[Dovecot] Some of my IMAP Folders vanished in some MUAs
Hi, I'm using dovecot for some time now. Previously I was using Courier and I've migrated this setup to dovecot which went pretty fine. Now I'm experiencing some strange behaviour when using some newer mail clients. Some of my Folders, like spam, are vanished. The strange point is that it only happens in some clients, like Thunderbird 2.x+ or KMail 3.5.x. In others, like Thunderbird 2, Mutt or my Webmailer (Horde) they still show up. These folders are still there, i.e. in the filesystem, and the permissions seem to match those of the other folders which can be seem in all MUAs. I don't know if this is even related to dovecot but I think this is where I should start looking for an solution. I'm using dovecot 1.0.rc15 from Debian (stable/etch). It'd be great if anyone was able to help me. Thanks in advance. Best Regrads Dominik Schulz

Hi, it may be a susbscription problem, with the old clients showing all the folders and the new ones showing only the subscribed ones. See if you can subscribe to the missing folders, or change the default setting to show all folders. Aagur.

The autoheader step takes config.h.in and builds config.h, which then includes the HAVE_RQUOTA definition. Compiling your source then works. Aside: Can someone confirm whether I'm running these three utilities in the correct order? Once you get the code included you may find that, like I did, the code compiles but refuses to run. I'll try and work out a patch to the Makefile to build the xdr file that needs including (but, as I said before, I've never used the GNU autoconf stuff before so forgive me if I get it wrong!).

[Dovecot] vfile ACL's
(Sorry for the impatience. This was one of several questions in my email from yesterday. I thought I might have better luck being more direct.) Is there a way to set ACL's, using the vfile backend, on a truly global basis? or hierarchically (i.e. .Maildir.Sub inherits from .Maildir)? The wiki page says: The default ACLs for mailboxes is to give owner all permissions and other users none. Mailboxes in public namespaces don't have owners, so by default no-one can access them. Is this configurable? Thanks, Ben

Re: [Dovecot] Userdb and home directories (clarification)

At the moment the first of the two filers is not accessible to my Dovecot system and I assumed all would be well because, as far as I knew, I wasn't using it at all. We have two NetApp filers. One serves people's real home directories, and the other is serving the mailstore. The mailstore comprises two separate areas: one with quotas to store the messages in Maildir format; the second without quotas to store the control files for each user. The general format of these are: Message store: /mailstore/messages/letter/username Control files: /mailstore/control/letter/username where letter is the first character of the username We want the mail service to operate as a black box, with all necessary files stored on its filer. In particular we do not want anything storing within someone's home directory, and want the mail service to continue if the filer service home directories is unavailable. I am using passdb shadow and userdb passwd to authenticate and get users' details. These are being read from NIS, with each user having their own uid and gid. Because it is the general NIS map its home directory field specifies the user's real home directory on the other filer. Because I don't use %h anywhere in Dovecot's configuration I had assumed it did not use the home directory at all, and hence is independent of the other filer. However this morning's issue has shown this is not the case... As things stand Dovecot is using chdir() to move to the user's home directory, apparently in the early setup after logging in. As the home directories are currently unavailable to my test Dovecot service, giving a Permission denied error, Dovecot is aborting the session and so I'm not able to read mail. We can't have this for our production service so I'm trying to find out how to make things truly independent of the other (home directories) filer. I've read in the Wiki that it's best to set up a home directory for users and will be happy to have this as a subdirectory below the control files' directory. For example /mailstore/control/p/pmb1/home/... However I can't find a way of telling Dovecot NOT to use the home directory returned from the userdb passwd lookup, and instead use the above. I know setting the home directory is possible from userdb static, but we don't want everyone to use a single uid/gid: we want them each to use their own uids and gids so the filestore-based quotas work. Can someone guide me in this please? Either how to override the home directory setting, or an alternative way of configuring things to give the black box environment we are after?

Do you think it's a good solution to use one synchronised local Openldap on each server Dovecot ? No. I'd replicate your ldap database on a few servers that are dedicated to that purpose, and on each mail server use Dovecot's auth_cach feature to minimize how often it needs to query ldap. Do you think It's possible to use Postgresql or MySQL instead of Openldap ? We use MySQL. MySQL handles frequent writes better than OpenLDAP from our experience. It is also simpler for us to do replication and troubleshooting because we employ several MysQL gurus already. Are cyrus or courrier-imap better solutions ? Definitely not courier-imap, because of it's lack of indexes. Not sure about Cyrus. Someone say Zimbra is highly scalable and fast, I think Zimbra could be to heavy in this architecture, is Dovecot scalable ? My opinion is Zimbra is too heavy beccause of the way mail is stored on the backend. Dovecot with maildir scales out well, and the promise of dbox mail storage format appears that it will make it even more scalable down the road. Bill

[Dovecot] Userdb and home directories
Greetings - I've just discovered an oddity I didn't know I had... We have two NetApp filers: one serves people's home directories; the other their message store and control files filestores. At the moment the first of the two filers is not accessible to my Dovecot system and I assumed all would be well because, as far as I knew, I wasn't using it at all. However in practice Dovecot DOES appear to be using it: it is trying to chdir() to my home directory when I login, finds it can't at the moment (because of a problem giving Permission denied), and closes the connection. I've read the pages on home directories and the userdb on the Wiki and it advises that having a home directory is beneficial. I'm happy to create a subdirectory for this within a user's control files directory, but do NOT want it on our normal filestore: we can't have mail inaccessible because a user's home directory is inaccessible because the other filer is out of action. We use shadow for the passdb and passwd for the userdb (see dovecot - n output below). I'm trying to work out how to override the home directory returned from NIS. Ultimately I'd like to use this template: /mailstore/control/%1Ln/%Ln/home but for the time being while I'm trying to work out how to do it have my own area hard-coded in (as it's only me logging in to the test system): /mailstore/control/p/pmb1/home I'm specifying this with the args directive in the userdb section as follows: args = home=/mailstore/control/p/pmb1/home but it isn't being picked up.

