similar to: mbox zlib compression plugin

I've tried this on both Solaris 8 and SuSE Enterprise 9 (64-bit). I get a assert-crash when using a gzipped mbox folder . OK Logged in. .

Hello, I use mbox compressed by gzip as read-only folder (using zlib plugin).

Hello, I use mbox compressed by gzip as read-only folder (using zlib plugin). This setup worked for a while, but doesn't work with latest dovecot version (2.2.27). I have error in logs: Panic: file istream-zlib.c: line 416 (i_stream_zlib_seek): assertion failed: (ret == -1) I can see list of messages in MUA but can't ready body of any message. I've tried to delete indexes, but it

Upgraded to dovecot 2.2.15 (built from sources on Fedora linux), saw intermittent panics: From dovecot:imap Error: Next message unexpectedly corrupted in mbox file /home/xxxx/mail/Junk E-mail at 1202197 Panic: file mbox-sync.c: line 152 (mbox_sync_read_next_mail): assertion failed: (sync_ctx->input->v_offset != mail_ctx->mail.from_offset || sync_ctx->input->eof) Error: Raw

Hi, I have running dovecot 2.1.15 with zlib plugin enabled and "zlib_save_level = 6" since about 2 years now without any problems. What happens if I now change the zlib_save_level to 9? Should that work without any problems, or become the current saved "*.m" files incompatible or unreadable? Thanks Urban

zlib plugin allows opening gzipped mboxes as read-only mailboxes. However when using it, the mailbox name checks are bypassed so it's possible to open for example "../otheruser/somefile.gz". Only valid gzipped mbox files can be opened, and only if their name ends with ".gz". You can fix this by upgrading to v1.0.rc29 (available soon) or with this patch:

hi, Could anyone give some info on this plugin? When i read the wiki (http://wiki.dovecot.org/Plugins/Zlib) i'm still left with some questions... I use Maildir to store my mails, if i enable this zlib-plugin, should i 'manually' compress all messages? or wil the uncompressed messages still be accessible by dovecot? wil new messages be compressed automagically? how should the

Hello, I'm trying to get the zlib plugin working on my 2.0 server. I started with an mbox that Dovecot can read just fine. Then I gzipped it, and now Dovecot complains that it's corrupted: Error: Next message unexpectedly corrupted in mbox file /var/lib/vpopmail/domains/memoryhole.net/kyle/Maildir/Archive/Intellego.gz at 1907 Error: Unexpectedly lost From-line from

Hello, I've been playing around with using namespaces to change the way messages are stored. My idea was to use mbox for archival stuff, like this: namespace private { separator = . hidden = no inbox = yes prefox = location = maildir:%h/Maildir } namespace private { separator = . hidden = no prefix =

Hello! Always reproducible pine vs dovecot-imap-mbox.gz scene has weird errors. - Initial message is OK: [Folder "SAVE.gz" opened with 211 messages READONLY] - Some mails at the end are listed correctly, others are listed with empty sender/size/subject (just numbering). - All mails have no bodies. Full header command produces total blank screen. Even before any error message.

Hi there, got a problem with the zlib plugin, just wanted to test it on a test-mailserver, configured like in the wiki (http://wiki2.dovecot.org/Plugins/Zlib) and restarted the server. I've send an email to a blank maildir++ mailbox, the file is saved as gzip compressed file, but the "Z" flag is missing in the filename. Is that a bug in the plugin, or in dovecot? Greetings, Jan

Good evening, folks, Well, here at least. ;) I recently found out by accident about support for gzip compressed mbox files. While this is great for archives to keep wasting of space down to a minimum, unfortunately it is read only -- no support for rw access. Is implementing write access by any chance planned for future releases? Now for the spoiler. :) I mentioned, I found out about this

You can use mdbox_deleted driver to access mails with refcount 0.

Hello Dovecot v2.0.5 zlib_save_level = 6 # 1..9 zlib_save = gz # or bz2 Is there a config option to disable zlib, even if above config are in place? If so please provide an example. If no, would it be possible to add one? Like if zlib_save_level = 0 disable zlib. So one can configure per mailbox compression level via sql database. KuiZ Thanks
