[Dovecot] auth: Error: PLAIN(user): Request 27511.1 timeouted after 150 secs, state=3

Since upgrading from Dovecot 2.0.beta4 + patches http://hg.dovecot.org/dovecot-2.0/rev/96496e1d3d12 and http://hg.dovecot.org/dovecot-2.0/rev/aefa279e2c70 to Dovecot 2.0.beta 5, I have started to see the subject error from Dovecot for SASL authentications. It doesn't happen every time, but it happens more often than not. It doesn't seem to affect Postfix's acceptance of the message. One other change made about the same time as the dovecot upgrade that may be involved is the addition of smtpd_sasl_authenticated_header = yes in Postfix. Here is a sequence of relevant log messages for one incoming message.

Manao ahoana, Hello, Bonjour, We currently run courier POP . We would like to switch to Dovecot. I encounter problems when migrating the UIDL because we have big Maildirs and POP re-downlading the data is not possible for most of the users. I tried the http://www.dovecot.org/tools/courier-dovecot-migrate.pl script but I still have the re-downloading event. What are your stories and advices about courier-to-dovecot move?

[Dovecot] Help with acl_shared_dict
by Marcio Merlone 11 May '10

11 May '10

Hi all, I am trying to set up shared folders with dovecot 1.2.10-0xk1 on a ubuntu 8.04 server and so far so good. I managed to share a folder using GOSa GUI, but I cannot list it on Thunderbird yet, because of acl_shared_dict param (I guess). I tried BDB as per the wiki: plugin { acl_shared_dict = file:/var/lib/dovecot/shared-mailboxes.db } I gave shared-mailboxes.db 0666 perms but it keeps resetting permissions to 0600, which gives me "open(/var/lib/dovecot/shared-mailboxes.db) failed: Permission denied" errors. So I went to try sql dict, but could not find where to put sql server connection details like user, host, password. dovecot -n (with sql dict): # 1.2.10: /etc/dovecot/dovecot.conf # OS: Linux 2.6.24-27-server i686 Ubuntu 8.04.4 LTS log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps managesieve ssl_cert_file: /etc/ssl/certs/dovecot.pem ssl_key_file: /etc/ssl/private/dovecot.pem disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login mail_privileged_group: mail mail_location: maildir:~/Maildir mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): quota imap_quota acl imap_acl mail_plugins(imap): quota imap_quota acl imap_acl mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: shared separator: / prefix: shared/%%u/ location: maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u list: children lda: postmaster_address: postmaster(a)a1.ind.br hostname: a1.ind.br mail_plugins: quota sieve acl auth default: mechanisms: plain login passdb: driver: pam args: session=yes blocking=yes dovecot userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/dovecot mode: 436 user: postfix group: postfix plugin: quota: maildir:storage=10485760 acl: vfile acl_anyone: allow acl_shared_dict: proxy::acl dict: acl: mysql:/etc/dovecot-dict-sql.conf (/etc/dovecot-dict-sql.conf is a copy from the wiki) Have I missed something?

[Dovecot] Best location for indexes?
by Brandon Lamb 11 May '10

11 May '10

I cant seem to find anything via a google search, so if this has been answered I apologize. I am wondering if INDEX=MEMORY is going to give the best performance versus files? I have a server with directly attached storage, 8 gigs of ram, about 500 gigs of data. I am ok with losing and having to rebuild the indexes on a reboot as the last uptime was over 200 days

Hello, Last Saturday i scp the vmail folder from server1 running SLES to server2 running Debian.

[Dovecot] Reading emails, vmail user mail access problems.
by David Haggard 11 May '10

11 May '10

Hello, I have a new installation of Ubuntu 10.04 64bit and all packages are from the Ubuntu repos. dovecot version 1.2.9 My goal is to have a basic email server setup with imap and pop support so imap users can send and receive email for the company. Setup: I have a few users that will be using this mail server so I do not need anything advanced and I am ok with creating a user account with a password and managing email addresses manually. I currently have system accounts for a test user and I have setup virtual mailbox as this mail server will host 2+ domains. Postfix is installed and running, I also confirmed mail flow to this box and from this box is working to the test user created. I can log in with the test username of the system and this is the point at which I have some issues as I am having a permission problem which I think is related to dovecot. What I am not able to do is download emails via imap client, but I can send emails just fine. If I change the permissions of the virtual mailbox to the test user that is logged in to chmod 777 I can download emails, but I can't do this for each new email to that users mailbox. /var/vmail/DOMAIN/USER1/cur/ and anything listed here will be owned by vmail so no other user can read it. (can't download emails) as dovecot seems to be trying to use USER1 as a user to read the files. How can I have dovecot read emails as vmail no matter what user logs in? I have tried many config changes using vmail but its failed so I need some advise. Here is my config: I edited the DOMAIN to hide the real domain used. # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-21-server x86_64 Ubuntu 10.04 LTS ext4 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_location: maildir:/var/vmail/DOMAIN/%n/ mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 auth default: passdb: driver: pam userdb: driver: passwd userdb: driver: static args: uid=vmail gid=vmail home=/var/vmail/DOMAIN/%n/ Thank you

