[Dovecot] Upgrading 1.2.17 -> 2.1.x
by Adam G Tilghman 10 Jun '12

10 Jun '12

We're planning to upgrade our site from 1.2.17 to 2.1.x within the next few months, but we must ensure our ability to revert to 1.2.17 if problems arise. I don't expect our maildir storage would present a problem, but am less certain about 2.1.x index/control files remaining readable under 1.2.17. Should I have any reason to worry? -- Adam Tilghman Systems Support / Academic Computing & Media Services agt(a)ucsd.edu 858-822-0711 University of California, San Diego

[Dovecot] Deliver quota-warning via director
by Daniel Parthey 10 Jun '12

10 Jun '12

Hi there, I'm using NFS with Dovecot 2.0.20 and would like to deliver a quota warning to the user using the LMTP director. I have configured quota warnings according to http://wiki2.dovecot.org/Quota/Configuration But it seems that lda delivers the mail directly to the local filesystem and is not using our lmtp director, which prevents NFS mailboxes from getting corrupted. Is there a way to tell lda to use LMTP or the director and ignore the quota while delivering the notification? Regards Daniel

[Dovecot] Dovecot 1.x on AIX -> Dovecot 2.x on Ubuntu
by root＠yuma.acns.colostate.edu 10 Jun '12

10 Jun '12

We are working on migrating Dovecot 1.2.17 running on AIX 5.3 (believe it or not!) to Dovecot 2.0.13 running on Ubuntu. We have hundreds of users mboxes we will be migrating. My question is regarding the index files. Should we remove those after the migration, but before we open it up to users so Dovecot can create new ones? I did a test migration of a single user, and Dovecot detects the architecture change and put out some panic errors, corrupt files and backtrace messages in syslog on Ubuntu. The messages are shown below. If every user is going to generate these types of errors, I'm thinking maybe it makes sense to remove all the .imap directories and let Dovecot create new clean ones. I realize that may slow things down for awhile while Dovecot is rebuilding new files. Thanks for any info.

[Dovecot] director and doveadm server
by Angel L. Mateo 09 Jun '12

09 Jun '12

Hi, I've been reading doc at http://wiki2.dovecot.org/Director to configure my servers. My question is regarding configuration of doveadm server. I have configured both, director and backend servers, as described in that doc, but I don't know how to run doveadm commands in director servers. doveadm is working, because I can run commands, but they are executed in local (director) server. For example: root@myotis40:/etc/dovecot/conf.d# doveadm director status mail server ip vhosts users 155.54.211.169 100 1 but doveadm who seems to be executed just in local: (backend server) root@myotis30:/etc/dovecot/conf.d# doveadm who username # proto (pids) (ips) angel.luis 2 imap (11931 11936) (155.54.67.5) (director server) root@myotis40:/etc/dovecot/conf.d# doveadm who username # proto (pids) (ips) And another question about this... what is the local config option? I haven't found it documented anywhere. -- Angel L.

[Dovecot] director and IPs shown at the backends
by Angel L. Mateo 09 Jun '12

09 Jun '12

Hello, I am configuring a dovecot imap/pop servers with a dovecot director in front of them. Because I am using director proxy, connections in the backends are show as coming from director IPs. Is there any way to configure director (or backends) so the backends know (and report) the original IP instead of the director IP?

[Dovecot] ntlm_auth in Dovecot

Hi, I'm trying getting NTLM auth working against AD in my Dovecot 2.0.15. I'm getting the following error: Jun 08 14:18:11 auth: Info: winbind(?,10.44.3.151): user not authenticated: NT_STATUS_UNSUCCESSFUL "wbinfo -u" reports all the users of the domain and "ntlm_auth --username=%name% --domain="%domain%" gets authenticated successfully. Debugging winbind I can see the following error: [2012/06/08 14:18:11.129611, 10] winbindd/winbindd.c:651(process_request) process_request: unknown request fn number 14 [2012/06/08 14:18:11.129671, 10] winbindd/winbindd.c:738(winbind_client_response_written) winbind_client_response_written[2822:unknown request]: delivered response to client My dovecot.conf is the following: auth_mechanisms = plain ntlm login auth_username_format = %n auth_verbose = yes auth_winbind_helper_path = /usr/bin/ntlm_auth auth_use_winbind = yes auth_debug = yes disable_plaintext_auth = no info_log_path = /var/log/dovecot-info.log log_path = /var/log/dovecot.log mail_location = maildir:/var/mail/domains/%d/%n plugin { autocreate = Trash autocreate2 = Spam autocreate3 = Sent autosubscribe = Trash autosubscribe2 = Spam autosubscribe3 = Sent } protocols = imap ssl = no userdb { driver = static args = uid=100 gid=101 home=/var/mail/domains/%d/%n first_valid_uid=100 } passdb ldap { driver = ldap args = /etc/dovecot/dovecot-ldap.conf } protocol imap { mail_plugins = autocreate } Sounds like there is an issue when Dovecot runs "ntlm_auth". It doesn't appear to be a permission issue (perms are 755). Any help is appreciated. Thank you in advance. -- leonardo.

[Dovecot] [ Re: best practises for mail systems]
by Michescu Andrei 09 Jun '12

Hello, If disk space and bandwidth are affordable (and from your setup it seems that they are affordable as you have everything locally) I would split the mail storage completely and use replication in between n-master servers (n=2 for your case). The replication is not yet fully tested, but Timo is actively working on this feature. The fear of lossing the imap session does not make sense (at least to me) as the client will reconnect automatically in the background. Like this you have no SPOF and no split-brain and you get the flexibility (if needed) to geographically distribute your servers in the the future. Keep each server with its own ip, connect to them via DNS (round robin etc etc). We are currently experimenting with a setup similar to this one, but with geographically distributed servers (trans-continental) (bandwidth limited and high cost).

[Dovecot] Maildir filename has wrong S value
by Wouter de Geus 09 Jun '12

Hello folks, This morning I tried to open an old archive mail folder using Mutt. However, while fetching headers it aborted. Checking the dovecot log gave me this: @400000004fb21996267d37d4 imap(benv): Error: Cached message size smaller than expected (9115 < 9420) @400000004fb21996267e8bac imap(benv): Error: Maildir filename has wrong S value, renamed the file from /home/vpopmail/domains/benv.junerules.com/benv/Maildir/.Old.2009/cur/1260395566.28175.black,S=9115:2,S to /home/vpopmail/domains/benv.junerules.com/benv/Maildir/.Old.2009/cur/1260395566.28175.black,S=9420:2,S @400000004fb21996267e937c imap(benv): Error: Corrupted index cache file /home/vpopmail/domains/benv.junerules.com/benv/Maildir/.Old.2009/dovecot.index.cache: Broken physical size for mail UID 294 @400000004fb21996267eaaec imap(benv): Error: read(/home/vpopmail/domains/benv.junerules.com/benv/Maildir/.Old.2009/cur/1… failed: Input/output error (uid=294) @400000004fb219962680683c imap(benv): Info: Disconnected: Internal error occurred. Refer to server log for more information. [2012-05-15 10:53:32] in=6503 out=192718 I've retried opening this folder several times, but each time Dovecot only fixes 1 file and then aborts. (the folder apparently has a lot more files with incorrect sizes). My question here is: Why does dovecot abort? Isn't the issue fixed after the rename? Also: The files are not corrupted or unreadable, reading them through the commandline works fine. I've looked through my backups and saw that at least half a year ago this mismatch in size was already present. I've been running dovecot for quite a while, so the cause of this size mismatch might very well be a issue in an older version of dovecot / my configuration. Right now I'm running dovecot 2.1.6, but I've been running the v1.2 version for quite a while before that. Is this something that can be improved in dovecot so it doesn't abort after 1 rename? (of course I could script a rename operation, but that seems like a workaround to me) Thanks for reading. Wouter.

[Dovecot] 2.1.7 altmove not working
by Alex Crow 09 Jun '12

09 Jun '12

Hi list, I've just set up a 2.1.7 server, and have migrated a couple of accounts across from a 2.0.15 server, keeping the old configs. I have a strange problem on the new box in that altmove just doesn't work. I have my main storage under /home/email, indexes under /home/indexes and ALT under /home/email_archive. When I run the altmove command, the following broken symlink is created in /home/email/integrafin.co.uk/acrow: lrwxrwxrwx. 1 email email 54 Jun 8 10:46 dbox-alt-root -> /home/email_archive/integrafin.co.uk/a/acrow/mailboxes But nothing is created in the archive other than the empty directory: /home/email_archive/integrafin.co.uk/a/acrow. My mail_location is: mail_location = mdbox:/home/email/%d/%n:INDEX=/home/indexes/%d/%1n/%n:ALT=/home/email_archive/%d/%1n/%n This worked perfectly on the older server. I have attached my doveconf -a output. Any help much appreciated. Regards Alex

[Dovecot] auth-worker problem here.
by Marko Weber 07 Jun '12

07 Jun '12

hello, in howto for gentoo i found this: To tell Postfix about the maps that you've just set up, add the following (substituting mysql for pgsql if you're on PostgreSQL) to the bottom of /etc/postfix/main.cf: virtual_alias_maps = mysql:/etc/postfix/sql_virtual_alias_maps.cf virtual_mailbox_domains = mysql:/etc/postfix/sql_virtual_domain_maps.cf virtual_mailbox_maps = mysql:/etc/postfix/sql_virtual_mailbox_maps.cf Tip: Because this is using the Dovecot's LDA, all results from virtual_mailbox_maps are ignored beyond checking if they exist. I added in the mysql db an alias postmaster(a)domainn.tld that should be forwarded to name(a)domainn.tld. The tip above tells me when using dovecot lda the virtual_alias_maps is ignored by dovecot. now when i send a mail to postmaster(a)domainn.tld the mail is not transported to name(a)domainn.tld. in logfile i see this: dovecot: auth-worker: sql(postmaster(a)zbfmail.de): Unknown user how can i tell dovecot to also use the virtual_alias_maps? thank you marko

[Dovecot] Problem with Dovecot and AD LDAP auth
by Алексей Переклад 07 Jun '12

Hi. Seems it's a bug in dovecot auth. I have FreeBSD 8.1-RELEASE-p1 and I tried 1.2.17 and 2.1.7 versions of Dovecot, and still no luck. The problem: when I set in dovecot-ldap.conf: base = CN=Users,DC=domain,DC=local everything works fine. But if I set: base = DC=domain,DC=local mail client can't authorize. /var/log/dovecot.log says: =============================================== Jun 07 18:07:17 auth: Debug: auth client connected (pid=14611) Jun 07 18:08:11 auth: Debug: client in: AUTH 1 PLAIN service=imap session=G1//aeLB6wAKAABu lip=10.0.0.3 rip=10.0.0.110 lport=143 rport=55787 resp=AGdhdGV3YXkAVU82eUpuUXQ= Jun 07 18:08:11 auth: Debug: ldap(gateway,10.0.0.110,<G1//aeLB6wAKAABu>): bind search: base=DC=domain,DC=local filter=(&(objectClass=person)(sAMAccountName=gateway)) Jun 07 18:08:11 auth: Debug: ldap(gateway,10.0.0.110,<G1//aeLB6wAKAABu>): result: uid missing Jun 07 18:10:18 imap-login: Info: Disconnected: Inactivity during authentication (disconnected while authenticating, waited 127 secs): user=<>, method=PLAIN, rip=10.0.0.110, lip=10.0.0.3, session=<G1//aeLB6wAKAABu> Jun 07 18:10:18 auth: Debug: client in: CANCEL 1 Jun 07 18:10:18 auth: Debug: auth client connected (pid=14706) Jun 07 18:10:26 auth: Debug: client in: AUTH 1 PLAIN service=imap session=n6IBcuLB7AAKAABu lip=10.0.0.3 rip=10.0.0.110 lport=143 rport=55788 resp=AGdhdGV3YXkAVU82eUpuUXQ= Jun 07 18:10:26 auth: Debug: ldap(gateway,10.0.0.110,<n6IBcuLB7AAKAABu>): bind search: base=DC=domain,DC=local filter=(&(objectClass=person)(sAMAccountName=gateway)) Jun 07 18:10:26 auth: Error: ldap(gateway,10.0.0.110,<n6IBcuLB7AAKAABu>): Connection appears to be hanging, reconnecting Jun 07 18:10:26 auth: Debug: ldap(gateway,10.0.0.110,<n6IBcuLB7AAKAABu>): result: uid missing Jun 07 18:10:26 auth: Error: ldap(gateway,10.0.0.110,<G1//aeLB6wAKAABu>): Request lost Jun 07 18:10:26 auth: Error: ldap(gateway,10.0.0.110,<n6IBcuLB7AAKAABu>): ldap_search(base=DC=domain,DC=local filter=(&(objectClass=person)(sAMAccountName=gateway))) failed: Operations error Jun 07 18:10:26 auth: Error: LDAP: Reply with unknown msgid 2 Jun 07 18:10:26 auth: Error: LDAP: Reply with unknown msgid 2 Jun 07 18:10:26 auth: Error: LDAP: Reply with unknown msgid 2 Jun 07 18:10:26 auth: Error: LDAP: Reply with unknown msgid 2 Jun 07 18:10:28 auth: Debug: client out: FAIL 1 user=gateway temp Jun 07 18:10:28 auth: Debug: client out: FAIL 1 user=gateway temp Jun 07 18:13:18 imap-login: Info: Disconnected: Inactivity (auth failed, 1 attempts in 172 secs): user=<gateway>, method=PLAIN, rip=10.0.0.110, lip=10.0.0.3, session=<n6IBcuLB7AAKAABu> ============================================ My dovecot-ldap.conf: =============================== ldap_version = 3 hosts = ad.domain.local base = DC=hrom,DC=local scope = subtree dn = CN=mailserver,CN=Users,DC=domain,DC=local dnpass = here_is_pass auth_bind = yes pass_attrs = uid=user pass_filter = "(&(objectClass=person)(sAMAccountName=%u))" user_attrs = name=mail=maildir:/var/mail/virtual/hrom.local/%n user_filter = "(&(objectClass=person)(sAMAccountName=%u))" =================================================== I need base = DC=domain,DC=local for searching for user's accounts in different OU of my AD.

