[Dovecot] IMAP ACLs not working
by Seba 18 Mar '09

18 Mar '09

Hi, I've some problems to get folder ACLs working with Dovecot. I've defined some folders (like drafts, spam etc.) for every user and created a dovecot-acl file in every folder so that users can not delete or rename these folders but this does not work as expected. Config ===== Debian Lenny 5.0 Dovecot 1.0.15 dovecot.conf ========= protocols = imap protocol imap { listen = xxx.xxx.xxx.xxx } disable_plaintext_auth = yes log_timestamp = "%Y-%m-%d %H:%M:%S " ssl_disable = yes mail_location = maildir:/home/vmail/%Ld/%Ln namespace private { separator = . prefix = inbox = yes } mail_privileged_group = vmail protocol imap { mail_plugins = acl } protocol lda { postmaster_address = postmaster(a)example.com hostname = hostname(a)example.com mail_plugins = cmusieve } auth_username_translation = %Lu auth default { mechanisms = cram-md5 passdb pam { } passdb sql { args = /etc/dovecot/dovecot-sql.conf } userdb passwd { } userdb static { args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes } user = root socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = vmail } client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } Folder structure =========== (For dovecot-acl) /home/vmail/example.com/user/.Spam/dovecot-acl dovecot-acl contains =============== owner lrwstiek For me the config looks OK and I can't find an error... When I change the dovecot-acl to "owner l" for example it seems that this change has no effect. Are there an error in my setup? Seba

[Dovecot] mbox on NFS + automount, folder creation -> mkdir_parents() failed
by Sebastian Kayser 18 Mar '09

18 Mar '09

Hi, i am about to migrate some internal imapd mboxes to dovecot. Regular access is fine, just when i want to create a folder i get the following error message in the logs: Mar 18 17:36:57 pulsar dovecot: [ID 107833 mail.error] IMAP(skayser): mkdir_parents(/home/skayser) failed: Operation not applicable /home/skayser is mounted via autofs. When i set mail_location to a subdirectory within /home/skayser, folder creation works. From looking at the truss output dovecot tries to mkdir() the parent and doesn't seem to like the ENOSYS that is returned when the directoy is an autofs mountpoint.

[Dovecot] NFS-error with dovecot 1.1.12
by Martin Preen 18 Mar '09

18 Mar '09

Hello, I'm testing version 1.1.12 and occasionally there is Mar 18 14:40:44 imap2 dovecot: [ID 107833 mail.error] IMAP(xyz): nfs_flush_file_handle_cache_dir: rmdir(/home/xyz) failed: Device busy It seems that it is related to a crash of the previous imap process of that user. And it doesn't seem to cause any problems. So can it safely be ignored ? It is on Solaris 10. Index storage is local (UFS) and mailbox storage is NFS (mail_nfs_storage=yes).

Uhg, I win the CluelessnUnobservant Award for this. Thanks everyone for the followups. I caught that myself yesterday and fixed the problem on Postfix's side. To sum up in case anyone else runs in to this, the mistake I made was in assuming that Postfix just made the handoff to Dovecot and that Dovecot would handle the rest, so I commented out the parts of the old config where Postfix handled this when I was using Postfix virtual transport. Once I restored those and gave Postfix the query it needed, it worked fine. Thanks for bearing with me, everyone. Kat

Welcome, I'm new one here . I've switch to dovecot in order to get mysql auth to recive emails. And I am not sure about one thing : may I configure dovecot to user more then one DB to authorize users ? I have suse 11.1/postfix/mysql system where the users exist in 2 separate DBs. Delivering works well, I'm just not sure if everyone could revive the emails ? Any tips ? reagards, Sebastian

[Dovecot] Dovecot LDA and "undeliverable" emails

I googled around looking for this, apparantly my google-fu is failing this morning. I just switched over to using a Postfix/Dovecot virtual set-up with Dovecot as the delivery agent.

Timo wrote: > So Postfix delivers bounces to everyone by calling Dovecot LDA > separately for each bounce? Looks like a Postfix configuration problem > to me. I should have been more specific... because we'd also changed domain names at the time we moved over to using Dovecot as the LDA, I temporarily disabled automatically bouncing mail addressed to invalid users because I figured that we'd have at least one who decided that they didn't want the standard formation of email addresses... What I'd wanted to happen was for Postfix to accept the message(s) and then for them to be delivered to the postmaster address so that I could address the issue. I'm still unsure as to why, when Dovecot couldn't find the user in the tables, it copied the message to every user of the system - that seems like odd behavior, which indicates that even though the system is "working", I need to fine-tune something.

[Dovecot] Dovecot as a POP3-/POP3SSL-proxy in front of exchange 2003
by south africa 17 Mar '09

17 Mar '09

Dear all, im looking for a solution to protect an Exchange 2003 email server from direct "pop3-internet-connects". Is it possible that Dovecot act as a POP3-/POP3SSL-Proxy, "LDAP-authenticate" all user logins to a Windows 2003 domain controller and forward then all POP3-connects to a single Exchange 2003 server? Could someone give me some advices or a link for howtos for this solution? The howto on www.dovcot.org (http://wiki.dovecot.org/HowTo/ImapProxy) does not fit in my situation because it prefere a mysql server and not a LDAP-server/domain-controller.

[Dovecot] Errors on mbox to Maildir conversion

I have Julian Fitzell's migrateuser.sh script which uses mb2md-3.20.pl to convert a mailbox in mbox format to Maildir. I have set up a test user called "mailtest" which has mail as follows: /var/mail/mailtest /home/mailtest/mail/ Drafts MoreStuff Sent Items Stuff After the conversion I want all this user's mail to be in /home/mailtest/Maildir/ I'm not quite sure how to run the migrateuser.sh script, but I think it's like this (run as user mailtest): $ /usr/local/bin/mb2md/migrateuser.sh mailtest /home/mailtest /home/mailtest/Maildir When I run this I get the following output: mailtest -- Migrating INBOX...

by Harry Lachanas 16 Mar '09

16 Mar '09

Hi, I am on dovecot 1.1.11 trying to figure out the expire tool .... The thing is that when I had confed the exp tool there where a bunch of mails inside the mail boxes. Thus it seems as if the database is not updated about them. Is there a way to update it from command line to include the old mails ??? Thanks Harry

[Dovecot] folders are not under INBOX
by Ondrej Svoboda 16 Mar '09

16 Mar '09

hi guys, I hope it's common trouble, but I'm not able to find a solution: - i'am using courier imap and trying to migrate to the dovecot - on courier I have all folders as subfolder of Inbox - i.e. Inbox.Sent but on dovecot the folder Sent is not subfolder of Inbox, but its on the same level. Please is there some possibility to have the subfolders the same behaviour as in courier? we have lot's of customers so after the upgrade the folders can't change. thank you ondrej

[Dovecot] Dovecot and high availability
by d dimov 16 Mar '09

16 Mar '09

Hello dear all. Please accept apologies if the topic was discussed already, tried searching the archives but found few details. What I am looking for would be the best way to making Dovecot highly available in an environment where: two Alteons are load-balancing two Dovecot servers, each Alteon seing both of them; the clients are using exclusively POP3; low volume; in case of a Dovecot server failure service should fail over to the other node with preferably no manual intervention. Failover could mean Alteons just ignoring the failed host and routing all requests to the healthy one. Would it be shared NFS volume mounted on both of the servers from some NAS, maildirs put on that volume and both Dovecots seing the mailboxes simultaneously? Any risks? Is there a good document describing such a setup? Thank you in advance and please indicate if I missed relevant details. Best regards, Dimov

The only symptom is the log messages. The client sees nothing unusual, at least in this case where the session is a retrieval of one large message. I haven't tried long sessions retrieving multiple messages. If I remove pop3_lock_session = yes, the issue does not occur. I don't think I need it. I put it in a long time ago to attempt to solve a problem that was actually caused by something else. Since removing it does seem to avoid this issue, I will leave it out, but I'm reporting this anyway as it seems there may be some underlying problem. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

[Dovecot] pop-proxy to redundant servers ?
by Jan-Frode Myklebust 15 Mar '09

15 Mar '09

I'm considering putting two servers with failover IP-addresses in front of our pop/imap cluster, with dovecot in proxy-mode running on both servers. But, can dovecot handle more than one backend server for each user ? I.e. I would want to point the dovecot proxy to send userX to backend-server1, or backend-server2 if backend-server1 is down. Is something like that possible ? -jf

Changes in v1.2.beta2 since beta1: * Authentication userdb: Renamed system_user to system_groups_user. Probably pretty much no one used this feature. * deliver no longer creates temp files to /tmp. They're instead created to the users' mailbox directories. - IMAP: Fixed SORT command crashing - POP3 was broken in beta1 - Fixes to virtual mailboxes - Fixes to IMAP ACL support Changes in both v1.1.12 and v1.2.beta2: * Added :MAILBOXDIR= to mail_location to specify the root dir for mailboxes. dbox users should migrate to ":MAILBOXDIR=mailboxes", because that's going to be the default in v1.2+. + Linux: Adding -D parameter to login_executable makes login processes dump core to login_dir if they crash. - IMAP: SELECT didn't always return first unseen message in reply - POP3: pop3_lock_session=yes didn't use mail_privileged_group while dotlocking. - mbox: Don't crash if >=8192 bytes long line begins with "From ". - Maildir: More fixes to handling over 26 keywords. - Several logging fixes and improvements - Fixed authentication caching with non-plaintext mechanisms when using a blocking passdb (e.g. MySQL) - Fixed DIGEST-MD5 authentication with user@domain style usernames.

[Dovecot] setting up both system password users AND virtual users
by Jim Pazarena 14 Mar '09

14 Mar '09

I'm afraid that I am a rookie at dovecot, and cannot seem to figure the configuration for a dual system & virtual setup. For now I am using POP3 ---only--- I've got the "system" working, but cannot figure out how to add the virtual system. The docs aren't quite clear enough for me to understand. The wiki example for dynamic passwd-file locations shows: mail_location = maildir:/home/%d/%n/Maildir userdb passwd-file etc etc I am using mbox, not maildir, AND I've already used mail_location for my system accounts with the following line: mail_location = mbox:~/mail/:INBOX=/mail/%u In the case of my virtual users, the mail is stored in INBOX=/mail/VIRTUAL/%d/%u and the password file is stored in /exim/etc/VIRTUAL/%d/passwd would someone kindly help me with this? thanks!

[Dovecot] New to list, got a quota question
by Vlad Sedov 14 Mar '09

14 Mar '09

Hello folks - I'm running dovecot on top of qmail/vpopmail/mysql, serving up about 2500 mailboxes. Everything is running very smooth and fast.... I recently upgraded dovecot to 1.1, so I'm trying to implement some extra features like IMAP quotas. I'm using the sql passdb, with the following config: driver = mysql connect = host=/var/lib/mysql/mysql.sock user=username password=password dbname=vpopmail default_pass_scheme = PLAIN password_query = SELECT CONCAT(pw_name, '@', pw_domain) AS user, pw_clear_passwd AS password FROM vpopmail WHERE pw_name = '%n' AND pw_domain = '%d' user_query = SELECT pw_dir as home, 508 AS uid, 503 AS gid FROM vpopmail WHERE pw_name = '%n' AND pw_domain = '%d' My vpopmail installation keeps the quota information in the mysql database (pw_shell field) instead of maildirsize. The quota is in maildir format, e.g. 400M or 50331648S. Unlimited quota is specified as NOQUOTA. The question is... Is it possible to make dovecot understand this format and get it directly from SQL (via user_query, for example) or would it be easier to reconfigure the vpopmail installation somehow to use maildirsize? Thanks! Vlad

[Dovecot] how to handle CA CRL updates with client certificate verification context ?
by Raphael PRECIGOUT 13 Mar '09

13 Mar '09

Hello, As far as I can read in the Dovecot SSL configuration wiki page, each CA cert must be followed by the related CA CRL in the client certificate verification context ("ssl_ca_file" setting). In my company we do have our own PKI and as soon as Client certificate is compromised we do revoke it and update the related CA's CRL. Does that mean that I have to issue a new "ssl_ca_file" file as soon as our issuing CA CRL is updated ? If yes, does someone has an idea on how to do so ? Is it then necessary to restart dovecot process (to take the "ssl_ca_file" file changes into account) ? Does Dovecot have a way to check the issuing CA CRL automatically ? (the CRL is published in DER format and is accessible though http, the URI is mentionned in the CRL Distribution points of the CA certificate) Thanks in advance for your help. Regards, Raphael

[Dovecot] Problem with sasl auth with postfix...
by Douglas M. Stanley 13 Mar '09

13 Mar '09

Hello list, I'm running into some problems, and I couldn't find any info about this anywhere on the net. I recently set up a new debian lenny machine, and used my notes from the last debian etch machine I set up, which basically is for postfix + dovecot for sasl auth. On my old etch box, in the dovecot.conf, in the auth default section, I have a socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } However, if I use the same config on my lenny setup, dovecot fails to start, and I see this in my logs: Mar 13 19:16:30 mailserver dovecot: Dovecot v1.0.15 starting up Mar 13 19:16:30 mailserver dovecot: auth(default): User doesn't exist: postfix Mar 13 19:16:30 mailserver dovecot: Auth process died too early - shutting down Mar 13 19:16:30 mailserver dovecot: child 4623 (auth) returned error 89 Now if I comment out the user and group lines, it works fine, but the socket is owned by root, and so I have to change the mode line so that it's world readable in order for postfix to use it. The version of dovecot in etch is: 1.0.rc15-2etch4 and the version in lenny is: 1.0.15-2.3 Any ideas why this might be happening? Did the syntax to do this change between those versions? Any input? I guess I don't mind leaving it world readable, but I wasted an entire morning trying everything to get it to work, so I guess I'm hoping some one atleast has an answer as to why it doesn't work. Thanks, Doug

[Dovecot] Using LDAP for Dovecot extra/regular fields
by Jack Stewart 13 Mar '09

13 Mar '09

Hi, We're moving to a dovecot proxy / server configuration in order to make sure that a users go to a specific server. If someone has used these LDAP for this, there are a few things that I wish to verify. Dovecot does not verify that type of the LDAP attribute, only that the returned value works. If a boolean is used for a yes/no field, then FALSE sets the field to no and TRUE sets the field to yes. If a multivalue attribute is used for a single value field, the last returned value for the LDAP lookup is used in that field (i.e. host will use the last value). If a string attribute is returned for a yes/no field and has any value, then the associated field is set to true. There is no automatic failover with the host field so if the remote host is down, the IMAP connection no longer works. I'm fairly sure of all of these except for the boolean. Now this is just due diligence. I don't know that turning on/off or switching LDAP attributes is the right way to go to handle failover but it might work for phased rollout. My feeling is the best configuration will be using a secondary IP address that has to be manually turned on for a host after a reboot or shutdown. This creates a poor mans "fencing". The secondary can either be brought up on another host or handled via a load balance with DSR/backup server. As a practical matter, it is probably worth setting sensible attributes for each field (i.e. numeric for host, boolean for proxy/proxy_maybe etc). Any interest in registering an LDAP object class for dovecot? ---Jack

[Dovecot] Maildir dirty syncs
by Timo Sirainen 13 Mar '09

13 Mar '09

http://dovecot.org/patches/1.1/maildir-dirty-syncs.diff This patch adds a new maildir_very_dirty_syncs setting. If set to "yes", Dovecot assumes it's the only one changing the cur/ directory (so other MDAs can add mails to new/ without problems). This makes it possible to avoid rescanning the cur/ directory all the time looking for filenames. It also looks like (in stress testing) it still scans the cur/ directory unneededly in some situations, but it shouldn't be common. Maybe I'll look into it some day to see why. I'd be interested in hearing how large performance benefits it gives, if any. If they're big I could consider adding it to v1.1.12. If they're pretty much irrelevant I probably won't even bother adding the code to v1.2. I guess you mainly see the performance benefits with large/huge mailboxes.

