[Dovecot] public folders aren't public
by Mark Nienberg 30 May '06

30 May '06

I'm testing dovecot as a replacement for an aging UW-IMAP server. I have the basic IMAP setup working but I'm stuck on public folders (which my users are addicted to). I set up public folders generally a described in the wiki. The problem is that when a user creates a new public folder, the folder is owned by the user with permissions drwx------ which prevents other users from viewing the contents. Here is part of dovecot.conf: namespace public { separator = / prefix = Public/ location = maildir:/home/public/Maildir } and here is the Maildir directory [root@tesla Maildir]# ls -la total 70k drwxrwxrwx 7 dovecot Everyone 4.1k May 12 14:33 ./ drwxrwxrwx 3 root root 4.1k May 12 13:43 ../ drwxrwS--- 2 dovecot Everyone 4.1k May 12 13:48 cur/ drwx------ 5 david Everyone 4.1k May 12 14:33 .davi/ -rw-rw-r-- 1 dovecot Everyone 0 May 12 13:46 dovecot-shared drwxrwS--- 2 dovecot Everyone 4.1k May 12 13:48 new/ -rw------- 1 mark Everyone 6 May 12 14:07 subscriptions drwxrwS--- 2 dovecot Everyone 4.1k May 12 13:48 tmp/ drwx------ 5 mark Everyone 4.1k May 12 14:30 .tryit/ The directories .davi/ and .tryit/ were created by users david and mark respectively. These are real system users. They are both members of the Everyone group. Any suggestions appreciated. Thanks, Mark

[Dovecot] IMAP server <defunct> (beta 7)
by Graham Briggs 30 May '06

30 May '06

Hi, We've been using a 0.99 version of Dovecot for nearly a year without problems, but due to a server death I had to reinstall with the same configuration as before, but more recent versions of the software, on different hardware. This time though, every few days IMAP login and access fails, and the output of ps ax shows entries such as [imap-login] <defunct> and [imap] <defunct>, with the lovely brain-eating Zombie status. There is nothing in the log file that suggests an issue. We're using dovecot with authentication/etc being done against a Postgresql database. I searched online for a solution, but the nearest problem said it was a problem with PAM, which we are not using with Dovecot. We're using Maildir as the message storage format. Does anyone have any suggestions as to why this might be occurring? If it will help to see the dovecot configuration files then I can provide them. The platform is Debian 64-bit running on a dual-core Opteron system. Yes, it isn't Debian-stable! Graham

[Dovecot] Maildirquota
by Rodolfo Gonzalez Gonzalez 30 May '06

30 May '06

Hi, I'd like to use dovecot+postfix (with Maildir) for several virtual email servers, but one requirement is quota support. I'm aware about the lack of maildirquota support in dovecot, and I found a patch in the "unofficial patches" section which is said to provide maildirquota support to dovecot. How stable is this patch?, is it usable with dovecot 1.0b2?. And, is there any plan to support maildirquota natively in the near future?, I'd like to replace courier-imap in my setup. Thanks. Rodolfo.

[Dovecot] Problems with subfolders in Thunderbird
by Ian Thurlbeck 30 May '06

30 May '06

Dear All Server: dovecot-1.0.beta8 (compiled from source) centos 4.3 Client: thunderbird 1.0.8 on Fedora Core 4 on port 993 Using maildir Normally (with the current UW-IMAP) I can create a folder which may contain only messages or only folders. If I create a folder which will contain only folders, it is listed in thunderbird in light-grey italics. Subsequently I can create message folders within this folder. When doing the same thing using dovecot as the server, the same options are available, but any attempt to create a folder containing only folders is silently ignored and nothing happens (nothing is created anywhere on the server filesystem). Is this a known problem ? I do not want to use the setting which allows you to create folders which may contain both messages and folders.

