as a channel that filters music through the chaos of noise" - Vangelis

[Dovecot] Recover a deleted message in MDBOX format ?
by Frank Bonnet 15 Feb '11

15 Feb '11

Hello Every night a backup of all mailboxes is performed to a NFS mounted partition All our mailboxes are now in MDBOX format. I wonder how it would be possible to recover one email accidentally deleted by a user ? It was easy in MBOX format to extract and save it using mutt ( as root ) from the backuped mbox then re-copy it to the user's mbox. Of course I should access to the backup mailboxes space using thunderbird but doing this I need to know every users's passwords, that is unacceptable. for security and privacy reasons. Let users access to the backup space is not possible of course. Is there a tool ? Thanks

[Dovecot] NoSQL Storage Backend
by Marten Lehmann 14 Feb '11

14 Feb '11

Hello, I found a posting on the mailing list from 2008 "Adding new storage backend to Dovecot" while searching for POP3 and IMAP servers, that allow to use a NoSQL backend rather than a traditional file system. The problem with traditional filesystems is, that they are very limited. You cannot easily extend it, even with RAID 10 all messages may be lost due to a RAID controller failure and just-in-time backups of a heavy loaded system with consistently changing messages folders are virtually impossible. Modern object stores like Scality, CouchDB or MongoDB can be very handy, as they easily allow to keep an arbitrary amount of copies of each message on different servers, you can simply add a storage node and new storage is immediately available and mailboxes aren't bound to a certain server any longer, but messages are evenly distributed across all storage nodes, thus distributing load as well. Since the original posting was dated 2008 I was in good hope, that someone worked on that already, but at least in dovecot-2.0.9/src/lib-storage I couldn't find anything relating to NoSQL message stores. Isn't this option of big interest for every bigger mailbox provider? How hard would it be to develop? Would it be possible to get this developed on a paid basis by the dovecot core team? Kind regards Marten

[Dovecot] SIS generating 2 different hashes for the same mail and attachment
by Nick Rosier 14 Feb '11

Hi, I've been testing SIS over the weekend as it seems to be a nifty feature. I don't have that many users and mailboxes but still...

[Dovecot] Can't connect to auth server
by Phill Edwards 13 Feb '11

13 Feb '11

I'm trying to phase out procmail and move to dovecot-sieve instead. It ain't proving easy. I'll describe my setup: - Centos 5.2 box with dovecot 1.1.4 and dovecot-sieve 1.1.6 from ATrpms. - A single user account is used to store all our email (the account is called maildb). - Getmail is being used to fetch the email from various ISP mailboxes. I want to deliver mail to different folders in maildb's Maildir/ depending on who the email is addressed to (the procmail recipes currently do that). - Getmail destination section looks like this: [destination] type = MDA_external path = /usr/libexec/dovecot/deliver arguments = ("-d", "maildb") allow_root_commands = true - When I run getmail I get this error in dovecot.log: deliver(maildb): May 04 22:15:26 Error: Can't connect to auth server at /var/run/dovecot/auth-master: No such file or directory It's true that I don't have a file called auth-master. I guess I should have but until I started this dovecot-sieve work it was never a problem. I have no idea what that file should look like. As I installed from binary RPMs I would have thought one would have come with the install. Can anyone help? Regards, Phill

[Dovecot] preserving \Recent when moving messages
by Mark Hedges 12 Feb '11

12 Feb '11

Is there any way to preserve \Recent, or am I out of luck? Some people have reported that my script which shuffles around expired or oversized mail also causes their clients to report it as already read. I guess those clients check \Recent instead of \Seen when they download. I wish I knew which clients. With Mail::IMAPClient I tried using move(), copy(), and migrate() but the result is the same-- once it looks at the source message, \Recent is gone. (I tried patching it where it greps out the \Recent flag before appending the messages, but that causes a silent error.) Directly appending to the destination folder does not help either, since I would lose any flags set by the user, and if I tried to preserve those, then I would lose the \Recent flag when I read through the destination folder to figure out which messages were which. RFC5301 says \Recent can never be set... but does its prohibition include the case of migrating mail, where the intent is to retain them intact? It would be nice if Dovecot offered a migration feature which would move a message from folder to folder without unsetting \Recent. Mark

