[Dovecot] 2.1.7 TLS issues
by Christian Rößner 25 Jun '12

25 Jun '12

Hi, I have an interesting problem: I am building dovecot packages for Ubuntu since 10.04. Never had bigger trouble with it. Now since 2.1.6 or 2.1.7 (I can not say more precisely), Thunderbird 10ESR and Outlook 2010 can no longer use 143/TLS correctly. Automx delvers 143/TLS and Outlook tells me that it can not create a secure connection. I changed automx to use 993/SSL and everything works. Under Thunderbird 10ESR, I get a box that tells me that I need to change settings. When I sent mail, TB told me that it could not copy the mail to the sent folder. I also changed to 993/SSL and everything is perfect. At the other and, Apples Mail.app and iOS devices work perfectly over 143/TLS. So my guess is that it has to do with OpenSSL. Did something change in dovecot concerning TLS? Can I change options in the built process?

[Dovecot] The deleted_to_trash Plugin (workaround Outlook 2007 behaviour)
by J E Lyon 24 Jun '12

24 Jun '12

Hi, I see the plugin exists for v1 & v2, all very interesting... Surprised no one seems to have created an RPM and it looks like deleted_to_trash is one of the very few plugins to not be shipped as part of the default install with CentOS 5.5 or CentOS 6 (i.e. Dovecot v1 & v2 respectively.) Am I missing something, or does everyone really build from source? Thanks, James.

[Dovecot] Dovecot Quotas in Version 2
by Brian Spraker 24 Jun '12

24 Jun '12

Hello all, Just upgraded from Ubuntu 10.04 to 12.04 on a server today and went through a few issues that I finally got corrected with many different services. However, one of them - I absolutely cannot figure out. I was using Dovecot 1 in Ubuntu 10.04 - but in Ubuntu 12.04, it has been upgraded to Dovecot 2. Finally managed to get the configuration to work and get it to use MySQL as the back-end authentication method (had to install the dovecot-mysql package). But, I cannot get quotas to work. The moment I uncomment a quota line, Dovecot fails to start. Would appreciate any help with this. I am not using any of the individual configuration files on the conf.d folder - simply the dovecot.conf and dovecot-sql.conf file. Here is a copy of those. You can see the one commented line (mail_plugins under imap) simply will not work - but yet the one under POP works (although I don't think it is used): base_dir = /var/run/dovecot/ disable_plaintext_auth = no first_valid_uid = 33 last_valid_uid = 33 listen = * log_timestamp = "%Y-%m-%d %H:%M:%S " mail_privileged_group = www-data passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { quota = maildir quota_rule = Trash:storage=100M } protocols = imap pop3 service auth { user = root } service imap-login { executable = /usr/lib/dovecot/imap-login } service imap { executable = /usr/lib/dovecot/imap } ssl = no userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol imap { imap_client_workarounds = mail_plugin_dir = /usr/lib/dovecot/modules/imap # mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota pop3_uidl_format = %08Xu%08Xv } And for the dovecot-sql.conf file (passwords changed, of course): driver = mysql connect = dbname=horde user=<USER> password=<PASSWORD> host=localhost default_pass_scheme = PLAIN password_query = SELECT user_uid as user, user_pass as password FROM horde_users WHERE user_uid = '%u'; user_query = SELECT uid, gid, home, maildir, concat('maildir:storage=', quota) AS quota FROM horde_users WHERE user_uid = '%u'; I did not update the dovecot-sql.conf file at all - so I don't know if there maybe be some configuration issue with how it is pulling the quota limit from the database. Quotas are in bytes in the database. Certainly would appreciate any help with this. I went through the Dovecot Quota Configuration in the wiki but it wasn't any help - as I basically already have that line in the config file, but it will fail to start Dovecot. Thank you! Brian S.

Hi, after the upgrade from dovecot 2.0.13 (ubuntu oneiric) to dovecot 2.0.19 (ubuntu precise), in my logs I have a lot of these errors: Jun 23 00:20:29 server1 dovecot: master: Error: service(imap-login): child 6714 killed with signal 11 (core dumps disabled) I tested 2.0.21 and the problem is still here.

