[Dovecot] Rename file opened for read-write -- cannot edit subscriptions
by Jack Schmidt 31 Jan '08

31 Jan '08

Howdy, Here is a problem with fix affecting dovecot-1.0.10 (and 1.1rc13). On a linux system's CIFS mounted filesystem, it is not possible to rename a file opened read-write: $ sleep 5 >> .subscriptions.lock & mv .subscriptions.lock .subscriptions mv: cannot move `.subscriptions.lock' to `.subscriptions': Text file busy This causes problems in editing subscriptions, as the new subscription list is still open for writing before it is renamed in: lib-storage/subscription-file/subscription-file.c line 169 in dovecot version 1.0.10 (and 1.1rc13) This is an unpatched linux 2.6.21-5, CIFS mounted filesystem from a windows 2003 sp2 server. The documentation for rename(2) indicates that it is allowed to return an error when the file is already opened, so perhaps the file should be closed before the replace. Should this be done in file_dotlock_replace (before line 672) generally? Here is a patch that does so: diff -rw -U3 dovecot-1.0.10/src/lib/file-dotlock.c dovecot-1.0.10-patch/src/lib/file-dotlock.c --- dovecot-1.0.10/src/lib/file-dotlock.c 2007-12-11 13:52:08.000000000 -0500 +++ dovecot-1.0.10/src/lib/file-dotlock.c 2008-01-23 08:53:33.000000000 -0500 @@ -635,7 +635,7 @@ struct dotlock *dotlock; struct stat st, st2; const char *lock_path; - int fd; + int fd, old_errno; dotlock = *dotlock_p; *dotlock_p = NULL; @@ -669,6 +669,14 @@ } } + if (dotlock->fd != -1) { + old_errno = errno; + if (close(dotlock->fd) < 0) + i_error("close(%s) failed: %m", dotlock->path); + dotlock->fd = -1; + errno = old_errno; + } + if (rename(lock_path, dotlock->path) < 0) { i_error("rename(%s, %s) failed: %m", lock_path, dotlock->path); file_dotlock_free(dotlock);

[Dovecot] Using Dovecot with nsswitch for LDAP on Solaris
by Laurent Blume 31 Jan '08

31 Jan '08

Hello all, I'm having some issues configuring dovecot 1.0.10 on a Solaris 10 box, that uses LDAP¨for its accounts. The local accounts (in /etc/passwd) are authenticated properly and work as expected, but all accounts from the LDAP fail authentication. Those are declared for the system using PAM and NSS (/etc/pam.conf and /etc/nsswitch.conf are configured accordingly). Currently, there are WU-IMAP and Qpopper installed and working, and neither of them needed any special configuration to use the login, they're just using Unix auth. I tried various configurations, based on what I read in the wiki documentation, but nothing works, even the passwd userdb/passdb, which *should* if I understand correctly. Trying to use PAM in dovecot fails, too. Any idea what I'm doing wrong, or pointers to hints? Google returned little information about configuring Dovecot on Solaris, and none that was useful. TIA, Laurent # /opt/csw/sbin/dovecot --version 1.0.10 Sample of failure in the dovecot logs: Jan 30 18:11:00 balif dovecot: [ID 107833 local1.info] auth(default): new auth connection: pid=13210 Jan 30 18:11:09 balif dovecot: [ID 107833 local1.info] auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=127.0.0.1 rip=127.0.0.1 resp=xxxxx Jan 30 18:11:09 balif dovecot: [ID 107833 local1.info] auth-worker(default): pam(lblume,127.0.0.1): lookup service=dovecot Jan 30 18:11:10 balif dovecot: [ID 107833 local1.info] auth(default): client out: FAIL 1 user=lblume Jan 30 18:11:17 balif dovecot: [ID 107833 local1.info] imap-login: Aborted login (1 authentication attempts): user=<lblume>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured My latest config try: # /opt/csw/sbin/dovecot -n # 1.0.10: /opt/csw/etc/dovecot.conf base_dir: /var/run/dovecot/ syslog_facility: local1 protocols: imap pop3 listen(default): *:60143 listen(imap): *:60143 listen(pop3): *:60110 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot//login login_executable(default): /opt/csw/libexec/dovecot/imap-login login_executable(imap): /opt/csw/libexec/dovecot/imap-login login_executable(pop3): /opt/csw/libexec/dovecot/pop3-login mail_location: mbox:~/:INBOX=/var/mail/%u mail_executable(default): /opt/csw/libexec/dovecot/imap mail_executable(imap): /opt/csw/libexec/dovecot/imap mail_executable(pop3): /opt/csw/libexec/dovecot/pop3 mail_plugin_dir(default): /opt/csw/lib/dovecot/imap mail_plugin_dir(imap): /opt/csw/lib/dovecot/imap mail_plugin_dir(pop3): /opt/csw/lib/dovecot/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: verbose: yes debug: yes debug_passwords: yes passdb: driver: pam args: blocking=yes setcred=yes dovecot userdb: driver: passwd args: blocking=yes -- / Leader de Projet & Communauté | I'm working, but not speaking for \ G11N http://fr.opensolaris.org | Bull Services http://www.bull.com / FOSUG http://guses.org |

