[Dovecot] stats plugin + UID command continuation
by Mike Abbott 27 Oct '10

27 Oct '10

When using the stats plugin for dovecot-2.0, UID commands that "continue" cause infinite recursion and crash. For example, "A22 UID FETCH 151 BODY[]" when the body is 3MB or so always crashes. For smaller messages, this command logs the duration twice. Here is a patch to fix it: --- stats-plugin.c.orig 2010-10-26 20:18:13.000000000 -0500 +++ stats-plugin.c 2010-10-26 20:19:10.000000000 -0500 @@ -197,6 +197,9 @@ commands = array_get_modifiable(&imap_commands, &count); for (i = 0; i < count; i++) { + if (strcasecmp(commands[i].name, "UID") == 0) + continue; + hash_table_insert(orig_cmds, (char *)commands[i].name, commands[i].func); commands[i].func = stats_command;

[Dovecot] Smart boxes
by Marcelo Salhab Brogliato 27 Oct '10

27 Oct '10

Hi, I'm using dovecot as IMAP server. I access my mails trough Mail (Mac client), iPhone and webmail. In Mail I use a smartbox that shows all my unread messages, no matter where it is. I really want this feature at my iPhone, so I'm thinking about developing a plugin that will create the smart unread box and follow these rules: - Every new mail arrived, it will create a hard link to directory .smart.unread (in case of Maildir); - Every mark as unread, it will create a hard link; - Every mark as read, it will remove the hard link; - Every mail delete, it will remove all files with same inode. This way, a smartbox with all unread messages will be available into webmail, iPhone and every IMAP client. What do you think about it? Is there a simple way? If it is a cool feature, I'll develop it and post the plugin here. Regards, Marcelo

[Dovecot] Dovecot's maildir format / is rm safe
by ian＠comtek.co.uk 26 Oct '10

26 Oct '10

Is it considered 'safe' to delete directly from a dovecot Maildir? I mean things of the form: rm Maildir/cur/1288062016.M581217P9422.alpha,S=1873,W=1900:2,S The wiki tells me 'If you wish to modify them in any way, create a new message instead and expunge the old one. ' but it doesn't mention deleted files. Specifically I'm wondering what happens with: dovecot.index dovecot.index.cache dovecot.index.log dovecot-uidlist Since (http://wiki.dovecot.org/IndexFiles) tells me these files index each message is there a chance of Dovecot breaking badly if it can't find them? Is it intelligent enough to automatically update the above files when it finds a missing message file? Would simply deleting the 4 files be appropriate? I have users with 4 gig mailboxes so I really wouldn't want to be deleting those files in a script every night if its a long winded process to regenerate them. Thanks in advance for any help, Ian

[Dovecot] Solicitud de atributo mailPlugins en el ldap
by Antonio Perez-Aranda 26 Oct '10

26 Oct '10

Antes del piloto o durante el piloto deberíamos tener este atributo disponible en el ldap. El campo debe de ser único y admitir información en una línea. En un principio, para los usuarios con búsquedas tendría el contenido "fts fts_squat" Para la segunda fase será un requisito casi indispensable, puesto que por este campo configuraremos algunos parámetros específicos de Solr y que sean diferentes para algunos usuarios.

[Dovecot] post-login scripting using PHP
by Maciej Uhlig 26 Oct '10

26 Oct '10

I'd like to write post-login script using PHP. I noticed every shell post-login script ends with: exec "$@", which effectively executes dovecot's script-login. However, while I try to do the same (?) in PHP: $prog = $argv[1]; exec ("$prog"); it doesn't work. The client timeouts, dovecot (2.0.6) says "Disconnected for inactivity". May be I don't clearly see the way post-login scripting should work. Any hint to make it done? Regards, MU

[Dovecot] Exchange-replacement with SOGo
by Timo Sirainen 26 Oct '10

26 Oct '10

I thought some people here would be interested: Recently SOGo added support for OpenChange, which means Outlook can natively access it via MAPI the same way as Exchange. Everything is open source, and the great thing about SOGo is that it uses existing IMAP server for mails rather than reimplementing yet another one itself. They seem to prefer Cyrus, but apparently Dovecot should work too. For non-mail (calendar, etc) it uses SQL, but I heard it's not too difficult to replace that either if someone would prefer some NoSQL database or something. http://www.sogo.nu/ http://www.openchange.org/

[Dovecot] doveadm-expunge not expunging when ran from cron
by LEVAI Daniel 26 Oct '10

26 Oct '10

Hi! I noticed that this command ... : for USERNAME in ${USERS};do /usr/local/bin/doveadm -Dv expunge -u "${USERNAME}" mailbox sa.* SAVEDBEFORE 1d done ... does not expunge mails if ran from crontab. It shows in the Debug output what would have been done, but it doesn't really expunge those mails. This command runs daily, and every day the list of expunged mails (in the Debug output) just grows and grows, and the sa.* directories stay the same (except the new mails of course). However, if I run it from a terminal it really expunges the mails. Example output: doveadm(root): Debug: Loading modules from directory: /usr/local/lib/dovecot doveadm(root): Debug: Module loaded: /usr/local/lib/dovecot/lib10_quota_plugin.so doveadm(root): Debug: Loading modules from directory: /usr/local/lib/dovecot/doveadm doveadm(root): Debug: Skipping module doveadm_expire_plugin, because dlopen() failed: Cannot load specified object (this is usually intentional, so just ignore this message) doveadm(root): Debug: Module loaded: /usr/local/lib/dovecot/doveadm/lib10_doveadm_quota_plugin.so doveadm("${USERNAME}"): Debug: expunge: box=sa.spam uid=6657 doveadm("${USERNAME}"): Debug: expunge: box=sa.spam uid=6658 doveadm("${USERNAME}"): Debug: expunge: box=sa.spam uid=6659 doveadm("${USERNAME}"): Debug: expunge: box=sa.spam uid=6660 doveadm("${USERNAME}"): Debug: expunge: box=sa.spam uid=6661 doveadm("${USERNAME}"): Debug: expunge: box=sa.spam uid=6662 [...] If ran from cron, then the same uids show up every day, and new ones gets added (as new mails gets copied into those directories). Is there something fishy going on in doveadm-expunge if it has no controlling terminal?
