[Dovecot] imap default separator ignored?
by Harald Dunkel 03 Jan '10

03 Jan '10

Hi folks, I have configured the imap folder separator to '/' (see below). AFAIU the separator character does not affect the internal folder representation managed by Dovecot, but just the communication between client and imap server. Question is: What is supposed to happen if I try to create a folder named "a.b" in this configuration? Since '.' is not a separator character anymore, and since the client doesn't know anything about the internals of Dovecot, I do not see why Dovecot complains about an invalid character? Shouldn't it hide its internal Maildir structure?

[Dovecot] Problems getting the antispam-plugin to work
by Malte Schirmacher 03 Jan '10

03 Jan '10

Hi List, i'm running the current debian lenny dovecot-version (dpkg says it's 1.0.15-2.3+lenny1) and i'm trying to get the antispam-plugin ('1.2+20090702-1~bpo50+3') to work. Unfortunately dovecot always says "antispam plugin not configured" moving spam into the spam-folder. My config: protocol imap { mail_plugins = antispam } plugin { antispam_signature = X-DSPAM-Signature antispam_signature_missing = error antispam_trash = Trash antispam_spam = Spam antispam_dspam_binary = /usr/bin/dspam antispam_dspam_args = --deliver=;--user;%u } Thanks in advance Malte Schirmacher

[Dovecot] What auth ?
by Spyros Tsiolis 03 Jan '10

03 Jan '10

Hello people, First of all a Happy New Year and best wishes to you all. I've managed to setup dovecot v1.2.9 on a CentOS 5.4 system and I am now, trying to make it auth. I would prefer virtual users and only want to make the IMAP/ IMAPS part work. I don't need POP3 or anything else. The rest will be handled by another SMTP/POP3 application. Now, I almost managed to make dovecot auth a virtual user with his password. However, when it seems it has passed the auth stage (either via IMAP _or_ IMAPS), the command line kicks me out. Here's roughly what I did : 1. Created /etc/dovecot/users and /etc/dovecot/passwd 2. filled in a couple of usernames/passwords encrypted in MD5 format 3. Ran dovecot from command line (service dovecot start [after I created the service ofcourse]) 4. telneted to localhost via port 143 or 993 (with the help of openssl: "openssl s_client -connect the.system.name:993") 5. typed : . login username@fqdn <password> Something worth noticing for step "5". If I do this logging-in with the "user@fqdn" format, the systems kicks me out. I, then, check the latest on "/var/log/dovecot/errors" to find that the system does not complain about the auth. If I do the same logging-in but instead use "user@localhost" (and not the fqdn), the system fails the authentication stage and does _not_ drop me into the shell. Go figure !! Anyway. My question, in essence, is this; Which type of auth should I use ? The manuals (that i've been sinking my head for the last couple of weeks) suggest I should use PAM. PAM, I cannot understand. At the moment, I _think_ I am using MD5. Any pointers here ? I've been reading the /doc/wiki directory for quite some time until it made no sense to me anymore (too much info makes me loose perspective). Any help would be greatly appreciated. TIA, spyros

[Dovecot] disable lazy_expunge for some mailboxes?
by Frank Cusack 03 Jan '10

03 Jan '10

How to disable lazy_expunge for certain mailboxes? My problem is I have a public namespace, whose mail is on a different filesystem than user mails. Some users are allowed to expunge on this shared mailbox, but lazy_expunge is stopping that from working since the mail has to cross a filesystem boundary to make it into the lazy_expunge namespace (location is under the user's home directory). As a workaround can I run a daily cron job to remove messages with the \Deleted flag on them? If so how do I find them? thanks -frank

[Dovecot] Recalculate quota usage on demand
by Michael 02 Jan '10

02 Jan '10

I would a method for Dovecot to recalculate the quota usage and rewrite it to the quota DB (Called on demand by a non-Dovecot POP3 daemon) I don't want the line deleted in the DB as this would only recalculate next time the Dovecot LDA or IMAP handles a message, and I want to keep the data availability contiguous. Can this be done?

[Dovecot] nested folders
by Jim Pazarena 02 Jan '10

02 Jan '10

using both thunderbird and roundcube with dovecot IMAP, I can create all the folders I desire, but cannot create subfolders; I also cannot delete a folder once created. I get a very un-informative error message from each. Is there a special setting required to permit sub-folder creation? folder deletion? I've got 770 mail:mail virtual_user_home 770 mail:mail mail_sub-directory 770 mail:mail .imap 660 mail:mail .subscriptions 700 mail:mail Drafts 700 mail:mail INBOX 700 mail:mail Junk 700 mail:mail Sent 700 mail:mail Trash Suggestions would be appreciated.

