I've checked my setup - the guest is not set to sync with the VMware host. NTP is running with local clock server commented out & 'tinker panic 0' set. It sounds like this is not a Dovecot issue so I'll stop posting to this list now and seek help elsewhere. What negative effects to Dovecot would I expect to see where the system clock is constantly changing?

[Dovecot] Check if a message has attachments
by Antoine Nguyen 14 Jan '11

14 Jan '11

Hi all, my question is not specific to Dovecot but to the IMAP protocol in general. I'm working on a web based software that provides a simple webmail ( http://modoboa.org/) I'm wondering what would an efficient way to detect if a message (or a group of messages) has attachments. I know it certainly consists in checking for specific MIME constructions but how to achieve that without fetching the whole body for each message? Thanks in advance, Antoine Nguyen

[Dovecot] Running two different versions of Dovecot (was: making folders unmovable)
by David Salisbury 14 Jan '11

14 Jan '11

OK, so I decided to go ahead and just upgrade to the latest 1 series Dovecot and see if that solves my ACL/config issues I've been having. (I tried compiling 2.0.9, but it errored out and I assume that's because it's a pretty old machine/compiler.) Anyway, 1.2.16 compiled fine, and I installed it in another location from the currently running 1.1 series install. I have this new install running (IMAP) on a non-standard port while I test it out, and it starts fine and all seems well. However, I'm wondering, is it OK to run it and have it look at the same Maildir mailboxes as the currently running 1.1 series install? Does that have the potential to mess with indexes or change anything in a bad way? (FWIW, I tried it briefly, and after changing the port number in and restarting my mail client [Thunderbird], it had trouble pulling up the mailbox I was trying to access.) David

Thanks, I've read through that document a couple of times now & I'm fairly sure my system 'ticks all the boxes' yet the warning messages continues. I can see no noticeable time discrepancy when I do periodic time checks from the command line comparing against another system's clock - certainly not 2 minute error margin Could this be a time mismatch between imap client & server?

[Dovecot] email addresses as usernames with Kerberos
by Peter Mogensen 14 Jan '11

14 Jan '11

Hi, I was trying out Kerberos authentication with som sample users for Dovecot and stumbled into this problem: The user names are of the form local-part@domain, so the Kerberos principal becomes "local-part\@domain@REALM". But it seems Dovecot (1.2.9) doesn't understand that syntax. Looking at the 2.0.8 sources I guess it's not supported. But isn't this a valid Kerberos principal? Is it a bug, or a missing feature or is there a special reason for not supporting it ? kind regards, Peter

Has anyone else encountered this message? Is it something to be concerned about? Thanks, Ian.

Re: [Dovecot] Making shared folders "unmovable"
by Dave 13 Jan '11

13 Jan '11

Well, I just noticed this in my logs after I re-loaded the latest Dovecot config I tried: Jan 13 15:09:45 mail dovecot: SIGHUP received - reloading configuration Jan 13 15:09:45 mail dovecot: read(imap dump-capability process) failed: Interrupted system call Jan 13 15:09:45 mail dovecot: Invalid configuration, keeping old one Jan 13 15:09:45 mail dovecot: child 2085 (unknown) returned error 82 (Internal logging error) It's apparently been doing this every time I've reloaded the config, so this is probably why none of my changes with the ACLs are working. :/ Any thoughts on what could be causing this kind of error?? Does that error just basically mean something's set wrong somewhere in dovecot.conf? David

The 3.x branch is rock solid. There have been no crashes (yet!) Would DRBD + GFS2 work better than NFS? While NFS is simple, I don't mind experimenting with DRBD and GFS2 is it means fewer problems?

[Dovecot] Denying authentication
by Romer Ventura 13 Jan '11

13 Jan '11

Hello, I've been running dovecot for over 3 years now and it works with no problems. I have it setup so that it authenticates users against Active Directory via LDAP and so far no problems. What I would like to know is if there is any way that I could deny access for users trying to access email via cellphones or email clients outside the company. I can close everything since there are a few users that need to get emails from outside the company via cell phone of email clients. I was thinking if there was a way to lets say create a group in AD named: "remote-email" that will allow connection and authentication from any network, any user not in that group will only be able to authenticate if the source is 192.168.xx.xx/24. Is this possible? Maybe not with Dovecot, but maybe someone else has any ideas..? Thanks -------- Romer Ventura

[Dovecot] Making shared folders "unmovable"
by Dave 13 Jan '11

13 Jan '11

I have set up an area of shared folders with Dovecot 1.2 that is accessed by several people (by way of one account, and everyone who logs in sees these same folders), and the only problem with this setup is that occasionally somebody moves one of the folders underneath another folder or somewhere else in the folder structure, and this sometimes disrupts some automatic procmail filters and the like. Is there a way to keep folders in a shared setup such as this "static" or "unmovable" so that the users can't disrupt the structure? Like, where the folder structure itself can't be changed, but new messages can still come in to the folders? David

[Dovecot] How do folk . . . Aggregate system mail from LAN machines?
by Ron Leach 12 Jan '11

12 Jan '11

List, good evening, Running Dovecot for external email, but not yet worked out how (best) to aggregate 'system' mail from other machines on the LAN. By system mail, I mean mails generated by the OS or by applications, and addressed to root, or 'some admin user', etc. Ideally, these would be seen by 'root' or 'some admin user' or whoever on our existing Dovecot/IMAP system. Our scale is not large, we only have 5 servers on the LAN doing various things. I wondered how other Dovecot users do this. I've thought of 3 possibilities: 1. Install Dovecot on each LAN machine, and use Fetchmail to retrieve the messages using POP so that local mail stores were emptied. 2. Perhaps, use a 'forwarding' mechanism of some sort on each LAN machine, but that would require an MTA on each LAN machine, would it not? 3. I wondered whether /etc/alias, mentioned in a recent post by Simone Caruso, might help though again, presumably, requiring an MTA on each LAN machine. What do you do? regards, Ron

[Dovecot] Question about lda & auth_socket_path
by Jahnke-Zumbusch, Dirk 12 Jan '11

12 Jan '11

Hi all, storing e-mails (using postfix) via dovecot-lda fails and I assume this is related with a auth_socket configuration problem. But I am at a dead end, so perhaps anybody has got a hint for me: This is dovecot-2.0.8 on Solaris 10: 10-auth.conf and its include: ----------------------------- ... userdb { driver = static args = uid=104 gid=104 home=/some/path/%u } Relevant parts of 10-mail.conf: --------------------------------- ... auth_socket_path = /var/run/dovecot/auth-userdb Relevant parts of 10-master.conf: --------------------------------- ...service auth { unix_listener auth-userdb { mode = 0644 user = vmail #group = } } service auth-worker { user = root } Relevant parts of 15-lda.conf: --------------------------------- ... protocol lda { # Space separated list of plugins to load (default is global mail_plugins). #mail_plugins = $mail_plugins } # ls -l /var/run/dovecot/auth-userdb srw-r--r-- 1 vmail root 0 Jan 12 15:49 /var/run/dovecot/auth-userdb Using dovecot-lda for mail delivery or doveadm for user inquirement fails: via debug_log_path: ------------------- Jan 12 16:04:14 auth: Debug: Loading modules from directory: /dovecot/code/dovecot-2.0.8/lib/dovecot/auth Jan 12 16:04:14 auth: Debug: passwd-file /store1/db/masterusers.passwd: Read 1 users Jan 12 16:04:14 auth: Debug: master in: USER 1 djahnke service=lda Jan 12 16:04:14 auth: Debug: password(djahnke): passdb doesn't support credential lookups Jan 12 16:04:14 auth: Debug: master out: FAIL 1 Jan 12 16:04:14 lda: Debug: auth input: via syslog: ----------- Jan 12 16:04:14 deliver1 dovecot: [ID 583609 local0.error] auth: Error: static(djahnke): passdb doesn't support lookups, can't verify user's existence Jan 12 16:04:14 deliver1 dovecot: [ID 583609 local0.error] lda: Error: user djahnke: Auth USER lookup failed Jan 12 16:04:14 deliver1 dovecot: [ID 583609 local0.crit] lda: Fatal: Internal error occurred. Refer to server log for more information. When I use "allow_all_users=yes" everything works fine, so I think somehow the communication with the socket fails. I cannot see what I have missed :-( Any suggestions what I should look for / configure ? Any help appreciated, cheers, Drik -- Dirk Jahnke-Zumbusch Deutsches Elektronen-Synchrotron DESY IT Information Fabrics Member of the Helmholtz Association D-22603 Hamburg Notkestrasse 85 / 22607 Hamburg T: +49-40-899.81760 F: +49-40-899.41760 dirk.jahnke-zumbusch(a)desy.de

[Dovecot] Dovecot fails after updating MySQL
by Jerry 12 Jan '11

[Dovecot] mail quota dovecot 1.2.15-3
by J4 12 Jan '11

12 Jan '11

Dear all, I am attempting to enforce quota with Dovecot 1.2.15-3 using LDA for deliver. I use smtp-source (postfix) to deliver large messages but the quota is never noticed. The webmail interface is Roundcube, and the admin is performed using Postfixadmin. I have not looked into the postfix portion for quota, yet. Is there something that I have missed from the configuration? (The contents of relevant the mysql tables are included) Best wishes, J. # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-cgmemcap-smack x86_64 Debian squeeze/sid ext4 log_timestamp: %Y-%m-%d %H:%M:%S ssl_listen: *:993 ssl: required ssl_cert_file: /etc/ssl/certs/smtpd.crt ssl_key_file: /etc/ssl/private/smtpd.key login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login first_valid_uid: 106 mail_privileged_group: mail mail_location: maildir:/var/vmail/%d/%u/ maildir_very_dirty_syncs: yes mbox_write_locks: fcntl dotlock mail_plugins: quota imap_quota lda: log_path: auth_socket_path: /var/run/dovecot/auth-master postmaster_address: postmaster(a)test.info mail_plugins: sieve quota auth default: mechanisms: plain login passdb: driver: pam passdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf userdb: driver: passwd userdb: driver: static args: uid=5000 gid=5000 home=/var/vmail/%d/%n allow_all_users=yes userdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail plugin: quota: dict:user::proxy::quotadict dict: quotadict: mysql:/etc/dovecot/dovecot-dict-quota.conf select * from mailbox; +--------------------------+------------------------------------+--------------+---------------------------+----------+------------+------------------+---------------------+---------------------+--------+ | username | password | name | maildir | quota | local_part | domain | created | modified | active | +--------------------------+------------------------------------+--------------+---------------------------+----------+------------+------------------+---------------------+---------------------+--------+ | 11(a)test.info | $1$abc111kdddjkfsdhfjksdhfj. | TEST | test.info/11/ | 1024000 | 11 | test.info | 2011-01-07 14:19:03 | 2011-01-12 11:34:32 | 1 | +--------------------------+------------------------------------+--------------+---------------------------+----------+------------+------------------+---------------------+---------------------+--------+ select * from quota; +-----------------------------+-----------+----------+ | username | bytes | messages | +-----------------------------+-----------+----------+ | 11(a)test.info | 173879747 | 5689 | quotadict = mysql:/etc/dovecot/dovecot-dict-quota.conf ## dovecot-dict-quota.conf connect = host=localhost dbname=mail user=mail password=fred 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 }

[Dovecot] Refilter Mailboxes via Sieve - Missing delivered-to header
by Dieter Knopf 12 Jan '11

12 Jan '11

Hello, i already read http://wiki.dovecot.org/HowTo/RefilterMail but it won't work here :( I have many old mails in my folders and need to refilter many of them. But there are many mails without a delivered-to-header. What can i do? Error: Configuration error: envelope_recipient specified header missing (delivered-to:1) Would be okay if getmail would just skip the mail, but it cancels. Not sure if there is any way around. This is the config: [retriever] type = MultidropIMAPSSLRetriever envelope_recipient = delivered-to:1 server = foo port = 993 username = foo password = foo mailboxes = ("INBOX.REFILTER",) move_on_delete = INBOX.trash [destination] type = MDA_external path = /usr/lib/dovecot/deliver arguments = ("-e", "-f", "%(sender)", "-d", "%(recipient)") user = vmail group = vmail [options] delete = true recieved = false delivered_to = false verbose = 2 I'm using virtual users, so i must use Multidrop. Thanks

[Dovecot] Connection queue full on my directors
by Jan-Frode Myklebust 11 Jan '11

11 Jan '11

I finally upgraded to v1.2.16 on my backend servers, with ldap instead of previously mysql, and put a couple of dovecot v2.0.8 directors in front of them (used haproxy previously). It seemed to work OK initially, but after a few hours we got bit by "Connection queue full" problems on the directors. So I now set default_process_limit=512 and also: service anvil { client_limit=1027 } since dovecot said that was now required. Things seems to be working, but I'm afraid default_process_limit=512 is too low: $ ps -ef|grep dovecot/pop3-login|wc -l 192 $ ps -ef|grep dovecot/imap-login|wc -l 472 so looks like I'm quite close to hitting this limit for my imap logins. We will eventually put up some webmail servers (using imapproxy to keep connections alive), that will be connecting over these directors. Then we will expect to have a lot more active imap sessions over these directors. Should we just keep increasing default_process_limit, or per service process_limit, and follow dovecots warnings about client_limits for auth/anvil.. or will we be getting into other problems like running out of file descriptors? Are there any max'es we should expect to run into ?

[Dovecot] Dovecot - AllowGroups option
by Jacob Neergaard Pedersen 11 Jan '11

11 Jan '11

Hi, I'm trying to control access to different services on an Debian server using /etc/group. So that a user I create for FTP usage doesn't fill up my server with IMAP folders or samba garbage. Services like proftpd have: "AllowGroup ftpgroup" sshd have "AllowGroups sshgroup" And samba have "valid users = @smbgroup" But I can't find the correct option in Dovecot (/etc/dovecot/dovecot.conf) Do anyone have the magic option or a workaround thats doesn't envolve maintaining seperate user databases and password? (I know its needed for samba but besides that) /Neergaard

[Dovecot] utility to copy/sync IMAP mailboxes
by Don Buchholz 11 Jan '11

11 Jan '11

Well, my Dovecot server (v2.0.8) is up and running, and now it's time to migrate mailboxes from the old mail server [Lotus Domino Release 5.0.8] running on Windows NT 4.0 [ancient -- been the mail server since Aug-2000]. I saw "dsync(1)" and thought my troubles were over. Only I can't figure out how to make it work with the NT/Domino server as a source for mailboxes. I guess dsync(1) works only in completely *nix environment. I've been trying the imapcopy.pl script from the IMAP Tools web page (http://www.athensfbc.com/imap_tools/) but it is having problems with Notes' choice of the backslash (\) character as a mailbox (namespace?) delimiter. Any suggestions for a stable, reliable (copy/duplicate/mirror/sync) tool that can do the job using only IMAP access? (No SSL support required.) Thanks in advance, - Don

[Dovecot] Max number of mail processes
by Patrick Nudo 11 Jan '11

11 Jan '11

Dovecot version 1.1.11. Error: Maximum number of mail processes exceeded (see max_mail_processes setting). I can't seem to get rid of these errors. I get batches of these errors about 4 or 5 times a day. I have a cron-job checking for the existence of this error and then I reboot dovecot when I see this error, but what is causing this error ? What I am reading on the Internet about this particular issue has not helped to resolve the issue. I would really like to know how many mail processes it thinks that it is using at any one instant in time. Is this possible ? Maybe then I can track the reason for the error.

[Dovecot] enforce STARTTLS on port 110 with POP3?
by Zhou, Yan 11 Jan '11

11 Jan '11

Hi there, We are using DoveCot 1.0.7. User will use POP3 or POP. We want to force user to securely send their credential and keep a secure connection between us and them. We can do TLS/SSL on port 995, or STARTTLS on port 110. The problem is that we have no way to enforce STARTTLS on 110, user can connect to DoveCot on port 110, sending user credential without STARTTLS (thus insecure). Reading DoveCot documentation does not sound it supports this. Here is what I got from documentation. Dovecot supports: * IMAP (including TLS/STARTTLS) * IMAP+SSL ("imaps") * POP3 (including TLS/STLS) * POP3+SSL ("pops") My only option to enforce securely sending user credential is to enable port 995 and disable port 110, sound right?

