[Dovecot] Antispam plugin + scriptsieve
by Allan Cassaro 03 Dec '08

03 Dec '08

Hi, I wrote a little python program that works with antispam plugin, to create or remove sieve rules based on "From:" of any e-mail that is moved to some folder configured in dovecot.conf. He works fine with "Felamimail" the email program of "eGroupware". After setup, is very simple: If an user move a message to "blocked" folder, is appended a rule in the script sieve of this user. If the message is deleted or moved out that folder, the rule is removed too. The setup is very simple: (after setup antispam plugin) Change this in dovecot.conf: protocol imap { mail_plugins = antispam } plugin { antispam_spam = Blocked antispam_mail_sendmail = /usr/libexec/dovecot/blockthis.py antispam_mail_sendmail_args = -u;%u antispam_mail_spam = -a antispam_mail_notspam = -d } Hooo... this script create a "include global script" statament in script sieve... If you don't want this feature, just comment this 2 lines: sievelist.append('require ["fileinto", "include"];\n') sievelist.append('include :global "global.sieve";\n') Here this is very useful! :D Regards.

[Dovecot] my_vsnprintf crash on HP-UX
by Marc Beyer 03 Dec '08

03 Dec '08

Hi, sorry for the double post, I stupidly composed this as a reply to an earlier mail, which causes it to appear in an older thread. Posting again so it doesn't get lost in the archives: dovecot 1.1.7 reliably crashes every time I try to open a mailbox using IMAP. Error in the logs: dovecot: Dec 02 23:14:15 Error: setmntent(/etc/mtab) failed: No such file or directory dovecot: Dec 02 23:14:16 Panic: IMAP(arandomuser(a)example.com): my_vsnprintf(): Output string too big dovecot: Dec 02 23:14:16 Error: child 4815 (imap) killed with signal 6 dovecot: Dec 02 23:14:19 Panic: IMAP(arandomuser(a)example.com): my_vsnprintf(): Output string too big dovecot: Dec 02 23:14:19 Error: child 4816 (imap) killed with signal 6 ...

[Dovecot] Loginname - mapping
by Roald Amundsen 03 Dec '08

03 Dec '08

Hi! I have a server with a few thousand mailboxes (for a few hundred domains) on it. The usernames are following several naming conventions: username_domain domain_username username_domain.tld username-domain domain.username The reason for this chaos is that the accounts were set up on different mailservers, some imail, some linux, some with virtualmin and some manually and through aquisitons etc it has all ended up in one server. Now we are setting up atmail to replace imp. The loginprocess of atmail is a bit different in that you just type in your mail address and atmail tries a few combinations of loginnames to login. However, some of the combinations over atmail cant login to. Some of them works fine when using this line in dovecot.conf auth_username_translation = @_ Is there any facility to let dovecot do username mapping? If I eg have a file: usermapping that looks like this: user(a)domain1.com domain1_user user(a)domain2.com user_domain2 user(a)domain3.com domain3.user And yes, I know that the best way is to start again and use virtual domains and get all into one naming standard, but unfortunately, that is not going to happen. The other alternative is of course to hack into the source code of atmail, but I am not that confident in PHP. Any ideas? -- Regards Roald Amundsen

[Dovecot] Problem with sieve: Keep: Generic Error
by Thomas Siebert 03 Dec '08

03 Dec '08

Hi, i came across a strange error message in Ubuntu 8.10s package (Dovecot 1.1.4) regarding sieve: sieve runtime error: Keep: Generic Error sieve_execute_bytecode(/etc/dovecot/sieve/default.sievec) failed Note that the Sieve Scripts are basically executed fine and working fine. After a lot of testing I suppose the following: "keep" doesn't detect the private namespace I have to use (courier-compatibility...), thus sieve fails to do "keep", the message is handed back to dovecot-deliver which does a "keep"-similar action itself. If I have a script with "keep;" as the only command, I get this error message. If my script is totally blank (i.e. implicit keep only), I get the same error. But if there's no implicit or explicit "keep", e.g. "fileinto INBOX;" as only command, there's no error. Also IMAP-Folders, e.g. "fileinto INBOX.Test", work. Unfortunately, "fileinto INBOX" as default is no option for me, as I use a delimiter and want to let deliver put the mails into the according IMAP-Folders. Is this a known bug? Any Ideas?

[Dovecot] Compilation of 1.1.6 fails on HP-UX 11.31
by Marc Beyer 03 Dec '08

03 Dec '08

Hi, $ uname -srv HP-UX B.11.31 U $ cc --version cc: HP C/aC++ B3910B A.06.20 [May 13 2008] Compilation fails, output of configure and make are given below. The cause of this is almost certainly that this version of HP-UX does define the QCMD macro in sys/quota.h (checked in the ifdef line 26 dovecot-1.1.6/src/plugins/quota/quota-fs.h) as well as the dqblk struct, but the latter with different fields than the Linux version. Older versions of HP-UX seem not to have contained this macro(? can't check this at the moment), which is probably why it was used to distinguish between HP-UX and Linux in quota-fs.h. Deleting lines 26-28 and 30 from dovecot-1.1.6/src/plugins/quota/quota-fs.h fixes the problem for HP-UX, but of course a real fix would need to add a more current method of distinguishing between Linux and HP-UX. If there's any more helfpul information you'd like let me know, cheers, Marc configure: ...

