[Dovecot] dsync is seriously broken when syncing maildir and mdbox
by interfaSys sàrl 28 Sep '10

28 Sep '10

Hello, I thought mdbox was production ready, but it seems to me that (in 2.0.4) it's quite broken. 1) The documentation only running this to convert from maildir to mdbox: *dsync mirror maildir:~/Maildir* but based on my experience and on posts on the mailing list, it's not enough. A namespace has to be defined and it's not clear whether / or . should be used as a separator. I tried with a dot first and the INBOX folders were empty. It seemed to work better with / 2) After having defined a namespace, running dsync again makes it spit tons of errors Error: Can't rename mailbox INBOX_28c716242e53784cc9030100d3b51c5c to INBOX: Target mailbox already exists Error: Mailboxes don't have unique GUIDs: 4536121fce3ca14cf8c40000d3b51c5c is shared by INBOX and INBOX_4536121fce3ca14cf8c40c Info: INBOX/spam: only in dest Info: INBOX: only in source Each run will create more folders with GUIDs attached to the folder name. 3) Deleting these folders after having moved their content to the properly named ones seems impossible. I see a long list of folders in the bin and when I hit "Empty bin" in Thunderbird, nothing happens. There must must be a caching issue, because if I click on the folder, I'm told these folders don't exist. If I dsync again, I still have conflicts, with folders that are in the bin and then with new copies of INBOX Error: Mailboxes don't have unique GUIDs: 4536121fce3ca14cf8c40000d3b51c5c is shared by INBOX and Trash/INBOX_4536121fce3ca14c Error: Mailboxes don't have unique GUIDs: 4536121fce3ca14cf8c40000d3b51c5c is shared by INBOX_4536121fce3ca14cf8c40000d3b51c5c At that stage, the newly created INBOXes cannot be deleted because they already exist in the bin. I renamed those folders, moved them to the bin, emptied the bin And it's still not fixed when running dsync Error: Mailboxes don't have unique GUIDs: 1a6f000a9751784c12030100d3b51c5c is shared by Sent and Trash/5 Info: Trash_INBOX_bb088f159336a14cc6bf0000d3b51c5c: only in dest Error: Can't rename mailbox INBOX to Trash_3: Renaming INBOX isn't supported. Why can't folder properly be deleted? I never had that problem with Maildir. Cheers, Olivier

[Dovecot] Command to get proxy connection count
by Brad Davidson 28 Sep '10

28 Sep '10

Timo, I'm trying to get a count of active proxy sessions on a given Director. I can of course enable verbose_proctitle and parse the 'N connections' string out of ps output or /proc/pid/cmdline. Is there a better way to do that, perhaps with doveadm? Goes back to needing a command for proxy and director ring status, I guess. -Brad

[Dovecot] Can't delete certain messages
by Karl Davenport 28 Sep '10

28 Sep '10

Running Dovecot version 1.0.10 on Ubuntu Server 8.04 amd64 (ext3). Some users have emails that will not go away. They delete them and the message is moved to the trash folder only to reappear when the mailbox is refreshed. Moving the message manually to another folder has the same effect. We are running Thunderbird as our email client, though I have tried using other clients to remove the messages. Here is my config: # 1.0.10: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s 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 login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no mail_privileged_group: mail mail_location: maildir:/home/%u/Maildir 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 imap_client_workarounds(default): tb-extra-mailbox-sep imap_client_workarounds(imap): tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: passdb: driver: pam userdb: driver: passwd #End dovecot.conf Thanks in advance. -- Karl Davenport WaveCom Communications karl(a)wavecom-it.com 435-656-0972

[Dovecot] mail_fsync=never doesn't work?
by Attila Nagy 28 Sep '10

28 Sep '10

Hello, I've tried to set the above in Dovecot 2.0.3, but according to ktrace (FreeBSD) it still fsync()s a lot (pop3 processes for example). Is this switch useful at all?

[Dovecot] Statistics
by Pierre 28 Sep '10

28 Sep '10

HI list, According to this: http://webcache.googleusercontent.com/search?q=cache:QMGLz9SVNdwJ:www.dovec… << # Use statistics to automatically distribute heavy users to different servers * v1.2 can export very detailed statistics via plugin >> I can't find this "detailed statistics" plugin, I only found this: http://www.dovecot.org/patches/2.0/stats-plugin.c But it only seems to add a "stats" IMAP command. Please can somebody confirm or give me a link to this plugin ? I really need to identify "heavy" users,so this plugin may be really usefull for me. Thanks a lot, Pierre

[Dovecot] Fixed mailbox id?
by Dieter Knopf 28 Sep '10

Hello, I have many Sieve rules and searching for a way to "track" renamings/moving of mailboxes (folders) on my IMAP server. Is there a unique ID for every folder available? I don't think there, i found no ID inside my folders :( If not, it think i need to create a ID-file for every folder and after that i can track the folders and update the rules =) Thanks

Hello, I wanted to improve performance by disabling fsync where I can, but the example in the Wiki is outdated http://wiki2.dovecot.org/MailLocation/LocalDisk # Enable for IMAP/POP3 fsync_disable = yes protocol lda { # Disable for LDA/LMTP fsync_disable = no } Can that simply be replaced by the default config which is mail_fsync = optimized Or should it be replaced by # Enable for IMAP/POP3 mail_fsync = never protocol lda { # Disable for LDA/LMTP mail_fsync = optimized } Cheers, Olivier

[Dovecot] Meaning of mail_max_userip_connections?
by Harald Strack 27 Sep '10

27 Sep '10

Hi, I set mail_max_userip_connections in our IMAP configuration to mail_max_userip_connections = 10 to allow users 10 parallel connections. It seems that this also limits the amount of parallel connections from one IP but different users?! Our users mostly accessing the IMAP server by a webmailer or proxies. Thus, all users (>10000) come from only 5 different IP. However, I got a lot of complaints about denied connections after setting mail_max_userip_connections = 10. Am I right with the meaning of this parameter? Thanks in advance Harry

[Dovecot] inbox doesn't exist, and quota calculation error

Perhaps related to the other errors I just reported, I also see a few of these in the dovecot-2.0.3 logs: lda(pid 8212 user user3): Error: Opening INBOX failed: Mailbox doesn't exist: INBOX lda(pid 8212 user user3): msgid=<201009240906510365.1gj1fpfhrhhm9@mail>: save failed to INBOX: Mailbox doesn't exist: INBOX lda(pid 8212 user user3): Error: BUG: Saving failed to unknown storage and some clients report receiving this IMAP error: tag NO Mailbox doesn't exist: INBOX although in general mail delivery and IMAP work, and these users' Maildir++ directories do exist and look OK.

