[Dovecot] INTERNALDATE call, timezone randomly changes
by Guy 30 Nov '08

30 Nov '08

Hi guys, I've run into an odd little problem. We use SquirrelMail as the basis for our webmail. Recently I've had a user complaining that the "Received" time on mail in the Sent folder has changed between logins. The change is always been by +1 hours or -5 hours. While checking, our developer had a time changed by +2 hours. On refresh it changed back. He poked through the code and it looks like SquirrelMail gets the received date via an IMAP command: A003 FETCH 1:10 (INTERNALDATE FLAGS BODY.PEEK[HEADER.FIELDS (To Content-Type Subject Date)]) I'm running dovecot 1.1.6, and I'm wondering how that function gets the date and time? If I can isolate the source of the timezone I can try and correct it. The server time shown by "date" is correct and /etc/localtime is /usr/share/zoneinfo/Europe/London (which is correct - I've also se the timezone in /etc/conf.d/clock is set to "Europe/London" now), so I'm wondering where else the information could be coming from? Thanks for any information you can give me to help isolate the problem. Guy -- Don't just do something...sit there!

[Dovecot] v1.2.alpha4 released
by Timo Sirainen 30 Nov '08

30 Nov '08

http://dovecot.org/releases/1.2/alpha/dovecot-1.2.alpha4.tar.gz http://dovecot.org/releases/1.2/alpha/dovecot-1.2.alpha4.tar.gz.sig Note that there are significant changes in this release from alpha3 and I haven't tested everything extensively. Be careful. The next release will hopefully be v1.2.beta1 with a feature freeze. Most importantly shared mailboxes and IMAP ACLs are finally supported. This is mainly thanks to the Kolab people (looks like I forgot your names from NEWS file, the next release will have them). I'll have to write a wiki page about ACLs, but the main thing you need to know is that if you want shared mailboxes to be LISTable by other users, you'll need to specify acl_dict. If you don't expect many shared mailboxes, a file backend is the easiest, but you could also use SQL or Berkeley DB. With a file backend you could also create per-domain files, which will improve performance if you don't need cross-domain shared mailboxes. You could do this with e.g.: acl_file = /home/virtual/%d/shared-mailboxes Also full text searching works now better with virtual mailboxes. Previously the fts would have duplicated the indexes for virtual mailboxes. Now with Solr backend it searches the original mailboxes directly. Although this is still missing some optimizations and also it doesn't check first if mails are missing from the original mailboxes, so it may not find everything. Also this still doesn't work with Squat backend.. Anyway, a bit more code and Dovecot will have fast full text searching from all mailboxes (virtual * mailbox). I implemented also draft-gulbrandsen-imap-response-codes-04, which adds some [codes] for all IMAP command failures, which should make it possible for clients to figure out more easily what caused the failure. Hopefully the draft won't change much anymore. :)

[Dovecot] Dovecot as proxy for M$ Exchange mailboxes
by Axel Schmalowsky 30 Nov '08

30 Nov '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi list, is there a way to use dovecot as proxy for m$ exchange mailboxes? Currently, our clients not only can login to their mailboxes with their e-mail address but also with their accountid. Both the clients e-mail address and accountid are stored in ldap. Now I need a way to let dovecot rewriting the client's accountid to the respective e-mail address. Is this possible with the proxy-feature of dovecot? Any hints would be appreciated. - -- Freundliche Grüße / Kind regards Axel Schmalowsky Platform Engineer ___________________________________ domainfactory GmbH Oskar-Messter-Str. 33 85737 Ismaning Germany Telefon: +49 (0)89 / 55266-356 Telefax: +49 (0)89 / 55266-222 E-Mail: aschmalowsky(a)df.eu Internet: www.df.eu Registergericht: Amtsgericht München HRB 150294, Geschäftsführer Tobias Marburg, Jochen Tuchbreiter -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFJL+JKsuqpduCyZM0RAoFUAJ9mPbv5eI5xP54YhwlmOs40F1RxDQCgir5l jCdaNeXKO8FnOCxaKSI7S4E= =m5WN -----END PGP SIGNATURE-----

Re: [Dovecot] Dovecot - Vpopmail subdirectories
by Yacoubi Mohamed 28 Nov '08

Hello, Thank you for this link, but this is not what I want. Dovecot is only used for imap. Currently, authentication works fine, but new fields are created in a subdirectory. Example: /var/vpopmail/domains/0/domain.com Once authenticated, I just want to be in chroot /var/vpopmail/domains/0/domain.com/user and not in /var/vpopmail/domains/domain.com/user I explained that vpopmail which manages the creation of areas and I can not influence the subdirectory. Sincerely, -- Mohamed YACOUBI