[Dovecot] wrong config file?
by Phil Howard 10 May '10

10 May '10

The sample provided config file (the one I started with by editing it) included the following text: # ------------------------------ WARNING ------------------------------- > > # If there's a file /etc/dovecot/dovecot-postfix.conf, which is part of > # dovecot-postfix package, it will be used instead of dovecot.conf. > > # Keep in mind that, if that file exist, none of the changes in > # /etc/dovecot/dovecot.conf will have effect on dovecot's configuration. > # In that case you should customize /etc/dovecot/dovecot-postfix.conf. > > # ------------------------------ WARNING ------------------------------- > So I expected it would use that by default. It seems to not be doing so. Does this mean I have to modify the startup scripts to add the -c option to force the use of this config file? Or should I just put all my configs in the default "/etc/dovecot/dovecot.conf" file? When doing "dovecot -n" it became apparent that my configs were not being used. But "dovecot -c /etc/dovecot/dovecot-postfix.conf -n" was doing it. Any idea why it's not behaving as those comments described?

[Dovecot] configuration user= or auth_user=
by Phil Howard 10 May '10

10 May '10

The sample config file has: # User to use for the process. This user needs access to only user and # password databases, nothing else. Only shadow and pam authentication # requires roots, so use something else if possible. Note that passwd # authentication with BSDs internally accesses shadow files, which also # requires roots. Note that this user is NOT used to access mails. # That user is specified by userdb above. user = root # Directory where to chroot the process. Most authentication backends don't # work if this is set, and there's no point chrooting if auth_user is root. # Note that valid_chroot_dirs isn't needed to use this setting. #chroot = So is the variable for the authentication process user supposed to be "user" or "auth_user"? It would make more sense to be "auth_user". Is it just "user" for legacy reasons, and the reference to "auth_user" is in error? Or can either name be used? Also, those of you who change this, do you change it to something existing like "dovecot" or "vmail" or "nobody" or do you make a whole new user for it?

[Dovecot] lmtp_generic_maps with postfix
by derwyn 10 May '10

10 May '10

Hi All, I am new to dovecot so this may be a very easy thing to do. I need to setup a postfix+dovecot server for a multilocation setup The rules are very simple mails to *(a)local.example.com send to dovecot mails to *(a)otherlocation.example.com send to smtp:[otherlocation] But the users are created on dovecot as user(a)example.com. How can I configure dovecot to accept mails for *(a)local.example.com and deliver to *(a)example.com I use lmtp_generic_maps for a similar thing in postfix+cyrus Thanks Derwyn.

[Dovecot] problems implementing dovecot LDA with Postfix
by Stan Hoeppner 09 May '10

09 May '10

Per the instructions here http://wiki.dovecot.org/LDA and here http://wiki.dovecot.org/LDA/Postfix I set postmaster_address = postmaster(a)hardwarefreak.com in /etc/dovecot/dovecot.conf and mailbox_command = /usr/lib/dovecot/deliver in /etc/postfix/main.cf When I restart dovecot I get this: [07:17:00][root@greer]/etc/dovecot$ /etc/init.d/dovecot restart Restarting IMAP/POP3 mail server: dovecotError: Error in configuration file /etc/dovecot/dovecot.conf line 754: Unknown setting: postmaster_address Fatal: Invalid configuration in /etc/dovecot/dovecot.conf failed! And after restarting Postfix and sending a test message from a gmail account I get this in the mail log: May 9 07:26:09 greer postfix/qmgr[13384]: AEE976C32C: from=<snugmonster(a)gmail.com>, size=1628, nrcpt=1 (queue active) May 9 07:26:09 greer dovecot: deliver(stan): Fatal: postmaster_address setting not given May 9 07:26:09 greer postfix/local[13392]: AEE976C32C: to=<stan(a)hardwarefreak.com>, relay=local, delay=1.4, delays=1.3/0.03/0/0.04, dsn=4.3.0, status=deferred (temporary failure) The server is Debian Lenny 5.0.4 with Postfix 2.5.5 and Dovecot 1.2.11 from Lenny backports. Any ideas? Everything I've found via Google relating to this Dovecot startup error has to do with people converting old dovecot.conf files to a new dovecot version. -- Stan

