[Dovecot] Problems with acl and shared namespace
by Udo Lembke 06 Jul '11

06 Jul '11

Hi, i'm a dovecot-newbie and also new at this mailinglist. I'm try to configure an mailserver with dovecot2, postfix and postfixadmin. At this time i struggle with acl and shared namespace. My goal is, that every user get an archive-area on an separate storage without quota (quota isn't running yet). With: namespace { type = private separator = / prefix = "archiv/%u/" location = maildir:/var/data/archiv/%d/%n:INDEX=/var/data/indexes/archiv/%u:LAYOUT=fs inbox = no subscriptions = yes list = yes } I see the folder, but i can't subscribe them (with thunderbird, or roundcube). With roundcube i can add a new folder below - so i use the trick autocreate5 = archiv/%u/archiv autosubscribe5 = archiv/%u/archiv This is as workaround ok - or is this a "must be"?. But the user should also be able to share parts of the archiv-mailbox with other users (partly on different domains). If i change the type of namespace to shared, i can't access the archiv-folder. The logfile shows problems with the acl (but also with private namespace): Jun 30 11:15:11 imap(test(a)example.com): Debug: Namespace : type=shared, prefix=archiv/test(a)example.com/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes location=maildir:/var/data/archiv/example.com/test:INDEX=/var/data/indexes/… Jun 30 11:15:11 imap(test(a)example.com): Debug: fs: root=/var/data/archiv/example.com/test, index=/var/data/indexes/archiv/test(a)example.com, control=, inbox= Jun 30 11:15:11 imap(test(a)example.com): Debug: acl: initializing backend with data: vfile Jun 30 11:15:11 imap(test(a)example.com): Debug: acl: acl username = test(a)example.com Jun 30 11:15:11 imap(test(a)example.com): Debug: acl: owner = 0 Jun 30 11:15:11 imap(test(a)example.com): Debug: acl vfile: Global ACL directory: (none) Jun 30 11:15:11 imap(test(a)example.com): Debug: Namespace : Using permissions from /var/data/mail/example.com/test: mode=0700 gid=-1 Jun 30 11:15:11 imap(test(a)example.com): Debug: acl vfile: file /var/data/archiv/example.com/test/dovecot-acl not found Jun 30 11:15:11 imap(test(a)example.com): Debug: autocreate: Failed to create mailbox archiv: Permission denied Jun 30 11:15:11 imap(test(a)example.com): Debug: Namespace archiv/test(a)example.com/: Using permissions from /var/data/archiv/example.com/test: mode=0700 gid=-1 Jun 30 11:15:11 imap(test(a)example.com): Debug: acl vfile: file /var/data/mail/example.com/test/dovecot-acl not found I'm wondering about "...dovecot-acl not found" because dovecot create an file "dovecot-acl-list" : # ls -l /var/data/archiv/example.com/test/ drwx------ 5 dovecot dovecot 4096 30.

I use 2.0.13 for testing. I put my config at the end of the mail. I'm happy if someone can hit me in the right direction, where i make the mistake.

[Dovecot] Dovecot 2.0.13 problem with LMTP
by Innocenzi, Cinzia 05 Jul '11

05 Jul '11

Hello, we have dovecot 2.0.13 installed in our RHEL5 servers. We use dovecot as a lmtp proxy on the front end mail relays and dovecot for back end lmtp/pop/imap. All our servers have RHEL5.6 64-bit and dovecot 2.0.13 installed, and the back end has also an ext3 mbox file-system mounted. Sometimes we have mails that get stuck on our postfix queue with the following error: Remote server not answering (timeout in DATA input) (in reply to end of DATA command) In our logs we only see the fact that the connection times out after 1 minute and gets disconnected: Jun 22 11:56:53 back-end dovecot: lmtp(3256): Connect from a.b.c.d Jun 22 11:57:53 back-end dovecot: lmtp(3256): Disconnect from a.b.c.d: Connection closed Jun 22 11:56:53 front-end dovecot: lmtp(16397): Connect from a.b.c.d Jun 22 11:57:53 front-end dovecot: lmtp(16397): Disconnect from a.b.c.d: Disconnected for inactivity We've tried to recalculate the mbox quota using "doveadm quota recalc -n ..." command and flushed our mail queue, but the mail still gets stuck on the postfix queue with the same error. It doesn't happen for every single mail, it's random. I'm attaching the output of dovecot -n for both servers. Can you please help us?

