[Dovecot] Does a script exist to fix broken maildir timestamps?
by drbob 26 Apr '08

26 Apr '08

Hello, When I upgraded to dovecot (changing servers at the same time) in November last year I copied the maildirs from my old server without using the -p option to preserve timestamps! Since my mail client displays the email dates based on the Date header rather than the imap "internaldate" I didn't notice the problem until today when I tried to migrate an account to gmail using imapsync and found that all emails prior to November display the wrong date in the web interface (they show the date they were copied in November). I feel very silly. Before I go try to hack together a script which parses all my older email files and changes the timestamps to the time recorded in the "Date:" header, does anyone know if robust, tested version of such a script is alrady available? Would correcting the timestamps in this way cause any problems for dovecot (e.g in the index files)? Thanks in advance for any help. drbob NB In my googling for a solution to this problem I found this hack to imapsync which would rewrite the "internaldate" based on the date header during a sync. Whilst I'd rather fix the timestamps that are the source of the problem, it may be useful for others finding this post in the future, see: http://www.zimbra.com/forums/installation/237-received-date-appears-incorre…

[Dovecot] Mixing LDAP and static
by Anders 25 Apr '08

25 Apr '08

I want to read quota size from LDAP, but I have a static value for home. How can I mix these? Right now, I have this LDAP configuration: user_attrs = uid=home=/var/mail/vhosts/%d/%n,gosaMailQuota=quota_rule=*:bytes=%$M which works fine, but looks up the uid attribute needlessly, and is not scalable: I have to pick a different, always-existing LDAP attribute for each static extra field that I want to set. Is there some LDAP configuration syntax like the SQL "SELECT '/var/...' AS home" ? Thanks, Anders.

[Dovecot] 1.0.5: many pop3-login processes?
by Alan Ferrency 25 Apr '08

25 Apr '08

Hello, We are running dovecot 1.0.5 on a test server, with FreeBSD 6.2 (though I have noticed the same problem since dovecot versions in the 0.99 range). We don't have very many simultaneous pop/imap users, but we have a proliferation of pop3-login processes. Currently we have 128 such processes. We have 11 imap-login processes, but only a few actual imap processes running. Is this normal? Can we stop it? Is anyone else successfully running dovecot on FreeBSD 6.2? Thanks for your help.

[Dovecot] Problem with Dovecot Delivery Agent, Extra "From" lines and mbox
by Hokan 25 Apr '08

25 Apr '08

When an mbox email contains a line that looks like a "Mail" header it should be quoted (per RFC 4155). Sendmail's delivery agent does this, as does Procmail delivery agent. Dovecot deliver does not do this. Example line, with ">" quote: >From hokan(a)hokan.org Thu Mar 8 17:28:01 2008 When reading email (IMAP) that contains such an unquoted line, the email abruptly ends before the "Mail" line. There may (or may not) appear another email (visible to the client) that contains the rest of the email. -- Hokan MEnet, a wholly owned subsidiary of Enet System Administrator Department of Mechanical Engineering hokan(a)me.umn.edu Institute of Technology 612.626.9800 University of Minnesota

[Dovecot] Authentication: Dovecot -> Vpopmail - > MySQL with one table per domain
by James Nordstrom 25 Apr '08

25 Apr '08

Hi All, I am using Dovecot 1.0.13 with Vpopmail (Qmail Toaster current) backed by MySQL with one table per domain (--disable-many-domains) . What I cannot figure out is how to have Dovecot authenticate to Vpopmail when Vpopmail uses one table per domain. Basically I need dynamic SQL in the Dovecot-sql.conf file. Currently I have: password_query = select pw_clear_passwd as password from domainname_com where pw_name = '%n' I need something like password_query = select pw_clear_passwd as password from %d where pw_name = '%n' Where %d is the name of the table. I can't use the exact domain name at it will not match the vpopmail format domainname_com. I would be happy to use some sort of sting builder but and not sure what my options are in the .conf file. Please help Thanks in advance James James Nordstrom Nordstrom Design Inc. E-mail: james(a)nordstromdesign.com US: 908-419-5597 Europe: 001/908-419-5597

[Dovecot] Index maintenance
by Anders 25 Apr '08

25 Apr '08

Hi. I am unable to find information about what happens to the index file if I use something like the cron script at the bottom of http://wiki.dovecot.org/Plugins/Expire There must be some information in the index that is no longer needed. When and how will Dovecot clean this up? Thanks, Anders.