[Dovecot] General approach question - am I doing this the right way?
by Alan Bates 13 Mar '09

13 Mar '09

Quick outline of my current working setup: I'm running dovecot 1.0.5 as an IMAP mail server on my ubuntu home server, which i connect to with my phone and several other machines to check my mail etc. i use getmail to collect mail from my various pop accounts. getmail filters the mail using spamassassin via a Filter_external, before moving it to my Maildir on the home server. Then when I connect to the home server from my various machines, IMAP manages the status of all the mail, so unread messages are common etc. All works very nicely. However I'd like to fix a minor annoyance... ...Spamassassin marks mail as SPAM but the mail client has to do the job of moving it to the Junk folder. I'd like the mail to be filtered on the home server on receipt. Am I just making things really complicated for myself? Is there a simpler setup for what I'm trying to do?

[Dovecot] Extremely custom mailbox locations
by Steve Kemp 13 Mar '09

13 Mar '09

I'm in the position where I'd like to offer IMAP access to a collection of email accounts which are stored in a very odd manner. Files are stored as: /blah/$dd-$mm-$yy/$domain/1234/1234 For example: /reject/12-3-2009/cvsrepository.org/35199/35199639 There is a single file for each mail, which I guess technically probably counts as an mbox folder, but only just. I can handle the custom login requirements I have, but I see no obvious way to create a mailstore from this information unless I build up a parallel symlink farm, such as: /imap/cvsrepository.org/{new cur tmp} I suspect if I fill cur/ with symlinks to each of the individual messages things will mostly work out OK, but I wonder if that is the best solution, or if there is a slim chance that I could serve this hierarchy without the intermediate step?

[Dovecot] which architecture to use?
by GVG GVG 13 Mar '09

13 Mar '09

Dear List, Based on the following installed environment: - OpenBSD (latest version!) - PostgreSQL - dovecot with SSL would like to have a mail server which accepts system as well as virtual users and being able to connect to their mailboxes either via an MUA (Thunderbird etc.) or a web interface (squirrel mail?). When using the web interface, non registered users should be able to creat e-mail accounts which will be dovecot virtual users! Which components should I use? Thanks

[Dovecot] Sieve - Backtrace after deliver(brabax): Panic: file sieve-cmu.c: line 264 (part_save): assertion failed: (buf->used - 1 == part->body_size.physical_size)

Hello, It's my first mailserver I set up. Thanks to everybody who contributes to dovecot. Dovecot works great for me! One thing I want to get rid off is this traceback error using dovecot with sieve. Somebody can help on this? System: Ubuntu server 8.10 dovecot --version 1.1.4 I filter for keywords in mail body with sieve. Mail is stored at lokal harddrive.

[Dovecot] 1.1.12 release candidate
by Timo Sirainen 13 Mar '09

13 Mar '09

http://dovecot.org/tmp/dovecot-1.1.12.rc.tar.gz I would have already released 1.1.12, but it needed the MAILBOXDIR change described below, and I'm slightly worried that it might have broken some special setup. So please test first and I'll release in v1.1.12 then in a few days. * Added :MAILBOXDIR= to mail_location to specify the root dir for mailboxes. dbox users should migrate to ":MAILBOXDIR=mailboxes", because that's going to be the default in v1.2+. - IMAP: SELECT didn't always return first unseen message in reply - POP3: pop3_lock_session=yes didn't use mail_privileged_group while dotlocking. - mbox: Don't crash if >=8192 bytes long line begins with "From ". - Maildir: More fixes to handling over 26 keywords. - Several logging fixes and improvements - Fixed authentication caching with non-plaintext mechanisms when using a blocking passdb (e.g. MySQL) - Fixed DIGEST-MD5 authentication with user@domain style usernames.

[Dovecot] Imap logout message on Dovecot restart
by RutgerM 12 Mar '09

12 Mar '09

I'm trying to receive a "Disconnected" message in my logfile for the connected imap-clients when I restart dovecot. When you disconnect a client, you receive the following message in your log: Mar 12 21:45:55 mail dovecot: IMAP(mailbox(a)domain.com): Disconnected: Logged out bytes=7496/22441 When a IMAP client is connected and Dovecot is restarted, this message is not shown. This should be solvable by a script like this: #!/bin/sh unset LOG_TO_MASTER export USE_SYSLOG=1 exec /usr/lib/dovecot/imap But this logs the user that runs the script into the imap server and when I terminate this terminal I get a "Disconnected" message for the local linux user, which I don't need of course. Is there a way to get to what I want ? I want to log my IMAP statics for every day and I need to "disconnect" my imap clients for it in some way to receive the Disconnected message and count from there. Thanks.

[Dovecot] High load/corrupted indexes after moving mailboxes?
by Patrick A. Treptau 12 Mar '09

12 Mar '09

Hello, we're experiencing an odd issue after combining two vDisks used for mail storage into one big new LVM. We've done this in the past successfully and didn't experience a lot of problems. We stopped all services (dovecot/postfix) to ensure that mailbox contents (Maildir) will not be changed, rsynch'ed the mail to the new disks and restarted everything. When we restarted dovecot, we noticed a huge spike in load (average load in top and high cpu iowait) and isolated dovecot as the issue. At some point, the average load crept up to over 100 and crashed the server twice. However, over time the average load and cpu wait times went down slightly. I have noticed a spike in load after moving user's mail storage, but not like this. It almost looks like everyone is either re-indexing or re-caching their mail? Any help would be appreciated. We're on dovecot 0.99. -Pat

[Dovecot] migration from dovecot to dovecot on different servers without downtime (dovecot replication?)
by Pau Oliva 12 Mar '09

12 Mar '09

Hello, I have an imap server with huge Maildirs and several users running dovecot 1.0.13, I need to migrate all the imap accounts to a new box which runs dovecot 1.1.4. The requisite is that need to do it with no downtime or minimal downtime possible, and totally transparent for end users. I have tried IMAP<-->IMAP syncing using a master user in both servers and imapsync, however due to the huge Maildirs (some users have more than 10 years of mail) this tends to be quite slow and painful. Can I tar all the user's Maildir and move them from one box to the other, and then run imapsync again? which I assume that would be faster... or is there any better solution I am not aware of? (ie: I've seen some emails about dovecot replication on the list archives, but few details of how that should be configured). I'd appreciate any feedback or thoughts on this matter. Thank you. Cheers, Pau Oliva

[Dovecot] GUI/WUI for creating (common) sieve scripts?
by Roderick A. Anderson 11 Mar '09

11 Mar '09

Anyone aware of a Web User Interface or GUI to allow users to create simple/common-type sieve scripts? I found the sieve testing and have used it as I play; plus mangesieve (and Net:ManageSieve.pm) but want to allow users to build so some clicking and maybe a little typing and then end up with some filters. So before I go invent this wheel I'd like to know what others are doing? TIA, Rod --

[Dovecot] Error crosscompiling

Hi, I was trying to crosscompile dovecot, but I got some error: --with-notify=inotify don't work, as it try to run a test program to verify if inotify is supported in the building platform. Solved with --with-notify=dnotify. Ihmo, is more a hack than a solution. | checking whether posix_fallocate() works... configure: error: cannot run test program while cross compiling I can't find an a suitable option for this error. Again the problem is that configure can't run an executable for a different platform. It's possible to set a safe default?

[Dovecot] Random timeouts on mailboxes
by Bastien Semene 10 Mar '09

10 Mar '09

Hello, My dovecot server is currently having random issues when users want to acces their mailbox. When the issue is occuring there's a timeout. It's random because it happens more or less often and is not dependent on a user or the way their check the mailbox. The time during the problem occurs is random, sometimes it's less than a minute, sometimes it's some hours. When a user can't connect to its mailbox, he generally can receive its emails through his BlackBerry (it's just to illustrate the fact that it doesn't seem to be linked to an account). When this issue occurs they can't receive the headers from any folder (INBOX, custom, sent, ...) and can't read mails that headers are known by the mail client. When there's timeout, users can send emails (same jail and with an error when the client want to write a copy in the sentbox) and use the calendar server for example (on the same machine). Dovecot is running on a FreeBSD 7.0 32bits, 4GB RAM, Intel Xeon QuadCore @ 1.86 Ghz, and 3*500Gb SATA-2 RAID-5 disks. The box is hosting jails, and the mail jails ( imap + smtp, clamav + spamassassin ). The mail jails are new (since August 2008) but worked great since the beginning of this year. The server is hosting 122 accounts currently. My first thought was that there's an I/O issue, the disks are maybe too busy or there's paging that result in a timeout. I check it through vmstat an top commands but nothing appears, there's always some memory free (between 90-300 MB) and a very little paging, generally around 1MB. The fault are under a hundred and when, few times, it has more than a hundred (generally under 200) the next snapshot is under 100. I set the screen/line to refresh every 5 seconds. I shutdowned all jails not directly related to the mail service but the problem still occured. I also separated clamav and spamassassin from imap and smtp to a different box. After that I checked the dovecot config to lighten it, and ( only ) disabled fsync. I upgraded the RAM, added memory is used, but nothing changed. The human resources are constantly changing here, we were more before the problem started than now (around 10-15%), to illustrate the fact that I don't think it is linked to the number of users. I tried to recreate some accounts having the issue, but the problem appeared again. I upgraded Dovecot Friday to 1.1.11 from 1.1.7 (The installation was before 1.1.7, I did an upgrade some times ago). I used a command script to log Thunderbird's IMAP activity, everything is fine but there's no timestamp in the logs. So I'm only sure now this is not an erroneous packet/info sent problem. I watched the TB doc ( http://www.mozilla.org/projects/nspr/reference/html/prlog.html#25306 ) but there's no directive to put a timestamp for each line of log. The network is fine. I tried different configuration to be sure a device isn't doing something weird. Now, I don't know what to check to identify the issue. If anyone has any idea I didn't wrote here, or if I did erroneous interpretation(s) from the datas, I'll be glad to know. Regards, -- Bastien Semene Administrateur Réseau & Système

Re: [Dovecot] Random timeouts on mailboxes
by listacc＠gmx.de 09 Mar '09

09 Mar '09

Hi Bastien, just a little thought because I had an issue like this (but with cyrus): Where is your thunderbird installation stored? In my case, it was not locally but on some windows mapped drive, and so also the imap cache of thunderbird was on this drive. Because we have a lot of mails in our accounts, the cache was about 50-100MB for some users, and users with a lot mail accounts had very often timeouts. This was due to performance problems on our network storage. Sometimes it also works to delete thunderbird´s cache files. Then it has to download all the headers again (bad with bad performing network storage :-/), but it seems that these cache files get corrupted from time to time and this also produces timeouts. kind regards Andreas -- Computer Bild Tarifsieger!

[Dovecot] Using account alias as login
by Javier Amor García 09 Mar '09

09 Mar '09

Hello, I use dovecot with a LDAP backend for user account and aliases. The aliases are objects of the class couriermailalias. Some users would like to use the alias address as POP/IMAP login instead of the 'true' account. Is this possible?. I am using dovecot version 1.0,10, from ubuntu hardy packages. Thanks for any answer, Javier

[Dovecot] Dovecot and Pipermail integration
by Ricardo Ramirez 09 Mar '09

09 Mar '09

Hello, I have a standard Mailman/Pipermail install with mboxes at MM_HOME/archives/public/listname.mbox/listname.box What's the best way to export these via IMAP using Dovecot 1.0rc15 on Debian etch? I know I could make a namespace with MM_HOME/archives/public/ but that would result in half of the directories being exported (the ones containing the HTML archives) being unusable. I could also create another directory and symlink all the mboxes in there but that seems wrong. Preferably, I'd like to have something like a namespace with a mail location of MM_HOME/archives/public/*.mbox/ but that doesn't work with v1.0 Ricardo

[Dovecot] hwo can i have managesieve protocol and cmusieve plugin work at the same time

How can I have both sieve systems working, the cmusieve is for a global all user spam filter, and the managesieve is for one user only.

[Dovecot] system & virtual setup
by Jim Pazarena 07 Mar '09

07 Mar '09

No one replied to my original email, and I was hoping if I re-phrase my question I can get an answer. I would like dovecot to provide system email (located at /mail/%u with system password and /home/%u) and also virtual email (/u/mail/VIRTUAL/%d/%u with password found at /u/exim/etc/VIRTUAL/%d/passwd). NO home space, but I would consider /home/%d/%u This I think has something to do with namespace, but the docs are too vague for me to understand. Can anyone help me out? I would very much appreciate it. I would even consider PAYING someone to set me straight. I am looking to migrate away from vm-pop3d. initially with POP3 and ultimately into IMAP. Thanks!

