[Dovecot] Unseen messages question
by Antoine Nguyen 14 Apr '12

14 Apr '12

Hi list, this question is related to the IMAP protocol itself, not really to Dovecot. I'm trying to understand what is the more efficient way to maintain the number of unseen messages of the currently selected mailbox. RFC3501 says a client must not issue a STATUS command to the selected mailbox and that information sent by a SELECT is enough. My current idea follows these steps : * Issue a STATUS before the mailbox is selected => I know how many unseen messages it contains * SELECT the mailbox => I got the eventual first unseen message in this mailbox but I don't understand how this info can be useful * Maintain the unseen counter (on client side) according to what the user do * Send a NOOP command every X minutes and look at the RECENT response to see if there are new messages I think it works pretty well when the mailbox is opened only once. Let's imagine this mailbox is opened twice, by different clients. If one client marks a message as \Seen, how can the second client know about this change? Thanks for your help, Antoine Nguyen http://modoboa.org/

[Dovecot] How do I test if the anti spam plugin is working?
by Dr Josef Karthauser 14 Apr '12

14 Apr '12

I've configured the dspam anti spam plugin, but it doesn't appear to be doing anything when I move mail between mailboxes. Can anyone help me determine what's going on? The plugin appears to be loading; at least if I don't define all the required configuration options I get a complaint in the log file. But beyond that I don't see any activity. Here's the config: babel# dovecot --version 2.1.3 The dovecot anti spam plugin config is: protocol imap { mail_plugins = $mail_plugins antispam } and plugin { antispam_debug_target = syslog antispam_verbose_debug = 1 antispam_backend = dspam antispam_signature = X-DSPAM-Signature antispam_signature_missing = error antispam_trash_pattern_ignorecase = trash;Deleted * antispam_spam_pattern = SPAM antispam_dspam_binary = /usr/local/bin/dspam antispam_dspam_args = --deliver=;--user;%n@_%d } I don't even appear to be seeing any log entries from the plugin. I've moving an email from my main mailbox into a mailbox called 'SPAM', which is how I thought that it was supposed to be triggered. Cheers, Joe

[Dovecot] Problems with Apple Mail and attachments
by Helga Mayer 12 Apr '12

12 Apr '12

Hello, has anyone experiences with the Apple mail client, to be precise : Mail 5.2? When I copy a message with an attachment from the inbox to a different folder using 'move' or 'copy' , Apple Mail does not properly display the attachment in the new folder. When I copy the same message using 'archive' the attachment shows up properly. There is no difference on the server side. We are using maildirs. The raw messages in the various folders are identical. Deleting plist on the Mac didn't help. After removing and recreation of the account (client side) the attachments are displayed correctly again. Is this an apple problem or has it got anything to do with dovecot.index.cache ? Kind Regards Helga Mayer

[Dovecot] vacation plugins for squirrelmail
by Daminto Lie 12 Apr '12

12 Apr '12

Hi, I am afraid I have a question to ask of you all. I have just completed setting up a mail server running on Ubuntu Server 10.04. It has postfix, dovecot 1.2.19, LDAP and squirrelmail as the webmail. I have also created virtual users accounts on the system through LDAP. I can send and receive mails which is great. Now, what I am trying to do is to set up a vacation auto-reply on the squirrelmail so that users who are about to go on vacation can set it up themselves. I was looking around for the vacation plugins for dovecot that I can incorporate it into squirrelmail. Any help would be very much appreciated. Thank you

[Dovecot] ldap idle connection timeout in DoveCot 1.0.13?
by Zhou, Yan 12 Apr '12

12 Apr '12

Hi there, We are using DoveCot 1.0.13, it connects to LDAP server for authentication. It seems that DoveCot keeps the idle LDAP connection open. Our firewall is terminating these connections after some time of idle activity (2 hours), then, we run into authentication problem. If we restart either LDAP or DoveCot, then it is fine. Can we set some kind of LDAP idle connection timeout in DoveCot? /etc/dovecot-ldap.conf. I do not see any configuration available for 1.0.13. Another alternative is to set idle connection timeout in LDAP, but we prefer doing that in DoveCot.