[Dovecot] Using dovecot proxy as multi-account aggregator?
by Mika Boström 31 Jan '08

31 Jan '08

Good day. I am trying to build a rather weird setup. The basic idea is to have a relatively simple IMAP client and let dovecot do the actual connections. So far both the documentation and my trials on this front have been rather fruitless. The desired components: - 1 dovecot server, acting as a proxy - 1 master account - 1 client connection - 0 "real" user accounts, so no local mail storage at all - N real accounts, spread over different domains - mails from different remote accounts combined to the single client connection - outgoing server for mails selected by the address of the remote account Since the proxy setup can use name(a)domain.tld as destination user, it would appear that the setup is not impossible. Hence my two questions: 1) Is it possible? 2) If yes, how in the name of all that is good and holy do I configure that? And believe me, I am fully aware that for most setups a full-featured client or fetchmail would be the easier path. Thank you for any and all help in advance, -- Mika Boström / mika.bostrom(a)nomovok.com

[Dovecot] Dovecot + Windows AD + Postfix + quota
by Maciej Paczesny 31 Jan '08

31 Jan '08

Hello, I'm almost sure that all topics and problems mentioned below were separately posted to this list already. But after spending 4 days on searching, I did'n find a compilation similar to my case. So maybe some of you guys, are able to answer to help me solve this: 1. I'd like to use userdb and passdb of Dovetcot to work with Windows AD. 2. I have to use them both because I'd like to use LDA to serve for my Postfix. 3. I DO NOT want tou use any external programs (ie PAM) to talk to AD server. 4. I was able to make my system partially running - I CAN bind to AD database, and confirm user/password. 5. I want to get follownig attributes: home directory (OK, I could put it statically), uid/gid (OK, it could be static too) and MAIL QUOTA (my users have different values - no 'statics').

[Dovecot] SQL user_query question
by John Dubchak 31 Jan '08

31 Jan '08

Hi, I am working through setting up a virtual hosting system using Dovecot, Postfix and Postgres on a CentOS 5 box running an install of the dovecot-1.0-1.2.rc15.el5 RPM. The question I have is, given this password_query SELECT clause, which all return valid values from the database: user password domain can I use a %d in the WHERE clause of my user_query? The reason I ask is that the log file shows the results coming back correctly for the password_query in the log file: dovecot: auth(default): client out: OK 1 user=user1 domain=domain.com Yet, the user_query that is logged shows: dovecot: auth(default): sql(user1,192.168.0.77): SELECT vu.virtual_mailbox AS home, vu.virtual_uid AS uid, vu.virtual_gid AS gid, vd.domain AS domain FROM virtual_users vu, virtual_mailbox_domains vd WHERE vu.domain_key = vd.id AND vu.username = 'user1' AND vd.domain = '' And the actual query in my dovecot-sql.conf looks like this: user_query = SELECT vu.virtual_mailbox AS home, vu.virtual_uid AS uid, vu.virtual_gid AS gid, vd.domain AS domain FROM virtual_users vu, virtual_mailbox_domains vd WHERE vu.domain_key = vd.id AND vu.username = '%u' AND vd.domain = '%d' I would have expected the above %d to contain the "domain" SELECT value from the password_query, but that doesn't seem to be the case. Any insight is most appreciated. Thanks, John

[Dovecot] multiple ports, different characteristics
by bill-dovecot＠carpenter.ORG 31 Jan '08

31 Jan '08

The wiki <http://wiki.dovecot.org/Iptables> leads me to believe that the only way to configure dovecot to listen for the same protocol on multiple ports is via external redirection (iptables or similar). Is that so, or can dovecot be directly configured to listen on multiple ports? Here's a concrete example of what I'm trying to accomplish. Our environment uses plaintext authentication, and so we force our users to use TLS for IMAP. For some internal connections (specifically with dovecot built-in proxying), we need non-TLS connections for IMAP. It's completely OK here if we need to listen on different ports for the two flavors of connections. Can dovecot be configured to handle this and/or do we need to run multiple instances of dovecot with different config files?

