[Dovecot] Several errors
by FraNL 25 Jul '09

25 Jul '09

Hi, Running OS: CentOS 5.3 (2.6.18-128.2.1.el5) 1. My Linux distribution comes with Dovecot 1.0.7. After trying to make it running, I encoutnered many problems. So I decided to upgrade to 1.2.1. When running dovecot -r from CLI, it returns with version 1.2.1. But at the top of the log file it says: Info: Dovecot v1.0.7 starting up So I am not sure which version I am running. That's the first problem. The other two problems I am having were also actual before updating to 1.2.1: 2. Every minute, the following lines (except for the timestamps, which are different, ofcourse) are being added to my log file: dovecot: Jul 24 23:54:24 Error: imap-login: USER environment missing dovecot: Jul 24 23:54:24 Error: imap-login: USER environment missing dovecot: Jul 24 23:54:24 Error: child 3712 (login) returned error 89 dovecot: Jul 24 23:54:24 Error: child 3713 (login) returned error 89 dovecot: Jul 24 23:54:24 Error: imap-login: USER environment missing dovecot: Jul 24 23:54:24 Error: child 3714 (login) returned error 89 3.

[Dovecot] Are host names a secret?
by Timo Sirainen 24 Jul '09

24 Jul '09

Some time ago I added the ability for IMAP clients to fetch messages' GUIDs using FETCH X-GUID command. Because of a bug it wasn't working in 1.2.0 or 1.2.1, but I've fixed it now. But now I'm starting to wonder: With Maildirs the GUIDs are the maildir base filenames, which contain host names. Is it a bad idea to expose them to users?

[Dovecot] Maildir from offlineimap, INBOX folder created
by Ng Oon-Ee 24 Jul '09

24 Jul '09

Hi, I'm using dovecot to serve up a Maildir created/served by offlineimap. The layout is typical (as far as I know) of maildirs, with the root folder having cur, tmp, new, and subfolders being a folder within the root folder. Since I'd previously used Evolution to access this maildir, my subfolders were actual subfolders (separator /). Anyway, it all works spiffingly well, except that I can't see my inbox at all. What happens is that attempting to subscribe to Inbox will create an INBOX folder in the root folder, which is (of course) empty, so I see an empty folder. For completeness, my dovecot -n... # 1.1.17: /etc/dovecot/dovecot.conf # OS: Linux 2.6.30-ARCH x86_64 ext3 protocols: imap listen: localhost ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_location: maildir:/home/data/Profiles/OfflineIMAP/root:LAYOUT=fs auth default: passdb: driver: pam userdb: driver: passwd Thanks for the help.

[Dovecot] Problem with sieve scripts including sieve scripts
by Mauricio Tavares 23 Jul '09

23 Jul '09

I have the following global cmusieve scripts defined in /etc/dovecot/sieve, which is owned by the user deliver is run (virtual) as defined in the lda session of dovecot.conf: global-spam.script ====================================== require ["fileinto"]; # Move spam to spam folder if header :contains "X-Spam-Level" "********************" { fileinto "Spam"; # Stop here so that we do not reply on spam stop; } elsif header :contains "X-Spam-Flag" "Yes" { fileinto "Spam"; stop; } global-default.script ==================================== require ["include"]; include :global "global-spam.script"; i.e. all the default script does is call the spam script. I have created the compiled versions using sievec, making sure they are still owned by virtual: mail sieve # ls global-default.script global-spam.script global-vacation.script global-default.scriptc global-spam.scriptc global-vacation.scriptc mail sieve # In the plugins session of dovecot.conf I have defined the path for global scripts (so I can do the include :global thingie) and the path for the default script (just in case user does not have a custom script in the mail directory): plugin { sieve_global_dir = /etc/dovecot/sieve/ global_script_path = /etc/dovecot/sieve/global-default.script } So I send me some certifiable spam from my collection of test spam. This is what I got from the log: Jul 22 14:49:01 mail MailScanner[15047]: New Batch: Scanning 1 messages, 3206 bytes Jul 22 14:49:01 mail MailScanner[15047]: SpamAssassin cache hit for message C04F79F002F.784A8 Jul 22 14:49:01 mail MailScanner[15047]: Spam Checks: Found 1 spam messages Jul 22 14:49:02 mail MailScanner[15047]: Virus and Content Scanning: Starting Jul 22 14:49:02 mail MailScanner[15047]: Requeue: C04F79F002F.784A8 to 304C09F0012 Jul 22 14:49:02 mail postfix/qmgr[14869]: 304C09F0012: from=<raubvogel(a)gmail.com>, size=2518, nrcpt=1 (queue active) Jul 22 14:49:02 mail MailScanner[15047]: Uninfected: Delivered 1 messages Jul 22 14:49:02 mail deliver(raub(a)domain.com): Loading modules from directory: /usr/lib/dovecot/lda Jul 22 14:49:02 mail deliver(raub(a)domain.com): Module loaded: /usr/lib/dovecot/lda/lib90_cmusieve_plugin.so Jul 22 14:49:02 mail dovecot: auth(default): master in: USER 1 raub(a)domain.com service=deliver Jul 22 14:49:02 mail dovecot: auth(default): master out: USER 1 raub(a)domain.com uid=1500 gid=1500 home=/var/spool/vmail/domain.com/raub Jul 22 14:49:02 mail deliver(raub(a)domain.com): auth input: raub(a)domain.com Jul 22 14:49:02 mail deliver(raub(a)domain.com): auth input: uid=1500 Jul 22 14:49:02 mail deliver(raub(a)domain.com): auth input: gid=1500 Jul 22 14:49:02 mail deliver(raub(a)domain.com): auth input: home=/var/spool/vmail/domain.com/raub Jul 22 14:49:02 mail deliver(raub(a)domain.com): maildir: data=/var/spool/vmail/domain.com/raub Jul 22 14:49:02 mail deliver(raub(a)domain.com): maildir++: root=/var/spool/vmail/domain.com/raub, index=, control=, inbox=/var/spool/vmail/domain.com/raub Jul 22 14:49:02 mail deliver(raub(a)domain.com): cmusieve: /var/spool/vmail/domain.com/raub/.dovecot.sieve doesn't exist Jul 22 14:49:02 mail deliver(raub(a)domain.com): cmusieve: Using sieve path: /etc/dovecot/sieve/global-default.script Jul 22 14:49:02 mail deliver(raub(a)domain.com): cmusieve: Executing script /etc/dovecot/sieve/global-default.scriptc Jul 22 14:49:02 mail deliver(raub(a)domain.com): msgid=<000d01ca078a$d13122a0$6400a8c0@chameleonsh>: saved mail to INBOX Jul 22 14:49:02 mail postfix/pipe[15137]: 304C09F0012: to=<raub(a)domain.com>, relay=dovecot, delay=3.4, delays=3.3/0/0/0.1, dsn=2.0.0, status=sent (delivered via dovecot service) From what I gathered, mailscanner saw it was spam and tagged it.