[Dovecot] lazy_expunge questions
by James Devine 11 Apr '12

11 Apr '12

I'm messing around with lazy expunge and I just had a couple of questions. If I delete messages or folders with messages, I see them being moved to the expunge namespace, but if I delete an empty folder, all traces of it seem to disappear. Is there a way to move empty folders to the expunge namespace also? My second question is in regards to restoring folders. If I try to execute the imap command 'RENAME EXPUNGED/TEST INBOX/TEST' I get 'NO [CANNOT] Can't rename mailboxes to/from expunge namespace'. Just wondering if this is possible or do I need to recreate the folder and then move messages into it.

[Dovecot] Bug tracker
by Timo Sirainen 11 Apr '12

11 Apr '12

I started thinking that perhaps I should move my TODO list to a bug tracker. But because of reasons I've explained a few times before, I don't want a full blown public bug tracking system. The requirements for it are: * I am the only person who can add new bugs. Everyone else reports bugs/requests to this mailing list as before. (Well, I guess Stephan could use this as well if he wants to.) * Everyone can comment existing bugs. * Dovecot mailing list integration: Commenting a bug sends a mail to the mailing list. Replies to those comments go back to bug tracker (probably based on some [#1234] tag in subject). I would have the option of adding a comment that doesn't go to the mailing list (= adding some internal comment that nobody else cares about). Notifications about new bugs won't go to the mailing list (most likely it was created due to a recent mailing list post). So the main difference to how things work now is that people would be able to easily browse existing bugs and add comments to them. I would add bugs there only when I'm not planning on fixing them within a few days. I wouldn't add each and every feature request there, only the things that I'm actually interested in developing. So the idea would be to actually get the bug tracker emptied at some point, not to be a graveyard of unimportant feature requests that about 1-2 people in the world would want. So, any suggestions for what software could do these things? I think Request Tracker has those features, but it's not really the nicest/prettiest thing.

[Dovecot] Proxy and SSO (single sign-on)
by Miguel Tormo 11 Apr '12

11 Apr '12

Hello, I have a running setup with a dovecot imap4/pop3 proxy to a few dovecot backend servers which actually store the mailboxes. This is running smoothly and allows me to transparently distribute mailboxes. I'm using some "extrafield" configured in the LDAP passdb. However, now I would like to use GSSAPI (preferred) and NTLM for single sign-on. Both are pretty straightforward to configure in a single instance environment, but I don't know if they would work with proxy. For example, with GSSAPI there are two cases: 1) Just use gssapi mechanism, without PAM. Then, it a user presents a ticket the passdb ldap is not used, so the extrafields are never read. 2) Use gssapi and PAM (thus allowing using a kerberos password). But the extrafields feature isn't available with PAM passdb driver, so again the proxy won't work. The case for NTLM would fall into the first case, I think. Am I right regarding this scenario? Is there a way I could make SSO and proxying work? I'm currently using dovecot 2.0.16 (had to patch it to increment LOGIN_MAX_INBUF_SIZE to 4096 for GSSAPI to work, as I read somewhere in this list), but I could upgrade to a newer version if that allows all this to work. Thanks!

[Dovecot] Folder Aliases - Revisited Yet Again
by Daniel L. Miller 11 Apr '12

11 Apr '12

I just did a search through my archives - seems this topic has been requested a few times since my posting two years ago. I asked about a specific implementation - which Mr. Sirainen never commented on. He was probably focused on something more important at the time - like a paying job. So I'll ask again... Calling Timo! If we can't get clients to agree on a "standard" set of folders (probably reasonably safe assumption) and if protocol implementations of variations of "*LIST*" are too far in the future...what about having alternative folder names presented based on login name - maybe by an extension? So where my usual login might be "user(a)domain.com", and that would continue to be supported as the default login, I could now have "user(a)domain.com+thunderbird", "user(a)domain.com+mobile", etc.? And each of those extensions would then have a system-wide map defining folder name relationships, like "Sent=Sent Items". Does this seem doable? -- Daniel