[Dovecot] Deliver a message marked as read.
by "Fábio M. Catunda" 31 Jan '08

31 Jan '08

Hi. Is there a way to deliver a message already marked as read. I would like to configure my MTA to deliver a copy of all sent messages to a folder named Sent in the user Maildir, I believe that it would be interesting to keep this folder always marked as readed. I'm not sure what define a message readed (a mark, a xheader or something) thats why I'm asking here! Any idea is apreciated. Thanks, Catunda.

hi, i've found this topic while looking for a solution for the way to use 'mail groups' with dovecot an postfix, using dovecot as LDA. i'm not sure if this patch is implemented into the source or not. or maybe there is a 'special' way to have multilpe mailboxes served by postfix/dovecot? -- Maciej Paczesny maciunio2(a)gmail.com ***Gdyby nie wymyślono elektryczności, siedziałbym przed kompem przy świeczkach***

[Dovecot] viewing a subset of folders in dumb IMAP clients
by Amitai Schlair 31 Jan '08

31 Jan '08

I have several dozen IMAP folders (stored as Maildir++). When I'm on the go with my iPhone, I only want to see a few of them. My naive solution that didn't work: 1) create an alternate login that yields my existing permissions and mail folder, but stores its own version of metadata 2) configure the iPhone to use that login 3) subscribe to the folders I want I test-drove the Dovecot config in a webmail app and it worked exactly right, but it turns out the iPhone (running the latest, 1.1.3) apparently doesn't respect IMAP subscriptions. My world-weary, clunkier, but seemingly working solution: 1) have the alternate login yield my existing permissions, but a different mail folder and metadata 2) create that mail folder, make its cur/new/tmp symlinks to the real ones, and symlink in the other folders I care about Is this safe? And is there a more elegant way to do what I want? Thanks, - Amitai

[Dovecot] Shared inbox
by adsarebad＠gmail.com 31 Jan '08

31 Jan '08

Hello all, I am using dovecot with maildir storage. I want to share a inbox of one user with another user. I read the page http://wiki.dovecot.org/SharedMailboxes but it does not deal with inboxes. I tried a test of a non-inbox folder and it worked great. The inbox does not have a .inbox folder instead its kindof spread through the root of the mailbox. Should I create a folder say .shared-inbox with a symbolic link to cur new tmp in other-guys-mail-folder? What about index files, uid list, and keywords? Thanks

When I install an SSL certificate, I can't find a config option to set configure the Server Certificate Chain file... Is this not possible or can I do it another way?

[Dovecot] More efficient Deleting of a whole folder (or Purging Trash)
by Daniel Watts 31 Jan '08

31 Jan '08

Hi, I've straced a few dovecot processes after hitting purge on a large Trash folder (35,000 messages). It looks like it is going through each message, one by one, and removing (unlinking) each one. Is there not a more efficient way to do this? If Dovecot knows the whole folder is being deleted (ie a Trash purge), could it do something clever with the filesystem to just remove the whole folder? Incidently, the command that initially deleted those 35k messages to Trash took about 1 hour to complete on my server and effectively locked my account out for all that time. There were also an awlful lot of these output from my strace: nanosleep({0, 131475000}, NULL) = 0 lstat("/home/virtual/xxx.com/home/admin/Maildir/.Folders.Porter/dovecot-uidlist.lock", {st_mode=S_IFREG|0600, st_size=0, ...}) = 0 Not sure if there's much one can do about speeding up deleting a lot of messages though. My webmail client has a 'delete all messages' button for each folder. If there was an efficient IMAP command for deleting a whole folder that would be useful in those circumstances. Interested to know if there is anything that can be improved. Thanks, Daniel Dovecot 1.0.9 XFS Filesystem Maildir Directories