[Dovecot] Using namespaces to duplicate mailboxes (Doable?)
by Julio C. Ortega 03 Dec '08

03 Dec '08

Greetings. As part of a new installation of dovecot, we are exploring backup options, and wondered if it's at all possible to define a couple of namespaces where messages get duplicated to be saved in another disk for fast recovery. (we do not intent to load balance between the two, all we would like is to see if it's possible to have duplicate mailboxes so to keep a fast working backup _besides_ normal methods: tape, external disk, etc.) The whole idea behind this would be that in case of a major failure of the array holding the mailboxes, a fast working backup can be put in place. Other thing we would like to know (and i reckon it's a long shot) if it's possible to "hide" this mailbox copy from the IMAP clients, so as to prevent any user from subscribing _again_ to the same folders. Naturally this last thing is to be considered only if the former (mailbox copy trough namespaces or other dovecot _internal_ method) it's at all possible. Any feedback or better ideas are totally welcome. -- --------------------------------- Julio C. Ortega Grupo de Infraestructura ONUVA | Integración de Sistemas http://www.onuva.com

[Dovecot] data retention and e-discovery rules
by Trever L. Adams 02 Dec '08

02 Dec '08

Hello All, I am in the United States where we have e-discovery rules. Some organizations have to retain data for a certain amount of time, others are required to have a data retention policy. This means that while it should probably be possible for a user to "delete" an email so they do not see it. The server needs to store it, possibly in a tree that mirrors the folder setup of the user (so if it is in "Sales" folder, it should move to namespace "hidden", or similar, in folder "Sales"). Is there anything like this in dovecot? Is it possible to use cron jobs to see when the message was deleted (Maildir) and erase it based on policy? (Python scripts are fine if the users password isn't needed.) Thank you, Trever Adams

[Dovecot] symlink() failure in 1.2 managesieve
by Bruce A. Mallett 02 Dec '08

02 Dec '08

I've been simultaneously learning about dovecot and experimenting with the 1.2.alpha4. To start I built an rpm under CentOS 5.2 from: dovecot-1.2.alpha4.tar.gz dovecot-1.2-managesieve-0.11.2.tar.gz dovecot-1.2.alpha4-managesieve-0.11.2.diff.gz dovecot-1.2.alpha4.tar.gz dovecot-1.2-sieve-0.1.2.tar.gz and then setup with mysql to use virtual users. Mail-wise, it all works. :) Where I'm having trouble is with the managesieve part. I find that when I activate a sieve script I get a symlink() failure message in /var/log/maillog similar to this: Dec 2 05:12:47 hostname dovecot: MANAGESIEVE(account(a)hostname.com): sieve-storage: Creating symlink() hostname.com/account//.dovecot.sieve to /usr/local/virtual/hostname.com/account/sieve/Test.sieve failed: No such file or directory I began to chase this first by inserting i_info() calls into various points of the managesieve build and later by attaching to the process with gdb. I can see that in sieve_storage_script_activate() the storage->active_path member is incomplete (i.e., is not a full, absolute path name) and the cwd is "/tmp", thus the symlink() call fails. Based on what I've been reading in the documentation, shouldn't the system have resolved the "home" area for the mail to be the same as what is determined for the virtual user mail area? Using the README in the alpha4 package I've found that I can get it to work by adding the following after the "protocol manageseive {}" section: plugin { sieve=/usr/local/virtual/%d/%n/.dovecot.sieve sieve_storage=/usr/local/virtual/%d/%n/sieve } While that helps, I'm a little confused as to why I need to do this. I believe that the documentation states that the sieve defaults to .dovecot.sieve under the MAIL_LOCATION directory. So it is not clear to me if I am doing something wrong, if there is an oversight in the software and/or documentation (or perhaps my reading of it), or is it really necessary to specify the same information multiple times? - Bruce Here is some output that may be of use: -bash-3.2# dovecot -n # 1.2.alpha4: /etc/dovecot.conf # OS: Linux 2.6.18-8.1.8.el5xen x86_64 CentOS release 5.2 (Final) ext3 info_log_path: /var/log/dovecot.log protocols: imap imaps pop3 pop3s managesieve login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_executable(managesieve): /usr/libexec/dovecot/managesieve-login max_mail_processes: 100 first_valid_uid: 150 last_valid_uid: 150 mail_location: maildir:/usr/local/virtual/%d/%n mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_executable(managesieve): /usr/libexec/dovecot/managesieve mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 mail_plugin_dir(managesieve): /usr/lib64/dovecot/managesieve auth default: mechanisms: plain digest-md5 debug: yes debug_passwords: yes passdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf userdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf plugin: sieve: /usr/local/virtual/%d/%n/.dovecot.sieve sieve_storage: /usr/local/virtual/%d/%n/sieve ----- -bash-3.2# grep -v '^ *$#.*$\?$' /etc/dovecot/dovecot-mysql.conf driver = mysql connect = host=/var/lib/mysql/mysql.sock dbname=postfix user=postfix password=postfix default_pass_scheme = MD5-CRYPT user_query = \ SELECT maildir as home, 150 AS uid, 12 AS gid FROM mailbox WHERE username = '%u' password_query = select password from mailbox where username='%u'

I did some bugreports in last time and also compiled dovecot with some changes in guidance from timo to let the bug be more understandable but so far nothing helped. i like dovecot but if these bugs not get solved i cannot upgrade my maschines to > 1.0.15 :( Thanks, Andre