[Dovecot] problem configuring deliver in LDAP environment.
by Andrea Borghi 12 Feb '11

12 Feb '11

hello I am using dovecot-1.2.15 in debian squeeze (packaged) and i have some difficulties migrating from an older installation tha is working perfectly. i have a transport defined in postfix to call deliver as follows: dovecotlda unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -s -e -f ${sender} -d ${recipient} with the auth-socket in dovecot.conf all ok and this in ldap-userdb.conf: user_attrs = vdHome=chroot,mailbox=mail=maildir:%$,quota=quota_rule=*:bytes=%$,otherPath=sieve you see, i have the base directory for the chroot for the entire mail system in ldap:vdHome as /home/vmail/domains and the actual location of the mailbox in maildir format in ldap:mailbox so i can have the actual complete path as /(vdHome)/(mailbox) This is running smoolthly, BUT the chroot environment with all the library dependencies is REALLY REALLY limiting because the huge number of files from the system i must put on the mail storeage (which is networked and used by more systems so i cannot put libraries and binaries there) What i am trying to do is leaving all the dovecot services running in chroot mode (as they do) but let deliver running in NORMAL (non-chroot mode) so i need to remove the chroot variable in userattr reply, and parametrize the mail location with the two ldap values. i am conscious that i can set up this as user_attrs = mailbox=mail=maildir:/home/vmail/domains/%$,quota=quota_rule=*:bytes=%$,otherPath=sieve but I WANT TO KEEP THE BASE DIR PARAMETRIZED to leave me the possibility to set the base dir in LDAP to goup the accounts on different mail storage system. So you know a method to substitute TWO ldap values in the mail parameter definition? Thank you Andrea

[Dovecot] Questions about dovecot-shared in 1.2 and inherit group membership from parent mailbox
by Lukas Haase 12 Feb '11