[Dovecot] password_query, user_query and unrelated userid and emails
by Axel Luttgens 26 Sep '10

26 Sep '10

Let's say one has a SQL table with following fields for John Doe: login: u0007 password: {SHA1}... mailhome: /path/to/joeshome email: john.doe(a)example.com To log in, for internal policy reasons, John MUST make use of his userid "u0007". So, in the password_query, one would need something like: ... WHERE login = '%u' ... On the other hand, for receiving mail thru say, LMTP, one would need something like this in the user_query: ... WHERE email = '%Lu' ... With such a simplistic setup, this works fine: $ doveadm auth u0007 Password: passdb: u0007 auth succeeded but this one obviously fails: $ doveadm user u0007 userdb lookup: user u0007 doesn't exist and one has to do: $ doveadm user john.doe(a)example.com userdb: john.doe(a)example.com home : /path/to/joeshome I can't manage to devise a way to systematically refer to users thru their login, nor to avoid such messages: prefetch(u0007): passdb didn't return userd entries, trying the next userdb There sure must be a way thru adequate "SELECT ... AS ..." clauses. Could someone show me the light? Many, many TIA, Axel

[Dovecot] Settings for unlimited quota for some mailboxes
by Patrick Westenberg 26 Sep '10

26 Sep '10

Hello, I´m using Dovecot 2.0.1 with quota support (quota and imap_quota) which works perfect. However, I´d like to give some mailboxes unlimited quota. What quota setting (in the backend (SLQ)) is needed to tell Dovecot as LDA that the mailbox has unlimited quota? 0 or NULL or -1 or something else? Regards Patrick

[Dovecot] mdbox
by Daniel L. Miller 25 Sep '10

25 Sep '10

Reviewing some mailing list archives and the wiki, I still don't have a real clear picture of why I'd want to use mdbox. What I've taken from the info I've reviewed says mdbox is more complicated (than sdbox), has greater potential for breakage (simply because it's more complex), and has a theoretical performance impact depending on the exact filesystem/hardware used. Was that an accurate summary? Is mdbox something that was desired to solve a particular problem? -- Daniel

I'm running that doveadm command as root, with the -u <user> parameter, where <user> is a virtual user. Anyway, I've just read the wiki2 again, and noted that I don't really need the expire plugin, because it is only needed for the -A option. If I specify the -u parameter, it doesn't utilize the plugin. So I'm now using only the doveadm expunge -u ... command, which now gives me this output: # /usr/local/bin/doveadm -D expunge -u <user> mailbox sa.* SAVEDBEFORE 1d doveadm(root): Debug: Loading modules from directory: /usr/local/lib/dovecot doveadm(root): Debug: Module loaded: /usr/local/lib/dovecot/lib10_quota_plugin.so doveadm(root): Debug: Loading modules from directory: /usr/local/lib/dovecot/doveadm doveadm(root): Debug: Skipping module doveadm_expire_plugin, because dlopen() failed: Cannot load specified object ^^^ I'm curious about this error message.

[Dovecot] LDA + Postfix + LDAP + Sieve (Vacation): Wrong Domain in Reply
by Kendall Gifford 24 Sep '10

24 Sep '10

Hello everyone. I'm running dovecot (1.2.9) with postfix (2.7.0) on an ubuntu 10.04.1. I'm hosting mail for several domains and using the dovecot local delivery agent. Everything has been working great. However, today I set up a sieve script to send out-of-office replies (vacation) for one of our users. I tested it and got the response just fine. However, when looking at the "From" header of the auto-reply, I noticed that the domain name was wrong. My postfix master.cf line for doing local delivery is: dovecot unix - n n - - pipe flags=DRhu user=mail:mail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${nexthop} My LDA configuration is: protocol lda { postmaster_address = postmaster(a)our-primary-domain.com hostname = our-primary-domain.com mail_plugins = sieve quota_full_tempfail = yes deliver_log_format = msgid=%m: %$ rejection_reason = Your message to <%t> was automatically rejected:%n%r } So, our main "administrative" domain is: my-primary-domain.com, the mail server being mail.my-primary-domain.com. I sent an email to a user: janedoe(a)my-other-domain.com and the LDA with Sieve successfully sent me a reply. However, the "From" was: janedoe@mail instead of janedoe@my-other-domain. According to: http://wiki.dovecot.org/LDA/Sieve#Vacation_auto-reply > Vacation uses envelope sender and envelope recipient ... taken from: > ... > V 1.1+ > ... > Envelope recipient: -a parameter to deliver if given, otherwise -d parameter to deliver. If neither is given (delivering to system users), the $USER environment is used. Just for kicks I tried changing my master.cf to use -a instead of -d but then all mail delivers to user "mail" completely breaking all mail delivery. Anyhow, vacation auto-responders are fundamental to operations here and we manage mail for several separate companies. We need the "From" address to reflect the domain of the actual company. I'm stumped as to why sieve isn't getting/using the envelope sender's domain. I'm hoping someone here can point out (a hopefully obvious) mistake. I've attached my four pertinent config files as etc.tgz only slightly scrubbed. Any help is greatly appreciated. -- Kendall Gifford zettabyte(a)gmail.com

[Dovecot] Trouble creating shared virtual folders
by Daniela Silva 24 Sep '10

24 Sep '10

Hi all, I've tried to contact Timo Sirainen by dovecot irc channel but since I couldn't I'm trying the mailinglist. I'm trying to create shared virtual folders, users should not be able either to create or delete a virtual folder. What is the best way to do this? I've tried to do this with virtual mailboxes, but I had problems with permissions, I removed write permissions from folder "virtual_folders" but if I do that dovecot creates "virtual_folders_indexes" without write permissions too, which in this case are needed. I've tried to solve this using ACL but as far as I understood I need an ACL file per folder, which in my case is undoable.

[Dovecot] Unsubscribing from public folders
by aditsu 24 Sep '10

24 Sep '10

Hi, I'm having problems unsubscribing from public folders - nothing seems to happen when I do that (from Thunderbird, Squirrelmail or telnet). I'm using Dovecot 1.2.11. I remember that this worked when I was using version 1.1.7. Here is an extract from an imap session: 3 unsubscribe "Public-NIB/archive/older" 3 OK Unsubscribe completed. 6 lsub "" "Public-NIB/*" * LSUB () "/" "Public-NIB/archive" * LSUB () "/" "Public-NIB/archive/2008b" * LSUB () "/" "Public-NIB/archive/2009a" * LSUB () "/" "Public-NIB/archive/2009b" * LSUB () "/" "Public-NIB/archive/older" * LSUB () "/" "Public-NIB/archive/2010a" 6 OK Lsub completed. And my relevant config: namespace private { separator = / prefix = #location defaults to mail_location. inbox = yes } namespace public { separator = / prefix = Public-NIB/ location = maildir:/(some path) subscriptions = no # v1.1+ } In the meantime I checked and found a "subscriptions" file in my maildir, then went and edited it by hand (and removed the folder I wanted). That seemed to work, and afterwards I can subscribe/unsubscribe to that particular folder, but still not to any other public folders. What could be the problem, or how can I debug this? Thanks Adrian -- View this message in context: http://old.nabble.com/Unsubscribing-from-public-folders-tp29779347p29779347… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Possible to split message store location?
by Edward Carraro 24 Sep '10

24 Sep '10

We have a few dovecot servers all pointing to the same mail location (an NFS mount on a NAS drive). This could lead to a possible bottleneck eventually and we were wondering if it's possible to have dovecot direct x number of users to one message store location while others get their mail on a different mount?