[Dovecot] Hint for Fatal: sigaction(SIGRTMIN) failed: Invalid argument
by Breno Jacinto Duarte da Costa 30 May '06

30 May '06

Hello, Search google I've found a thread ("errors in logfile") discussing a similar problem to mine. It`s something related to the #define IOLOOP_NOTIFY_DNOTIFY in config.h, but disbling it resulted in errors in compilation. I'm really running out of answers for this one... if anyone could give a hint, it'd be of great help. cheers -- .''`. -- Breno Jacinto : :´` : -- breno /at/ freeunix dot com dot br : ' ' : -- 88AE 3F43 7110 57F6 A206 `. `'` -- D116 02CA 02F4 803D 4294 `-- -- Debian GNU/Linux - The Universal OS

[Dovecot] imap proxy and passwd-like passdb/userdb
by HenkJan Wolthuis 30 May '06

30 May '06

Hi, I'm testing/using dovecot as imap proxy, passdb/userdb as passwd-like-file. It seems to function as expected (1). This setup is described in the wiki in AuthSpecials. But I also noticed in the documentation (ImapProxy / FeatLoginProxy pages) that the proxy feature only works with a sql passdb. Maybe I did something strange, but passwd-like-passdb does work..... So I have some questions: Is the documentation wrong? Is the documentation right? ;-) Are there reasons not to use dovecot this way (other than scalability / maintainability)? Are there bugs I've not yet seen? (am I the only one using dovecot this way?) thanks-in-advance, HenkJan 1) i'm proxying to a courier backend, had to modify dovecots capability_string, because the emailclient gets the capabilities from dovecot, while it uses the proxied server (=courier). Had some strange errors with append, as courier doesn't support Literal+, modifying dovecot so that it stopped advertising Literal+ solved the problem....

[Dovecot] Out of Quota Causing "BYE Too many invalid IMAP commands."
by Timothy White 30 May '06

30 May '06

Doing some testing in Squirrelmail, with quotas, and basically opening a message, and saving it as a draft, over and over until I run at of quota. This is what I get when I try and save a message that is larger than the size left May 30 19:36:36 mafeking dovecot: IMAP(joeblogs): Disconnected: Too many invalid IMAP commands. and in SM ERROR: IMAP server closed the connection. Server responded:* BYE Too many invalid IMAP commands. I would expect something a little more user friendly in that situation. I haven't worked out how to debug the IMAP session in SM, or how to run an IMAP session with logging. I may get around to setting up debug in dovecot to see what happens. I'm running dovecot beta8. Any suggestions as to how to make it 'die' nicer? Thanks Tim -- Linux Counter user #273956

[Dovecot] Leave copy on server problem.
by Dario Ale 30 May '06

30 May '06

Hello, I am using Dovecot 0.99.14-r1 with mbox format. I have a problem with the option "Leave copy on server", the messages are duplicated. I tried many options but I can´t find the solution. The last test was: I modified in src/pop3/commands.c (function list_uids()) the folowing things: "... client_send_line(client, message == 0 ? "%u %u.%u" : "+OK %u %u.%u", mail->seq, client->uidvalidity, mail->uid); ..." by "... client_send_line(client, message == 0 ? "%u %08x%08x" : "+OK %u %08x%08x", mail->seq, mail->uid, client->uidvalidity); ..." then, I removed all index files so this were regenerated, I deleted popstate.dat, after with Mozilla Thunderbird I got the messages. popstate.dat was regenerated too, with the following information: this is the last lines: "... k 000000b14062ffdb 1148496134 k 000000b24062ffdb 1148496135 " After I send a new email and get messages, the last lines in popstate.dat was: "... k 000000b14062ffdb 1148496134 <-- no duplicated k 000000b34062ffdb 1148496827 <-- duplicated of k "000000b24062ffdb 1148496135" k 000000b44062ffdb 1148496828 <-- new " the new messaged arrived and the previous message was duplicated. This problem happens with OutLook Express too. Please, somebody can help me?? Thanks very much. pd: sorry by my english. -- Dario Ale (dario.a en telpin.com.ar)