[Dovecot] sieve header :matches for multiline header
by Anton Yuzhaninov 25 Apr '08

25 Apr '08

RFC3028 say: Folding of long header lines (as described in [IMAIL] 3.4.8) is removed prior to interpretation of the data. The folding syntax (the CRLF that ends a line plus any leading whitespace at the beginning of the next line that indicates folding) are interpreted as if they were a single space. But it seems to be not true for dovecot-sieve-1.0.2 for header Received: from example.ru (example.ru [192.168.105.14]) by myserver (Postfix) with ESMTP id D4DA5D85927 This sieve test work: header :matches "Received" "from *by myserver (Postfix) with ESMTP id *" But this test not work, while should also work according to RFC: header :matches "Received" "from * by myserver (Postfix) with ESMTP id *" -- WBR, Anton Yuzhaninov

[Dovecot] ACLs generating plugin problems.
by "Fábio M. Catunda" 25 Apr '08

25 Apr '08

Hi! I'm trying to use an ACL to avoid deletion of messages that are inside .Trash folder, the ACL is already working very well, the problem that I'm facing is that even if the message is not deleted, mail_log logs that it has been deleted. Also, in some cases part of the lazy_expunge code is executed too, but sometimes I just dont know where the message is, thats weird. I erased deleted and expunged folders, then I deleted a message, It hasn't been deleted, but "deleted" and "expunged" folders has been created. Anyway, I would like to know if there is a way to stop plugin execution when an ACL matches. Thanks a lot.

[Dovecot] alert function, V2
by Stewart Dean 25 Apr '08

25 Apr '08

I guess the alert function is not part of the spec, because it appears to be unimplemented in Dovecot, even though most clients implement it. Timo, I would hope this would be easy to implement, and it's functionality that will be valuable to every installation. Here's why. America recently had the tragedy of a shooting rampage on a large university campus (yes, America should do something about the violence and free access to guns in our culture/society). What was worse was that, due to the lack of an emergency notification process, some 20+ people died needlessly. Now all college and university administration are scrambling to set up emergency notification processes. Our first take on this is a massive all-hands mailing list, but a) best case, it would take 15 minutes (and as much as an hour) to get to everybody's mailbox. b) users would have to read through their mail and stumble on the message What's needed is an "in-your-face" unavoidable alert, and the UWIMAP alert functionality provides this. As I recall, you touch just about anything in your IMAP client and there's a popup message in the middle of the client IMAP window...and it happens repeatedly. We tried it back 3-4 years ago and found it too annoying to use. For this purpose, it's perfect. The wy UWIMAP did it, the presence of the file /etc/imapd.alert triggers it, and the text in that file is transmitted to the client. The message has to be short, a one-liner for a small popup window, but this could be a pointer to a shared system message folder. Of course, DC could sense the activation of the alert in some other fashion that the presence of a file. Ideally, whatever activates the alert function should be able to be turned on remotely; I had in mind to do it using a mail aliases that is a pipe to a executable...

[Dovecot] Rare problem with Indexes?
by richs＠whidbey.net 25 Apr '08

25 Apr '08

We've been running 1.1 rc3 now for about a month, and overall it's been very fast and stable. There is however an Index-related problem that keeps cropping up which prevents a user from accessing their mailbox until their Indexes are manually removed. Somehow, an Index becomes problematic, and Dovecot hangs forever when the mailbox is accessed. It manifests when a user logs in and issues a "SELECT INBOX", or "GETQUOTAROOT" when "maildirsize" needs rebuilding. When Dovecot hangs, no data is returned and no further commands are accepted, and the daemon must be killed. We see no errors in the logs, but have yet to catch the problem with "mail_debug" enabled. We're using NFS with Maildir's and these related options: mail_location = maildir:/mail/%Lu/Maildir:INDEX=/mail/%Lu/Cache mmap_disable = yes mail_nfs_storage = yes mail_nfs_index = yes mail_drop_priv_before_exec = yes mail_cache_min_mail_count = 128 mailbox_idle_check_interval = 5 maildir_stat_dirs = yes maildir_copy_with_hardlinks = yes maildir_copy_preserve_filename = no Has anyone else run across the need to purge Indexes manually? Could this be unrecoverable Index corruption, or a locking issue? We've made a copy of the mailbox when the problem occurs. However, when we test it later, Dovecot re-builds the "dovecot.index" file itself just fine, and functions normally. We plan to "mail_debug" when this happens next to see if we can get more information. Thanks! -Rich