What has changed in 2.0.3 to make dovecot start storing the inbox in a "com" subdirectory of "user@domain"directory in the inbox folder? I am guessing I need to add ":INBOX=/home/mail/%d/%n/mail/" to: mail_location = maildir:/home/mail/%d/%n/mail:CONTROL=/home/mail/control/%d/%n:INDEX=/home/mail/index/%d/%n The inbox was never defined as it automatically put the messages in either "cur" or "new" subdirectories of the "maildir" definition. Because it automatically used subdirectories, it was not a problem for it to use the "maildir" as both the Inbox directory and the directory to hold the other directories created by the user; so, I never defined the inbox. The mysql query is: user_query = SELECT CONCAT('/home/mail/', mailboxes.domain, '/', mailboxes.username, '/') AS home, CONCAT('/home/mail/', mailboxes.domain, '/', mailboxes.username, '/sieve/', mailboxes.username, '.sieve') as sieve, CONCAT('/home/mail/', mailboxes.domain, '/', mailboxes.username, '/sieve/') as sieve_dir, CONCAT('/home/mail/', mailboxes.domain, '/', mailboxes.username, '/mail/') AS maildir, 600 AS uid, 600 AS gid, CONCAT('*:storage=', ROUND(mailboxes.quota/1200), 'M') AS quota_rule, 'Trash:ignore' AS quota_rule2 FROM mail.mailboxes WHERE username = '%n' AND domain = '%d' AND active = '1' iterate_query = SELECT concat(mailboxes.username, '@', mailboxes.domain) AS user, CONCAT('/home/mail/', mailboxes.domain, '/', mailboxes.username, '/') AS home, CONCAT('/home/mail/', mailboxes.domain, '/', mailboxes.username, '/mail/') AS maildir FROM mail.mailboxes I was looking at another thread and saw where the names of dovecot fields, such as "userdb_maildir", have been prefixed with userdb to equal "userdb_maildir". Please Let me know of any changes, or additions, I need to do above. As said, I'm guessing I need to just add ":INBOX=/home/maill/%d/%n/mail/" to dovecot.conf or add ", CONCAT('/home/mail', mailboxes.domain, '/', mailboxex.username, '/mail/') AS INBOX" to the mysql query. Am I correct? Thanks Jerrale G. SC Senior Admin

[Dovecot] Does Director only work with dovecot proxy?

I was reading "conf.d/10-director.conf" and it mentions Dovecot proxy. I've been using perdition in the past for my pop/imap proxying needs and wasn't sure if Director could also use perdition or if it only works with Dovecots proxying. Thanks!

[Dovecot] Creating 'trash' folder
by Jerry 23 Sep '10

23 Sep '10

This might well be OT; however, I thought I would ask anyway. Please keep in mind that the IMAP server is Dovecot. I have a friend who uses Becky Internet Mail <http://www.rimarts.co.jp/becky.htm> on a Windows system. There us an options under the configuration menu in Becky to create the trash folder on the server. It suggest ".trash" for the name. He is aware that I use Dovecot and wanted to know if that would actually work. He claims to have activated that option in Becky; however, the trash folder was never actually created, or at least he was unable to locate it. I was just wondering if anyone had any experience with this sort of thing. I could gather more information, but I doubt that this really has anything to do with Dovecot anyway. -- Jerry ✌ Dovecot.user(a)seibercom.net Disclaimer: off-list followups get on-list replies or get ignored.

[Dovecot] Plain-Text & CRAM-MD5
by Leander S. 23 Sep '10

23 Sep '10

Hi there, I'm currently running my auth against CRAM-MD5 only. But I face problems with customers who apparently have smart phones which ONLY support plain-text authentification ;( Bad - I know, but what should I do ... ;/ So my question now is: Is it possible to run CRAM-MD5 as well as Plain-Text auth together with Postfix if Postfix is using Dovecot's SASL auth service? Cause that's how my setup currently looks like - except the plain-text auth ... Thanks & Regards

[Dovecot] recursive locks
by Mike Abbott 23 Sep '10

23 Sep '10

How can a dovecot-2 plugin safely use file-locks or file-dotlocks when the processes into which it plugs handle multiple connections? (Via, e.g., service imap { client_limit = N service_count = 0 }) Dovecot's file-locks and file-dotlocks do not appear to support nesting/recursion. For instance, squat_trie_lock(). Imagine one user is connected to a single imap process twice.

[Dovecot] Expunged GUID mismatch for UID error
by Xavier Pons 23 Sep '10

23 Sep '10

Hi, we have upgraded from v2.0.1 to v2.0.3 yesterday, trying to solve the "dovecot-uidlist: Duplicate file entry" errors. Now, at the moment, we don't get these errors, but when I try to expunge mails from my trash folder I get a lot of errors: Sep 23 14:24:51 imap1 dovecot: imap(user): Error: Mailbox Trash: Expunged GUID mismatch for UID 20193: 442b5ef0c3d3bf3cf4cb619944dce8e4 vs 0431b9bee05471199fabbc05af3a87a5 (with different GUIDs, and UIDs) and the mails are not expunged from Trash mailbox. Also, I have tried with "doveadm force-resync -u user Trash" and "doveadm expunge -u user mailbox Trash ALL" but not resolve the problem... Thanks Xavier Pons

[Dovecot] Sieve force SSL
by Lukas Haase 23 Sep '10

23 Sep '10

Hi, I have activated only imaps and managesieve. As sieve is running on a different port/protocol: Can I make sure that sieve can ONLY be used with SSL/TLS? As the credentials are transmitted I only offer services with SSL (IMAPS, SMTP over SSL, ...). For sieve I am not sure about this. If there is the possibility that user's credentials are transmitted in plain text I would block the port from the firewall, else I would offer my users the feature to change their rules with their own client (e.g. Thunderbird sieve).

[Dovecot] Sieve error on Quota full (Dovecot 2.0.3)
by Cassidy Larson 23 Sep '10

23 Sep '10

Just switched my storage boxes to 2.0.3 with Pigeonhole. Noticing for those that have quota fulls, my syslog is getting full of errors from sieve: dovecot: lda(user(a)host.com): Error: sieve: script /data/mail/host.com/user(a)host.com//.dovecot.sieve failed with unsuccessful implicit keep (user logfile /data/mail/host.com/user(a)host.com//.dovecot.sieve.log may reveal additional details) Checking the .dovecot.sieve.log I see: sieve: info: started log at Sep 22 00:38:11. error: msgid=<dovecot-1285137490-378260-0(a)storagebox.host.com>: failed to store into mailbox 'INBOX': Quota exceeded ( mailbox for user is full). Any way to suppress these quota full messages from filling up my logs and .dovecot.sieve.log ? I do like the .dovecot.sieve.log for debugging, but regular quota warnings seems excessive. Thanks, Cassidy

[Dovecot] Vpopmail support broken
by Matt Brookings 23 Sep '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 My apologies if I'm posting for information which has already been supplied to the list. I searched and all I found was people talking about the change in 2.0.3, but no details on the commit other than "I was tired of people telling me it crashes". We have not received any reports for the 5.4 or 5.5 branch of vpopmail causing crashes in Dovecot. That being said, if there is a problem, we would like to provide a fix. Again, if details on the specifics of the problem have been supplied, I apologize. Can anyone please provide me some reproduction details for Dovecot 2.0.3's vpopmail plugin compiled against vpopmail 5.4.30+ or 5.5.0? Removing the "vpopmail support broken" line from the configure script, compiling and running seemed to work short-term. I was able to authenticate against the vpopmail plugin. I tested with vpopmail 5.4.32 and 5.5.0 using the cdb authentication module.