[Dovecot] [patch] example configuration for expire seems broken
by Robert McQueen 06 Mar '09

06 Mar '09

The expire configuration in the example config file in 1.1.11 is broken: root@omega:/etc/dovecot# /etc/init.d/dovecot restart Restarting IMAP/POP3 mail server: dovecot Unknown dict module: db expire plugin: dict_init() failed Error: imap dump-capability process returned 89 Fatal: Invalid configuration in /etc/dovecot/dovecot.conf failed! It's inconsistent with the documentation at http://wiki.dovecot.org/Plugins/Expire, so I've made the attached patch to try and fix it. Note: I don't know if this new configuration is correct either, because its a new box and I've not got any mails old enough to cause the plugin to try and write anything, but at least I can start dovecot like this. :) Regards, Rob

[Dovecot] imap locking spool?
by Mark Hedges 05 Mar '09

05 Mar '09

How does IMAP lock the /var/spool/mail/user file? Here's my problem: I'm writing a script to expire old or oversize mail through a series of archive folders. I don't want to take the whole server down to do this, nor does it seem like I would have to lock the user out entirely if I can manage to emulate the locks correctly. I am able to lock /var/spool/mail/user (and ~user/mail/*) from procmail, dovecot popmail, and openwebmail using dotlocks. What do I do to prevent dovecot imap from writing the spool and various mbox files while my script is running? Just posix fcntl on the various files? I'm trying to use Mail::Box in perl which I'm having some problems with, corresponding with the developer, but if anyone has any easy way out I would appreciate the advice very much! Mark

[Dovecot] failed assertion in 1.1.8: istream.c: line 81
by Alan Ferrency 05 Mar '09

05 Mar '09

Hello, We're having a problem in Dovecot 1.1.8 with a failed assertion on certain mbox format mailboxes. It happens both with deliver when it attempts to delier to the mailbox, and with IMAP connections for the affected box (though I'm not sure what they're doing at the time). Mar 3 12:55:26 <snip> dovecot: Panic: IMAP(<snip>): file istream.c: line 81 (i_stream_read): assertion failed: (_stream->skip != _stream->pos) This is on FreeBSD 6.2, without any nfs. The IMAP client is Squirrel Mail, but as I said, the assertion occurs with deliver as well. Apparently, moving the inbox out of the way fixed the problem for a while, but then it came back. Clearing out the dovecot index files seemed not to have any effect. I have a core dump available for deliver; here's a backtrace: #0 0x282bbecb in kill () from /lib/libc.so.6 #1 0x282bbe68 in raise () from /lib/libc.so.6 #2 0x282bab78 in abort () from /lib/libc.so.6 #3 0x080b7ad8 in default_fatal_finish (type=LOG_TYPE_PANIC, status=0) at failures.c:150 #4 0x080b7dbb in i_syslog_fatal_handler (type=LOG_TYPE_PANIC, status=0, fmt=0x80ca9a0 "file %s: line %d (%s): assertion failed: (%s)", args=0xbfbfe2a4 "{\215\r\bQ") at failures.c:308 #5 0x080b7c37 in i_panic (format=0x80ca9a0 "file %s: line %d (%s): assertion failed: (%s)") at failures.c:197 #6 0x080bb8a1 in i_stream_read (stream=0x8102e28) at istream.c:93 #7 0x080bbd3d in i_stream_read_data (stream=0x8102e28, data_r=0xbfbfe350, size_r=0xbfbfe354, threshold=0) at istream.c:322 #8 0x0806d85b in istream_raw_mbox_get_body_size (stream=0x8102e28, expected_body_size=11013) at istream-raw-mbox.c:562 #9 0x080736dd in mbox_sync_do (sync_ctx=0xbfbfe640, flags=0) at mbox-sync.c:151 #10 0x08075700 in mbox_sync (mbox=0x8103028, flags=0) at mbox-sync.c:1833 #11 0x08070001 in mbox_save_init (_t=0x80f2980, flags=0, keywords=0x0, received_date=1236108538, timezone_offset=0, from_envelope=0x80e6100 "<snip>", input=0x80f6f28, dest_mail=0x8106028, ctx_r=0x0) at mbox-save.c:318 #12 0x282ee17f in quota_save_init (t=0x80f2980, flags=0, keywords=0x0, received_date=-1, timezone_offset=0, from_envelope=0x80e6100 "<snip>", input=0x80f6f28, dest_mail=0x8106028, ctx_r=0xbfbfe9f0) at quota-storage.c:236 #13 0x0808e36d in mailbox_save_init (t=0x5, flags=0, keywords=0x0, received_date=-1, timezone_offset=0, from_envelope=0x80e6100 "<snip>", input=0x80f6f28, dest_mail=0x8106028, ctx_r=0xbfbfe9f0) at mail-storage.c:726 #14 0x0808c34a in mail_storage_copy (t=0x80f2980, mail=0xbfbfe9f0, flags=0, keywords=0x0, dest_mail=0x8106028) at mail-copy.c:28 #15 0x282ee08a in quota_copy (t=0x80f2980, mail=0x80fd028, flags=0, keywords=0x0, dest_mail=0x8106028) at quota-storage.c:180 #16 0x080590a4 in deliver_save (namespaces=0x80f7028, storage_r=0xbfbfeb60, mailbox=0x80d0eeb "INBOX", mail=0x80fd028, flags=0, keywords=0x0) at deliver.c:237 #17 0x0805a90c in main (argc=5, argv=0xbfbfec14) at deliver.c:1093 Does anyone have any clues on how to debug this further? I wonder if the original bug reporter removed both the mailbox and the index files at the same time; the current explanation is less than satisfactory. Thanks, Alan Ferrency pair Networks, Inc.

[Dovecot] set \Seen flag on mail
by J.P. Trosclair 05 Mar '09

05 Mar '09

I'm looking for a way to set the \Seen flag on certain mail no matter what. Currently I'm using a global sieve script to do this. From what I've read, there is no way to enforce the global script if the user creates their own sieve script. More details: I have a postfix transport that along with sender_bcc_maps and recipient_bcc_maps uses deliver to create a read only archive of user's mail. The mail intended to be archived is stored in a per user imap folder called "Archives" that uses the ACL plugin to make the messages there read only. In addition to that, I want the mail marked as \Seen upon delivery so that user's who subscribe to the Arhives folder don't see new mail indications and what not when mail is delivered there. Is there a better way to set the \Seen flag other than the global sieve script since it can be overridden by the user? -- J.P. Trosclair

[Dovecot] tls and auth plain login
by Bradley Giesbrecht 04 Mar '09

04 Mar '09

Hello List, I want to allow plain text passwords only on ssl/tls. Is it possible to have: auth default { mechanisms = cram-md5 ntlm ...... } and then over-ride this when connection is ssl/tls to allow plain and login? I have tried adding "mechanisms = plain login cram-md5 ntlm" to "protocol imaps{}" as an example but I get an error that the protocol does not exist. I read somewhere today that dovecot enables plain automatically over secure connections (ssl/tls) but I'm not seeing it. Also, "auth default" suggests that "auth something_else" is possible. I'm probably just doing a poor job of research but I'm not finding the answers I'm seeking. Using postfix and lda. # openssl s_client -connect localhost:993 # a01 capability * CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS UIDPLUS LIST- EXTENDED I18NLEVEL=1 AUTH=CRAM-MD5 AUTH=NTLM a01 OK Capability completed.

[Dovecot] problems with dotlock
by Mark Hedges 04 Mar '09

04 Mar '09

I have to make dotlock work because this openwebmail thing only supports one of dotlock or flock, but procmail delivery does dotlock and fcntl. procmail correctly creates a dotlock file in /var/spool/mail/username.lock when delivering, I can watch this with `while :; do ls -la | grep lock; done`. It works fine when lock_method=fcntl, but no dotlock file shows up in /var/spool/mail. mbox_write_locks are working correctly with mbox_write_locks = dotlock fcntl, the dotlock file shows up in the user's mail directory. However, dotlocking /var/spool/mail doesn't work: $ ls -la /var/spool/mail total 44 drwxrwxr-x 2 root mail 4096 Feb 25 17:39 . $ grep mail_privileged_group /etc/mail/dovecot.conf mail_privileged_group = mail Feb 25 17:45:45 anubis dovecot: POP3(despam_test_anubis): Effective uid=511, gid=100 Feb 25 17:45:45 anubis dovecot: POP3(despam_test_anubis): mbox: data=/home/anubis/despam_test_anubis/mail:INBOX=/var/spool/mail/despam_test_anubis Feb 25 17:45:45 anubis dovecot: POP3(despam_test_anubis): mbox: root=/home/anubis/despam_test_anubis/mail, index=/home/anubis/despam_test_anubis/mail, inbox=/var/spool/mail/despam_test_anubis Feb 25 17:45:45 anubis dovecot: POP3(despam_test_anubis): file_lock_dotlock() failed with mbox file /var/spool/mail/despam_test_anubis: Permission denied Feb 25 17:45:45 anubis dovecot: POP3(despam_test_anubis): Couldn't open INBOX: Internal error occurred.

[Dovecot] GSSAPI cross-realm still broken
by Bryan Jacobs 03 Mar '09

03 Mar '09

I've been trying to track down some problems with Dovecot in a Kerberos 5 cross-realm environment, and there seem to be a few issues. LOGIN/PLAIN work fine using pam_krb5, but GSSAPI is a bit harder to handle. On line 436 of src/auth/mech-gssapi.c, the authn_name and the authz_name are compared using gss_compare_name. This dates back to the message at: http://dovecot.org/pipermail/dovecot/2005-October/009615.html While everything within that message is true, as things stand, Dovecot is unusable in a cross-realm environment. When cross-realm tickets are used, the authn_name is "username@REALM" and the authz_name is "username" (or vice versa, I don't remember). The attached patch causes dovecot to display these two values in human-readable format to illustrate the issue. Because these two GSS names differ, Dovecot refuses to allow access in spite of the fact that krb5_kuserok would return TRUE. I am not the only one to have noticed this problem: http://dovecot.org/pipermail/dovecot/2007-July/023868.html http://dovecot.org/pipermail/dovecot/2007-October/026027.html Might I suggest that some more robust security checking be done instead of abusing gss_compare_name like this? I don't know how to do this using GSSAPI, but on the Kerberos side Heimdal provides the function krb5_kuserok. Dovecot could also just have a configurable file listing acceptable krb5 principals (preferably in .k5login syntax) and check that both auth_name and authz_name are in the list. Bryan Jacobs

[Dovecot] Anyone know or have a perl, c/c++ script?
by Brandon Lamb 03 Mar '09

03 Mar '09

Hello all, Im hoping maybe someone on this list has already looked for or built something similiar. Basically from what I can tell, phps imap libraries or whatever dont support setting custom keywords. So I am wondering if someone has a library or script that can take a username, domain, password, folder, uid and flag to set so that my webmail app can call this to set imap keywords. So far my google searching isnt turning up anything, but searching for the word keyword doesnt really help.

[Dovecot] Seperate auth per protocol (pop3/imap)
by Guy 03 Mar '09

03 Mar '09

Hi, During discussions with the boss we've speculated about having users having only specific services available. One of the ideas was to have users being able to specify if they wanted POP3 or IMAP and whether we could limit their access to one or the other server side. We use MySQL for the userdb and passdb lookups at the moment. Is it possible to specify separate auth files with different MySQL lookups per protocol? Thanks Guy -- Don't just do something...sit there!

[Dovecot] dovecot imap and thunderbird tags
by Lorenzo Bettini 02 Mar '09

02 Mar '09

We've been using an imap(s) dovecot server for a while on an ubuntu 8.04.2 and we noted that tags set by thunderbird ("important", "to do", etc.) are almost always lost, i.e., when connecting to the same imap account from another machine, the tags are not there anymore... this always happens for the Inbox, and seldomly for other imap folders... anyone else experiencing this? Note that the same problem does not arise with other imap server accounts... thanks in advance Lorenzo -- Lorenzo Bettini, PhD in Computer Science, DI, Univ.

[Dovecot] Maildir format use question
by Rick Romero 02 Mar '09

02 Mar '09

Hey all, I've got a couple servers using Maildir format. As I understand it from a simple perspective, 'new' contains newly delivered messages, and 'cur' contains messages that have been 'handled'. I like to keep things simple for users, so rather than have 'Spam', 'Junk' 'ToLearn' and other possibly confusing folders, what I thought I would do is scan their .Spam/cur folder for mail that was older than an hour (based on file atime(?) stamp) and feed that through SpamAssassin. The idea being that anything in 'cur' would: 1. have been moved there by the user. 2. be recently read, and I think if it were innocent, would be handled within an hour 3. Not contain newly delivered, unread mail. This is actually what I see when I view my Spam folder through Evolution. If I use a PHP webclient - either Horde or Roundcube (I've captured the debugs if you'd like them), then a simple view of the Spam folder causes the files to be moved from new/ to cur/. They are updated with the :2, - but since nothing was actually done, no flags are added. So I'm left with a quandry. I guess the simple question is, Should mail in cur, EVER not have a flag? I suppose if it were marked as UNSEEN after being SEEN, that's possible. So I just answered myself there :) Is it possible to have Dovecot NOT move a file from new/ to cur/ until a flag has been assigned to the mail? Just from a, possible, performance standpoint - it seems when accessing an INBOX from a PHP webmail system with MANY new mails, there is an unnecessary(?) mass move of these files to another folder. Thoughts? Rick

But the sender also got an undeliverable email from the dovecot mailbox and a copy was not saved in the dovecot mailbox. I need emails forwarded, and a copy saved in the dovecot mailbox.

What options are available for remote storage, i.e. storage devices directly mounted on the machine running Dovecot? I've seen discussions of NFS usage - but my experiences with NFS in times past have been poor. CIFS has worked well for me for non-mail use - would this be suitable? Or is there another method I've not considered? -- Daniel

[Dovecot] Compilation Issue on Old Boxes with macro in src/master/main.c
by Kevin A. McGrail 28 Feb '09

28 Feb '09

I'm throwing an error compiling with a custom-compiled gcc 3.2.3 on one box. The configuration string is CC=/usr/local/gcc3.2.3/bin/gcc CPPFLAGS=-I/usr/local/ssl/include LDFLAGS=-L/usr/local/ssl/lib ./configure --with-ssl=openssl --with-ssldir=/usr/local/ssl/certs --with-pam --with-pop3d --sysconfdir=/etc --localstatedir=/var I've used this to compile on other older boxes with success. And I compared the command lines and they are identical. This is the error I get with src/master/main.c main.c:365:1: directives may not be used inside a macro argument main.c:364:16: unterminated argument list invoking macro "printf" main.c: In function `print_build_options': main.c:372: syntax error before string constant Changing the function to a simpler function without the ifdef's resolves the issue and dovecot compiles. I would really like to know why two boxes with the same compiler are failing on one but not the other. Perhaps there's some program or library or preprocessor or path or something out of whack. Especially since using gcc 2.96 on the same box works! However, I since this is a simple options output routine and (from my cursory read) there may be some standards issue with this technique, I've also patched the issue. http://www.peregrinehw.com/downloads/dovecot/dovecot-1.1.11-build_options_m… Thoughts?