[Dovecot] Convert MBOX
by Erin D. Hughes 31 Jan '08

To all, I am using dovecot --version 1.0.10 and trying to convert MBOXes to MailDir's with the end goal of creating one folder filled with users old MBOXes that when they log in for the first time will be converted to Mail Dir format. I tried this and it did not work and gave me this output; <snip> default_mail_env = maildir:%h/mail/ #convert_mail = mbox:%h/mail:INBOX=/usr/local/src/tmpmail/%u convert_mail = mbox:%h/mail/:INBOX=/usr/local/src/tmpmail/%u Jan 30 17:17:04 pop01.unix dovecot: [ID 107833 mail.info] pop3-login: Login: user=<x4500>, method=PLAIN, rip=192.168.30.192, lip=172.20.12.8 Jan 30 17:17:04 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): Loading modules from directory: /usr/local/lib/dovecot/pop3 Jan 30 17:17:04 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): Module loaded: /usr/local/lib/dovecot/pop3/lib20_convert_plugin.so Jan 30 17:17:04 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): Effective uid=3000, gid=3000 Jan 30 17:17:04 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): mbox: data=/export/x4500/mail/jp/n/e/jorgen/x4500/mail/:INBOX=/usr/local/src/tmpmail/x4500 Jan 30 17:17:04 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): mbox: root=/export/x4500/mail/jp/n/e/jorgen/x4500/mail, index=/export/x4500/mail/jp/n/e/jorgen/x4500/mail, inbox=/usr/local/src/tmpmail/x4500 Jan 30 17:17:06 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): mbox: data=/export/x4500/mail/jp/n/e/jorgen/x4500/mail/:INBOX=/usr/local/src/tmpmail/x4500 Jan 30 17:17:06 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): mbox: root=/export/x4500/mail/jp/n/e/jorgen/x4500/mail, index=/export/x4500/mail/jp/n/e/jorgen/x4500/mail, inbox=/usr/local/src/tmpmail/x4500 Jan 30 17:17:06 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): maildir: data=/export/x4500/mail/jp/n/e/jorgen/x4500/mail/ Jan 30 17:17:06 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): maildir: root=/export/x4500/mail/jp/n/e/jorgen/x4500/mail, index=/export/x4500/mail/jp/n/e/jorgen/x4500/mail, control=, inbox= Jan 30 17:17:07 pop01.unix dovecot: [ID 107833 mail.error] POP3(x4500): Mailbox conversion: Couldn't copy mailbox dovecot.index.log: BUG: Unknown internal error Jan 30 17:17:07 pop01.unix dovecot: [ID 107833 mail.error] POP3(x4500): Mailbox conversion: Couldn't copy mailbox dovecot.index: BUG: Unknown internal error Jan 30 17:17:08 pop01.unix dovecot: [ID 107833 mail.error] POP3(x4500): Mailbox conversion: Couldn't copy mailbox dovecot.index.cache: BUG: Unknown internal error Jan 30 17:17:11 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): maildir: data=/export/x4500/mail/jp/n/e/jorgen/x4500/mail/ Jan 30 17:17:11 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): maildir: root=/export/x4500/mail/jp/n/e/jorgen/x4500/mail, index=/export/x4500/mail/jp/n/e/jorgen/x4500/mail, control=, inbox= </snip> This actually created the x4500-convert directory but did not populate it Then I tried this trying to get the mail dir created and populated. <snip> #convert_mail = mbox:%h/mail:INBOX=/usr/local/src/tmpmail/%u convert_mail = mbox:/usr/local/src/tmpmail/%u:INBOX=/var/mail/%u Jan 30 17:22:45 pop01.unix dovecot: [ID 673593 mail.info] Dovecot v1.0.10 starting up Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.info] pop3-login: Login: user=<x4500>, method=PLAIN, rip=192.168.30.192, lip=172.20.12.8 Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): Loading modules from directory: /usr/local/lib/dovecot/pop3 Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): Module loaded: /usr/local/lib/dovecot/pop3/lib20_convert_plugin.so Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): Effective uid=3000, gid=3000 Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): mbox: data=/usr/local/src/tmpmail/x4500:INBOX=/var/mail/x4500 Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): mbox: root=/usr/local/src/tmpmail/x4500, index=/usr/local/src/tmpmail/x4500, inbox=/var/mail/x4500 Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): mbox: data=/usr/local/src/tmpmail/x4500:INBOX=/var/mail/x4500 Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): mbox: root=/usr/local/src/tmpmail/x4500, index=/usr/local/src/tmpmail/x4500, inbox=/var/mail/x4500 Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): maildir: data=/export/x4500/mail/jp/n/e/jorgen/x4500/mail/ Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): maildir: root=/export/x4500/mail/jp/n/e/jorgen/x4500/mail, index=/export/x4500/mail/jp/n/e/jorgen/x4500/mail, control=, inbox= Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.error] POP3(x4500): mkdir_parents(/usr/local/src/tmpmail/x4500/.imap/INBOX) failed: Not a directory Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.error] POP3(x4500): open() failed with subscription file /usr/local/src/tmpmail/x4500/.subscriptions: Not a directory Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.error] POP3(x4500): Sending log messages too fast, throttling..

Can some one please help w/this? Additionally is there a way to run mail_convert on the command line to try to sort out the arguments? I noticed the converts are .so and .a in /usr/local/lib/dovecot/ so I doubt it but it can not hurt to ask.

I've re-sent the message, this time to the list. It should arrive along with this.

[Dovecot] Virtual Alias Forwarding
by Eric Biondi 30 Jan '08

30 Jan '08

I'm having a problem with Dovecot and forwarding of aliases. Any help would be greatly appreciated. I'm using Postfix, Mysql, dovecot, amavis. mysql> SELECT * FROM alias; | address | goto | domain | created | modified | active | It seems from the logs that incoming mail is being delivered to the mailbox via dovecot. Mail gets to the correct mailbox (address field), however, if I change the destination mailbox (goto) in the alias table in mysql, the mail still goes to the main mailbox (address). mysql_virtual_alias_maps.cf looks to be configured correctly but I'm suspecting that dovecot is circumventing that file. I'll post maillog entry, dovecot-deliver.log entry, dovecot-mysql.conf, mysql_virtual_alias_maps.cf, and dovecot.conf below in case that helps. Thanks in advance for anything that helps me resolve this.

