[Dovecot] FS Quotas, what am I doing wrong?
by Kelsey Cummings 30 Aug '12

30 Aug '12

I'm not able to get the FS quota module to behave as I expect. Depsite having function fs quotas and dovecot apparently configured to use then, the quotas appear to be empty and/or not configured. Any clues? # quota kgc Disk quotas for user kgc (uid 500): Filesystem blocks quota limit grace files quota limit grace /dev/sda3 1229460 7000000 8000000 103776 5000000 6000000 # doveadm quota get -u kgc Quota name Type Value Limit % User user STORAGE 0 - 0 User user MESSAGE 0 - 0 # telnet 0 143 ...

[Dovecot] IMAP IDLE - iPhone?
by dovecot＠noboost.org 29 Aug '12

29 Aug '12

Hi All, Probably a very common question now days. I'd like to configure our iPhones at work to go directly to my dovecot server (currently dovecot-2.0.9-2.el6_1.1.x86_64). Using the IMAP IDLE (push email) protocol. Has anyone successfully deployed this? If yes, did you have to use an app from the Apple store? For me the IMAP process works, however it's clearly not notifying the client when new email is detected on the server. cya Craig

[Dovecot] Dovecot Director Output buffer full
by Dominic Malolepszy 29 Aug '12

29 Aug '12

Hi, I have been seeing the following messages in logs on all my Dovecot servers each running both a dovecot-director instance and a dovecot pop3/imap backend. These logs appear to relate to problems with the director. Aug 28 16:09:52 dovecot01 dovecot: director: Error: director(10.0.0.2:9090/right): Output buffer full, disconnecting Aug 28 16:10:01 dovecot01 dovecot: director: Error: Ring SYNC appears to have got lost, resending Aug 28 16:10:02 dovecot01 dovecot: director: Error: Director 10.0.0.2:9090/right disconnected Aug 28 16:09:51 dovecot02 dovecot: director: Error: director(10.0.0.3:9090/right): Output buffer full, disconnecting Aug 28 16:09:57 dovecot02 dovecot: director: Error: Ring SYNC appears to have got lost, resending Aug 28 16:10:01 dovecot02 dovecot: director: Error: Director 10.0.0.3:9090/right disconnected Aug 28 16:10:02 dovecot02 dovecot: director: Error: director(10.0.0.1:9090/left): Ping timed out, disconnecting Aug 28 16:13:15 dovecot02 dovecot: director: Warning: Delaying new user requests until ring is synced Note dovecot01 has IP 10.0.0.1 and dovecot02 has IP 10.0.0.2 and so on. This seems to show up when I enable the poolmon script (https://github.com/brandond/poolmon) on all the servers, and all servers start simultaneous logins to each others Dovecot backends. I did notice that the poolmon script has been flapping vhost weights a lot (I am looking at making the script handle transient errors better), which means that it is connecting to the dovecot-director socket every few minutes and changing vhost weights from 100 to 0 and vice-versa.

[Dovecot] Size of Mailbox affecting the sending of mail?
by Tim Smith 29 Aug '12

29 Aug '12

Hi, I didn't know where to post this one so I'll start off with you guys and then try Postfix if I'm barking up the wrong tree! Having set up my mail server (Dovecot/Postfix), users are experiencing long delays (a couple of minutes) when sending mail from mail client such as Thunderbird - this increases with attachments. Having had a brief discussion with someone, they mentioned that the reason that this may be to do with the size of the mailbox. I couldn't see the rationale behind this unless Dovecot is syncing the mailbox after every sent mail (due to possibly saving the sent item?) The mail is being delivered successfully but the amount of time it is taking to complete the action is far too long! Sorry this is a bit vague but any advice on trying to diagnose the problem would be appreciated. Thanks in advance! Tim