[Dovecot] Email auto purging applied to all mail folders
by Joe V Aldeguer 07 Jun '12

07 Jun '12

Hello, Is it possible to have this done not only for spam and trash folder but lets say like the user inbox and any user created mail folders too? My ultimate goal is to have a way to automate the email deletion process of emails stored in the user inbox or mail folders when it reaches a specified date. My boss wants to force users to keep emails only a month old anything beyond that will be deleted. Has anyone done this using dovecot and are there any guides available? I am also open to suggestions for commercial solutions but so far searching online for solutions only comes up with email archiving. The dovecot version I have installed is version 2.0.19. Thanks in advance. - Joe

Hi everyone, I recognized a very strange behavior when doing backups of my mdbox mailboxes. After the backup the quota for each mailbox is twice as much as before the backup and I have to recalculate the quota to get the former/correct information. root@mb01:~# doveadm quota get -u test(a)example.com User quota STORAGE 5 10240 User quota MESSAGE 11 - root@mb01:~# doveadm backup -u test(a)example.com mdbox:/home/example.com/test root@mb01:~# doveadm quota get -u test(a)example.com User quota STORAGE 10 10240 User quota MESSAGE 22 - root@mb01:~# doveadm quota get -u test(a)example.com root@mb01:~# doveadm quota get -u test(a)example.com User quota STORAGE 5 10240 User quota MESSAGE 11 - Is this a bug or normal behavior? Regards Patrick

[Dovecot] best practises for mail systems
by Костырев Александр Алексеевич 06 Jun '12

06 Jun '12

hello! Can someone point me to some best practices in building high-available scalable mail system or! share your own success stories. I've read article in LJ "Building a Scalable High-Availability E-Mail System with Active Directory and More" but it seemed to be outdated and there's a single point of failure (Master node). What I want to achieve: high-available, horizontaly scalable, with no single point of failure mail solution. Available hardware: intel mfsys25 modular server with 2 storage controllers, 2 switches, 4 power supply blocks with - 2 blade-servers in mfsys with: 2xIntel Xeon E5620 @ 2.40GHz with 8 cores each - promise vtrak e610s (2 storage controllers, 2 power supply blocks) - 6x 2TB SATA Hitachi HDS72302 We decided to go for KVM virtualization and glusterfs for live migration for vm image but that's not what this is all about :) We installed centos on host systems. for now while we could think of two ways to go: The first way (currently at testing stage): On each host system we created one VM and passed through 3x2TB disks into it. In guests vms on top of this disks we made XFS and fired up glusterfs with distributed replicated volumes for our mailstorage. so it looks like this: vm1 replicate vm2 disk1 ------------> disk4 disk2 ------------> disk5 disk3 ------------> disk6 in each vm we mounted glusterfs and pointed dovecot to that dir for mail creation (as ltmp) and imap4 user access. also we use exim as smtp. So, with glusterfs as mailstorage we can go for LVS to load balancing for exim and dovecot. so wherenever one of host systems (hence one of mail vms) goes down, users don't notice that 'cause LVS points them to working smtp and imap4 servers and they get their mail 'cause of glusterfs. Pros: - high-available - horizontaly scalable - with no single point of failure Cons: - not quite sure if glusterfs is production ready solution 'cause I've experienced split-brains during setting it up - IO performance issue. Though we didn't yet run any io tests, but glusterfs uses fuse to mount on clients. And guys on #gluster told me writing to the glusterfs mount will not be strictly local io. The second way: split up the users mail with: two back-end VMs each other on DIFFERENT host system with - fat mailstorage with raid1+linear mode (mdadm)+XFS - dovecot/exim-back-ends and two VMs for nginx-based proxy servers for imap4 and smtp - nginx can redirect user to right back-end through HTTP-php-based logic. Pros: - we split up not only load for exim/dovecot but users mail IOs too - no split-brains Cons: - If one of the host systems (hence one of back-end VMs with storage) goes down, half of our users is unhappy P.S. Sorry if this place is way wrong to ask for such things.

Tripwire? If the purpose of your query is to automate blocking of brute forcers, this software is not what you want (which detects tampering of critical system files). I suggest trying to find where Postfix failed login reports go, then use your fail2ban or what-have-you to detect and block hosts that repeatedly fail authentication.

[Dovecot] INBOX help needed, dovecot + squirrelmail
by jeep＠rahul.net 05 Jun '12

05 Jun '12

Im trying to figure out how to get dovecot to deliver to my mail_location (example: /opt/imapdata/j/jeff/INBOX/inbox) AND work with squirrelmail. Ive worked on this for hours reading the docs etc with no luck so far. I get dovecot-lda to deliver to: /opt/imapdata/j/jeff/INBOX/inbox but when I use squirrelmail, I see the following in the log: dovecot: imap(jeff): Debug: Effective uid=1006, gid=999, home=/opt/imapdata/j/jeff/INBOX/inbox dovecot: imap(jeff): Error: chdir(/opt/imapdata/j/jeff/INBOX/inbox) failed: Not a directory dovecot: imap(jeff): Debug: Namespace : type=private, prefix=INBOX/, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:/opt/imapdata/j/jeff:INBOX=/opt/imapdata/j/jeff/INBOX:LAYOUT=fs:DIRNAME=mmDIR:INDEX=~/indexes It complains that 'inbox' isnt a directory, but I want it to use: /opt/imapdata/j/jeff/INBOX What parameter do I need to tweak to get this to work? Ive tried the 'folder options' in squirrelmail but that doesnt appear to have any effect here (or at least at this point in my testing). It seems that the only parameter to tweak is 'mail_location' which Im having no luck getting to work correctly. Also namespace may play a part but every combination Ive tried does not result in getting it work thus far. On a sidenote when I send more than 1 email, it doesnt seem to honor 'maildir', it seems its doing 'mbox' instead? I get one flat file. Im lost and confused. my variables: mail_location = maildir:/opt/imapdata/%1n/%n:INBOX=/opt/imapdata/%1n/%n:LAYOUT=fs:DIRNAME=mmDIR:INDEX=~/indexes namespace { type = private separator = / prefix = INBOX/ inbox = yes } Your help is appreciated!

[Dovecot] Customization of "Rejected" message.
by Malloc Kilobyte 04 Jun '12

04 Jun '12

Helo, I'm using Dovecot 2.1.1 with Postfix 2.3.3. I've enabled the quota plugin, so that Dovecot LDA reject e-mails, when user's mailbox is out of space. By default, when mailbox is near quota, and someone tries to send huge message, a reply is automatically send to the sender. It's being send from postmaster named as Mail Delivery Subsystem. And here is my question: Is there some way to customize that auto-reply, so that it is not only being send to the sender but also to recipient gets some notice about failed attempt ? I've also noticed, that this reply has attachment, which is rejected message, but it appears to be empty. Can I configure Dovecot to send back whole rejected message ? Regards malloc4k

[Dovecot] Vacation stopped working

Hi, I'm sure that it WAS working, but I can't guarantee... On a system with dovecot 2.0.16 and dovecot-pigeonhole-2.0_0.2.5. Today a user reported that vacation autoreponse did not work for him. As I have checked the dovecot logs, I see such a message: Jun 04 13:39:51 lmtp(9986, user(a)xxx.com) Info: ZumtCleezE8CJwAAA1GDYg: sieve: msgid=<alpine.LNX.2.00.1206041336520.11397(a)pingwin.sc>: discarding vacation response for implicitly delivered message; no known (envelope) recipient address found in message headers (recipient=<user(a)xxx.com>, and additional `:addresses' are specified) Any idea what actually went wrong?

Something that seems to be missing from this discussion are considerations of privacy and (personal) security. There are fairly serious implications of a sender being able to tell that/when someone has downloaded/opened a message -- including discovery of daily patterns and potentially where the recipient is, or isn't. I think it is our responsibility to understand these issues and explain them to managers/clients in order to bring them along if we refuse (as I would) to provide a capability such as this. [I always set the sendmail "noreceipts" PrivacyOptions so it doesn't respond to these disposition requests.] One approach is to point out to managers/clients that if their system is configured to return read receipts, anyone sending mail to them on that system will be able to get these same types of receipts. When they think about that they may not like the implications and may reconsider their request. Just because it is technically possible to do something (and even if other vendors provide the capability) does not mean that it is the ethically or legally responsible thing to do. - Richard

[Dovecot] Exposing global (default) sieve script through Managesieve
by Matthijs Kooijman 04 Jun '12

04 Jun '12

Hi folks, I'm setting up a dovecot server with managesieve support. I'd like to offer spamfiltering through a Sieve script to my users by default, but still allow them to modify the filtering rules through Managesieve. I found the sieve_global_path configuration option, which seems perfect for what I want. I can configure a default script there, which will work for all users until they set upload their own sieve script using managesieve. However, when configured like this, the user experience isn't quite perfect. When users open the managesieve interface on their client, there is no trace of the default filters, so users might think the spamfiltering is done in some other manner. Now, when they create a filtering rule (e.g., to sort out mail to mailing lists), that rule will overwrite the default spamfiltering rule causing all the spam to spill into the user's mailbox. I'm afraid that most users won't realize they have to manually recreate the spamfiltering rule to fix this. Also, they might not know how to write the rule, even if they do... I've considered a few existing ways to fix this: - Use sieve_before / sieve_after to make sure that the default script is always executed, in addition to any user-supplied scripts. This removes the surprise, but removes the option for users to tweak the spamfiltering rules. - Don't use sieve_global_path, but instead distribute the default script to each user's homedir on user creation. This prevents making changes to the default script for existing users and in my setup, user creation and (mail)homedir creation are nicely separated through an LDAP directory, I'd rather not go this route. - When using the Roundcube webmail application as the IMAP client, I can point Roundcube at the default sieve script. Now, when Roundcube sees there are no scripts through ManageSieve, it shows a (fake) "default" script with the correct contents. As soon as the user changes this script or creates a new script, it is actually uploaded to Dovecot, causing the edited script to be used instead of the global script. This option has the user experience I'm looking for, but having this out-of-band connection from Roundcube to the default script configured with dovecot is ugly (and tricky, since these run on different hosts in my setup). The biggest problem is of course that this only works for Roundcube, not for any other IMAP client my users might use. So, I was wondering: Wouldn't it make sense for the managesieve plugin to do something similar to roundcube: When the user has no sieve script configured, let it fake a single "default" script, showing the contents of the global script? Since the ManageSieve protocol doesn't seem to support any way to flag this situation, it would be fooling the clients a bit, but I'm not sure if that's really a problem. While the user has not script named "default" in his sieve_dir: - include a script called "default" in the LISTSCRIPTS output. - return the contents of the sieve_global_path in the GETSCRIPT "default" command. - remove any sieve symlink after a SETACTIVE "default" command (as if SETACTIVE "" was given). This causes dovecot to fall back to the sieve_global_path script. - the DELETESCRIPT "default" command should fail. This might confuse clients and users, since it is listed in LISTSCRIPTS but cannot be deleted, but I think most users will understand they can't delete the default script. - RENAMESCRIPT "default" "some_name" should copy the sieve_global_path script into the user's sieve_dir. This will effectively copy the script instead of renaming it (since it will still be magically listed in LISTSCRIPTS), so that might be confusing. All other commands work just like they do now (in particular, PUTSCRIPT "default" uploads a script called "default" into the user's sieve_dir, preventing all of the above from applying. As noted above, this change might cause some confusion, but I think that is manageable. On additional thing is that running SETACTIVE "" will not completely disable sieve processing (as would be expected), but will (again) cause the sieve_global_path script to be run. This is already the case currently, though, and should probably be considered a separate problem (whose root cause is the lack of a difference between "no script script configured yet" and "active script disabled", both remove the sieve symlink). Also, this problem might be a feature in some setups, so fixing it might not be so easy... So, any thoughts on this? Any fundamental problems I'm missing? (Not-so) obvious alternatives? Gr. Matthijs

Yes - and it's been discussed here. Some "bright spark" rewrote the kernel epoll code to prevent DoS attacks caused by "excessive forking". That "bright spark" clearly doesn't use imap or webserver software. Redhat backported this change to kernels released after February 2012 and are about to release an emergency kernel release which removes it. A number of $LARGE companies were "not happy" As you've posted, compiling without epoll fixes the problem, but that doesn't help anyone using distro or repo packages.

[Dovecot] interesting stats pattern
by Cor Bosman 02 Jun '12

02 Jun '12

Hey all, im experimenting with dovecot stats service, and graphing the result. My initial results are kind of interesting. Check out this graph showing connected sessions and users: http://grab.by/dReu At first I thought maybe one of our 35 imap servers was having issues sending data, but all individual servers show this patters. Here is a bunch of individual servers: http://grab.by/dReC Anyone have any idea what could cause such a pattern? Maybe dovecot does some cleaning up of idle sessions at specific intervals? Or maybe our loadbalancers do, or the imapdirectors. regards, Cor

[Dovecot] auth trouble
by Glenn English 02 Jun '12

02 Jun '12

Debian Lenny, Dovecot v 1.0.15. I'm getting a lot of what I think is a local socket asking dovecot:auth to verify username/passwords: > May 31 09:00:54 server dovecot-auth: pam_unix(dovecot:auth): authentication failure; logname= uid=0 euid=0 tty=dovecot ruser=admin rhost= Note the empty 'rhost='. That's why I think it's on the server. I see others that look like bots: > May 30 23:08:43 server dovecot-auth: pam_unix(dovecot:auth): authentication failure; logname= uid=0 euid=0 tty=dovecot ruser=admin rhost=200.119.139.22 And I know how to promote the latter to a firewall. But with no rhost, I'm stumped... I've read books, googled, read docs, and asked for help on other mailing lists, and I've learned a lot. And I no longer think it really has much to do with Dovecot, other than the login attempt going through it to get to PAM. But has anyone here seen this before? Is my current theory correct? What did you do to make it go away? (I suspect that upgrading to Debian Squeeze might get rid of it, but I'm afraid that if I don't figure out what's going on, it might just come back.) -- Glenn English hand-wrapped from my Apple Mail

[Dovecot] Inconsistent search results and crash on force-resync
by Joe Beaubien 01 Jun '12

01 Jun '12

Hi, I am seeing inconsistencies in search results (finding 2 emails when only 1 exists, finding the email when it has been moved to another folder, etc). I figured I should run force-resync to fix any issues. I ran the following: doveadm -v force-resync -u <user> <mailbox> and I got some worrysome logs. - I should mention that I have been seeing some crashes of fts-lucene in my logs. I sent a traceback of this on the mailing list 1-2 days ago under the subject "[Dovecot] fts_lucene crashing". - I should also mention that all the problems I am having are only in 1 email account. This email account contains folders of over 100k emails. Do I need to tweak dovecot somehow for this? Up until now all I did was change vsz_limit to 1024 MB for "service imap". Here are the logs: Jun 1 11:15:01 XXXXX dovecot: imap(form): Error: Recent flags state corrupted for mailbox INBOX2 Jun 1 11:15:01 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/INBOX2/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:01 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/INBOX2/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:01 XXXXX dovecot: imap(form): Error: Recent flags state corrupted for mailbox contrat Jun 1 11:15:01 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/contrat/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:01 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/rep_Immigation soi-m&AOo-me/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:01 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/Templates/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:02 XXXXX dovecot: imap(form): Error: Recent flags state corrupted for mailbox rep_eval_positive Jun 1 11:15:02 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/rep_eval_positive/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:02 XXXXX dovecot: imap(form): Error: Recent flags state corrupted for mailbox Sent Jun 1 11:15:02 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/Sent/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:02 XXXXX dovecot: imap(form): Error: Recent flags state corrupted for mailbox form_positif Jun 1 11:15:02 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/form_positif/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:02 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/Archives/contrat/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:02 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/form_positif/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:02 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/form_positif/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:03 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/Archives/form_indetermine/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:03 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/Archives/form_indetermine/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:15 XXXXX dovecot: imap(form): Error: Recent flags state corrupted for mailbox form_indetermine Jun 1 11:15:15 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/form_indetermine/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:25 XXXXX dovecot: indexer-worker: Error: indexer-worker: /home/jd/work/clucene-core-2.3.3.4/src/core/CLucene/index/DocumentsWriter.cpp:210: std::string lucene::index::DocumentsWriter::closeDocStore(): Assertion `numDocsInStore*8 == directory->fileLength( (docStoreSegment + "." + IndexFileNames::FIELDS_INDEX_EXTENSION).c_str() )' failed.

I ran the force-resync 3 times and I still see this message. 3) Any idea why clucene is crashing? Regards, -Joe

[Dovecot] inet_listener imaps { port = 0 } question
by henrixd 01 Jun '12

Hi Why commenting out "inet_listener imaps {}" won't stop dovecot to listen port 993? I think this would be expected behavior. Just curious, finally got it working with port = 0. :) - Henri

Re: [Dovecot] High level of pop3 popping causing server to become unresponsive
by Root Kev 30 May '12

Missed CCing on last reply. See below.. Also, would having Nagios checking the number of messages in a mailbox cause issues with the popping of messages? And/Or would having a user accessing the mailbox from two different applications cause issues? Ie. from Outlook and mobile device? I am under the impression that a lock file is generated which should deal with the issue of contention, deleting mail, etc. Thanks for any information.

