[Dovecot] selection correct auth with multiple auth methods
by jm 25 Mar '09

25 Mar '09

How do you control which socket or authentication process dovecot's pop3 daemon chooses to use? I've got a user database with two flags one to allow pop3 access and the other to allow the use of auth smtp. There are two authentication instances configed, thus, auth default { .... passdb sql { args = /etc/dovecot-sql-postfix.conf } .... socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = group = } } auth postfix { ..... passdb sql { args = /etc/dovecot-sql-postfix.conf } .... socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } From the logs and testing pop3 is using the postfix authentication instance and not the default as expected. Does anyone out there know how control dovecot's pops daemon authentication choice? This infomation seems to be lacking in the documentation I can find. Jeff.

[Dovecot] Making changes to dovecot log levels
by Thomas M Goerger 24 Mar '09

24 Mar '09

Hi Timo, Awhile back I'd written about making changes to some of the log levels that dovecot writes to to stop the process from writing these to monitor. I wanted to run a few changes by you for this, just to make sure these won't cause problems somewhere else. And to send this to the list, in case anyone else wants to make similar changes in the future. In the file src/lib-index/mail-index.c: duplicate the function mail_index_set_error to mail_index_set_warning and call this function in /src/lib-index/mail_cache.c instead int mail_index_set_error(struct mail_index *index, const char *fmt, ...) { va_list va; i_free(index->error); if (fmt == NULL) index->error = NULL; else { va_start(va, fmt); index->error = i_strdup_vprintf(fmt, va); va_end(va); i_error("%s", index->error); } return -1; } changing the line : i_error("%s", index->error); to i_warning("%s", index_error); and for the file src/lib-storage/index/mbox/mbox-sync.c changing this code if (rec == NULL && uid < sync_ctx->idx_next_uid) { /* this UID was already in index and it was expunged */ mbox_sync_set_critical(sync_ctx, "mbox sync: Expunged message reappeared in mailbox %s " "(UID %u < %u, seq=%u, idx_msgs=%u)", sync_ctx->mbox->path, uid, sync_ctx->idx_next_uid, sync_ctx->seq, messages_count); ret = FALSE; rec = NULL; } else if (rec != NULL && rec->uid != uid) { /* new UID in the middle of the mailbox - shouldn't happen */ mbox_sync_set_critical(sync_ctx, "mbox sync: UID inserted in the middle of mailbox %s " "(%u > %u, seq=%u, idx_msgs=%u)",sync_ctx->mbox->path, rec->uid, uid, sync_ctx->seq, messages_count); ret = FALSE; rec = NULL; from mbox_sync_set_critical( etc... to mail_storage_clear_error(storage) i_warning("Error text"... mail_storage_set_internal_error(storage) to clear and set the storage pointer Hopefully that's all clear. If you have any questions, please let me know.

[Dovecot] Problem with dovecot + imap idle + qmail-local delivery
by Jochen Schug 24 Mar '09

24 Mar '09

Hi, I've recently switched from courier-imap to dovecot. Everything seemed to work fine, but after I while I noticed that dovecot is occasionaly causing problems with delivery of new incoming mails. System: Gentoo Linux, kernel 2.6.19, qmail 1.03, vpopmail 5.4.26 , dovecot 1.1.11, maildir, mail store on ext3. Symptoms: qmail is having trouble with the mail delivery. First I thought it had something to do with vpopmail or dovecot's quota support, but I tracked it down to qmail-local. I tried two different versions, one with Bill Shupp's maildir++ patch and one without. With the patch, I'm getting "User_over_quota._(#5.1.1)" errors. Mail is delivered once and sender is sent a notification about the exceeded quota. Without the patch, I get "Temporary_error_on_maildir_delivery._(#4.3.0)". Mail is delivered, but delivery is tried again and again. This only happens if a MUA is logged in to the mailbox and IMAP IDLE is being used. If the MUA is disconnected: fine. If dovecot is stopped: fine. I tried a couple of different things, all without success: - upgraded dovecot from 1.1.7 to 1.1.11 - compiled a new kernel with inotify support and recompiled dovecot - migrated mail store from reiserfs to ext3 - disabling quota support in dovecot - tried dovecot's various file locking mechanisms Right now I'm working around this by removing IDLE from the capabilities. This solves the problem, but leaves me with a less functional IMAP server. Any help is greatly appreciated.