[Dovecot] Multiple Authentication Databases
by Jonathan Tripathy 11 Jan '11

Hi Everyone, I wish to run Dovecot on my "Front End" outbound mail relay, and use Dovecot purely for authentication purposes. However, each mysql database for each domain will be on a separate server. Is there a way for dovecot to authenticate against different databases depending on domain name? Thanks

[Dovecot] OS X Server Partition Problems
by Bryan Harrison 11 Jan '11

11 Jan '11

I'm a nube to Dovecot and this list. Please be kind. ;) I'm running Dovecot 1.1.20 and Postfix 2.5.5 on OS X Server 10.6.6. I've moved accounts from another, older cyrus-based server (thank god), and used fetchmail to imap the existing mail to the new server. At some point, I developed a problem with my partition map being semi-ignored. Mail is stored in multiple places, and I'm not sure why or entirely clear how it ended up there. My log is overflowing with entries such as… Jan 10 15:44:57 gilded-bat dovecot[65]: auth(default): od(john_doe_com): unable to find partition for tag=johndoe: using default mail location: /var/spool/imap/dovecot/mail …referring to each of my defined partitions. Here's what I semi-understand. /etc/dovecot/partition_map.conf.default contains: default:/var/spool/imap/dovecot/mail /etc/dovecot/partition_map.conf contains correct entries like default:/Mail JohnDoe:/Groups/JohnDoe/Mail [etc.] dovecotd -n is below. It's configuration with regard to mail store locations look ok to me, but then I'm a virgin. In practice, mail is being stored in three different locations. They're all full of mail directories and are busy. /var/spool/imap/dovecot/mail /Mail /Groups/JohnDoe/Mail …with of course the third entry being many entries for each client. The directories described definitely exist. Clients started out being able to see old mail that was transferred from the retired server, but no longer do. I'm not actually clear which of the three mail stores in use are being accessed by whom or for what. (And let's not even ask why none of this showed up in testing.) In short, I'm over my head and the villagers are outside with the usual pitchforks and torches. Thanks, Bryan dovecotd -n # 1.1.20apple0.5: /private/etc/dovecot/dovecot.conf Warning: fd limit 256 is lower than what Dovecot can use under full load (more than 356).

[Dovecot] dsync not copying all mail
by Nick Rosier 10 Jan '11

10 Jan '11

Hi, I'm still trying to migrate from Dovecot 1.2.16 to 2.0.7 on FreeBSD. Previous attempts have failed with mails not being visible after the upgrade. Version 1.2.16 was migrated from maildir to dbox about a year ago via the convert-plugin. After previous attempts to "clean" the hybrid maildir-dbox situation I used imapsync to copy all mails from the old account to a new account. I would assume in this case I get a clean dbox-mailmap. I tried to run dsync on this new map but noticed a lot of mails are not syncing: [vmail@mail ~]$ find /vmail2/new/bunbun.be/nick | wc -l 5329 [vmail@mail ~]$ find /vmail2/old/bunbun.be/nick | wc -l 6134 Any ideas? N.

[Dovecot] Last login
by Egbert Jan van den Bussche 10 Jan '11

10 Jan '11

Hi, I'm trying to find a way to find inactive users. Is there a simple way to deduct the last login date of a user from that users Maildir files? Are the timestamps on the index files reliable? I ask because the system and dovecot logs are not available to me but I can search the whole .../vmail/domain/user/Maildir tree. I'n running 1.2.9 on ububtu 10.04 LTS with posttfix and postfixadmin. The users (all are virtual) reside in the postfixadmin MySQL tables. TNX Egbert Jan (NL)

[Dovecot] Urgent problem: Dovecot fetches the same mails multiple times per POP
by Andi Meier 10 Jan '11

10 Jan '11

I have a problem since a couple of hours: I manage several mboxes on a virtual server using Dovecot (over POP3). Until a few hours ago, it worked well, but since 11:50, the e-mail clients which access Dovecot's mailboxes, receive all e-mails new each time the mailbox is queried. For example: 15:40 fetches 22 new mails 15:41 fetches the same 22 mails again as new 15:42 fetches the same 22 mails again as new etc. Dovecot version is 1.0.15 on Debian Lenny. How can I fix this? How can I diagnose what's wrong? The mailbox files themselves seem ok, no dupe messages. I noticed that in the /var/log/mail.log Dovecot says: ------- START --------- Jan 10 15:27:08 lvps87-230-81-99 dovecot: POP3(office): Disconnected: Logged out top=0/0, retr=23/6273313, del=23/23, size=6272894 Jan 10 15:40:02 lvps87-230-81-99 dovecot: POP3(office): Effective uid=1002, gid=1002 Jan 10 15:40:02 lvps87-230-81-99 dovecot: POP3(office): mbox: data=/var/mail:INBOX=/var/mail/office Jan 10 15:40:02 lvps87-230-81-99 dovecot: POP3(office): mbox: root=/var/mail, index=/var/mail, inbox=/var/mail/office Jan 10 15:40:02 lvps87-230-81-99 dovecot: POP3(office): mbox sync: Expunged message reappeared in mailbox /var/mail/office (UID 3234 < 3261, seq=2, idx_msgs=0) Jan 10 15:40:02 lvps87-230-81-99 dovecot: pop3-login: Login: user=<office>, method=PLAIN, rip=80.122.113.70, lip=87.230.81.99 Jan 10 15:40:02 lvps87-230-81-99 dovecot: POP3(office): mbox sync: UID inserted in the middle of mailbox /var/mail/office (3261 > 3234, seq=2, idx_msgs=24) Jan 10 15:40:02 lvps87-230-81-99 dovecot: POP3(office): mbox sync: UID inserted in the middle of mailbox /var/mail/office (3285 > 3234, seq=2, idx_msgs=24) Jan 10 15:40:22 lvps87-230-81-99 dovecot: POP3(office): mbox sync: UID inserted in the middle of mailbox /var/mail/office (3309 > 3234, seq=2, idx_msgs=24) Jan 10 15:40:22 lvps87-230-81-99 dovecot: POP3(office): Disconnected: Logged out top=2/0, retr=24/6274745, del=24/24, size=6274309 ------- END --------- What puzzles me: Each time the retr=XX value is never decreasing. Shouldn't it be 0/xxxxx the next time when the mails are not kept on the server? Apparently Dovecot does not manage to remove the mails form the mbox, although the email client tells it so (=> del=24/24) Is this the problem? How can I check this? I am very thankful for any hints! Cheers, Andi

[Dovecot] size of "m.XXX" in mdbox
by Joan Moreau 10 Jan '11

Hi, How to tune the size of each "m.xxx" file in mdbox format , in order to optimize the ratio size/number of files ? (I can see for instance more than 100 000 files in one directory due to very large mailbox size) If such parameter exists, what is the typical value ? Thanks Joan

Or use sendmail binary from something else than Courier. Yes i'm using sendmail from Courier.

[Dovecot] CatchAll virtual user removes spamheaders
by Peter Reinhold 09 Jan '11

09 Jan '11

Hi all, I am having a small problem with a catch-all user I have setup in my Postfix/Dovecot setup. I am not 100% sure this is Dovecot related, but, logic tells me it is. I have a virtual user called @reinhold.dk setup to redirect to my main account, peter(a)reinhold.dk. If I send a spam mail (GTUBE) to peter(a)reinhold.dk, the mail is marked with Amavis x-headers as it should be. If I send the same mail to peterpeter(a)reinhold.dk, I can see in my maillog that the mail is PASSED SPAMMY, just as the first one, but when I check the mail, all amavis x-headers are missing. (Except one, X-Spam-Virus-Scanned:, which just informs me that the mail has passed through the scanner) Does anyone know if this is a Dovecot issue? (It seems so to me), and if so, any hints on how I can change this behaviour? Kind Regards, Peter Reinhold - peter(a)reinhold.dk > http://www.reinhold.dk & http://www.geekhouse.dk < -- QOTD : Mit internet er der ikke noget porn på .. Det er helt vildt nederen. ..

[Dovecot] can not receive external emails
by Daminto Lie 09 Jan '11

09 Jan '11

Hi, I am new to Dovecot. Recently I have got a new server running on Ubuntu Server 10.04 with Postfix, Dovecot (for IMAP) and Squirrelmail. During the test, I was able to send & receive emails internally, and can send emails externally. However, I got a problem when it comes to receiving emails externally. The emails I sent from yahoo never arrived to my local inbox. Anyway, I checked the mail.log and found the following dovecot: auth-worker(default): dovecot-auth: /usr/locallib/liblber-2.4.so.2" no version information available (required by dovecot-auth) dovecot: auth-worker(default): dovecot-auth: /usr/locallib/libldap_r-2.4.so.2" no version information available (required by dovecot-auth) dovecot: auth-worker(default): dovecot-auth: /usr/locallib/libldap-r-2.4.so.2" no version information available (required by /usr/lib/libpq.so.5) I was wondering if anyone might be kind to explain the above error messages and how to work around this so that it could send/receive emails coming from external mail server. Thank you in advance

[Dovecot] IMAP Clients can not see 3rd tier nested IMAP directories
by jjs87＠cornell.edu 08 Jan '11

08 Jan '11

I have a very bizarre problem that I hope someone can help me with. I am not sure if this is a Dovecot problem, or IMAP client problem. I recently used Transend's Migrator to move mail from Exchange 2007 to my Dovecot 1.0.7 server. The program seems to have moved the nested IMAP dirs properly as seen below in a directory listing of the maildir dir. The nested dirs have indexes, cur, new dirs as expected. However, when the account is viewed in Windows Thunderbird 3.1.6 or Outlook 2010 the 3rd tier dirs are not seen, nor can they be subscribed to. On a whim, I decided to try Apple Mail 4.3 to view the account and all the IMAP dirs can be seen and accessed as expected. Any idea what is going on? Is this somehow an IMAP client problem (bug) or an issue with Dovecot and these clients? Listing of the Maildir dir: [root Maildir]# ls -al total 92 drwx------ 17 andrew andrew 4096 Dec 6 17:06 . drwx------ 9 andrew andrew 4096 Dec 6 15:58 .. drwx------ 5 andrew andrew 4096 Dec 6 16:31 .mailbox drwx------ 5 andrew andrew 4096 Dec 6 16:31 .mailbox.mail drwx------ 5 andrew andrew 4096 Dec 6 16:48 .mailbox.mail.colleagues drwx------ 5 andrew andrew 4096 Dec 6 17:02 .mailbox.mail.colleagues.amy drwx------ 5 andrew andrew 4096 Dec 6 16:48 .mailbox.mail.colleagues.aslan drwx------ 2 andrew andrew 4096 Dec 6 16:31 cur -rw------- 1 andrew andrew 144 Dec 6 16:31 dovecot.index -rw------- 1 andrew andrew 10272 Dec 6 16:31 dovecot.index.cache -rw------- 1 andrew andrew 128 Dec 6 16:31 dovecot.index.log drwx------ 2 andrew andrew 4096 Dec 6 16:31 new drwx------ 5 andrew andrew 4096 Dec 6 16:53 .Sent Items -rw------- 1 andrew andrew 32 Dec 6 17:06 subscriptions drwx------ 2 andrew andrew 4096 Dec 6 16:31 tmp drwx------ 5 andrew andrew 4096 Dec 6 16:32 .Trash PROBLEM: When viewed in Thunderbird 3.1.6 or Outlook 2010: These nested dirs are seen: ..mailbox ....mail These nested dirs are NOT seen or can be subscribed: ......colleagues ........amy ........aslan OBSERVATIONS: When viewed in Apple Mail 4.3, all dirs are seen correctly.

[Dovecot] Migrate dbox 1.2 virtual mail to 2.0
by Nick Rosier 08 Jan '11

08 Jan '11

Hi, I'm trying to migrate from Dovecot 1.2.16 to 2.0.7. Initially the mails were stored in Maildir format but I changed them to dbox using "fast Maildir migration" and some mails are still in the old maildir format. I'm trying to migrate these mails using dsync but dsync panics: % dsync -D -o mail_location=dbox:/var/spool/vmail/bunbun.be/nick mirror dbox:/var/spool/vmail2/bunbun.be/nick ...... dsync(vmail): Panic: file mail-storage.c: line 1351 (mailbox_save_set_guid): assertion failed: (guid == NULL || *guid != '\0') zsh: abort (core dumped) dsync -D -o mail_location=dbox:/var/spool/vmail/bunbun.be/nick mirror Any ideas?

[Dovecot] Pointers for developing a proper encryption plugin?
by dovecot＠moorooboorai.com 07 Jan '11

07 Jan '11

Hi all, One thing that's always itching when I think about mail-servers, is the storage of e-mail messages in (rather) plain-text. Meaning, any administrator with sufficient privileges would be able to read messages not meant for them. Of course, PGP alike solutions exist, but that's not for the masses. In my opinion I would like to have e-mail messages stored encrypted using a (strong) user-supplied password. That password would ideally be the same as the one the user logs in with. So for me it's okay to place and enforce that requirement on any of the users. Having this in place would for sure reassure external auditors/accountants of any kind. Having Google'd from here to 'yonder and consulting experts on Experts Exhange, I have come up with only this pointer: http://dovecot.markmail.org/search/?q=dovecot+encrypt#query:dovecot%20encry… It mention the same issue, and also mentions the non-existence of a solution (back in May 2010). But, beforing diving into developing solutions myself, I have to be absolutely sure that there isn't any solution yet. And, in consequence of non-existence: what would allow me to fasttrack any development efforts on this? Is there an overview available where I could learn the best approach for plugin development? Tutorials maybe? Kind regards, Jeroen Zuijderhoudt.

[Dovecot] Dovecot 2.0.8 Linux 2.6.12.6-arm1 armv5tejl Segmentation fault

Hi, Sorry. This is what I find when I try to run Dovecot. # dovecot -F Segmentation fault If I comment out the SSL configuration values, then: # dovecot -F doveconf: Fatal: Error in configuration file /opt/etc/dovecot/dovecot.conf: ssl enabled, but ssl_cert not set These are the configure options, "--enable-maintainer-mode" & "--enable-devel-checks" were added with the hope that dovecot would produce a more verbose error message. ./configure --prefix=/opt --with-ssl=openssl --disable-dependency-tracking --enable-maintainer-mode --enable-devel-checks None of the log files have been touched since before this version of Dovecot was installed (logging was initially part of the configuration).

[Dovecot] dovecot can't see mail that is there
by Joachim Ferreira 07 Jan '11

07 Jan '11

I used to install dovecot on any Fedora fresh installation and I could fetch my internal mail few minutes later. Now I've been struggling for two days and I haven't got my mail working yet. I have Fedora 14 with sendmail. Some application on the same machine send mail to an account on the same machine (hence all is confined to one machine) and I want to retrieve it from a laptop on the same LAN via Outlook. If I login into the account and check the mail with the alpine (ex pine) client, I see that there are 10 mails. When I "telnet localhost pop3" and login into the account, the "list" command says there are 0 mails. Various suggestions found on the internet for slightly different configuration did not help.

[Dovecot] Mail delivered, but lost?
by Patrick Ben Koetter 06 Jan '11

06 Jan '11

Running dovecot 1.2.9 on a Ubuntu 10.04.1 LTS virtual machine. Postfix receives messages and hands them over to deliver for local storage. Today two mails came in that could not be found allthough they got delivered. What catches my eye is the "?" in the msgid: Jan 5 21:10:47 mail dovecot: deliver(consulting): msgid=? <14847_1294258245_ZZh0g1h9eLfxL.00_fc2fe6e910f03.4d24de54(a)uni-bielefeld.de>: saved mail to INBOX Jan 5 21:27:26 mail dovecot: deliver(consulting): msgid=? <18995_1294259246_ZZh0g1hhis~T6.00_fc45b33d1281c.4d24e23d(a)uni-bielefeld.de>: saved mail to INBOX Is that a known error?