Show your doveconf -n output and what error messages you see. Attached to this email (dovecot 2.0 and 2.1 -n outputs) In both cases, we use the same local config file, included from dovecot.conf (I've included both of these too) The error message is: May 30 17:00:31 msslat dovecot: imap(foobar): Error: user foobar: Initialization failed: namespace configuration error: Duplicate namespace prefix: "" May 30 17:00:31 msslat dovecot: imap(foobar): Error: Invalid user settings.

[Dovecot] Strange Dovecot 2.0.20 auth chokes and cores

[Dovecot] i can't make DOTS before mailbox names
by John Goodner 30 May '12

30 May '12

hello i have a real stumper of an issue here and need some help! (config posted below) ok, so i'm building out a new mail system with v1.2.15 of dovecot on debian6 this new system is being designed to seamlessly migrate from an older dovecot mail system (v1.1.3). i have everything almost perfect but i've hit a wall which I need help on. so the existing mailboxes on the old server are as such: cur dovecot.index dovecot.index.cache dovecot.index.log dovecot-uidlist dovecot-uidvalidity dovecot-uidvalidity.4fbffa1a .INBOX.Drafts .INBOX.Sent .INBOX.Trash new subscriptions tmp .Trash NOTICE that it puts the . in before INBOX now on the new mailserver I get this: cur dovecot.index.cache dovecot.index.log dovecot-uidlist dovecot-uidvalidity dovecot-uidvalidity.4fc03e57 Drafts INBOX new Sent subscriptions tmp Trash Notice how it's no longer using DOTS before the names. so what i need to do is make the new mail server DUPLICATE EXACTLY the folder layouts of the old server. i've tried fussing with Namespace and the MailDir and especially the PREFIX option which is seems to ignore a '.' to start a filename. i also fussed with the autocreate hoping i could find something there to adjust. but no good. no matter what i do I can't get it to make or read .Trash .Sent .Drafts! please help me! any advice would be appreciated. i'm also willing to hire someone to finish up the config for me. shouldn't take more than a couple hours. thanks! jg here's my config: root@mailserver1:/# dovecot -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-686 i686 Debian 6.0.5 nfs log_path: /var/log/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_location: maildir:/var/vmail/%d/%n@%d:INBOX=/var/vmail/%d/%n@%d:LAYOUT=fs mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 namespace: type: private separator: . prefix: .INBOX. inbox: yes list: yes subscriptions: yes lda: log_path: /var/log/dovecot-deliver.log auth_socket_path: /var/run/dovecot/auth-master postmaster_address: postmaster(a)m.minla.net mail_plugins: sieve global_script_path: /home/vmail/globalsieverc auth default: passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: static args: uid=1010 gid=1010 home=/home/vmail allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail

It can be added to mail processes also by adding %{session} to mail_log_prefix. + Added ssl_require_crl setting, which specifies if CRL check must be successful when verifying client certificates. + Added mail_shared_explicit_inbox setting to specify if a shared INBOX should be accessible as "shared/$user" or "shared/$user/INBOX". - v2.1.5: Using "~/" as mail_location or elsewhere failed to actually expand it to home directory. - dbox: Fixed potential assert-crash when reading dbox files. - trash plugin: Fixed behavior when quota is already over limit. - mail_log plugin: Logging "copy" event didn't work. - Proxying to backend server with SSL: Verifying server certificate name always failed, because it was compared to an IP address.

[Dovecot] Different SSL requirements for connections on different ports?
by William Gallafent 29 May '12

29 May '12

Hi All, I'm running dovecot 2.0.19. I currently have remote users access mail using IMAP over SSL, with their client certificates being both required and verified. I do this using "ssl = required" and "ssl_verify_client_cert = yes". I would now like to add a webmail front-end (squirrelmail) running on the same server. In order to achieve this I would like to have squirrelmail connecting locally using IMAP, but without the certificate requirement. I'm happy to use the standard IMAP port for this, since that port is firewalled so that only localhost has access. Do I need to run two separate dovecot instances in order to achieve this, or can I somehow configure different SSL requirements for the two ports? Is there a way to have the ssl directives I mention above active only for a certain port (or for certain hosts, i.e. non-local?) I've been looking around in the documentation, but I haven't yet worked out how to do this other than by having two separate dovecot instances running, with the different auth configurations. Is that the best approach, or can I get it working with only once instance? Thanks for any help! -- Bill Gallafent.

[Dovecot] Director and backend on the same server
by James Devine 29 May '12

29 May '12

I have setup director and a backend dovecot service on the same machine using different ports. The backend service is listening on the default 24, 110 and 143 for lmtp, pop3 and imap respectively. Director is listening on 10024, 10110 and 10143 for the same respective services. I can get this setup to work if I have one backend server on a different IP listening on 10024, it seems director tries to use the same port it is listening on when making backend connections. If I point it to the local backend server, it tries to connect to itself which fails. Is there a way to specify the backend ports that director tries to connect to? I see there is a way to specify the port in director_servers but I'm not sure how I would specify the different ports for the different backend services, if this is even possible.

[Dovecot] Dovecot 2.1 mbox + maildir
by Alan Brown 29 May '12

29 May '12

What syntax is needed to make this work? The 2.0 wiki recomendations don't work - I can see the inboxes or the folders but not both at once and there are lots of error messages about prefix clashes if I simply use the existing 2.0.20 conf file on 2.1.6 The layout I have is: Inboxes in mbox format - /var/spool/mail/%u Folders in maildir format - /var/spool/imap/%u/Maildir/ Control and index folders are under separate trees (/var/spool/control & /var/spool/indexes) There's also a mbox area mainly for moving oversized inboxes (/var/spool/imap/%u/mbox/ - prefixed as OLD) Presumably I'm not the only one who's had problems of this type? Thanks in advance for any help Alan

[Dovecot] Bug report - crash on group lookup
by Peter Meier 29 May '12

29 May '12

Hi I was doing some migration from a 1.2 installation to a 2.1. While testing my new installation dovecot crashed at two test-cases constantly with with a "Panic: Trying to allocate 0 bytes" message. Both times it was because I was using a wrong group (or none) in my config. The output I got by dovecot was not that helpful. I only figured it out, that it has something to do with the group by looking at the code, to figure out where the stacktrace I got could come from. Unfortunately, I don't remember one of the examples anymore that correctly (except that it was also a group configuration related issue). The other example, was that I was testing the quota warning scripts: Normal delivery worked fine, but as soon as dovecot should send a quota warning, after the mail got already delivered, I received said panic. For the MTA the mail delivery failed (-> bounce), although the LDA already delivered the mail, but failed in post processing (sending the quota warning). My fix was to add: unix_listener quota-warning { group = mail mode = 0660 } to the quota warning service. The LDA process has an own user per mailbox and the mail group. It looks to me as it would panic by looking up the user of the lda process, but that's pure guess. Attached is a debug output and the configuration that triggered the problem. I see two problems: 1. Don't panic while "looking" up a group 2. Give a meaningful error messages. If you have any further questions, please let me know. ~pete ==> /var/log/dovecot/debug.log <== May 25 12:19:50 lda: Debug: Loading modules from directory: /usr/lib/dovecot May 25 12:19:50 lda: Debug:

[Dovecot] Active Directory : searches in root tree
by nicolasfo 29 May '12

29 May '12

Hello everyone ! I'm trying to make a mail server with dovecot and postfix. Users will authenticate with Active Directory server. I've got an problem with Dovecot. To make the mail server, I'm using IredMail, and I used this tutorial : http://www.iredmail.org/wiki/index.php?title=Integration/Active.Directory.i… here Here's my dovecot-ldap.conf : hosts = dc.domain.lan:389 ldap_version = 3 auth_bind = yes dn = vmail(a)domain.lan dnpass = vmail_passwd base = ou=some_ou,dc=domain,dc=lan scope = subtree deref = never user_filter = (&(userPrincipalName=%u)(objectClass=person)(!(userAccountControl:1.2.840.113556.1.4.803:=2))) pass_filter = (&(userPrincipalName=%u)(objectClass=person)(!(userAccountControl:1.2.840.113556.1.4.803:=2))) user_attrs = =home=/home/mail/%Ld/%Ln/Maildir/,=mail=maildir:/home/mail/%Ld/%Ln/Maildir/ pass_attrs = userPassword=password default_pass_scheme = CRYPT With this configuration file, it works. BUT : To allow Dovecot to find users in my AD database, I must specify an OU in "base". If I only set "dc=domain,dc=lan" the research doesn't work. It seems that Dovecot is not capable to make a research without an OU specified in base. Am I wrong ? The root research works fine with postfix, samba+winbind, and I've an enterprise sized hardware firewall, and it works fine too. I'll be surprised if you tell me that Dovecot can't make a research without OU... That's why I'm posting here.. I've already post about this problem on the Iredmail forum, http://www.iredmail.org/forum/post15184.html#p15184 here , but no solution were found. You're my last hope :) Thanks a lot for replies Nicolas -- View this message in context: http://old.nabble.com/Active-Directory-%3A-searches-in-root-tree-tp33881379… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] GETQUOTAROOT under roundcube
by Adam Szpakowski 29 May '12

29 May '12

Hi, I'm struggling with the proper quota displaying under roundcube webmail. I've tracked the problem to the different responses on GETQUOTAROOT command. Roundcube aquire quota usage using IMAP command: GETQUOTAROOT INBOX Example dump of the roundcube <-> dovecot communication: > GETQUOTAROOT inbox < QUOTAROOT "inbox" "User quota" < QUOTA "User quota" (STORAGE 1198415 10485760) < OK Getquotaroot completed. The same communication using python imaplib: > GETQUOTAROOT inbox < QUOTAROOT "inbox" "User quota" < QUOTA "User quota" (STORAGE 1431260 10485760) < OK Getquotaroot completed. Quota reported to python client is the same as the one reported to Thunderbird and seems to be the proper one. Python test was performed from the webmail same server, the same user. Can someone point me in the right direction? If there is no explanation on IMAP level i'll move the question to roundcube list. software used: - dovecot: 2.0.15, quota limit set in LDAP, usage tracked in SQL - roundcube: 0.7 - python: 2.6.7 Relevant parts of the dovecot config (taken selectively from different files): quota = dict:User quota::proxy::quota quota_rule2 = Trash:storage=+10%% quota_rule3 = spam:storage=+10%% user_attrs = mailQuota=quota_rule=*:bytes=%$ mail_plugins = quota imap_quota dict { quota = mysql:/etc/dovecot/dovecot-dict-used-quota.conf.ext } #dovecot-dict-used-quota.conf.ext map { pattern = priv/quota/storage table = used_quota username_field = username value_field = bytes } map { pattern = priv/quota/messages table = used_quota username_field = username value_field = messages } -- Adam Szpakowski

[Dovecot] per-mailbox message limits
by Alan Brown 29 May '12

29 May '12

This is something Timo hacked up for me a few years ago and I realised should be on the list in case anyone else wants them. The following patches will limit maildir folders to 4000 messages on Dovecot 2.0.* and 2.1.* The Specfile patch is against the Cityfan Redhat EL5 SRPM but is likely to work on most build platforms Changing the message limit requires a recompile. It's brutal and ugly but it prevents users overloading FSes that can't cope with huge numbers of files (EG: GFS2)

[Dovecot] (no subject)
by Phil Petree 29 May '12

29 May '12

Hey All, I'm developing a site on a VPS that comes stock with dovecot 1.2.17 and I'm trying to setup some functionality that is very specific to our business model. My question is this: How do I create (programatically) aliases for a forwarder? I have an address, email(a)domain.com that gets sent to a php script and I want users to be able to send to that script via any number of different names (could ultimately be 1000's). I'm thinking that I append/delete from the etc/aliases file and then run #newaliases So that email(a)domain.com will answer on dummy(a)domain.com or dothis(a)domain.com, once the email comes in, I can check the header, get who it was really sent to, do all my checks, perform the necessary action blah blah blah... and be able to do it all on one piece of code (my fantasy LOL). Am I on the right track here or is this simply not going to work? Thanks, Pete

[Dovecot] AUTH PLAIN fails while AUTH LOGIN succeeds with Exim -> Dovecot SASL auth
by Sandro Tosi 29 May '12

29 May '12

Hello, we're trying to setup a platform with authenticated SMTP with exim and relying on dovecot as auth agent. We've read http://wiki2.dovecot.org/HowTo/EximAndDovecotSASL and so made the changes mentioned there, also setting auth_mechanisms = plain login in conf.d/10-auth.conf . With this setup, we're able to use AUTH LOGIN method on an SMTP session, but using AUTH PLAIN fails. What we receive in the SMTP session is: auth plain `echo -e -n `\0user\0password' | mimencode` 535 Incorrect authentication data (it's actually the output of that command that we put there), and in the dovecot log we see: 2012-05-24 15:04:20 auth: Debug: client in: AUTH 1 PLAIN service=smtp secured rip=127.0.0.1 lip=127.0.0.1 nologin resp=<hidden> 2012-05-24 15:04:20 auth: Info: plain(?,127.0.0.1): invalid input Do you know where we can look to resolve this problem?