[Dovecot] Custom flags in v1.0.15
by Pascal Mouret 28 Feb '09

28 Feb '09

Hello all, I'm having problems with setting custom flags on a dovecot imap setup, with mbox mail store. I was running v1.0rc15 on a Debian Etch box, upgraded recently to v1.0.15, but nothing changed. The problem : I read my mail using IMAP. In Thunderbird (various versions, current one being v2.0.0.19), I can set various message flags (Important, Personal, Work, ... mapped to IMAP as $Label4,$ $Label3, $Label2, ...). I read my mail from several machines, but all changes made on the message flags from one machine won't appear on the others !? Still I've read that those flags are supported in Dovecot. Actually, I logged the IMAP traffic, and saw that Dovecot claims to "handle" them. For instance, I added a flag to a message : Thunderbird > 621 uid store 35150 +FLAGS ($label4) Dovecot > * 6716 FETCH (UID 35150 FLAGS (\Seen \Recent $Label4)) Now, if I close TB, so that changes are written to the mbox file, and if I open that file on a the server with any text editor, the 'X-Keywords' line doesn't appear !? And as a matter of a fact, if I read my mail from any other machine, the flag isn't set ! Anyone knows where the problem can be ? Do I need to upgrade to v1.1 ? Or are custom flags actually supported in v1.0 (which I believe is the case) ? I browsed through the internet and searched the archives of this mailing list but didn't find any clue ... Any help would be much appreciated Thank you very much in advance Pascal Mouret -- Pascal Mouret Responsable du Service Informatique Polytech' Marseille, Université de Provence 60, rue Joliot-Curie / 13453 Marseille cedex 13 Mel : pascal.mouret(a)polytech.univ-mrs.fr Tel : 04 91 11 38 04 / Fax : 04 91 11 38 54

This: Feb 16 10:05:56 server dovecot: Panic: IMAP(user): file istream-tee.c: line 144 (i_stream_tee_read): assertion failed: (ret > 0) auth-worker died. That happened with Dovecot 1.1.4, 1.1.7 and 1.1.11, 1.1.7 was not with me, was with another user I found, on some mailing list. The problem occurred when copying or deleting messages, sometimes even viewing (Webmail). Since it's a production server, I compiled the latest 1.0.x and I'm using it. This particular server was running Ubuntu 8.04 (the default package is 1.0.x) and I upgraded to 8.10 (the default package is 1.1.x). > > > Is it possible to have Dovecot on one machine serving two different domains? > > Set up how? Do you want to use user@domain style usernames, or do you > want Dovecot to detect the domain based on the server's IP address? One dovecot server which receives mail to two domains and does not forward the mail anywhere, it's the final destination for the two of them. I already have usernames that are unique, by using Dovecot variables I have username~domain.org as the actual username/mailbox name. I want to have two mailbox roots, this way, even knowing that mailbox names are unique (john~domain.org != john~anotherdomain.org) and when authenticating (from what you wrote down here about passdb) john(a)domain.org will not be confused with john(a)anotherdomain.org, even so, I want all mailboxes from one domain to sit on a different mailbox root. > > > Is is possible to set a LDAP config to one domain and another > > LDAP config to the other (the auth part, I wan't users to reside > > on different bases on my LDAP tree, so search bases need to be > > different) > > Yes. You can just create two passdb ldap {}s. Ok, so, I have 3 aspects to consider: a) When mail arrives b) When user logs in to check mail c) Where mailboxes are located a) Since I can make mailbox names unique with Dovecot variables (mailbox name is "susan~domain.org" which is different from susan~anotherdomain.org) when mail arrives, the mail message will be saved to the correct mailbox (even if I have, under the same mailbox root, two users with "susan" as the login, but from different domains). b) Since you said, on Dovecot 1.0.x, I can have two passdb ldap{}'s, when the user logs in, he/she will be redirect to the right mailbox, not the "other susan". c) Ok, the two above give me the possibility to have all mailboxes, from the two domains, under the same mailbox root, users will be unique no matter the scenario (mail arriving, user checking mail), BUT, I would like to keep them separated anyways, is that possible to force that? > thanks! = Miata Convertible Tops Buy manufacturer direct from gahh, leader in high-quality convertible tops using original materials and attachments.

[Dovecot] Quota + Sieve
by Linux Advocate 27 Feb '09

27 Feb '09

Thanx to everybody's help , i have got a working combination of; - dovecot LDA - smtp auth thru dovecot sasl - postfix - virtual users in mysql - postfixadmin - thunderbird as the email client Just 2 additional questions - A. Sieve .............. With the imap filters in thunderbird, do i need to use sieve in dovecot? my initial observations/ findings say "no"? B. Quota ............. If i have not set quota in dovecot or postfix ( no quota related configuration ), may i then assume, the users have "unlimited storage" , limited only by the hardware/filesystem? I would like to have this feature ( just like unlimited storage in yahoo ) and just have a cron script running regularly to delete old emails ( for middle level, low level users ). Is such a strategy ok? regards, mgomez

From there it didn't take long to figure out that something had changed with update of Dovecot that no longer allowed this configuration line to work: mail_location: ~/Maildir and both in dovecot.conf and log I was warned to add the prefix "maildir"" With this everything seems to be fixed. I don't know whether this would be considered any kind of bug. The Debian package allowed me to upgrade Dovecot without warning me that the rules for mail_location had changed.

[Dovecot] internal raw storage - dovecot deliver in /tmp
by lejeczek 26 Feb '09

26 Feb '09

is it configurable anywhere on the runtime level, is it configurable at all selinux policy does not allow for transition between some domains that subsequently results in deliver not being granted permissions it needs to write to /tmp instead of compiling a policy module I wonder what is the matter with that raw storage and /tmp? cheers ___________________________________________________________ Try the all-new Yahoo!

[Dovecot] Quick question...
by dovecot＠segel.com 26 Feb '09

26 Feb '09

Hi, Here's the scenario. I want to set up a mailbox so that when mail sent to the address is piped to a processing application, instead of going to a mailbox. One way I can do this is to set up a mailbox and then have an application that checks to see if there's mail and then processes it. (Old school Unix script) Is there a way to set it up with dovecot? (Cleaner solution) Thx -Mike

[Dovecot] exim4 + dovecot + SquirrelMail virtualhosted on Debian
by Tim Legg 25 Feb '09

25 Feb '09

Hello, I have a Debian machine that is virtual-hosting 6 domains with exim4. I finally got exim4 working well enough where I can send and receive mail using the mail command on my machine. I would eventually like to have SquirrelMail (which requires IMAP) working on my website. For whatever reason, exim4 doesn't seem to support IMAP. I found out that Dovecot is a prominent IMAP server. So I installed the most current Dovecot package (1.0.rc15) in Debian. Something is broken though... As I log into SquirrelMail, I get an error message "Error connecting to IMAP server: localhost. 111 : Connection refused". To investigate, I decided to telnet localhost on port 143 and found out that yes, the connection is in fact refused. So what do I need to do in order to have dovecot listen on port 143? Also, I noticed when I restart dovecot... debian:/etc/dovecot# /etc/init.d/dovecot restart Restarting mail server: dovecotError: Can't use mail executable /usr/lib/dovecot/imap: No such file or directory I hope this isn't a serious problem. Thanks Tim Legg

[Dovecot] Securing mailboxes and passwords
by Daniel Aleksandersen 25 Feb '09

25 Feb '09

Hi list I am just experimenting with seting up my own email server. I want some tips and hints on how to secure my setup to prevent unauthorised assess to my email. I have read through the wiki and have not found many tips. I hope to improve the wiki with tips gathered from the emailing list. :-) A basic measurement I could take right now would be to set more secure file premissions on my setup. My setup is based on http://wiki.dovecot.org/HowTo/VirtualhostingWithExim with a few addittions: fetchmail and exim4 deliver mail to my maildir and dovecot grants me access through imap. dovecot authenticates against /home/postmaster/passwd.digest and ./passwd.cram -- Daniel Aleksandersen <aleksandersen(a)runbox.no>

[Dovecot] Calling dovecot deliver from procmail
by Harry Lachanas 25 Feb '09

25 Feb '09

I came up with this trick That is Since my previous mail server had a bunch of complex procmail recipies and I am not sure that I can turn them into sieve scripts I am calling dovecot deliver to drop mail in it's final $DEFAULT destination. :0 | /some/path/dovecot/deliver in order to update the index, control files etc upon delivery time. So far in my "tests" it works. But I wonder if this is wise or not. Regards, Harry.

[Dovecot] Dovecot problem after last Debian sid update

Hi All, After upgrading dovecot for sid Thunderbird no longer displays the contents of any emails I have had a working IMAP setup for as much as a year even though I don't understand dovecot configuration well enough to know how I got it to go in the first place. Here is the output of dovecot -n # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-1-vserver-686 i686 Debian 5.0 log_timestamp: %Y-%m-%d %H:%M:%S disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_location: ~/Maildir auth default: passdb: driver: passwd-file args: /etc/passwd.dovecot userdb: driver: passwd TIA for any clues as what to do next.

[Dovecot] OT: Fixing Messages To Be RFC 2822 Compliant
by Neil 25 Feb '09

25 Feb '09

So....apparently I have some messages which are not RFC compliant sitting in my mailboxes (mostly older ones), and I have some software which is refusing to handle such messages. 1. Does anyone know of a nice way to verify that all my messages are compliant/find those that aren't? (I suppose I could use the existing failing software, but I was hoping for something a little more robust...) 2. Does anyone know of any tools that will do The Right Thing as far as fixing these messages are concerned? Googling didn't turn up much for me, but maybe I wasn't hitting the right terms ("RFC message repair", "fix email message", etc.). Thanks.

24 Feb '09

I was thinking about all the old email I have and don't want to get rid of and how much space it is taking on my mail server. The idea came to me to install Dovecot on a server at home then I could drop mail into I want to save. It doesn't need to receive mail except what that is moved to it. Anyone see problems with doing this? Thanks, Rod --

[Dovecot] email stuck in outbox
by barnaby cockcroft 24 Feb '09

24 Feb '09

Can anyone here help me out with a client side Outlook issue? I know outlook is a horrible imap client :( We intermittently have a problem where mail gets "stuck" in Outlook users' outboxes. Might have anything to do with dovecot? Is there anyway I can troubleshoot this server side? Are there any settings I can tweak? We have a new and an old dovecot server (see below) and both exhibit the same behavior (occasionally) for heavy mail users. We haven't ruled out a layer 2 issue but nor have we found one.... If anyone has any ideas (other than suggesting a different email client), they'd be much appreciated. Dovecot version(s) 1.19 & 0.99.11 Configuration from 1.19: # 1.1.9: /usr/local/etc/dovecot.conf # OS: Linux 2.6.9-78.0.13.ELsmp i686 Red Hat Enterprise Linux ES release 4 (Nahant Update 7) ext3 syslog_facility: local0 ssl_cert_file: /usr/local/etc/ssl/**************** ssl_key_file: /usr/local/etc/ssl/***************** disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login mail_location: mbox:/home/%u/mail:INBOX=/var/spool/mail/%u mbox_write_locks: fcntl auth default: debug: yes passdb: driver: pam userdb: driver: passwd

[Dovecot] Broken dovecot-uidlist files
by Ulrich Zehl 24 Feb '09

24 Feb '09

I have just upgraded to 1.1.8, hoping to fix these types of errors: Jan 20 10:39:27 laura deliver(xxxxxx(a)example.net): Broken file /srv/storage/mail/store/net/example/xx/xxxxxx/Maildir/dovecot-uidlist line 156: Invalid data: Jan 20 10:41:19 laura dovecot: POP3(yy.yy(a)example.at): Broken file /srv/storage/mail/store/at/example/yy.yy/Maildir/dovecot-uidlist line 2: Invalid data: Unfortunately, they still pop up. Since I suspect these errors to be responsible for customers complaining about downloading mails twice, I'd like to fix them. Our setup has multiple servers sharing the same NFS-mounted directory for maildirs and indexes; we have set mmap_disable = yes dotlock_use_excl = yes fsync_disable = no mail_nfs_index = yes lock_method = fcntl As far as I can tell, for at least one of these errors, there was no concurrent access to the mailbox in question. What can I do to solve this problem, or to analyze it further? Ulrich

[Dovecot] Postfix LDA vs the Dovecot LDA + other quetions
by Linux Advocate 24 Feb '09

24 Feb '09

Guys , 1. What is the benefit of using Dovecot' LDA as compared to postfix's LDA? Will there be better performance? And along the same vein, 2. What is the benefit of using Dovecot's SASL as compared to Cyrus SASL? Is there better performance? 3. Quota Management ( Creating, enforcing, notifying ) - is it done thru dovecot or postfix or are both needed? Regards, mgomez

[Dovecot] pkgsrc-ing sieve and managesieve
by Edgar Fuß 24 Feb '09

24 Feb '09

I'm trying to integrate both the new sieve implementation and managesieve into pkgsrc. Managesieve seems to need some dovecot libraries that dovecot doesn't install (lib-storage/libstorage.a, lib-auth/libauth.a, lib-imap/libimap.a, lib-index/libindex.a, lib-mail/libmail.a, lib-charset/libcharset.a, lib-dict/libdict.a and lib-charset/libcharset.a). There seems to be no provision in pkgsrc for the build of a package needing the work directory of the build of another package. Would it make sense for dovecot to install those libraries?

[Dovecot] sieve-test again
by Ian P. Christian 23 Feb '09

23 Feb '09

I'm not sure what it is I'm doing wrong here, perhaps my 'test' mail is not in the format expected by sieve-test. The 'test' file is a file taken directly from a dovecot maildir - so is in the normal format of having headers, a new line, then the body. There is nothing exceptional about this email. Notice how the header below is 'innocent', however it appears that the test is ignoring this header. # grep DSPAM-Res test X-DSPAM-Result: Innocent # cat sievetest require ["regex", "fileinto","envelope","reject","vacation","relational","comparator-i;ascii-numeric"]; if header :contains "X-DSPAM-Result" "Innocent" { fileinto "moo"; stop; } # sieve-test -c ./sievetest ./test Performed actions: (none) Implicit keep: * store message in folder: INBOX Info: final result: success I don't think it's this header, but rather *all* headers, as the following check also appears to fail. if header :contains "To" "o" { fileinto "Spam"; stop; } Am I mis-using the tool? Thanks, Ian

[Dovecot] lda catchall
by Stéphane Cottin 23 Feb '09

23 Feb '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm using dovecot lda in a qmail / vpopmail testing environnement. I would like to replace vpopmail lda with dovecot's one , because of quotas , sieve filers, indexing while delivering ... Everything is working great, except the catchall. If I want to bounce, a first line like "# bounce-no-mailbox" in the .qmail file works, without this line, emails to unknown addresses are deferred and stay in the queue, because they are deliverable for qmail, but not for dovecot lda. How can I set a catchall email address for dovecot lda ? thx Stéphane Cottin -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkmixCcACgkQNgQUYqHIqqvttQCfcNBLd9Qo06g5nMcrfZAwVlpv WegAnj7jIA/XFJWmt/2jkg1sxRYKRaI7 =JTTV -----END PGP SIGNATURE-----

http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta1.tar.gz http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta1.tar.gz.sig Largest changes since v1.1 can be found from http://dovecot.org/doc/NEWS-1.2 Changes since alpha5: - Added support for ESORT extension (also SORT .. RETURN (PARTIAL) from CONTEXT=SORT that allows windowing SORT results) - pop3: If client idles for 10 seconds, commit transaction (allowing mbox to become unlocked). - crashfixes to virtual mailboxes - all kinds of bug fixes, error message improvements, etc. - http://dovecot.org/patches/1.2/stats-plugin.c may give some interesting statistics about commands There isn't really much left to do for v1.2.0 except some small fixing to shared mailbox code. And writing documentation for it..