[Dovecot] sa learning from an imap spam folder
by Zbigniew Szalbot 29 Jan '08

29 Jan '08

Hello, I am sorry if I am writing to a wrong list because honestly I do not know where to write but I would like to be able to set up sa-learn via cron to learn from spam folder of a particular email account (via IMAP). Can anyone share how to do it? Is dovecot involved in it? I am using: Exim 4.69 Dovecot 1.0.10 p5-Mail-SpamAssassin-3.2.1 Thanks a lot for helping. Zbigniew Szalbot

[Dovecot] Load average on machine 400+
by Patrick 29 Jan '08

29 Jan '08

Hi all, Over the past week our mail server which NFS mounts the /home directory for mail has been experiencing major load issues. When doing a 'top', it appeared that slapd was the culprit (we use LDAP for authentication), but after upgrading the system and updating ldap, the cpu usage for LDAP has gone down, but the load average as not. I'm using Maildir. Everything from /home is NFS mounted, and the structure looks like this: /home/USERNAME/Maildir We're doing about 300 email messages a minute right now to that server, which isn't that much. I'm at a loss of words right now as I do not know where to troubleshoot from here. I've come up with the following questions: 1) I've noticed that some of our users have 500mb Maildir folders some even have 3gb+ - would this cause the CPU to have such a high load? 2) Currently on the box there is about 120 POP3 connections and 40 IMAP connections. Could this be the issue? 3) When I first set up this server, I appended INDEX=MEMORY to the end of the mail_location line. Should I remove this? I wanted to either remove it or put it on the local machine to speed things up. Here is my config: ##################### protocols = imap imaps pop3 pop3s listen = * disable_plaintext_auth = no log_path = /var/log/dovecot.log ssl_disable = no ssl_cert_file = /usr/share/ssl/xyz.com/xyz.com.crt ssl_key_file = /usr/share/ssl/xyz.com/xyz.com.key login_dir = /var/run/dovecot-login login_user = dovecot login_process_size = 64 login_process_per_connection = yes login_max_processes_count = 128 login_max_connections = 256 mail_location = maildir:/home/%u/Maildir:INDEX=MEMORY mmap_disable = yes fsync_disable = yes first_valid_uid = 200 maildir_copy_with_hardlinks = yes maildir_copy_preserve_filename = yes protocol imap { imap_client_workarounds = outlook-idle delay-newmail } protocol pop3 { pop3_no_flag_updates = no pop3_lock_session = no pop3_uidl_format = %08Xu%08Xv pop3_client_workarounds = } protocol lda { fsync_disable = no postmaster_address = postmaster(a)xyz.com hostname = mail.xyz.com } auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ auth_username_format = %Lu auth_verbose = yes auth_worker_max_count = 30 auth default { mechanisms = plain login passdb pam { args = blocking=yes } userdb passwd { } user = dovecot-auth socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } dict { } plugin { } ##################### Again, this only happened within the past 1-2 weeks. How can I fix? Thanks in advance! Patrick

Thanks to Marius, I've got this problem fixed! I don't know how or why, but selinux directory contexts have been altered during the update for everyone else on the system except myself (what makes it odd is that my user has the same group and permissions as everyone else). So what did the trick was to apply: chcon -t user_home_dir_t to each user's home, mail, .imap and INBOX directories. Thanks again for pointing me in the right direction, Marius!

[Dovecot] Messages not moved from Inbox by Apple Mail (Dovecot 1.0.10)
by Tom Collins 29 Jan '08

29 Jan '08

I just upgraded a server from Courier-IMAP to Dovecot, and I'm seeing some odd behavior. It's probably the result of something I did wrong in my configuration, and I'm hoping someone will let me know the easy fix for it. I have rules set up in Apple Mail to move and copy messages to different folders, some of which are IMAP folders, others on my own system. With Courier-IMAP, the messages would get moved without a problem. With dovecot, that's not happening. Here's my dovecot config. I've tried changing maildir_copy_with_hardlinks and maildir_copy_preserve_filename to "no", but that didn't seem to help. # 1.0.10: /usr/local/etc/dovecot.conf disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login verbose_proctitle: yes first_valid_uid: 89 last_valid_uid: 89 first_valid_gid: 89 last_valid_gid: 89 maildir_copy_with_hardlinks: yes maildir_copy_preserve_filename: yes namespace: type: private prefix: INBOX. inbox: yes auth default: mechanisms: plain login digest-md5 cram-md5 username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@% username_translation: %@ passdb: driver: vpopmail userdb: driver: vpopmail plugin: quota: maildir I haven't tried logging the IMAP session yet, but I can turn off SSL, fire up Wireshark and monitor the session if necessary. Is this a known problem? I'm able to move messages between folders manually, but when Apple Mail moves the new messages it doesn't work. -- Tom Collins - tom(a)tomlogic.com Vpopmail - virtual domains for qmail: http://vpopmail.sf.net/ QmailAdmin - web interface for Vpopmail: http://qmailadmin.sf.net/

