[Dovecot] dot named folders
by Micah Anderson 12 Mar '12

12 Mar '12

When a user makes a folder called 'x.y' it actually creates a folder called 'x' with a folder called 'y' inside, rather than a folder called 'x.y'. I'm guessing this has to do with an internal folder separator namespace configuration, but I'm a bit confused by how this works. I'm using 2.0.15 with mdbox and this is what I have configured for my namespaces: namespace { separator = . prefix = inbox = yes } namespace { separator = . prefix = INBOX. inbox = no hidden = yes list = no } I migrated from courier maildirs, so perhaps I no longer need some of these now that the conversion is finished? thanks for any suggestions, I've got my head mixed up on this issue, micah --

[Dovecot] Extracting mbox format from Dovecot IMAP (mdbox)
by Giles Coochey 12 Mar '12

12 Mar '12

Hi, I'm looking for a quick tool that can connect to my IMAP account grab all the messages in a particular folder and dump them to a mbox format file? Anyone know a quick easy tool to do that? This is a spam folder that I'd like to do some Bayes spam learning on, but since I've migrated to mdbox I don't think I can do this directly on the mailbox. Any thoughts appreciated. -- Best Regards, Giles Coochey NetSecSpec Ltd UK Mobile: +44 7983 877 438 Business Email: giles.coochey(a)netsecspec.co.uk Email/MSN/Live Messenger: giles(a)coochey.net Skype: gilescoochey

Re: [Dovecot] Question about folder creation/delete and logging

mail_log plugin is just what we need, thank you for your support. Yes, we are using bacula+doveadm import for this project. If you are interested, we have in production an home-brew message-tracking system for our end-users. We parse qmail / postfix / clamav / spamassassin/ dovecot / sieve logs and insert them in a mysql database, and a logged user in our webapp can see what happened with her mails (sent mails or messages waiting for arrival). Affero GPL software, of course.

I guess you're using "doveadm import"? So other than that, haven't heard of any.

[Dovecot] Question about folder creation/delete and logging
by Maria Arrea 12 Mar '12

12 Mar '12

Hello We are working in a web based restore system for our Dovecot users. In this web form a user must log-in and after successful login can estore a deleted folder from date X. We will release it under the GPL. I have a couple of questions: - Is there any way of Dovecot logging to write when a folder is deleted or created? We do not want to increase too much our "normal" logging level. We use Dovecot 2.0.18+mdbox+zlib - Does anybody know of any other project to create an easy-restore for Dovecot? Regards Maria

[Dovecot] Dovecot LDA breaking .qmail forwarding?
by Wouter van der Schagt 12 Mar '12

12 Mar '12

Good morning all, I've a problem, I'm using the Dovecot LDA in my .qmail file: |/var/qmail/bin/preline -f /usr/local/libexec/dovecot/deliver -d $EXT@$USER However when I add a forward, such as: |/var/qmail/bin/preline -f /usr/local/libexec/dovecot/deliver -d $EXT@$USER <mailto:&wouter@vdschagt.com> &wouter(a)vdschagt.com The mail isn't forwarded and stays in the queue on the mail server, the same is the case when I reverse the lines. The error in the log file is: @400000004f5de5f7033bc434 delivery 824026: deferral: qmail-inject:_fatal:_qq_trouble_creating_files_in_queue_(#4.3.0)/system_erro r_calling_qmail-inject/ When using another LDA, for example when specifying the Maildir, it works, but then i cannot use Sieve scripts. Any ideas? Am I doing anything wrong? Sincerely, - Wouter van der Schagt

[Dovecot] Lock down Shared Mail Accounts?

This brings up a question I have been meaning to ask. One thing I want to do on my new converted system is to implement shared mail. There will be two different scenarios - users sharing 'folders', which looks to be fairly simple using virtual ACL files - but for the other scenario, I'm not sure about a specific requirement we will have... I want to give multiple people shared access to some actual accounts with all of the special use folders, with the following requirements: 1. They can all read/reply to new messages as they come in, 2. They use shared \seen, \replied and \forwarded flags, so once someone else has read/dealt with a message, the others see that, 3. When they reply to/forward a message, the Sent message gets saved to that accounts 'Sent' folder, 4. They can *move* messages to other folders in that account (ie, 'file' them), and last (this is the tricky part) 5. No one other than a designated user or users (Master User(s)? Users in a specified Group?) can delete any messages in this account, in any of the folders. These emails deal with financial transactions (AP and AR issues) and Faxes, thus the requirement to not be able to delete them. Can this be accomplished with the current state of things? Or would this require some coding? If the latter, could it be done as a plug-in, or would it require changes to the core code? Thanks, -- Best regards, Charles

Re: [Dovecot] dovecot Digest, Vol 107, Issue 20 Fscking warnings
by Stephen Davies 10 Mar '12

Yes that is the google thread that I saw. I don't see the relevance of your reference to dsync. As I read the man pages for dsync it is used to sync separate servers, to make backups or to convert mailbox formats. When I upgraded from 1.2.15 to 2.1.1 I saw nothing in the doco to suggest that dsync was relevant to my scenario. In a previous thread here (Log sync errors), Timo suggested that the migration fix was to delete all .imap directories. My understanding was that this should fix any differences between 1.2.15 files and 2.1.1. If that were the case, mentioning the migration again would seem irrelevant. However, it seems that deleting the .imap files did not fix the log sync errors or the fscking warnings. Both are still happening continuously.

[Dovecot] POP3C storage backend
by Tom Talpey 10 Mar '12

10 Mar '12

I see a new "POP3C" lib-storage client backend in dovecot 2.1, but I don't see anything in the 2.1 doc directory or in the wiki. Can this be used to synchronize dovecot with external pop servers? Doing away with my current fetchmail and lmtp solution for this would be quite interesting. Thanks for any pointers to configuring and using this, if so...