[Dovecot] IMAP ACLs and global ACLs in v1.2
by Timo Sirainen 23 Feb '09

23 Feb '09

I just committed code for IMAP ACL support based on the code from Kolab people. I did quite large changes though. I also changed how global ACLs are handled. Previously local ACLs could override global ACLs, but now that users are able to modify the ACLs I think it should be the other way around. From what I've heard global ACLs are typically added for things like 1) disallowing user from doing something in specific mailboxes such as expunge messages, 2) giving a specific master user access to some mailboxes ONLY, such as voicemail. For 1) case a user really shouldn't be able to grant himself privileges back but still should be able to share the mailbox to others (so the global ACL should have 'a' privilege). For 2) case a user shouldn't be able to remove privileges from the voicemail. So now the user can freely update the local ACLs in whatever way he wants. But in the end if there are any global ACLs, all the local ACLs for those identifiers are ignored. Also local negative identifiers are ignored, so that e.g. global "user=foo lr" can't be disabled by a local "-user=foo lr" ACL. I guess I should update the Wiki ACL page about how exactly the ACLs are applied now that they're well in my memory. :) One thing I'm not really sure about is the "owner" handling. IMAP ACL specifications have no such concept. I think many/most other servers simply add a default ACL for the user name directly. It's a useful concept though, especially with the global ACLs. So currently Dovecot replies: x getacl inbox * ACL "inbox" "owner" lrwstiekxacd x OK Getacl completed. But should it just internally convert "owner" to "username" when replying? But then again if there's a separate rule directly for the "username" it breaks. Do any of the existing ACL-capable IMAP clients want to see the username in the ACL reply or can they handle "owner" just fine? Also what about global ACLs? The current code just lists them twice with local ACLs, which is definitely wrong: x getacl foo * ACL "foo" "xx" w "xx" lr "owner" lrwstiekxacd x OK Getacl completed. Perhaps the global ACLs could have a prefix character? Maybe '#'? Which reminds me, the current dovecot-acl file is mapped to IMAP ACLs like this: dovecot-acl : IMAP ACL - anyone : anyone - authenticated : authenticated - owner : owner - user=name : name - group=name : $name - group-override=name : !$name So all global ACLs would get the # prefix, like #anyone, #name, #!$name. Any thoughts? BTW. Listing shared mailboxes still doesn't work. I guess we'll see tomorrow if I still have energy to get that done.

I am using Thunderbird 2.x as my client, Dovecot on the server (POP3 not IMAP). Currently I have in my conf file: protocols = pop3s pop3 ssl_disable = no ssl_cert_file = /usr/share/ssl/certs/dovecot.pem ssl_key_file = /usr/share/ssl/private/dovecot.pem ssl_parameters_file = /var/run/dovecot/ssl-parameters.dat disable_plaintext_auth = yes login = pop3 In Thunderbird, I have the email server setup to: - Port 110 - TLS Here's my question: If I change protocols = pop3s pop3 to protocols = pop3s I can no longer connect to my mail server via Thunderbird unless I setup Thunderbird to use SSL. Am I doing something wrong? Thanks, John

[Dovecot] Problem with v1.1.10
by Cyrus Rahman 22 Feb '09

22 Feb '09

I've been using 1.1.8 successfully but tried out 1.1.10 this morning. I have a combination of system and virtual users. The system users were unaffected by the change, but the virtual users all lost access to their mail because their home directories, as interpreted by dovecot, moved from user@domain to user@user@domain. The location of the home directory is given to dovecot for virtual users using the static db as uid=vmail gid=vmail home=/var/vmail/%u mail=maildir:~/Inboxdir Were there any changes in this area that might have caused the problem?

[Dovecot] dovecot 1.2 virtual folders question
by Robert Schetterer 22 Feb '09

22 Feb '09

Hi Timo is this possible a possible setup ? for downloading imap folders ( including inbox ) with pop3 controlled by a a dovecot-virtual file in usr/local/virtual/%d/%u/ with content something like that * -Trash -Trash/* -Sent -Sent/* -Drafts -Drafts/* all namespace private { separator = / prefix = "" location=maildir:/usr/local/virtual/%d/%u/:CONTROL=/usr/local/virtual/%d/%u/:INDEX=/usr/local/virtual/%d/%u/ inbox = yes subscriptions = yes list = yes } namespace private { prefix = virtual/ separator = / location = virtual:/usr/local/virtual/%d/%u:LAYOUT=maildir++ inbox = no } it doesnt work yet, but i am nearly sure that i havent understand http://wiki.dovecot.org/Plugins/Virtual perhaps you might bring me on the way background : i want to include a global sieve rule which sorts marked spam mails in a subfolder of inbox called Junk, so that users never can overide it and set perhaps an autoreply by an Sieve rule by incomming mail to inbox to make it possible that pop3 users may fetch sorted Spam mails outta the Junk folder too, i wanna use virtual setup folders Trash , Sent , Drafts are standart folders are standart and should be ignored with that -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] DIGEST-MD5 user/realm mismatch with Postfix
by Darren Pilgrim 22 Feb '09

22 Feb '09

This is a follow-on to the "SQL field format for digest-md5?" thread. After some additional debugging, I've found the problem is a mismatch in what Dovecot expects and Postfix uses for the user and realm. For a username "user(a)example.com" and password "sekret", Dovecot expects: username = "user" realm = "example.com" but Postfix sends the checksum of: username = "user(a)example.com" realm = "" How do I fix this?

[Dovecot] One Dovecot serving 2 domains - possible?
by k bah 22 Feb '09

22 Feb '09

I'm talking about Dovecot 1.0.x, since 1.1.x showed some problems on some of my servers. -- Is it possible to have Dovecot on one machine serving two different domains? How can I set the mailboxes root to one domain to /dir1/ and to the other domain to /dir2/ ? I want all mailboxes from one domain to reside on a different mailbox root. I use Dovecot LDA. Is is possible to set a LDAP config to one domain and another LDAP config to the other (the auth part, I wan't users to reside on different bases on my LDAP tree, so search bases need to be different) thanks in advance = Scrublade Wipers New, Heavy Duty, wiper design to remove bugs and road slime. http://a8-asy.a8ww.net/a8-ads/adftrclick?redirectid=2b9f0c9f1afcc5e7181028e… -- Powered by Outblaze

[Dovecot] auth-worker always opens PAM session
by Miguel Di Ciurcio Filho 21 Feb '09

21 Feb '09

I'm using Dovecot 1.1.7 on CentOS 5.2. I've changed my passdb from passwd to pam, it works fine, but I've found this messages on /var/log/secure: dovecot-auth: PAM adding faulty module: /lib64/security/pam_limits.so dovecot-auth: PAM unable to dlopen(/lib64/security/pam_limits.so) dovecot-auth: PAM [error: /lib64/security/pam_limits.so: failed to map segment from shared object: Cannot allocate memory] Latter I realized that my auth_process_size was 64. Changed it to 128 and problem solved. But I suspect that dovecot should not be opening sessions, because there is no session=yes on my passdb configuration. According to the docs: args = dovecot [session=yes] [setcred=yes] [failure_show_msg=yes] [cache_key=<key>] [<service name>] session=yes makes Dovecot open and immediately close PAM session. Some PAM plugins need this to work, such as pam_mkhomedir. I checked the source code in passdb-pam.c: struct pam_passdb_module { struct passdb_module module; const char *service_name, *pam_cache_key; unsigned int pam_setcred:1; unsigned int pam_session:1; unsigned int failure_show_msg:1; }; And this: /* -session for backwards compatibility */ if (strcmp(t_args[i], "-session") == 0 || strcmp(t_args[i], "session=yes") == 0) module->pam_session = TRUE; It seams to me that the session is going to be opened anyway, since pam_session is always TRUE.

[Dovecot] Maildir with INBOX and other folders at same level
by Seth Rhudy 21 Feb '09

21 Feb '09

Hello- I have set up Dovecot before and feel fairly comfortable with it but am having some issues with a new setup and have not been able to find a solution via Google or the list archives. I use offlineiimap to sync an IMAP account with an email provider. After the sync is complete, my ~/Maildir is set up with a folder called INBOX (with cur,new,tmp inside) and all my other folders set up at same level as INBOX (also with cur,new,tmp inside): ~/Maildir INBOX cur new tmp Otherfolder1 cur new tmp Otherfolder2 cur new tmp etc.. This email provider says that they use '/' as the IMAP folder separator so '.' can be used in folder names. Anyway, I am using Dovecot 1.0.15 on Debian Lenny and can't seem to get Dovecot to recognize this folder structure and display it in my MUA. In my dovecot.conf, I have: mail_location = maildir:~/Maildir When I fire up my MUA it connects fine but does not display anything -- the INBOX is empty and the other folders are not there. I have tried various configurations with the namespace private {} section but without success. What am I missing? Thank you in advance for your assistance.

[Dovecot] Sendmail + Deliver as an LDA probs

[Dovecot] location of temporary files in deliver
by Stuart Henderson 21 Feb '09

21 Feb '09

deliver has the following: -- -- -- /* After buffer grows larger than this, create a temporary file to /tmp where to read the mail. */ #define MAIL_MAX_MEMORY_BUFFER (1024*128) ... static struct istream *create_raw_stream(int fd, time_t *mtime_r) ... input = i_stream_create_seekable(input_list, MAIL_MAX_MEMORY_BUFFER, "/tmp/dovecot.deliver."); -- -- -- On most of my systems, /tmp is relatively small (a few hundred MB, and sometimes on ramdisk), and I like to use /var/tmp for larger temp space. I just had a problem where I exceeded the space available in /tmp while delivering a (multi recipient) message and had to modify the above line to use an alternative location, and recompile.

[Dovecot] How many namespaces for several groups of shared mailboxes ?
by Thomas Hummel 21 Feb '09

21 Feb '09

Hello Timo, let's say you want to implement several distinct groups of shared mailboxes via one (several) public namespace(s) with dovecot-1.1.x/Maildir. For instance, team1, team2 and team3 work on different projects (project1, project2, project3). Obviously, as many public namespaces (#team1, #team2, #team3) would do the trick, but then, any user (including users who don't belong to any above team) would 'see' useless non-selectionable folders #team*. So my idea would be to create only one public namespace (#Public) into which I'd store directories team1, team2, team3, into which I'd put the needed shared mailboxes. Something like /courriel/boites/public/team1/.shared-project1/ /team2/.shared-project2/ /team3/.shared-project3/ with something like namespace public { separator = / prefix = '#Public/' location = maildir:/courriel/boites/public inbox = no hidden = no list = yes subscriptions = yes } I guess if unix right and ACL are set up correctly, other people would only see non-selectionable '#Public'. The only problem is the subscription file : my understanding is that you have only one subscription file per namespace. Maybe unless you specify something like location = maildir:/courriel/boites/public:CONTROL=<some user dependent location> But wouldn't that induce another problem : such a CONTROL directive would put dovecot-uidlist and dovecot-keywords in the same user dependent location. As I want to share the \Seen flag, I have to . put a dovecot-shared file . not specify INDEX (or at least, not to some user dependent location) So I would end up with . uid lists in some user dependant location (as a side effect of having several subscriptions files) . but indexes shared as uid is listed in index : wouldn't that be a problem ? thanks -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] Quota not reporting with getquotaroot

21 Feb '09

I'm running squirrelmail on top of dovecot, and noticed that some of my users display the quota (using the squirrelmail plugin check_quota) and some don't. So I did some digging. For those that do not display the quota, their account also doesn't provide any data with: . getquotaroot inbox * QUOTAROOT "inbox" . OK Getquotaroot completed. When I check the account /Maildir folder it has info in maildirsize 0S 12744423 10 334 1 483685 1 and when I delete the maildirsize file it recreates. any ideas? thx.

[Dovecot] Different protocols with different auth-types
by Morton.Trust 21 Feb '09

21 Feb '09

Hello, I have installed dovecot with MySQL in which the users are stored. Now I want to separate IMAP-Users from POP3-Users. So I added two columns to the user table (imap / pop3) which indicates, whether the user has access to IMAP or not. In order to get dovecot recognizing this separation I put the auth-config into the two protocol-sections and wrote two different dovecot-sql.conf-files. In the dovecot-sql-pop3.conf the query searches for pop3=1 and in the dovecot-sql-imap.conf it searches for imap=1. Done that, I expected POP3-Only-Users getting an error while trying to connect to the IMAP-service. But dovecot first tries to authenticate for IMAP and then uses the POP3-auth as fallback. How can I do this separation? Thanks a lot, Morton -- View this message in context: http://www.nabble.com/Different-protocols-with-different-auth-types-tp22085… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] dict quota
by Osvaldo Alvarez Pozo 20 Feb '09

20 Feb '09

Hi Actually I use quota. But I would like to use dict quota car with dict quota it is possible to view the used quota. But I do not understand the configuration off dict quota. if the quota is stored in mysql wich do I have to specify quota values in plugin section as chown in the dovecot web site? exemples: dict { quotadict = mysql:/etc/dovecot-dict-quota.conf } plugin { # v1.0: 10MB and 1000 messages quota limit quota = dict:storage=10240:messages=1000 proxy::quotadict # v1.1 + SQL: quota = dict:user::proxy::quotadict quota_rule = *:storage=10M:messages=1000 Thanks

[Dovecot] ACL plugin when file in Maildir is not a directory
by Thomas Hummel 20 Feb '09

20 Feb '09

Hello Timo, On a production (by that I mean many users) dovecot-1.1.8/Maidir server where ACL plugin has been enabled, I ran on a log verbosity problem : For some reason (in fact, due to mbox -> Maildir migration script), some people have in their Maildir a .procmail.logfile file. The problem is that dovecot (or the ACL plugin) wants to find a dovecot-acl file in what it would like to be a directory, and then complains : dovecot: IMAP(xxxxxxxx): open(/courriel/boites/xxxxxxxx/.procmail.logfile/dovecot-acl) failed: Not a directory Such a behavior makes the log file grow too much too quickly. Note that my setup regarding log verbosity is at its minimal/default (except for proctitle) : verbose_ssl = no verbose_proctitle = yes auth_verbose = no mail_debug = no auth_debug = no auth_debug_passwords = no One more thing : would I have a log (or in what verbosity setup would I have one) line complaining about no-acl in the system wide acl directory : acl = vfile:/opt/dovecot/dovecot-acls:cache_secs=300 as a matter of fact, /opt/dovecot/dovecot-acls is empty for me (I don't need it for now). thanks -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] v1.2 can't set ACL to empty string
by Sascha Wilde 20 Feb '09

20 Feb '09

Hi *, according to RfC4314 the rights argument to the setacl command might be an empty string ("zero right characters"): The third argument is a string containing an optional plus ("+") or minus ("-") prefix, followed by zero or more rights characters. existing clients (horde in particular) actually use this to remove all rights from an user. Currently dovecot 1.2 does not accept an empty rights string as argument to setacl. Bernhard Herzog will look into this. cheers sascha -- Sascha Wilde OpenPGP key: 4BB86568 http://www.intevation.de/~wilde/ http://www.intevation.de/ Intevation GmbH, Neuer Graben 17, 49074 Osnabrück; AG Osnabrück, HR B 18998 Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner

[Dovecot] Autocreate plugin
by Harry Lachanas 20 Feb '09

20 Feb '09

I've tried to use the autocreate plugin in order to autosubscribe users to public namespaces. namespace public { prefix = Public2/ separator = / location = maildir:/var/Public2:INDEX=~/Maildir/p-idx:CONTROL=~/Maildir/p-crtl hidden=no subscriptions=no inbox = no list=no } with plugin { autocreate = Spam autosubscribe = Spam autosubscribe1 = Public2/News autosubscribe2 = Public2/Shorewall } the plugin works alright with the Spam maildir, but not with the namespaces. Is this possible ??? Thanks Harry.

