[Dovecot] Disallow Deletion from Trash Folder
by Bradley Rintoul 01 Mar '13

01 Mar '13

Hello: I've been tasked with trying to find a way to keep users from ever "permanently" deleting emails. The users are running Thunderbird and are using the "Archive" option for when emails are deleted. However, they are still able to delete emails from the Archive folders... I'm wondering if there's any way that I can configure Dovecot to make sure that emails *never* get removed from the filesystem. I know it's probably kind of a bizarre request, but is there any way that Dovecot can help me out in this regard? Thanks! B. Rintoul

[Dovecot] Support for PolarSSL?
by Charles Marcus 01 Mar '13

01 Mar '13

Hey Timo, Just curious if you ever thought about supporting other than just OpenSSL? PolarSSL looks really interesting, has no major dependencies and is very lightweight compared to OpenSSL, GNUTLS or others... https://polarssl.org/ I guess it could be a lot of work, or not, anyway, I'm just curious... -- Best regards, */Charles/*

[Dovecot] Best practice for sieve script synchronization
by Oli Schacher 01 Mar '13

01 Mar '13

We consider deploying a two server active-active setup with dsync replication for ~2500 users. I was wondering how people handle sieve script synchronization in such setups. We came up with a few options for syncing: 1) rsync/unison ~/sieve every x seconds 2) move sieve dirs to separatate partition and sync with gluster or drbd 3) patch roundcube managesieve sieve plugin to upload to both managesieve servers (only roundcube can access managesieve in our setup) 4) store sieve scripts in mysql and patch roundcube managesieve plugin to directly access the db instead of using managesieve (we tried this, but apparently sieve scripts read from db via dovecot dict can't have more than one line? show stopper due to roundcube sieve plugin needing comments to parse the scripts) 5) wait until Timo/Stephan add additional magic to dsync for sieve scripts as discussed in http://www.dovecot.org/list/dovecot/2011-October/061699.html ;-) We are tending towards 1) as this seems simplest and most robust solution but before we re-invent the wheel we'd like to "hear" your thoughts...

[Dovecot] sieve /editheader / addheader :last crash
by Peter Rindfuss 01 Mar '13

01 Mar '13

Hi Everybody, I'm using dovecot 2.1.14 from http://xi.rename-it.nl/debian/ with debian squeeze stable. In general, sieve works fine for me, but "addheader :last ..." from the editheader extension causes a crash when it processes a message. I was able to narrow this down a bit: It only happens if "addheader :last" is the first editheader command executed in a script. If it is preceded by any "deleteheader" or "addheader" without ":last", everything is fine. This is what I get from sieve-test when it crashes: sieve-test(root): Panic: file istream.c: line 133 (i_stream_read): assertion failed: (_stream->skip != _stream->pos) sieve-test(root): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x4881a) [0x7f5e0b37681a] -> /usr/lib/dovecot/libdovecot.so.0(default_fatal_handler+0x32) [0x7f5e0b376902] -> /usr/lib/dovecot/libdovecot.so.0(i_error+0) [0x7f5e0b349f7f] -> /usr/lib/dovecot/libdovecot.so.0(i_stream_read+0x17c) [0x7f5e0b37da9c] -> /usr/lib/dovecot/libdovecot.so.0(+0x51453) [0x7f5e0b37f453] -> /usr/lib/dovecot/libdovecot.so.0(+0x5150e) [0x7f5e0b37f50e] -> /usr/lib/dovecot/libdovecot.so.0(i_stream_read+0x69) [0x7f5e0b37d989] -> /usr/lib/dovecot/libdovecot.so.0(+0x53fe1) [0x7f5e0b381fe1] -> /usr/lib/dovecot/libdovecot.so.0(i_stream_read+0x69) [0x7f5e0b37d989] -> /usr/lib/dovecot/libdovecot.so.0(i_stream_read_data+0x52) [0x7f5e0b37dc72] -> /usr/lib/dovecot/libdovecot.so.0(io_stream_copy+0x41) [0x7f5e0b38ae21] -> /usr/lib/dovecot/libdovecot.so.0(+0x5e1de) [0x7f5e0b38c1de] -> /usr/lib/dovecot/libdovecot.so.0(o_stream_send_istream+0x33) [0x7f5e0b38acb3] -> /usr/lib/dovecot/libdovecot-storage.so.0(maildir_save_continue+0x38) [0x7f5e0be0caf8] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_storage_copy+0xb8) [0x7f5e0be376d8] -> /usr/lib/dovecot/libdovecot-storage.so.0(maildir_copy+0x56) [0x7f5e0be086c6] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_copy+0x4a) [0x7f5e0be3ce9a] -> /usr/lib/dovecot/libdovecot-sieve.so.0(+0x3fa66) [0x7f5e0c103a66] -> /usr/lib/dovecot/libdovecot-sieve.so.0(+0x366b4) [0x7f5e0c0fa6b4] -> /usr/lib/dovecot/libdovecot-sieve.so.0(sieve_result_execute+0x3ff) [0x7f5e0c0fabef] -> /usr/lib/dovecot/libdovecot-sieve.so.0(sieve_execute+0x56) [0x7f5e0c10b456] -> sieve-test(main+0x73e) [0x403a5e] -> /lib/libc.so.6(__libc_start_main+0xfd) [0x7f5e0abdec8d] -> sieve-test() [0x403219] Aborted Best regards Peter