[Dovecot] xz compression support
by Attila Nagy 23 Sep '10

23 Sep '10

Hello, Just wondering: Dovecot has gzip/bzip2 compression/decompression support. According to this: http://stephane.lesimple.fr/wiki/blog/lzop_vs_compress_vs_gzip_vs_bzip2_vs_… gzip and bzip2 aren't really useful together. While gzip can offer speed and a reasonable amount of compression ratio, bzip2 is slow, especially on decompression, which Dovecot does more frequently than compression (1 vs many). So: is it planned to include xz (liblzma) support? It would be useful especially for compressing old mails in the background (due to the resource intensity of the compression phase). Thanks,

[Dovecot] "Documentation" link from http://www.dovecot.org/
by William Blunn 22 Sep '10

22 Sep '10

On the Dovecot home page http://www.dovecot.org/ we have a link "Documentation" which links to the Dovecot 1.x wiki ( http://wiki.dovecot.org/ ). There is a question mark in my mind as to whether that is a good idea considering as how the current stable version of Dovecot appears to be 2.0.x. In the Dovecot 1.x wiki, there is a pink stripe across the top of the page which says that the documentation is for Dovecot 1.x. It looks as though the intention was to make that prominent so as to guide visitors to the right documentation, and I think to a certain extent it may work. But I am wondering if perhaps the stripe could be too easily missed. People might start browsing around in the Dovecot 1.x wiki without it even occurring to them that there was a whole another wiki for 2.x. I have an idea: Perhaps the "Documentation" link on the home page could be re-worked to something like Documentation v2.x v1.x where "v2.x" and "v1.x" are links to the two wikis. This would make it obvious that there was different documentation available for v2.x and v1.x, and encourage visitors to choose the appropriate set. Bill

[Dovecot] service(imap-login): chiled ... killed with signal 11

22 Sep '10

Hi, dovecot 2.0.3 After closing the imap(s) connection dovecot crashes: imap-login: Info: Aborted login (no auth attempts): rip=... lip=... mpid=0 master: Error: service(imap-login): child 18636 killed with signal 11 (core not dumped - set service imap-login { drop_priv_before_exec=yes }) master: Warning: Killed with signal 15 (by pid=18643 uid=0 code=kill) It also happens if I only telnet to the imap(s) port and give the only command "1 logout". How can I get a dump for backtracing? With drop_priv_before_exec=yes I get a config error: doveconf: Fatal: Error in configuration file /usr/dovecot/etc/dovecot/dovecot.conf: service(imap-login): drop_priv_before_exec=yes can't be used with chroot As user I can login and work normaly but I have to reconnect after a differnet connection will be closed causing a dovecot crash. Additional information: Solaris 10, packages openssl, openldap by opencsw I had seen a similar error during login process already with an rc-version. Because opencsw offers only an older version of openssl I installed current versions of openssl and openldap, So it works again. Now both packaged are up to date at opencsw. So I would like using these packages again when I install dovecot. Any hints? -- Mit freundlichen Gruessen --- Burckhard Schmidt

[Dovecot] Support for spaces in plaintext passwords?
by Simon 22 Sep '10

22 Sep '10

Hi! I have problems with my cellphone. It does not seem to quote the strings to the login command. I can logon using ie SquirrelMail but if i try to login using AndroidMail it just says "autentication failed". If i try maualy i get similar results. Changing password for test to "password-" a login test password- a OK Logged in. Changing password for test to "password " * OK Dovecot ready. a login test password #here i type "password ", but without "" a NO Authentication failed. Uppon examining squirrelmails comunication it sends login "test" "password " I will of cause file a bugreport that Android Mail should use quoted strings when using 'login' autentication as per rfc2060 (which seems to allow it but not demand it). But i wonder if it is possible to work around this issue in Dovecot somehow?

[Dovecot] expire_tool trouble + howto part sasl from 1.1.7 -> 2.0.1?
by Igor Kowalski 21 Sep '10

21 Sep '10

Hello! Let me smuggle 2 questions in 1 email: 1) I upgraded from 1.1.7 to 2.0.1, but couldn't get it to work, because the 'dovecot + postfix sasl howto' doesn't seem to be updated and the old sasl settings are incompatible with new version. How do I set up sasl with dovecot2 ? Is there any updated howto available? 2) In dovecot 1.1.7: my expire_plugin seems to work fine, new entries are correctly added to the dictionary, but the messages don't actually get expunged. expire_tool says: dovecot --exec-mail ext /usr/lib/dovecot/expire-tool --test Info: maildir: data=~/Maildir Info: maildir++: root=/home/virtual/<domain>/<user>/Maildir, index=, control=, inbox=/home/virtual/<domain>/<user>/Maildir Info: <user>@<domain>/Trash: timestamp 1285005106 (Mon Sep 20 18:51:46 2010 ) -> 1290102903 (Mon Sep 20 18:51:46 2010 ) Info: <user2>@<domain>/Trash: stop, expire time in future: Sat Nov 6 18:33:12 2010 Messages are only updated in the dictionary, but nothing is ever expunged.

Because trash can be called wastebasket for example, and then it doesn't work. Spam can be called Junk, and again, it doesn't work. Any response to these queries would be greatly appreciated.

[Dovecot] MD5 to CRAM-MD5 password conversion?
by David Jonas 21 Sep '10

21 Sep '10

We have a plethora of accounts for which we would like to enable CRAM-MD5 but their passwords are stored as MD5 hashes. Is there anything we can do? Can we take a linux MD5 hashed password (e.g. $1$fac330ee$wd6Tll...) and convert it to dovecot's CRAM-MD5 format (e.g. {CRAM-MD5}b3f297...)? Thanks!

[Dovecot] understand the struct message_header_line
by Alex Baule 21 Sep '10

21 Sep '10

Timo... Using the src/lib-mail/test-istream-header-filter.c as example, and following your tips to jump my desired header value, but i need to store the value from the Header filtered. In the Exemple, the callback is this: static void filter_callback(struct message_header_line *hdr, bool *matched, void *context ATTR_UNUSED) { if (hdr != NULL && hdr->name_offset == 0) { /* drop first header */ *matched = TRUE; } } What i try to understand is how the structs work, it's save the entire header or every line from header call the callback function ? hdr->name_offset is the size of elements in the struct ? (like a array of message_header_line) The void *context ATTR_UNUSED i can pass what i want to change ? like a pointer to a variable ?