[Dovecot] Staged migration from mbox to maildir
by Stewart Dean 24 Mar '09

24 Mar '09

So much changes in this migration that the ideal way to do it would be to begin with a few users or a department, then migrate the users affinity group by affinity group: first an institute or so, then the faculty, then the staff, then the students, moving to bigger and bigger groupings as the bugs work out of the migration and the move becomes more assured. We use sendmail and procmail. There's no problem there, as the ~./procmailrc can be changed to over-ride the mbox default until all groups are done and it become the default. The problem comes with IMAP. While dovecot can tell if a folder is mbox or maildir, it has to be pointed to the right place (by namespace definitions in the client, IIRC), and the default of putting the inbox under ~/mail is one I'd like to embrace for various reason...but given that that means moved inbox folders and *that* means either making a global change (there goes staged migration) OR changing the namespace definitions on each PC. I can get to the early few and change the namespaces definition, but there doesn't appear to any equivalent (enlighten me, if I'm missing something) to ~/.procmailrc for imap, so that I don't have to get on the client machine. Is this correct or am I (hopefully) wrong and there *is* a way to change things on the server that allows for staged migration? Oh, I would so like to be wrong!

[Dovecot] Released Sieve v0.1.4
by Stephan Bosch 23 Mar '09

23 Mar '09

Hello Dovecot users, Not much Sieve development was done in the last five weeks, but some important platform-dependent bugs were found and repaired. The main new feature is the addition of a custom Sieve language extension for debugging in the Sieve command line tools. Changelog Sieve v0.1.4: * Started work on the sieve-filter tool. With this command line tool it will be possible to (re-)apply Sieve filters on a mail folder. It is currently undocumented and far from functional. + Added a custom debug extension that provides the possibility to print debug messages from scripts executed by the Sieve tools. - Fixed issue with opening relative paths as a mail file. Bug reported by Ian P. Christian. - Fixed MAC OSX compile problem. Turns out the extern modifier was missing at multiple places. Bug reported by Edgar Fuss. - Fixed Solaris compile problem: removed unecessary and unportable linker flags that caused compile to fail. Bug reported by Andres Yacopino. The release is available as follows: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.4.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.4.tar.gz.sig Have fun testing the new release and don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] Single Instance Storage still on the roadmap?

Hey Timo, I was curious where Single Instance Storage fits in on the roadmap, now that you are maybe settled in in your new digs... Is it still coming soon? Has it been pushed back by your new employers priorities? Its real high on mine, so if has been back-burnered, I'll need to start looking for alternatives... Thanks, -- Best regards, Charles

[Dovecot] update of current quota usage
by floss＠pBartels.info 20 Mar '09

20 Mar '09

Hello, I use Dovecot 1.1.11 and store the current quota usage in a Database. As far I can see it, the quota usage is updated each time dovecot performs an action on a mail. For example if a new mail is stored in the inbox, the current quota usage is increased. If a mail is deleted the quota usage is decreased. If there are still existing E-Mails in the inbox, before quota is turned on or if I perfom changes on the "mail storage" myself (for example purging trash or spam, or something) the current quota usage is NOT updated automatically by dovecot. For example I copy some mailboxes to my server, then the current quota for this mailboxes is still zero. Is it correct that dovecot can't do this for me? If yes, it seems I have to write my own (simple) update script and run it sometimes croned (because I don't really trust the actual quota implementation) and/or I have to update the current quota usage each time I perform actions myself. This "workaround" is easy by using a DB storage, but what about other implementations? Wouldn't it be nice if dovecot could do this or provide a tool for it? Thank you! Philipp

[Dovecot] IMAP ACLs not working

Hi, I've some problems to get folder ACLs working with Dovecot.