[Dovecot] Effects of going read-only on dovecot & pop/imap clients
by Mark Zealey 19 Feb '09

19 Feb '09

Hi all, We need to set our filestore to read-only for quite a while, and I want to mitigate the effects for our clients. First issue; dovecot. If we just change the nfs mounts to read-only, dovecot complains: 2009-02-19T14:03:19+00:00 mail2 dovecot: pop3-login: Login: user=<test2(a)markandruth.co.uk>, method=PLAIN, rip=10.15.10.95, lip=10.15.10.102:11002 2009-02-19T14:03:19+00:00 mail2 dovecot: POP3(test2(a)markandruth.co.uk): open() failed with file /var/spool/mail/supplier_2/ma/rk/an/markandruth.co.uk/te/st/2_/test2/Mai ldir/dovecot.index.log: Read-only file system 2009-02-19T14:03:19+00:00 mail2 dovecot: POP3(test2(a)markandruth.co.uk): open(/var/spool/mail/supplier_2/ma/rk/an/markandruth.co.uk/te/st/2_/test 2/Maildir/dovecot-uidlist.lock) failed: Read-only file system 2009-02-19T14:03:19+00:00 mail2 dovecot: POP3(test2(a)markandruth.co.uk): file_dotlock_create(/var/spool/mail/supplier_2/ma/rk/an/markandruth.co.u k/te/st/2_/test2/Maildir/dovecot-uidlist) failed: Read-only file system 2009-02-19T14:03:19+00:00 mail2 dovecot: POP3(test2(a)markandruth.co.uk): Couldn't init INBOX: Internal error occurred.

Is there any way to make dovecot just do as much as it can under the circumstances ie allow read access to mails? Also, has anyone got experience of how clients handle mailboxes being read-only? My guess is that pop clients would probably break and download the same messages over and over?

[Dovecot] limiting authentication failures
by Eric B. Schorvitz, Ph.D. 19 Feb '09

19 Feb '09

In my log files I occasionally get a huge number of Dovecot authentication failures (see clip below). I wanted to know if there's a way to limit the number of times an IP address can attempt to authenticate, if there's a way to have a timeout between attempted authentications, or if there is a way to limit authentication attempts by a specific username within a certain period of time. My current solution is to permanently block the specific IP, an IP range, or an entire country from accessing my server AFTER I notice the huge number of authentication failures. This is too ad-hoc a process and was hoping dovecot has something more proactive built in. Thank you in advance for spending time considering this inquiry, Eric --------------------- pam_unix Begin ------------------------ dovecot: Authentication Failures: rhost=::ffff:200.111.39.219 : 764 Time(s) root: 25 Time(s) mysql: 6 Time(s) smmsp: 6 Time(s) --SNIP-- Unknown Entries: check pass; user unknown: 764 Time(s) ---------------------- pam_unix End ------------------------- --------------------- Connections (secure-log) Begin ------------------------ **Unmatched Entries** dovecot-auth: pam_succeed_if(dovecot:auth): error retrieving information about user info dovecot-auth: pam_succeed_if(dovecot:auth): error retrieving information about user info dovecot-auth: pam_succeed_if(dovecot:auth): error retrieving information about user info dovecot-auth: pam_succeed_if(dovecot:auth): error retrieving information about user info --SNIP--

[Dovecot] sieve filters
by Ian P. Christian 19 Feb '09

19 Feb '09

Hi all, I'm trying to figure out a way of filtering mail from a commercial anti-spam platform. Unfortunately you need to compare part of one header against part of another header. I figured I could solve this using sieve variables and pattern matching, however I'm having little luck and don't know how to debug sieve issues. # example headers: must compare 0.00799 against 1:0000 (the 2nd number in the 2nd header) # X-pstn-levels: (S: 0.00799/98.42547 CV:99.9000 FC:95.5390 LC:95.5390 R:95.9108 P:95.9108 M:97.0282 C:98.6951 ) # X-pstn-settings: 3 (1.0000:1.0000) s cv gt3 gt2 gt1 r p m c if header :matches "X-pstn-levels" "(S: */*" { set "score" "${1}"; if header :matches "X-pstn-settings" " ? (*:*) *" { fileinto "somewhere"; } } The first if appears to match, as if I move the fileinto up there it works - however it doesn't work as it shown here. Can anyone suggest why? Can I achieve what I'm trying to do with sieve? How can I go about debugging scripts? Thanks, Ian

[Dovecot] kerberos trying to obtain credentials for wrong machine
by Nikolay Shopik 19 Feb '09

19 Feb '09

Hi, I'm currently trying to configure Dovecot to use kerberos. My KDC is Windows 2003 and I successful generated keytab file for Dovecot machine. Problem is when I'm trying to use GSSAPI it told me Obtaining credentials for imap@debian5 - and of course this fails because debian5 isn't KDC, it should look for imap/debian5.inblock.local(a)INBLOCK.LOCAL. What I'm missing?

OK.. So I synced the clock.... and got .... dovecot: Time just moved backwards by 1 seconds. I'll sleep now until we're back in present. http://wiki.dovecot.org/TimeMovedBackwards ( The first time I did this the clock moved backwards 2 hours after a timezone change and dovecot suicided ) I think I understand the concept ... However a mail server should probably be synchronized to the local time ..... Suggestions ...??? Harry.

[Dovecot] mbox snarf plugin + idle
by Jonathan Siegle 18 Feb '09

18 Feb '09

I'm having a problem with mbox snarf not looking at /var/spool/mail/ when in idle mode thus never giving me a RECENT line even though there are new messages in /var/spool/mail/ . Here are the imap commands to reproduce the problem: 1 login userid password 2 select inbox 3 idle When I run "select inbox" it does see my messages in /var/spool/mail/ and moves them over fine. When I truss the process, I see it only running stat calls on my "mbox- snarf" file. To get new messages I issue DONE, CLOSE, and SELECT INBOX. I'm not sure why it is reporting alpha5 two lines below. I did an hg pull just the other day and see 1.2.beta1 in the output of hg tags. # /usr/ladmin2/sbin/dovecot -n # 1.2.alpha5: /usr/ladmin2/etc/dovecot.conf Warning: fd limit 2000 is lower than what Dovecot can use under full load (more than 4224).

[Dovecot] Maildir hierarchy sep bug ?
by Thomas Hummel 17 Feb '09

17 Feb '09

Hello Timo, I'm experiencing the following different behaviors with dovecot-1.1.8/Maildir. My Maildir hierarchy separator is the "." (dot) character. My namespaces, when I use them, separator is "/". When I run the server without any namespaces, I can create mailboxes named something like first.name which, of course, are shown to the client as first/ (non selectionnable) first/name For instance in Mutt, if I save a message (the "s" key) from first.name(a)some.domain dovecot happilly creates the .first.name/ Maildir But if I create a public Namespace, then I have to create a private default namespace as well and the server doesn't behave the same way : They're set up like this : namespace private { separator = / prefix = location = maildir:/courriel/boites/%u:CONTROL=/courriel/meta/%u:INDEX=/var/dovecot/indexes/%1u/%u inbox = yes hidden = no list = yes subscriptions = yes } namespace public { separator = / prefix = '#Foo/' location = maildir:/courriel/boites/public/foo inbox = no hidden = yes list = no subscriptions = no } Then users cannot create mailboxes with a dot in it : Character not allowed in mailbox name: '.' which seems normal but can be confusing since, a user used to saving his mail in first.name (in Mutt for instance) wouldn't be able to do so anymore if the server goes from the first to the second setting described above. Granted, a user which does so, probably doesn't do what he thinks he does (he probably thinks he save his message in a folder named "first.name" while instead he actually saves it in a subfolder of "first" named "name"). Still it can be confusing. Is that difference of behavior normal ? Which is the correct behavior ? And is there still no way (except to patch the source) to allow dots in mailbox names in Maildir ?

[Dovecot] dbox redesign
by Timo Sirainen 17 Feb '09

17 Feb '09

This is about how to implement multiple msgs/file dbox format. The current v1.1's one msg/file design would stay pretty much the same and it would be compatible with this new design. dbox directories with multiple msgs/file would be like: ~/dbox/storage/ has the actual mail data for all mailboxes ~/dbox/mailboxes/ has subdirectories containing mailboxes and their indexes Also since dbox supports already the single msg per file, those files would be stored in the mailboxes/ directory. So the idea would be that either you use multiple msgs per file using a global storage, or you use single msg per file without a global storage (or it's also possible to be in a mixed setup with some mails in storage/ and some in mailboxes/, mainly to allow migration between those configurations). The storage/ directory would have a new "map index" which is a regular dovecot index (dovecot.index and dovecot.index.log). So the mailbox index would point to mails using an intermediary "map UID". This way if mails are moved to another file only the map index needs to be updated. GUID would be a globally unique 128 bit ID for messages. So if map indexes get corrupted for any reason it's possible to rebuild it by finding the mails using GUIDs. v1.1 dbox has this "dbox.index" file which I was originally planning on using with multiple msgs/file. It had complex file range locking stuff. Now I'm thinking that it's pretty much useless. The only reason for its existence with the new design is for listing metadata for files converted from Maildir. Map index record would contain: - 32 bit map UID - 8 bit flags (MAIL_DELETED flag = message marked as expunged) - 8 bit unused wasted space - 16 bit refcount - 32 bit file sequence - 32 bit file offset --> total 128 bits/msg Mailbox index: - IMAP UID, flags, keywords, etc. - 32 bit map UID - 128 bit GUID dbox file metadata: - 128 bit GUID - size, vsize, received time, saved time, etc. - initial mailbox name (if all indexes get trashed, we can still figure out at least one mailbox where to put the mail. copies would get lost though.) (- no map UID, no imap UID) How to save a message with multiple msgs/file: 1. Find dbox file where to append to: 1.1. Look up the last message from map index 1.2. Is the file "too old"? (or doesn't exist at all) - Yes -> Create new dbox file 1.3. Is the file "too large"? - Yes -> Look at the previous file (one sequence less) and goto 1.2. 1.4. Try to lock the file. - Fail -> Look at prev file and goto 1.2. Now we have a locked/new dbox file where we can write to. Because 1.4. step only tries to lock the file, there's no waiting on locks. This also means that if e.g. two processes are writing new messages rapidly they may be appending actively to two different files. I don't think that's a problem, better than waiting for locks. 2a) We're using an existing file and we need to find the append offset. Since we found the file by finding the last msg in the file, we also know the last message's offset. I wasn't really planning on saving the message sizes in the index file, so to get the append offset I guess it needs to do an extra read on the last msg's header to find the size and skip over it. Hmm. Or would it be less disk I/O to store the size on the index so it could be found directly? I'm not really sure.. In any case, after we find the append offset, check to see if it's at EOF. If not, that means that either another process just saved a new message there or a process crashed previously and left garbage lying around. Refresh the map index to see if this file+offset exists in it. If not, truncate the file and just continue writing there. If it exists, figure out the new append offset and see again if the file limit would be reached. If the file would become too large, unlock the file and goto step 1. 2b) We're writing to a new file. No need to worry about anything in 2a) 3. Write the message and its metadata to dbox file (including generated 128 bit GUID). 4. Assign map UIDs for the written mails and write APPEND records to map index's transaction log. The record would contain the map UID, file seq, offset, refcount=1. The transaction is saved with a "weak" flag (wonder if there's a better name for this) and its offset is remembered. - If we're creating a new dbox file, it's assigned the file seq and rename()d to the final file name while the map index is locked. 5. Write APPEND record to mailbox index's transaction log with IMAP UID, map UID and GUID (and flags, keywords, etc). 6. Write "commit offset=x" record where x is the offset remembered in step 4. This marks the 4's weak transaction as being fully finished. 7. dbox file is unlocked (if we weren't creating a new file). When reading the index and we see a weak transaction without a commit record, call a resolve() function in dbox code. It finds the dbox file in the weak transaction and tries to lock it. If it can't lock it, it (probably) means that there's still a process that's going to finish the save. If a locking succeeded, run a fixup code that goes through all files that are referenced in weak transactions and makes sure all the refcounts and such are valid. Then it writes commit records for each such transaction. Copying can be done by locking source dbox file, writing a weak "refcount++" transaction and continuing from saving step 5. The only step I can think of where there's a small problem is if data is written to dbox file, then process dies, but no saving is attempted to the same file later. The data is left there as garbage until maybe some day later when a message is expunged from that file and cleanup code notices that there's extra data. I thought about reordering steps so that the records are written to map index first, but that's less efficient when writing multiple messages, because each one would need to be saved separately to the map index (where each save would be lock + fstat (+ read) + write + unlock). This is probably a rare problem which doesn't really matter.. Expunging: The "expunge" and "cleanup to remove deleted space" are separate steps. Preferably the cleanup would be done when the server is "less busy", but I guess it could also be configured to happen either immediately or during logout (or once an hour or so). 1. Write "want to expunge" record to mailbox's transaction log. 2. Write a weak "refcount--" to map index's transaction log. 3. Write "expunged" record to mailbox's transaction log. 4. Write "commit" for the weak refcount--. (The two-stage want-to-expunge(1)/expunged(3) is already done for maildir/mbox also.) I was also thinking maybe this could be just 3 steps without a weak transaction. Especially since without a fsync() between 2 and 3 there's really no guarantee about the order in which 2 and 3 happen. And fsync()s are kind of annoying. But then again if that isn't done and it crashes between 2 and 3 the expunge is tried again later which now decrements the refcount again. If the message's original refcount was 1 it would now be negative. That's not really a problem. More problematic is if the message had been copied to another mailbox and refcount=2, now the refcount would be 0 and the message in the other mailbox would get unexpectedly lost. Not good. Space deletion cleanup: 1. Check from map index header to see there are any refcount=0 mails. Although having this step probably requires some annoying dbox-specific code in index handling code. I guess I'll have to see later if there's a non-horribly-ugly way to do this. 2. Go through all records in the map index. Get a list of files that have refcount=0 records. Also make a copy of file seq+offsets and sort them (so at step 3 we can easily find what mails exist). 3. For each file that has refcount=0 records: 3.1. Try to lock the file. -> Fail: Skip to next file. Either someone's appending to it or cleaning it up already. 3.2. Refresh map index. Add any newly added records to the sorted records list (rare). 3.2. Find the first refcount=0 mail. 3.3. Copy all mails after that with refcount>0 to a new file. 3.4. Lock map index, assign new file seq for the new file, rename() it, for each mail we just copied, using a weak transaction write the seq +offset updates to map index's transaction log. Unlock map index. 3.5. Depending on if first refcount=0 mail was the first mail, either unlink() the file or ftruncate() it. 3.6. Write "commit" record to finish the weak transaction. That's a bit inefficient when cleaning up multiple dbox files, but I'm not sure if there's a much better way unless the map index is locked for the entire time. Since the copying might take a while, a long map index lock is bad since it prevents messages from being saved. Reading mails can be done without locking. But since a file can be truncated unexpectedly, the code must be able to find the new file and offset in that situation and continue reading from there. If the message we were reading was just expunged+cleaned up, the client will have to be just disconnected. Since the cleanup shouldn't normally happen immediately after expunge, this should happen rarely/never. Oh and about all these new temp files that are created. When dbox is opened the dir is stat()ed and if its atime is older than 1 week (currently hardcoded) it readdir()s through the dir to see if there are any old temp* files and then unlinks them. With the new design flags/keywords would never be written to actual dbox files. This helps with backups and also avoids the horribleness of having to increase metadata area. To avoid complete data loss due to index corruption (which really shouldn't be happening nowadays), the indexes are also once in a while backed up to e.g. dovecot.index.backup file. If Dovecot detects missing/broken index, it uses this backup copy to rebuild the index as well as it can. I'm also wondering if it's better for each mailbox to have its separate dovecot.index.cache file or if there should be one cache file for the map index. The upside with one index is that if a mail is copied there's no need to duplicate its cached data. The downside is that I'm worried it would cause more disk I/O, since mailboxes are typically accessed separately, so it might be better that the cache data for one mailbox is stored together rather than all around one bigger cache file.