[Dovecot] CRYPT scheme and 8 character limit
by Phil Howard 09 May '10

09 May '10

I've decided that having users supply cleartext passwords for me to encrypt and encode is a bad idea, anyway. So maybe I won't need dovecotpw. The idea is that users supply an already-encrypted password. Most of the users can fetch their login password from /etc/shadow on their own computer. Wiki page http://wiki.dovecot.org/Authentication/PasswordSchemes indicates that scheme name CRYPT is the one that uses the libc crypt() function. But it also says it uses no more than 8 characters. Then there is MD5-CRYPT. But that doesn't call crypt(), I presume. No limit on password size is indicated. But this at least looks like SOME of the encrypted passwords I have. Other passwords I have have ids indicating SHA-256 and SHA-512. Here is an example from /etc/shadow that encrypted the clear password "dovecotandpostfix" (in case it is necessary to test it): $6$IwZzpjjj$p1VrkxQmgmTED8iQnQrV3sVEZpBmw2N8oD1ykOguXB5tf8aahICesX0TF6.VMThIW2QFs1buHjT3eDtnaAFhF1 The big question is, what scheme name should I use for these passwords? I can, of course, consider the id (6 in the above example, suggesting SHA-512) if there is one (so far all are like this). But the other consideration is most of the passwords are longer than 8, some longer than 12, characters. So apparently CRYPT can't be used in those cases (so I can't have the automatic identification of crypt() to detect the scheme). What scheme would I use for the various passwords? What scheme would be used for the above example for starters? What if the id is 5 or 1 (the ones documented for the crypt() call)?

[Dovecot] looking for feedbacks on courier to dovecot
by Mihamina Rakotomandimby 08 May '10

08 May '10

Manao ahoana, Hello, Bonjour, We currently run courier POP . We would like to switch to Dovecot. I encounter problems when migrating the UIDL because we have big Maildirs and POP re-downlading the data is not possible for most of the users. I tried the http://www.dovecot.org/tools/courier-dovecot-migrate.pl script but I still have the re-downloading event. What are your stories and advices about courier-to-dovecot move? Misaotra, Thanks, Merci. -- Architecte Informatique chez Blueline/Gulfsat: Administration Systeme, Recherche & Developpement +261 34 29 155 34 / +261 33 11 207 36

[Dovecot] Questions, Issues with 2.0
by Kelsey Cummings 08 May '10

08 May '10

I'm trying to use an external program to set the location of user's maildirs to match an existing hashing schema but the docs for how to do this in 1.x do not seem to apply to 2.0 or I'm misinterpreting them. protocol imap { mail_executable = /opt/dovecot-test/sonic-imap ... This correctly executes the and attempts to sets the MAIL variable but it appears that mail_executable is run before the user is logged in so the $USER variable isn't set and the process' uid is still 0. We also need to have dovecot include an additional maildir for each user that is currently stored outside of the user's main maildir directory into the same namespace as a specific folder name. Is there a way to do this in dovecot directly or will it need to be hacked (as it is currently with courier) or could it be done with a plugin? I've also noticed that while doveconf complains about mail_executable: May 3 13:44:10 a dovecot: config: Obsolete setting in /opt/dovecot-test/etc/dovecot/conf.d/imap.conf:7: mail_executable has been replaced by service { executable } However, when replaced as suggested by doveconf: protocol_imap { executable = /opt/dovecot-test/sonic-imap ... It fails altogether: doveconf: Fatal: Error in configuration file /opt/dovecot-test/etc/dovecot/conf.d/imap.conf line 7: Unknown setting: executable Similarly, it also suggests 'drop_priv_before_exec = no' which doesn't appear to be valid either. -- Kelsey Cummings - kgc(a)corp.sonic.net sonic.net, inc.

[Dovecot] Dovecot version mismatch - after restart

Getting the followng error when managesieve is enabled. Any other post I've read says this problem is because the service hasn't restarted after upgrade.

