[Dovecot] Unconfigured dictionary name 'quotadict'
by Simone Caruso 17 Mar '11

17 Mar '11

Currently i'm migrating an existing dovecot 1.2 server to dovecot 2.0.11, once configured the 2.0 server works, auth works... but i get these messages in mail.log: dict: Error: dict client: Unconfigured dictionary name 'quotadict' Mar 17 16:46:14 penny dovecot: imap(mailbox(a)example.com): Error: write(/var/run/dovecot/dict) failed: Broken pipe Mar 17 16:46:38 penny dovecot: dict: Error: dict client: Unconfigured dictionary name 'quotadict' Mar 17 16:46:38 penny dovecot: imap(mailbox(a)example.com): Error: read(/var/run/dovecot/dict) failed: Remote disconnected My quota configuration is the following (as wiki says): service dict { unix_listener dict { mode = 0600 user = vmail } } plugin { quota = dict:User quota::proxy::quotadict quota_rule2 = Trash:storage=+55M } dict { quota = mysql:/etc/dovecot/dovecot-dict-sql.conf } dovect-dict-sql.conf: connect = host=localhost dbname=ketna user=***** password=***** map { pattern = priv/quota/storage table = imap_quota username_field = email value_field = current } map { pattern = priv/quota/messages table = imap_quota username_field = email value_field = messages } Someone can tell me where's my fault?

[Dovecot] Migrating to mdbox
by Chris Wilson 17 Mar '11

17 Mar '11

Hi all, I think it would be a good idea for me to move from mbox to mdbox, as I have 57,000 messages in my inbox, and clients hang for a minute whenever they request a CHECK, or Dovecot feels the need to run one itself. Looking at past threads: http://www.mail-archive.com/dovecot@dovecot.org/msg35212.html http://comments.gmane.org/gmane.mail.imap.dovecot/53936 it seems that the safest way is to run: sudo dsync -v -u chris backup mdbox:/home/chris/mdbox eliminate any errors that it reports, test the new mdbox access temporarily, and then switch my config in Dovecot. Ideally I'd like to do that just for me, without disrupting other users of this server (that I help to admin). This error occurs every time I run dsync, and I understand it, so I've elided it: dsync(chris): Error: open() failed with mbox file /home/chris/mail/admin: Permission denied dsync(chris): Error: Failed to sync mailbox admin: Internal error occurred. Refer to server log for more information.

[Dovecot] SSL Compatibility? SNI vs SAN (Subject Alternative Names) and multiple domains
by Thomas Harold 17 Mar '11

17 Mar '11

Getting ready to redo our mail server setup and I'm trying to wrap my head around the ins and outs and pratfalls involved in SSL, multiple domains, and Dovecot. I've taken a look at: http://wiki2.dovecot.org/SSL/DovecotConfiguration My basic understanding at this point is that: - With SSL for IMAP/POP3, it is limited to one certificate per IP address, because the SSL process starts as soon as the client opens the socket to the IP address. In order to support multiple domains / server names, you have to rely on SAN (Subject Alternative Names) in the server's SSL certificate. - If I use STARTTLS for IMAP/POP3 and Dovecot 2.x, then the SNI process will allow the client to specify that they want to talk to mail server XYZ and Dovecot will hand the correct certificate to the client. However, a lot of devices don't support SNI yet so this is fraught with peril and incompatibilities. So it seems like if I have fewer IP addresses then mail server names, I should stick with a single SSL cert and use SANs. (Wildcard certs are not an option due to the top level domain being different.) How big of an issue is a cert with half a dozen or a dozen SANs attached? Do most mail clients handle that sort of certificate properly in order to access their mailboxes? Reference links: http://www.digicert.com/subject-alternative-name-compatibility.htm

[Dovecot] problems with public (sub)folders

Hi, i am trying to share a maildir++ mailbox to other users but i can only subscribe to the root directory. The subfolders of the public mailbox do not appear in the exported list.

[Dovecot] dict crashes with multiple map definitions
by Birger Brunswiek 17 Mar '11

17 Mar '11

Hi, I get a crash in dict if I use multiple map sections. Each one of them works fine by their own. I managed to convince dovecot to create dump files to debug this, but I can't figure out how to do the same for dict. How can I do this? Anyway, perhaps someone already know's what's wrong by looking at what I do in the sql dict configuration.

[Dovecot] dovecot 1.2 quota with local users
by iti＠promax.media.pl 17 Mar '11

17 Mar '11

Hello, I got problem with setting quota from mysql for local users. In database are only information with quota. Password are store in passwd/shadow. My database have only simple info like in wiki description. Table created with: CREATE TABLE quota ( username varchar(100) not null, bytes bigint not null default 0, messages integer not null default 0, primary key (username) ); In dovecot.conf like in description is: dict { quotadict = mysql:/etc/dovecot-dict-sql.conf } plugin { # v1.2 + SQL: quota = dict:user::proxy::quotadict # v1.2 + file: quota = dict:user::file:%h/Maildir/dovecot-quota quota_rule = *:storage=10M:messages=1000 } File dovecot-dict-sql.conf has: # v1.2+ only: connect = host=localhost dbname=mails user=sqluser password=sqlpass map { pattern = priv/quota/storage table = quota username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota username_field = username value_field = messages } With corrected values about databasename, user and password. Where should to add information about sql query when autorization is not via myqsl (only shadow/password). There are in description info about additional file with user_query: dovecot-mysql.conf. Can anybody know how it should it look like and where to add it in config?

Is there any option for dovecot to exit when is unneded? I mostly use dovecot via shell process (ie. something like /usr/sbin/dovecot --exec-mail imap) But sometimes I want to use it remotely via tcp and I run dovecot via inetd. --8<---------------cut here---------------start------------->8--- localhost:imap stream tcp nowait root /usr/sbin/tcpd /usr/lib/dovecot/imap-login --8<---------------cut here---------------end--------------->8--- in inetd.conf works good, but dovecot stays, even if all clients ended their connections. How can I make dovecot to exit after last client disconnects?

[Dovecot] Attachment file size error in SIS
by Daniel L. Miller 17 Mar '11

17 Mar '11

I've got an attachment that triggers a "smaller than expected" error. It was a pdf I received some time ago. I copied the file from the dovecot storage, renamed it to something close to the original name (I don't remember what that was), then created a new mail with this as an attachment and saved it to the server. This created a new file, identical file size to the other - but continues to have the "smaller than expected" error. -- Daniel