[Dovecot] Dovecot/SeLinux issues after RHEL5.1 upgrade
by Ion Soltan 28 Jan '08

28 Jan '08

Hello to everyone on the list, I have upgraded my RHEL4 to RHEL5.1 yesterday (all updates have been applied to it as well). I used to have dovecot v0.99.11 on the old system. Everything was working fine. Now I have 5.1 and its respective dovecot v1.0.rc15. Upon upgrading to RHEL5.1, dovecot no longer works correctly. The first thing I did after rewriting the config file for the updated version, was to check my own email. It works fine. However, no other user on the system can check his/hers. Here is what the log shows for everyone except myself: ============================ Jan 27 13:56:41 warp dovecot: POP3(jj): open() failed with file /home/jj/mail/.imap/INBOX/dovecot.index.log: Permission denied Jan 27 13:56:41 warp dovecot: POP3(jj): open() failed with file /home/jj/mail/.imap/INBOX/dovecot.index.log: Permission denied Jan 27 13:56:41 warp dovecot: POP3(jj): Couldn't open INBOX: Internal error occurred. Refer to server log for more information. [2008-01-27 13:56:41] ============================ There are NO complaints reported by selinux in the logs. If I setenforce 0 (disable selinux), everything is working fine for everyone. If I disable selinux monitoring on dovecot (setsebool dovecot_disable_trans 1), nothing changes, which makes me think that something else is causing the problem. I do very much want to use selinux, however, I cannot figure out what the problem is and I have been trying for many hours. Can anyone help? Thanks, Ion

[Dovecot] Howto set mail_location for system users over LDAP?
by Patrick Ben Koetter 28 Jan '08

28 Jan '08

In parallel to /etc/passwd I do have my system users in LDAP. I want to store their messages in /srv/mail/state-of-mind/<username>. Dovecot has been configured to retrieve the extra field mail to override the mail_location setting. I can see in the log it retrieves the correct information as long as I run Dovecot deliver as Postfix service 'dovecot' as shown in section "Virtual users" <http://wiki.dovecot.org/LDA/Postfix>. However if I use deliver as specified for "System users" it ignores the LDAP settings and delivers messages to my users $HOME directory as specified in /etc/passwd. Is this correct behaviour? What do I need to do to use the Postfix $mailbox_command _and_ have Dovecot deliver honor my LDAP settings?

[Dovecot] Thunderbird Problem - What causes this?
by Marc Perkel 28 Jan '08

28 Jan '08

Strange problem and I'm not sure what's causing it. I'm using IMAP. A new message arives in the inbox. I see it displayed in the message list in bold. I click on the message and it looks like it's reading it by the previous message that was in the window remains and the new message is still bold (unread). However I can then click on an old message and then click on the new message again and it reads. I have also seen Thunderbird be in a somewhat unresponsive state. You can click on messages and they don't read. But Shutting down Thunderbird and restarting it make it responsive again. Has anyone seen this?

[Dovecot] proxy configuration
by bill-dovecot＠carpenter.ORG 27 Jan '08

27 Jan '08

Before I spend some time experimenting with what might be impossible, maybe someone can just tell me (either "how" or that it's impossible). I'd like to get perdition out of my environment (mainly to have one less moving part in my architecture). I'm looking at dovecot's built-in proxying. In my setup, I don't have dedicated front-end machines. A user can connect to any server, but their mail files live on one particular machine. I'd like to transparently proxy them from whatever machine they happen to hit to their home machine. Except for the "proxy_maybe" feature advertised for dovecot 1.1, I don't see a surefire way to do this. Has anyone done it, or can anyone say for sure that it can't reasonably be done until "proxy_maybe"?

[Dovecot] Thunderbird trouble with Dovecote and dbox
by Hannes Dorbath 27 Jan '08

27 Jan '08

Hi, I'm new to Dovecot -- migrating from Cyrus. Version and config: # 1.1.beta14: /etc/dovecot/dovecot.conf protocols: imaps login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_location: dbox:/data/mail/%u auth default: passdb: driver: pam args: * userdb: driver: passwd Linux 2.6.22-gentoo-r10 x86_64 GNU/Linux I have chosen dbox as mailbox format as it is claimed to be the best performing -- and performance is the reason I'd like to migrate away form Cyrus. I'm aware that dbox might not be 100% mature, but I'm good at doing backups. Anyway, so far I have the following problems: - Greyed out Inbox After creating a new user and connecting to that account with Thunderbird the first time, the INBOX folder is greyed out and in italic. Restarting Thunderbird 3-4 times seems to fix the problem. Google suggests that other people have seen the same, but they never found a solution. - After creating sub folders they are not displayed, I need to manually subscribe to them after creation. - When "Trash" contains folders, Thunderbird is unable to "Empty Trash". While the folder is removed from Thunderbird's folder tree, it's there again after a restart of Thunderbird. - Deleted folders are never deleted from the file system. I'm not sure if this is intended with dbox. - Moving folders via drag & drop does not work, it just does nothing. So basically nothing besides reading existing mails seems to work reliable. My basic questions now is, are those problems related to dbox, or to Dovecot and Thunderbird in general? -- Best regards, Hannes Dorbath

