[Dovecot] Roadmap
by Jonathan Siegle 05 Dec '08

05 Dec '08

I've been running 1.2alpha3 for weeks now without issue. However, some people in my testing department object to even testing "alpha" code. Are there specific features/bugs that need resolved before alpha reaches beta? Thanks, Jonathan

[Dovecot] Dovecot authenticating to multiple kerberos realms
by Romer Ventura 04 Dec '08

04 Dec '08

Hello, I got Postfix, Dovecot 1.1.7 configure to use pam and the pam.d/dovecot file is configure to use pam_krb5 module. Everything is working with no problems, but I am finding that the user must type the domain part in uppercase in order to successfully authenticate. So I am wondering if there is any way for the user to login as user1(a)domain.com instead of user1@DOMAIN.COM...? Any ideas..? Thanks

[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 This script was created to suit my needs, so, have some paths in the code... It's not very "user friendly" yet... but if have intereting I will implement others features (like a config file). Download here: http://allan.cassaro.googlepages.com/blockthis.py Regards.

[Dovecot] my_vsnprintf crash on HP-UX

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.

[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
