[Dovecot] Something other than dotlock for uidlist locking?
by James Berry 10 Aug '06

10 Aug '06

If I read the code correctly, only dotlocks are supported for locking of dovecot-uidlist. And I don't see any settings in the config file for it. As it turns out, dotlocks are very slow on my system, due to their implementation via hardlinks. Would it be possible to support other locking mechanisms for locking of the uidlist file? -jdb

[Dovecot] Public Namespace & ACL & Virtual Users
by Fintec 01 Aug '06

01 Aug '06

Background: I am wanting to create shared folders (public namespace) with access control lists on the sub directories. Our implementation of dovecot (v1.0b7) uses many virtual users and domains and 1 actual user (vmail), all using maildir. So far I have successfully created the public namespace (Public_Folders) which every user can access but I'm having difficulty restricting access using ACls. When trying to implement the dovecot ACL plug-in I followed the wiki instructions and created a "dovecot-acl" file within Public_Folders containing: owner lrwstiekxa user=user1(a)domain.com lrwstiek However this doesn't appear to do anything. All users can still access Public_Folders so I have a couple of questions that hopefully someone can help me with... 1) Is it possible to use the dovecot's ACL plug-in on a Public name space? 2) Is it possible to create dovecot-acl files with virtual usernames, i.e. user1(a)domain.com or does it have to be actual users, i.e. vmail? 3) Is it possible to restrict access within the namespace definition, i.e. set up another public namespace restricted to manager(a)domain.com? 4) Is ACL accepts & denies logged somewhere other than /var/log/maillog (my default)? 4) Is anyone successfully set-up an environment with a public namespace and ACLs? Any help would be greatly appreciated. Gavin

[Dovecot] making Dovecot match Courier POP3 UID's
by Jeff Tucker 20 Jul '06

20 Jul '06

Hi, guys. I've read the information in the Wiki about making dovecot's UID's match Courier's UID's in the POP3 server, so that a UIDL command on either server will return the same UID's for the same group of messages. However, what I've read doesn't match what I'm seeing in Courier. Courier appears to keep the UID numbers for messages that it uses for the POP3 server separate from the UID numbers for the IMAP server. Courier has a file: courierpop3dsizelist which has a line for every message, like: 1129610881.6075832619.blade4:2,S 2361 1478:1065670602 1129727025.1168007000.blade1:2,S 14718 1479:1065670602 1130005953.3295720403.blade5:2,S 1554 1481:1065670602 1130108068.0849623942.blade5:2,S 8246 1482:1065670602 The first column is the maildir filename, the last column is the UID that the POP3 server uses and the UID validity. Both are used to create the UID number returned by UIDL. The IMAP server uses a completely different UID number that's stored in courierimapuiddb. So, it seems to me that dovecot can't ever match Courier's UID numbers for the POP3 server unless it reads and interprets this courierpop3dsizelist file. My Courier-IMAP installation is Courier-IMAP 4.0.6. Any ideas? This is a real hassle because it means I can't switch the POP3 server from Courier to Dovecot or, if I do, lots of my users will download every message again which is just unacceptable. Thanks Jeff

[Dovecot] Getting maildir++ quotas working
by Bill Boebel 18 Jul '06

18 Jul '06

Can somebody post details for how to get maildir++ quotas working in the latest CVS? I have tried but can't get the CAPABILITY string to show "QUOTA"; and the GETQUOTAROOT command is recognized, but returns nothing... 2 GETQUOTAROOT INBOX * QUOTAROOT "INBOX" "" * QUOTA "" () 2 OK Getquotaroot completed. These are the settings I have... am I missing something? protocol imap { mail_plugins = imap_quota quota mail_plugin_dir = /usr/lib/dovecot/imap } plugin { quota = maildir imap_quota = maildir } Here are some more details: Dovecot is creating the maildirsize file in my maidir, and it seems to show correct storage used calculations, but the first line which should contain my storage limits is blank. So I suspect that I am not returning a valid quota value from the user database. I am returning what my old Courier-IMAP wants to see "1073741824S,4000C"... if the format for Dovecot is different, what should the format be? So there are two problems that I am trying to resolve, but I'm not sure how to go about fixing it. Any help would be greatly appreciated: (1) Dovecot isn't announcing QUOTA support in the capability string. (2) Dovecot isn't getting a valid quota limit, which I assume is breaking the GETQUOTAROOT command. Thanks, Bill

[Dovecot] Group-based filesystem quota
by Scott Alter 11 Jul '06

11 Jul '06

Hello. After using Dovecot for over a year, I have just started experimenting with the filesystem quotas, and I have a suggestion for improvement. On my mail server, I use group-based quotas, and would like to have Dovecot be able to report these quotas. It should be simple to implement, requiring only changes to the quota-fs.c file of the quota plugin. Simply changing USRQUOTA to GRPQUOTA should do the trick. In terms of the configuration file, "quota = fs" could be expanded to something like: quota = fs:storage=group # use filesystem quota with group storage limit Adding in support for message (inode) limits is just as easy, replacing dqb_curblocks with dqb_curinodes and dqb_bsoftlimit with dqb_isoftlimit. It could be easy to configure too, like: quota = fs:storage=group:messages=user # use filesystem quota with group storage limit and user messages limit Although I think I know what would need to be changed, I'm not a C programmer and my code would not be clean nor efficient. Since the messages and storage parameters of the quota setting are defined elsewhere (quota-maildir.c), I don't think it would be too difficult to duplicate this in the quota-fs.c file. Also, I am having the same problem as others with used space off by a factor of 4096, total limit off by a factor of 4. Stian's patch (http://dovecot.org/list/dovecot/2006-June/014159.html) does the trick, but I'm wondering if everyone is having this problem, or just those running Linux. Thanks, Scott

[Dovecot] subscription to mail folders not working properly anymore with dovecot1.0x ?
by Alain Hofer 04 Jul '06

04 Jul '06

Hi we run dovecot on sun solaris 9. I try to switch from dovecot 0.99.11 to dovecot 1.0, with ssl support turned on. The user's mail are stored in mbox format in Mail in their home dirs. I was not able to get the subscrition working properly with the new dovecot. New means: 1.0beta2 and now also 1.0.RC1 (beta9) The client mailreaders are mainly thunderbird 1.0x and 1.5.x, Netscape Messenger, and SquirrelMail for web access. The mail folder subscriptions stored in <usershome>/Mail/.subscriptions works fine with the dovecot 0.99.11. With dovecot_1.0 the subscriptions get properly read, but as soon as the user wants to make any changes to them (for example subscribing to a new folder out of thunderbird), the subscriptions get lost, the file <usershome>/Mail/.subscriptions simply disappears. Did I miss any point in the configuration? Or does someone else encounter the same problem?
