Hi, I've just tried to add managesieve to our director server, and when I try to connect they fail with Jun 26 12:28:13 director2 dovecot: auth: Debug: client in: AUTH#0111#011PLAIN#011service=sieve#011secured#011session=5LNQjl3DjQAKAAsR#011lip=10.0.100.75#011rip=10.0.11.17#011lport=4190#011rport=39309#011resp=<hidden> Jun 26 12:28:13 director2 dovecot: managesieve-login: Error: proxy: host not given: user=<test1>, method=PLAIN, rip=10.0.11.17, lip=10.0.100.75, TLS, session=<5LNQjl3DjQAKAAsR> Jun 26 12:28:13 director2 dovecot: managesieve-login: Disconnected (internal failure, 1 succesful auths): user=<lgsfeacd>, method=PLAIN, rip=10.0.11.17, lip=10.0.100.75, TLS, session=<5LNQjl3DjQAKAAsR> Is it posible to use director for this?

[Dovecot] dsync error: "Mailboxes don't have unique GUIDs"
by Jeff Gustafson 25 Jun '12

25 Jun '12

I'm getting an error backing up mailboxes. I'm using the mirror command: dsync -fvo mail_home=/home/users/bob mirror ssh vmail(a)10.1.4.1 dsync -o mail_home=/home/.incoming_mail_migrations/users/bob dsync-remote(vmail): Error: Mailboxes don't have unique GUIDs: 1ef6ee37c694894d783100000581a675 is shared by INBOX and INBOX dsync-remote(vmail): Error: command BOX-LIST failed dsync-local(vmail): Error: Worker server's mailbox iteration failed The mail user doesn't yet exist on the destination yet, thus the use of the mail_home parameter. I found a mailing list message where a person was having a similar problem but I couldn't find confirmation that the issue was resolved. In our case, the backup goes from maildir to mdbox format (we can't to convert to mdbox). Things seemed to be moving along, but there are quite a few examples of dsync failing. I think the issue happens more often with large mailboxes ( > 50GB ). We're running version 2.0.13. doveconf -n: # 2.0.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-274.12.1.el5 x86_64 CentOS release 5.7 (Final) auth_mechanisms = plain login default_client_limit = 15000 default_process_limit = 10000 disable_plaintext_auth = no listen = * mail_gid = vmail mail_location = maildir:~/Maildir mail_plugins = zlib mail_uid = vmail mmap_disable = yes namespace { inbox = yes location = prefix = INBOX. separator = . } passdb { args = /etc/dovecot/conf.d/dovecot-sql.conf.ext driver = sql } plugin { zlib_save = gz } protocols = imap pop3 service auth { client_limit = 10000 unix_listener auth-userdb { mode = 0666 } } service imap-postlogin { executable = script-login /usr/bin/postlogin-imap.sh user = $default_internal_user } service imap { drop_priv_before_exec = yes executable = imap process_limit = 10000 } service pop3-postlogin { executable = script-login /usr/bin/postlogin-pop.sh user = $default_internal_user } } service pop3 { drop_priv_before_exec = yes executable = pop3 process_limit = 2500 } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = prefetch } userdb { args = /etc/dovecot/conf.d/dovecot-sql.conf.ext driver = sql } protocol lmtp { mail_plugins = zlib } protocol lda { mail_plugins = zlib } protocol imap { mail_max_userip_connections = 100 mail_plugins = zlib } protocol pop3 { mail_max_userip_connections = 30 mail_plugins = zlib } ...Jeff

[Dovecot] specifying home/sieve/sieve_dir relative to mail_location
by Edgar Fuß 25 Jun '12

25 Jun '12

With 1.2, is it possible to specify home, sieve and sieve_dir relative to mail_location? I have mail_location = maildir:/import/mail/%n/:INDEX=/var/db/dovecot/indexes/%n and, in the plugin section, home = /import/mail/%n/home sieve = /import/mail/%n/dovecot.sieve sieve_dir = /import/mail/%n/sieve I would like to partially move users to another location (different file server) by using an LDAP entry. I know it's possible to specify everything relative to home, so I could probably use relative ~/../-type paths for mail_locatin etc., but that looks a bit awkward. The VirtualUsers/Home Wiki enty contains an example for relative paths user_attrs = .., mailDirectory=home=/var/vmail/%$ which I do not understand.

[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? Thanks in advance -Christian Rößner --- Roessner-Network-Solutions Bachelor of Science Informatik Nahrungsberg 81, 35390 Gießen F: +49 641 5879091, M: +49 176 93118939 USt-IdNr.: DE225643613 http://www.roessner-network-solutions.com

[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.

[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