[Dovecot] dsync backup errors with maildir -> mdbox
by Patrick McLean 06 Jan '11

06 Jan '11

Hi, In preparation for a migration from maildir to mdbox, I am using dsync backup to do initial mailbox copies (at this point I do not want to risk any changes to the maildir). The initial run of dsync runs fine, but a second run to migrate any changes since the first run produces errors for many users. Here is an example of the type of error produced: > # dsync -u user backup mdbox:~/mdbox > # dsync -u user backup mdbox:~/mdbox > dsync(user): Error: Can't delete mailbox INBOX: INBOX can't be deleted. > dsync(user): Error: Can't delete mailbox directory XXXXXX.courses: Mailbox has children, delete them first > dsync(user): Error: Can't delete mailbox directory XXXXXX: Mailbox has children, delete them first > dsync(user): Error: Can't delete mailbox directory XXXXXX.XX1: Mailbox has children, delete them first > dsync(user): Error: Can't delete mailbox directory XXXXXX.XX2: Mailbox has children, delete them first > dsync(user): Error: Can't delete mailbox directory XXXXXXXX: Mailbox has children, delete them first > dsync(user): Error: Can't delete mailbox directory XXX: Mailbox has children, delete them first > dsync(user): Error: Trying to open a non-listed mailbox with guid=c0204a140fdd254d1a770000743562c1 > dsync(user): Error: msg iteration failed: Couldn't open mailbox c0204a140fdd254d1a770000743562c1 > dsync(user): Error: Trying to open a non-listed mailbox with guid=c0204a140fdd254d1a770000743562c1

[Dovecot] Alternative storage vs. Self healing (losing flags?)
by Marczisovszky Daniel 06 Jan '11

06 Jan '11

Hi, We are going to set up an environment for our customers where the storage is provided by two servers. First one stores the new emails, second one stores all the others using Dovecot's alternative storage feature (mailbox format is mdbox). The servers are connected via NFS. If, for any reason, the alternative storage is not mounted, Dovecot will see only an empty folder and due to its self-healing functionality flags for messages stored on alternative storage will be lost. Is there any way to prevent regenerating indexes (and especially flags as a side-effect) if the alternative storage seems to be completely empty? (like a dummy file in the root of the alternative storage and an option to enable/disable this check) Thanks in advance, Daniel Marczisovszky

[Dovecot] Login with firstname.lastname instead of loginname - WORKING
by Ralf Hildebrandt 06 Jan '11

06 Jan '11

3 years ago (!) I aksed about this and finally I implemented it today: >> # NEW >> passdb { >> driver = passwd >> # firstname.lastname@charite.de:password:uid:gid:(gecos):home:(shell):user=realloginname >> args = /usr/local/etc/dovecot.login_via_email >> } >If you're only using it as a passdb, you don't need the uid/gid/home. So >an example field would be: > >firstname.lastname@charite.de:password::::::user=realloginname But now I'm encountering problems with users writing Firstname.Lastname(a)charite.de instead of firstname.lastname(a)charite.de (capitalized first letters) How can I "normalize" the usernames by lowercasing them? The coolest solution would be to strip realms AND force lowercasing of usernames in one pass -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | http://www.charite.de

[Dovecot] Upgrade from 1.2.16 with sieve/managesieve to 2.0.8 with pigeonhole
by Nick Rosier 06 Jan '11

06 Jan '11

Hi, I would like to upgrade my server from 1.2.16 with sieve and managesieve to 2.0.8 with pigeonhole. Will I get all functionality I was having before? Should this migration be painless or will it require some additional work? I've read the Upgrading guide so I know I need to create an additional user. I've migrated the mails from Maildir to dbox in the past (using the convert plugin); does that mean I'm fully dbox or am I in a maildir-dbox hybrid situation? I've noticed that there are still some maildir-formatted mail (e.g. 1259960330.M322229P62710.mail,W=2195:2,S) in some of the maps. root@mail /usr/local/etc # dovecot -n # 1.2.16: /usr/local/etc/dovecot.conf # OS: FreeBSD 8.2-PRERELEASE amd64 zfs protocols: imap imaps managesieve ssl_ca_file: /etc/ssl/cert.pem ssl_cert_file: /etc/ssl/mail.crt ssl_key_file: /etc/ssl/mail.key version_ignore: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(managesieve): /usr/local/libexec/dovecot/managesieve-login valid_chroot_dirs: /var/spool/vmail mail_max_userip_connections(default): 50 mail_max_userip_connections(imap): 50 mail_max_userip_connections(managesieve): 10 verbose_proctitle: yes first_valid_uid: 5000 first_valid_gid: 5000 mail_privileged_group: mail mail_location: dbox:/var/spool/vmail/%d/%n mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(managesieve): /usr/local/libexec/dovecot/managesieve mail_plugins(default): acl imap_acl fts fts_squat autocreate mail_plugins(imap): acl imap_acl fts fts_squat autocreate mail_plugins(managesieve): mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(managesieve): /usr/local/lib/dovecot/managesieve imap_client_workarounds(default): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(managesieve): dict_db_config: /usr/local/etc/dovecot-db.conf namespace: type: private separator: / inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)xxx.xxx mail_plugins: sieve acl mail_plugin_dir: /usr/local/lib/dovecot/lda deliver_log_format: msgid=%m: %$ sendmail_path: /usr/sbin/sendmail auth default: mechanisms: plain login cram-md5 username_format: %Lu passdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: sql args: /usr/local/etc/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail plugin: acl: vfile:/usr/local/etc/dovecot/acls:cache_secs=300 acl_shared_dict: file:/var/db/dovecot/shared-mailboxes.db convert_mail: maildir:/var/spool/vmail/%d/%n expire_dict: proxy::expire expire: Trash 365 sieve: /var/spool/vmail/%d/%n/dovecot.sieve sieve_dir: /var/spool/vmail/%d/%n/sieve sieve_global_dir: /usr/local/etc/dovecot/sieve fts: squat fts_squat: partial=4 full=10 autocreate: Trash autocreate2: Drafts autocreate3: Spam autocreate4: Sent autosubscribe: Trash autosubscribe2: Drafts autosubscribe3: Spam autosubscribe4: Sent dict: expire: db:/var/db/dovecot/expire.db

[Dovecot] RFC: grouped (f)sync
by Attila Nagy 06 Jan '11

06 Jan '11

Hello, Currently Dovecot (and any other application, which cares about e-mail delivery) does at least one fsync per mail delivery. Given that hard disk drives have a very limited IOPS, this effectively limits the maximum mail delivery performance to a very low value, under utilizing the available storage IO capacity. Calculating with an average mail size of 50 kB and an average consumer HDD with 120 IOPS, the theoretical mail delivery performance will be 50 kB*120 IOPS=5.85 MBps. But if we could write 500 kB with every transaction, the delivery speed would be nearly 10 times as well. Dovecot have two process models: separate processes for each client connection and an async in-process multiplexing method. This works for each one, albeit the timing is somewhat different. So here's the idea: instead of fsyncing immediately in the LDA (lmtpd) every time when the client says "\r\n.\r\n" after the DATA phase, let's introduce a user settable timer (let's call that sync_delay from now on) and only sync in every sync_delay seconds. This would introduce an up to sync_delay seconds delay in lmtpd returning "250 Ok" to the client, but that's generally not a problem, because in high traffic setups there is a great amount of concurrency, so you could use a lot of client connections easily. Take an example setting of sync_delay = 100 ms. With this, 10 syncs would happen in every second from Dovecot LDA processes, meaning if a client connects in t=0 it will immediately got the response 250, if a client connects in t=0.05, it will get the response in 50 ms (in an ideal world, where syncing does not take time), and the committed blocks could accumulate for a maximum of 100 ms. In a busy system (where this setting would make sense), it means it would be possible to write more data with less IOPS needed. I can see two problems: 1. there is no call for committing a lot of file descriptors in one transaction, so instead of fsync() for each of the modified FDs, a sync() would be needed. sync() writes all buffers to stable storage, which is bad if you have a mixed workload, where there are a lot of non-fsynced data, or other heavy fsync users. But modern file systems, like ZFS will write those back too, so there an fsync(fd) is -AFAIK- mostly equivalent with a sync(pool on which fd is). sync() of course is system wide, so if you have other file systems, those will be synced as well. (this setting isn't for everybody) 2. in a multiprocess environment this would need coordination, so instead of doing fsyncs in distinct processes, there would be one process needed, which does the sync and returns OK for the others, so they can notify the client about the commit to the stable storage. Any opinions on this?

[Dovecot] virtual user problems
by G.Nau 06 Jan '11

06 Jan '11

dovecot 2.0.8 with postfix; transfer postfix -> dovecot by lmtp is fine Now i have to redirect a couple of virtual email names (like admin(a)mydomain.com, postmaster@, webmaster@, info@, sales@ ...) to a single user postbox named xxx@mydomain. As I use mysql for the auth-sql, it's returning userhome /home/<name>/maildir for all sql requests to <name>=admin, postmaster etc. I also verified that "doveadm user info" is returning the maildir/home: /home/xxx/maildir So I assumed, that all mails to admin, postmaster etc. are transfered to user xxx mailbox. But it isn't. Dovecot is creating the maildirs /home/admin/maildir, /home/info/maildir and so on. What do I miss here to get that virtual users mapped to the correct user xxx? Regards Birte

[Dovecot] case (non-)sensitivity for folder names
by Phil Howard 06 Jan '11

06 Jan '11

Is IMAP supposed to be case sensitive or case in-sensitive? It seemed it would be case sensitive because I've had different cases of folders. But today I found I had two folders "Spam" and "spam", with directories ".INBOX.Spam" and ".INBOX.spam" on the server. Messages existed in each directory on the server and they were different. The messages could be read from Evolution. However, the list of messages had info mixed up between the folders. I then selected all messages in one of the folders and trashed them (click on trash icon). Messages disappeared in BOTH folders. On the server, after a couple minutes delay, messages in BOTH directories were flagged "T". That doesn't seem right. But I don't know enough about what IMAP is supposed to do, or on which end the names of folders get remapped into directory names, to even guess which is messed up here. I do know Evolution keeps a track of what it thinks the folder has, because in the past I have just "rm -fr" on a folder directory and Evolution still showed each message in its list, although it could not access them. Anyone know what's the deal with that? Unfortunately, there seems to be no operation in Evolution to tell it to discard its own cache. I'm also wondering if life would be any better if I used Thunderbird. -- sHiFt HaPpEnS!

[Dovecot] courier-dovecot-migrate.pl maintaining order of pop3 uidl's
by Mark Zealey 05 Jan '11

05 Jan '11

Hi there, I've just been experimenting with the latest courier-dovecot-migrate.pl script and I notice that it favours keeping pop3 UIDL ordering rather than IMAP UID preservation. There is this comment (line 312): # POP3 clients may want to get POP3 UIDLs in the same order always. # Preserve the order even if it causes IMAP UIDs to change. Does anyone have details as to which clients this actually causes a problem with? If it's some really old software then perhaps we'd prefer to keep the imap UID's the same but change the POP3 UIDL ordering (not the UIDL numbering though of course) Thanks, Mark

[Dovecot] dovecot + sendmail, what LDA setup?
by David Cake 05 Jan '11

05 Jan '11

I have an existing setup with sendmail, dovecot, on debian. I want to move LDA and move from using mbox to using Maildir. I have only 'real' users and aliases, no virtual users. What is a recommended, trouble free, LDA setup? procmail is of course on possibility, but I'd be unlikely ever to use any of its advanced features, just simple local mail delivery. I'd like to use deliver, but most of the dovecot as LDA sample configs I have seen seem to assume I am using it for virtual users. Advice? Pointers to a simple working setup for sendmail, dovecot, Maildir? Cheers David

[Dovecot] re-indexing moved mail
by Phil Howard 05 Jan '11

05 Jan '11

I have a huge block of email that was misdelivered into the wrong folder. Moving it where it should be is not just all from one folder to being all of another folder. Basically, the index files need to be rebuilt. Looking in the wiki I cannot find how to do this. It all seems to be about installation, and no administrative tools. Or would it be just as simple as delete certain index files and they would be automagically rebuilt? -- sHiFt HaPpEnS!

[Dovecot] Error copying >1 message to virtual mailbox
by Nicholas Riley 05 Jan '11

05 Jan '11

I created a virtual mailbox which maps to a single physical mailbox (in Dovecot 1.x I did this with a symlink but had intermittent problems with Dovecot 2.0 doing the same.) However, I can only copy one message at a time into the mailbox. If I try to copy more, I get: 7.16 UID COPY 48531:48532 !/Saved 7.16 NO [CANNOT] Can't save messages to this virtual mailbox whereas this works fine: 10.16 UID COPY 48531 !/Saved 10.16 OK Copy completed. The dovecot-virtual file in !/Saved is: !2011-01 all and dovecot.conf: # 2.0.8 (cde0d403c6ff): /etc/dovecot/dovecot.conf # OS: Linux 2.6.18.8-linode22 i686 Debian 5.0.7 mail_location = maildir:~/Maildir:LAYOUT=fs:INBOX=~/Maildir/INBOX:CONTROL=~/.dovecot.cont rol:SUBSCRIPTIONS=.subscriptions mail_max_userip_connections = 20 namespace { inbox = yes location = prefix = separator = / } namespace { location = virtual:~/Maildir/! prefix = !/ separator = / } passdb { driver = pam } plugin { antispam_backend = dspam antispam_signature = X-DSPAM-Signature antispam_spam_pattern_ignorecase = *spam } protocols = imap ssl = required ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { mail_plugins = " virtual" } Thanks. -- Nicholas Riley <njriley(a)illinois.edu>

[Dovecot] Converting from Maildir - sdbox
by Marc Perkel 04 Jan '11

04 Jan '11

OK - I thought this was going to be easy. Maybe it is. I'm just not that good at reading directions. Trying to use dsync. Getting this error: Mail locations must use the same virtual mailbox hierarchy separator (specify separator for the default namespace) Currently using maildir. The setup is as follows: mail_uid = mail mail_gid = mail mail_location = maildir:/vhome/%d/home/%n:INDEX=/imap-cache/%d-%n I don't have any namespace setting. Not quite sure what a namespace is or why I need one. This is what I'm trying to run: dsync -u marc(a)perkel.com backup sdbox:/email/%d/home/%n What I'm hoping to do is do a mass conversion while running. Then shut it down - do a second quick pass - and bring it up in sdbox format. Thanks in advance.