[Dovecot] tags disappear in Thunderbird
by Iv Ray 21 Sep '10

21 Sep '10

We have - Dovecot 1.0.15 (the default on Debian Lenny stable) Thunderbird 3.1.4 In our installation the Inbox is a mbox and the other folders are maildir. When we tag messages in Inbox, the tags disappear after a while. In the other folders they stay. I found two possible solutions suggested - 1. Set mbox_lazy_writes=no 2. Convert the Inbox to maildir What would be the best approach in your opinion? Would suggest not following the Debian Lenny stable version (1.0.15), but compiling the current stable Dovecot? Thank you very much, Iv

Hello - I am trying to migrate my dovecot installation from an older server running version 1.x to the latest 2.0.3 When I run configure --with-vpopmail, it bombs pretty quick as follows: ./configure --with-vpopmail checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for a thread-safe mkdir -p... /bin/mkdir -p checking for gawk... gawk checking whether make sets $(MAKE)... yes checking whether to enable maintainer-specific portions of Makefiles... no configure: error: vpopmail support is broken. fix it or access its db another way. however, vpopmail seems to be working fine, i can add domains from vpopmail/bin/vadddomain and they show up in the database just fine. So why do I receive this error and how can i troubleshoot? thank you very much in advance, Joe

[Dovecot] dovecot-2.0.3 - can not upload message, over quota
by LEVAI Daniel 20 Sep '10

20 Sep '10

Hi! I've upgraded to 2.0.3 from 1.2, and it is so far so good. I especially like the new doveadm tool. I have only one tiny problem: Every time I try to upload a message to the server (eg. to a 'Sent' folder, while sending a message), it fails with an error saying I'm over my quota.

[Dovecot] v2.0.3 released
by Timo Sirainen 20 Sep '10

20 Sep '10

http://dovecot.org/releases/2.0/dovecot-2.0.3.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.3.tar.gz.sig * dovecot-lda: Removed use of non-standard Envelope-To: header as a default for -a. Set lda_original_recipient_header=Envelope-To to returns the old behavior. + Added support for reverse quota warnings (i.e. when quota goes back under the limit). This is enabled by adding '-' to beginning of quota_warning value. Based on patch by Jeroen Koekkoek. + dovecot-lda: Added lda_original_recipient_header setting, which is used for getting original recipient if -a isn't used. + dovecot-lda: Added -r parameter to specify final recipient address. (It may differ from original address for e.g. aliases.) + Maildir: uidlist file can now override message's GUID, making it possible for multiple messages in a mailbox to have the same GUID. This also fixes dsync's message conflict resolution. - dovecot-lda: If destination user isn't found, exit with EX_NOUSER, not EX_TEMPFAIL. - dsync: Fixed handling \Noselect mailboxes - Fixed an infinite loop introduced by v2.0.2's message parser changes. - Fixed a crash introduced by v2.0.2's istream-crlf changes.

[Dovecot] replace istream and unref the old one...
by Alex Baule 20 Sep '10

20 Sep '10

I Build a plugin, that do some stuffs with a email. To get the input istream, i use the "get_stream" function, like zlib does. I create a concat_stream, with the full_input[3]; struct istream *full_input[3]; //this like zlib input = imail->data.stream; //first input, using the input full_input[0] = i_stream_create_header_filter(input, HEADER_FILTER_EXCLUDE | HEADER_FILTER_NO_CR, exclude_headers, 1, filter_callback, imail); // second input from another file. full_input[1] = i_stream_create_fd(fd1, 0, TRUE); // finish the input full_input[2] = NULL; // recreating the stream imail->data.stream = i_stream_create_concat(full_input); //unref the old one. i_stream_unref(&input); return index_mail_init_stream(imail, hdr_size, body_size, stream_r); I do like zlib, but i got this errors in LOG. I Think it's because something in the unref, but o don't know what.

[Dovecot] Dovecot 2.0.3
by Matthias Quernheim 20 Sep '10

20 Sep '10

I upgraded today to from 1.2.12 to Dovecot 2.0.3 with the dbox format. I just figured out there are still mail in some users directories with the maildir format. These mail are not displayed at all. Nether with roundcube nor with Thunderbird. How could I convert the remaining maildir mails to dbox? Thanks Matthias

[Dovecot] send HUP when rotating log?
by LEVAI Daniel 20 Sep '10

Hi! Is it necessary for Dovecot2 to send it a SIGHUP when I rotate its log files? I'm asking because then I must turn off the 'shutdown_clients' option, because then every user gets disconnected while rotating the logs.

[Dovecot] Change in delivery directory during 2.0.2->2.0.3 upgrade
by Jeffrey Rice 19 Sep '10

19 Sep '10

In upgrading from 2.0.2 to 2.0.3, Dovecot deliver has started putting new emails into user@host/.user@host/new instead of user@host/new. This change was reversed by downgrading to 2.0.2, so it's due to the minor version change.

[Dovecot] mbox vs maildir
by Jim Pazarena 18 Sep '10

18 Sep '10

I've had clients 'request' nested folders, and it would seem that maildir is designed with that ability while with mbox it is difficult and.or impossible to implement (nested can be achieved; but not nested AND populated in each nest level). My question is, is one format 'better' than the other? It would take a fair bit of time to convert my system to maildir and I would want to feel comfortable that this would be a true 'upgrade' in abilities, rather than simply a change to accommodate nested folders. Thanks,

[Dovecot] moving 1.2.13 system to another hard drive
by Paul Scott 18 Sep '10

18 Sep '10

Hi, I am not very experienced with Dovecot (1,2,13) installed on Debian sid. I have just set up a new system on a new hard drive on the same computer. fetchmail is correctly putting mail in /var/mail/<username>. I have copied my entire Maildir directory from the old hard drive. I have made what changes I understood to dovecot.conf. Dovecot was working on the other drive even though I'm not completely sure how I got it working before. Any ideas for debugging this certainly simple problem for some of you. TIA, Paul Scott

[Dovecot] Too stupid for sieve (former maildrop user)
by Dieter Knopf 18 Sep '10

18 Sep '10

Hello, I just migrated from Postfix/Courier/Maildrop to Postfix/Dovecot/Deliver/Sieve and don't unterstand the right syntax for sieve :( I searched and found many small examples and many links to the RFC, but nothing was usefull for me (or i didn't unterstand it) I installed the latest Dovecot-Sieve (hg). Examples from my maildrop config: # Filter FROM if($E =~ /name(a)domain1\.tld/) { to "$M/.Friends.Name1/" } # Filter FROM with OR if($E =~ /name1(a)domain1\.tld/ || $E =~ /name2(a)domain2\.tld/) { to "$M/.Friends.Name2/" } # Filter Mailinglists if (/^List-Id: .*<sylpheed\.sraoss\.jp>/) { to "$M/.ML.Sylpheed/" } # Filter FROM AND SUBJECT if($E =~ /fname(a)domain.tld/ && /^Subject: *foooooo/) { to "$M/.foo/" } # Filter TO if (hasaddr("name(a)domain.tld")) { to "$M/.foo/" } # Or something like this: if($E =~ /.*(a)facebookmail\.com/) { if (/^Subject: .*invited you to join the group/) { to "$M/.Facebook.Invites.Groups/" } if (/^Subject: .*invited you to the event/) { to "$M/.Facebook.Invites.Events/" } } $E was a shortcut for (adressmatching): ADDR=getaddr($MATCH) E=`echo $ADDR | sed 's/^M//'` $M was the path to the maildir, like /home/vmail/domain.tld/name Is that possible? Or is maildrop simple more powerful? Thank you :-) Dieter

Does this really work with IMAP clients? A namespace prefix must not start with hierarchy separator. My guess is that the crash happens because of it. I think I'll add code to give an error if it's tried.