[Dovecot] ManageSieve and invalid scriptname
by Miguel Filho 28 Nov '08

28 Nov '08

Hello there, I have been using pysieved and avelsieve and it has been working great. I decided to do test with the ManageSieve patch and got this problem: Nov 27 17:21:29 cambui dovecot: MANAGESIEVE(miguel): sieve-storage: using active sieve script path: ~/.dovecot.sieve Nov 27 17:21:29 cambui dovecot: MANAGESIEVE(miguel): sieve-storage: using sieve script storage directory: ~/.sieve Nov 27 17:21:29 cambui dovecot: MANAGESIEVE(miguel): sieve-storage: relative path to sieve storage in active link: .sieve/ Nov 27 17:21:29 cambui dovecot: MANAGESIEVE(miguel): sieve-storage: Active sieve script symlink /home/admsis/miguel/.dovecot.sieve is broken: invalid scriptname (points to .sieve/phpscript). Well as you can see, a file without the .sieve is not welcome :-( I checked the RFC and there is no requirement for a .sieve file extension when considering scriptnames. http://tools.ietf.org/html/draft-martin-managesieve-12#section-1.6 Is this a misplaced restriction or it really should be enforced for any reason? I hope that this can be tolerable, or I will have to rename a lot of scripts and remove all hardcoded "phpscript" strings from avelsieve :-( Regards and thanks for the great work. Miguel

[Dovecot] Sieve and global scripts
by Allan Cassaro 28 Nov '08

28 Nov '08

Hi Stephan Bosch, there's any way to make the dovecot deliver agent (with sieve) load a "global sieve script" before load the user sieve file? I want to create some rules for every one, like: "if header contais: IS SPAM, move to SPAM BOX"... I made this today with a couple of "sed + awk" and a wraper for managesieve-login... but, this is definily not the best way to do this... This is possible to do? (Even with change in the code) Regards. -- "Não deixe a faculdade atrapalhar seus estudos." http://allan.cassaro.googlepages.com

Do i need to give dovecot a > message number that was last downloaded? If the UIDLs are exactly the same, I've no idea why the client would download a duplicate. I haven't heard before that a changed IP would be an issue. Of course that would still be a client-specific issue. Sounds a bit unlikely though. Ccing back to list in case someone else has an idea..

[Dovecot] Namespaces and shared folders
by bbell2000 28 Nov '08

28 Nov '08

I had a working dovecot install before I tried to implement shared folders using namespaces. I added the following to /etc/dovecot/dovecot.conf: namespace private { separator = prefix = inbox = yes } namespace public { separator = / prefix = location = maildir:/home/public/shared/Maildir } </pre> I created my shared folder using the maildirmake command that came with qmail: maildirmake -S /home/public/shared/Maildir maildirmake -s write -f online /home/public/shared/Maildir chown -R dovecot:shared /home/public/shared find /home/public/shared -type d -exec chmod 0777 {} \; find /home/public/shared -type f -exec chmod 0666 {} \; At this point, the online folder shows up as a subscribable folder in Thunderbird. I can subscribe to online and I can still access my Inbox. But I can't get to any of the folders in my Inbox (Trash, Drafts, etc.). I can access these folders if I comment out the namespaces and revert to the default behavior. There are no clues in mail.err, mail.info or mail.warn -- the only messages are the ones written when my client establishes a successful IMAP connection. What did I do wrong? -- View this message in context: http://www.nabble.com/Namespaces-and-shared-folders-tp20727713p20727713.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] UIDL question
by Wouter van der Schagt 28 Nov '08

28 Nov '08

Hi all, I'm migrating a Postfix + Dovecot 1.0 server with mboxes to Qmail + Dovecot 1.4 with Maildirs and encounter the following the problem. Using perfect-maildir.pl from: http://perfectmaildir.home-dn.net/ i can relatively succesfully convert the mbox to a Maildir. The problem, however is that clients with "leave mail on server" set to on retrieve all email a 2nd time. I understand this must be because the email client "sees" a different UIDL and downloads the message again. Looking at the 1.0 configuration, i do not see a "pop3_uidl_format" setting. So was wondering how the UIDL is generated. Is anybody aware of a conversion script that properly maintains the UIDL? Or am I misisng something else here? Sincerely, - Wouter van der Schagt