[Dovecot] dovecotpw missing (2.0.8)
by Kristina Clair 04 Jan '11

04 Jan '11

Hello, I just installed dovecot version 2.0.8 from the source tarball. After doing ./configure, make, and make install, I don't have the dovecotpw binary anywhere. It is not in /usr/local/bin or /usr/local/sbin where the other binaries are; I also did a find / for it and don't see it. Is there some configuration flag I'm missing? I read the flags in ./configure --help and nothing seems obviously applicable to me. Is there a cryptography library I could be missing? I have the libs installed for crypt, md5, etc. Thanks, Kristina

[Dovecot] namespaces and noselect
by Kyle Wheeler 04 Jan '11

04 Jan '11

Hello, I am trying to use two namespaces to create an "archival" directory that is stored as mboxes (the rest of my tree is all stored as maildirs). However, when I add the second namespace, suddenly Dovecot starts emitting, in response to the LIST command, a second version of the INBOX that is marked as \NoSelect. Here are my namespac definitions... am I doing this wrong? namespace { list = yes hidden = no inbox = yes location = maildir:~/Maildir prefix = separator = / type = private } namespace { hidden = yes # do not list as a separate namespace list = no # inbox = no location = mbox:~/Maildir/Archive:LAYOUT=fs:INDEX=~/Maildir/ArchiveIndexes/ prefix = INBOX/Archive/ separator = / type = private } ~Kyle -- If you are going through hell, keep going. -- Winston Churchill

[Dovecot] Finally upgrading from v1.0.15 to v1.2.16 -- advice please
by Jan-Frode Myklebust 04 Jan '11

04 Jan '11

It's long over due, but now I finally plan on upgrading from v1.0.15 to v1.2.16 on our servers. Would appreciate any comments! We have 7 servers, all running of the same GPFS filesystem. Both maildirs and indexes are stored here. We use dovecot for POP/IMAP and deliver. Currently we're using mysql as authentication source, but want to move to using ldap instead. Can we upgrade one server at a time, or do we need to upgrade all servers at the same time ? http://wiki2.dovecot.org/Upgrading/1.1 says "Index files have slightly changed as well. Upgrading to v1.1 should go transparently, but moving back to v1.0 might again cause some errors." which makes me think we can't have both versions running against the same users ? Also, if we upgrade only one server, should we switch to "mmap_disable=no" on this one, or keep running with "mmap_disable=yes" on all servers ? "NFS users should now set mail_nfs_storage=yes and mail_nfs_index=yes." Does this apply to any shared/networked filesystems, and is this relevant for GPFS ? The sql queries we're doing now is: password_query = select U.Account as user,S.Password as password from Users U, UserSession S where U.Account=S.Account and U.Account='%u' user_query = SELECT 3000 as uid, 3000 as gid, concat(concat('maildir:', MailDir), concat(':INDEX=', replace(MailDir, '/usr/local/atmail/users', '/usr/local/atmail/users/indexes'))) as mail, concat('maildir:storage=', UserQuota) as quota FROM Users WHERE Account = '%u' I plan on doing ldap bind() for authentication: hosts = maildb3.example.net:389 auth_bind = yes ldap_version = 3 base = ou=people,o=%d,o=ISP,o=example,c=net deref = never scope = onelevel user_filter = (&(objectClass=altiboxperson)(uid=%n)) default_pass_scheme = SSHA but the user_query is a challenge.. In LDAP we have: uid = janfrode, ou=people,o=domain1.net,o=ISP,o=example,c=net mail = janfrode(a)domain1.net mailMessageStore = /usr/local/atmail/users/j/a/janfrode(a)domain1.net mailQuota = 1000000 domain = domain1.net userPassword = SSHA-string So, outside of the user_attrs we need: mail_uid = 3000 mail_gid = 3000 But I'm having a hard time understanding how I can use the ldap value mail=/usr/local/atmail/users/j/a/janfrode(a)domain1.net to translate into dovecot's "mail" containing both "maildir:" and "INDEX=". Does the below look correct ? user_attrs = mailMessageStore=mail=maildir:%$:INDEX=/usr/local/atmail/users/indexes/%1u/%1.1u/%u, mailQuota=quota_rule=*:storage=%$ i.e. will it point dovecot at: mail = maildir:/usr/local/atmail/users/j/a/janfrode@domain1.net:INDEX=/usr/local/atmail/users/indexes/j/a/janfrode@domain1.net quota_rule=*:storage=1000000 -jf

[Dovecot] Vpopmail + Expire Plugin
by Oliver Lehmann 04 Jan '11

04 Jan '11

Hi, I've changed my running qmail/vpopmail/procmail/courier-imap/sqwebmail installation to qmail/vpopmail/siege/dovecot/horde imp. So far, I've got everything running. Authentification with vpopmail as passdb is working, Mail delivery with siege into different Mail folders is working as well. One of the reasons why I switched to dovecot was the expire plugin and right now I'm trying to set it up but I don't get it to run. - I created a MySQL User as advised - I created a database and a table and granted SELECT, INSERT, DELETE, UPDATE privileges for that table to user dovecot # mysql -udovecot -p dovecot Enter password: mysql> desc expires; +--------------+--------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +--------------+--------------+------+-----+---------+-------+ | username | varchar(75) | NO | PRI | NULL | | | mailbox | varchar(255) | NO | PRI | NULL | | | expire_stamp | int(11) | NO | | NULL | | +--------------+--------------+------+-----+---------+-------+ 3 rows in set (0.00 sec) mysql> select * from expires; Empty set (0.00 sec) - I added the following lines to my dovecot.conf: dict { expire = mysql:/usr/local/etc/dovecot/dovecot-dict-sql.conf.ext } plugin { expire = Test expire_dict = proxy::expire } - I created the dovecot-dict-sql.conf.ext # cat /usr/local/etc/dovecot/dovecot-dict-sql.conf.ext connect = host=localhost dbname=dovecot user=dovecot password=XXXX map { pattern = shared/expire/$user/$mailbox table = expires value_field = expire_stamp fields { username = $user mailbox = $mailbox } } # - When restarting dovecot I had a dict error because the socket was owned by root. I changed that so the socket is owned by the user vpopmail. - Then I created a folder "Test" via IMAP for one of my accounts - Then I copied via Horde IMP (so via IMAP) a message to that new folder - I requeried dovecot.expires in my database and it is still empty - I enabled logging for my MySQL DB and with that I found out, that no connect with the "dovecot" user is made at all so of course the table is empty. - I created a siege rule to move a mail directly to that Test folder when a specific Subject is used. lda moves the mail on arrival but still no MySQL connection is made. I've read that doveadm -A must work to get the expire plugin workinj, but it does not: # doveadm search -A mailbox INBOX subject test doveadm(olivleh1): Error: User listing returned failure doveadm: Error: Failed to iterate through some users # The expire plugin is loaded on startup: Jan 04 11:35:50 imap: Debug: Loading modules from directory: /usr/local/lib/dovecot Jan 04 11:35:50 imap: Debug: Module loaded: /usr/local/lib/dovecot/lib20_expire_plugin.so When using doveadm I'm getting a strange error: # doveadm -v expire -A mailbox INBOX subject test doveadm(olivleh1): Fatal: Unknown command 'expire', but plugin expire exists.

[Dovecot] Automatic Debian Dovecot repository now also includes amd64 binary packages.
by Stephan Bosch 04 Jan '11

04 Jan '11

Hi, I've recently significantly improved the automated Dovecot Debian package builder. At the beginning it only produced i386 binaries for Debian testing. A few weeks back I added a slave builder that builds packages for Debian stable. Today I have extended the slave builder with support for multiple architectures and I've added amd64 binaries to the repository. The master builder still builds packages for testing/i386 every hour. The slaves check for new source packages about 20 minutes later. Read the following wiki page for more information and read it carefully when you are considering to use these packages: http://wiki.dovecot.org/PrebuiltBinaries#Automatically_Built_Packages Also, every day at four 'o clock in the morning, the latest source packages are uploaded to the openSUSE build service, which builds i386/amd64 binaries for several Ubuntu versions (experimental): http://download.opensuse.org/repositories/home:/sbosch:/ Regards, Stephan.

[Dovecot] Problem with requiring client certificates for external connections
by Frank Crawford 04 Jan '11

04 Jan '11

Folks, I'm trying to configure my dovecot installation to require client certificates for external/Internet connections, while still allowing my local network to not need certificates. This configuration is for Dovecot 2 (2.0.8 in Fedora 14), and I've tried to use the "remote" block to give different definitions for my local network vs the defaults. While most options seem to be set fine, if I set "auth_ssl_require_client_cert" to yes as the default, and reset it to no for my local network, dovecot still requests a client certificate and fails as one is not supplied. Am I correct that it can be reset in a "remote" block, or is it treated differently to other options? In fact do I have the configuration correct, as there doesn't really seem to be anything documenting "remote" or "remote_ip" or related items for Dovecot 2. Related to this, much of the documentation states that the variable is "ssl_require_client_cert", seems to be accepted by ignored, vs "auth_ssl_require_client_cert" which does have some effects. Also, in the configuration dump, it duplicates the netmask. The configuration is below, as generated with "dovecot -n". Regards Frank # 2.0.8: /etc/dovecot/dovecot.conf # OS: Linux 2.6.36.1 x86_64 Fedora release 14 (Laughlin) ext4 auth_ssl_require_client_cert = yes mail_location = maildir:/var/spool/maildir/%u 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 mbox_write_locks = fcntl passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = postmaster(a)crawford.emu.id.au ssl = required ssl_ca = </etc/pki/CA/cacert.pem ssl_cert = </etc/pki/tls/certs/dovecot.crt ssl_key = </etc/pki/tls/private/dovecot.key ssl_verify_client_cert = yes userdb { driver = passwd } protocol pop3 { pop3_uidl_format = %v.%u } remote 203.16.204.0/24/24 { auth_ssl_require_client_cert = no disable_plaintext_auth = no ssl = no ssl_verify_client_cert = no } remote fdd2:7aad:d478:1::/64/64 { auth_ssl_require_client_cert = no disable_plaintext_auth = no ssl = no ssl_verify_client_cert = no } remote 2001:44b8:62:140::/64/64 { auth_ssl_require_client_cert = no disable_plaintext_auth = no ssl = no ssl_verify_client_cert = no }

[Dovecot] Courier-mta with Dovecot LDA again
by komodo 04 Jan '11

04 Jan '11

Hi all Sorry for repost, but i don't believe that there is noone who know where the problem can be. At least developers should know :-) I have sent this post once, but without answer. I have setup dovecot lda instead of maildrop on my courier server. Delivery is working, sieve plugin too, but i can't figure out why lda can't send emails via sendmail (vacation). I always get error Error: Sendmail process terminated abnormally, exit status 67 And i know why, but i don't know how to setup lda to make it work . Here is .courier file where is redirect to lda. | /usr/libexec/dovecot/deliver -a $RECIPIENT -f $SENDER But the deliver does not pass recipient address to sendmail. Here is some output of strace execve("/usr/libexec/dovecot/deliver", ["/usr/libexec/dovecot/deliver", "-a", "komodo@somedomain", "-f", "someuser@somedomain"], [/* 22 vars */]) = 0 So it's clear that deliver have those variables, but then i can see this execve("/usr/sbin/sendmail", ["/usr/sbin/sendmail", "-i", "-f", "<>", "--", "someuser@somedomain"], [/* 2 vars */] <unfinished ...> And there is empty -f , so here is the problem. How should i setup this to make it work correctly ? Here is my config [root(a)OVZ.mail ~]# dovecot -n # 2.0.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-194.8.1.el5.028stab070.5 x86_64 CentOS release 5.5 (Final) disable_plaintext_auth = no hostname = ovzmail listen = 10.0.10.34 mail_location = maildir:~/Maildir 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 mbox_write_locks = fcntl namespace { inbox = yes location = prefix = INBOX. separator = . type = private } namespace { location = maildir:/home/shared/Maildir prefix = spam_learner. separator = . type = public } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap sieve ssl_cert = </etc/pki/dovecot/certs/server.pem ssl_key = </etc/pki/dovecot/private/server.pem userdb { driver = prefetch } protocol lda { mail_plugins = " sieve" } protocol imap { mail_max_userip_connections = 40 } Many thanks Martin

[Dovecot] Quota ignore subfolders
by Héctor Moreno Blanco 04 Jan '11

04 Jan '11

Hello, We have dovecot 2.0.8 in our servers with Scientific Linux SL release 5.2 (Boron). We want to ignore a mailbox and its child mailboxes. A few weeks ago Timo told me to do this in dovecot.conf, create a new namespace which will be the quotaless namespace and edit the quota: namespace { inbox = yes location = prefix = INBOX. separator = . type = private } namespace { location = maildir:%h/Maildir/carpeta1 prefix = carpeta1. separator = . type = private } plugin { quota = maildir:carpeta1:ns=INBOX. quota_warning = storage=75%% /usr/local/dovecot/bin/quota-warning.sh 75 quota_warning2 = storage=90%% /usr/local/dovecot/bin/quota-warning.sh 90 } We also have passdb and userdb with ldap, with dovecot-ldap.conf: pass_filter = (&(objectClass=qmailUser)(uid=%u)(accountActive=TRUE)) pass_attrs = uid=user,userPassword=password, mailQuotaSize=quota_rule=*:bytes=%$ user_attrs = mailMessageStore=home, mailQuotaSize=quota_rule=*:bytes=%$ user_filter = (&(objectClass=qmailUser)(|(mailAlternateAddress=%u)(mail=%u)(uid=%u))(accountActive=TRUE)) We also tried the easy solution which was to indicate a quota rule in order to ignore the mailbox but with no success. It still get every mailbox to calculate the quota. We set mail_debug=yes to see if there was any error, but everything seemed to be ok. Any suggestions? Thank you very much in advanced.

[Dovecot] Renaming IMAP folders does not affect children
by Johannes Simon 04 Jan '11

04 Jan '11

Hi, we're using dovecot2.0 since August and very happy with it. Just recently Thunderbird users reported problems when renaming folders, and it seems that RFC 2060 (sec. 6.3.5) requires children of a renamed folder to be renamed, too. This however does not happen: Talking IMAP I get: * LIST (\HasChildren) "." "INBOX.NNN1" * LIST (\HasNoChildren) "." "INBOX.NNN1.NNN1a" . rename "INBOX.NNN1" "INBOX.NNN2" * LIST (\HasNoChildren) "." "INBOX.NNN1.NNN1a" * LIST (\HasNoChildren) "." "INBOX.NNN2" There seems to be no problem the filesystem rights, since this works: . rename "INBOX.NNN1.NNN1a" "INBOX.NNN2.NNN1a" * LIST (\HasChildren) "." "INBOX.NNN2" * LIST (\HasNoChildren) "." "INBOX.NNN2.NNN1a" Am I misunderstanding RFC 2060, or is my config wrong (doveconf -n below), or could it be a bug?

[Dovecot] user xxx@mydomain.com doesn't exist
by G.Nau 04 Jan '11

04 Jan '11

new setup of Dovecot 2.0.8 with postfix local users are simply defined as Linux users named xxx, yyy et cetera; IMAP access is fine with that users. Postfix is delivering mails with two domains (to xxx(a)mydomain.com or xxx(a)mydomain.org) and these are rejected by dovecot with 550: user doesn't exist. I've tested the possible usernames with "doveadm user" xxx: okay xxx(a)mydoman.com: "userdb lookup: user xxx(a)mydomain.com doesn't exist" xxx(a)mydoman.org: "userdb lookup: user xxx(a)mydomain.org doesn't exist" Dovecot2 wiki says "Dovecot doesn't care much about domains in usernames" Okay, how to I get dovecot to ignore the domain part (or accept the two defined domains) when mails are delivered from postfix? Or do I have to configure Postfix to strip the domain part before delivering to dovecot? Regards Birte Nauer

[Dovecot] archiving
by PA 03 Jan '11

03 Jan '11

Hi, recently I installed the newest 2.x version of dovecot working with postfixadmin/mysql and it works great, thanks Timo, however I been reading dovecot's mailing list archived messages and haven't run across a good solution for archiving mail with dovecot. There was mention of using rsync but I was looking for incoming mail to be copied to another folder, maybe called archive J, in real time where the user would have only read access to the messages in the archive folder and the expire plug-in would delete messages older then x number of days. Does anyone have an suggestions on how I can implement this, I would also like to hear how some people were implement archiving if they do it differently. Also as far as shared calendars with dovecot what are my options. Sorry if it's a little off topic. Thanks, Paul

[Dovecot] dovecot director terminate ssl ?
by Jan-Frode Myklebust 03 Jan '11

03 Jan '11

I plan on putting two dovecot directors in front of our backend dovecot pop/imap servers, instead of our current haproxy loadbalancing of the connections -- but how do we handle SSL in such a setup. Will all SSL be terminated on the directors automatically, and then proxyed plain text, or is there any configuration needed to achieve this ? Does it matter that the directors are v2.0 while the backends are running v1.2 ? -jf

[Dovecot] Dovecot Quota plugin as Couier quota
by Antonio Perez-Aranda 03 Jan '11

03 Jan '11

I get a similar behavior between dovecot quota plugin and courier quota with the attached patch. When the client change flags, then is forced to recalc. This is because I don't know how to get the changed flags on quota sync method. The courier quota behavior is avoid to count all deleted mails, include "mark as deleted" mails. -- Antonio Pérez-Aranda Alcaide aperezaranda(a)yaco.es Yaco Sistemas S.L. http://www.yaco.es/ C/ Rioja 5, 41001 Sevilla Teléfono +34 954 50 00 57 Fax +34 954 50 09 29

new Dovecot 2.0.8 installation on Opensuse 11.3 I got the error "lmtp (xxx(a)mydomain.yy) Error: user xxx(a)mydomain.yy: Initialization failed: Namespace '': mbox: mbox requires client_limit=1 for service" while trying to transfer mails by lmtp from postfix to dovecot. I googled and looked on the dovecot wiki about this client_limit issue, but no success. What's the syntax of the client_limit and where to place it? Into which config file? Inside the global namespace doesn't seems to work (error on dovecot start). -What's the side effect of this setting to my IMAP clients? Are multiple imap connections to the same mailbox still possible? Regards Birte Nauer

[Dovecot] listescape breaks acl plugin
by Jens 02 Jan '11

02 Jan '11

Hi all Without the listescape plugin I see the following things happen: - If I share a mailbox, dovecot-acl-list in Maildir root is updated accordingly. - If I create a subfolder in an already shared mailbox the dovecot-acl file of the parent folder is copied to the new folder and dovecot-acl-list is updated as well. When I activate the "listescape" plugin, this doesn´t happen. Additionally (with listescape enabled), if I create a folder which contains a dot and then share that folder the dovecot-acl-list looses all entries except the first found shared folder without a dot in foldername. I Hope this is not a bug but only a configuration issue. Thanks for any hints in advance and best Regards Jens

[Dovecot] Shared Folders via Symlinking
by Adrian Mardlin 01 Jan '11

01 Jan '11

Hi folks, I'm trying to set up shared folders via symlinking and have come across a problem. I created a folder for one user, then symlinked it to another. I figured that one thing that is likely to happen at some point is that user 2 is going to decide they don't want to look at that folder any more, and will delete it, so I tried this. Much to my relief, it didn't delete the actual mails, just the symlink. However, it did alter the dovecot.index.cache file to indicate that the folder had been removed, and subsequent attempts to select this folder via the primary user resulted in an error, "NO Mailbox was deleted under us". I had to delete dovecot.index.cache to get it working again. Sorry - can't bring myself to call folders mailboxes... ;-) Adrian Mardlin in charge @ The Very Good Email Company t 01442 892641 m 07920 102401 f 01442 808081 w www.verygoodemail.com The content of this email and any attachment is private and may be legally privileged.