[Dovecot] F5 SLB iRule - POP3 TLS Offload & Add Realm
by Lee Standen 11 Apr '12

11 Apr '12

Hey Guys, I figured someone might have use of this at some point. I've created an iRule for our F5 Load Balancer which performs the following tasks: - Appends STLS to the POP3 Capability list (it does this blindly, so expects the backend POP3 server to not return this) - Watches for the STLS command and initiates SSL negotiation with the client (leaves the connection to the backend POP3 server unencrypted) - Watches for the USER command (login attempt) and appends a realm if the user hasn't supplied one - Stops watching once a successful login occurs It's designed to be attached to port 110 and port 995 at the same time, and will disable SSL if the user is connecting to port 110 until the STLS command is issued. This is a first pass, so there's probably room for improvement, but it does seem to work. This will require LTM v10 (at least), as the SSL::collect command didn't exist prior to that version. Here's the rule: when CLIENT_ACCEPTED { if { [TCP::local_port clientside] == "110" } { # Disable SSL if we're on port 110 (as we're doing TLS Offload) set secure 0 SSL::disable } else { set secure 1 } set realm "mydomain.com" set debug 0 set loggedin 0 } when SERVER_CONNECTED { TCP::collect } when CLIENTSSL_HANDSHAKE { SSL::collect set secure 1 } when CLIENTSSL_DATA { if { $debug } { log local0. "CLIENT DATA: [SSL::payload]" } set lcpayload [string tolower [SSL::payload]] if { $lcpayload starts_with "user" } { scan [SSL::payload] {%s%s} command user set pos [string first $user [SSL::payload] 0] SSL::payload replace $pos [string length $user] "$user@$realm" if { $debug } { log local0. [SSL::payload] } } SSL::release if { $loggedin == 0 } { SSL::collect } } when CLIENT_DATA { if { $debug } { log local0. "CLIENT DATA: [TCP::payload]" } set lcpayload [string tolower [TCP::payload]] if { $lcpayload starts_with "stls" } { TCP::respond "+OK Begin TLS negotiation\r\n" TCP::payload replace 0 [TCP::payload length] "" TCP::release SSL::enable return } elseif { $lcpayload starts_with "user" } { scan [TCP::payload] {%s%s} command user set pos [string first $user [TCP::payload] 0] TCP::payload replace $pos [string length $user] "$user@$realm" if { $debug } { log local0. [TCP::payload] } } TCP::release if { $loggedin == 0 } { TCP::collect } } when SERVER_DATA { if { $debug } { log local0. "SERVER DATA: [TCP::payload]" } set lcpayload [string tolower [TCP::payload]] if { $lcpayload starts_with "+ok logged in" } { TCP::release set loggedin 1 event disable if { $debug } { log local0. "POP3 Login Successful" } return } elseif { $lcpayload contains "capa" } { TCP::payload replace [expr [TCP::payload length] - 3] 0 "STLS\r\n" } if { $secure == 1 && $loggedin == 0 } { clientside { SSL::collect } } elseif { $secure == 0 && $loggedin == 0 } { clientside { TCP::collect } } TCP::release if { $loggedin == 0 } { TCP::collect } }

[Dovecot] Username from rfc822Name subject alternative name
by Бранко Мај ић 11 Apr '12

11 Apr '12

Hello, I'm looking into adding support for extracting the username from client certificate's rfc822Name (from the subjectAltName extension). The question I have is what would be the best approach to do this? Current implementation has a kind of clean code since it just goes through the subject name, extracting the values with X509_NAME_get_text_by_NID (while NID is obtained with OBJ_txt2nid). If I were to add this, it's bound to make the code a little bit more complicated since SAN's can't be retrieved in the same way. So far in terms of options I have, I can see the following: 1. Create a distinct configuration option for the ssl_cert_username_field (i.e. specify something like "sanrfc822Name" to have Dovecot extract the username from the designated alternative name). 2. Make the current code fail-over to rfc822Name SAN if emailAddress is provided for ssl_cert_username (less invasion in code, but less flexibility as well). Any input/recommendation/directioning is welcome. I've wanted to actually first write a patch, and then submit it, but I think it might be better to check what would be preferable by Dovecot maintainers/devs. Best regards -- Branko Majic Jabber: branko(a)majic.rs Please use only Free formats when sending attachments to me.