[Dovecot] User-specific mail_location using passwd database
by Maxime Brugidou 26 Jan '08

26 Jan '08

current version : 1.0.rc15 Hi, I would just like to know if it's possible to have different mail locations for different UNIX users, using pam authentication and the passwd userdb. We also have some virtual users using an SQL db. The current config is : auth default: username_translation: %@ verbose: yes debug: yes passdb: driver: pam passdb: driver: passwd passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf Then we can only modify mail locations for virtual users on the sql userdb. But how could we change it for real users ? Thanks for help, -- Maxime Brugidou

[Dovecot] Dovecot LDA (deliver) stopped working
by falz 26 Jan '08

26 Jan '08

Hello, One day a week or so ago, a server that's Postifx w/ Local users, dovecot w/ LDA decided to stop working. The only thing that stopped is the LDA portion, the rest all works fine. I also posted to the postfix mailing list yesterday but wasn't able to debug any further. Here's the situation: if I use mailbox_command to point to deliver, postfix will always put the message in the deferred queue. However, if I run deliver from the command line, it works fine. I've recompiled Dovecot and Postfix cleanly and reinstalled a few times to ensure permissions are OK. It's not a virtual setup, so I do NOT have setuid root on the deliver binary. Postfix people suggested placing a wrapper script for mailbox_command, which I did, and have it log to a text file, so I do know that deliver is being called. However, although I have LDA debug logging on, and it DID log prior to this, when postfix supposedly calls deliver, dovecot does NOT log anything. It DOES however log if I call deliver from any account (root or not) from the command line (ls / | /path/to/deliver -d localaccountname). Any way I can debug this further? I would assume that deliver would log something even if it's called, but it appears that it does not. My postfix related details are here: http://marc.info/?l=postfix-users&m=120119147917409&w=2 I followed the postfix/lda wiki (http://wiki.dovecot.org/LDA/Postfix) when setting it up, and it worked perfectly for months. I did indeed only have to change mailbox_command and it worked (I'm also using sasl auth, but that should be unrelated). Obviously something happened on my system, but I would assume recompiling/reinstalling would reset things. Nothing in the config files for postfix or dovecot changed, from what I can see, as generally I am the only one making changes. Thanks, --falz

[Dovecot] Count breaks socket
by Marc Perkel 26 Jan '08

26 Jan '08

If I use the socket option I can't use the count option to create more authentication processes. I get this error.

[Dovecot] Capturing credentials for imap sync
by Master Abi 26 Jan '08

26 Jan '08

Hi List All the imap sync apps I could find requires the username /password credentails to be known before a sync occurs. I have Dovecot using ldap acting as a nearline backup mail server to MS Exchange. Every hour imapsync syncs mail between Exchange and Dovecot. This all works fine becuase the users credentials are known, but when new users are added I would like the process to work seemless like this: The user is added to the Active Directory. The mail client is configured with 2 accounts with identical credentials, one of which is connected to Dovecot. When the new client connects to dovecot, the credentials are captured and stored so that imapsync can use it. This If there is another way this can be done with dovecot, could I please be enlighten. I have read the doco on migration but I am not quite migrating but more replicating. Thank you

[Dovecot] symbolic links to root node
by Martin Preen 25 Jan '08

25 Jan '08

Hello, I have a question about the way Dovecot limits file system access. Currently we're using Dovecot 1.0.5 (Solaris 10). In some cases users have a symbolic link like "z: -> /" in their mail directory. As a result there are log entries like Jan 25 13:30:31 imap1 dovecot: [ID 107833 mail.error] IMAP(xyz): stat(/home/xyz/.wine/dosdevices/c:/windows/profiles/xyz/.../z:/proc/28381/root/proc/28381/.../root/proc/28381/Player/#SharedObje Jan 25 13:30:31 imap1 dovecot: [ID 107833 mail.error] IMAP(xyz): x) failed: File name too long We know the reason (the links are create by Wine) but unfortunately we cannot get rid of them. Is there something I can do (these links should be ignored) ? Or is it a bug ? Greetings.