12 Feb '11

Hi, I read the Wiki about dovecot-shared a few times but it is not 100% clear to me (at least for 1.2). First, if I want shared keywords I *must* have a dovecot-shared. In this case, the permissions are not taken any longer from the parent folder (what is exactly this parent folder?) but from the dovecot-shared file. So in some sense dovecot-shared is always required (since everyone would like to share keywords). True? Second, is there only *one* dovecot-shared per namespace or per mailbox *under* a specific namespace? Or an arbitrary number (where the "last" is taken)? Where does dovecot-shared need to be placed? For example, if the location of the namespace points to /var/mail/shared and I have two mailboxes "group1" and "group2" inside. Does the dovecot-shared need to reside in /var/mail/shared or /var/mail/shared/group1 and /var/mail/shared/group2 (with LAYOUT=fs)? Is it possible? Third (and main) question: In /var/mail/shared I want to have a mailbox for each group. Each user is member of his respective groups (in terms of UNIX permissions *and* ACLs). The mailboxes are owned by their respective groups and if a user creates a subfolder inside it should surely have the same group assigned as the parent mailbox (not the namespace!). namespace public { separator = . prefix = Shared. location = maildir:/var/mail/shared:INDEX=~/Maildir/shared:LAYOUT=fs subscriptions = no } mail:~# ls -l -R /var/mail/shared/ /var/mail/shared/: total 12 drwxrwx--- 5 root group1 4096 Feb 9 11:53 Group1 drwxrwx--- 5 root group2 4096 Feb 9 12:27 Group2 -rw-r--r-- 1 root root 23 Feb 9 11:52 dovecot-acl -rw-rw-r-- 1 root root 0 Dec 15 2009 dovecot-shared /var/mail/shared/Group1: total 16 drwxrwx--- 2 root group1 4096 Feb 8 10:35 cur -rw-r--r-- 1 root group1 28 Feb 9 11:52 dovecot-acl -rw-rw-r-- 1 root group1 0 Dec 15 2009 dovecot-shared drwxrwx--- 2 root group1 4096 Dec 15 2009 new drwxrwx--- 2 root group1 4096 Feb 8 10:34 tmp /var/mail/shared/Group1/cur: total 0 /var/mail/shared/Group1/new: total 0 /var/mail/shared/Group1/tmp: total 0 /var/mail/shared/Group2: total 16 drwxrwx--- 2 root group2 4096 Feb 8 10:35 cur -rw-r--r-- 1 root group2 27 Feb 9 11:52 dovecot-acl -rw-rwS--- 1 root group2 0 Dec 15 2009 dovecot-shared drwxrwx--- 2 root group2 4096 Dec 15 2009 new drwxrwx--- 2 root group2 4096 Feb 8 10:34 tmp /var/mail/shared/Group2/cur: total 0 /var/mail/shared/Group2/new: total 0 /var/mail/shared/Group2/tmp: total 0 Again: *Inside* /var/mail/shared I want to create mailboxes for each group (Group1, Group2, ...). This is done only by the administrator. Therefore /var/mail/shared is owned by root. Each Group1, Group2, ... in turn is owned by group1, group2, ... I tried all combinations using dovecot-shared which came into my mind such that a subfolder of Group1 is owned by group1. However, either 1.) the subfolder is owned by the primary group of the creating user (group "users") or 2.) the group of /var/mail/shared/dovecot-shared or 3.) creation of the subfolder fails with dovecot: IMAP(user1): chown(/var/mail/shared/Group2/Test1, -1, 0(root)) failed: Operation not permitted (egid=100(users), group based on /var/mail/shared/dovecot-shared) dovecot: IMAP(user1): mkdir(/var/mail/shared/Group2/Test1/cur) failed: Operation not permitted Is this just not possible or do I get something wrong here?

[Dovecot] [Q] auth(default): plain(?, 11.111.206.99): Username contains disallowed character: 0x20
by JKL 11 Feb '11

Dear all, A new user with Microsoft Express is trying to use IMAP SSL port 993. However they cannot log in. Its only with them. The logs details the following: Feb 11 18:56:03 logout dovecot: auth(default): plain(?,11.111.206.99): Username contains disallowed character: 0x20 Feb 11 18:58:07 logout dovecot: imap-login: Disconnected (auth failed, 1 attempts): method=PLAIN, rip=11.111.206.99, lip=62.58.61.184, TLS: Disconnected I think that the 0x20 is a space. However the user states that they are using this format and that there is no space: user.name(a)test.com Does anyone know where I could start to look for this? Regards,S

[Dovecot] Domain blacklisting
by Thomas Hummel 11 Feb '11

11 Feb '11

Hello, I run dovecot-2/Maildir/LDAP user/passdb and would like to be able to deny acess to users who connect from certain domains/IP (google.com for instance since in that case they gave their credentials to a third party). My understanding is that I cannot use some negative form of "allow_nets". The only mechanism I can think of is tcp_wrappers. However, dovecot documentation mention it only in the dovecot-1 section. Does it work the same way with dovecot-2 ? Is it a bad idea (I'm thinking of the induced overhead) ? Can you see another way to blacklist (at dovecot application level) some sources ? Thanks -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] Separate access to different "folders" of the same mailbox?
by Alexander Chekalin 11 Feb '11

