I created the file 'dovecot-shared' in the shared folder (I also updated the Wiki to make the procedure a little bit clearer). I couldn't seem to figure out a good way to make it read only though. So I still can't seem to get the namespace method working. I also tried pointing the location at an mbox and that did not work. In the client I can see the Public folder listed but it is grayed out and won't let me subscribe. Any thoughts? Thanks, John

I don't think that UW-IMAP was expunging messages because I could open up the mbox with pine and see all of the messages flagged as "Deleted" but not yet expunged. And when I try a similar test with Fastmail.fm (delete the message in Mail, then check using the web interface) the mail is marked as deleted in the web interface and does not show up in Mail.app but the messages are re-numbered appropriately. Granted, I have no idea how Mail.app does its numbering (especially since Thunderbird doesn't have message numbering), but is it possible that there's more information that the IMAP server should be sending back that Dovecot isn't? I've attached a screenshot from my Mail.app that shows the numbering issue. The gaps in the message sequence are where a deleted (but not expunged) message was. jcn

[Dovecot] Mac mail copy/delete problems w/1.0b2
by Tony Kay 08 Feb '06

08 Feb '06

Hi, Mac mail (a horribly mis-behaved client, it seems), has a horribly hard time deleting/copying large blocks of messages from one folder to another. The basic symptom is: 1. Select a bunch of messages 2. Click on delete 3. Wait for a _very_ long time. It also seems very slow on copying, so it may be the "trash folder copy on delete" that is really slowing it down. Anybody else seen this? -- Anthony Kay University Computing Center (541) 346-1719 GPG Fingerprint: B0DB D46A 60AF FAE7 A94A 5075 0CB4 4D88 9F4F 7F09 The best way to have a good idea is to have a lot of ideas.

[Dovecot] Dovecot does not access /var/mail when using Maildir
by mirko＠mirkonet.nl 08 Feb '06

08 Feb '06

Hello, I'm running debain on my machine with postfix, squirrelmail and dovecot installed. Everything works fine and I'm able to access my mail via squirrelmail and via Outlook with imap. However I want to create subfolders what is not possible. After reading I discovered that I use mbox and that maildir is needed in order to be able to use subfolders. I have created a Maildir folder with the maildirmake.dovecot command in my /home/mirko directory and corrected the owner. Now dovecot uses the Maildir and I can create subfolers. However my problem is that I don't receive Emails in my Inbox. Incoming mails are delivered to /var/mail/mirko, but when dovecot uses Maildir it doesn't access this. I have played with the default_mail_env settings in dovecot.conf which does influence the use of mbox or Maildir. However the problem remains: As soon as Maildir is used, the Inbox is empty and I don't receive Email. Is there a way when Maildir is used to point dovecot to /var/mail/ for the incoming Email? Or do I something else wrong? Your help is appreciated. Greetings, Mirko

[Dovecot] Out of memory problem
by Neil Wilson 08 Feb '06

Hi guys, Running SuSe 9.3 with dovecot 1.0.alpha3 source installation. One of the users has quite a lot of important email in a folder, but when he trys to view this folder, it either sits and waits, and then times out, or just logs out straight away. Looking in the log(/var/log/mail), I'm getting the following error.

My next step is to upgrade to the latest version of dovecot, but this is quite a large company, and I will need to wait until after hours to do the upgrade. Any help would be greatly appreciated.

[Dovecot] How to have a "public" readonly folder?
by Villalovos, John L 08 Feb '06

08 Feb '06

I searched the website and the mailing list and had difficulty finding an answer. I have my email users who are using dovecot-1.0.beta2. I also have setup a dummy account to get the Linux Kernel Mailing List (LKML) traffic. I would like to have it so that my IMAP users (maybe POP3 but don't need that) be able to read the LKML mailing list from that email account. I can put the email into an mbox or a maildir for the LKML mail. I have played around with the namespace and public option and I can't get it to work :( I tried this: namespace public { separator = / prefix = Public/ location = maildir:/home/virtemail/lkml/ } In my email client (Mozilla Thunderbird 1.5), I am unable to view the Public folder. If I select subscribe, I can see the Public folder but it is grayed out. Any ideas? Thanks, John

[Dovecot] Re: MySQL client out of memory error

Alexander - We had this exact same issue with MySQL authentication. We resolved it by changing this entry in the auth section of the dovecot.conf: # Number of authentication processes to create #count = 1 We set count=20, and then through testing lowered it to count=10. This starts 10 auth-worker processes and to this point we have not had problems with the out of memory condition. -- Roger J.

