[Dovecot] Dovecot 1.0.15, sieve fileinto subdirectory ?
by Karel Hendrych 26 May '09

26 May '09

Hi, does sieve plugin in 1.0.15 support fileinto subdirectory? There is a maildir .oss.dovecot and sieve rule: if envelope :contains "to" "k+dovecot" { fileinto "oss.dovecot"; } But I get LDA error: Couldn't open mailbox dovecot: Mailbox doesn't exist: dovecot Any suggestions? Delivery to non-subdirectories is working fine. Regards -- Karel

[Dovecot] libsieve problems / wishes
by Steffen Kaiser 26 May '09

26 May '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I'm trying libsieve (853:42e154b8792e) to cope with our current installation, the following issues arise: 1) vacation addresses are compared case-sensitivly, e.g.: vacation :addresses [ "Steffen.Kaiser(a)example.com" ] ""; it won't match "steffen.kaiser@...". attached patch makes a first shot about that problem, leaving: 1a) maybe one should lower-case :addresses argument at compile time and my_address at run-time and then use strcmp() again. 1b) duplicate checks are case-sensitive, too. This is probably no big issue, because if the same person uses different variants of his/her mail address for sending, s/he does not deserve better. 1c) Suppression of replies to own mails are case-sensitive, too. Well, many people I know test that "it just works" by sending themselves a mail. I would disable this check. 2) we have about 157 ways to write the domain part. Not all accounts are available in all of them, but it's close to it. The old vacation program we used prior to "cmusieve" didn't care about the domain unless explicitly given. It was quite painful. Attached patch adds a "domainless" variant of :addresses arguments in such way, that vacation :addresses [ "Steffen.Kaiser" ] ""; matches any domain. Ideally, it would be better to specify all valid domains, but perhaps one can leave that for another approach with a different syntax, e.g. with "@*" as domain? Maybe, there is a better approach. Now there is possibility that common local parts are matched from alien domains easily. If to specify a set of "default" domains would be an option for libsieve, what is the suggested way: - - as user-option via dovecot.conf? - - as admin-enforced Sieve-script that sets some internal variables? aka using the multi-script capability - - ??? 3) Because I try to migrate from cmusieve v1.0, I have a name issue with "imapflags". README sec "* Supports all extensions provided by the original CMUSieve plugin:" and sec "Implementation Status" explains that "imapflags" is available. This is not true entirly: "imapflags" is not, lib-sieve uses the name "imap4flags" as defined by RFC. So, it leaves me with two options: 3a) convert all user scripts and hack Horde-Ingo, or 3b) have libsieve accept the alias "imapflags" for the extension "imap4flags". Would it be worhtwhile for libsieve to implement aliases for extensions, so that they are available in require by more than one name? About Horde-Ingo, maybe they have an update to use "imap4flags", too, but it looks like that I upgrade Dovecot before Horde.