[Dovecot] Released Pigeonhole v0.3.1 for Dovecot v2.1.6
by Stephan Bosch 27 May '12

27 May '12

Hello Dovecot users, It's been a few months since the last Pigeonhole release. The main reason is that I've introduced a few big new features. Although the new features themselves probably haven't seen much testing so far, I'm now pretty confident that existing configurations are not broken by these changes. The biggest change is the addition of dict support for Sieve script retrieval. It now possible to fetch Sieve scripts from an SQL database using the Dovecot dict facility. Read the INSTALL file and the referenced additional documentation for more information. Note that this feature currently is not usable with sieve_before/sieve_after and ManageSieve. Additionally, it is now possible to specify multiple sieve_before and sieve_after scripts. This for instance enables administrators to specify both global and user-specific scripts that are to be executed before and after the user's personal script. User-specific scripts configured in sieve_before and sieve_after can not be seen or changed through the ManageSieve protocol. Finally, as promised a while back, I've incorporated the vnd.dovecot.duplicate extension into the main Pigeonhole package. Using this Dovecot-specific extension it is possible to detect duplicate deliveries (such as for example caused by mailing list subscriptions). The detection is based on the message ID and uses the same database file (~/.dovecot.lda-dupes) as the vacation extension. Since the changes introduced in the release are rather large, I strongly advise you to experiment with it a bit before deployment. Changelog v0.3.1: * Added support for retrieving Sieve scripts from dict lookup. This means that Sieve scripts can now be downloaded from a database. Compiled script binaries are still put on disk somewhere if used. The INSTALL documentation is updated with information on this new feature and the (backwards-compatible) changes to the configuration. Note that his feature is currently not supported for sieve_before/sieve_after or script management through ManageSieve. + Incorporated the sieve_duplicate plugin into main Pigeonhole tree as a normal extension (vnd.dovecot.duplicate). This Dovecot-specific extension adds the ability to check for duplicate deliveries based on message ID. Specification can be found in: doc/rfc/spec-bosch-sieve-duplicate.txt + Added support for specifying multiple sieve_before and sieve_after paths. This adds much more flexibility to the multiscript configuration. One application is to have user-specific Sieve scripts outside the user's normal control through ManageSieve. + Added a "session ID" string for managesieve connections, available in %{session} variable (analogous to Dovecot change). - Fixed several small issues, including a few potential segfault bugs, based on static source code analysis. - ManageSieve: changed use of EPROTO error to EIO in ManageSieve string stream implementation because it is apparently not known in BSD. - Gave stamp.h.in (needed for autotools) some content to prevent it from disappearing in patch files. - Fixed bug that caused a SunStudio CC compile failure (reported by Piotr Tarnowski). The release is available as follows: http://www.rename-it.nl/dovecot/2.1/dovecot-2.1-pigeonhole-0.3.1.tar.gz http://www.rename-it.nl/dovecot/2.1/dovecot-2.1-pigeonhole-0.3.1.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] Checkpassword Perl LDAP Implementation
by Jeff Hardy 27 May '12

27 May '12

A few years back I hacked up a perl chkpassldap.pl script to authenticate against ldap, and optionally authorize against groups and/or ldap attributes. This works with both qmail and Dovecot, and it also supports a somewhat generic method to alter the environment suitable to use for Dovecot as a prefetch userdb. Anyway, I have been running the script on a qmail-ldap and Dovecot 1.2 proxying cluster using the stock qmail-ldap attributes without any troubles, and figured I would finally release it in the thought someone might find it useful. http://fritz.potsdam.edu/projects/chkpassldap I tried to document the ins and outs of userdb configuration. If anyone finds anything that could use correction or clarification, please let me know. It has been awhile since I was in the middle of it all. Cheers, -Jeff -- Jeffrey Hardy Network / Systems Administrator hardyjm(a)potsdam.edu

[Dovecot] Dovecot usage values differ from actual disk usage
by Daniel Parthey 26 May '12

26 May '12

Hi, in my dovecot setup the accounting database table shows wrong values which do not correspond with the actual disk space used. The disk usage says 2.6 Gigabytes: mail01:~# du -sh /mail/dovecot/example.org/username 2.6G /mail/dovecot/example.org/username While the doveadm quota get says 7 Gigabytes for the same user: mail01:~# doveadm -f tab quota get -u username(a)example.org Quota name Type Value Limit % User quota STORAGE 7065208 - 0 User quota MESSAGE 282024 - 0 mysql> select * from dovecot.dovecot_usage where username="username(a)example.org"; +----------------------+------------+----------+ | username | storage | messages | +----------------------+------------+----------+ | username(a)example.org | 7234773131 | 282024 | +----------------------+------------+----------+ 1 row in set (0.00 sec) What might be the reason for such huge differences (several gigabytes) between storage value in dovecot_usage table and disk usage value? After a quota recalc everything is correct: mail01:~# doveadm quota recalc -u username(a)example.org mail01:~# doveadm -f tab quota get -u username(a)example.org Quota name Type Value Limit % User quota STORAGE 2630434 - 0 User quota MESSAGE 100714 - 0 mysql> select * from dovecot.dovecot_usage where username="username(a)example.org"; +----------------------+------------+----------+ | username | storage | messages | +----------------------+------------+----------+ | username(a)example.org | 2693565239 | 100714 | +----------------------+------------+----------+ 1 row in set (0.00 sec) How can I keep the accounting data consistent with actual disk usage, without running a recalc cronjob every few hours? There's running a dovecot director and mailbox instance on each of our servers with the mails being stored on NFS and received from postfix via LMTP through the director lmtp port 20024. Configuration of director (dovecot-director.conf) and mailbox (dovecot.conf) is attached. Kind regards Daniel

[Dovecot] Valid config for lda_mailbox_autosubscribe with dovecot 1.2?
by Joan 25 May '12

25 May '12

Hi, Due to some reasons I've to support both dovecot 1.2 and dovecot 2.x, and I just found that the -s parameter I used to autosubscribe to sieve folders doesn't exist anymore in dovecot 2.x The problem arises because (AFAIK) in postfix's master.cf you can only specify one configuration, and I used to have this: dovecot unix - n n - - pipe flags=DRhu user=vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${recipient} -s Is there any way to make the config compatible for both versions, achieving the autosubscribe and not crashing dovecot?

[Dovecot] Berkeley DB with Dovecot
by Jerry 23 May '12

23 May '12

I have a friend who is preparing to set up a small Postfix/Dovecot mail system. There are only approximately 25 users. He wants to use Berkeley DB in a similar fashion to the way Postfix does. I told him I do not believe Dovecot supports that. I could not find any documentation relating to it. 1) Does Dovecot support Berkeley DB? 2) Are their any plans to incorporate that feature into Dovecot? It seems like it could potentially be a very useful feature. I have used it myself when a full blown MySQL configuration seemed like over-kill on other small projects. -- Jerry ♔ Disclaimer: off-list followups get on-list replies or get ignored.

[Dovecot] Dovecot 2 fails after correct login

[Dovecot] Convert from ISO-8859-1 to UTF-8?
by Bjørn T Johansen 20 May '12

20 May '12

The server I am running Dovecot on is still using locale = ISO-8859-1 but I am thinking it is time to convert to UTF-8... Can I just use convmv to convert all the files in the mailboxes to UTF-8 or is there anything else I need to do? Do I need to run iconv to convert the content also or does dovecot/MUA fix this by it self? (i.e. they display the mail as encoded in ISO-8859-1) Regards, BTJ -- ----------------------------------------------------------------------------------------------- Bjørn T Johansen btj(a)havleik.no ----------------------------------------------------------------------------------------------- Someone wrote: "I understand that if you play a Windows CD backwards you hear strange Satanic messages" To which someone replied: "It's even worse than that; play it forwards and it installs Windows" ----------------------------------------------------------------------------------------------- -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

Re: [Dovecot] BEWARE: This list is being harvested for leads

I personally didn't mind a one-time notice from the dev's team that that are now offering paid commercial support. What if I WANTED it? I felt like it was a courtesy email from them to let me know that it's available. If those emails continue unsolicited, then it may start to feel like spam to me, but this did not. In general, I've actually been looking for ways to financially support good open source projects. I have worked with many & find that oftentimes, the ones with hood commercial support tend to be ones that have the manpower resources needed to quickly fix bugs, patch vulnerabilities, maintain a strong development schedule & give decent support through mailing lists & similar means. So when I received the email, immediately I thought: "Hmm. This may come in handy down the road, and would serve two purposes by giving me an easily justifiable means to support the project".

[Dovecot] Best way to change index location on mdbox
by Patrick Westenberg 20 May '12

20 May '12

Hi, right now my index directory is part of the users home directory: mail_home = /var/mail/%d/%n mail_location = mdbox:~/mdbox I want the indexes to be stored in a different location: mail_home = /var/mail/%d/%n mail_location = mdbox:~/mdbox:INDEX=/var/indexes/%d/%n If I just switch this setting and reload the configuration, no e-mails are shown to the user. After restoring the whole maildir I deleted all dovecot.index.*-files from that user and starting dovecot with the new index directory setting, I got the following error after connecting. I expected the index files to be regenerated but I got an error: May 18 23:11:12 imap(test(a)example.com): Panic: file mail-storage.c: line 787 (mailbox_check_mismatching_separators): assertion fail ed: (strncmp(vname, ns->prefix, ns->prefix_len-1) == 0) May 18 23:11:12 imap(test(a)example.com): Error: Raw backtrace: /usr/local/lib/dovecot/libdovecot.so.0(+0x4475a) [0x7f993f60875a] -> /usr/local/lib/dovecot/libdovecot.so.0(+0x447a6) [0x7f993f6087a6] -> /usr/local/lib/dovecot/libdovecot.so.0(i_error+0) [0x7f993f5df5bf] - > /usr/local/lib/dovecot/libdovecot-storage.so.0(mailbox_open_stream+0) [0x7f993f8ccca0] -> /usr/local/lib/dovecot/libdovecot-storage.so. 0(mailbox_open+0xf) [0x7f993f8cccbf] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mdbox_storage_rebuild_in_context+0xb2b) [0x7f993f8 8eeab] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mdbox_sync_begin+0x7ec) [0x7f993f88ce7c] -> /usr/local/lib/dovecot/libdovecot-st orage.so.0(mdbox_sync+0x46) [0x7f993f88cee6] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mdbox_storage_sync_init+0x87) [0x7f993f88c fc7] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mailbox_sync_init+0x31) [0x7f993f8cb851] -> /usr/local/lib/dovecot/libdovecot-stor age.so.0(mailbox_sync+0x27) [0x7f993f8cc387] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(index_storage_get_status+0x28f) [0x7f993f8 ef41f] -> dovecot/imap(imap_status_get+0x7a) [0x41756a] -> dovecot/imap(cmd_status+0x14f) [0x40e85f] -> dovecot/imap(command_exec+0x3d) [ 0x41158d] -> dovecot/imap() [0x41050e] -> dovecot/imap() [0x4105ed] -> dovecot/imap(client_handle_input+0x135) [0x410815] -> dovecot/imap (client_input+0x5f) [0x41113f] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x36) [0x7f993f6148f6] -> /usr/local/lib/dovecot /libdovecot.so.0(io_loop_handler_run+0x9f) [0x7f993f61592f] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_run+0x28) [0x7f993f614898] -> /usr/local/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f993f601023] -> dovecot/imap(main+0x2a4) [0x419364] -> /lib/libc.s o.6(__libc_start_main+0xfd) [0x7f993f280c8d] -> dovecot/imap() [0x408e89] How can I change the index directory without losing mails?

[Dovecot] High level of pop3 popping causing server to become unresponsive
by Root Kev 19 May '12

19 May '12

Hello all, We have put Dovecot 2.1.4 on several of our production servers (CentOS, on Dell R710, with 20GB memory, dual CPU Quad-core). We have a single instance of Dovecot running and currently have several instances of Popa3d. When there are significant amount of popping from 2 mailboxes that dovecot that is popping from (500+ msgs in the mailboxes), the popping of the messages causes the boxes to become unresponsive. We use another application that connects to the Dovecot, downloads 2-10 messages, then processes them, then sends the delete command to Dovecot. When this issue occurs we are unable to become Root, or login again if we close our ssh connection. This only occures when Dovecot is doing the popping. If we only run the older Popa3d, this doesn't occur. We believe it is caused by the way dovecot is authenticating. We are using auth_mechanisms = plain passdb drive = shadow usedb driver = passwd args = blocking=yes If anyone could suggest what could be causing the login issue, we would appreciate any incite to fix it! Thanks, Kevin

[Dovecot] ..::MBOX ISSUE::..
by Alfonso Alejandro Reyes Jimenez 19 May '12

19 May '12

Hi everyone. I have a postfix working with sasl auth and dovecot, everything works fine. I just have 2 issues, the first is that if you add the IMAP mail accounts you can import all the mboxes on the /var/spool/mail/ which we don't want. The second issue is that there's no sent, trash and draft folder, so if we have imap we are not able to store those emails. Basically I would like to know how to fix both but the first one is the most urgent. I thought it was a postfix issue, but it seems not to be. Any ideas? Thanks in advance for your help.

[Dovecot] Authentication with AD and quick mbox question
by Kaya Saman 19 May '12

19 May '12

Hi, I'm attempting to implement Dovecot 2.1.3 built on a FreeBSD 8.2 64 bit system from ports. I had the servicve up and running on a local vbox demo which did a very simple Maildir format sytem which was situated in ~/Maildir. I would now like to expand the system and tie it to a Windows domain. What is the best way to go about doing this? Can Dovecot be directly tied in or do I need to tie the server in to the domain? This is my current dovecot.conf file - which of course I will tweak but as I am currently in the stage of building this is what I have so far: protocols = imap # It's nice to have separate log files for Dovecot. You could do this # by changing syslog configuration also, but this is easier. log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot-info.log # Disable SSL for now. ssl = no disable_plaintext_auth = no # We're using Maildir format #mail_location = maildir:~/Maildir mail_location = mbox:/mail:INBOX=/mail/%u # If you're using POP3, you'll need this: #pop3_uidl_format = %g # Authentication configuration: auth_verbose = yes auth_mechanisms = plain passdb { driver = passwd-file args = /usr/local/etc/dovecot/passwd } userdb { # driver = static # args = uid=root gid=root home=/root/ driver = static args = uid=500 gid=500 home=/ZPOOL_1/%u } Is this correct to use mbox++ format and store under /mail/%u ?? Can anybody give me some advice? Regards, Kaya

[Dovecot] Migration between namespaces breaks outlook on mac's
by Mark Zealey 19 May '12

19 May '12

Hi there, We're running dovecot 1.1 on one set of servers with a courier-imap-like namespace configuration: namespace private { separator = . prefix = INBOX. inbox = yes } We're now migrating customers onto a dovecot-2 platform, switching from Maildir to sdbox (using dsync mirror) & changing the namespace at the same time. New namespace configuration looks like (as taken from http://wiki2.dovecot.org/Namespaces) # This is for courier-imap namespace compatability namespace { type = private separator = / prefix = inbox = yes } namespace { type = private prefix = INBOX. separator = . inbox = no hidden = yes list = no alias_for = } For 99% of clients this works fine eg thunderbird on first login after migration notices the folder structure has changed & automagically redownloads folders & emails. However I have noticed some really strange messages in the logs which seems to be related to customers running outlook on macos. When they login after migration they are generating commands like: dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 1 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 1 1 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 1 1 1 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 1 1 1 1 ... this goes on a long time and we've not yet found a solution other than delete the imap config on their outlook and reconfigure. Does anyone have any idea why this might be happening, or if there is a way we can somehow have old namespaces for old customers, new namespaces for new customers (we are using sql login code so should be possible to do something like this in theory I think?) Thanks, Mark

[Dovecot] TLS X.509 CRLs
by Matthias-Christian Ott 18 May '12

18 May '12

Hi, according to the documentation file referenced by ssl_ca must contain the Client certificate CA and the corresponding CRL. Thus dovecot would have to receive SIGHUP to reload a new CRL. Did I understand this correctly? Regards, Matthias-Christian

[Dovecot] Getting Postfix Admin's DB to work with Postfix's/Dovecot's MySQL DB
by Femi Ajayi 18 May '12

18 May '12

Hi all, I followed the instructions here: http://library.linode.com/email/postfix/dovecot-mysql-centos-5 to configure Postfix to work with MySQL and Dovecot before discovering PostfixAdmin (I was searching for a visual tool for creating users). Since I had created MySQL database already for virtual domains and user mailboxes (following the instructions I linked to earlier) and PostFix admin's db too does the same. Question #1: is there anyway to make all these work with together for the creationg and use of virtual users/mailboxes? or is there another visual tool for creating virtual users/mailboxes? I had also installed Roundcube following the instructions on Roundcube's page: http://trac.roundcube.net/wiki/Howto_Install The questions now is: . #2. Roundcube came with its own database, which also stores user information. Is there a way to ensure that the user information is picked from the database created to work with Postfix (and not Roundcube's)? Thanks.