[Dovecot] Exim and Dovecot2 SASL: 435 Unable to authenticate at present
by Sergey Urushkin 04 Jul '11

04 Jul '11

Hi. I had working Exim 4.71 and Dovecot 1.2.9 SASL configuration on Ubuntu Lucid, but needed some features from dovecot2, so I installed 2.0.13 from https://launchpad.net/~carsten-uppenbrink-net/+archive/dovecot2 . Now I get Subj error while trying to authenticate via dovecot auth-client socket. However IMAP auth works fine with 2.0.13 and smtp auth worked fine until upgrade, so I think there is something wrong with dovecot2. Dovecot logs stay empty even with auth_debug*, just one string "auth: Debug: Loading modules from bla...". But here is another information that may help. And if it's needed I can build dovecot myself to ensure that ppa-build isn't guilty. Or debug some another way. Thanks. dovecot -n: # 2.0.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-31-server x86_64 Ubuntu 10.04.2 LTS auth_debug = yes auth_debug_passwords = yes auth_mechanisms = plain login apop

[Dovecot] Dovecot 2.0, mysql and quota

Hello all, I have some troubles to make the quota_check working with dovecot 2.0. My config is the following: postfix, dovecot as lda, mysql as virtual mailuser backend, and postfixadmin for the mailuser administration.

I have also checked the query it does to mysql, is the following SELECT maildir, 51 AS uid, 51 AS gid, CONCAT('*:bytes=', mailbox.quota ) AS quota_rule FROM mailbox WHERE username = 'testquota(a)mediaservice.pri' AND active = '1' And the result, is the following: +-----------------------------+-----+-----+-----------------+ | maildir | uid | gid | quota_rule | +-----------------------------+-----+-----+-----------------+ | mediaservice.pri/testquota/ | 51 | 51 | *:bytes=1024000 | +-----------------------------+-----+-----+-----------------+ Seems right to me...but it is not working.... why? Ah, this is the content of the quota_warning.sh: #!/bin/sh PERCENT=$1 USER=$2 cat << EOF | /usr/local/libexec/dovecot/dovecot-lda -d $USER -o "plugin/quota=maildir:User quota:noenforcing" From: postmaster(a)mediaservice.pri Subject: quota warning Your mailbox is now $PERCENT% full.

[Dovecot] NFS mail storage
by Daniel L. Miller 30 Jun '11

30 Jun '11

The parameters listed for nfs installations (mmap_disable, doctlock_use_excl, mail_nfs_storage, mail_nfs_index) - are they necessary for data integrity, and/or do they compensate for NFS latency and improve performance? My understanding is the indexes are a critical part of a dbox storage, but on the other hand having local indexes is a major performance consideration. Is maildir a "better" choice under NFS than dbox? -- Daniel

[Dovecot] dovecot, mdbox and indexes
by Angel L. Mateo 30 Jun '11

30 Jun '11

Hello everybody, We are updating our old dovecot 1.1 servers to 2.0. We have a farm os servers, with users in nfs filesystems and indexes in local fs. Mail is stored in maildir format. We don't warrant that a user is always directed to the same server, although our load balancer sends all request from one IP to the same server (during a session time with a inactivity timeout). This is the second scenario described at http://wiki2.dovecot.org/NFS. We are now trying to migrate to the third scenario and using mdbox. As an intermediate step, we have configured this second scenario, but with indexes in NFS filesystems. The configuration is: * mmap_disable = yes * dotlock_use_excl = no * mail_nfs_storage = yes * mail_nfs_index = yes * lock_method = fcntl (we have also tried with dotlock) This configuration works without any problems with few users, but with high load, we have a lot of lock timeouts error like: Jun 29 10:24:04 myotis34 dovecot: imap(mpm): Error: Timeout (180s) while waiting for lock for transaction log file /home/pas/01/014601/maildir_indexes/.INBOX/dovecot.index.log These errors cause a corrupted index and we have to manually delete the user's index so he could read his mail again. So we are planning to configure the third scenario. In this configuration, we don't have any problem during our tests if we use maildir format. But if we use mdbox one, we have problems when we have to change the final server for the server (We allways send the user to the same final server, but sometimes, if the server is down, for example, this is not possible). The tests we have done (with POP) are: * I connect to "my" server. There's no problem. I have my mail. I delete a mail. * I connect then to a server that have no index for me. The only problem is that the previously deleted mail appears again. * I connect then to a server with an outdated index: this is the problem. I have only the messages in that outdated index. The mail received since then has disappeared (although I could receive new mail). How could I solve this problem? Is this really a problem? Should I use a shared storage for indexes? What is the best configuration for a high availability service? -- Angel L.