11 Feb '11

Hello Timo and everyone, I think on such an idea that may save me a bit of space and time: in my company we have a mailbox that holds a copy of every message that our SMTP processed. While it eats a lot of space, it saved us several times when, you may imaging, user "suddenly" deleted the most important message in his life and call our IT guys for help. The mailbox contains "folders" for each day (like 2011-02-10), which keeps mailings for that day only. Even with this, it is sometime hard to work with that "keep all" box (basically, it is slow as the size is huge). What I'd like to add is some kind of "virtual folders" (for each of our internal users) that list messages from and to his address. And I'd like to permit every user to see (that is, read only mode) only "his" such a virtual folder in our "keep all" box, so user can see his old messages on his own. Looks like 1) I need an ACL to limit user access to "their" folders and somehow hide other folders at all 2) Have such virtual folders work with huge ammount of mailings (kind of 300 Gb), separated in maybe 1000 folders (per days). I really afraid it will be slo-o-o-ow search, even with indexes (I mean, virtual folder that is defined as search over 1000 folders will be not that fast). The mailbox is maildir by nature. How can I archive these goals with smallest load possible, and if it is possible at all? Thank you, Alexander Chekalin

[Dovecot] xi.rename-it.nl/debian/ dovecot-2.0 sieve problem

11 Feb '11

Hi, i used to use deb http://xi.rename-it.nl/debian/ stable-auto/dovecot-2.0 main to update dovecot 1.2 with debian lenny. I used the convert script to change my configuration file. Everything works fine but sieve does not work anymore. There is no error in the logs but dovecot simply ignores any filter. I checked the documentation/configuration twice and had still no success. Maybe, this is a known/unknown bug or any suggestions? Best regards Martin Rozgonski

I'm still having issues with the combination of mdbox, sis, and zlib. Is anyone else using these without seeing any errors in the logs? -- Daniel

[Dovecot] multiple domains
by Sergio Moscoso 10 Feb '11

10 Feb '11

Anybody can help me with this issue. It's the right place to submit thios question, please help me. Actually we have configured a server (postfix,dovecot,mysql) with multiple domains, but the problem resides in that we don't want to login via POP3 using "user@domain" just using "user", because we'll migrate our actual platform (Qmail) to dovecot. Our users are logging to their mail boxes, using only user name. We want to ask if that's posible to use a function like a "vipmap" in qmail, that allow to map an IP address to a domain. We're using the dovecot 1.0.7, the configuration shows as follows: login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login first_valid_uid: 100 mail_location: maildir:~/Maildir/ mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh imap_client_workarounds(pop3): outlook-idle pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: username_format: %Lu passdb: driver: sql args: /etc/dovecot-mysql.conf userdb: driver: static args: uid=101 gid=102 home=/home/vmail/%d/%n We'll apreciate your response, 'cause we coulnd't find information about this issuet and we didn't to find any clue that shows how can realize it. Thank you in advance. Sergio Moscoso

Hello list, In my dovecot-ldap.ext I have: uris = ldaps://host1 ldaps://host2 ldaps://host2 Today host1 hangs and new connections can't be established with mail server. Connected users worked fine (auth_cache_size = 5 k auth_cache_ttl = 15 mins). At this time - host2 and host3 are working fine, but switching to them was not happen. Why ? In logs I got: Feb 09 10:20:36 imap-login: Error: Timeout waiting for handshake from auth server. my pid=29932, input bytes=0 Feb 09 10:20:36 imap-login: Error: Timeout waiting for handshake from auth server. my pid=29867, input bytes=0 Feb 09 10:20:37 imap-login: Error: auth: connect(login) failed: Resource temporarily unavailable Feb 09 10:20:37 imap-login: Error: auth: connect(login) failed: Resource temporarily unavailable Feb 09 10:20:39 imap-login: Error: Timeout waiting for handshake from auth server. my pid=29943, input bytes=0 Feb 09 10:20:40 imap-login: Error: auth: connect(login) failed: Resource temporarily unavailable I also tried to set: hosts = host1:636 host2:636 host3:636 But with above config error log fulls with messages: Feb 09 10:44:57 auth: Error: LDAP: Connection lost to LDAP server, reconnecting And none of servers accepted ldaps connection. Is someone has a success make ldaps fault tolerance ?