[Dovecot] Error in dovecot 2.0.13: "Too many levels of symbolic links"
by Tom Pawlowski 17 May '12

17 May '12

Hi all, I've run into an issue we have with dovecot versions 2.0.12 through 2.0.14 on latest CentOS 6.2 when dealing with Maildirs located on NFS partitions. Although I saw Mr. Egbert's thread, his resolution does not work on our end. When dealing with users with over 500 messages in any of their Maildir folders, they occasionally receive an error from the server: Internal error occurred. Refer to server log for more information. The corresponding log entries: dovecot: imap(user1): Error: readdir(/u1/user1/Maildir/.AUTO-DELETED-SPAM/new) failed: Too many levels of symbolic links dovecot: imap(user1): Error: readdir(/u1/user1/Maildir/.logwatch/new) failed: Too many levels of symbolic links dovecot: imap(user2): Error: readdir(/u2/user2/Maildir/cur) failed: Too many levels of symbolic links dovecot: imap(user2): Error: readdir(/u2/user2/Maildir/.Trash/new) failed: Too many levels of symbolic links dovecot: imap(user3): Error: readdir(/u1/user3/Maildir/.Trash/new) failed: Too many levels of symbolic links dovecot: imap(user3): Error: readdir(/u4/user3/Maildir/.AUTO-DELETED-SPAM/new) failed: Too many levels of symbolic links dovecot: imap(user4): Error: readdir(/u1/user4/Maildir/.AUTO-DELETED-SPAM/new) failed: Too many levels of symbolic links dovecot: imap(user4): Error: readdir(/u1/user4/Maildir/new) failed: Too many levels of symbolic links A 'find . -type l' shows there are absolutely no symbolic links to be found in those directories. Running readdir.c that Timo provided always returns errno == 0 on {cur,new} of all the directories reported in the logs. It does not occur consistently in production, but it does tend to occur to a fuzzy set of the same users on different partitions. We can replicate it every time in testing. The file count in these directories are all over the place, from less than a thousand to multiple thousands. However, it's hard to calculate what may have been in new prior to the clients processing/sorting that mail. It may have been more on the higher side than lower. The error tends to favor new over cur, but there are exceptions. The tests we have been trying: Create a new folder using alpine, save anywhere from 1000 to 10000 identical emails to the new folder. Change to that new folder, thus prompting the move from new to cur. The client receives the message and aborts the opening. Anywhere from 400-520 files are successfully moved each time. It takes numerous attempts to finally move all the files over--which I suspect some IMAP clients do, hence the inconsistent errors in production. We then create a brand new folder with the same amount of files and verify that the error is reproduceable--which it is. I'm leaning towards some sort of bug on the NFS client level, as Timo mentioned, but the odd thing is we were running this setup since early April and did not begin seeing these errors until early May--with user load being relatively consistent during that time. I would think the bug would have been evident before then. I'm also curious as to why dovecot is getting an ELOOP error code from it. Any ideas or pointers would be appreciated, sorry for the length. :) -- Tom Pawlowski OIT-CSS System Administrator office: Hill 145 email: tompru(a)jla.rutgers.edu phone: (732) 445-2634

[Dovecot] Migration between namespaces breaks outlook on mac's
by Mark Zealey 17 May '12

17 May '12

Hi there, We're running dovecot 1.1 on one set of servers with a courier-imap-like namespace configuration: namespace private { separator = . prefix = INBOX. inbox = yes } We're now migrating customers onto a dovecot-2 platform, switching from Maildir to sdbox (using dsync mirror) & changing the namespace at the same time. New namespace configuration looks like (as taken from http://wiki2.dovecot.org/Namespaces) # This is for courier-imap namespace compatability namespace { type = private separator = / prefix = inbox = yes } namespace { type = private prefix = INBOX. separator = . inbox = no hidden = yes list = no alias_for = } For 99% of clients this works fine eg thunderbird on first login after migration notices the folder structure has changed & automagically redownloads folders & emails. However I have noticed some really strange messages in the logs which seems to be related to customers running outlook on macos. When they login after migration they are generating commands like: 2012-05-07T00:04:43+01:00 imap-03 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 2012-05-07T00:05:38+01:00 imap-03 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 2012-05-07T00:06:44+01:00 imap-03 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 2012-05-07T00:07:33+01:00 imap-03 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 2012-05-07T00:08:42+01:00 imap-03 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 1 2012-05-07T03:09:00+01:00 imap-03 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 1 1 2012-05-07T03:09:08+01:00 imap-03 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 1 1 1 2012-05-07T03:10:09+01:00 imap-03 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 1 1 1 1 ... this goes on a long time and we've not yet found a solution other than delete the imap config on their outlook and reconfigure. Does anyone have any idea why this might be happening, or if there is a way we can somehow have old namespaces for old customers, new namespaces for new customers (we are using sql login code so should be possible to do something like this in theory I think?) Thanks, Mark

[Dovecot] How to make Dovecot verbous
by Frank Walter 16 May '12

16 May '12

Hello I am struggling with Dovecot 2 (coming from Dovecot 1.0.10) with mysql Authentification for Postfix. I get errors when using it: dovecot: auth: Fatal: Unknown database driver 'mysql' dovecot: master: Error: service(auth): command startup failed, throttling But a first thing would be to log the real errors, if there are any, so I set in /etc/dovecot/conf.d/10-logging.conf auth_verbose, auth_verbose_passwords, auth_debug, auth_debug_passwords, mail_debug, verbose_ssl all to yes and I set: debug_log_path = /var/log/dovecot-debug.log but there is no logfile after restarting dovecot. How can I enable a (verbous) own Logfile in Dovecot? frank

I thought someone could make money coming up with an "unsend" and "untwitter" service that all it does is to queue the outgoing message for 5 minutes, during which the sender can re-consider and remove it from the queue. Sorot of like the kill-switch for live broadcasts. But as the saying goes, you can't make things foolproof, as they keep making better fools. As to the OP trying to determine whether an Email message has been read, an indirect and imperfect technique, used by spammers and marketing critters, is to web bug http://en.wikipedia.org/wiki/Web_bugs It works by placing innocuous individualized tags in HTML formatted Email e.g. "<img src="http://your.domain/?id={hash}>" that downloads a 1x1 dot). You can then correlate web logs with the hashes to see which messages got rendered. A hit does not necessarily mean it got read, and the absense does not mean it was ignored, but it's better than nothing. If you value your privacy, turn off HTML rendering on your Email reader.

[Dovecot] plugin: Don't allow deleting the last instance of a mail
by Timo Sirainen 16 May '12

16 May '12

Before beginning to code it, does anyone have any related ideas that could be useful before starting it? Mainly what I'm intending to do is to write a plugin for mdbox storage that allows users to expunge mails in a specific namespace only if there are other instances for the mail. So basically: * Users can't accidentally delete mails (in shared mailboxes) * Users can still move mails within folders For v2.1 this can be implemented only to a specific storage backend, so at least for now only mdbox will support it. Maildir and sdbox support would also be possible by looking at hard link counts. Race conditions would allow deleting the mails, but that's unlikely to be an issue since the main point is to avoid accidental deletions that shouldn't be attempted in the first place anyway.

[Dovecot] stats + fts squat plugins, indexer-worker error on message indexing
by David Warden 16 May '12

16 May '12

On RHEL 6.2 + dovecot 2.1.5 with the stats and fts (squat) plugins enabled and each user having their own uid on the system I get the following error in the logs when the indexer-worker process indexes some messages: Apr 25 09:56:19 wardentest3 dovecot: imap-login: Login: user=warden, method=PLAIN, rip=137.238.60.164, lip=137.238.2.240, lport=1993, mpid=19464, encryption=TLS Apr 25 09:56:26 wardentest3 dovecot: service=indexer-worker user=warden rip= Indexed 12 messages in INBOX Apr 25 09:56:26 wardentest3 dovecot: service=indexer-worker user=warden rip= Error: open(/proc/self/io) failed: Permission denied Apr 25 09:56:29 wardentest3 dovecot: service=imap user=warden rip=137.238.60.164 Disconnected: Logged out bytes(in/out)=46/780 What I did to generate the above was remove the squat indexes for my Inbox then log in via telnet and search for a string in my Inbox, which forced an index of the messages in my Inbox. Based on http://wiki2.dovecot.org/Services#indexer-worker it seems like this is because the indexer-worker process is created as root but at the time of indexing the indexer-worker drops privs to the mail user. In /proc/<indexer-worker pid>/, io is mode 0400 and owned by root, so it makes sense that the mail user would be unable to read that file. The strange thing is it looks like the stats are still collected (unless I am reading the output of the stats dump incorrectly): [root@wardentest3 mailtest]# doveadm stats dump -s /var/run/dovecot/mailtest/stats command user=warden cmd args session user last_update user_cpu sys_cpu min_faults maj_faults vol_cs invol_cs disk_input disk_output read_count read_bytes write_count write_bytes mail_lookup_path mail_lookup_attr mail_read_count mail_read_bytes mail_cache_hits select inbox 27fb87218302984f084c0000ae899e04 warden 1335362182.950250 0.000000 0.000000 172 0 46 0 0 12288 13 7883 4 381 0 0 0 0 0 search text "warden" 27fb87218302984f084c0000ae899e04 warden 1335362186.588023 0.001000 0.000000 32 0 4 1 0 0 4 108 1 43 0 0 0 0 0 logout 27fb87218302984f084c0000ae899e04 warden 1335362189.161790 0.000000 0.000000 1 0 0 3 0 0 1 108 3 157 0 0 0 0 0 This obviously isn't a show-stopper but if this is causing stats to be incorrect it would be great if this could be fixed. -David Warden My doveconf -n: # 2.1.5: /etc/dovecot/mailtest/dovecot.conf doveconf: Warning: service auth { client_limit=4096 } is lower than required under max. load (12288) doveconf: Warning: service anvil { client_limit=4096 } is lower than required under max. load (12291) # OS: Linux 2.6.32-220.7.1.el6.x86_64 x86_64 Red Hat Enterprise Linux Server release 6.2 (Santiago) nfs auth_cache_negative_ttl = 0 auth_cache_size = 16 M auth_gssapi_hostname = $ALL auth_krb5_keytab = /etc/dovecot/mailtest.combined.keytab auth_master_user_separator = * auth_mechanisms = plain login gssapi auth_username_format = %Ln base_dir = /var/run/dovecot/mailtest/ default_client_limit = 4096 default_process_limit = 4096 deliver_log_format = msgid="%m" subject="%s" from="%f" size=%p result="%$" first_valid_uid = 0 hostname = mailtest.geneseo.edu instance_name = mailtest lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes login_log_format_elements = user=%u method=%m rip=%r lip=%l lport=%a mpid=%e encryption=%c mail_fsync = always mail_location = maildir:/Mail/mailhome/%Ln/mailtest/Maildir:CONTROL=/Mail/mailhome/%Ln/mailtest/.dovecot-control:INDEX=/Mail/mailhome/%Ln/mailtest/.dovecot-index mail_log_prefix = "service=%s user=%u rip=%r " mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = zlib quota mail_log notify fts fts_squat stats maildir_very_dirty_syncs = yes managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave mbox_write_locks = fcntl mmap_disable = yes namespace default { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = no special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = . type = private } passdb { args = /etc/dovecot/passwd.masterusers driver = passwd-file master = yes } passdb { args = cache_key=%u dovecot driver = pam } plugin { fts = squat mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename flag_change append mail_log_fields = uid box msgid size from subject flags mail_log_group_events = yes quota = maildir:User quota quota_exceeded_message = Quota exceeded (mailbox for user is full).

[Dovecot] [Plugin dev] First-time-only cache lock failure
by John G 15 May '12

15 May '12

Hi This is a question related to plugin developement on Dovecot 2.1.4. I'm currently implementing a dovecot plugin that retrieves mails from a corporate server through an internal protocol. The plugin is very similar to the pop3c storage (lib-storage/index/pop3c). The plugin has to map original server UIDs to IMAP UIDs, using MAIL_CACHE_POP3_UIDL cache field the same way pop3c does. So, I've got a function similar to pop3c_sync_messages(), performing several mail_index_append() and mail_cache_add() calls. The problem is that on the first sync, when the index and cache files don't exist yet, there's a failure writing data in cache. The call to mail_index_sync_commit()\mail_cache_transaction_commit() fails because of mail_cache_transaction_lock(). The index and cache files are properly created, but the cache doesn't contain the MAIL_CACHE_POP3_UIDL values. It works properly on the second sync, the MAIL_CACHE_POP3_UIDL field being properly saved. Would you have some ideas on what could be wrong here? Thanks, John

[Dovecot] default mail quota when using per user quota
by Andreas Helmcke 14 May '12

14 May '12

Hello, using dovecot 2.1 and per user mail quota via ldap is there a way to have a default quota which gets used, if the "quota" field in ldap is not set? I tried with: plugin { quota = maildir:User quota quota_rule = *:storage=3G } userdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } and in dovecot-ldap.conf: user_attrs = dcMailQuota=quota_rule=*:storage=%$ but with this configuration the mail quota /allways/ gets loaded from ldap resulting in users without dcMailQuota attribute having no quota at all. Greetings Andreas

[Dovecot] doveadm not working
by Christian Rößner 14 May '12

14 May '12

Hi, I know I must have done some misconfiguration, but I do not know where to start searching for. All began when looking at my weekly cron message, where doveadm purge -A is run. That fails. So I tried doveadm quota -A as well, which several weeks ago was working perfectly. Example: doveadm quota get -A doveadm(root): Error: User listing returned failure doveadm: Error: Failed to iterate through some users Username Quota name Type Value Limit % All I see in the logs is: May 13 13:03:20 mx0 dovecot: auth: Error: auth worker: Aborted request: Lookup timed out May 13 13:03:21 mx0 dovecot: auth-worker(26753): Error: LDAP: ldap_start_tls_s() failed: Connect error May 13 13:03:21 mx0 dovecot: auth-worker(26753): Error: LDAP: ldap_start_tls_s() failed: Can't contact LDAP server Dovecot itself works. Only doveadm does not. My LDAP is using SASL/EXTERNAL. Certs are in standard folders under /etc/ssl/{certs,private} (see below). I guess that "some" user (but which?) tries to read the certs but is disallowed. Can somebody help me please to fix my permissions on that (private used) mail server? Is my "vmail" user required?

[Dovecot] Log files
by Chris Lasater 14 May '12

14 May '12

Hi, I just started using Dovecot and was trying to create separate logs instead of using syslog. Is there a way to get the file permission to be something other then root? I have tried the below configuration and it does not seem to change anything. The log process does change to a new user, but it still creates and writes as root. Whenever I test a new setting I delete all the current logs so they will have to be recreated to make sure it does not just keep the previous permissions. I also dont see much documentation on the service log. according to dovecot -a there are a good number of options, but I dont see any information about them. Here are my logging settings below and I am running 2.1.6 and tried on 2.1.5. ### Logging info_log_path = /home/user/dovecot/logs/dovecot_info.log log_path = /home/user/dovecot/logs/dovecot.log debug_log_path = /home/user/dovecot/logs/debug.log service log { user = user unix_listener log-errors { group = user2 mode = 0620 user = user } } Thanks, Chris

Hello everybody, I have a problem and no idea.

And last week, I copy some mail data from old machine to new one through SCP and CP command. It worked well. Yesterday, I copy the mail data from old machine to new one through RSYNC. I guess maybe the errors have a relationship with rsync, because the new machine open SELinux and the rsync data error. Although the files were copyed to /cur directory , it seemed to appear the same mail file. Now,I receive some BLANK mails by pop3 of OutLook2007 . There are not any Header and any Body( Totally BLANK). Outlook show they are 760B size. I am confusing for this problem. Please help me. Thank you.