[Dovecot] Maildir with LAYOUT=fs not working
by Rich Wales 26 May '09

26 May '09

I'm considering converting a Cyrus system (managing my family's e-mail) to Dovecot. I'm trying Dovecot 1.1.15 on an Ubuntu 9.04 (2.6.28-11-server) system. My production server is currently running Cyrus 2.3.14. Since I have a huge number of folders and subfolders, I need to use LAYOUT=fs. However, it's not working consistently. I tried setting up a test account in Thunderbird (2.0.0.21), and I was able to create folders under the Inbox, and they showed up as nested subdirectories under my ~/Maildir on my mail server. So far, so good. However, when I tried a home-grown Perl script (an archival scheme for my work e-mail), Dovecot wouldn't create subfolders properly; instead of nesting them (as I thought LAYOUT=fs would do), it used a flat layout. Here is a trace (generated by my Perl script) of an IMAP session. This was supposed to log in as the user "stanford" (the name of my archival account); create a folder named "2009" if not already present; create (again, if not already there) a "2009-05" folder inside the "2009" folder; and, finally, save a message (marked as seen) inside the "2009-05" folder. 1 LOGIN XXXXXXXX XXXXXXXX1 OK Logged in. 2 STATUS user.stanford.2009 (MESSAGES)* STATUS "user.stanford.2009" (MESSAGES 0) 2 OK Status completed. 3 STATUS user.stanford.2009.2009-05 (MESSAGES)* STATUS "user.stanford.2009.2009-05" (MESSAGES 3) 3 OK Status completed. 4 APPEND user.stanford.2009.2009-05 (\Seen) {4043} + OK (message text here . . .) 4 OK [APPENDUID 1243306507 4] Append completed. 5 LOGOUT* BYE Logging out The above works perfectly when I'm talking to my Cyrus server. However, when I tried the same thing with Dovecot, I got a folder named "user.stanford.2009" in the "stanford" account's Maildir, and then another folder named "user.stanford.2009.2009-05" (again, in the Maildir -- NOT nested in the "user.stanford.2009" folder) -- and the message was stored in the "user.stanford.2009.2009-05" folder. I tried changing my Perl script to use "INBOX" instead of "user.stanford" -- but the result was basically the same, except I got new folders named "INBOX.2009" and "INBOX.2009.2009-05" directly in my archival account's Maildir. Finally, I tried omitting any prefix at all on the folder names, and I got new folders named "2009" and "2009.2009-05" -- again, directly in Maildir -- no nesting of one folder within another. I suppose I actually have two issues here -- the lack of folder nesting (even with LAYOUT=fs), and also Dovecot's failure to recognize a "user.XXX." prefix on a mailbox name as designating user XXX's inbox (something that seems to work fine on Cyrus). My Cyrus server currently has over 1,600 folders and subfolders, so I absolutely can't / won't consider switching it to Dovecot unless I can get the nested filesystem layout working. Any thoughts? -- Rich Wales / richw(a)richw.org / richw(a)stanford.edu Wikipedia: http://en.wikipedia.org/wiki/User:Richwales Facebook: http://www.new.facebook.com/profile.php?id=206680

[Dovecot] lda deliver per instance sieve configuration
by J.P. Trosclair 26 May '09

26 May '09

I'd like to override the sieve settings in dovecot.conf for a deliver instance that is being run from a custom archiving script. This is dovecot 1.0.15 on debian lenny. Is this possible? Doesn't appear to be looking through the WIKI. If it's not any suggestions? The problem is the user specific sieve scripts override where the archived mail is supposed to be stored (maildir:~/.Archives.YYYY-MM) so I'd like to disable their sieve scripts while the archived mail delivery via deliver is taking place. Thanks, J.P.

[Dovecot] Separate home and mail folders problem on delivery
by Николай Бочев 26 May '09

26 May '09

Hello, I am using dovecot 1.2rc series on my mail server combined with postfix ( virtual users with postgre ). I have setup separate home and mail locations. It works fine ( with sieve etc. ). The user home folders are in /home/vmail/%d/%n and mailboxes are in /srv/mail/%d/%n . The permissions are fine and everything is working except in the following case : If a user does not have a home dir already crated ( the home dirs get auto created when creating a sieve script through managesieve for example ), and he recieves a message with an attachment, the delivery fails with the following error : May 19 10:47:28 mail postfix/pipe[2759]: 969531007B: to=<office(a)grandstarco.com>, relay=dovecot, delay=2296, delays=2296/0.2/0/0.06, dsn=4.3.0, status=deferred (temporary failure) The Dovecot deliver log says : > 2009-05-19 10:47:28 deliver(office(a)grandstarco.com): Error: creat(/home/vmail/grandstarco.com/office/.temp.mail.dodo.bg.2760.1242719248… failed: No such file or directory > 2009-05-19 10:47:28 deliver(office(a)grandstarco.com): Error: copy: i_stream_read() failed: No such file or directory > 2009-05-19 10:47:28 deliver(office(a)grandstarco.com): Error: sieve: msgid=<1242716935.24056.6.camel(a)shiny.bgservice.local>: failed to store into mailbox 'INBOX': Internal error occurred.

[Dovecot] convert-tool skip_dotfiles is not the actual option
by Kenneth Porter 26 May '09

26 May '09

Looking at the source for convert-tool.c, I see this: "Usage: <username> <home dir> <source mail env> <dest mail env>\n" \ " [skip_broken_mailboxes] [skip_dotfiles] [alt_hierarchy_char=<c>]" else if (strcmp(argv[i], "skip_dotdirs") != 0) set.skip_dotdirs = TRUE; Looks like the usage line needs to be fixed (dovecot-1.2-0.rc2).