Hi, I'd like to change the log levels of a few of the errors that Dovecot throws. Our servers throw errors at the console above the 'Error' level, and there are a few that I'd like to change to 'Warn' so that they don't do so. Has anyone out there attempted this and can give me a few pointers? Or is there a doc somewhere about how to do this?

[Dovecot] Replication status
by Asheesh Laroia 16 Feb '09

16 Feb '09

I remember last year we discussed Dovecot replication a bit on this list, e.g. http://www.dovecot.org/list/dovecot/2008-May/030446.html . Has there been any development related to this, and can I help at all? The more I think about the hacks I'm employing to synchronize mail, the more I realize I want this. So hopefully I can put either some money or some time where my mouth is. -- Asheesh. -- Its name is Public Opinion. It is held in reverence. It settles everything.

[Dovecot] Access denied when client is connecting
by Florian Wörter 16 Feb '09

16 Feb '09

Hello! I'm having a problem with dovecot on my gentoo linux box. it would be great if you could help me. i'm planing to use dovecot as imap server. the incoming mails for the different useres are fetched by getmail. for every user a script should be called, which fetches the e-mails of this user from a pop3 server and puts them in ~/mailbox/new. this allready works. now i installed dovecot but everytime a client connects, i find these lines in my dovecot logfile (/var/log/dovecot.log) dovecot: Feb 16 09:08:09 Fatal: chdir(/home/woefl81) failed with uid 1001: Permission denied dovecot: Feb 16 09:08:09 Error: child 16211 (imap) returned error 89 (Fatal failure) the username of the connected user is woefl81, his user id is 1001 and his home directory is /home/woefl81/. i can't figure out why this user has no permission for his own files. well, for testing i now adjusted the directory permissions: in /: drwxr-xr-x 5 root root 152 Feb 10 09:19 home in /home: drwxr-xr-x 6 woefl81 users 296 Feb 11 08:27 woefl81 in /home/woefl81: drwxrwxrwx 5 woefl81 users 120 Feb 9 13:09 mailbox in /home/woefl81/mailbox: drwxrwxrwx 5 woefl81 users 120 Feb 9 13:09 . drwxr-xr-x 6 woefl81 users 296 Feb 11 08:27 .. drwxrwxrwx 2 woefl81 users 48 Feb 9 13:09 cur drwxrwxrwx 2 woefl81 users 120 Feb 9 13:13 new drwxrwxrwx 2 woefl81 users 48 Feb 9 13:13 tmp and finally in /home/woefl81/mailbox/new i find the email which was retrieved by getmail: drwxrwxrwx 2 woefl81 users 120 Feb 9 13:13 . drwxrwxrwx 5 woefl81 users 120 Feb 9 13:09 .. -rwxrwxrwx 1 woefl81 users 4.6K Feb 9 13:13 1234181629.M605602P32438Q0R5b6a645fa35278a9.proxystu as i said before i adjusted the rights for the mailbox subdir for testing to 0777, so everyone really should be able to do everything... my dovecot version is 1.1.11 my config: # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.27-gentoo-r7 i686 Gentoo Base System release 1.12.11.1 log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot_info.log protocols: imap ssl_cert_file: /etc/ssl/dovecot/server.pem ssl_key_file: /etc/ssl/dovecot/server.key disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login login_chroot: no verbose_proctitle: yes mail_location: maildir:~/mailbox auth default: passdb: driver: pam args: * userdb: driver: passwd the user woefl81 is a "normal" system user (from /etc/passwd): woefl81:x:1001:100::/home/woefl81:/bin/bash his main group is users. on the client i installed mozilla tunderbird.. the user connects to the ip of the linux box with his username (woefl81) and the same password as his account pwd on the linux box. it would be great if somebody had an idea what else i should try to get dovecot to work as imap server. thank you very much in advance! best regards, Florian

[Dovecot] unkillable imap process(es) with high CPU-usage
by Arno Wald 15 Feb '09

15 Feb '09

Hello, I am having a problem with my dovecot-daemon. It is forking one or more (I saw up to perhaps 8 of them) imap processes under my user name. These processes are consuming a lot of CPU time and are not killable: > PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND > 8616 arno 20 0 2900 1600 1204 R 98 0.2 1196:38 imap Stopping dovecot does not quit these processes. Killing them (even "kill -9" as root) is not possible. The only solution to get rid of them is to reboot. I have found a mailing list post of one who seemed to have the same problem. He solved it by upgrading to version 1.1. But in my case this did not help. Is this a known problem? What could I check or do? My system: very up to date debian/sid (sidux) kernel 2.6.27-8.slh.1-sidux-686 CPU: Intel(R) Core(TM)2 CPU 4300 @ 1.80GHz Filesystem: ext3fs tried dovecot from sid: 1:1.0.15-2.3 tried dovecot from experimental: 1:1.1.2-3 My dovecot.conf is the original debian configuration with only one line changed into: protocols = imaps # dovecot -n # 1.1.2: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail auth default: passdb: driver: pam userdb: driver: passwd I am using dovecot locally on my system with me as the only user. As client I am using thunderbird alias icedove 2.0.0.17-1. Icedove retrieves the Mails from another imap server and sorts them into Maildir-folders in dovecot. I do not know when the imap-process are going mad. It happens after the system (and the mail-client) is up for a while. Do you need more information? Thanks, Arno

[Dovecot] great disappearing email mystery
by dhottinger＠harrisonburg.k12.va.us 14 Feb '09

14 Feb '09

Have there been any issues with dovecot and using outlook express (imap) as an email client? I have had a couple of users come up with random missing emails. Im trying to figure out if it is user error, or something wacky in my mailserver. I cant find anything telling in maillog files or my messages. Dovecot version is 1.0.3. Its ok to reply to me, I get list messages digest. thanks, ddh -- Dwayne Hottinger Network Administrator Harrisonburg City Public Schools "Everything should be made as simple as possible, but not simpler." -- Albert Einstein "The hottest places in Hell are reserved for those who, in times of moral crisis, preserved their neutrality." -- Dante

We are having the same problem. It's not a problem with imap, only with pop3. We're using deliver as the MDA. We're also using flock() locking for the mbox: is that what everyone else is using as well? Migrating our servers to maildir globally is also not an option for us. In some cases, even convincing customers to use IMAP isn't going to work. One problem which might be making this worse than it needs to be, is the fact that mbox_lock_flock in mbox-lock.c is not using a blocking flock(); instead, it's polling for a non-blocking lock. This technique can cause lock starvation, if another process is dropping the lock and picking it back up again frequently: other processes will only see the lock as being available if they happen to poll for the lock at just the right instant. A better technique to use here, if it's adequately cross-platform, would be to set an alarm() for the max_wait_time, and use a blocking flock(). If the alarm times out and you don't have a lock, it's a timeout. In the meantime, you're guaranteed to eventually get the lock, if it is dropped. That said: I'm not sure whether this will solve our problem in practice. Why doesn't this happen with imap? Why can't we make pop3 do what imap does? Even if it's inefficient, it's better than hanging all incoming mail delivery while deliver eats up our local concurrency limits. Thanks! Alan Ferrency pair Networks, Inc. alan(a)pair.com

[Dovecot] Smooth mailbox to maildir migration
by Luciano Mannucci 14 Feb '09

14 Feb '09

Hi all, I have a postfix+procmail+dovecot installation, now running basicaly on pop3 hence mailbox format, with few thousand users and less than twenty gigabytes mail. I need to move all of them to maildir, to take advantage of IMAP subfolders that do not work with mbox format (so I'm told :). Of course I cannot safely stop the service for more than a bunch of seconds... What I'm about to do: create a second dovecot instance to cope with imap client configured for maildir (and possibly pop3 on another port for those using both), which means a dovecot launched with -c /path/to/alternate.conf and a new /etc/init.d/dovecot2-theRevenge having the proper -i option given to startproc in order to make it ignore the other instance. for each user: convert the mailbox with some sort of mb2mb (which is the better one?) create a .procmailrc with a proper DEFAULT= bearing the magic trailing slash indicating maildir to procmail for each converted user. And I'm done... Have I forgotten something? Is there a better way? Any one else tryed such a thing? Cheers to all, luciano. -- /"\ /Via A.

[Dovecot] Weird Dovecot 1.1.6 + pop3s certificate issues
by Bernhard Schmidt 14 Feb '09

14 Feb '09

Hello everyone, I've been asked by a colleague to have a look at some extremely weird dovecot SSL issue they are seeing on one of the student mailservers. They are running dovecot 1.1.6 (yes, I know, a bit old ...) on SLES 10.2 x86_64 with imap(+starttls), imaps, pop3(+starttls) and pop3s enabled. Every couple of weeks the pop3s and pop3+starttls part bail out out. Clients can't connect, when you try openssl s_client you get this: 15960:error:0407006A:rsa routines:RSA_padding_check_PKCS1_type_1:block type is not 01:rsa_pk1.c:100: 15960:error:04067072:rsa routines:RSA_EAY_PUBLIC_DECRYPT:padding check failed:rsa_eay.c:699: 15960:error:1408D07B:SSL routines:SSL3_GET_KEY_EXCHANGE:bad signature:s3_clnt.c:1414: server logs don't show much except for various SSL_accept() errors, including TLS handshaking: SSL_accept() failed: error:1408F455:SSL routines:SSL3_GET_RECORD:decryption failed or bad record mac TLS handshaking: SSL_accept() syscall failed: Connection reset by peer TLS handshaking: SSL_accept() failed: error:1409441B:SSL routines:SSL3_READ_BYTES:tlsv1 alert decrypt error imaps and imap+starttls work fine during the whole time (and always have), although they are much more used. Restarting dovecot fixes the issue for a couple of weeks. Does anyone have an idea where to start debugging? As far as I understand the whole SSL_accept() thing is a giant blackbox for Dovecot, but how comes it only affects POP3? dovecot -n (paths and addresses altered, not sure how much I can reveal without getting shot): # 1.1.6: /mnt//usr/local/etc/dovecot.conf # OS: Linux 2.6.16.60-0.25-smp x86_64 SUSE Linux Enterprise Server 10 # (x86_64) protocols: imap imaps pop3 pop3s listen(default): [ipv6]:143, ipv4:143 listen(imap): [ipv6]:143, ipv4:143 listen(pop3): [ipv6]:110, ipv4:110 ssl_listen(default): [ipv6]:993, ipv4:993 ssl_listen(imap): [ipv6]:993, ipv4:993 ssl_listen(pop3): [ipv6]:995, ipv4:995 disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable(default): /mnt//usr/local/libexec/dovecot/imap-login login_executable(imap): /mnt//usr/local/libexec/dovecot/imap-login login_executable(pop3): /mnt//usr/local/libexec/dovecot/pop3-login login_process_per_connection: no login_max_connections: 128 max_mail_processes: 2500 mail_uid: campus mail_gid: lmu mail_location: maildir:~/Maildir:INDEX=/home/something/indexes/%-1.1n/%n mmap_disable: yes mail_nfs_index: yes mail_executable(default): /mnt//usr/local/libexec/dovecot/imap mail_executable(imap): /mnt//usr/local/libexec/dovecot/imap mail_executable(pop3): /mnt//usr/local/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /mnt//usr/local/lib/dovecot/imap mail_plugin_dir(imap): /mnt//usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /mnt//usr/local/lib/dovecot/pop3 pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %08Xv%08Xu namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes auth default: worker_max_request_count: 500 passdb: driver: ldap args: /mnt//usr/local/etc/dovecot-ldap.conf userdb: driver: prefetch userdb: driver: ldap args: /mnt//usr/local/etc/dovecot-ldap.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: campus group: lmu plugin: quota: maildir quota_rule: Trash:ignore quota_rule2: *:storage=512M Anyone having an idea? bernhard

Re: [Dovecot] Dovecot-antispam does not work
by Jehan Pagès 14 Feb '09

14 Feb '09

Hi all, just to say that finally the patch of Marcin worked great. Just my configuration is different from yours to get it work: antispam_signature = X-DSPAM-Signature antispam_trash = trash;Trash;Deleted Items antispam_spam = SPAM;Junk antispam_dspam_binary = /usr/bin/dspam antispam_dspam_args = --client;--source=error;--user;%u antispam_mail_tmpdir = /tmp The difference here is in the syntax. You write "--user=somemail" though in the manual, it is written "--user somemail". But also you were proposing 2 lines "antispam_dspam_args" though in all my tests, when I was doing such a thing, the second line seemed to override the first (in the launch logs, only the second line was displayed, so I guess...). Are you sure that it works exactly the way you intend to, Marcin? And that the "--source=error" (your first line) is indeed added as a parameter to the call of dspam? For the patch to the dovecot-antispam, probably it should not be integrated "as is", but I guess that the return code of call_dspam function must probably be checked and fixed if the call can succeed but still give a failure return code. I set Johannes as a main recipient, maybe you will see this email. Bye and thanks all.