[Dovecot] userdb namespace settings bug
by Alexander 'Leo' Bergolth 14 May '12

14 May '12

Hi! Since upgrading to 2.1.6, setting namespaces via environment variables using a imap-postlogin-script *sometimes* doesn't work. Sometimes, the prefix of a namespace isn't set correctly, but is set to an empty string, which leads to the following error: namespace configuration error: Duplicate namespace prefix: "" However, the environment is set correctly, the error seems to occur when parsing the environment. See the attached log: The postlogin-script sets the environment variables attached as dovecot-postlogin-environment.txt. (dumped from postlogin script via env) However, the variable "NAMESPACE/S-GSD/PREFIX=Shared/GSD/" gets parsed as: plugin/namespace/s-gsd/prefix=Shared/GSD/ See the error message: Unknown userdb setting: plugin/namespace/s-gsd/prefix=Shared/GSD/ After restarting dovecot, the same configuration sometimes works correctly. I'd greatly appreciate your help! Unfortunately I have done the upgrade on a production system, so the issue is quite serious for me.. Will downgrading to 2.0 work? (Index-files, etc?)

[Dovecot] dovecot wants to access my music directory
by Ian Pilcher 14 May '12

14 May '12

I am getting an SELinux error every time dovecot starts, because it is trying to access my music directory (/srv/music). I've read the doveadm-mount man page, and tried: doveadm mount add /srv/music ignore but it didn't make any difference. Now, I certainly didn't tell dovecot to access this directory, so how can I tell it *not* to do so. This is dovecot-2.1.6-2.fc17.x86_64 on Fedora 17 Beta, BTW. Thanks! -- ======================================================================== Ian Pilcher arequipeno(a)gmail.com "If you're going to shift my paradigm ... at least buy me dinner first." ========================================================================

[Dovecot] dovecot-2.1.6: why are loglines longer and longer
by Reindl Harald 13 May '12

13 May '12

do we really need "session=<ugAua+i/ewBUcit1>" additional to proxy log-lines? until this change it was possible on a 24" screen with "tail -f /var/log/maillog" to watch without linebreaks, now each proxy line breaks PLEASE reconsider such changes!

[Dovecot] index IO patterns
by Cor Bosman 12 May '12

12 May '12

Hey all, we're in the process of checking out alternatives to our index storage. We're currently storing indexes on a NetApp Metrocluster which works fine, but is very expensive. We're planning a few different setups and doing some actual performance tests on them. Does anyone know some of the IO patterns of the indexes? For instance: - mostly random reads or linear reads/writes? - average size of reads and writes? - how many read/writes on average for a specific mailbox size? Anyone do any measurements of this kind? Alternatively, does anyone have any experience with other redundant storage options? Im thinking things like MooseFS, DRBD, etc? regards, Cor

[Dovecot] /var/run/dovecot folder gets deleted on server reboot? ubuntu 10.10
by jacques 11 May '12

11 May '12

Hi After rebooting my server connections to the mail system set up there failed - on closer inspection no dovecot process was running or got started. When running as root /usr/share/sbin/dovecot -c /etc/dovecot/dovecot.conf got error on console /var/run/dovecot/auth-master could not be opened and found no /var/run/dovecot folder!. Is there better script to place in /etc/init.c/ to start dovecot (which will not fail silently?) Any idea what would remove the folder on ubuntu 10.10, running dovecot 2.1.5 and postfix 2.1.7? Any suggestions? Jacques

Hello, Another question!! Was just trying to sort out mail delivery to subdomains. I set up my system so that I have a mail address of tim(a)subdomain.example.com. I've sorted out Postfix to correctly identify this and pass on to Dovecot for delivery but Dovecot doesn't seem to deliver where I want it to. Ideally I would like to have a structure so that mail is delivered to /var/mail/example.com/subdomain/user My users are stored in MySQL and they are being pulled out correctly, but dovecot is delivering to /var/mail/subdomain.example.com/tim Looking at my logs it seems that the mail location is being picked up not being acted on...

[Dovecot] Request for help with dovecot.conf file: configured to work with MySQL and Postfix.
by Femi Ajayi 10 May '12

10 May '12

Greetings, I have CentOS 6.2 running on our server with a VPS provider (Linode.com) I need to configure Postfix, dovecot, MySQL to work for virtual domains (multiple domains on our server). The only instructions for setting up Email with Postfix, Dovecot and MySQL my host provides is for the configuration on CentOS 5 which is here: http://library.linode.com/email/postfix/dovecot-mysql-centos-5 , I followed it for the installation/configuration of Email with Postfix, Dovecot and MySQL on our CentOS 6.2 Everything seemed to work fine until I got to the editing of the dovecot.conf file. The guide on the Linode Library provides instructions for Dovecot 1.x, while the newer versions of CentOS (CentOS 6) , apparently use Dovecot 2.x. The config file format has changed, so the one in the guide is no longer applicable, and as a result, I got a errors.. I would therefore appreciate it greatly if someone with a copy of the Dovecot 2.x dovecot.conf file configured to work with MySQL and Postfix (for handling mails for multiple domains) could share it with me. You could get a better understanding of the problem if you take some time to look at the instructions I followed so far: http://library.linode.com/email/postfix/dovecot-mysql-centos-5 ..and also the forums where I had previously sought help: http://forum.linode.com/viewtopic.php?p=50603#50603 http://www.linuxquestions.org/questions/showthread.php?p=4672839#post4672839 Thanks in anticipation of your help.

[Dovecot] Thunderbird log-in --->Authentication failed - password in uppercase in log files
by jacques 10 May '12

10 May '12

Hi I use dovecot 2.1.5 with postfix, amavis, spamassasin, mysql, virtual domains only. Dovecot being used for SASL authentication, and delivery. When I connect via telnet to port 25 or with smtp and try to do auth plain with mmencode connection string authentication works fine. I can send and recieve messages, and relay works as well. Trying to set up thunderbird to connect to this server I get problems - seems as if the password is resolved proper from the database (use postfixadmin), but then compares an upper case version of my password in the MD5-CRYPT() call to the password string obtained from the database. I do see the base64 encoded connection string in dovecot log though.

[Dovecot] Enforcing Dovecot Quotas
by tcsmith1978 10 May '12

10 May '12

Hello, I have been looking at enforcing quotas for users of my mail system (postfix and Dovecot v1.2). Have tried to follow a few tuts on the web but its not having the desired effect. Essentially I can still send and receive mail on an account that I believe has had its quota exceeded. In my main.cf, I have: userdb sql { args = /etc/dovecot/mysql/dovecot-mysql.conf } passdb sql { args = /etc/dovecot/mysql/dovecot-mysql.conf } and... protocol lda { mail_plugins = quota } protocol imap { mail_plugins = quota imap_quota } plugin { quota_exceeded_message = You have exceeded the maximum quota for your mailbox } the dovecot sql (mysql) file has the following query for pulling out user ids and quotas etc: user_query = SELECT maildir, mymailuser as uid, mymailgroup as gid,concat('maildir:storage=',quota) as quota FROM virtual_mailbox WHERE username = '%u' I have set one of my users to have a quota of 1 (so one byte I believe) so it should be over the limit pretty much immediately. Looking at the logs I can see that the system is picking up on the quota limit but doesn't seem to enforce it. Apr 27 10:29:02 deliver(test(a)testdomain.com): Info: auth input: quota=maildir:storage=1 Apr 27 10:29:02 deliver(test(a)testdomain.com): Info: Quota root: name=storage=1 backend=maildir args= Any ideas?

[Dovecot] dovecot and systemd
by Michal Hlavinka 09 May '12

09 May '12

Hi all, dovecot supports systemd socket activation. Together with standard unit activation (like old sysv init script), there are two ways how to configure dovecot(only interface:port, not whole configuration). This can result in situation where those configurations does not say the same. Question is what should happen then? For example, lets have dovecot configured to listen for imap(s) and lets have systemd dovecot socket configured to listen for all protocols - pop3(s) and imap(s). When dovecot is configured to start on boot, systemd will start it and dovecot will listen on imap(s) ports. But when dovecot.socket is enabled, it'll listen on pop3(s) too and when new pop3 connection comes, it'll pass it to dovecot and dovecot will serve it. The question is: Should this happen? What exactly should happen when dovecot.conf does not match dovecot.socket configuration? Michal

Re: [Dovecot] Dovecot for POP3S proxying

Dovecot is installed but actually I just use auth module (for postfix authentication). In your dovecot.conf example, I don't see the "proxy" command ?

If you already have dovecot running in proxy mode it's easy to add pop3s. If not, see http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy See http://wiki2.dovecot.org/Services search the page for pop3s.

[Dovecot] IMAP NOTIFY extension

your work on NOTIFY was brought to my attention, and I see it hasn't been changed in two months, a week after you announced it. a few users and some mail admins have been wanting something like this for k9 mail, which I help develop. what is the current status? is it worth installing and starting work in getting k9 to support it yet? I'd offer help on your end, but I just know java and perl. c code usually confuses me (i keep meaning to learn, but...). thanks! -ashley -- Sent from my Android phone with K-9 Mail.

[Dovecot] courier to dovecot
by Grafibit Rendszergazda 08 May '12

08 May '12

Dear All, I know there were many threads on this topic. I was searching the archive and the net also, but did not find a solution on my problem. I hope you can help me. I am migrating from an old server using courier to a new server with dovecot and i can not manage to have the same uids after the migration. After copying the message files from the old server to the new, and executing the script from the wiki page the messages are still re-downloaded by the mail clients. After telnet and logging in to the old server port 110, I got the following on the command *uidl*: 1 UID377-1278276092 2 UID387-1278276092 3 UID394-1278276092 4 UID498-1278276092 5 UID499-1278276092 6 UID564-1278276092 On the new server i set up the *pop3_uidl_format = UID%u-%v* because it seems for me that the old server is using the same uidl format. Either if i execute the /./courier-dovecot-migrate.pl --to-dovecot --recursive --convert /command or i don't the uidls on the new server won't be the same. Both the %u and %v numbers are differ. Please give me any hints how to continue the investigation to have a successful migration.

Yes, that's possible. The IMAP/POP3 servers behind Dovecot director wouldn't even need to be Dovecots at all. Although you really want to use v2.1 director since it has a lot of fixes compared to v2.0.

[Dovecot] Proxying for some users and having the rest local?
by Dr Josef Karthauser 07 May '12

07 May '12

I'm migrating a load of mailboxes from cyrus to a new dovecot server. What I'd like to do is to switch the DNS to dovecot, and set things up so that all old imap mailboxes are accessed through the dovecot proxy. That way I can migrate them one at a time independent of DNS issues. I've got a load of users specified in mysql, and that configuration works well for local mailboxes. How do I configure things so that I can switch proxy access on and off? What's I've got so far is: password_query = SELECT user, domain, password, "masteruser" as master, "masterpass" as pass, proxy, "remoteimap.server" as host FROM mailboxes \ WHERE user = '%n' AND isMailbox AND active AND domain = '%d' I imagined that I could switch the proxy per user by setting proxy='n' or proxy=null for any users that want to be local, and proxy='y' for any users that I want to forward on to the original server. It doesn't appear to work that way though. Irrespective of the proxy value dovecot appears to try and proxy all users. What am I doing wrong? I can't work it out from the docs, and the source will take quite a bit of studying to get to the bottom of it all. Thanks :), Joe

Im sorry to ask another basic question, but Ive tried to find this answer for several hours now and it eludes me. Im getting the following when dovecot tries to deliver an email: May 6 19:29:21 mydomain dovecot: lda: Debug: auth input: jeff home=/opt/imapdata/j/jeff/INBOX uid=1001 gid=999 May 6 19:29:21 mydomain dovecot: lda(jeff): Fatal: setgid(999(vmail) from userdb lookup) failed with euid=999(vmail), gid=500(jeff), egid=500(jeff): Operation not permitted (This binary should probably be called with process group set to 999(vmail) instead of 500(jeff)) I cannot seem to find where its trying to call dovecot-lda with uid(jeff) at? AFAIK Ive set everything up to use/deliver as 'vmail'. 'jeff' is the only person on this box with a unix account which is uid 500, but how do I make it use vmail instead? Thanks for the help!

It can be added to mail processes also by adding %{session} to mail_log_prefix. + Added ssl_require_crl setting, which specifies if CRL check must be successful when verifying client certificates. + Added mail_shared_explicit_inbox setting to specify if a shared INBOX should be accessible as "shared/$user" or "shared/$user/INBOX". - v2.1.5: Using "~/" as mail_location or elsewhere failed to actually expand it to home directory. - dbox: Fixed potential assert-crash when reading dbox files. - trash plugin: Fixed behavior when quota is already over limit. - mail_log plugin: Logging "copy" event didn't work. - Proxying to backend server with SSL: Verifying server certificate name always failed, because it was compared to an IP address.

I'm not sure what's triggered it - I THINK it has something to do with a force-resync, but not sure. I'm no longer viewing my full list of shared mailboxes. I used to have a number of users shown - they had all had their ACL's set individually and were shown in the list. "doveadm acl debug" shows they SHOULD be shown - at least I think so, as the output for the mailboxes that DO appear is identical for those that don't. Where should I look for breakage? -- Daniel

Given the above, and SIS - if the backup is performed in the same spool, i.e. original is /var/mail/domain/user, backup is /var/mail/domain/user-new - will this result in any problems with SIS? If after the pack and rename operation, the old mail tree is simply deleted - will that leave SIS files unreferenced if the user later deletes the messages from their active store? -- Daniel

[Dovecot] Authentication process holding open filehandles
by George Barnett 07 May '12

07 May '12

Hi, We're using dovecot to provide pop3 for a number of mailboxes. The setup is pretty simple: Each user / domain has a mailstore in /data/mailstore/<domain>/<user>/Maildir (backed by NFS). Passwords are in simple passwd-file format in the top level domain directory eg: # cat /data/mailstore/foo.com/.passwd user:{plain}password The passdb setup looks like this. passdb { args = username_format=%n /data/mailstore/%d/.passwd driver = passwd-file } The problem we're having is that when we want to remove a domain from the system and we go to rm -rf /data/mailstore/<domain>/ we are unable to because the auth process is still holding onto the file handles for the password file. Can somebody suggest an alternative pattern that I could use for storing password files? Ideally, we'd avoid one large file to prevent locking issues and would also keep the passwd-file setup since it's simple. It would be possible to have the password files in a separate dir, but over time I'm guessing that would lead to nfs turds? Easy to clean up I suppose, but maybe there's a simpler solution I'm missing? George

Hello, Thanks for dovecot, as it's still the best mail server. I'd like to use per users sieve_after scripts. Can I put in my dovecot config file, something like that: sieve_after = %h/Mails/Sieve/After/ It would be very useful for me, as I'd like to add vacation script to be executed from this place. Kind regards, André.

[Dovecot] Shared INBOX change in v2.1.6?
by Timo Sirainen 04 May '12

04 May '12

Previously Dovecot has shown shared INBOX like: * LIST (\HasChildren) "/" "shared/tss2" * LIST (\HasNoChildren) "/" "shared/tss2/INBOX" * LIST (\HasNoChildren) "/" "shared/tss2/foo" The last change in hg makes it return simply (same as with Cyrus): * LIST (\HasChildren) "/" "shared/tss2" * LIST (\HasNoChildren) "/" "shared/tss2/foo" This behavior could be made optional, but does anyone actually want it to work the old way (and why)? I'd rather not add an option that isn't useful to anyone. I think older Dovecot versions have allowed opening both shared/tss2 and shared/tss2/INBOX, but at least in v2.1 that code was broken. With the last change it's still possible to open both of them, the shared/tss2/INBOX just isn't visible in LIST output.