[Dovecot] Requiring STARTTLS only on some networks
by Thomas Hummel 07 May '10

07 May '10

Hello Timo, is there a way, either in 1.2.x or in 2.x to activate disable_plaintext_auth=yes only for some address or network ? The idea would be to enable clients from the internal networks to keep making clear text connections while forbidding it to the rest of the world.

[Dovecot] Tracing sieve execution
by Jerry 07 May '10

07 May '10

I have just recently begun learning how to use sieve. For the most part, it works fine. The problem is that I have created some rather complicated rules. Occasionally, an e-mail will get sorted incorrectly and I am not able to easily determine what rule caused it to occur. Is there any way or utility that I could use to actually see what rule or line in the sieve file caused the action? -- Jerry Dovecot.user(a)seibercom.net Disclaimer: off-list followups get on-list replies or get ignored.

[Dovecot] dovecotpw documentation
by Phil Howard 07 May '10

07 May '10

Where can I find documentation on how to use the "dovecotpw" program that I was referred to? No man page. No wiki. Very little from "dovecotpw -h". What I need to do is generate the "passwd-file" contents with an MD5 scheme (the one equivalent to /etc/shadow is preferred).

[Dovecot] ACLs and public folders
by hyperbatus＠gmx.de 07 May '10

07 May '10

Dear list, I am using dovecot 1.0.15 on Debian Lenny. I have a public folder, I use ACL / vfile (without public ACL), and I use maildir / vmail. Now I have two questions: 1) http://wiki.dovecot.org/ACL states: "Mailboxes in public namespaces don't have owners, so by default no-one can access them." The same document, when explaining the meaning of the k flag in the ACLs, states: "Mailboxes can be created (or renamed) under this mailbox (there is no recursion, so creating a mailbox under this mailbox's child uses only the child's ACLs)" I have placed an ACL (dovecot-ACL) at the root of the public namespace (all rights to anyone). The public namespace was appearing correctly in my IMAP client. Then I have copied a large folder with hundreds of nested subfolders (nesting level > 3) from another account to the root of the public namespace. According to the documentation mentioned above, this should not have been possible (if I got the docs right): The first nesting level of folder should have been created, but not the messages in them and for sure not the deeper nested folders. There is no dovecot-acl within a single of the first level folders (I have verified this), so no one should have access to them. Nevertheless, in addition to the succesful copy, I can see every folder and every message in my IMAP client, I can delete and so on. Could some please explain if I got the docs wrong? 2) If there really is no ACL recursion, how are we supposed to copy large folder structures (perhaps thousands of folders, nested to 5 levels deep) to a public namespace? Do we need to create all folders by hand, then place the dovecot-acl in each folder, and then copy the messages to each folder by hand? Do we need to switch to global ACLs so that we can establish a master user for doing the act of filling the public space? Or is there a dovecot module which, immediately after creating a folder, looks into the parent folder of the new folder and copies the dovecot-acl from the parent folder to the new folder? Currently, I am very happy that dovecot didn't what it should do according to my understanding of the documentation (since I really needed to copy this folder structure to the public namespace), but on the other hand, I am a bit puzzled now not knowing if the documentation is wrong, my understanding of it is wrong or the source code is wrong :-) Thanks you very much for any help, Peter Here is the output of dovecot -n: # 1.0.15: /etc/dovecot/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot-info.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps listen: 192.168.20.23 ssl_cert_file: /etc/dovecot/imap-ssl.home.omeganet.de.crt ssl_key_file: /etc/dovecot/imap-ssl.home.omeganet.de.key ssl_parameters_regenerate: 24 ssl_cipher_list: ALL:!LOW login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_processes_count: 1 login_max_processes_count: 32 max_mail_processes: 32 mail_privileged_group: mail mail_location: maildir:~/Maildir mail_cache_fields: mail_never_cache_fields: mail_plugins: acl namespace: type: private inbox: yes namespace: type: public prefix: Archive. location: maildir:/home/vmail/archive:INDEX=~/Maildir/archive auth default: cache_size: 1 cache_ttl: 600 worker_max_count: 4 passdb: driver: passwd-file args: /etc/dovecot/passdb userdb: driver: static args: uid=vmail gid=vmail home=/home/vmail/%u socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: root plugin: acl: vfile -- GMX DSL: Internet, Telefon und Entertainment für nur 19,99 EUR/mtl.! http://portal.gmx.net/de/go/dsl02

[Dovecot] log_path and info_log_path - ownership of parent directory
by Phil Howard 07 May '10

The Ubuntu package didn't create the directory for these. What ownership/permissions are needed for it? Does it need to be owned by the dovecot user?