Re: [Dovecot] IMAP folders sort order

But I tried to create a fresh account in Dovecot (not migrated from Courier), and it still shows a intermixed folder order: a list "" * * LIST (\HasNoChildren) "/" "Spam" * LIST (\HasNoChildren) "/" "Sent" * LIST (\HasNoChildren) "/" "Drafts" * LIST (\HasNoChildren) "/" "Trash" * LIST (\HasNoChildren) "/" "INBOX" * LIST (\HasNoChildren) "/" "Pub" a OK List completed. So, it is not a migration problem -- note that it is the LIST command output, so it is not got influenced by some IMAP client folder searchlist/mask or its namespace settings (like in Thunderbird) WBR, valery

[Dovecot] patch for crash while FTS-searching through virtual mailbox
by Mike Abbott 28 Feb '13

28 Feb '13

FTS-searching through a virtual mailbox crashes dovecot-2.1.15 when the FTS backend does not support lookup_multi. src/plugins/fts/fts-api.h says for fts_backend_lookup() that "The arrays in result must be initialized by caller." FTS backends can therefore assume that the arrays are initialized by their caller. However, fts_backend_lookup_multi() does not initialize the per-box arrays before calling the FTS backend’s lookup function. This patch fixes the resulting crash. --- dovecot-2.1.15/src/plugins/fts/fts-api.c 2012-08-03 09:09:28.000000000 -0500 +++ dovecot/src/plugins/fts/fts-api.c 2013-02-28 14:35:43.000000000 -0600 @@ -337,8 +337,12 @@ result->box_results = p_new(result->pool, struct fts_result, i+1); for (i = 0; boxes[i] != NULL; i++) { + struct fts_result *box_result = &result->box_results[i]; + p_array_init(&box_result->definite_uids, result->pool, 32); + p_array_init(&box_result->maybe_uids, result->pool, 32); + p_array_init(&box_result->scores, result->pool, 32); if (backend->v.lookup(backend, boxes[i], args, - and_args, &result->box_results[i]) < 0) + and_args, box_result) < 0) return -1; } return 0;

[Dovecot] header brakage on sieve redirect ?
by Lazy 28 Feb '13

28 Feb '13

Hi all, In the sieve file require ["copy"]; redirect :copy "asdf(a)asd.pl"; emails with headers containing \n in non terminated " field like Cc: xxx <xxx(a)plus.pl>, "asd, Grzegorz " <xxxxx(a)nsn.com> Subject: RE: RF after redirecting them Cc: xxx <xxx(a)plus.pl>, "asd,\ \ Grzegorz " <xxxxx(a)nsn.com> Subject: RE: RF mail delivered locally by dovecot-lda is unaltered lack of space before second \ brakes the headers. I'm investigating if this isn't cosed by qmail-inject, but my first suspect is sieve. dovecot 2.0.13, sieve 0.3.3, dovecot-delivery is used as an exclusive lda for qmail Regards, Michal Grzedzicki

[Dovecot] Public free (libre) mailbox hosting service for everybody!
by אנטולי קרס נר 28 Feb '13

28 Feb '13

Hello e-mail software developers and users! I'd like to ask all of you a question. And of course hear relevant opinion. I've been using free software happily for a few years, and I found free/open source alternatives for many popular proprietary tools such as Facebook, Dropbox, Micro$oft Windows & Office, Youtube, Skype and many many others. Some of the alternatives are probably known to some of you, while others are still unknown to many. But I couldn't find a replacement to mailbox hosting. I'm using a Gmail mailbox and I hate it. So many free and open source mail servers and I still use Gmail, a closed-source service (which also probably tracks all my data, including Google searches I do, and uses it for all kinds of statistics and advertising, but that's another issue). So I asked myself, why is there no mailbox hosting service which respects user freedom? I sent an e-mail to the Free Software Foundation, and got a suggestion to ask all of you: do you know any free (libre) mail server out there? If you do, please inform me, and the whole free software community, developers and users. I couldn't find any. If nobody else finds any either, the plan is to start a new server. There are so many server tools and programs, like the ones you use and develop. It's just like hosting a Git repository or videos of pictures for the masses. We can do it with e-mail too. Q: Why don't I start my own personal server? A: I'm a programmer and I can do it - with some effort, but I can. The problem is not me. The problem is that all the non-programmer and non-technical users can't. And they shouldn't. We tech people can, and should, run such servers for everybody. For all users who want their basic freedoms respected. Another question to tech people: I'm not an expert in e-mail software, so I'm not really sure setting up a server is as easy as all other online services we get, such as Diaspora (facebook replacement), MediaGoblin (Youtube replacement), Gitorious (git repo hosting). Is there a technical issue preventing people from running a mail server, or it's just a matter of having enough money to run it, and the necessary technical skills (which many of you probably have). If it's possible, we'll do it. Also, if users had to pay for such a service, it would be okay. I don't mind paying for my free software stack. I'd actually find it a way to contribute back to the people and projects which deserve it. The point is not money; such a service can get funds. The point if FREEDOM. Waiting for response and opinions from you, my fellow free software community members, Anatoly Krasner Free software enthusiast/activist Israel