[Dovecot] Sieve rule issue with certain character sets
by Thomas Leuxner 01 Jan '11

01 Jan '11

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have a global sieve rule in place to filter mailing-lists. This has worked well so far.

[Dovecot] Dovecot 1.2.12 + Postfix + virtual domains: delivering to system users
by Ran Talbott 01 Jan '11

01 Jan '11

As mentioned in my previous posting, I've set up a mailserver for a domain of Winboxen, authenticated through Active Directory. After some struggles, I finally got that working. But I also need to receive emails for a few system users on the mailserver (like postmaster, and a couple of accounts set up for maintaining the system). I thought, based on the way I read the documentation, that I could just add a "userdb passwd", ahead of the "userdb ldap", and deliver would find their home directory maildirs. The virtual users would fail the passwd search, fall through to the LDAP check, and deliver would drop their mail into their maildirs in the /var/mailstore tree. I knew the system users wouldn't be able to login to the IMAP server, but this isn't a concern. Instead, the system users' mail got bounced, after an auth check via the "master" socket (from Postfix, I guess: it's a transient process) whose details don't get logged. And the virtual users' lookups (done by deliver) returned made-up UIDs and GIDs, and maildir locations (/home/<realm>/<username>) completely different from what the LDAP lookup normally returns (/var/mailstore/<username>). So what am I missing here? I managed to work around this by adding the system users to the Postfix virtual.db, but it would be nice to not need to do that. It would also be nice to neable the system users to check email by logging in to the IMAP serve, but I'm reluctant to even try that after the way delivery went completely wonky. Thanks, Ran

[Dovecot] Can doveadm rebuild thread indexes?
by David Warden 30 Dec '10

30 Dec '10

I'm already using "doveadm search" to update my squat fts indexes (dovecot.index.search and dovecot.index.search.uids) but I'd like to also update dovecot's thread index file (dovecot.index.thread) using doveadm. I checked the new wiki and the archives but didn't see any option for this. (I'm running 2.0.8) The alternative (AFAIK) is to write a script that signs in to IMAP and does "thread references UTF-8 ALL" in each folder. As an aside, could the dovecot LDA do any of this work? I'd surely be willing to spend the resources at delivery time to keep those indexes updated if it meant I didn't have to run a cron job to keep them updated. -David Warden

[Dovecot] LDAP binds
by Trever L. Adams 30 Dec '10

30 Dec '10

I am using 2.0.8. Anonymous binds are no longer supported in the environment I am using. I need to change my userdb ldap setup to bind. I believe the ldap server does Kerberos (or can) authentication. My users are authenticating using Kerberos or Kerberos/PAM. This needs to stay in place. Can anyone suggest how I might go about changing my setup to work? My current ldap setup is as follows (the directories, user id, etc are set statically in the configuration elsewhere): tls = yes hosts = MAILSERVER base = dc=middleearth,dc=sapphiresunday,dc=org ldap_version = 3 user_attrs = userPrincipalName=user user_filter = (&(objectClass=person)(|(mail=%u)(sAMAccountName=%u)(userPrincipalName=%u))) # For using doveadm -A: iterate_attrs = userPrincipalName=user iterate_filter = (objectClass=person) Thank you, Trever Adams -- "Seize the day, put no trust in the morrow!" -- Quintus Horatius Flaccus (Horace)

[Dovecot] dovecot-keywords problem with MDN
by Mauro D. 30 Dec '10

30 Dec '10

Hi all, I have Dovecot 1.2.13 installed. My clients ask why Disposition-Notification is requested every time the mail is moved on a new IMAP folder... I take a look into dovecot-keywords file and I see that: 1) I have only one row 0 NonJunk 2) dovecot-keywords file is not present inside every directory. How I can restore normal status? Where is probably the problem? Thanks Mauro D.

[Dovecot] IMAP messages not being marked read
by void372＠transientvoid.com 30 Dec '10

30 Dec '10

I recently moved from Fedora 13 to Fedora 14 and consequently to dovecot 2.0.8. Since then, I have observed that messages are not being marked as read in all cases. The general behavior is: 1. Use my mail client to read all unseen messages. All mail folders show no messages unread. 2. Tell mail client to check for new mail. 3. Mail client now says that some folders have new mail (1 or more messages) 4. Clicking on a folder with new mail (say with 6 unread) shows that there are no unread messages. I have observed this behavior using both kmail and squirrelmail so do not believe it is a mail client problem. I have maildir folders to which mail is delivered using procmail recipes directly to the appropriate dovecot folder. In these folders, I notice that the "cur" directory has a matching number of messages that do not have an "S" flag on the end of the file name. For example: # ls .fedora-list/ cur/ dovecot.index.log new/ dovecot.index.cache dovecot-uidlist tmp/ # ls .fedora-list/cur 1293379204.26554_1.nehalem.home.rainbowdreams.com:2,S 1293379206.26571_1.nehalem.home.rainbowdreams.com:2, 1293379207.26581_1.nehalem.home.rainbowdreams.com:2, 1293380106.26744_1.nehalem.home.rainbowdreams.com:2, 1293380106.26748_1.nehalem.home.rainbowdreams.com:2,S 1293381904.26876_1.nehalem.home.rainbowdreams.com:2,S 1293383704.26978_1.nehalem.home.rainbowdreams.com:2,S 1293384604.27005_1.nehalem.home.rainbowdreams.com:2,S 1293385504.27067_1.nehalem.home.rainbowdreams.com:2,S 1293386404.27105_1.nehalem.home.rainbowdreams.com:2,S 1293387305.27158_1.nehalem.home.rainbowdreams.com:2, 1293387305.27166_1.nehalem.home.rainbowdreams.com:2, 1293388204.27193_1.nehalem.home.rainbowdreams.com:2, 1293389105.27234_1.nehalem.home.rainbowdreams.com:2,S 1293390005.27292_1.nehalem.home.rainbowdreams.com:2,S 1293390006.27298_1.nehalem.home.rainbowdreams.com:2,S 1293392706.27400_1.nehalem.home.rainbowdreams.com:2,S 1293392706.27406_1.nehalem.home.rainbowdreams.com:2,S 1293393611.27515_1.nehalem.home.rainbowdreams.com:2,S 1293396304.27673_1.nehalem.home.rainbowdreams.com:2,S 1293396305.27675_1.nehalem.home.rainbowdreams.com:2,S 1293398104.27743_1.nehalem.home.rainbowdreams.com:2,S 1293399003.27966_1.nehalem.home.rainbowdreams.com:2,S I have so far been unable to observe a pattern as to which messages get affected. I made the assumption that perhaps the issue is a conversion issue in my existing maildir folders, but this does not appear to be the case. When I moved the existing directory out of the way and started with a fresh empty directory the issue has come back after a day or two. Unfortunately, my install of Fedora 14 overlaid the partition with Fedora 13, so I cannot confirm the version of dovecot I was using with no issues. (so very glad I use separate disk and partition for the OS!) I can say that all configuration was in one dovecot.conf file, not the multiple conf.d files I see on Fedora 14. Any assistance on what to troubleshoot next is greatly appreciated! The info about my dovecot is shown below. The maildir's are on local LVM/RAID and not remote.

[Dovecot] Dovecot consulting companies
by Timo Sirainen 30 Dec '10

30 Dec '10

Once in a while someone asks about companies who could help installing / running / etc. their mail server. I don't really know many, so I thought I'd add a wiki page about it. Feel free to add your company on the list if you offer some Dovecot related services. Write also a few words what type of services you offer. http://wiki2.dovecot.org/Consulting I'll add a link there once at least one company is listed. :) Oh and if it's not clear above, I don't mean that the list should contain companies that only offer email accounts (Dovecot or not).

[Dovecot] Reverting from 2.0. to 1.2
by Thomas Hummel 30 Dec '10

30 Dec '10

Hello Timo, I switched this morning from dovecot-1.2.12 to 2.0.8 with a basic setup (high performance login mode, Maildir, everyhing on NFS, one shared but unused namespace). No problem so far except that some Thunderbird users who wouldn't succeed in moving messages from some one folder to another. They'd get a message about some illegal character in the mailboxname (already existing mailbox of course). This is user input so I don't have any details nor sufficient element to consider it a real problem. A Thunderbird restart seems to solve the problem. My questions were : . is there a different handling in the hierarchy separator (internal or advertized for the namespace) ? (I use "/" for both namespaces and "." since in Maildir). . is there a different handling in the non-ASCII mailbox names ? Could it be related ? . if something goes really wrong, is it safe to revert to 1.2.12 ? Maybe some files has non-compatible format (dovecot-uidlist, indexes, ...) ? Thanks. -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] Dovecot 1.2.12+Postfix+Active Directory: virtual domain name dropped.
by Ran Talbott 30 Dec '10

30 Dec '10

I have a Windoze-only client who wants to move their mail hosting from godaddy.com hosting to an in-house system. I'm pitching Linux as an alternative to Exchange, and trying to set up a demonstration system for them. While a long-time Linux user, my server admin experience has been in setting up front-ends (mostly Apache-based web interfaces) for the embedded systems I specialize in. The goal is to have an IMAP server where the users don't have Linux IDs, and only need to manually login to the Active Directory domain controller. The client has multiple Internet domains, but all users are in the same Active Directory realm internally. With the help of the how-tos at linuxmail.info, I got the system to the point of being able to authenticate logins for both IMAP and SMTP (usng dovecot-SASL). I tried using PAM first, but it didn't work: running kinit from the command line takes over 90 seconds to get a ticket, and Dovecot timed out after 60 on every login attempt. So I switched to LDAP. Note: I still don't understand why, but authentication through Active Directory didn't work until I changed the querying distinguished name from the "cn=,dc=,dc=" format to "user(a)xxxx.local" format. I have Postfix using dovecot-deliver as the LDA, but I hit a snag: deliver is not putting the domain name in the path to the maildir. I have the active directory query set as: user_filter = (&(objectClass=user)(samaccountname=%n)) user_attrs = =home=/var/mailstore/%d/%n. =uid=501, =gid=501, \ =mail=maildir:/var/mailstore/%d/%n/Maildir/ When I send mail to testing.testing(a)xxxx.xxx (real domain obscured), I see this in mail.log Dec 23 10:49:24 IBMUBUNTU1 dovecot: auth(default): master in: USER#0111#011testing.testing(a)xxxx.xxx#011service=deliver Dec 23 10:49:24 IBMUBUNTU1 dovecot: auth(default): ldap(testing.testing): user search: base=dc=lawley, dc=local scope=subtree filter=(&(objectClass=user) (samaccountname=testing.testing)) fields= Dec 23 10:49:24 IBMUBUNTU1 dovecot: auth(default): ldap(testing.testing): result: objectClass(?unknown?)= cn(?unknown?)= sn(?unknown?)= givenName(?unknown?)= distinguishedName(?unknown?)= instanceType(?unknown?)= whenCreated(?unknown?)= whenChanged(?unknown?)= displayName(?unknown?)= uSNCreated(?unknown?)= uSNChanged(?unknown?)= name(?unknown?)= objectGUID(?unknown?)= userAccountControl(?unknown?)= primaryGroupID(?unknown?)= objectSid(?unknown?)= sAMAccountName(?unknown?)= sAMAccountType(?unknown?)= userPrincipalName(?unknown?)= objectCategory(?unknown?)= Dec 23 10:49:24 IBMUBUNTU1 dovecot: auth(default): master out: USER#0111#011testing.testing#011home=/var/mailstore//testing.testing. =uid=501#011gid=501#011mail=maildir:/var/mailstore//testing.testing/Maildir/ i.e., the domain does not appear in the paths to the home directory or maildir. I found a bug report in the mailing list that looks like it might be the same problem (%d not supported in user_attrs), but the fix it references is for 2.0. Is this a known problem in 1.x? Is there a fix/workaround for it? E.g., could I have Postfix generate the maidir path and pass it to deliver as the "-m" parameter? Thanks, Ran

[Dovecot] Is this really a user agent issue?
by Phil Howard 30 Dec '10

30 Dec '10

I suspect this is a user agent issue, given that Evolution is flaky in so many areas. When I deliver mail to a subfolder/subbox (e.g. the -m option in the deliver command), and Evolution doesn't know of it, yet, creating it fails, and Evolution still can't get to it. Doing things the other way around (create it in Evolution first, then deliver to it) works fine. Seems to be silliness to me. Just wondered if any Dovecot aspects might be involved ... such as the fact that the case is different (e.g. "INBOX" in the filesystem, but "Inbox" in Evolution). -- sHiFt HaPpEnS!

[Dovecot] How to get a working dovecot.conf?
by oddball56 29 Dec '10

29 Dec '10

Hi, I installed openSUSE 11.3 server version, and followed the guidelines from: http://www.howtoforge.com/perfect-server-opensuse-11.3-x86_64-ispconfig-3 Everything works, accept loggin into dovecot. For many days i tried to get logged into dovecot, from localhost, from other pc in the lan, from squirrelmail, not possible. I read manuals on http://wiki.dovecot.org/ and tried to set the passwd db like: auth default { .. passdb passwd-file { args = /etc/passwd.dovecot } .. The "args" were not accepted according to the output from dovecot -n As now i installed dovecot 20, with a fresh dovecot.conf. Ofcourse this was not working, so i 'updated' ISPConfig. Now my dovecot.conf is a mess, and i get errormessages like: Dec 20 21:00:02 AsusTT-sfn6 postfix/smtpd[7073]: fatal: no SASL authentication mechanisms And from dovecot: dovecot.pem missing from /etc/ssl/certs, so no ssl login possible also Now i am checking dovecot -n line by line and this message pops out: mail_plugin_dir: access(/usr/lib/dovecot/modules/imap) failed: No such file or directory passdb { driver = pam } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } furtheron: ssl = no userdb { driver = passwd } userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } it has 64 lines. first and last_valid_uid and gid are set to 5000. In this conf i did not change anything. I would realy appreciate some help, as my only goal was to set up an imap server so i can access my mail from all over the world, and have all mail in 'one' central place, instead of scattered all over many pc's and laptops. The irony is that evrything but this works ;-p tia, for an answer.