[Dovecot] Mixed IMAP/POP3 environment: further informations
by Denis Sbragion 07 Feb '06

07 Feb '06

Hello All, some further information. While waiting for some info I'm rolling back to UW and I discovered that if I delete the user "~/Maildir" automatically created by Dovecot, so including any index, the POP3 server works as expected. So it isn't the "Status" flag stored in the mbox file that prevents the download but some status information stored in the IMAP indexes created by Dovecot. I've retried this a couple of times to be sure. Does this helps? Bye, -- Denis Sbragion InfoTecna Tel: +39 0362 805396, Fax: +39 0362 805404 URL: http://www.infotecna.it

[Dovecot] Dovecot index issues (Solaris/Thunderbird)
by Mario Nigrovic-rvvk40 07 Feb '06

07 Feb '06

Folks - My setup is that my mail is filed (by procmail) in ~/.mail/Maildir, an NFS filesystem. But I'm running Dovecot (1.0alpha5) on my local machine (as myself on port 2143), just to serve this mail to my browser (Thunderbird 1.0.2). The NFS data is on a netapp which seems to be creating .nfs files LIKE CRAZY. I expect these are the remnants of lock files, so I'm trying to move my indexes onto local disk. To that end, I've created /var/tmp/mario/dovecot and put the following into my dovecot.conf: default_mail_env = maildir:%h/.mail/Maildir:INDEX=/var/tmp/mario/dovecot Dovecot happily makes index files, but then fails to serve some of my subscribed folders! Thunderbird is less than helpful in telling me what's going wrong, but dtmail shows that dovecot is reporting "out of sync" and a couple other errors (UID out of sequence), then closing the connection (for those folders). This may happen only after Thunderbird has tried to open the folder that I see these errors with dtmail: Dovecot ready. [UNSEEN 227] First unseen. [UIDNEXT 341] Predicted next UID IMAP connection broken (server response) No-op dead stream [CLOSED] No-op dead stream I've turned mmap off and set locking to fcntl. As a last resort, I've turned indexes off default_mail_env = maildir:%h/.mail/Maildir:INDEX=MEMORY but this makes thunderbird reload all headers every time I open a folder, which takes a very long time. Any suggestions? How do I debug this further? Mario

[Dovecot] passwd-userdb with args
by Thomas Wouters 07 Feb '06

07 Feb '06

I'm not sure why the 'passwd' userdb didn't allow args, but it meant (for instance) that the quota plugins weren't usable. I spent quite a bit of time trying to get my new quota-rquotad plugin to work, only to find out that it was my 'quota=rquotad:<filesystem list>' argument that wasn't being passed to the imap child :) The attached patch implements arguments for the 'passwd' userdb, just like it exists for the 'static' userdb (in fact, mostly copy-pasted from 'static'.) It doesn't try to avoid clashing with the values found in the passwd-struct, but I suspect it ends up overwriting them. That could probably be a feature ;) I don't use the passwd-file userdb, but that one would probably also enjoy being argified. -- Thomas Wouters <thomas(a)xs4all.net> Hi!

[Dovecot] dovecot rpms, .subscriptions file, mbox to maildir
by Saurabh Barve 07 Feb '06