[Dovecot] Dovecot features
by Phan Thanh Diện 25 Apr '08

25 Apr '08

Hi, We would like to switch from courier-imap to dovecot. I have installed dovecot on a machine running FreeBSD 6.3 and now testing it. My questions are below: 1. Can I configure dovecot to delete all files that are older, say 10 days, from defined mail boxes (for example Trash or Spam). 2. After I access mail box (using web mail squirrel imap) all emails moved from 'new' directory to 'cur'. Then messages are not accessible for pop3. Such behavor doesn't occur with courier-imap. Can I force dovecot to behave like courier-imap? Many thanks for help. Dien Phan

I recently switched one of our 30 imap servers to 1.1RC4 from 1.0.x, and the difference is huge. The load on the server dropped from 5+ to 0.3 or so. This means there is no more io waiting going on. Thats on FreeBSD 6.2. Great work Timo! Cor

[Dovecot] dovecot: Fatal: IMAP(user2): write(event_pipe) failed: Bad file descriptor

Hello. Since I upgraded few months ago from version 1.0 to 1.1 (right now using v1.1.rc4) in logs for some users only (but in different servers) I noticed errors: dovecot: Fatal: IMAP(user2): write(event_pipe) failed: Bad file descriptor dovecot: Fatal: IMAP(user3): write(event_pipe) failed: Bad file descriptor So only for some imap users. And in different servers. And this error happens suddenly, I already tried to delete delete cache and index files. However the users themselves haven't noticed any problems.

[Dovecot] Sieve script executed, but nothing happens
by Wouter Amsterdam 24 Apr '08

24 Apr '08

Hi all, I think I have almost solved my dovecot-deliver lookup problems, but now sieve still fails to work. From deliver's logfile I can tell the user's homedir is found and the sieve script is executed, but not as expected. My sieve testscript is very basic: /home/virtual/user.dovecot.sieve: ************* require "fileinto"; if address :is "to" "user@ mydomain.nl" { fileinto "sieve"; ( I also tried INBOX.sieve, without succes) } ************* But incoming messages for this account are still delivered in the normal inbox, not in the sieve folder. Why won't this work? /var/log/deliver: ************* deliver(user(a)mydomain.nl): Apr 17 09:55:40 Info: Loading modules from directory: /usr/lib/dovecot/lda deliver(user(a)mydomain.nl): Apr 17 09:55:40 Info: Module loaded: /usr/lib/dovecot/lda/lib90_cmusieve_plugin.so deliver(user(a)mydomain.nl): Apr 17 09:55:40 Info: auth input: user(a)mydomain.nl deliver(user(a)mydomain.nl): Apr 17 09:55:40 Info: auth input: home=/home/virtual/user deliver(user(a)mydomain.nl): Apr 17 09:55:40 Info: auth input: uid=5000 deliver(user(a)mydomain.nl): Apr 17 09:55:40 Info: auth input: gid=5000 deliver(user(a)mydomain.nl): Apr 17 09:55:40 Info: maildir: data=/data/mail/mydomain/user deliver(user(a)mydomain.nl): Apr 17 09:55:40 Info: maildir: root=/data/mail/mydomain/user, index=/data/mail/mydomain/user, control=, inbox= deliver(user(a)mydomain.nl): Apr 17 09:55:40 Info: cmusieve: Using sieve path: /home/virtual/user/.dovecot.sieve deliver(user(a)mydomain.nl): Apr 17 09:55:40 Info: cmusieve: Executing script /home/virtual/user/.dovecot.sievec deliver(user(a)mydomain.nl): Apr 17 09:55:40 Info: msgid=<20080417075530.5E8BD20111(a)termsrv.mydomain.local>: saved mail to INBOX ************* TIA, Wouter