[Dovecot] director in large(ish) environments
by Cor Bosman 28 Dec '10

28 Dec '10

Hey all, just wondering who here is running the director service in a larger environment. I just switched our whole production setup to the director and am quite pleased with the result. We're doing a peak of about 25000 tot 30000 concurrent sessions on 3 servers. But ive shut 1 server down a couple of days ago to see what would happen and 2 servers carried the load easily. (16 CPU, 24GB memory servers). If others are using the director on larger setups maybe we can all post when things do or dont work well. Now to see if the solution is better than the problem :) Cor

[Dovecot] Migrate from Maildir to mdbox
by Odhiambo Washington 28 Dec '10

28 Dec '10

Looking at http://wiki2.dovecot.org/Migration/MailFormat, I do not see much on how to do a migration from Maildir to mdbox. That page isn't quite updated it looks. I have several domains (virtual) with the following storage layout: /var/spool/virtual/$domain. So the users have their mail stored as follows: /var/spool/virtual/domain1/$user/Maildir /var/spool/virtual/domain2/$user/Maildir /var/spool/virtual/domain3/$user/Maildir /var/spool/virtual/domainN/$user/Maildir >From the wiki, I am told the steps to take are: 1. Set mail_location=mdbox:~/mdbox 2. Run "doveadm mirror -u username maildir:~/Maildir" The instruction above confuses me because in my situation, I don't have a "username" per se. dovecot-deliver knows how to figure out my usernames and their mail_location settings. How do I derive my "username" when users are virtual, stored in MySQL back end? Again, the right command seems to rely on dsync, not "doveadm mirror". I could manually get all the values for the users for each domain and run: dysnc -u $u -o "mail_location=maildir:/var/spool/virtual/domain1/$u/Maildir" mirror "mdbox:/var/spool/virtual/domain1/$u/mdbox" This is so manual, especially because I have to (if I remember well) create /var/spool/virtual/domain1/$u/mdbox (and have the permissions right) before running dysnc. Is there an easier way out, perhaps?? -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Damn!!

[Dovecot] passwd, gid and uid
by Mauricio Tavares 25 Dec '10

25 Dec '10

I forgot the answer for this: in http://wiki.dovecot.org/AuthDatabase/PasswdFile, we have the passwd file defined as user:password:uid:gid:(gecos):home:(shell):extra_fields What should the uid and gid be associated with? In my setup I told postfix to use Dovecot LDA's deliver, which then is saving files as uid:gid of 1500:1500. How would that affect the uid:gid used in the passwd file? From what I read in the dovecot's wiki, you want them *not* to be anything that has the rights to access the emails. So, does that mean any value for them will do?

[Dovecot] Maildir feature I'd like to see - SSD for newer messages
by Marc Perkel 24 Dec '10

24 Dec '10

SSD drives are very fast but expensive. So I have a crude idea that I'd like to see. May not be practical but would like to get some thoughts on it. Some new SSDs use SATA 3 (6gb/sec) with 355/mb/sec read speeds and 215MB/sec write. Put these in raid 0 and it screams! Can you imagine how fast that would be? What would be nice is if new email were on faster drives with old email being migrated to larger mechanical cheaper storage. Perhaps messages over a month old? From dovecot's perspective it would sort of all look the same but maybe one a week a script would run migrating older messages to slower media. It would also make backups easier. The faster newer messages could be archived hourly. On the weekend after the archiving script was run the older message could be backed up once a week. I'm not sure what it would take to make dovecot seamlessly access email from two different locations or if this is practical. Just wanted to throw the idea out there to see if something sticks.

[Dovecot] Is this an index problem?
by Chris Barnes 23 Dec '10

23 Dec '10

This is my first post to this list/gmane newsgroup, so please be gentle with me.... :-) Here's my situation: I have a user (the "main boss secretary") who uses MS Outlook 2007 as her email client. She has over 46,000 messages in her inbox, with nobody knows how many more in 75+ different folders & subfolders. Surprisingly, her response time wasn't too terrible up until we had to reboot our mail server the other day (actually, restoring the entire server from a backup). Now it takes anywhere from 10 to 60 seconds for her to switch from 1 folder to another. Details: * Server is Debian running Postfix and Dovecot (both the current release). Using Maildir format stored in the user's ~/Maildir folder. * User connects to server via Imaps. Connection is local using gigabit network (ie. it ain't the network). * Yes, we did all the things on the Outlook side -thinking that is where the problem lays. Rebuild the .pst file, had Outlook re-index, compacted the .pst file, etc. So now I'm thinking that maybe I need to just wipe out all of the ~/Mailder/dovecot* files (including all those in sub-directories) and let it all reindex. Which begets 3 questions: (1) will this help? (2) anyone have a shell script that will remove all those dovecot* files from the user's directory AND all the sub-directories? (3) Any other suggestions I might be missing? -- Chris Barnes

[Dovecot] Deliver limit based of number of destination recipients and size of mails, any option to do that?
by Andrés Yacopino 23 Dec '10

23 Dec '10

I have a mail server with postfix, dovecot (1.2.15) and deliver lda (dovecot) with 350 users. I have the problem that in this christmas the employees are sending some big files (mainly powerpoints files) to a lot of recipients, because of that the server get a lot of charge (is a Xeon quad core 5405 with 4GB of Ram), i have four disks in Raid 5 configuration (HP E200 controller, not very fast) Is there any option to limit this type of delivery, the total size of the mails delivered to each user (total recipients * size of mail), in dovecot deliver. I don't want to limit the concurrent delivery more lower than 350 recipients and the max size of the mail we can send is 15M. Thanks a lot, -- Andrés Fernando Yacopino

[Dovecot] trying to make cmusieve happen globally
by Phil Howard 22 Dec '10

22 Dec '10

In Dovecot 1.1.11 cmusieve is apparently integrated in the Ubuntu 9.10 package "dovecot-common" since the files are there. I am wanting to right now just do a very basic test of the setup to see how it runs before doing more sophisticated steps that could obscure any errors or bugs (e.g. unit testing). So I took the following example sieve script from the wiki1 documentation: require "fileinto"; if header :contains "X-Spam-Flag" "YES" { fileinto "spam"; } and recoded it to skip the test and just always do the fileinto step like so: require "fileinto"; fileinto "spamtest"; Then I configured my dovecot.conf file (via dovecot-postfix.conf it really points to) by setting: protocol lda { ... mail_plugins = cmusieve mail_plugin_dir = /usr/lib/dovecot/modules/lda ... } and: plugin { sieve_global_path = /etc/dovecot/sieve-global.d/spam.sieve } I manually compiled /etc/dovecot/sieve-global.d/spam.sieve so there also exists /etc/dovecot/sieve-global.d/spam.sievec in the same directory. Then I restarted both Dovecot and Postfix. Mail is being delivered, but still only to the same place it always has. The filesystem shows these sieve files are not being accessed at all. I've read documents http://wiki1.dovecot.org/LDA/Sieve and http://wiki1.dovecot.org/LDA/Sieve/CMU to come up with this. But it just doesn't seem to be happening. So I guess it is a good thing I've broken my testing down into smaller units. Anything standout that I misinterpreted about the documentation? If not, I can post the whole config files (in case there is a conflict with something else I have done). FYI, I'm only trying to do a global sieve, not per-user sieve scripts. I'll tackle per-user stuff at a later date, after the global is working. -- sHiFt HaPpEnS!

[Dovecot] Per user quota on MySQL
by M. Rodrigo Monteiro 22 Dec '10

22 Dec '10

Hi! I'm new on Dovecot. I'm using: - CentOS 5.5 - Kernel 2.6.18-194.26.1.el5 x86_64 - Dovecot 2.0.8 (from source) - Postfix 2.7.2 (from source) - MySQL 5.0.77 (CentOS binary) - Postfixadmin 2.3.2 (from source) - Horde Webmail 1.2.9 - Thunderbird 3.1.7 (from CentOS) I follow this how to: http://wiki2.dovecot.org/HowTo/DovecotLDAPostfixAdminMySQL I was able to send and recieve e-mail via Postfix/Dovecot. I'm having troubles in the quota. As I said, I use Postfixadmin to manage users. When I log in Horde, it says that the quota is unlimited. Thunderbird too. I think it's because of the configuration on Dovecot. Here it's my confs files: ===== dovecot.conf ===== #ssl_cert_file = /etc/pki/dovecot/certs/myserver.example.com.crt #ssl_key_file = /etc/pki/dovecot/private/myserver.example.com.key #ssl_ca_file = /etc/pki/dovecot/certs/ca-bundle.crt #default_login_user = nobody disable_plaintext_auth = no log_path = /var/log/dovecot.log auth_mechanisms = plain login first_valid_uid = 200 last_valid_uid = 200 mail_location = maildir:/var/vmail/%d/%u ssl = no passdb { args = /usr/local/dovecot/etc/dovecot/sql.conf driver = sql } plugin { #acl = vfile:/usr/local/dovecot/etc/dovecot/acls quota = maildir:storage=10240:messages=1000 trash = /usr/local/dovecot/etc/dovecot/trash.conf } service auth { unix_listener auth-userdb { group = vmail mode = 0660 user = vmail } unix_listener auth-master { group = vmail mode = 0660 user = vmail } unix_listener /var/spool/postfix/private/auth { group = vmail mode = 0660 user = postfix } user = dovecot } userdb { args = /usr/local/dovecot/etc/dovecot/sql.conf driver = sql } userdb { driver = prefetch } protocol imap { imap_client_workarounds = delay-newmail mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { mail_plugins = quota postmaster_address = postmaster(a)mydomain.com #log_path = /var/log/dovecot.log #info_log_path = /var/log/dovecot.log } ===== ===== sql.conf ===== driver = mysql connect = host=localhost dbname=postfix user=dovecot password=password user_query = SELECT concat('/var/vmail/', maildir) as home, concat('maildir:/var/vmail/', maildir) as mail, 200 AS uid, 200 AS gid, concat('maildir:storage=', floor(quota/1024)) AS quota FROM mailbox WHERE username = '%u' AND active = '1' ===== ===== mysql ===== mysql> select * from mailbox; +----------------------+------------------------------------+--------------+-----------------------+---------+------------+----------------+---------------------+---------------------+--------+ | username | password | name | maildir | quota | local_part | domain | created | modified | active | +----------------------+------------------------------------+--------------+-----------------------+---------+------------+----------------+---------------------+---------------------+--------+ | teste(a)mydomain.com | $1$bb3d6a71$IF/FORTbdoIqdzBLuSciJ0 | E-mail Teste | mydomain.com/teste/ | 1024000 | teste | mydomain.com | 2010-12-17 10:32:16 | 2010-12-17 11:46:24 | 1 | +----------------------+------------------------------------+--------------+-----------------------+---------+------------+----------------+---------------------+---------------------+--------+ ===== ===== mysql_virtual_mailbox_limit_maps.cf ===== user = postfix password = password hosts = localhost dbname = postfix query = SELECT quota FROM mailbox WHERE username='%s' AND active = '1' ===== I think it's it.

[Dovecot] Managesieve with multiple uid's

Hi, I'm trying to setup a system with dovecot to remove the old courier one, and everything (pop3, imap, lmtp, quotas) but managesieve is working fine.

In this system when I try to connect to the managesieve port using telnet I get no response: $ telnet localhost 4190 Trying 127.0.0.1... Connected to localhost.localdomain (127.0.0.1).

[Dovecot] Restarting dovecot-auth stops authentication
by Attila Nagy 22 Dec '10

22 Dec '10

Hi, The Dovecot wiki states that Dovecot's master restarts all died processes, which is good for availability. But when I kill dovecot/auth (to simulate an error condition which happened on a machine), the authentication fails with: Nov 16 14:32:40 be dovecot: imap: Error: net_connect_unix(auth-master) failed: No such file or directory It seems -albeit it gets restarted- dovecot/auth doesn't re-create its socket file. Before: # ls /var/run/dovecot/ anvil auth-worker doveadm-server anvil-auth-penalty config dovecot.conf auth-client dict empty auth-login director-admin lmtp auth-master director-userdb login auth-userdb dns-client master.pid # ps auwx | grep dovecot/auth dovecot 87455 0.0 0.0 20024 3832 ?? S 2:34PM 0:00.01 dovecot/auth # rm /var/run/dovecot/auth-master; kill 87455 # ps auwx | grep dovecot/auth dovecot 88815 0.0 0.0 20024 3776 ?? S 2:36PM 0:00.01 dovecot/auth # ls /var/run/dovecot/ anvil config dovecot.conf anvil-auth-penalty dict empty auth-client director-admin lmtp auth-login director-userdb login auth-userdb dns-client master.pid auth-worker doveadm-server I've deleted the auth-master socket because if I don't, you can't see that it's not re-created. :) Is this a normal behaviour? I understand that killing dovecot/auth is not, but Dovecot could survive this easily, if recreating and re-using the new socket file would work. And loosing dovecot/auth happens sometimes (I don't yet now why). Thanks,

[Dovecot] Moving email between folders outside of IMAP context
by Phil Howard 22 Dec '10

22 Dec '10

I'd like to run a script from cron that will scan certain mailboxes and move selected mail from one folder (usually INBOX) to another folder. The basic idea is to move previously detected spam based on headers prepended to the mail. Since I am not able to figure out how to get Postfix to invoke deliver with the -m option in these cases, and not in others, this is one idea I have come up with to deal with it. The big (hopefully obvious) complication seems to be getting the indexes updated. Is there a way to move mail this way AND then have the indexes updated to reflect that move (maybe even if regenerating the entire index all over again)? -- sHiFt HaPpEnS!

[Dovecot] Maildir and Solaris UFS acls
by Tom Lieuallen 21 Dec '10

21 Dec '10

I have a centrally located shared imap folder location. We have several maildir folders with different file system permissions. They are for several groups of people who are loosely related for support purposes. All mail gets delivered to queue1 just fine. The files are group writable by group1. Some of the mail gets moved via imap to queue2. Queue2's maildir tree is configured with Solaris UFS acls such that any new files are read/write by group1 or group2. If a new file is created within queue2 anywhere, it has the correct permissions. However, if a message is moved from queue1 to queue2, it retains the permissions that it had within queue1. This is what happens if I use 'mv' within the file system, btw. Is there any way to configure dovecot such that if a person moves or copies a message to another imap folder, it creates a new file instead of doing a link or mv or whatever? If not, no problem; I was just hoping for an elegant solution to my particular problem. :-) queue1 - read/write by group1 queue2 - read/write by group1 & group2 through solaris ACLs BTW, if any file whatsoever in queue2 is not readable by group2, those in group2 cannot read _anything_ in queue2. thanks Tom Lieuallen

Hello, Is there a way to have a Sieve script create a non-existent folder rather than have it deliver messages to INBOX instead? I'm using Dovecot 2.0.8 with Postfix, via LMTP. Thanks!