[Dovecot] New server error
by Anne Wilson 25 Jan '08

25 Jan '08

I'm setting up a replacement mail server on a CentOS 5.1 box. The dovecot version is 1.0.rc15. 'dovecot -n' returns # /etc/dovecot.conf login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: passdb: driver: pam userdb: driver: passwd I can telnet localhost 143 and log in. I have given kmail the address of the server and an Inbox has been created, but no option to create sub-folders. If I attempt to send a message kmail freezes. Clearly something's wrong. I am using configuration files from the old server, modified only to the new server details. I have alias and transport hashes. What else should I be looking at? Thanks Anne

[Dovecot] dovecot + antispam + sendmail
by Anil 25 Jan '08

25 Jan '08

Whats a good antispam solution? I am using sendmail and dovecot 1.1. I came across dovecot's antispam plugin, but it seems it does not support 1.1 yet. I am also looking for something non-perl based. I am already doing some greylisting with sendmail milter. Any other good suggestions? If not, I guess I might have to downgrade back to 1.0 dovecot. Thanks

[Dovecot] Is there a way to limit multiple POP3 connections?
by patrickm 25 Jan '08

25 Jan '08

Hi all, Please correct me if I'm going about this the wrong way. We currently have a 3 system Mail server set up - two machines are the load balanced frontends running Dovecot and Postfix, and the third machine is our NFS. Over the past 4 months or so, I've tweaked and optimized our mail servers, and we receive roughly 3 million emails a day combined through this setup. Sometimes, the IO Wait is horrible on the load balanced servers - it can get up into the 80-90% range sometimes - it's usually when a lot of email is being passed, or there are a lot of POP3 and IMAP connections. One item which I believe to be hurting I/O performance is the fact I used a RAID 10 setup using SATA II drives on an LSI Logic SATA I controller, in 32 bit mode. Until we rebuild our mail setup (which may be another year down the road), I want to make sure these servers are optimized to the fullest just in case we get heavy I/O usage, it doesn't slow down if at all possible. One thing I noticed is that when issuing a 'ps aux | grep -i pop' or 'ps aux | grep -i imap' I see the same username 2,3,4,5 times, sometimes more. When issuing a 'tail -f /var/log/dovecot.log' I notice that some users log into POP3 every 3 seconds, sometimes sooner. Without upsetting the customer, is there anything I can do on my end to disallow people logging into POP3 multiple times at once? Any tips on this is very much appreciated. Thanks in advance. Patrick

[Dovecot] sieve vacation
by Asbjørn Sannes 25 Jan '08

25 Jan '08

I think sieve vacation is cutting off the last line of the vacation message, is this a known problem? vacation addresses: "john(a)example.com" "not here now" Would return an empty message, changing it to: vacation addresses: "john(a)example.com" "not here now have a nice day" And it would send a message with only "not here now" in it, but not "have a nice day". For the record using: http://dovecot.org/releases/sieve/dovecot-sieve-1.0.2.tar.gz Mvh, Asbjørn Sannes

[Dovecot] Dovecot + MySQL problem
by Timo Neuvonen 25 Jan '08

25 Jan '08

I recently upgraded my Fedora Core 6 (mail)server to Fedora 8. Unfortunately I don't any more have absolutely reliable information available on the Dovecot version that was the last one I had on FC6, but I guess it has been 1.0.3 (I found it from a FC6 repo right now). Currently, Fedora 8 has version 1.0.7 that comes as binary rpm from Fedora repos. So, the problem: I had set up an authentication system using mysql database. It worked fine as long as I were using FC6, but after upgrade Dovecot dies immediatedly after the system startup, writing this to log: Jan 24 16:14:46 test dovecot: Dovecot v1.0.7 starting up Jan 24 16:14:46 test dovecot: auth(default): Unknown database driver 'mysql' Jan 24 16:14:46 test dovecot: Auth process died too early - shutting down My first idea was that Dovecot is compiled without sql support. However: [root@test etc]# dovecot --build-options Build options: ioloop=poll notify=inotify ipv6 openssl SQL drivers: mysql postgresql sqlite Passdb: checkpassword ldap pam passwd passwd-file shadow sql Userdb: checkpassword ldap passwd prefetch passwd-file sql static If I change "mysql" to "pgsql" in the following in the conf file, the error message will change accordingly: # Database driver: mysql, pgsql, sqlite #driver = driver = mysql I also have CentOS 5.1 system with Dovecot 1.0.rc15. I tried the database authentication with similar conf there, it did work. So, is there an essential (intentional) change in sql configuration between 1.0.rc15 (and obviously 1.0.3) to 1.0.7, or should I start finding the problem from incorrectly built binary of 1.0.7? Regards, Timo

[Dovecot] Maildir format, "From " in the first line
by Sébastien Munch 24 Jan '08

24 Jan '08

Hello, Using Dovecot's deliver MDA, all mails are stored with the line "From <sender> <date>" appended. When forwarding these mails as attachements, the recipients get the source code. When Postfix delivers emails directly in the Maildirs, this first line is not appended, and there is no problem when forwarding the mails. Why is this line appended by deliver ? Is there a way to remove it ? Or is there something else I can do to avoid this forwarding problem. I'm using Dovecot 1.0.rc15 from Debian Etch.

You could verify that this happens. So I can't really say anything else than that the problem is somewhere outside Dovecot..