[Dovecot] using mysql from within a plugin
by Alexander Prinsier 24 Apr '08

24 Apr '08

Hello, I'm trying to access a mysql database in a plugin. -What special compiler flags do I need? I discovered that when I don't explicitly link lib-sql/libsql.a in, then I get an undefind symbol error about sql_init when loading the plugin. Shouldn't the imap process itself have sql support linked in, rather than each plugin? -It appears that I need to call sql_drivers_init() and sql_drivers_register_all() before sql_init. Again, shouldn't the imap process do this, instead of each plugin? It should probably only be called once, so if one plugin already does it, then the second one will create problems. -When linking libsql.a in, and calling the functions mentioned above, then I get this error when starting dovecot: undefined symbol: mysql_ssl_set I'm guessing it's part of the mysql library itself, not dovecot. Can someone give me some hints on how to use dovecot's mysql library in a plugin? Thanks, Alexander

[Dovecot] Sharing Folders - or views?
by Nigel Allen 24 Apr '08

24 Apr '08

Hi All Running Dovecot v1.0.3 on FC 6. We have a Dovecot account which contains folders used by all staff. Think of the account as "Customers" and the folders as "Customer-1", "Customer-2", "Customer-3" and so on. We currently have around 650 of these customer folders. The problem is that there are currently 12 members of staff who need to see a subset of these folders (i.e. the customers that they are the manager for) but who also need to see (sometimes) the entire range of customer folders. Ideally what they would like to see is this kind of layout: +Personal Folders Inbox Trash Copies + My Customers Cust-1 Cust 7 Cust-25 Cust 33 + All Customers Cust-1 Cust-2 Cust-3 Cust-4 Cust-5 Cust-6 Cust-7 etc I suppose we could achieve this with symlinks but thought I would ask in case there is a "clever" way to achieve the same end. Thanks and Regards Nigel. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

[Dovecot] Windows Mobile and IMAP proxy
by Onno Molenkamp 24 Apr '08

24 Apr '08

Hi, We are running Dovecot proxies in front of our Dovecot IMAP servers, and were having problems with Windows Mobile clients not being able to connect. The clients would send a LOGIN command, and immediately after the succes reply a LOGOUT command. It turns out the Windows Mobile IMAP client gets confused by the IMAP proxy first sending the command tag in the reply and then, in a seperate packet, the rest of the line. Although not being able to handle this looks like a very bad design to me (how can one ever expect to read a full line in a single read() call?) I fixed it in our Dovecot proxies because we do have clients that want to use it. Attached is my fix for the problem. Onno

[Dovecot] disconnect error

a user complain about suddent disconnect error from time to time (he's using pop3 with Apple Mail) Looking at dovecot logs I discover that, each time the error shows up for him, I have this : dovecot: pop3[95137]: Info: user=<dan(a)userdomain.com> Disconnected top=0/0, retr=0/0, del=0/4, size=127101 but all other "regular" pop3 session looks like this one : dovecot: pop3[94777]: Info: user=<dan(a)userdomain.com> Disconnected: Logged out top=0/0, retr=0/0, del=0/3, size=67947 What is the difference beetween "Disconnected: Logged out" and "Disconnected" and how can I solve this ?

[Dovecot] Adding new storage backend to Dovecot
by Earl Dreller 24 Apr '08

24 Apr '08

I'm exploring adding a new storage backend to dovecot, storing mail in some sort of database, and had a few questions. Hoping someone here might be able to help :) -Is all of the 'storage' specific code in housed in lib-storage/index? Would adding a new storage backend be as simple as recreating all of the public functions of the current /mbox or /maildir code such as they pertain to that storage mechanism? -Where is the particular storage method controlled? I've had a look around but can't seem to find where the decision to use the 'mbox' or 'maildir' code is. -Finally, if there isn't a filesystem associated with the mail storage area, obviously the index data code will need to change somewhere. Any ideas on the complexities of that? Thanks!