[Dovecot] Using Push IMAP to trigger POP3 download
by Aaron Whitehouse 02 Jan '10

02 Jan '10

Hello all, I have an HTPC connected 24/7 to the Internet running Mythbuntu. I also have a web/email host that runs Dovecot for email and provides IMAP and POP3 access. I understand that Dovecot supports Push IMAP and I could, for example, use Thunderbird to connect to my email host to receive instant email as it arrives. I would like to add a Dovecot IMAP server on my HTPC (for increased storage, to aggregate multiple email accounts, to process messages with SpamAssassin and to provide a better webmail interface) and retrieve email from my webhost to my HTPC by POP3. To set up POP3 on my HTPC, I understand that the norm is to set a time interval (say, every 10 minutes) for clearing email. What I would prefer to do, if possible, would be to have Dovecot on my HTPC keep a Push IMAP connection with Dovecot on my webhost. When a new message is available on the webhost, my HTPC would be "pushed" a notification and it could do a POP3 download. This would allow it to clear emails with POP3 (and reduce storage requirements on my webhost), mean that I received emails instantly and not require me to have it poll for messages on a very-regular basis. Does anybody know if this is possible? As an alternative (not solving my space problem on the webhost, but solving the others), is it possible to set up Dovecot to "piggy back" off an existing IMAP server? In my example, my webhost does not offer good spam-checking and webmail. Would it be possible for me to set up a Dovecot server on my HTPC that received messages by Push IMAP, processed them with SpamAssassin (say, moving all of the spam messages to a subfolder) and provided a good web interface, all the while providing updates to the webhost's server? In some ways, this is almost more like an IMAP client than a server. I apologise if these questions are stupid! Happy New Year and thanks in advance, Aaron -- FSF Associate Member: 5632 http://www.fsf.org

[Dovecot] Deliver virtual user's mail to a specific namespace?
by Brian Schang 02 Jan '10

02 Jan '10

Hello: I have virtual users set up for the various mailing lists that I subscribe to. Everything has been working well in both Postfix and Dovecot. Postfix is configured to deliver to a specific mbox file within my mbox mail root. I can access retrieve and read email via Dovecot without any issues. Now I want to make my setup more robust and have these messages delivered to a maildir namespace. I have configured the LDA within the Postfix master.cf file: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${recipient} I have configured the 'dovecot' transport within Postfix in the transport file: test(a)lists.schang.net dovecot: In dovecot.conf I have set up the namespace as follows: namespace private { separator = / prefix = "Lists/" location = maildir:~/MailLists subscriptions = yes } I'm having a hard time specifying the "Lists/" namespace in my userdb passwd-file: test:{PLAIN}linux:2000:200::/home/brian::userdb_mail=maildir:Lists/test I can't get the userdb_mail portion to work. For this user, 'test(a)lists.schang.net', how do I tell Dovecot/deliver to put the message in the 'test' mailbox within the 'Lists/' namespace? I'd appreciate any insight. Thank you. -- Brian Schang

[Dovecot] Issue Authenticating to a new dovecot-postfix installation
by Anthony Nedland 02 Jan '10

02 Jan '10

(Apologies if this is a resend, but I thought I had received a bounceback message.) I have installed dovecot-postfix and postfixadmin on an Ubuntu 9.10 machine. The userdb and passdb are both mysql. If I set up a user in postfixadmin they are able to send. I can successfully telnet into the server remotely by name on 110 and 25. I'm not looking for any authentication encryption/ssl any of that, just POP3/SMTP. When I telnet into 110 I can enter a username with user [username] then when I do pass [password] I get -ERR Authentication failed. I know the user info is correct. When I set up an account in Outlook Express I get "There was a problem logging onto your mail server. Your Password was rejected:" Also saying -ERR Authentication failed.'. (0x800ccc90,0x800ccc92) So basically the same thing. I can attach the tutorial I used in as a .doc if that would help.