[Dovecot] Best way to move mail to an archive
by Richard C. Cox 19 Dec '10

19 Dec '10

Hello all...new to dovecot and this list. I have a question that may have been answered before, but I can't find anything yet that addresses it directly. I installed dovecot 2.0.8 (+postfix, fetchmail) on a small server to manage several e-mail accounts. I love this software! So, to back to the question: I'd like to archive e-mail as it ages into a single IMAP archive directory. Ideally, I would like to set up a cron job to search for e-mail in all of my imap directories that older that 'X' days and move it to the archive directory. I know that dovecot wants to manage e-mail movement thru the IMAP interface, so I'm leery of just using ordinary Linux commands to move mail around and bypass the IMAP protocol. Does anybody have any recommendations about dovecot/IMAP safe commands I could use to accomplish this task? Thanks in advance and I apologize for not being more knowledgeable about this subject. Regards, Richard

[Dovecot] Problem with expunge
by Jeff Mitchell 18 Dec '10

18 Dec '10

I'm running Dovecot 2.0.8. The other day I tested doveadm expunge on a test Inbox with a few messages received over the course of a day, and using savedbefore <a few hours>, and it seemed to work. However, today I was testing converting some maildirs over to sdbox, and noticed odd behavior: it's deleting all messages in the specified folder instead of just the ones matching the condition I'm using ("savedbefore 4w"). The command I'm using is "doveadm -Dv expunge -A mailbox Trash savedbefore 4w" Because of the conversion, all of the ctimes for all of the files are actually the same (basically, a few minutes ago), due to the converstion to sdbox from maildir, so I would expect that either it doesn't delete any of them or looks inside at some header of the mail (half of which was received/placed into Trash before 4w ago and half of which wasn't). I definitely don't expect full-on deletion... Any idea what's going on? Thanks, Jeff

Hi, after deciding to use Dovecot 2.0.8 as a postfix LDA using mysql DB I'm running into some issues. I started to follow, http://wiki.dovecot.org/HowTo/DovecotLDAPostfixAdminMySQL but noticed that the auth settings on the config changed, after looking through the dovecot wiki I think I have that issue fixed.

[Dovecot] namespace and list=children inconsistencies
by Holger Mauermann 17 Dec '10

17 Dec '10

Hi, after setting up a new Dovecot server with shared and public namespaces, both with hidden=no and list=children, I see some inconsistency in the folder listing. . NAMESPACE * NAMESPACE (("" "/")) (("Shared/" "/")) (("Public/" "/")) . OK Namespace completed. . LIST "" * * LIST (\HasNoChildren) "/" "INBOX" * LIST (\Noselect \HasChildren) "/" "Shared/user(a)do.main" * LIST (\HasNoChildren) "/" "Shared/user(a)do.main/INBOX" * LIST (\HasChildren) "/" "Public" . OK List completed. . LIST "Shared/" * * LIST (\Noselect \HasChildren) "/" "Shared/user(a)do.main" . OK List completed. . LIST "Public/" * . OK List completed. With LIST "Shared/" the other users INBOX is missing, so with namespace capable clients like Thunderbird it is impossible to see or subscribe this folder. The "Public/" namespace has some subfolders, but only for other acl_groups and I don't have rights to access any of them. So the LIST "Public/" looks good. However, with LIST "" * it is shown without the trailing slash and with \HasChildren where it should be hidden. Here is the relevant doveconf -n output: ... namespace { list = children location = maildir:%%h/Maildir:INDEX=~/shared/%%u prefix = Shared/%%u/ separator = / subscriptions = no type = shared } namespace { list = children location = cydir:/var/spool/imap/public:INDEX=~/public prefix = Public/ separator = / subscriptions = no type = public } ...

[Dovecot] How to avoid "authenticated user not found" - messages when using multiple Ldap userdbs/passdbs?
by Sebastian Urbanneck 16 Dec '10

16 Dec '10

Following: We've got a Dovecot 1.0.10 running on Ubuntu Hardy. Till now we used to have only mail accounts under our own domain, but since we're also a webhoster the people began to ask if there is a possibility to use there own Domains in there mail address. For addressing this we changed our Ldap Tree Structur: users which had been there befor remain in there old subtree, new accounts for Virtual Domains are located below an "vd=<domain>,ou=domains,..." subtree. The main Problem at this: old users are used to login only with their username and password, new users has to login via their complete mail address and their password. This is not going to change in the future so I tried to do this: Using two userdb/passdb - entries, in each case one for the old users and one for the new ones. If a user is not found through the first request the second is tried. If this failed too, the user gets rejected. The Problem with this: when not found during the first try the request logs an "authenticated user ot found" - message, no matter if trying via the second etry is successful. Is there a way to tell dovecot, that the user is not "not found" until __both__ requests failed? Regards Sebastian

[Dovecot] adding servers to director_mail_servers
by Cor Bosman 16 Dec '10

16 Dec '10

Is there a specific order in which one has to add servers to director_mail_servers, Let's say I have 20 loadbalanced director servers (I dont, but for arguments sake). I want to add 5 servers to director_mail_servers. If I do this by restarting each director server 1 by 1 with an updated conf, it seems the 5 new servers dont get added. Or at least I dont get what makes it work eventually. Only after restarting a few times they seem to all want to agree on the new list of servers. Cor

[Dovecot] users's mailboxes = mbox , shared mailboxes = maildir ... is it possible ?
by Frank Bonnet 16 Dec '10

16 Dec '10

Hello I solved my previous SSL problem by reinstalling dovecot2 ... :-) at FreeBSD 8.1 Now I'm using dovecot 2 , cool ... Actually my production mail server runs with MBOX format but reading the dovecot 2 wiki I read shared mailboxes are only working well with Maildir format. As I would like to setup some shared mailboxes, is it possible to have MBOX format for normal users ( UNIX NIS users ) and Maildir format for shared mailboxes to gain access to the per-user \Seen flag Or do I have to convert ALL my server to Maildir format ? Thanks a lot for your help

Hello, What the subject says. I am trying, that is. OK, here's the story. Users very lazy. Don't want to write down their contact details from scratch. Here's what I thought : migrate (export?) contacts from outlook to mozilla thunderbird. Then find a way to make thunderbird "talk" to dovecot, so that the latter can import the contact details from mozilla tb. Any ideas ? Will it work ?

Regarding Dovecot 1.2.x, for maildir, I believe it would be something like this: mail_location = maildir:~/Maildir:INDEX=MEMORY The ":INDEX=MEMORY" disables writing the index files to disk, and as the name implies, I believe, simply keeps indexes in memory. The docs say: "If you really want to, you can also disable the index files completely by appending :INDEX=MEMORY." My read of that is that indexing isn't disabled completely, merely storing the indexes to disk is disables. The indexes are still built and maintained in memory. Timo, is that correct? Also, due to the potential size of the index files (mine alone are 276 MB on an 877 MB mbox), you'll need to do some additional research to see if this is a possibility for you. If using a ramdisk, 100 mail boxen like mine would require ~ 27.6 GB or RAM just for the index files. This would not be logical to do or feasible given the amount of RAM required. I don't know if, or how much, storing them in RAM via :INDEX=MEMORY consumes, as compared to using a ramdisk. The memory consumption may be less or it may be more. Timo should be able to answer this, and give a recommendation as to whether this is even a sane thing to do. -- Stan

[Dovecot] question about snarf plugin in dovecot 2
by Tom Lieuallen 15 Dec '10

15 Dec '10

I'm trying to get the snarf plugin working with dovecot 2.0.7. Specifically, I want to use the UW-IMAP style optional snarfing. I'm looking at the wiki2 documentation. The first question is whether the UW-IMAP optional snarfing will require any changes to the mail_location. The first section suggests (but doesn't specifically state, which I'd propose be clarified) that mail_location be updated to point at ~/mbox for INBOX. However, with the optional snarfing, sometimes inbox will be at /var/mail and for some users, it'll be ~/mbox. What, if anything, do I do to mail_location? Does it matter where (in which config file) the plugin block is placed? I put all of my snarf configuration in 10-mail.conf. It's not working; not snarfing and not reading mail from ~/mbox (how would it, I have yet to tell it to). The following are excerpts from 10-mail.conf mail_location = mbox:~/mail:INBOX=/var/mail/%u:INDEX=/a2/imap-index/%u .... namespace { type = private separator = / prefix = inbox = yes } .... namespace snarf { prefix = /snarf separator = / location = mbox:/private/dovecot/var/run/dovecot/empty:INBOX=/var/mail/%u:INDEX=MEMORY list = no hidden = yes } plugin { snarf = /snarf/INBOX mbox_snarf = ~/mbox } Thank you BTW, the dovecot-2.0.7/docs/wiki appear to be from wiki1, not wiki2... :-) Tom Lieuallen Oregon State University

[Dovecot] After-delivery sieve processing
by Daniel L. Miller 14 Dec '10

14 Dec '10

Is it possible to run sieve against an existing mailbox? My application: I've got a mailbox that stores status messages from multiple sites. It's easier to check up on recent events by having them all in one folder. However, after I've read them, I'd like to have them archived to individual folders per site. I currently have a sieve script that uses "fileinto" to sort the mails - but I'm thinking of removing it from deliver if I can run it as a manual job later. I suppose another method would be to duplicate the mails on delivery into both the main folder and the per site folders, then delete after I've read them - but for whatever reason that strikes me as inelegant. -- Daniel

[Dovecot] Migration from UW-IMAP
by Daniel Senie 14 Dec '10

14 Dec '10

I am attempting to test out dovecot on a server on a separate IP address from the live, functioning UW-IMAP. I am having mixed results with dovecot. An entirely new account that's never been used with UW-IMAP seems to work fine, but that's really not the point of the exercise. If I try changing over an existing account to use dovecot, I get a variety of issues. Testing with Apple Mail.app, if I synchronize the account, the INBOX stops displaying. So off to plan B, and debug via command line commands. I tried connecting to Dovecot. It was able to list the mailboxes for me. I asked for status on INBOX. Sometimes I get an error back in the IMAP stream, sometimes not. Either way, the log shows complaints about creating mail/.imap and below (we use mbox format, plus /var/mail/%u for inbox). I have active namespace compatibility recommended by the Wiki so that clients specifying "mail/" and clients not specifying an imap path both work. With the test account, I proved this functionality is working. At this point I clearly have some issues, and could use some help figuring out what to ask for help with, i.e. how to proceed to debug this without damaging the existing UW-IMAP setup in the process. The goal is to cut over to dovecot once I can be sure it really is working compatibly, but until then I have a large user base and can't blow everything up. And yes, I really, truly have RTFM (i.e. read the Wiki, the troubleshooting pages, the migration pages).

[Dovecot] Incorrect W value after filesystem corruption
by Bob 14 Dec '10

14 Dec '10

Dec 14 00:15:54 vm dovecot: IMAP(####@####): Maildir filename has wrong W value: /var/vmail/#####/####/cur/#########.M###########.??.????.??.??,S=4951,W=5057:2,RSa Dear Dovecot elite, This morning I woke up to find my mail server hard disk controller had gone crazy and decided to corrupt my file system. After over eight passes with the fsck and a new machine I have mostly recovered but this being a personal server the backups were a half-job. So for speed I recovered the mail directly off the bad file system. Most of the data was fine but a few files were corrupt and as a result I have found Dovecot to be a real pain when it comes to handling a wrong W value. I am having to separately look at the mail.log and just systematically remove the W value as a quick work-around. But it seems to me that it would be much easier to have this done by Dovecot when it realises it has this wrong value, especially as Dovecot seems to drop the connection of that user after encountering this problem. Can I suggest as an improvement this scenario is handled better? I saw one posting which said "this should never happen" but clearly it can and I think there could be better handing of it perhaps?

[Dovecot] Courier-mta with Dovecot LDA
by komodo 14 Dec '10

14 Dec '10

Hi all I have setup dovecot lda instead of maildrop on my courier server. Delivery is working, sieve plugin too, but i can't figure out why lda can't send emails via sendmail (vacation). I always get error Error: Sendmail process terminated abnormally, exit status 67 And i know why, but i don't know how to setup lda to make it work . Here is .courier file where is redirect to lda. | /usr/libexec/dovecot/deliver -a $RECIPIENT -f $SENDER But the deliver does not pass recipient address to sendmail. Here is some output of strace execve("/usr/libexec/dovecot/deliver", ["/usr/libexec/dovecot/deliver", "-a", "komodo@somedomain", "-f", "someuser@somedomain"], [/* 22 vars */]) = 0 So it's clear that deliver have those variables, but then i can see this execve("/usr/sbin/sendmail", ["/usr/sbin/sendmail", "-i", "-f", "<>", "--", "someuser@somedomain"], [/* 2 vars */] <unfinished ...> And there is empty -f , so here is the problem. How should i setup this to make it work correctly ? Here is my config [root(a)OVZ.mail ~]# dovecot -n # 2.0.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-194.8.1.el5.028stab070.5 x86_64 CentOS release 5.5 (Final) disable_plaintext_auth = no hostname = ovzmail listen = 10.0.10.34 mail_location = maildir:~/Maildir 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 mbox_write_locks = fcntl namespace { inbox = yes location = prefix = INBOX. separator = . type = private } namespace { location = maildir:/home/shared/Maildir prefix = spam_learner. separator = . type = public } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap sieve ssl_cert = </etc/pki/dovecot/certs/server.pem ssl_key = </etc/pki/dovecot/private/server.pem userdb { driver = prefetch } protocol lda { mail_plugins = " sieve" } protocol imap { mail_max_userip_connections = 40 } Many thanks Martin

[Dovecot] FTS and compound searches
by Tony Pyro 13 Dec '10

13 Dec '10

Hello, New subscriber here. I noticed that the FTS index is not used in compound searches. Is this expected? Tested in 2.0.0 and 2.0.8: . search BODY "waldo" * SEARCH . OK Search completed (0.000 secs). . SEARCH CHARSET UTF-8 OR SUBJECT "waldo" FROM "waldo" * SEARCH . OK Search completed (1.768 secs). . SEARCH CHARSET UTF-8 OR SUBJECT "waldo" BODY "waldo" * OK Searched 0% of the mailbox, ETA 9605:25 * OK Searched 4% of the mailbox, ETA 6:39 * OK Searched 6% of the mailbox, ETA 6:58 * OK Searched 8% of the mailbox, ETA 6:54 It's a problem for us because the Afterlogic webmail client does not offer a body-only search. The two search options are From + To + Subject, or "entire messages", which puts together a large OR query: SRCH1069 SEARCH CHARSET UTF-8 OR (OR (OR FROM "waldo" TO "waldo") SUBJECT "waldo") BODY "waldo" I also checked to see whether the header fields are included in the FTS index but it didn't appear so. I got more results from the search "TO gmail.com" than from "BODY gmail.com" plugin { fts = squat } protocol imap { mail_plugins = " fts fts_squat" } Thanks!

I'm trying to set up SMTP authentication on my server and am getting an authentication failed error. My client is set up to automatically select authentication method and tries CRAM_MD5. The http://wiki.dovecot.org/HowTo/PostfixAndDovecotSASL suggests "passdb pam" and "userdb passwd" -- is it possible to configure sasl authentication using a dovecot.conf like http://pastebin.com/6JWE5jp1?

[Dovecot] Question about "slow" storage but fast cpus, plenty of ram and dovecot
by javierdemiguel＠us.es 13 Dec '10

13 Dec '10

Hello We are using dovecot 1.2.x. In our setup we will have 1200 concurrent imap users (maildirs) and we have 2xraid5 sas 15k diks mounted by iSCSI. The dovecot server (RHEL 5 x64) is a virtual machine in our vmware esx cluster. We want to minimize disk I/O, what config options should we use. We can "exchange" CPU & RAM to minimize disk i/o. Should we change to dovecot 2.0? Maybe mdbox can help us? Maybe ext4 instead of ext3? Any idea is welcome. Regards Javier

[Dovecot] Pigeonhole 0.2.2 - managesieve supports virtual namespaces?
by Tom Talpey 13 Dec '10

13 Dec '10

I got around to trying the 0.2.2 managesieve listener and it's not working for me. As soon as the client authenticates, the connection is closed and the following is logged on the server: > Dec 13 11:48:30 managesieve(xx(a)yy.com): Error: user xx(a)yy.com: Initialization failed: Namespace 'Mobile/': Unknown mail storage driver virtual > Dec 13 11:48:30 managesieve(xx(a)yy.com): Error: Invalid user settings. Refer to server log for more information. I do have such a virtual namespace defined in dovecot.conf, obviously, and it works fine with dovecot 2.0.8. Additionally, the sieve plugin is working fine for lda, dovecot's deliver is executing it perfectly. Do I need to add a setting or plugin to "protocol managesieve" for this? Combed the wiki to no avail.

