[Dovecot] Plugin
by Alex Baule 27 Jan '10

27 Jan '10

Hello Everyone... Some time ago, i send some questions about plugins and concat 2 file handles. So, there is another questions about this. Timo Sirainen send to me this modification, in src/lib-storage/index/maildir/maildir-mail.c struct istream *full_input[3]; full_input[0] = i_stream_create_fd(fd, 0, TRUE); full_input[1] = i_stream_create_fd(fd1, 0, TRUE); full_input[2] = NULL; input = i_stream_create_concat(full_ input); This is necessary because my Header and Body is splited. This modification works fine. My question is: There is a way to do this with a plugin ? I dont know how to implement this in a plugin, because i dont know what is the hook to change the maildir_open_mail functions. (this is the function with the modification above) . Another question is: There is a seek function, in dovecot, and in zlib plugin, it is rewrite by another function, that use the "gzseek" to do the seek. My splited body will be encrypted, and the crypto no have seek, because the message will be encrypted. (if i open the message, decrypt and seek to some position, maybe work). The seek function is really necessary to IMAP and maildir ?

[Dovecot] Are Mail files in /Maildir/cur & /Maildir/.Sent read-only ?
by CoolAtt NNA 26 Jan '10

26 Jan '10

Hi ALL... I want to know if the files in /Maildir/cur & /Maildir/.Sent are modified by dovecot. I have a script which calculates the age of the mail files. I think that if they are continuously modified by dovecot I won't be able to calculate the age of the files. Can Anyone plz advise on this....

[Dovecot] read-only dovecot-uidlist
by Cor Bosman 26 Jan '10

26 Jan '10

Hi all, i just investigated a user complaint and found a read-only dovecot-uidlist. Since dovecot couldnt write it, the process failed. Users can not reach this file, so how this became readonly is beyond me. Must be something in dovecot. Maybe an older bug? Doing a search now for more readonly uidlist files, but that'll take a few hours. Cor

[Dovecot] dovecot-antispam for dovecot 2.0?
by Adam Seering 26 Jan '10

26 Jan '10

Hi, Just wondering, is there a development version or the like of the dovecot-antispam plugin, that works with the Dovecot 2.0 beta? I'm starting to poke at the new version (mdbox looks really handy for my use case); I'm also starting to play with dspam, but I'm finding it annoying to train dspam without it having direct access to my (rather-large existing) spam folder... Thanks, Adam

[Dovecot] backup & restore mailbox files manually
by coolatt 26 Jan '10

26 Jan '10

Hi ALL... Am working on a solution to backup maildir mailboxes using rsync. All mailbox directories are mirrored on another machine. I need advise regarding restore of the INBOX & SENT files from the backup. For e.g , [1] Can I just copy "file-x-y-z" from /Maildir/cur to restore it on /Maildir/cur on the mailserver. [2] Can I do same for SENT emails ? Thanks CoolAtt -- View this message in context: http://old.nabble.com/backup---restore-mailbox-files-manually-tp27303434p27… Sent from the Dovecot mailing list archive at Nabble.com.

Hello, reading the wiki I found http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy?highlight=(no DNS resolving) I have a setup where the destination of a proxyconnection is an DNS name.

[Dovecot] acl flag to limit imap_acl based acl changes
by Amon Ott 26 Jan '10

26 Jan '10

Hi all! I have tried the imap_acl plugin with 1.2.9 today, but was not able to limit acl changes for those mailboxes where acl changes should be forbidden. http://wiki.dovecot.org/ACL says that "a" or "admin" covers "Administration rights to the mailbox". However, removing "a" from owner acl (using "lr") does not help, the user can still change all acl flags for all users with imap. Write accesses to mails are forbidden as they should. Is this intended or a bug? We would like to give all users the ability to use ACLs through IMAP, but the current behaviour endangers our read-only mail archives.

[Dovecot] Released Pigeonhole Sieve v0.1.15 and ManageSieve v0.11.11 for Dovecot v1.2.10
by Stephan Bosch 25 Jan '10

25 Jan '10

Hello Dovecot users, It's been a while since the last Pigeonhole Sieve and ManageSieve releases. That is why this release includes quite a few changes. Most interestingly, the include extension is updated to match the most recent specification, the Sieve interpreter now includes plugin support and ManageSieve now has support for enforcing quota on the size of scripts, the number of scripts and the space the scripts occupy on disk. Other than that, quite a few small bugs were fixed. One of which was in the i;ascii-numeric comparator. If one of the matched strings did not start with a digit, the comparator would always yield a 'less-than' result. In stead it should have considered the string starting with the non-digit character as having a positive infinite value. Elsewhere in this list, Julian Cowley pointed out that negative values also start with a non-digit character, which some people may not have understood (i.e. i;ascii-numeric works only on unsigned values). The bug fix in this release could therefore change result of certain misconceived (and probably spam-related) Sieve rules, so watch out! I started work on the spamtest(plus) and virustest extensions. These are implemented for the most part, but their configurability needs quite a bit more work. Changelog Sieve v0.1.15: * Enotify extension: - Adjusted notify method API for addition of new notification methods. - Set default importance level to 'normal' (was 'high'). * Include extension: updated implementation towards most recent specification (all should be backwards compatible): - Implemented global variables namespace. - Global command may now appear anywhere in a script. - Implemented script name checking using the requirements specified in the ManageSieve draft. - One issue remains: ManageSieve currently requires included scripts to be uploaded first, which is not according to specification. * Changed envelope path parser to allow to and from envelope addresses that have no domain part. + Added preliminary support for Sieve plugins and added support for installing Sieve development headers. + Started work on the implementation of the spamtest, spamtestplus and virustest extensions (unfinished). + Deprecated notify extension: implemented denotify command. + Variables extension: added support for variable namespaces. + Added configurable script size limit. Compiler will refuse to compile files larger than sieve_max_script_size. + Testsuite changes: - Added support for changing and testing an extension's configuration. - Added a command line parameter for copying errors to stderr. - Fixed a bug in the i;ascii-numeric comparator. If one of the strings started with a non-digit character, the comparator would always yield less-than. - Imap4flags extension: fixed bug in removeflag: removing a single flag failed due to off-by-one error (bug report by Julian Cowley). - Improved EACCES error messages for stat() and lstat() syscalls and slightly improved error messages that may uccur when saving a binary. - Vacation extension: fixed typo in runtime log message (patch by Julian Cowley). - Fixed use of minus '-' in man pages; it is now properly escaped. - Fixed parser recovery. In particular cases it would trigger spurious errors after an initial valid error and sometimes additional errors were inappropriately ignored. Changelog ManageSieve v0.11.11: * This release contains adjustments to match changes in the Sieve API. This means that this release will only compile against Pigeonhole Sieve v0.1.15. + Implemented ManageSieve QUOTA enforcement. + Added MAXREDIRECTS capability after login. + Implemented new script name rules specified in most recent ManageSieve draft. - Fixed assertion failure occuring with challenge-response SASL mechanisms. - Made configure complain about trying to compile against installed Dovecot headers alone. - Fixed compile warning for compilation against CMUSieve. The releases are available as follows: Sieve: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.15.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.15.tar.gz.sig ManageSieve (package + patch): http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.11.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.11.tar.gz.… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.10-managesieve-0.11.11.diff… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.10-managesieve-0.11.11.diff… Refer to http://pigeonhole.dovecot.org for more information.