[Dovecot] Dovecot LDA with SetUID
by Michael 01 Jan '10

01 Jan '10

Has anyone been able to get Dovecot LDA working where each user has a different UID? All the howtos on the Internet I have found set the UID of a mailbox as fixed for all users. However I have tried to run it on the current SQL database we have (with different UID per user) and I get the following: Jan 1 16:25:40 HOST dovecot: deliver(EMAIL): Fatal: setgid(1000(stdusers)) failed with euid=8(mail), gid=12(mail), egid=12(mail): Operation not permitted I am calling this from Postfix with: dovecot unix - n n - - pipe flags=DRhu user=mail:mail argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${recipient}

[Dovecot] Quota with Dict + SQL not updating
by Michael 01 Jan '10

01 Jan '10

Hello all, I have a Dovecot server deployed with a MySQL back end. If the user logs in and there is no quota set for them in table 'quota', the system will automatically inset a line with their username and current messages/storage. However after this it fails to update the information when to reflect new messages coming to their inbox after the original insert of the information. It will only update the information when a user deletes a message. Why is it not updating this information every time their mail is checked with IMAP? Cheers, Michael

[Dovecot] Oracle SQL driver
by Alexander Bukharov 31 Dec '09

31 Dec '09

Hi all. Recently I was looking for an IMAP-server with Oracle support and unfortunatelly I couldn't find one. It was a surprise for me but there is no such functionality at all. So I've chosen an IMAP-server with most flexible and convinient architecture that was Dovecot-1.2.9 and written a driver for Oracle RDBMS support. I used Oracle Pro*C so a Pro*C preprocessor is needed to compile the driver. There is a lot of logging there that should be removed. It would be great if you consider to include this driver to mainstream so Dovecot will be the first IMAP server supporting Oracle as auth backend. All related files are attached. Cheers.

[Dovecot] A Dovecot Sieve spam filter question.

31 Dec '09

Hi, I'd like to make a filtering threshold for users to let them deal with spamassassin spam-level starred < 8 themselves, but spam-level starred higher than 8 should be discarded how can one do that with the "anyof" option ? the following doesn't work with a test email with "gtube", which scores > 999 : # require "fileinto"; if header :matches "X-Spam-Level" "\*\*\*\*\*\*" { fileinto "discard"; } and I think it would be nice to have not so many lines in the globalsieverc file.

Shouldn't this result in the mail being delivered to the inbox as a new message (ie. without the \Seen flag)? require "imap4flags"; addflag "\\Seen"; removeflag "\\Seen"; Every message gets delivered to the inbox as though it's already been read.

[Dovecot] Hostname setting defaults
by Timo Sirainen 30 Dec '09

30 Dec '09

Any thoughts about the following? hostname setting currently defaults to system's host name, without the domain part. It's used (in v2.0): - dovecot-lda (new deliver): If -a parameter isn't specified and there's no Envelope-To: header, the destination address is generated as <username>@<hostname setting> - lda/lmtp: In generated Message-Id: headers ("dovecot-stuff@<hostname>") for rejects, vacation, etc. - lda/lmtp: in reject messages as part of MIME boundary, and also in "Reporting-UA: <hostname>; Dovecot mail delivery agent" header. - lmtp: In the protocol, e.g. "220 <hostname> Dovecot ready" or "421 4.4.2 <hostname> Disconnected for inactivity" - lmtp: In added Received: header Seems pretty clear to me that it should be host.domain.org, not just host. So I suppose I'll change that default. The other thing is postmaster_address. That's accidentally been postmaster(a)example.com in dovecot-example.conf and uncommented. So who knows how many installations have their postmaster address set to that.. I'm thinking of just commenting it out in next v1.2 release so admins needs to change that. But for v2.0 maybe there could be a good default for postmaster_address? "postmaster@<hostname setting>" I think? Because it's postmaster(a)host.domain.org instead of postmaster(a)domain.org, it might not be correct in most installations, but I'm thinking that maybe it's safer. Someone trying out Dovecot on testbox.biguni.edu probably doesn't want bounces going to postmaster(a)biguni.edu..