[Dovecot] dovecot sasl with postfix: SASL LOGIN authentication failed: Connection lost to authentication server
by David Jonas 04 May '12

04 May '12

When using dovecot (2.1.5) sasl with postfix (2.8.4) behind nginx smtp proxy I am seeing a ton of errors of the form: postfix/smtpd[7731]: warning: unknown[192.168.0.6]: SASL LOGIN authentication failed: Connection lost to authentication server Nothing is printed by dovecot in the logs regarding the error. It seems that dovecot just hung up on postfix. (side note: no, can't use xclient in nginx/postfix. But perhaps soon.) After much digging I thought I solved it with: login_trusted_networks = 172.20.20.0/24 mail_max_userip_connections = 0 This seems safe enough because dovecot is only providing sasl to postfix, no connections to the outside world. But the error is still happening. # doveadm penalty IP penalty last_penalty last_update 172.20.20.61 1 2012-04-30 19:15:56 19:15:56 strace on the anvil process shows a lot of GETs and INCs: 18:54:06 read(14, "PENALTY-GET\t172.20.20.61\n", 397) = 25 <0.000016> 18:54:06 write(14, "1 1335837245\n", 13) = 13 <0.000029> A two minute survey showed penalty distribution: 0: 60% 1: 15% 2: 18% 3: 8% Finally I just disabled penalties with the info from http://www.dovecot.org/list/dovecot/2011-December/062631.html and that seemed to do it. Is there a better way? This took me a long time to run down so I tried to make this message detailed enough that others with similar problems will stumble upon it.

Hi all, I use "doveadm mailbox mutf7 -7 $folder" to convert imap foldernames to UTF-8. If $foldername is not mUTF-7 encoded, doveadm returns "doveadm(root): Error: Mailbox name not valid mUTF-7: $folder" This errormessage is printed on stderr but the returncode of doveadm is zero. I tested with dovecot-2.0.* and dovecot-2.1.* # all right: $ doveadm mailbox mutf7 -7 'gr&APw-n'; echo $? grün 0 # also all right, no mUTF-7 encoded folder: $ doveadm mailbox mutf7 -7 'gruen'; echo $? gruen 0 # wrong $ doveadm mailbox mutf7 -7 'grün'; echo $? doveadm(root): Error: Mailbox name not valid mUTF-7: grün 0 Would be nice if doveadm exit with an errorcode != 0 in that case.

Hello. I have been on leave for several weeks and have managed to lose all emails received since December due to a server crash. I asked about log synch error back in March and have (repeatedly) deleted all .imap files but the errors continue. # 2.1.1: /usr/etc/dovecot/dovecot.conf # OS: Linux 2.6.33.5-desktop-2mnb i686 Mandriva Linux 2010.2 mail_access_groups = mail mail_location = mbox:~/Mail:INBOX=/var/spool/mail/%u managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap pop3 lmtp sieve sieve ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol lmtp { mail_plugins = sieve } protocol lda { mail_plugins = sieve } Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=929952 for /home/john/Mail/INBOX/.imap/Archive/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=548744 for /home/john/Mail/INBOX/.imap/Davies/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=541084 for /home/john/Mail/INBOX/.imap/FieldNET/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=539768 for /home/john/Mail/INBOX/.imap/Invoices Out/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=492896 for /home/john/Mail/INBOX/.imap/Lawrence and Hanson/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=530300 for /home/john/Mail/INBOX/.imap/Logger Call/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=524384 for /home/john/Mail/INBOX/.imap/Logger Reset/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=500144 for /home/john/Mail/INBOX/.imap/River Murray/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=532680 for /home/john/Mail/INBOX/.imap/SMS Emails/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=515436 for /home/john/Mail/INBOX/.imap/Soil Moisture Alert/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=578508 for /home/john/Mail/INBOX/.imap/Water Management Alarm/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=648164 for /home/john/Mail/INBOX/.imap/Water Usage/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=492876 for /home/john/Mail/INBOX/.imap/Weather Summaries/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=495744 for /home/john/Mail/INBOX/.imap/Zerna/dovecot.index: Extension header update points outside header size Apr 30 09:00:38 server dovecot: lda(john): Error: Log synchronization error at seq=2,offset=578596 for /home/john/Mail/INBOX/.imap/Water Management Alarm/dovecot.index: Extension header update points outside header size Apr 30 09:00:38 server dovecot: lda(john): Error: Log synchronization error at seq=2,offset=578684 for /home/john/Mail/INBOX/.imap/Water Management Alarm/dovecot.index: Extension header update points outside header size Apr 30 09:00:38 server dovecot: lda(john): Error: Log synchronization error at seq=2,offset=578880 for /home/john/Mail/INBOX/.imap/Water Management Alarm/dovecot.index: Extension header update points outside header size At about the same time, I asked about fsck warnings.

[Dovecot] mdbox corruption
by Daniel L. Miller 02 May '12

02 May '12

I have isolated the corruption in a mailbox to 4 mdbox files. Two of these (smaller) files cause the force-resync to report a breakage and save the file as m.XX.broken. The other two (larger) files cause a crash. Is there a way I can fix these files and recover the mails? -- Daniel

[Dovecot] dovecot, ldap and multiple auth_bind_userdn
by Cédric Jeanneret 01 May '12

01 May '12

Hello List! I'm having some troubles for a client of mine: he has two ldap branches which may contain valid users for imap login... For now, dovecot is configured so that it uses the auth_bind: ======== uris = ldap://localhost:389/ auth_bind = yes auth_bind_userdn = uid=%u,ou=user,dc=org ldap_version = 3 base = dc=artemis user_attrs = user_global_uid = 8 user_global_gid = 8 pass_attrs = uid=user ## other options user_filter = (uid=%u) pass_filter = (uid=%u) default_pass_scheme = CRYPT ======== Unfortunately, I cannot manage to tell him "hey guy, uses those two branches": uid=%u,ou=user,dc=org and uid=%u,ou=external,dc=org Is there a special way to do that ? Is it even possible ? I cannot modify the ldap tree, so this option is out, unfortunately :(. My dovecot version: dovecot --version 1.2.15 Thanks in advance for your answers. Cheers, C.

[Dovecot] question dovecot Inheritance global acl vs userfolder acl
by Robert Schetterer 01 May '12

01 May '12

Hi Timo my tests resulted in inheritance is given if a userfolder has set some acl to its new created subfolder , which is nice if some userfolder has its acl from global acl there is no inheritance to its new created subfolders, that subfolders will always created with full owner rights i am not really sure if its a good idea to have inheritance from global acl and if its hackabel what is your idea to this ? -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

Hello, i'm using kmail2 and for Folder Settings the SETANNOATION command is needed. Is there any way to add this command to Dovecot? I already found a dovecot-metadata-plugin but there is no Package available for Debian. Thanks Dieter

[Dovecot] restoring mails and directories
by oni-neko＠gmx.net 01 May '12

01 May '12

Good day! is there an easy way to restore e.g. deleted mails and/or mail directories? let me specify: I'm running dovecot 1.2.9 on a current ubuntu lts. It is set to Maildir and I backup the folder with the users maildata nightly via rsync. now, when someone deletes a mail that they still need, and I copy it back from the backup, it will not be visible to mail clients. When I change the mailfile by a letter or so, it shows. that's easy enough, if not exactly awesome ;-) But, if said person deletes a whole folder of mails, this way to make restored mails show up becomes rather unreasonable. surely there is a better way to do this? I'd be glad for any and all hints! =) best regards silvana -- Empfehlen Sie GMX DSL Ihren Freunden und Bekannten und wir belohnen Sie mit bis zu 50,- Euro! https://freundschaftswerbung.gmx.de

[Dovecot] Dovecot dsync mail replication issues
by Reuben Farrelly 01 May '12

01 May '12

Hi, I'm trying to set up some dsync based replication between two hosts on my network. The current topology is a single server running Postfix with a single dovecot installation with a Maildir per user (only 4 users including myself). No NFS, just local system users on ext4. I am only using system users, ie no virtual users. I am using dovecot deliver to deliver mails into the Maildir's. This - being a very standard Maildir installation - all works just fine. I'm running dovecot-2.1.5 (release versions) x86_64 with Gentoo on both hosts and using key based ssh to transport the data using the root login. What I would like to do is extend the design so as to replicate the Maildirs across a second machine and in the future be able to connect via IMAP into either machine to sync mail. Two way dsync would be rather cool because I could then deliver via SMTP to either system and have changes automagically propagate - but initially just simple replication would be a good start. I was hoping that dsync would allow me to do this, but I've run into quite a number of problems while getting this to work. http://dovecot.org/list/dovecot/2012-March/064243.html ...was very useful and I've based my config on that. Initially I've tried to sync up the user Maildirs, and this has more or less worked: doveadm sync -u lyn remote:root@dustbowl.reub.net This succeeds without error on the initial sync. However if I try to run the re-sync again (such as a use case of if the sync of another Maildir takes 4 hours so I want to resync up the earlier ones again) I end up with a mysteriously named INBOX folder in both the source and destination Maildirs: drwx------ 5 lyn lyn 4096 Apr 30 19:32 .INBOX_7a86a62d465a974fb92f00003b258734 It has the basic structure of a Maildir but is empty in terms of mails: drwx------ 2 lyn lyn 4096 Apr 30 19:32 cur -rw------- 1 lyn lyn 220 Apr 30 19:32 dovecot.index.log -rw------- 1 lyn lyn 51 Apr 30 19:32 dovecot-uidlist -rw------- 1 lyn lyn 0 Apr 30 19:32 maildirfolder drwx------ 2 lyn lyn 4096 Apr 30 19:32 new drwx------ 2 lyn lyn 4096 Apr 30 19:32 tmp First question: why is this random named directory being created in the origin Maildir? Shouldn't the replication be more or less read-only in the origin Maildir? Second question: If I re-attempt a doveadm sync a second time I get this error: tornado Maildir # doveadm sync -u lyn remote:root@dustbowl.reub.net dsync-local(lyn): Error: Can't rename mailbox INBOX_7a86a62d465a974fb92f00003b258734 to INBOX: Target mailbox already exists dsync-local(lyn): Error: Can't rename mailbox INBOX to INBOX_eb15f30ea563be4b703200002bd68bb1: Renaming INBOX isn't supported. tornado Maildir # It's not clear if the second attempt has failed or succeeded, and it's a bit odd that it errors out on a directory that the dovecot sync process itself has created. Third question: Upon starting Dovecot lots of ugliness is logged in the mail log: Apr 30 19:44:59 tornado dovecot: master: Dovecot v2.1.5 starting up (core dumps disabled) Apr 30 19:44:59 tornado dovecot: doveadm(mozsync): Error: user mozsync: Initialization failed: Namespace '': mkdir(/var/www/xxx/server-full/Maildir) failed: Permission denied (euid=1016(mozsync) egid=1016(<unknown>) missing +w perm: /var/www/xxx/server-full, dir owned by 0:0 mode=0755) Apr 30 19:44:59 tornado dovecot: doveadm(mozsync): Error: sync: User init failed Apr 30 19:44:59 tornado dovecot: doveadm(mozsync): Warning: I/O leak: 0x414190 (line 102, fd 16) Apr 30 19:44:59 tornado dovecot: dsync-local(cisco): Error: remote: doveadm(cisco): Fatal: User doesn't exist Apr 30 19:44:59 tornado dovecot: dsync-local(cisco): Error: read() from worker server failed: EOF Users mozsync and cisco are not valid mail users and it's not appropriate that Dovecot tries to create a Maildir for either of them. The users are system unprivileged users only, and do not ever send or receive mail. And - I/O leak? ;) Also, user cisco is local to one box only, and does not exist (nor does it need to) on the remote host. So any complaints about this user are invalid and dovecot needs to ignore replication for this user anyway. Fourth question, upon starting dovecot again, mail.log then spews several hundred of these messages: Apr 30 19:45:06 tornado dovecot: dsync-local(reuben): Error: msg-get failed: box=Trash uid=114863 guid=1335382569.M98089P29952.tornado,S=6479,W=6625 Before aborting entirely with: Apr 30 19:45:09 tornado dovecot: imap: Server shutting down. in=328 out=2042 It seems to me that a a few of those problems logged could be solved by being able to specify which system users to synchronise, rather than Dovecot making a blind assumption that all users actually have valid Maildirs that need to be created, and all need to be sync'd between two hosts. Subsequent delivery based sync'ing fails silently (pending more investigation) but I'd like to try and fix the above listed problems first before worrying about the later stages of the sync not working. Has anyone else run into these problems or found better ways of making this type of setup all work? Thanks, Reuben

[Dovecot] Sieve doesn't find user scripts
by Jochen Spieker 30 Apr '12

30 Apr '12

Hi, I want to use Sieve filtering with my Dovecot 1.2 installation on Debian squeeze. I have a virtual domain setup using Portgresql. ManageSieve works fine so far, I can edit and activate/deactive scripts (using Thunderbird + Plugin) and they show up in the filesystem where I expect them to be, see below. The problem is that LDA doesn't find the script.

[Dovecot] Refiltering mails without loosing flags
by Dieter Knopf 30 Apr '12

30 Apr '12

Hello, is there a way to refilter all mails in a folder without loosing all flags and moving all messages in a different folder? I have >10k mails in my Inbox and need to create new filterrules from time to time. But there is no way to refilter my inbox without moving. Atm i need to move all mails in a folder like "refilter" and then run getmail/... to refilter the mails. It would be really nice to refilter a existing folder and just move mails with hits in the filter list. Thanks Dieter

[Dovecot] setacl fails - does not find dovecot-acl file
by Michael Stilkerich 29 Apr '12

29 Apr '12

Hi, I'm using dovecot 2.0.13 that ships with Ubuntu 11.10. I tried setting up a shared namespace as documented in the wiki to enable the sharing of a mailbox between two users. I have a Maildir(++) directory for each user. Each user has a system account. The Maildir of each user is owned by the user's system account and group read/writable by the group mail (hence mail_access_groups=mail). Relevant parts of my config: mail_plugins = acl mail_location = maildir:/home/dovecot/%u mail_access_groups = mail namespace { type = private separator = / prefix = inbox = yes hidden = no subscriptions = yes } namespace { type = shared separator = / prefix = shared/%%u/ location = maildir:/home/dovecot/%%u:INDEX=/home/dovecot/%u/shared/%%u subscriptions = no list = children } protocol imap { mail_plugins = $mail_plugins imap_acl } plugin { acl = vfile } plugin { acl_shared_dict = file:/home/dovecot/shared-mailboxes } When I try to create an ACL in a telnet session, the command fails with an internal error. The log shows: dovecot: imap(michael): Error: fstat(/home/dovecot/michael/.test/dovecot-acl.lock) failed: No such file or directory dovecot: imap(michael): Error: file_dotlock_open(/home/dovecot/michael/.test/dovecot-acl) failed: No such file or directory The error occurs whether a (manually created) dovecot-acl file exists or not. The dovecot-acl.lock file is created by not removed afterwards. Subsequent setacl commands will timeout waiting for the lock to be released until I delete it manually. If I create the dovecot-acl file manually and provide access to another user, the getacl command will correctly show the permissions and the other user can access the folder. setacl will still fail to modify the acl file, however (same error). Another thing that irritates me is that dovecot seems to use the dotlock locking method, although I explicitly set lock_method to fcntl (also tried flock, same behavior). I'm not using chroot. I appreciate any help to get this sorted out. Thanks, Michael

[Dovecot] help with AES_DECRYPT and password lookup - mysql password_query
by jeep＠rahul.net 29 Apr '12