[Dovecot] Problems getting auto create plugin to work
by Dr Josef Karthauser 23 Jun '12

23 Jun '12

Hi there, I've configured the 'autocreate' plugin (in v.2.1.6), but it doesn't appear to be working. Can someone help me work out how to work out why please? I've got this in my 20-imap.conf file: protocol imap { mail_plugins = $mail_plugins antispam autocreate } and this in my 90-plugins.conf file: plugin { autocreate = Trash autocreate2 = Spam autosubscribe = Trash autosubscribe2 = Spam ... etc } But, the spam does not get created upon login. I've restart dovecot and restarted my mail client, but there's no hint of an spam folder. Is there something else that I also need to do? Thanks, Joe

[Dovecot] Import from Evolution
by Jonathan Ryshpan 23 Jun '12

23 Jun '12

I need to import the mail database generated by the evolution mail reader into dovecot. Evolution stores its mail in maildir format (fully standards compatible, I think); I would be using the maildir format in dovecot. Is there anything in the wiki, etc. explaining exactly how to do this? Why do this? Evolution is hopelessly broken, and is not likely to be fixed in the forseeable future, and I would like to keep my mails in maildir form. Reviews of kmail are very bad, and thunderbird uses the mbox format for storage. Thanks in advance - jon

sorry for replying through that links but - as you may see - replying to Jonathan will not work. If AT&T have such strange policy then i am just sorry. It sings the beginning of end of open internet if more companies will start to do this, and result in few huge corporations handling everything. Not happy world to live.

[Dovecot] cumulative userdb ?
by Benoit Branciard 22 Jun '12

22 Jun '12

in Dovecot 2.0, is it possible to have kind of "cumulative" multiple userdb ? that is, for all users: - extract some attributes (let's say: uid, gid, home) from a first userdb (Passwd for example), - an extract some other attributes (mail for example, but overwriting those from the first userdb in case of redundancy) from a second userdb (LDAP for example) ? This is *different* from the "multiple databases" setup described in http://wiki2.dovecot.org/Authentication/MultipleDatabases, where it is meant as "failover": the second database is looked up only if the user isn't found in the first database. -- Benoit BRANCIARD Service InfraStructures (SIS) - Direction du Système d'Information (DSI) Université Paris 1 Panthéon-Sorbonne Centre Pierre Mendès France B 406 - 90, rue de Tolbiac - 75634 Paris cedex 13 - France Tél : +33 1 44 07 89 68 - Fax : +33 1 44 07 89 66 Accueil tél. : +33 1 44 07 89 65 Assistance : assistance-dsi(a)univ-paris1.fr Web : http://dsi.univ-paris1.fr -- Ce message a ete verifie par MailScanner pour des virus ou des polluriels et rien de suspect n'a ete trouve.

[Dovecot] Dovecot LDA, Offlineimap and Sieve
by Johnny 22 Jun '12

22 Jun '12

Hi, I am trying to st up Offlineimap to use Dovecots LDA to be able to use Sieve for mail filtering, but am not sure how to get this working. I think the right way would be to use 'preauthtunnel' in .offlineimaprc and try the setup below, which doesn't work. ,----.offlineimaprc | [Repository LocalRepository] | type = IMAP | preauthtunnel = ssh -q localhost '/usr/libexec/dovecot/deliver -d myloginid' `---- If I go via the network card, the snch is fine, but Sieve can't be used? ,---- | [Repository LocalRepository] | type = IMAP | preauthtunnel = MAIL=maildir:$HOME/Maildir/myMailDir /usr/libexec/dovecot/deliver -d mylogonid | remotehost = localhost | port = 143 | remoteuser = mylogonid | remotepass = mypassword `---- Has anyone got any tips on how to get offlineimap to send mail to Dovecot in a way that Siev3e can be used? thanks! -- Johnny