[Dovecot] dovecot-shared
by Frank Cusack 30 Dec '09

30 Dec '09

I'm confused about dovecot-shared. If the file exists, \SEEN flags are NOT shared? So if dovecot-shared exists, flags are actually private. The doc seems clear on this (albeit not worded very well). I only question it because intuitively you would think the opposite. If backwards compatibility is the reason for this reverse behavior, the file should have been named dovecot-private-flags. In fact that's a great name to stick a list of flags (one-per-line) that are private. -frnak

Re: [Dovecot] Retrieve Physical Message Filename
by Tony Rutherford 30 Dec '09

30 Dec '09

Thanks for the reply. I won't be changing any files, or even accessing them, i'll simply be passing the filename along to "another system". I'm not allowed to change this other system or any of its interfaces. The other system has been in place and is "off limits" as far as changes go (I'm told). To make it simple, this other system needs to be notified of any flag changes on emails. So, when we detect a flag change (in our plugin), we need to pass the message filename along to this other system. I hope this makes sense...and again...i'm not justifying the need for it, but I have to play the hand i'm dealt....Tony RutherfordSoftware EngineerBlueTie Inc.arutherford(a)bluetie.com(585) 586-2000 x1040-----Original Message-----From: "Timo Sirainen" [tss(a)iki.fi]Date: 12/29/2009 04:02 PMTo: "Tony Rutherford" CC: dovecot(a)dovecot.orgSubject: Re: [Dovecot] Retrieve Physical Message FilenameOn Tue, 2009-12-29 at 15:50 -0500, Tony Rutherford wrote: > Hi,Using Dovecot 1.2.9 with Maildir and Layout=FS.In a plugin, i'm > overriding "update_flags":void my_mail_update_flags(struct mail > *_mail, enum modify_type modify_type, enum mail_flags flags)For this > email which is having its flags updated, I need to retrieve the > physical filename of the message.

The problem is that by the time you're trying to access the file, its flags may have already changed, which also means its filename could have changed. So even if you got it, your code would probably randomly fail. What exactly are you going to do with the filename? Maybe you should instead be opening the file with mail_get_stream() and doing something with the fd. This message is intended solely for the individual(s) to whom it is addressed.

by Cliff Hayes 30 Dec '09

30 Dec '09

Hello, What does this information mean and how is it relevant? I cannot find documentation other than a brief description in dovecot.conf: %t - number of TOP commands %p - number of bytes sent to client as a result of TOP command %r - number of RETR commands %b - number of bytes sent to client as a result of RETR command Thanks in advance, Cliff

[Dovecot] Mail storage creation fails with virtual users
by Scott H. W. Snyder 30 Dec '09

30 Dec '09

So I have recently set up dovecot with a virtual users dovecot.passdb file, but when I attempt to telnet in, it fails because my virtual users don't have proper permissions to create mailboxes. I don't want to have to create actual users for each email account. Any idea as to what to do? The error that dovecot logs: dovecot: Dec 28 13:06:28 Error: IMAP(user1): mkdir_parents(/var/mail/ folders/user1) failed: Permission denied dovecot: Dec 28 13:06:28 Error: IMAP(user1): Mail storage creation failed with mail_location: mbox:/var/mail/folders/user1/:INBOX=/var/ mail/user1 dovecot: Dec 28 13:06:28 Error: child 27667 (imap) returned error 89 my [test] passdb file: user1:{PLAIN}pass1:2001:2001:User 1 Name:/var/mail/folders/user1:: mail_plugins=cmusieve user2:{PLAIN}pass2:2002:2002:User 2 Name:/var/mail/folders/user2:: mail_plugins=cmusieve user3:{PLAIN}pass3:2003:2003:User 3 Name:/var/mail/folders/user3:: mail_plugins=cmusieve user4:{PLAIN}pass4:2004:2004:User 4 Name:/var/mail/folders/user4:: mail_plugins=cmusieve Conf settings: -bash-3.2# /usr/local/sbin/dovecot -n # 1.0.13: /usr/local/etc/dovecot.conf base_dir: /usr/local/var/run/ log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot.info.log protocols: imap listen: *:143 ssl_disable: yes disable_plaintext_auth: no login_dir: /usr/local/var/run//login login_executable: /usr/local/libexec/dovecot/imap-login login_greeting: Hi buddy, have an account ? max_mail_processes: 2048 verbose_proctitle: yes first_valid_uid: 1000 last_valid_uid: 5000 mail_location: mbox:/var/mail/folders/%u/:INBOX=/var/mail/%u mail_debug: yes mbox_read_locks: dotlock fcntl auth default: verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd-file args: /usr/local/etc/dovecot.passdb userdb: driver: passwd-file args: /usr/local/etc/dovecot.passdb socket: type: listen master: path: /usr/local/var/run/dovecot-auth-master mode: 432 user: dovecot group: mail