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

18 Mar '09

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

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

18 Mar '09

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

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

Delivering works well, I'm just not sure if everyone could revive the emails ? Any tips ? reagards, Sebastian

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

[Dovecot] ACLs are applied recursively to sub mailboxes

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

17 Mar '09

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

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

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

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

16 Mar '09

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

[Dovecot] Mailing list convert scripts not working on wiki
by Phill Edwards 16 Mar '09

16 Mar '09

I'm trying to download Julian Fitzell's scripts to convert mbox to Maildir format from the wiki page at http://wiki.dovecot.org/Migration/MailFormat But when I click on the links for the scripts it just sends me back to the same page rather than downloading the scripts. The links in question are http://wiki.dovecot.org/Migration/MailFormat?action=AttachFile&do=get&targe… and http://wiki.dovecot.org/Migration/MailFormat?action=AttachFile&do=get&targe… How can I get the scripts?

[Dovecot] fstat(mboxname.lock) failed: Bad file descriptor

I have just upgraded from 1.2.beta1 to 1.2.beta2.

Previously with pop3_lock_session = yes, I needed mail_access_group = mail. With the upgrade to beta2, I changed that to mail_privileged_group = mail as shown above. Now, during a session lasting several seconds, I see the following in maillog: Mar 15 09:35:51 sbh16 dovecot: pop3-login: Login: user=<mark>, method=APOP, rip=68.183.193.239, lip=72.52.113.16, TLS Mar 15 09:36:01 sbh16 dovecot: POP3(mark): fstat(mark.lock) failed: Bad file descriptor Mar 15 09:36:04 sbh16 dovecot: POP3(mark): Disconnected: Logged out top=0/0, retr=1/1919972, del=0/328, size=5381253 Mar 15 09:36:04 sbh16 dovecot: child 9023 (pop3) killed with signal 11 (core dumps disabled) This does not occur with shorter sessions lasting only a few seconds or less. The only symptom is the log messages. The client sees nothing unusual, at least in this case where the session is a retrieval of one large message. I haven't tried long sessions retrieving multiple messages. If I remove pop3_lock_session = yes, the issue does not occur. I don't think I need it. I put it in a long time ago to attempt to solve a problem that was actually caused by something else. Since removing it does seem to avoid this issue, I will leave it out, but I'm reporting this anyway as it seems there may be some underlying problem. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

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

15 Mar '09

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

http://dovecot.org/releases/1.1/dovecot-1.1.12.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.12.tar.gz.sig http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta2.tar.gz http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta2.tar.gz.sig I thought I'd do a double-release since it's Friday the 13th. v1.2.0 is getting closer, mainly some ACL fixes left. Changes in v1.2.beta2 since beta1: * Authentication userdb: Renamed system_user to system_groups_user. Probably pretty much no one used this feature. * deliver no longer creates temp files to /tmp. They're instead created to the users' mailbox directories. - IMAP: Fixed SORT command crashing - POP3 was broken in beta1 - Fixes to virtual mailboxes - Fixes to IMAP ACL support Changes in both v1.1.12 and v1.2.beta2: * Added :MAILBOXDIR= to mail_location to specify the root dir for mailboxes. dbox users should migrate to ":MAILBOXDIR=mailboxes", because that's going to be the default in v1.2+. + Linux: Adding -D parameter to login_executable makes login processes dump core to login_dir if they crash. - IMAP: SELECT didn't always return first unseen message in reply - POP3: pop3_lock_session=yes didn't use mail_privileged_group while dotlocking. - mbox: Don't crash if >=8192 bytes long line begins with "From ". - Maildir: More fixes to handling over 26 keywords. - Several logging fixes and improvements - Fixed authentication caching with non-plaintext mechanisms when using a blocking passdb (e.g. MySQL) - Fixed DIGEST-MD5 authentication with user@domain style usernames.

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

14 Mar '09

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

If so, I think the behavior is correct. Maybe change the query to: where username = '%n' and (domain = '%d' or ('%d' = '' and domain is null)) And change all the domain='' to domain=NULL.

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

14 Mar '09

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

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

13 Mar '09

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

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

13 Mar '09

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

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

13 Mar '09

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