Hi Timo,
I just tried your patch in hg and realised it also requires the
Content-Transfer-Encoding: 8bit to be present.
I'm seeing some really bad mailers at my site that provide just header
Content-Type: text/html; charset=iso-8859-1 :(
Is there a possibility for us to accommodate such mails as MIME?
Well, I'm not sure how you'd want Dovecot to handle it. All of this
basically only changes BODY and BODYSTRUCTURE replies. With
Content-Type: header Dovecot returns its contents, but a missing
Content-Transfer-Encoding: causes it to use 7bit as default:
* 1 FETCH (BODY (text plain (charset iso-8859-1 format
flowed) NIL NIL 7bit 623 22))
So are you saying that you'd want it to use 8bit as default?
Although if your Content-Type really has quotes around charset, that's
the problem. It's completely broken then and Dovecot just ignores it:
* 1 FETCH (BODY (text plain (charset us-ascii) NIL NIL 7bit
623 22))
UW-IMAP handles it a bit differently:
* 1 FETCH (BODY (TEXT PLAIN ({20}
CHARSET=ISO-8859-1 MISSING_PARAMETER_VALUE FORMAT flowed) NIL
NIL 7BIT 623 22))
Hi Timo,
Thanks for the explaination. I think the bad e-mail header I received was
not too good. The patch applied is OK.
Cheers.
Re: [Dovecot] Some of my IMAP Folders vanished in some MUAs
Please don't top-post... :) Uhm, ok. That's a no-go these days? It always makes list discussion difficult to read... bottom posting and snipping irrelevant material makes for clean, simple, intelligible threads. Eh? Folder subscription is such a basic feature/function of IMAP that I would not blame the MUA in this case, I'd blame the user... ;) Yes, ok. Thats probably the case. I, as the administrator, should have known better, but I don't expect my end-users to know anything about IMAP at all. They just get the credentials to enter into their MUAs and shouldn't have to worry about anything else. Well, since I've never met a mail client that completely configures itself, you have to make up for this with, complete, clear and concise written user instructions... then be prepared to deal with the ones who will simply refuse to read and/or comprehend what you took such pains to write up for them. This is not what I call user-friendly. Do you have a better way of managing folder subscriptions? As history has shown, Timo is very open to innovating in dovecot... No, I don't. Please don't get me wrong. I very happy with dovecot. It's exactly as I expect it to be. I was just confused by the way different versions of, e.g. Thunderbird, handle subscriptions. Understandable... but as you pointed out, that isn't a dovecot issue/problem... ;) And I hope you weren't offended by my short/to the point reply - none was intended... -- Best regards, Charles
[Dovecot] Password Encryption
Hi all. I hope this is not a RTFM-type question, but I've been unable to find a searchable archive of this mailing list... I recently began investigating using Dovecot/Postfix/MySQL solution. I've been following the documentation http://wiki.dovecot.org/HowTo/DovecotLDAPostfixAdminMySQL?highlight=%28m ysql%29 While everything seems to have gone right, I have been unable to successfully login to the IMAP server using Outlook Express. It seems that the problem may relate to PostfixAdmin storing passwords in the mysql database md5 encrypted, and Dovecot is not able to read them, but I am not certain. The error when a client logs in is something like dovecot: auth-worker(default): plain_md5_verify([EMAIL PROTECTED]): Invalid password encoding David Morrow Technical Systems Lead Autodata Solutions Company [EMAIL PROTECTED] mailto:[EMAIL PROTECTED] http://www.autodatasolutions.com http://www.autodatasolutions.com/ Tel: (519) 963-3020 Fax: (519) 451-6615 Think slowly.

[Dovecot] modify header in deliver
hi, is it possible to modify the mail-header (subject) within the deliver process (maybe by a lda-plugin)? I have tried to write a simple plugin for this, but I cannot find a way to modify the mail befor writing it to the mailbox.

Re: [Dovecot] Dovecot strong or not for a big Webmail architecture

No. I'd replicate your ldap database on a few servers that are dedicated to that purpose, and on each mail server use Dovecot's auth_cach feature to minimize how often it needs to query ldap. A few OpenLDAP servers should be able to cope with the load easily. We're using 3 OpenLDAP servers for 1.000.000 mailboxes and they're mostly idle. Just make sure you setup the right indexes. Do you think It's possible to use Postgresql or MySQL instead of Openldap ? We use MySQL. MySQL handles frequent writes better than OpenLDAP from our experience. It is also simpler for us to do replication and troubleshooting because we employ several MysQL gurus already. Provisioning data usually is not written frequently, but read continously. This is where LDAP works better. And read-only replication is easy enough with OpenLDAP. Geert