[Dovecot] quota: ignore deleted messages (?)
by Sven Hartge 28 Aug '12

28 Aug '12

Hi! I am currently in the process of preparing a migration of our old Courier-based IMAP/POP server setup to a Dovecot-based one. During this process I came across the following problem with the difference Courier and Dovecot handle deleted messages and mail quota. Quote from http://www.courier-mta.org/imap/README.maildirquota.html: ,---- | The default application configuration that uses this maildirquota | library does not count deleted messages, and any contents of the Trash | folder, against the quota. Messages that are marked as deleted (but not | yet actually removed), or messages that are moved to the Trash folder | (which is subject to automatic purging) do not count towards the set | quota. `---- Ignoring the content (or increasing the quota) of the Trash folder is easy and no problem, but ignoring deleted messages seems impossible without changes to the code. While deleted messages are still stored on the server and still take up space until they are expunged, counting them against the quota is somewhat counter-intuitive because most clients don't show those mails and the normal user is unaware the mails he deleted are still there and take up space. Worse yet, if the client uses move-to-Trash, a user deleting mails will double the used space (until Expunge is used) and this may push him over his quota and thus cause any new mail delivery to fail. Unfortunately as our users are used to the courier way of handling the quota this will cause trouble after the migration. And this setup is run at a University, so I don't have any control over the clients a user uses and the behavior of said clients so I am not able to disable the move-to-Trash feature or force an immediate Expunge after a delete. So I propose an additional flag for the quota_rule config option to be able to enable a more lax interpretation of the quota enforcement: quota_rule = *:storage=1G:ignoredeleted quota_rule2 = Trash:storage=+100M Of course I would then have a nightly cronjob which force-expunges all deleted messages so that users can't store mails infinitely in their mailboxes. Thanks for your time and Grüße, Sven. -- Sigmentation fault. Core dumped.

[Dovecot] Deleting metadata smashes file dovecot.dict
by Andre Gröbe 28 Aug '12

28 Aug '12

Hi, I am using dovecot (see dovecot -n output below) with metadata plugin in my own plugin. I want to insert and delete some large metadata (>4KiB). It seems, that the delete in a second call of my plugin smashes the file dovecot.dict in users dir: 1st call: *dovecot.dict is empty -delete metadata 1 -delete metadata 2 -insert metadata 1 ~8KiB -insert metadata 2 <1KiB *dovecot.dict contains two entries 2nd call: -delete metadata 1 -delete metadata 2 -insert metadata 1 ~8KiB -insert metadata 2 <1KiB *dovecot.dict contains the two entries + some waste If all eight steps are called together (in the same plugin context) the file dovecot.dict seems to be ok. I have created a test plugin to reproduce this behaviour: <http://temp-share.com/show/dPf3myu5W>. It needs the notify and (patched) metadata plugin to run. To get it work i copy an email from one IMAP folder to another (to trigger the copy notifier). It seems, that there is an issue on writing metadata/dict, can anybody reproduce it or knows what is wrong? TIA -- Andre

[Dovecot] Sieve/pigeonhole rejects email addresses for valid UNIX users
by David Anderson 28 Aug '12

28 Aug '12

Self-explanatory, I hope (note the period on the end of the username); sieve/pigeonhole does not allow you to have senders which end with a period, which means that any UNIX users with such usernames who send mail have it rejected by sieve: # useradd testuser. # su - testuser. $ mail david(a)example.com -s 'testing' 123 . [testuser.@levi ~]$ logout # less /var/log/maillog Aug 22 07:50:56 levi dovecot: lda(david(a)example.com): Error: sieve: envelope sender address 'testuser.(a)myhost.example.com' is unparsable Versions: dovecot-pigeonhole-0.2.6-21.el5 dovecot-managesieve-0.2.6-21.el5 dovecot-2.0.18-1_134.el5 Why would anyone have a UNIX username ending in a period? For one, web hosting companies may use your domain name as your username - but be subject to a 32-character limit, so your domain name gets truncated.

[Dovecot] use sieve plugin with variable and folders
by Alano Conraz 28 Aug '12

28 Aug '12

Hello , I'm trying to use the pigeonhole plugin but I'm experiencing configuration problem... Hope you could help me! Firstly : my sieve filter test is the next one : /////////////////// require ["fileinto" , "variables" , "mailbox"]; if address :matches "Delivered-To" "*(a)*.*" { fileinto :create ".INBOX.iop" ; stop ; } //////////////////// I get in the log the following : "error: msgid=<****>: failed to store into mailbox '.INBOX.iop': Invalid mailbox name" And the email is stored in the INBOX (implicit keep was successful) I checked that "lda_mailbox_autocreate" and "lda_mailbox_autosubscribre" are set to "yes". Then , when this problem be solved, I would like to know if it is possible with the sieve plugin to implement the following algorithm : - extract the address from the header field "Delivered-To" and set the variable $delivto to this previous value. - extract the address from the header field "To" and set the variable $to to this previous value. - compare $delivto and $to : if they are diffrent, then redirect the email in the subfolder .INBOX.iop. Thank you for any help!