[Dovecot] dsync to move from 1.2 to 2.0
by Daniel L. Miller 17 Sep '10

17 Sep '10

I'm not certain of the correct syntax for this - and I'm reluctant to risk my live data by experimenting. I've setup a 2.0.2 server on a virtual machine, and I want to copy a live account over to it for testing. Not that it should matter, but the 1.2 machine is using maildir and I want to give sdbox a try on 2.0.2. I'm assuming (dangerous, I know) I should run dsync on the new 2.0.2 machine, and connect remotely to the 1.2. If it matters, my usernames are complete mail addresses, i.e. myname(a)mydomain.com, and are stored as /var/mail/domain/name/Maildir. Does dsync perform an imap connection to the remote server to pull the mails? Or am I confusing this with imapsync? -- Daniel

[Dovecot] sent-mail
by dhottinger＠harrisonburg.k12.va.us 17 Sep '10

Im trying to nail down an issue with some users sent-mail. I have had a few users complaining that their emails are not being copied to their sent-mail folder. Im not sure how widespread it is, mainly because most people dont check their sent-mail. Im running Dovecot version 1.0.7, and yes I know its outdated, but I have had zero problems thus far. Im grepping through my logfiles and dont see any error messages to indicate that there are any issues anywhere on the mailserver. Has anyone else seen any issues with sent-mail not being copied? If checked permissions on the folders and they look correct. thanks, ddh -- Dwayne Hottinger Network Administrator Harrisonburg City Public Schools "Everything should be made as simple as possible, but not simpler." -- Albert Einstein "The hottest places in Hell are reserved for those who, in times of moral crisis, preserved their neutrality." -- Dante

[Dovecot] dsync - how to speed up
by Burckhard Schmidt 17 Sep '10

17 Sep '10

Hi, I have converted some mbox mailboxes to maildir. Inbox and folders had been cpopied before into a separate directories "old-home" and old-inbox onto the new server (dovecot 2.0.2. with fix hg.dovecot.org/dovecot-2.0/rev/14a6e526900d) dsync -v -u user mirror mbox:/old-homehome/~user:INBOX=/old-inbox/user It works but it lasts "very long" time. For one mailbox with 2,4 Gb and nearly 200.000 emails it lasts 100 minutes. I would like to migrate 1.500 Gb - not possible in that way I think. Are there any possibilities making it faster? May be not to generate indices, ..., which could be done later during a first access by the user? Is it possible to run several dsync commands at the same time, of course each one for a different user? (Ressources cpu and I/O system are available.) -- Mit freundlichen Gruessen --- Burckhard Schmidt

[Dovecot] fts plugin - purpose of get_last_uid() ?
by Per Jessen 17 Sep '10

17 Sep '10

It looks like the uid returned is only used as an indication of whether the maildir is fully indexed or not, is that correct? In my setup, the index is built externally and will _always_ be up-to-date. Getting the last uid would mean running a query, which, whilst inexpensive, seems unnecessary if my understanding of the purpose of get_last_uid() is correct. thanks Per Jessen, Zürich

The imap process gets stuck at 100% cpu usage and dovecot.index.search is never touched. I traced the problem to a message (attached) for one of the problematic mailboxes. Also attached are a full backtrace and the output of dovecot -n. The problem is reproducible: step 1) /usr/libexec/dovecot/imap step 2) . select Junk step 3) . search body sometext

[Dovecot] Can solaris sendmail use dovecot lda
by Jürgen Obermann 17 Sep '10

17 Sep '10

Hello, on a Solaris 9 system with dovecot 1.2.14 installed I want to replace the sendmail local delivery agent 'mail.local' with the dovcot LDA. The wiki page http://wiki.dovecot.org/LDA/Sendmail did not really help me, because there are only linux specific tipps I am not able to apply to solaris sendmail.cf. So how can I tell solaris sendmail to use dovecots LDA instead of mail.local?

[Dovecot] dsync: mbox to maildir
by Burckhard Schmidt 17 Sep '10

17 Sep '10

Hello, I started converting INBOX and folder from mbox to maildir. The old folders comming from Dovecot 1.0.13 with a mail_location mbox:%h:INBOX=/inbox/%u. The new instalation on a different server is Dovecot 2.0.1, mail-location maildir:~/maildir:INDEX=/addons/index/%u: CONTROL=~/control:LAYOUT=fs No user has logged in before. I have copied tho old Inbox and folders into /mailstore1/import-inbox and /mailstore1/import-home to the new server. my dsync command dsync -v -u account mirror mbox:/mailstore1/import-home/~account:INBOX=/mailstore1/import-inbox/account This works fine. But there are some problems too: 1. autocreate The plugin autocreate = AutoCleanSpam is activated for lda and imap. There is no user with such folder. dsync ceates two: dsync(account): Info: AutoCleanSpam: only in source dsync(account): Info: AutoCleanSpam: only in dest I saw AutoCleanSpam and AutoCleanSpam_73fc7f01efa3804cb4290000b68194d6, both empty. I deletet it with doveadm mailbox delete -u account -s "AutoCleanSpam_73fc7f01efa3804cb4290000b68194d6" Furthermore I have had before autocreate = Sent ( and some more) If the user has such a folder then again two folders are created, "Sent" which is empty and "Sent_any characters" like above. This folder contains the emails of the old folder Sent. 2. missing skip_broken_mailboxes, skip_dotdirs dsync reports errors like Error: Failed to sync mailbox xyz: Mailbox isn't a valid mbox file After a few minutes dsync stops. Or a file like .mlbxlsttmp causes the same error. I remembered my tests with convert-tool (dovecot-V1.2.12) and could use skip_broken_mailboxes skip_dotdirs. That was fine and I'm missing it. I will have to convert several thousands of users. May be I have to clean their folders before? 3. empty folder I have seen some empty folders. These have not been generated by dsync. Some user could missing them? On ballance dsync converts 10 Gb of mbox to maildir successfully. -- Regards - Burckhard Schmidt