[Dovecot] 1.1.8 upgrade to 1.2

Hi, I'm hoping to upgrade to 1.2 in the next couple of days. I remember seeing something mentioning some sort of config change, but unfortunately I don't remember where I saw it nor what the config option was.

Hi, I'm using version 1.2.1 with acl. How do I use acl_shared_dict? Especially with file:-dictionary. What's the layout of that file? Is it possible that the file is ignored with the current version? If the file doesn't exist or isn't readable, I don' get any error message. Best regards, Sven

[Dovecot] Released Sieve v0.1.9 for Dovecot v1.2.1
by Stephan Bosch 23 Jul '09

23 Jul '09

Hello Dovecot users, Relatively many bugs and problems were reported recently in a short period of time. Apparently, now that Dovecot v1.2 is finally stable, the new Sieve plugin is also starting to get used much more. No known bugs remain. Let's hope I didn't spawn any new ones. Apart from the bugfixes I made the deprecated notify plugin implementation compatible with CMUSieve. You can use it, but keep in mind that the (rather stupid) denotify command is not (yet) implemented and that the $text$ substitution does not work (yes, there is a world of differences compared to enotify). Changelog Sieve v0.1.9: * Removed the unfinished sieve-filter tool from the default build. It is now only built when the --with-unfinished-features switch is supplied during configure. + Started building support for the ereject version of the reject action, which has a preference to use an SMTP/LMTP protocol error in stead of a bounce message. This is to be used to make the Sieve plugin honour Deliver's -e parameter. This is not yet finished and not built by default. + Improved 'Permission denied' error messages just like Dovecot does, precisely specifying what permission is missing to access or create a file. + Added additional headers to the list of allowed headers for the address test. The restrictive nature of the address test is not always appropriate. Still thinking of a better, less restrictive implementation. + Made the deprecated notify extension compatible with the old CMUSieve plugin. However, the denotify command and the $text$ substitution are not yet supported. + Made the discard action log a message to avoid confusion about disappearing messages. - Fixed behavior of fileinto when delivering into a namespace prefix. It now uses silent delivery into INBOX as fallback. - Fixed logging of folder namespace prefix upon delivery into a prefixed namespace. Formerly it only logged the bare folder name. - Fixed a potential segfault in the argument validation. It didn't surface because no command could have a :tag followed by an associated parameter as last argument. - Fixed segfault bug occuring in envelope test when performed on null (<>) envelope path. The fix involves a rather large restructuring of the code to make sure envelope addresses are properly handled everywhere (bug reported by Nikita Koshikov) - Envelope: fixed bug in application of address parts; failure to obtain the part would cause inappropriate match success (bug reported by Ron Lee) - Fixed extension conflict checks during validation. It could sometimes produce useless errormessages. This is currently only used by the deprecated extensions. - Forgot to remove old explicit storage library dependency (patch by Arkadiusz Miskiewicz). - Fixed compiler warnings on certain platforms regarding the use fwrite for outgoing message construction -- The releases are available as follows: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.9.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.9.tar.gz.sig -- Have fun testing the new releases and don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] Compiling Dovecot
by Jason Silkey 23 Jul '09

23 Jul '09

I'm attempting to compile Dovecot 1.2.1 from source with support for ManageSieve, with little success. ./configure seems to complete successfully, but make fails with the message: make: *** No targets. Stop. I checked the Makefile, and it's empty. I run into the same problem no matter the configure options, with or without the managesieve patch applied, and even with earlier versions (I also tried 1.2.0 and 1.1.17 just to see if it would work, but no go). I've had no problems compiling other software, so I'm at a bit of a loss here. Any thoughts?