[Dovecot] plugin development: retrieve username -d -f inside plugins
by Alano Conraz 27 Aug '12

27 Aug '12

Hello, i don't know if it a the right place to ask my question related to the development of dovecot plugins, please correct me if it is not. I'm trying some dovecot plugin development. I did a little plugin that suit my needs but i'd like to go further now... I would like to know if there is a kind of "getenv" function that I could call to retrieve in my plugin the username of the mailbox being delivered by dovecot-lda or served by imap server. For example, when I use the deliver with "cat file.txt | deliver -d " user(a)domain.net" -f "me(a)domain.net" I would like to call a function that could return for me the argument of "-d" or "-f". i'm working with dovecot 2.0.17 by now. Thank you

[Dovecot] dsync replication available for testing
by Timo Sirainen 25 Aug '12

25 Aug '12

In dovecot-2.1 hg you can now test dsync-based replication. Everything isn't finished yet, but it appears to work and I've enabled it for my @dovecot.fi mails. Some issues: - public namespace isn't replicated at all - shared namespace is replicated, but not private mail flags - I've only tested SSH replication setup now, not director replication setup (and director setup is still missing many things) - SSH replication setup uses aggregator process, which isn't really necessary and can probably be avoided in future Below is a configuration for virtual user setup. System user configuration works pretty much the same, except doveadm/ssh is run as root. Try first that dsync works successfully with ssh in host1: doveadm sync -u user@domain remote:vmail@host2.example.com and also in host2: doveadm sync -u user@domain remote:vmail@host1.example.com ------ mail_plugins = $mail_plugins notify replication service aggregator { # give enough permissions for mail processes fifo_listener replication-notify-fifo { user = vmail mode = 0600 } unix_listener replication-notify { user = vmail mode = 0600 } } service replicator { # start replication at startup process_min_avail = 1 } plugin { # host1 replicates to host2 mail_replica = remote:vmail@host2.example.com # host2 replicates to host1 #mail_replica = remote:vmail@host1.example.com } #dsync_remote_cmd = ssh -l%{login} %{host} doveadm dsync-server -u%u -l%{lock_timeout} -n%{namespace} service doveadm { # if you're using a single virtual user, set this to # start ssh as vmail (not root) user = vmail }

[Dovecot] Shared mdboxes
by Wagner Michel Martins de Azevedo 24 Aug '12

24 Aug '12

Hi Timo, I'm trying to share two folders. The first one it's public and the other is per user based, using acl's to control access etc . Dovecot create the folders, but when I'll subscribe using ThunderBird client both of them seens like watermarked and has a "mailboxes" folder inside. I can set up the acl's rules using Thunderbird. Log files like mail.log don't show nothing in special and mail.err has nothing. Here is the config. # 2.1.8 (b4cd382b6606): /etc/dovecot/dovecot.conf# OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.5 /etc/dovecot/conf.d/10.mail.conf namespace { type = public separator = . prefix = public. location = mdbox:/var/mail_shares/public:INDEX=/var/mail_shares/public subscriptions = no}namespace { type = shared separator = . prefix = %h/shared location = mdbox:%h/shared:INDEX=%h/shared subscriptions = no list = children} Thanks, Wagner Azevedo

[Dovecot] enabling per user quota plugin and problems with pop3
by Angel L. Mateo 24 Aug '12

24 Aug '12

Hello, I am configuring quota plugin per user, not for the whole system. As documentation says (http://wiki2.dovecot.org/Quota) I have to add "quota" to the global mail_plugins and "imap_quota" to mail_plugins for protocol imap, but I don't know how to configure this in a userdb. I'm using a passwd-file in the way: <user>:{plain}password:<uid>:<gid>::<home>::userdb_mail_plugins=quota,imap_quota but this activate both plugins in the global mail_plugins option. The problem with this is that if the user tries to connect via pop3 instead of imap (a thing that I permit, although the user shouldn't do it) I have the error: Aug 20 10:04:18 myotis30 dovecot: pop3: Error: dlopen(/usr/lib/dovecot/modules/lib11_imap_quota_plugin.so) failed: /usr/lib/dovecot/modules/lib11_imap_quota_plugin.so: undefined symbol: client_send_tagline is there any way to solve this problem? -- Angel L.

[Dovecot] userdb multiple databases
by Angel L. Mateo 23 Aug '12

23 Aug '12

Hello, I'm trying to configure per user plugins. My original passdb and userdb is in a ldap directory (using userdb with prefetch). To configure per user plugins (in fact, I want to enable quota plugin for some users) I need to configure mail_plugins attribute in the userdb. The problem is that I don't know any ldap attribute to store this information (is there any schema with includes an attribute for this). So I want to configure it in a passwd-file file. My problem is that I don't know if I can chain userdb databases. I know I can configure multiple databases, but as far as I know, they are looked in order, so if the user is found in the first one, then is no look for the user in the second one, so I have to configure all user's attributes in the passwd-file database. Is there any way to chain these lookups? -- Angel L.