07 Feb '06

Hi, I am running dovecot 0.99-14 on a Fedora Core 2 machine. I had a few questions: 1) I wanted to upgrade to the dovecot-1.0 release. However, I am not sure if that's really required. dovecot-0.99-14 has been running very well for me for quite some time. Is there a real advantage to switching to the latest release. The reason I'm asking this is because: i) I don't have too many users to server - around 15 only. ii) My mail server is a pretty fast machine (~1 GHz, 1 GB RAM) machine, so hardware isn't too much of an issue. iii) I like to install software from rpm's. It's not that I can't install from source, but installing from rpm's makes it much easier for me. Just a personal preference. The version of dovecot that I am running was obtained from Dag Wieers web site. I haven't seen a newer version there. I've googled for rpm's for newer versions, and they are available, but I don't want to install it from some third party source that I don't know/trust. iv) I am also planning to support web mail for my users (probably through Squirrelmail). Are there any advantages/disadvantages to upgrading dovecot for that? v) People use Mozilla Mail, Mail.app, Thunderbird, Outlook, and Opera. Does the 1.0 version provide better integration with different mail clients (even though I understand that sometimes it's a problem with the client implementation). So, are there newer version of dovecot (1.0-stable) available in rpm formats which are guaranteed to be safe and un-trojaned? And is there any really good reason why I should upgrade to 1.0-stable? 2) My second question is about creating the .subscriptions (or subscriptions in 1.0) file. When I moved people over from using pine to using a mail client like Evolution/Thunderbird, I had to create .subscriptions/.mailboxlist file for them so that they could see the folders that they had created in pine. However, people still sometimes access e-mail using pine. They then create new folders in pine, which they are unable to see in their mail client. Is there a way around it? This occurs especially when people check their mail at the start of the month, and pine asks about saving/deleting old sent-mail folders, Trash folders. Is there a way to add these folders automagically to the .subscriptions file? 3) Would I be able to support web mail using mailboxes in mbox format, as I have them now? Or do I have to go for Maildir format? Since our university introduced web mail, they have had two sets of folders - one with capitalization (Sent, Deleted Messages, etc.) and one without (sent-mail, etc. - these were from our pine days). Is this due to web mail? Also, if I do need to convert from mbox to Maildir, what is the standard tool for doing that? I saw at least three different tools/scripts for doing that (mbox2maildir,mb2d,mb2md-2,mb2md.pl, .. ). Which tool (and from where) should I use to convert mailboxes without problems? Any help is greatly appreciated. Thanks in advance, Saurabh. ----- sa(a)atmos.colostate.edu

[Dovecot] Newbie question

Hi, Finally I managed to build (as ordinary user in my home dir) 1.0b2. (remember, I had problems with db-ldap.h disappeared after compile) What is the (simplest and) safest way to shut down dovecot on the live server and replace the running 0.99.14? I run OpenBSD 3.7 on Sparc. The last step would be 'make install', of course. To shutdown dovecot the last time I resorted to kill processes but I felt I had missed something... the install page (http://wiki.dovecot.org/BasicInstall) says to kill it, it feels a little crude; no nicer signals to send?

Hello, we have about 120 servers doing some million mails per day. Most of them use dovecot for pop and imap. In version 1.0.alpha4 we have dovecot-crashes on one or two of the machines in a week where dovecot log says "Panic: key not found from hash" and dovecot dies. We tried version 1.0.beta2 on some machines but with that we have another problem where log says "Error: auth-worker(default): sql((USER),(IP)): Password query failed: MySQL client run out of memory" and the auth process dies. Couldn't find anything usefull on that on the net so i'll ask the list bevor i'll post a bug report. ==================== /etc/dovecot.conf ==================== # dovecot pop3 + imap config (rpm) # SG PN HJM 2005-09-09 ## Main protocols = imap imaps pop3 pop3s # protocols = pop3 pop3s ssl_disable = no ssl_cert_file = /etc/ssl/cert ssl_key_file = /etc/ssl/key disable_plaintext_auth = no log_path = /var/log/dovecot ## Login processes login_processes_count = 2 login_max_processes_count = 128 login_max_logging_users = 256 # Greeting message for clients. login_greeting = Dovecot ready. ## Mail processes max_mail_processes = 1024 verbose_proctitle = yes verbose_ssl = no first_valid_uid = 500 last_valid_uid = 0 first_valid_gid = 0 last_valid_gid = 0 mail_extra_groups = mail_debug = no #default_mail_env = #mail_save_crlf = no #mmap_disable = no #lock_method = fcntl #maildir_stat_dirs = no #maildir_copy_with_hardlinks = no #mbox_read_locks = fcntl #mbox_write_locks = dotlock fcntl #mbox_lock_timeout = 300 #mbox_dotlock_change_timeout = 30 #mbox_dirty_syncs = yes #mbox_very_dirty_syncs = no #mbox_lazy_writes = yes #umask = 0077 #mail_drop_priv_before_exec = no #mail_process_size = 256 #mail_log_prefix = "%Us(%u): " ## IMAP specific settings protocol imap { imap_max_line_length = 65536 login_greeting_capability = no imap_client_workarounds = outlook-idle mail_use_modules = yes mail_modules = /usr/lib/dovecot/imap } ## POP3 specific settings protocol pop3 { pop3_no_flag_updates = no pop3_enable_last = yes pop3_uidl_format = %08Xu%08Xv pop3_client_workarounds = outlook-no-nuls oe-ns-eoh mail_use_modules = yes mail_modules = /usr/lib/dovecot/pop3 } ## Authentication processes auth_verbose = no auth_debug = no auth_worker_max_count = 30 auth default { mechanisms = plain # SQL database - normal passdb sql { args = /etc/dovecot-sql.conf } # SQL database - normal userdb sql { args = /etc/dovecot-sql.conf } user = root count = 1 } ==================== /etc/dovecot-sql.conf ==================== driver = mysql connect = host=/var/lib/mysql/mysql.sock dbname=(DB) user=(DBUSER) password=(DBPWD) default_pass_scheme = CRYPT password_query = SELECT pwhash AS password, user FROM mail_mailboxes WHERE (user = '%n' AND active = 'Y' AND (type != 'smtp') AND (type = 'imap' OR '%s' = 'pop3')) OR (mainuser = '%n' AND user = CONCAT('%n','mail0') AND (type != 'smtp') AND (type = 'imap' OR '%s' = 'pop3')) user_query = SELECT location AS home, uid, gid, user AS system_user FROM mail_mailboxes WHERE (user = '%n') OR (mainuser = '%n' AND user = CONCAT('%n','mail0')) ==================== table structure ==================== CREATE TABLE mail_mailboxes ( mainuser varchar(128) NOT NULL default '', domain varchar(128) NOT NULL default '', user varchar(128) NOT NULL default '', addr varchar(128) NOT NULL default '', type set('pop3','imap','smtp') NOT NULL default 'pop3', active set('Y','N') NOT NULL default 'Y', pwhash varchar(255) NOT NULL default 'unset', quota int(11) NOT NULL default '0', location varchar(255) NOT NULL default 'unset', uid int(11) NOT NULL default '0', gid int(11) NOT NULL default '0', PRIMARY KEY (user) ) TYPE=MyISAM;