[Dovecot] extra fields with "passwd" userdb
by Patrick McLean 13 Dec '10

13 Dec '10

Hi, I am planning a migration of ~600 accounts to mdbox (from maildir) and was hoping to do some initial testing of certain account. I am hoping to use extra fields to migrate certain accounts in advance for testing, and I can't find info on setting up extra fields with the "passwd" backend. Is this possible, or will I have to use another approach?

[Dovecot] Feature request
by Nikita Koshikov 13 Dec '10

13 Dec '10

Hello Timo, and all. Preface: From time to time we have problems with thunderbird. The problem is that mail client begin to sync users inbox (or other folder) and this process didn't stop. Last time we have this situation - our monitoring system shows unusual amount of imap traffic send to one of local hosts. This host was - terminal server and 20 users worked with their mailboxes that time. But normal 20 imap session can't fork that amount of traffic (5.2Gb). After measuring local thunderbird's cached mailboxes we find out that one user have local INBOX about 19Gb and size is rising. On server side - this mailbox was 89Mb. And after killing thunderbird in logs appear: Dec 10 17:35:53 IMAP(user@domain 192.168.2.92): Info: Disconnected: Logged out bytes=1133593/1175103 Dec 10 17:35:53 IMAP(user@domain 192.168.2.92): Info: Disconnected: Logged out bytes=15964/44364 Dec 10 17:35:53 IMAP(user@domain 192.168.2.92): Info: Disconnected: Logged out bytes=54758/944989 Dec 10 17:35:53 IMAP(user@domain 192.168.2.92): Info: Disconnected: Logged out bytes=6532/43930 Dec 10 17:35:53 IMAP(domain@domain 192.168.2.92): Info: Connection closed bytes=235408/4797272694 As you can see - 4.8Gb of data was send to this client - and who knows - what was that. So we have 5.2Gb send to host with 20 active sessions and 4.8Gb send to one user. Of course lifetime of this connection can be much more than last day, but problem disappeared after killing it. This is not single accident. But this one was hard to find out because of 20-25 users working at the same time from 1 server. So it will be great if dovecot has feature to limit the amount of data send per connection. For example: service imap { bytes_per_connection = 100Mb } And after limit reached - close connection and log warning. This will much simplify fights with sometimes become crazy imap clients. That do you think?

[Dovecot] limit login concurencly from different ip

[Dovecot] Quota warning generated when crossing on both sides
by Harm van Tilborg 13 Dec '10

13 Dec '10

Hello everyone, I'm experimenting with the quota warning plugin. I have the following setting in Dovecot's general config: plugin { quota_warning = storage=75%% /var/www/contrib/doquotawarning.py 75 quota_warning2 = storage=90%% /var/www/contrib/doquotawarning.py 90 } The doquotawarning.py script is working okay -- meaning that the user gets a warning. My SQL backend uses the following query: user_query = \ SELECT m.maildir AS home, 1001 AS uid, 1001 AS gid, \ CONCAT('*:bytes=', m.quota, 'M') AS quota_rule, \ 'Trash:ignore' AS quota_rule2 \ FROM mailbox m \ INNER JOIN domain d \ ON d.id = m.domainid \ WHERE d.domain = '%d' \ AND m.user = '%n' Where m.quota is the user's personal quota (in MB). As you can see, we ignore the 'Trash' box, when considering the usage data. We are using the dict quota backend. Now this is what happens. Assume we have 'user(a)example.org', that has a quota of 10MB and he currently has 5MB in use. Now someone sends a 3MB email towards 'user(a)example.org'. Dovecot does indeed generate the warning message (75%), that arrives correctly 'together' with the 3MB email. Now the user moves the 3MB email to trash. This goes well, however: Dovecot generates the 75% warning message again. Which is not necessary: the user was cleaning his mailbox, i.e. usage is 5MB again. I have the feeling Dovecot is generating the warning event twice. When getting from e.g. 50% to 79% and when the usage is lowered from 87% to 70%. I have the feeling this is either not the correct behavior, or I'm misinformed. When looking at the source, this shouldn't be happening: if ((bytes_before < (uint64_t)warnings[i].rule.bytes_limit && bytes_current >= (uint64_t)warnings[i].rule.bytes_limit) || (count_before < (uint64_t)warnings[i].rule.count_limit && count_current >= (uint64_t)warnings[i].rule.count_limit)) { quota_warning_execute(root, warnings[i].command); break; } We're using Dovecot 1.2.9 (Ubuntu's 10.04 LTS version). -- Kind regards, Harm van Tilborg

[Dovecot] Crash in 2.0.8 dovecot/imap - information capture
by Tom Talpey 13 Dec '10

13 Dec '10

My dovecot logs revealed a crash in the dovecot/imap process a few days ago. It appears to have dereferenced 0x00000004 in the storage shared lib. Unfortunately, I didn't get a core and I'm not sure how to reproduce it. Dovecot 2.0.8 on linux32. Two questions: 1) How can I be sure I get a core next time? I think it's because I run dovecot/imap under a mail uid and didn't have write permission to the cwd. Any way to verify that was it, and be sure it works? 2) What other settings would provide more info if it happens again? Thanks! dovecot.log excerpt: Dec 10 08:43:53 master: Error: service(imap): child 30862 killed with signal 11 (core dumps disabled) Dec 10 08:43:53 imap-login: Info: Login: user=<xx(a)yy.com>, method=PLAIN, rip=169.254.100.10, lip=169.254.100.100, mpid=2243 kernel dmesg: imap[30862]: segfault at 4 ip b772ecd2 sp bfc90f90 error 4 in libdovecot-storage.so.0.0.0[b76e9000+b8000] [~] # dovecot -n # 2.0.8: /etc/dovecot/dovecot.conf # OS: Linux 2.6.33.2 i686 ext4 (not sure of exact config at time of crash, will capture next)

Would it be ok to set director_user_expire to a very high value? Say 1 day? This would pretty much lock a user into a specific server right? What if I set it to 1 year? :) What happens when the server a user is locked into disappears (i remove it from the pool). Then a day later, I add the server again. Is the user now locked to the new server, or will he revert back to the old server? Cor

[Dovecot] Execute Script on LMTP Deliver?
by Edward Carraro 10 Dec '10

10 Dec '10

Is it possible to have dovecot 2.0.8 using LMTP run a shell script each time it delivers a message to a users mailbox? I see there's an "execute = script /path/to/script" but when i added it to lmtp service in 10-master.conf, it didnt do anything and stopped delivering mail altogether service lmtp { executable = script /usr/local/bin/test.sh u% unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix user = postfix } inet_listener lmtp { port = 24 } } $ ls -lh | grep test -rwxrwxrwx 1 root staff 270 2010-12-09 18:05 test.sh $ cat test.sh #!/bin/sh USER=$1 echo $USER > /tmp/newfile basically when a message arrives, it will execute a shellscript which will notify another service that mail has arrived in their inbox

[Dovecot] Phantom INBOX in 1.2. Is there a stable .deb of 2.0?
by ian+dovecot＠comtek.co.uk 10 Dec '10

10 Dec '10

Hi, We've been running 1.2 Dovecot for a while and are happy with it. In trying to migrate from symlinks to shared folders I see a similar problem to that shown at http://www.mail-archive.com/dovecot@dovecot.org/msg32083.html . For example: . lsub "" "*" * LSUB () "." "Users..INBOX" The advice given in the thread is to upgrade to 2.0. We currently use Debian's 1.2 package and I'm reluctant to move since I can't find a stable 2.0 .deb (http://wiki2.dovecot.org/PrebuiltBinaries only has repository heads of 2.0). Building from source is an option but I'd really prefer to be using a package. Can anybody advise on an appropriate way to go? Like the original poster I am seeing INBOX under the shared namespace when I try to share. I'm also getting an empty /var/mail/virtual/users/Maildir created (maildir:/var/mail/virtual/users/%n/Maildir/). We formerly had an INBOX prefix namespace from a Courier migration too, but it has been deleted (to no avail). Shared folders do work, though. It just requires 'anyone l' in /etc/dovecot/dovecot-acls/.DEFAULT (though I'd really rather not do this!). Thanks for any help, Ian ######## mail_location = maildir:/var/mail/virtual/users/%n/Maildir/ namespace private { separator = . prefix = inbox = yes } namespace shared { separator = . prefix = Users.%%n. location = maildir:/var/mail/virtual/users/%%n/Maildir/:INDEX=~/shared/%%u subscriptions = no list = children } namespace public { separator = . prefix = Shared. location = maildir:/var/mail/virtual/public:INDEX=~/public subscriptions = no } auth default { mechanisms = plain passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } passdb ldap { args = /etc/dovecot/dovecot-ldap-master.conf master=yes } userdb passwd { } userdb ldap { args = /etc/dovecot/dovecot-ldap-userdb.conf } userdb ldap { args = /etc/dovecot/dovecot-shared-ldap.conf } } plugin { acl = vfile:/etc/dovecot/dovecot-acls:cache_secs=3 acl_shared_dict = file:/var/mail/virtual/shared-mailboxes.db }

[Dovecot] Released Pigeonhole v0.2.2 for Dovecot v2.0.8
by Stephan Bosch 10 Dec '10

10 Dec '10

Hello Dovecot users, The new Dovecot v2.0.8 release has a few changes that prompted changes in Pigeonhole as well. This means that a new release of Pigeonhole is also necessary, because otherwise things will not compile anymore. Apart from a few rather minor bugfixes, some of which originate in Dovecot, one TODO item has finally been resolved: the reject action uses the LDA mail reject API, meaning that the associated LDA settings now also work for Pigeonhole, as would be expected. Changelog v0.2.2: * LDA Sieve plugin: started using Dovecot LDA reject API for the reject extension. This means that the LDA reject_reason and reject_subject settings now also work for Pigeonhole's LDA Sieve plugin. * Did some work on the new sieve-filter tool. It is mostly functional, but it is not finished yet. * Dovecot change: services' default vsz_limits weren't being enforced correctly in earlier v2.0 releases. Now that they are enforced, you might notice that the default limits are too low and you need to increase them. This problem will show up in logs as "out of memory" errors. See default_vsz_limit and service { vsz_limit } settings. - Imap4flags: fixed segfault bug occurring in multiscript context. - Added version checking to the ManageSieve settings plugin. This plugin was forgotten when the LDA plugin was updated with this change in the previous release. - LDA Sieve plugin: fixed memory leak at deinitialization. The release is available as follows: http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.2.tar.gz http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.2.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.0 wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] Dovecot as IMAP proxy to Exchange
by Hugo Monteiro 09 Dec '10

09 Dec '10

Hello list, I'm looking into the possibility to setup dovecot to act as an IMAP proxy to an Exchange server. Things i know beforehand: - I will not be able to use the ldap (Active Directory) user DN for auth binds (but i discovered that i could could use the user userPrincipalName attribute as bind DN. I tested it using ldapsearch and it worked fine.) - I will not be able to perform any unbinded searches. - The Exchange server is unique, so i can setup a static proxy route to the server. Given the above, i'd like to post some questions: 1 - Will i be able to use auth_bind = yes given the restrictions? My first guess is that this might work if i use something like "auth_bind_userdn = %u(a)example.org" 2 - Will i be able to specify a static route to the exchange server, not having to rely on that information from the AD itself? Another thing i'd like to know is if NTLM auth can be used while dovecot acts only as proxy. Thanks in advance, Hugo Monteiro. -- fct.unl.pt:~# cat .signature Hugo Monteiro Email : hugo.monteiro(a)fct.unl.pt Telefone : +351 212948300 Ext.15307 Web : http://hmonteiro.net Divisão de Informática Faculdade de Ciências e Tecnologia da Universidade Nova de Lisboa Quinta da Torre 2829-516 Caparica Portugal Telefone: +351 212948596 Fax: +351 212948548 www.fct.unl.pt apoio(a)fct.unl.pt fct.unl.pt:~# _

[Dovecot] Dovecot 1.2/2.0 coexistence guide?
by Tom Talpey 09 Dec '10

09 Dec '10

I am running Dovecot 1.2.16 and considering moving up to 2.0.8. I have found <http://wiki2.dovecot.org/Upgrading/2.0> but there's not a lot about deploying a 2.0 server alongside an existing 1.2. Any hints on a seamless approach to this, especially one that might allow me to upgrade individual users in place, without moving their maildirs into a new tree and still avoid issues with 1.2/2.0 sharing access?

[Dovecot] passdb pam and userdb passwd "Authentication failure" errors

While using Ubuntu 10.10 + Dovecot 1.2.12 + Postfix 2.7.1-1: To enable virtual accounts, I am using the following /etc/dovecot/auth.d/virtualsomename.auth file: passdb passwd-file { args = /etc/dovecot/passwd } userdb static { args = uid=vmail gid=vmail home=/home/vmail/%u } EOT cat /etc/dovecot/passwd looks like this: test:{PLAIN}pass bill:{PLAIN}secret timo@example.com:{PLAIN}hello123 dave@example.com:{PLAIN}world234 Issuing a 'sudo dovecot -n' shows: .../... auth default: verbose: yes debug: yes debug_passwords: yes passdb: driver: pam passdb: driver: passwd-file args: /etc/dovecot/passwd userdb: driver: passwd userdb: driver: static args: uid=vmail gid=vmail home=/home/vmail/%u .../... and while trying to connect to Dovecot as dave(a)example.com the log shows: 2010-12-04 18:15:58 auth(default): Info: new auth connection: pid=15334 2010-12-04 18:15:58 auth(default): Info: client in: AUTH 1 PLAIN service=smtp nologin lip=127.0.1.1 rip=127.0.1.1 resp=AGRhdmVAZXhhbXBsZS5jb20Ad29ybGQyMzQ= 2010-12-04 18:15:58 auth-worker(default): Info: pam(dave(a)example.com,127.0.1.1): lookup service=dovecot 2010-12-04 18:15:58 auth-worker(default): Info: pam(dave(a)example.com,127.0.1.1): #1/1 style=1 msg=Password: 2010-12-04 18:16:00 auth-worker(default): Info: pam(dave(a)example.com,127.0.1.1): pam_authenticate() failed: Authentication failure (password mismatch?)

[Dovecot] How to handle "Waiting for authentication process..."
by A.L.E.C 08 Dec '10

08 Dec '10

Sometimes, when dovecot authentication processes are busy, dovecot write reply "Waiting for authentication process to respond.." to client. Roundcube webmail do not understand it and invalidate user session. My question is what is a good practise to handle this situation by client software? One Roundcube user proposes to detect such response then wait a moment and try again. Is there any standard for this? How long should we wait?

[Dovecot] local seen flags with shared mailboxes
by Tim Mauerbach 08 Dec '10

08 Dec '10

Hello all, after recent upgrade from 2.0.5 to 2.0.8 it seems that local seen flags for mails reside in shared mailboxes doesn´t work anymore. Before the upgrade I had read mails with account #1. Account #2 (who has access via acl) saw the mails still as unread. Now, no matter who read the mails, the other account see the same flags, immediately. I read the related wiki pages again and tried to find any configuration error, unfortunately without much success. I´ve attached output from "doveconf -n" and a debug logfile. Thanks a lot! Tim

As I mentioned in another post, your log message clearly shows the IPv6 address is being used. And yes, your host obviously is capable of that. You don't need to specifically enable it with fetchmail. It will under certain circumstances default to IPv6, which in your case happened. As also mentioned, your postfix seems to not bind to the IPv6 address by default, though, or it has deliberately been disabled. Moreover, your router is not even in the picture here -- just like dovecot, FWIW. Fetchmail fetches the mail from a remote server, and tries to deliver it locally. That local delivery step is generating the log messages. A mail, sent from and to your box. Long after the data stream passed your router...

[Dovecot] proxy and gpg processing
by Mike 07 Dec '10

07 Dec '10

Hi I have dovecot running as pure proxy for accessing imap and pop mailboxes on other servers. How can I do the following scenario: When a client user reads a gpg signed or gpg encrypted email through the proxy, can I verify/decrypt the email before it gets delivered to the client user? Ideally I would like to write a perl program which processes the email within the proxy before it gets delivered to the user. With Sieve I can not do this, is there another way to achieve this? Thanks for any hint. Mike