[Dovecot] (Single instance) attachment storage
by Timo Sirainen 17 Sep '10

17 Sep '10

Now that v2.0.0 is only waiting for people to report bugs (and me to figure out how to fix them), I've finally had time to start doing what I actually came here (Portugal Telecom/SAPO) to do. :) The idea is to have dbox and mdbox support saving attachments (or MIME parts in general) to separate files, which with some magic gives a possibility to do single instance attachment storage. Comments welcome. Reading attachments ------------------- dbox metadata would contain entries like (this is a wrapped single line entry): X1442 2742784 94/b2/01f34a9def84372a440d7a103a159ac6c9fd752b 2744378 27423 27/c8/a1dccc34d0aaa40e413b449a18810f600b4ae77b So the format is: "X" 1*(<offset> <byte count> <link path>) So when reading a dbox message body, it's read as: offset=0: <first 1442 bytes from dbox body> offset=1442: <next 2742784 bytes from external file> offset=2744226: <next 152 bytes from dbox body> offset=2744378: <next 27423 bytes from external file> offset=2744378 27423: <the rest from dbox body> This is all done internally by creating a single istream that lazily opens the external files only when data is actually tried to be read from that part of the message. The link paths don't have to be in any specific format. In future perhaps it can recognize different formats (even http:// urls and such). Saving attachments separately ----------------------------- Message MIME structure is being parsed while message is saved. After each MIME part's headers are parsed, it's determined if this part should be stored into attachment storage. By default it only checks that the MIME part isn't multipart/* (because then its child parts would contain attachments). Plugins can also override this. For example they could try to determine if the commonly used clients/webmail always downloads and shows the MIME part when opening the mail (text/*, inline images, etc). dbox_attachment_min_size specifies the minimum MIME part size that can be saved as an attachment. Anything smaller than that will be stored normally. While reading a potential attachment MIME part body, it's first buffered into memory until the min. size is reached. After that the attachment file is actually created and buffer flushed to it. Each attachment filename contains a global UID part, so that no two (even identical) attachments will ever contain the same filename. But there can be multiple attachment storages in different mount points, and each one could be configured to do deduplication internally. So identical attachments should somehow be stored to same storage. This is done by taking a hash of the body and using a part of it as the path to the file. For example: mail_location = dbox:~/dbox:ATTACHMENTS=/attachments/$/$ Each $ would be expanded to 8 bits of the hash in hex (00..ff). So the full path to an attachment could look like: /attachments/04/f1/5ddf4d05177b3b4c7a7600008c4a11c1 Sysadmin can then create /attachment/00..ff as symlinks to different storages. Hashing problems ---------------- Some problematic design decisions: 1) Hash is taken from hardcoded first n kB vs. first dbox_attachment_min_size bytes? + With first n kB, dbox_attachment_min_size can be changed without causing duplication of attachments, otherwise after the change the same attachment could get a hash to a different storage than before the change. - If n kB is larger than dbox_attachment_min_size, it uses more memory. - If n kB is determined to be too small to get uniform attachment distribution to different storages, it can't be changed without recompiling. 2) Hash is taken from first n bytes vs. everything? + First n bytes are already read to memory anyway and can be hashed efficiently. The attachment file can be created without wasting extra memory or disk I/O. If everything is hashed, the whole attachment has to be first stored to memory or to a temporary file and from there written to final storage. - With first n bytes it's possible for an attacker to generate lots of different large attachments that begin with the same bytes and then overflow a single storage. If everything is hashed with a secure hash function and a system-specific secret random value is added to the hash, this attack isn't possible. I'm thinking that even though taking a hash of everything is the least efficient option, it's the safest option. It's pretty much guaranteed to give a uniform distribution across all storages, even against intentional attacks. Also the worse performance isn't probably that noticeable, especially assuming a system where local disk isn't used for storing mails, and the temporary files would be created there. Single instance storage ----------------------- All of the above assumes that if you want a single instance storage, you'll need to enable it in your storage. Now, what if you can't do that? I've been planning on making all index/dbox code to use an abstracted out simple filesystem API rather than using POSIX directly. This work can be started by making the attachment reading/writing code use the FS API and then create a single instance storage FS plugin. The plugin would work like: open(ha/sh/hash-guid): The destination storage is in ha/sh/ directory, so a new temp file can be created under it. The hash is part of the filename to make unlink() easier to handle. Since the hash is already known at open() time, look up if hashes/<hash> file exists. If it does, open it. write(): Write to the temp file. If hashes/ file is open, do a byte-by-byte comparison of the inputs. If there's a mismatch, close the hashes/ file and mark it as unusable. finish(): a) If hashes/ file is still open and it's at EOF, link() it to our final destination filename and delete the temp file. If link() fails with ENOENT (it was just expunged), goto b. If link() fails with EMLINK (too many links), goto c. b) If hashes/ file didn't exist, link() the temp file to the hash and rename() it to the destination file. c) If the hashed file existed but wasn't the same, or if link() failed with EMLINK, link() our temp file to a second temp file and rename() it over the hashes/ file and goto a. unlink(): If hashes/<hash> has the same inode as our file and the link count is 2, unlink() the hash file. After that unlink() our file. One alternative to avoid using <hash> as part of the filename would be for unlink() to read the file and recalculate its hash, but that would waste disk I/O. Another possibility would to be to not unlink() the hashes/ files immediately, but rather let some nightly cronjob to stat() through all of the files and unlink() the ones that have link count=1. This could be wastefully inefficient though. Yet another possibility would be for the plugin to internally calculate the hash and write it somewhere. If it's at the beginning of the file, it could be read from there with some extra disk I/O. But is it worth it?.. Extra features -------------- The attachment files begin with an extensible header. This allows a couple of extra features to reduce disk space: 1) The attachment could be compressed (header contains compressed-flag) 2) If base64 attachment is in a standardized form that can be 100% reliably converted back to its original form, it could be stored decoded and then encoded back to original on the fly. It would be nice if it was also possible to compress (and decompress) attachments after they were already stored. This would be possible, but it would require finding all the links to the message and recreating them to point to the new message. (Simply overwriting the file in place would require there are no readers at the same time, and that's not easy to guarantee, except if Dovecot was entirely stopped. I also considered some symlinking schemes but they seemed too complex and they'd also waste inodes and performance.) Code status ----------- Initial version of the attachment reading/writing code is already done and works (lacks some error handling and probably performance optimizations). The SIS plugin code is also started and should be working soon. This code is very isolated and can't cause any destabilization unless it's enabled, so I'm thinking about just adding it to v2.0 as soon as it works, although the config file comments should indicate that it's still considered unstable.

[Dovecot] Dovecot upgrades break Blackberry instant email (BIS)
by interfaSys sàrl 17 Sep '10

17 Sep '10

Hello, Just like when upgrading to 1.2, upgrading to 2.0.1 confuses RIM's BIS servers and users don't have instant email anymore on their Blackberrys. Under normal conditions, the BIS servers keep one open connection per email account with Dovecot. They're using IMAP IDLE to monitor changes and push them to devices very quickly. After an upgrade, all changes. The BIS servers can't maintain an idling connection anymore, they just poll the Dovecot server when they feel like it (every 2-15 minutes). There is one way to fix this on the devices: The users have to re-create the email account. I don't find this very convenient and was wondering if there was something that could be done on the Dovecot side? Last time it happened, I tried clearing the indexes and resetting file permissions, but nothing helped. Cheers, Olivier

[Dovecot] SSL stops working after server upgrade
by "Ing. Daniel Rozsnyó" 17 Sep '10

17 Sep '10

Hello, after an upgrade of the dovecot server, I can not use SSL connections. Can you help me solving the issue? When googling for the error, there is an opinion that the client is broken (in my case Thunderbird, 3.1.3), but I rather see the issue in the server, because I was upgrading my gentoo box by hand, and the secure imap stopped to work after that. Is there a more verbose SSL logging than the default verbose ssl = yes? It's output is attached below. Also, maybe only a configuration detail is missing, since with this version of dovecot, the configuration files were broken into several smaller files, but for my first look they contained the options I had used before. Thanks.