[Dovecot] Mixed IMAP/POP3 environment and message status flags
by Denis Sbragion 06 Feb '06

06 Feb '06

Hello All, I'm trying to migrate from UW Imap to Dovecot (latest 1.0 beta 2). The target is to go from the actual environment (Eudora + POP3) to a web based IMAP environment (IMAP + SquirrelMail). While migrating we will need to keep both environments for some time, with users having both the ability to use Eudora through POP3 while in the office and also the ability to check e-mail using the web based interface from time to time when they are out of office. Everything seems to work pretty well except for one little quirk. Whenever new mail messages are checked on-line through IMAP they are marked with "Status: O" or "Status: RO" in the main INBOX file (which is kept in the old mbox format now, and is one of the many reasons for the Dovecort choice). This is correct following the RFC standards but after that the POP3 server seems to completely ignore any message marked as "O" or "RO", making it impossible to download previously seen/read messages through Eudora. I've checked any available Eudora and Dovecot setting, including the pop3_no_flag_updates flag, but so far nothing worked. Looking at mailing list archives it looks like this behaviour is intentional and has been introduced to work around some problems with Eudora when the "Leave mail on server" option is enabled. Nevertheless it seems there's still something wrong. UW Imap seems to get this right, it lets Eudora download the already read message, which are correctly downloaded already marked as read. I haven't been able to identify the source of the problem, i.e. if it is either an Eudora problem which UW circumvent in some way or a real Dovecot problem. I'd really like to move to Dovecot, which provides many feature which are really useful for our situation, expecially maildir folders, which are fast and much more "differential backup" friendly than single file mailboxes. Unfortunately this IMAP/POP3 interaction problem would be a major showstopper because it will prevent a smooth migration from the old environment to the new one. Any hint about this issue? Anybody faced a similar problem so far? Thanks in advance for any help, and my compliments for the excellent job performed so far. Dovecot seems to be the right tool to fill the gap between the simpler UW and the Cyrus monster. Keep on going! :) Bye, -- Denis Sbragion InfoTecna Tel: +39 0362 805396, Fax: +39 0362 805404 URL: http://www.infotecna.it

Hi Timo et all. At last I found with unix socket wouldn't connect and it works now. However after auth, imap crashes with signal 6. This happens on 1 machine, the other (unixware too) work fine.
