[Dovecot] Execute Script on LMTP Deliver?
by Edward Carraro 10 Dec '10

10 Dec '10

Is it possible to have dovecot 2.0.8 using LMTP run a shell script each time it delivers a message to a users mailbox? I see there's an "execute = script /path/to/script" but when i added it to lmtp service in 10-master.conf, it didnt do anything and stopped delivering mail altogether service lmtp { executable = script /usr/local/bin/test.sh u% unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix user = postfix } inet_listener lmtp { port = 24 } } $ ls -lh | grep test -rwxrwxrwx 1 root staff 270 2010-12-09 18:05 test.sh $ cat test.sh #!/bin/sh USER=$1 echo $USER > /tmp/newfile basically when a message arrives, it will execute a shellscript which will notify another service that mail has arrived in their inbox

[Dovecot] Phantom INBOX in 1.2. Is there a stable .deb of 2.0?
by ian+dovecot＠comtek.co.uk 10 Dec '10

10 Dec '10

Hi, We've been running 1.2 Dovecot for a while and are happy with it. In trying to migrate from symlinks to shared folders I see a similar problem to that shown at http://www.mail-archive.com/dovecot@dovecot.org/msg32083.html . For example: . lsub "" "*" * LSUB () "." "Users..INBOX" The advice given in the thread is to upgrade to 2.0. We currently use Debian's 1.2 package and I'm reluctant to move since I can't find a stable 2.0 .deb (http://wiki2.dovecot.org/PrebuiltBinaries only has repository heads of 2.0). Building from source is an option but I'd really prefer to be using a package. Can anybody advise on an appropriate way to go? Like the original poster I am seeing INBOX under the shared namespace when I try to share. I'm also getting an empty /var/mail/virtual/users/Maildir created (maildir:/var/mail/virtual/users/%n/Maildir/). We formerly had an INBOX prefix namespace from a Courier migration too, but it has been deleted (to no avail). Shared folders do work, though. It just requires 'anyone l' in /etc/dovecot/dovecot-acls/.DEFAULT (though I'd really rather not do this!). Thanks for any help, Ian ######## mail_location = maildir:/var/mail/virtual/users/%n/Maildir/ namespace private { separator = . prefix = inbox = yes } namespace shared { separator = . prefix = Users.%%n. location = maildir:/var/mail/virtual/users/%%n/Maildir/:INDEX=~/shared/%%u subscriptions = no list = children } namespace public { separator = . prefix = Shared. location = maildir:/var/mail/virtual/public:INDEX=~/public subscriptions = no } auth default { mechanisms = plain passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } passdb ldap { args = /etc/dovecot/dovecot-ldap-master.conf master=yes } userdb passwd { } userdb ldap { args = /etc/dovecot/dovecot-ldap-userdb.conf } userdb ldap { args = /etc/dovecot/dovecot-shared-ldap.conf } } plugin { acl = vfile:/etc/dovecot/dovecot-acls:cache_secs=3 acl_shared_dict = file:/var/mail/virtual/shared-mailboxes.db }

[Dovecot] Released Pigeonhole v0.2.2 for Dovecot v2.0.8
by Stephan Bosch 10 Dec '10

10 Dec '10

Hello Dovecot users, The new Dovecot v2.0.8 release has a few changes that prompted changes in Pigeonhole as well. This means that a new release of Pigeonhole is also necessary, because otherwise things will not compile anymore. Apart from a few rather minor bugfixes, some of which originate in Dovecot, one TODO item has finally been resolved: the reject action uses the LDA mail reject API, meaning that the associated LDA settings now also work for Pigeonhole, as would be expected. Changelog v0.2.2: * LDA Sieve plugin: started using Dovecot LDA reject API for the reject extension. This means that the LDA reject_reason and reject_subject settings now also work for Pigeonhole's LDA Sieve plugin. * Did some work on the new sieve-filter tool. It is mostly functional, but it is not finished yet. * Dovecot change: services' default vsz_limits weren't being enforced correctly in earlier v2.0 releases. Now that they are enforced, you might notice that the default limits are too low and you need to increase them. This problem will show up in logs as "out of memory" errors. See default_vsz_limit and service { vsz_limit } settings. - Imap4flags: fixed segfault bug occurring in multiscript context. - Added version checking to the ManageSieve settings plugin. This plugin was forgotten when the LDA plugin was updated with this change in the previous release. - LDA Sieve plugin: fixed memory leak at deinitialization. The release is available as follows: http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.2.tar.gz http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.2.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.0 wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] Dovecot as IMAP proxy to Exchange
by Hugo Monteiro 09 Dec '10

09 Dec '10

Hello list, I'm looking into the possibility to setup dovecot to act as an IMAP proxy to an Exchange server. Things i know beforehand: - I will not be able to use the ldap (Active Directory) user DN for auth binds (but i discovered that i could could use the user userPrincipalName attribute as bind DN. I tested it using ldapsearch and it worked fine.) - I will not be able to perform any unbinded searches. - The Exchange server is unique, so i can setup a static proxy route to the server. Given the above, i'd like to post some questions: 1 - Will i be able to use auth_bind = yes given the restrictions? My first guess is that this might work if i use something like "auth_bind_userdn = %u(a)example.org" 2 - Will i be able to specify a static route to the exchange server, not having to rely on that information from the AD itself? Another thing i'd like to know is if NTLM auth can be used while dovecot acts only as proxy. Thanks in advance, Hugo Monteiro. -- fct.unl.pt:~# cat .signature Hugo Monteiro Email : hugo.monteiro(a)fct.unl.pt Telefone : +351 212948300 Ext.15307 Web : http://hmonteiro.net Divisão de Informática Faculdade de Ciências e Tecnologia da Universidade Nova de Lisboa Quinta da Torre 2829-516 Caparica Portugal Telefone: +351 212948596 Fax: +351 212948548 www.fct.unl.pt apoio(a)fct.unl.pt fct.unl.pt:~# _

[Dovecot] Dovecot 1.2/2.0 coexistence guide?
by Tom Talpey 09 Dec '10

09 Dec '10

I am running Dovecot 1.2.16 and considering moving up to 2.0.8. I have found <http://wiki2.dovecot.org/Upgrading/2.0> but there's not a lot about deploying a 2.0 server alongside an existing 1.2. Any hints on a seamless approach to this, especially one that might allow me to upgrade individual users in place, without moving their maildirs into a new tree and still avoid issues with 1.2/2.0 sharing access?