[Dovecot] Dsync test on 2.1.3
by Jitendra Bhaskar 10 Apr '12

10 Apr '12

Hi, I am using dovecot version 2.1.3 on centos. I tested dsync from my live server to one of backup server. But I got that its working for most of the user and there is problem for few user. Some users got duplicated mail to their mailbox and I saw there is some extra folders i.e Sent Items_* , Draft_* and Trash_* in few users mail box. and I synced only from main server to backup server. I didn't enable mail_plugin in backup server. My configuration for testing of Dsync on master server is as: mail_plugins = $mail_plugins notify replication service aggregator { fifo_listener replication-notify-fifo { user = vmail mode = 0666 } unix_listener replication-notify { user = vmail mode = 0666 } } service replicator { # start replication at startup process_min_avail = 1 } plugin { #host1 replicates to host2 mail_replica = remote:root@backup_server } #dsync_remote_cmd = ssh -l%{login} %{host} doveadm dsync-server -u%u -l%{lock_timeout} -n%{namespace} dsync_remote_cmd = ssh -l root %{host} doveadm dsync-server -u%{user} -l%{10} -n%{namespace} service doveadm { user = root } And in backup server : service doveadm { user = root } 1. Problem is I am not getting why some user getting lots of duplicate mails. 2. Why duplicate folders like Sent Items_* and Trash_* created for few users 3. I used only one way syncing then why both replicated. Note: i am using root only for testing purpose * Thanks & Regards * *Jitendra Kumar Bhaskar* Cell:- +91 7306311531 +91 8102997821

[Dovecot] 2.0/2.1 - different behavior for LIST-EXTENDED
by Peter Mogensen 10 Apr '12

10 Apr '12

Hi Timo, We are sitting here wondering if this difference in behaviour between dovecot 2.0.17 and 2.1.3 is intended. When you create a folder, subscribe to it and rename it (without changing the subscription) these are the behaviours: For 2.0.17: . list (SUBSCRIBED) "" "*" RETURN (STATUS (MESSAGES)) * LIST (\Subscribed \NonExistent) "." "INBOX.test" For 2.1.3: . list (SUBSCRIBED) "" "*" RETURN (STATUS (MESSAGES)) * LIST (\Subscribed) "." "INBOX.test" * NO Mailbox doesn't exist: test If you don't use rfc5819 the folder will just get silently ignored by dovecot 2.1.x, but if you actually try to get the number of messages you'll get the error. It seems to me from reading rfc5258 that the 2.0.x behaviour is the correct ?? /Peter

[Dovecot] Problem with quota warning
by Patrick Westenberg 10 Apr '12

10 Apr '12

Hi again, my test environment is working now and finally I tried to implement my quota warning but it is not working. LDA says the mailbox is full even it is not (only 81% and that is why the quota warning is executed). Further I used :noenforcing in my script.

[Dovecot] Multiply mailboxes vs one huge
by Alexander Chekalin 10 Apr '12

10 Apr '12

Hello, as I need to store a lot of messages on my IMAP server (order of 900K-1000K; this is an archive for some time, maybe a year or so), I see some "slowness" in dealing with such a huge amount. I mainly need to do searches like "get all messages from user1(a)domain1.com to user2(a)domain2.tld recieved between date1 and date2". So I really interested will it be wise to a) split all messages into several smaller mailboxes (per-month, or per-day, or create 2-level-structure like "month/day/") b) use dbox (vs currently used mbox) storage scheme (I'm afraid of mdbox as I still not sure I'll be able to parse it by scripts later "just in case") Dovecot is the latest one (2.1.3). No compression Dovecot-side, but it mails are in zfs volume with compression on. I ask this mainly due to my not fully understand how Dovecot indexes are working. I also test another approach: to use my own index somewhere outside Dovecot which will store reference between emails and UIDs, and dates and UIDs, so I'll simple query my index for things I need. But then, that's exactly what IMAP index can do, so I simple slow my search down, isn't it? The only reason I think about my own index is I won't use 'all header' as search scope, I need to deal only with From:, To:, Cc:, Bcc: (if any), Recieved (if nowehere else I see the from/to info), and date field(s) - I doubt IMAP will care for that for me. Yours, Alexander