[Dovecot] [DC2.x ]pop3-login seg faults when compiled with gcc 4.5.2 and gold
by interfaSys sàrl 17 Sep '10

17 Sep '10

Hello, On FreeBSD, Dovecot 2.0.1 compiles fine with gcc45 and the other services have no problem, but even without any optimizations (CFLAGS) at all, pop3-login seg faults when a user tries to connect to Dovecot using POP3. As this is not the only application that has a problem with the latest version of gcc (mod_php), there may be nothing that can be done on the Dovecot side, but I thought I would mention it, in case it was due to some bug in the pop3-login code. Cheers, Olivier

[Dovecot] dovecot as exchange server?
by Jacek Osiecki 16 Sep '10

16 Sep '10

Hi, This might be a stupid question, since my knowledge about Exchange is really poor... Since I've got iPhone, I have noticed that IMAP mailbox support is quite crippled in this device - in comparison to Exchange mailboxes... As I assume that it would be easier to convince Bill Gates to install linux than to convince Steve Jobs to change anything in his "perfect phone", I started searching for something that could serve emails similarly to Exchange. Since gmail provides Exchange access, and they definitely don't run a single huge MS Exchange server, I assume that it is somehow possible to implement Exchange protocols - or am I wrong? So, finally - if it is possible to use Exchange protocol, would there be any plans for implementing it in dovecot? Best regards, -- Jacek Osiecki joshua(a)ceti.pl GG:3828944

[Dovecot] dsync mirror duplicates problem
by Waldemar W. 16 Sep '10

16 Sep '10

Im trying to sync 2 mailserver with dsync mirror functionality. Problem occurs when mails arrive in the same folder on both sides then dsync sometimes runs into problems and duplicates that entrys on both side(2mails then with same content). After running again the same happens again(now 4 mails with same content on every side). And then duplicates this mails on both sides on every run :( Anyone with same problem or is something that could cause this? I tried dsync with and without -f option but no change. Im running dovecot 2.0.1 together with dovecot sieve (latest hg version). thanks, Waldemar

[Dovecot] Sieve problems - compiled script does not get updated
by aditsu 16 Sep '10

16 Sep '10

Hi, I'm using Dovecot 1.1.7 with sieve and managesieve, and Thunderbird with the sieve plugin (0.1.10). Sieve filters are generally working, but I noticed a situation where a script wrongly remains in effect. Here's how to reproduce the problem: - write 2 sieve scripts (in Thunderbird), say A and B, triggered by different things - activate script A and send an email that triggers it (so that it gets compiled) - change the active script to B (by clicking its "active" icon in the list) - send an email that triggers B; it will not work - send an email that triggers A; it will still work The only way I found to fix it is to hunt down the corresponding .dovecot.sievec file and delete it (the .dovecot.sieve symlink gets updated correctly, but .dovecot.sievec doesn't). After deleting it, the correct script is compiled and executed. Is this problem fixed in a newer version of dovecot? Thanks Adrian -- View this message in context: http://old.nabble.com/Sieve-problems---compiled-script-does-not-get-updated… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] sieve rules quiestion (deduplicate e-mails)
by Vasiliy G Tolstov 16 Sep '10

16 Sep '10

Hello. I'm successful use sieve for filtering e-mail from various subscriptions. But if i have subscription for 2 or more mailing lists and user write email to list1(a)xxx.org and list2(a)yyy.org by REPLY TO ALL or make a CC header, i'm recieve email twice, if i reply in some list to user and user REPLY TO ALL - i'm recieve email 3 times :) How can i'm eliminate this duplications? For example i want to recive all emails, but put only one in subscription folder. And other silently discard.... And second question is - i have many subsections to mailing lists, sieve rules looks like this: elsif header :contains "List-Id" ["cfe-dev.cs.uiuc.edu"] { fileinto "Subscriptions/Clang"; } elsif header :contains "List-Id" ["jabberd2-lists.xiaoka.com"] { fileinto "Subscriptions/Jabberd2"; } elsif header :contains "List-Id" ["chef.lists.opscode.com"] { fileinto "Subscriptions/Chef"; } elsif header :contains "List-Id" ["help-cfengine.cfengine.org"] { fileinto "Subscriptions/Cfengine"; } # rule:[Exherbo] elsif header :contains "List-Id" ["exherbo-dev.lists.exherbo.org","exherbo-commits.lists.exherbo.org"] { fileinto "Subscriptions/Exherbo"; } # rule:[Php] elsif header :contains "List-Id" ["highload-php-ru.googlegroups.com","highload-php-en.googlegroups.com"] { fileinto "Subscriptions/Php"; } # rule:[Btrfs] elsif header :contains ["List-Id"] ["linux-btrfs.vger.kernel.org"] { fileinto "Subscriptions/Btrfs"; How can i minimize this rules and save desired functionality? -- Vasiliy G Tolstov <v.tolstov(a)selfip.ru> Selfip.Ru

[Dovecot] Migrating mail from mbox to maildir using dovecot
by Donny Brooks 15 Sep '10

15 Sep '10

Hello, Currently our mail server is setup to use postfix and dovecot, which is fine except it is setup to use mbox format mail. That and procmail as we need to move to sieve but that is a different issue. I have searched until blue in the face and cannot find a 100% working solution that doesn't require alot of manual interaction to move the mail boxes from mbox to maildir. I have tried the mb2md.pl stuff but with over 150+ users that can get tedious having to log in as each one of them to migrate them. I also tried the convert plugin located here: http://wiki.dovecot.org/Plugins/Convert but it kept erroring about not able to convert the box and exiting. We have approx 200GB of mail total that needs to be migrated. Maybe I am just simply missing something but is there a way that we can migrate all the users with minimal end user interaction and minimal administration time? We need this done asap as our backups are killing us with the large mbox style files. Thanks in advance for any and all input to this. -- Donny B.

[Dovecot] Authentication with lower case username ONLY
by Leander S. 15 Sep '10

15 Sep '10

Hi, how do you guys force your users to authenticate with lower case letters ONLY? Or convert it? Is there a SASL Option to force that - or are you using scripts i.e. a bash script in combination with the command "tr" ... or a third solution I didn't think of yet? I'm using Postfix / Dovecot combination. Postfix is told to use Dovecots SASL Service to authenticate it's users. For my outgoing eMails I already wrote a script with tr which forms upercase usernames to lowercase ones ... but it's not enough. SpamAssassin is still confused and writes uppercase letters in it's Database etc. ... So that's why I'm looking for a more universal solution. P.S. I would basically prefer a convertation - but I would also be fine with a forced lower case auth system. Thanks & Regards
