[Dovecot] attachments not with email causing FETCH BODY[] failed
by Anand Kumria 05 Aug '13

05 Aug '13

Hi, Anyone else experiencing this (Dovecot 2.2.4, attachments stored separately): dovecot: imap(user(a)kamdha.com): Error: file_istream.open(/home/ example.com/user/attachments/f5/f0/f5f0f2c08c4311fa404d090a703c3b492f2ea718…) failed: No such file or directory dovecot: imap(user(a)example.com): Error: read(BODY[]) failed: No such file or directory (FETCH for mailbox INBOX UID 42501) dovecot: imap(user(a)example.com): Disconnected: FETCH failed in=186 out=86389 My dovecot.conf attachment related config is: mail_attachment_dir = /home/%d/%n/attachments mail_attachment_min_size = 128k mail_attachment_fs = sis posix mail_attachment_hash = %{sha1} So, questions: - anyone else experiencing this? - how might this occurred? - what is the best way to find the corrupted message? - how should I go about fixing this? Any help or pointers would be appreciated. Thanks, Anand

[Dovecot] Passing data safely in password_key?
by Attila Nagy 05 Aug '13

05 Aug '13

Hi, I would like to convert my custom POP/IMAP proxy to Dovecot's. In this proxy I do more than giving back user name, password and the host and I need extra information. Luckily all of them are available as variables, but more than one comes as user input (like user name and cleartext password) and I'm not sure how to pass them safely. Obviously I would need a separator, which is guaranteed not to show up either in user name and the cleartext password. Should I use escape (%E) here, or is there a better way?

[Dovecot] ACL not copied to new mailboxes
by Markus Weippert 05 Aug '13

05 Aug '13

Hi, I had some trouble with ACLs not being copied to new child mailboxes in dovecot 2.2.4. It doesn't matter whether it's a private, shared or public mailbox I create the folder in, the ACLs just seems to be ignored. Anyway, I debugged the executable and came up with the attached patch. Since I'm not a developer, I'm not 100% sure about this but it works for me now.

[Dovecot] [Metadata Plugin] Q: Source Repository
by Christoph Hintermüller 05 Aug '13

05 Aug '13

Hi I'm currently trying to package V14 of Metadata plugin for Ubuntu Quantal (https://launchpad.net/~privatedata/+archive/dovecot-2.2.2/) to be installed along with dovecot 2.2.4. According to my efforts packaging the plugin i do have some questions For future releases, is it possible to add a link to the current release on the meta data mercurial page which includes in the filename of the tar.gz archive the current version number of the plugin ( metadata-plugin-v14.tar.gz). That would allow to add an appropriate line in the debian/watch file to detect when a new release of the plugin is available. Currently i have to check mercurial page manually and use an updated version mangling entry to ensure that the packaging system downloads the latest version. The link would help to simplify this. Especially as the base link in my debian/watch file currently points to tip.tar.gz and not to the archive the linke of the V14 tag points to. The sources i got represent the tip.tar.gz downloaded on July 19th 2013 23:16 CET which likely do not exactly correspond to the contents of the archive containing sources of V14. Therefore a versioned link to the source archives of the latest version would simplify things a lot, especially adding patches released for the latest version. As well as reporting the following addition. Further I have added a doc directory stub, containing the configuration examples found in thread http://dovecot.2317879.n4.nabble.com/dovecot-metadata-8-released-tp10091.ht… Greetings Christoph

[Dovecot] Subfolders of Inbox with LAYOUT=fs
by Keith Edmunds 05 Aug '13

05 Aug '13

We've just converted to LAYOUT=fs. Some users had subfolders under Inbox, and for those users some MUAs no longer show those folders. The directory structure is that the cur, tmp and new folders are in the 'location' directory, but the subfolders are in $location/INBOX/$foldername. I am suspicious of this: 12 list "" INBOX * LIST (\HasNoChildren) "/" "INBOX" 12 OK List completed. I have tried moving the cur, tmp and new folders to $location/INBOX, and changing 'location' in dovecot.conf, but the subfolders still do not show. Question: is it legitimate to have subfolders of INBOX when using LAYOUT=fs? If so, what am I missing?

[Dovecot] Help needed with SOLR integration

Hi, Is there anything wrong with this config for getting SOLR working ? I'm on Ubuntu 12.04LTS and using the bundled Jetty and SOLR.

[Dovecot] Weird log entries when some users are composing messages in Thunderbird
by Charles Marcus 05 Aug '13

05 Aug '13

Hi all/Timo, When some of our users are composing a message in Thunderbird, I see a ton of these in the logs, and they keep repeating the entire time they are typing until the message gets sent... > 2013-08-05T10:34:42-04:00 myhost dovecot: imap-login: Login: user=<user(a)media-brokers.com>, method=PLAIN, rip=###.###.###.###, lport=993, mpid=8152, TLS, session=<El2GNTTjNgDAqAIc> > 2013-08-05T10:34:42-04:00 myhost dovecot: imap(user(a)media-brokers.com): Disconnected: Disconnected in IDLE in=149 out=12449 > 2013-08-05T10:34:42-04:00 myhost dovecot: imap-login: Login: user=<user(a)media-brokers.com>, method=PLAIN, rip=###.###.###.###, lport=993, mpid=8153, TLS, session=<lJedNTTjNwDAqAIc> > 2013-08-05T10:34:42-04:00 myhost dovecot: imap(user(a)media-brokers.com): Disconnected: Disconnected in IDLE in=149 out=12449 I confirmed that their 'Auto-Save' settings are the defaults (5 minutes, same as mine), and when I'm composing a message, there are no entries like this. The only other option I could think of that might affect t his is the 'spell check as you type', which is also enabled on mine. Also - I'm not sure this *always* happens to these users... all I know is, I see these flooding the logs sometimes, and when I remote in, that user is composing a message. Anyone have any idea why this happens to only a few of our users, and possibly only sometimes? Could it be something in the HTML of the quoted text when they are replying to certain messages? Thanks, -- Best regards, Charles