29 Apr '12

Hello- Sorry if this is a noob question, but I cant seem to get my password_query to work with dovecot + mysql. Im using 'Password verification by SQL server' at: http://wiki2.dovecot.org/AuthDatabase/SQL trying to modify it to work with my encrypted passwords in the DB. Im using the following which isnt working: password_query = SELECT NULL AS password, \ 'Y' as nopassword, userid AS user \ FROM users WHERE userid='%u' AND AES_DECRYPT(password, 'mykey')=password 1. Is it even possible to do this via 'password_query'? 2. If so, what am I doing wrong? Thanks, Jeff /mf/home/jeep/shell/.signature

[Dovecot] Session IDs
by Timo Sirainen 28 Apr '12

28 Apr '12

v2.1.2 added support for "session IDs", which is a 9 year unique identifier for that specific IMAP/POP3 connection. Initially I thought it would only be useful for tracking connections going through Dovecot proxies to backends (the session ID is forwarded), but then I thought it could be useful for everyone if auth process also logs the session ID. So I thought for v2.1.6 I'd change the defaults: a) Failed login: Apr 28 17:37:23 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=XtG7KL6+jQB/AAAB lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=42125 resp=<hidden> Apr 28 17:37:23 auth: Debug: passwd-file(foo,127.0.0.1,<XtG7KL6+jQB/AAAB>): lookup: user=foo file=/usr/local/etc/passwd.imap Apr 28 17:37:23 auth: Info: passwd-file(foo,127.0.0.1,<XtG7KL6+jQB/AAAB>): unknown user Apr 28 17:37:25 auth: Debug: client out: FAIL 1 user=foo Apr 28 17:37:50 imap-login: Info: Aborted login (auth failed, 1 attempts in 27 secs): user=<foo>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured, session=<XtG7KL6+jQB/AAAB> b) Successful login: Apr 28 17:38:27 auth: Debug: client in: AUTH 2 PLAIN service=imap secured session=rNuHLL6+jgB/AAAB lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=42126 resp=<hidden> Apr 28 17:38:27 auth: Debug: passwd-file(tss,127.0.0.1,<rNuHLL6+jgB/AAAB>): lookup: user=tss file=/usr/local/etc/passwd.imap Apr 28 17:38:27 auth: Debug: client out: OK 2 user=tss Apr 28 17:38:27 auth: Debug: master in: REQUEST 1375993857 14321 2 0f2f78deedcb7e38a278cf79819360c5 Apr 28 17:38:27 auth: Debug: passwd-file(tss,127.0.0.1,<rNuHLL6+jgB/AAAB>): lookup: user=tss file=/usr/local/etc/passwd.imap Apr 28 17:38:27 auth: Debug: master out: USER 1375993857 tss uid=1000 gid=1000 home=/home/tss Apr 28 17:38:27 imap-login: Info: Login: user=<tss>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=14338, secured, session=<rNuHLL6+jgB/AAAB> ..

I'm mainly wondering: 1) Does this change break someone's auth log line parsing? 2) Does the auth prefix look prettier with or without <> around session id? :) 3) Anything else I should do about this now that I'm changing it anyway?

[Dovecot] OT but E-Mail related. save a copy off all mail as eml
by Götz Reinicke 26 Apr '12

26 Apr '12

Hi, I'm sorry to bug you with an not directly dovecot related question, but this is for me right now the place with the best mailsystem admins I know. I'm asked if there is a way to save a copy of all mail we send trough our sendmail server (Red Hat EL 5.x) in and out as an .eml file for further processing by a DMS system. The files should be saved on some network share. Any suggestion are welcome and thanks.

[Dovecot] v2.1.5 released
by Timo Sirainen 26 Apr '12

26 Apr '12

http://dovecot.org/releases/2.1/dovecot-2.1.5.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.5.tar.gz.sig A few announcements first: I'm now going to start being more strict about not answering Dovecot questions sent to me privately (especially support requests, but also bug reports, feature requests, etc). Often those questions could be answered by other people in the mailing list as well, so they just waste my time. Even if you're sure that I'm the only person who can possibly answer it, it may be something that others are interested of as well and replying privately denies them the possibility of reading about it. If you really do not want to send something publicly, you still have an option for private communication: just buy one of the Dovecot support packages. This is also the first Dovecot release that has run through automated release testing. I've been planning on doing that for last 5 years at least, and finally it's done. The testing includes running a lot of tests to verify that the IMAP server gives proper responses, stress testing doesn't break it, memory isn't leaked and several other things. The tests are run for many different kinds of configurations. Some bugs show up only for some specific combination of settings, but unfortunately because there's such a large number of them it's impossible to test every combination. So here's another advantage that Dovecot support customers have: they can have their specific configuration included in the automated tests. This release already fixes one bug I found only after testing a customer's config. Oh, and looks like I got accepted as a speaker to LinuxTag 2012. The plan is to talk about some new things in Dovecot and dsync replication (looks like I have to hurry up with the dsync rewrite). And finally, the most important changes since v2.1.4: * IMAP: When neither the session nor the mailbox has modseq tracking enabled, return the mailbox as having NOMODSEQ in SELECT/EXAMINE reply. Old versions in this situation always simply returned HIGHESTMODSEQ as 1, which could have broken some clients. + dict file: Added optional fcntl/flock locking (default is dotlock) + fts-solr: doveadm fts rescan now resets indexes, which allows reindexing mails. (This isn't a full rescan implementation like fts-lucene has.) + doveadm expunge: Added -d parameter to delete mailbox if it's empty after expunging. - IMAP: Several fixes related to mailbox listing in some configs - director: A lot of fixes and performance improvements - v2.1.4 didn't work without a mail home directory set - mbox: Deleting a mailbox didn't delete its index files. - pop3c: TOP command was sent incorrectly - trash plugin didn't work properly - LMTP: Don't add a duplicate Return-Path: header when proxying. - listescape: Don't unescape namespace prefixes.

[Dovecot] LDAP Lookup not returning value in maxStorage
by Bruce, Andrew 26 Apr '12

26 Apr '12

Hi there, We're setting up a Dovecot virtual email setup - we've got everything working perfect with LDAP logins authenticating against AD and so forth, but we're having issues with retrieving the maxStorage value from AD (this is a pre-setup field in AD that we'd like to use to set per user quotas). In our LDAP lookup, we have the maxStorage entry listed under user_attrs for the quota (user_attrs = maxStorage=quota_rule=*:storage=%$M), and in the debug logs, can see it trying to get the entry, but it fails with: Mar 27 13:19:27 auth: Debug: ldap(username(a)site,192.168.1.5): user search: base=dc=site,dc=local scope=subtree filter=(&(objectClass=person)(| (userPrincipalName=username@site) (|(mail=username@site)(samAccountName=username@site)))) fields=maxStorage Mar 27 13:19:27 auth: Debug: ldap(username(a)site,192.168.1.5): no fields returned by the server At this point, we then see the default quota applied. If we change the name of the field from maxStorage to instanceType we see the value show up in the logs and passed through to the quota system and applied successfully: Mar 27 11:09:01 auth: Debug: ldap(username(a)site,192.168.1.5): user search: base=dc=site,dc=local scope=subtree filter=(&(objectClass=person)(| (userPrincipalName=username@site) (|(mail=username@site)(samAccountName=username@site)))) fields=instanceType Mar 27 11:09:01 auth: Debug: ldap(username(a)site,192.168.1.5): result: instanceType(quota_rule=*:storage=%$M)=*:storage=4M Mar 27 11:09:01 auth: Debug: master out: USER 3901227009 username@site quota_rule=*:storage=4M Which seems a bit weird. If we use ldapsearch and pass it the same search string and look for the field maxStorage, we clearly see the field and the value being returned. The result looks the same if we also lookup instanceType. We're using Dovecot 2.0.9. Does anyone have any idea as to why we can't use this field? Thanks, Andrew

Yeah, what he said. Someone helpfully added documentation on how to do this at the end of Dovecot1's wiki (http://wiki.dovecot.org/LDA/Sendmail) which probably should be copied to Dovecot 2's wiki.

[Dovecot] dovecot %u variable problem....
by Kris 26 Apr '12

26 Apr '12

Hi guys n gals, im on an ubuntu 11 VPS on linode (dovecot version 2.013). ive spent a lot of time and googling trying to get postfix, dovecot, ssl, saslauthd and mysql to all play nice together and im quite close now but theres something going on i cant quite explain and id really appreciate some help. I have been going for ten hours on this today and it seems in direct conflict with what dovecot themselves say... the problem is a variable in dovecot (%u) which is normally used as a full username in sql query strings (i.e. user@domain) and is simply dropping the domain for some reason... From dovecot docs (http://wiki2.dovecot.org/Variables) The variables that work everywhere are: %u user full username (e.g. user@domain) so i have postfix and stuff set up ok to send at least and i know this because ive tested it by hard-coding the string in the sql query myself with a successful send... but, anyway, the problem with the '%u' variable is it is doing stuff like this: (from mail.log and mysql.log) localhost dovecot: auth: Debug: sql(admin(a)microhard.com,xx.xx.xx.xx): SELECT home,uid,gid FROM users WHERE id = 'admin(a)microhard.com' this was derived from the following query in /etc/dovecot/dovecot-sql.conf.ext user_query = SELECT home,uid,gid FROM users WHERE id = '%u' so no problem there.... but then this happens when i attempt to send mail and this means the user gets rejected because dovecot cant find the user id in the db without the correct string (i.e. user@domain): localhost dovecot: auth: Debug: sql(admin,xx.xx.xx.xx): query: SELECT id as user, crypt as password FROM users WHERE id= 'admin' Query SELECT id as user, crypt as password FROM users WHERE id= 'admin' which is derived from the following query also in /etc/dovecot/dovecot-sql.conf.ext password_query = SELECT id as user, crypt as password FROM users WHERE id= '%u' and to further confuse me, this 'unchangeable' variable sometimes decides to right itself without any obvious reason... localhost dovecot: auth: Debug: sql(admin(a)microhard.com,xx.xx.xx.xx): query: SELECT id as user, crypt as password FROM users WHERE id= 'admin(a)microhard.com' im wondering if its something to do with my client dropping the domain, or whether dovecot has an error, or some other thing ive overlooked... my dovecot.conf looks a lot like this: # 2.0.13: dovecot.conf # OS: Linux 3.0.18-x86_64-linode24 x86_64 Ubuntu 11.10 ext3 first_valid_uid = 5000 last_valid_uid = 5000 login_greeting = I likes my ducks n geese I do. mail_location = maildir:/var/spool/mail/virtual/%u #enables logging all failed authentication attempts. auth_verbose=yes #enables all authentication debug logging (also enables auth_verbose).

I'm migrating an old UW pop server to a new Dovecot server. The old server did not allow mail to be stored on the server, so only mbox files exist in /var/mail, with nothing in /home/$user. I'd like to copy the /var/mail directory over to the new server and then use dsync to convert the mbox files and put them in /home/$user/Maildir, but every permutation of the command line I've tried dies with a variation on can't find/write either /var/mail/mail or /home/$user/mail, seems it won't deal with mbox files without an associated mail directory. Can dsync be used for this kind of conversion, or should I look elsewhere for conversion utilities? Thanks for helping a noob who can't traverse a wiki without leaving a trail of breadcrumbs. -- Jeff Simmons jeff(a)j-simmons.net Simmons Consulting - Network Engineering, Administration, Security

[Dovecot] 2.1.x changes and dsync -- Wiki suggestion
by Jeff Kletsky 26 Apr '12

26 Apr '12

There are a couple things that show up on the Upgrading/2.1 wiki page that would be useful to have on pages describing dsync (Tools/Dsync, Migration/MailFormat, Tools, perhaps others): * dsync was merged into doveadm * You can't dsync 2.0.x to/from 2.1.x That second point is especially "interesting" to me as it seems that Apple MacOS X Server is still on 2.0.16, at least from what I see on opensource.apple.com. I was planning on migrating mail off the current server onto my friend's new MacMini, but I'll have to figure out how to "downgrade" the mail jail to a 2.0 version, it seems. Thanks for all the great work, Jeff

[Dovecot] Reading Mutt mboxes from Thunderbird
by Leonardo M. Ramé 26 Apr '12

26 Apr '12

Hi, I'm a user of Mutt, and before moving to Thunderbird I'm trying to share mboxes between them. To do this, I installed Dovecot to create an IMAP server in my local machine, to serve mutt mboxes to be read by Thunderbird. So far, I can read my inbox from /var/mail/%u, but in mutt, I have many folders in ~/mail, like 2010-mails, 2011-mails, mailing-list-x, mailing-list-y, and so on. How can I configure Dovecot to read them?. In /etc/dovecot/conf.d/10-mail.conf I have this: mail_location = mbox:~/Mail:INBOX=/var/mail/%u I'm using Ubuntu 11.10, and Dovecot 2.0.13.

[Dovecot] How to remove duplicate GUID messages from storage?
by Daniel Parthey 26 Apr '12

26 Apr '12

Hi, I tried to import messages like this: doveadm import -u username(a)example.org mdbox:/mail/dovecot/example.org/username/mail mbox:/root/mail.txt all This seemed to have imported the same messages in the mail storage, as they were already there. And now I have got a lot of duplicates. Then I deleted the mbox:/root/mail mail stuff from "mailboxes" folder and the storage remained, with duplicate GUIDs. The following command doveadm -v force-resync -u username(a)example.org INBOX outputs lots of messages like this one, with different GUID doveadm(username(a)example.org): Error: mdbox /mail/dovecot/example.org/username/mail/storage: Duplicate GUID 0b8a032d66a0924fb42c0000de5f8128 in m.55:45484041 and m.14:52173045 The messages at m.55:45484041 and m.14:52173045 have the same content, since they were seemingly imported from the mail store itself, they are in the storage twice now and require twice as much disk space as before. How can I manually remove these identical, duplicate messages from the storage to save space? Dovecot does not do it automatically. Kind regards, Daniel

[Dovecot] 2.1.5 problem with mail_location
by postmaster 25 Apr '12

25 Apr '12

I've been advised to set : mail_location = maildir:~/ as the home directory is found through a sql request. this has been working perfectly up to and including 2.1.4 from 2.1.5 however this setting gives cause to a problem : instead of looking in the mail home eg /var/mail/domain/user\@domain/ dovecot is looking for mail in /var/mail/domain/user\@domain/~ the '~' directory is created upon the first request for mail and all future mail transactions in dovecot is done relative to this folder. is this behavior a bug or a feature ??? -- Bjarne D Mathiesen København N ; Danmark ; Europa ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ denne besked er skrevet i et totalt M$-frit miljø MacOS X 10.7.3 Lion ; 2.8GHz Intel Core i7 ; 16GB 1067MHz DDR3

[Dovecot] dsync on large mailbox "fails"
by Jeff Kletsky 25 Apr '12

25 Apr '12

I've been trying to convert an existing set of mbox mail to maildir using dsync, but it seems to fail when it gets to the large boxes. $ dsync -Dv mirror maildir:~/Maildir Everything seems to work reasonably well until the first of the large boxes hits: dsync(jeff): Warning: Maildir /home/jeff/Maildir/.cron.2010-07-10: Synchronization took 1210 seconds (102289 new msgs, 0 flag change attempts, 0 expunge attempts) dsync(jeff): Warning: Transaction log file /home/jeff/Maildir/.cron.2010-07-10/dovecot.index.log was locked for 1210 seconds After this, the doveadm process goes from ~75% of the CPU core utilization to 100% and stays there, even overnight. I've also tried $ dsync -Dv backup maildir:~/Maildir with similar results. While I did see some threads on dsync speed, they seemed to be minutes for a few GB of data, not hours. There is plenty of space on the drive, and, from what I understand, there is not a file-count limit on FreeBSD's ufs (at least not one that I'm anywhere near) Any suggestions? Thanks!