[Dovecot] Production server migration from mbox to maildir ( need advice )
by Frank Bonnet 13 Feb '09

13 Feb '09

Hello I'm going to change the raid array of my mailhub in fews days/weeks and I wonder if it would be a good idea to take the opportunity of this migration to also change the storage method from mailbox to maildir. I've never used maildir on my production server only on small satellites. So I really need advice of admins that use maildir format on prod servers. My server has approx 3500 users/mailboxes that is approx 450 Gb of data. The OS is Debian etch amd64 but could change also during the migration Opensuse X86_64, CAOS-NSA, FreeBSD 64 are some options. Any infos/experiences welcome, I'll summarize answers. Thanks a lot.

Re: [Dovecot] Mapping usernames [RESOLVED]

Resolved. For others, this is the simple solution which works for me: /etc/dovecot.conf: auth default { userdb passwd-file { args = /etc/passwd } passdb passwd-file { args = scheme="MD5-CRYPT" /etc/dovecot.passwd } } /etc/dovecot.passwd: bob@vhost.com:$1$yAOjs09l$...::::::userdb_user=vabc_bob (the encrypted password "$1$yAOjs09l$..." comes from /etc/shadow) /etc/passwd: vabc_bob:x:20838:2362:bob:/home/mailusers/vabc_bob:/sbin/nologin "abc" could also be the domain ("vhost"), but this might be too large for really long domain names. So we rather use a short unique prefix for each domain.

[Dovecot] file name missing component in error message

13 Feb '09

Hi, we occasionally see this error message from maildir_mail_set_cache_corrupted(): "Maildir filename has wrong W value: %s/%s" but the path it prints is missing a component, specifically, the new/cur/tmp component. For example: /Volumes/Spool/user/maildir/12345.M123P123.example.com.... should be /Volumes/Spool/user/maildir/cur/12345.M123P123.example.com.... This is using dovecot-1.1.10. Now I just have to figure out why the file is corrupted in the first place.

[Dovecot] quota - implement via dovecot or postfix? which is easier ?
by Linux Advocate 13 Feb '09

13 Feb '09

Guys, i m new to dovecot. I m setting up a new mailserver and planning to run dovecot and postfix of a centos 5.2 box. I have been reading of quota management from various sources and understand that mail box quota can be implemented either thru postfix ( with vda patch ) or thru dovecot. i rather not patch postfix and m therefore leaning towards quota via dovecot. But after reading some posts ,etc, it seems that the information on the dovecot wiki is inaccurate. A.Any comments on this? B. Am i right in concluding that its easier and better in the long run to implement and enforce quotas thru dovecot instead of postfix? C. The right instructions for implementing quota thru dovecot? Regards, marco.

[Dovecot] Released Sieve v0.1.3 and ManageSieve v0.11.3 for Dovecot v1.2.beta1
by Stephan Bosch 13 Feb '09

13 Feb '09

Hello Dovecot users, It has been about two months since the last release of the new Sieve implementation and the ManageSieve service for Dovecot v1.2. Therefore, this release contains quite a few changes. It adds new sieve features like the enotify extension and multiscript support. Also, quite a few (user-reported) bugs were fixed since the last release. Changelog Sieve v0.1.3: * Adapted to changes in Dovecot, making this release dependent on Dovecot >= 1.2.beta1 * Made mail address comparison fully case-insensitive. This is particularly noticeable for the :addresses argument of the vacation command. + Finished enotify extension. Currently, only the mailto notification method is implemented. All still needs to be tested thoroughly. + Implemented multiscript support. It is now possible to execute multiple Sieve scripts sequentially. Administrator-controlled scripts can be executed before and after the user's script. Still needs to be tested thoroughly. + Implemented support for configuring the available Sieve extensions. + Made the subaddress extension (partially) configurable using the sieve_subaddress_sep setting, which allows specifying a (multi-charater) separator other than '+'. + Compiler now warns about invalid header field names used for the header and address tests. + Vacation extension now properly generates a References header for the response message. + Added testing of basic result execution to the test suite. Also added support for testing the outgoing messages produced by the Sieve interpreter. + Included execution of the actual result in the sieve-test command line tool. The undocumented sieve-exec tool that existed for this is now removed as planned. + Added support for the now obsolete 'imapflags' extension for backwards compatibility with CMUSieve. This also implements the mark/unmark commands. - Fixed bugs in the regex extension: 1) if an optional match value did not in fact match, subsequent match values would get unexpected indexes. 2) fixed segfault bug occuring when regex is freed. - Fixed bug in the use of the :from agrument for the vacation command. If this address included a phrase part, the response would not be a valid RFC822 message. - Plugged a theoretical security hole occuring when a directory is opened as a Sieve binary. - Cleaned up and fixed various log messages. - Fixed bug in the outgoing address verification. Addresses ending in ',' were erroneously accepted. Changelog ManageSieve v0.11.3: * Changed the SASL service name from "managesieve" into "sieve" as required in the protocol specification. Don't forget to adjust your configuration if your authentication mechanism depends on this service name. * Adapted to changes in Dovecot, making this release dependent on Dovecot >= v1.2.beta1. * Adapted to changes in the new Sieve implementation, making this release dependent on Dovecot Sieve >= v0.1.3 if used. The old cmusieve plugin is still supported. + Implemented making the SIEVE and NOTIFY capability fully dynamic, meaning that the sieve_extensions setting that was introduced for the new Sieve plugin properly affects the ManageSieve daemon as well. + Added support for the CHECKSCRIPT command. In terms of the supported commands, the ManageSieve daemon now complies with protocol VERSION 1.0 as listed in the CAPABILITY response. - Fixed maximum permissions for uploaded scripts; was 0777. This was shielded however by the default umask (not documented to be configurable), so the actual permissions would never have been 0777. - Fixed a segfault bug in the authentication time-out. Bug report and trace provided by Wolfgang Friebel. - Fixed handling of ~/ in use of mail-data for script location. - Fixed small problems in the login proxy support.

[Dovecot] delivering to folder based on recipient_delimiter?
by dovecot＠corwyn.net 13 Feb '09

13 Feb '09

I'm currently running postfix + dovecot, with virtual users In postfix I have set recipient_delimiter = + so that postfix accepts mail for user(a)example.com, user+foo(a)example.com, and user+spam(a)example.com all deliver to inbox. what I would like is to have email directed to user+foo(a)example.com delivered to the IMAP folder foo (and, in the context of amavisd, have amavis configured for recipient_delimited, and add addr_extension_spam_maps add +spam to each mail identified as spam, and thus the mail would go to the spam folder on delivery. The postfix guys say I should be able to do this. can someone point me to how to implement this with dovecot? (as I don't see how to even start). Thx Rick Rick Steeves http://www.sinister.net "The journey is the destination"

[Dovecot] Can't remove folder (no thunderbird issue)
by Jan Niggemann 12 Feb '09

12 Feb '09

Hi, first of all: yes, I already dug the internet but didn't find a solution - that's why I'm asking you. My provider uses dovecot, although I can't tell you more about the version - sorry. Mail is stored in mbox format. My trouble: I was unable to create subfolders and googled a bit. A proposed solution was to append a slash at the end of the folder name. I used Thunderbird to create a folder and called it "test/" (yes, with a slash). Now, in both, Thunderbird and Mulberry, I'm unable to delete that folder (that contains neither messages nor subfolders). Mulberry doesn't give an error message, and in Thunderbird I can't find an option to remove this folder (no matter if subscribed or not). My provider uses roundcube as a webmail interface. Trying to delete the folder there seems to work OK, but after refreshing the folder-view it re-appears. I have no (ssh|telnet|...) access to the server, so I can't remove the folder using the shell.. Do I have other options than calling support? Thank you already jan

[Dovecot] sendmail smtp auth using client socket
by EQX 12 Feb '09

12 Feb '09

Hi list I searched the net, but could not find something related. Is it possible to export the client socket to sendmail for smtp auth? What would be the sendmail.mc configuration for this? #client { # The client socket is generally safe to export to everyone. Typical use # is to export it to your SMTP server so it can do SMTP AUTH lookups # using it. #path = /var/spool/postfix/private/auth #mode = 0660 #user = postfix #group = postfix #} It can also be the other way round: can Dovecot use Cyrus SASL for user authentication? I need to use sendmail, ip based solutions like pop-before-smtp or poprelay are not an option. Thanks, Mike

[Dovecot] Mapping usernames
by Henry 12 Feb '09

12 Feb '09

Greets, We're using Dovecot 1.0.7 (which comes with CentOS 5.x). I have successfully configured dovecot to change a username from abc(a)123.com to realname1_abc for a machine which only has a single domain (using auth_username_format=realname1_%Ln). However, I'm pulling my hair out trying to get dovecot to handle multiple domains (the machine has existing /etc/passwd /etc/shadow and /etc/mail/virtusertable users). On an older machine, I simply hacked the source code to perform a berkeley DB lookup in /etc/mail/virtusertable.db for the realname[a-z0-9]_xx. This time round, though, I'm trying to do this cleanly. I've been reading the docs/wiki/etc but I now can't see the forest for the trees. This is what I've got so far: In /etc/dovecot.conf: ... auth default { userdb passwd-file { args = /etc/dovecot.passwd } passdb passwd-file { args = /etc/shadow #args = /etc/dovecot.passwd } } /etc/dovecot.passwd contains: realnamea_abc:{PLAIN-MD5}$1$Vjkfhaa....::::::userdb_user=abc@123.com I've been fiddling around blindly with all kinds of settings in userdb {} above, but I always get the error: "passwd-file(abc@123.com,::ffff:127.0.0.1): unknown user", amongst others. In a nutshell, I want to allow a user to login with abc(a)123.com, this name must be mapped to a real system user (eg, using /etc/dovecot.passwd), then authenticated against /etc/shadow or the MD5 password in /etc/dovecot.passwd I would appreciate any kind of pointers or advise here. It would have been nice if vpopmail allowed me to call an external perl script where I could perform the username mapping, but alas, this is not possible.

[Dovecot] v1.2: Can't subscribe to shared user folder
by Sascha Wilde 12 Feb '09

Hi *, I stumbled across a small bug (missing feature?) in the new shared name space stuff: a001 list "" "*" * LIST (\Noselect \HasChildren) "/" "user" * LIST (\Noselect \HasChildren) "/" "user/bob(a)example.com" * LIST (\HasChildren) "/" "INBOX" * LIST (\HasNoChildren) "/" "INBOX/bar" * LIST (\HasNoChildren) "/" "user/bob(a)example.com/brooklebookle" * LIST (\HasNoChildren) "/" "user/bob(a)example.com/foobar" a001 OK List completed. a002 lsub "" "*" a002 OK Lsub completed. a003 subscribe "user/bob(a)example.com/foobar" a003 NO Unknown subscription namespace.

[Dovecot] (Somewhat urgent) Problem with maildir++ quota
by Santiago Romero 12 Feb '09

12 Feb '09

Hi. I have an strange problem with dovecot's maildir quota and postfix. I've tested quota and it works fine but sometimes there are users that having their Maildir/ empty, they trigger the "quota exceeded" message when someone sends email to them. Some config / version info: ### Versions: ii dovecot-common 1:1.0.10-1ubuntu5.1 ii dovecot-imapd 1:1.0.10-1ubuntu5.1 ii dovecot-pop3d 1:1.0.10-1ubuntu5.1 ### From dovecot.conf: (...) # SQL database <doc/wiki/AuthDatabase.SQL.txt> userdb sql { # Path for SQL configuration file args = /etc/dovecot/dovecot-mysql.conf } (...) dict { #quota = mysql:/etc/dovecot-dict-quota.conf } (...) plugin { quota = maildir:storage=51200 } ### dovecot-mysql.conf (splitted to be readable): user_query = SELECT maildir, 5000 AS uid, 5000 AS gid, concat('maildir:storage=', floor(quota/1024)) AS quota FROM mailbox WHERE username = '%u' AND active = '1' ### Database "mailbox" record example: | prueba(a)domain.com | Password | prueba | domain.com/prueba/ | 51200000 | domain.com | 2009-02-02 10:01:24 | 2009-02-02 10:07:46 | 1 | The symptons: users are working nicely, and quota works (If I create a new user and set it a quota of, say, 1MB, I can send him msgs until Maildir reachs 1MB, after that I get "quota exceeded" messages). But sometimes there are users with the Maildir empty that can't receive messages and trigger the "quota exceeded" warning. Users always download messages by POP. Removing "maildirsize" file in their folder fixes the problem. Also fixes it changing the quota to any value (maildirsize is then removed and recreated after a new message arrives for the user). Sometime that I don't know if it's strange is that I don't see "removing" messages in the maildirsize file after user downloads messages. I mean that I can't see "-1" lines in maildirsizes: # cat prueba/maildirsize 51200000S 0 0 615 1 1540 1 11446 1 46085 1 2623 1 21218 1 2815301 1 15110 1 21289 1 18330 1 (and so). Any idea of what's going on? Shouldn't appear "MSGSIZE -1" lines in maildirsize file to "restore" space in Maildir after POP RETRs? Currently I'm fixing the problem with a regular: # find /home/vmail/vhosts -name "maildirsize" -exec rm {} \; But there must exist a better solution (or maybe my config is wrong). Thanks a lot for any help. -- Santiago Romero
