[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?

[Dovecot] inetd config - dovecot doesn't exits
by kjonca＠o2.pl 17 Mar '11

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

[Dovecot] Configuration of LMTP Reject Code
by Petter Urkedal 17 Mar '11

17 Mar '11

Is it possible to change the reject codes from the Dovecot LMTP agent? In particular I would like to change the "550 5.1.1 <...> User doesn't exist." to a temporary failure, since we already validate email addresses on the mail front-end, and such errors are most likely due to a temporary glitch in the user database lookup. We use Postfix on the front-end, which is very configurable in this respect. I don't see a way to override the error code from LMTP, though, but suggestions are welcome.

[Dovecot] Using dovecot with wordpress/phpass passwords?
by Joan 17 Mar '11

17 Mar '11

Good afternoon, I am trying to setup dovecot to authenticate using the userdata from wordpress. It's being a bit mor difficult than I thought. This is the relevant part of the dovecot-sql.conf default_pass_scheme = CRYPT password_query = SELECT user_pass AS password FROM wp_users WHERE user_email='%u'; user_query = SELECT 501 as uid, 501 as gid,'maildir:storage=51200' as quota FROM wp_users WHERE user_email = '%u' I can see that the query is being procecessed according to the logs. Wordpress and others are using phpass to authenticate (http://www.openwall.com/phpass/) it is basically a salted md5 hash. Basically, after the process, a hash like this is obtained. $P$BiWISc3IsqRHxeEjq4VJP1Vi8gy4mg1 (for test123 password) I would like to know if dovecot would be able to read this, otherwise I could still make a custom checkpassword function but that would be non-optimal. Could someone guide me on this? If you need more details just ask. Thanks a lot, joan

I think that I need to modify "/etc/ldap.conf" to remap some attribute with mailQuota from ldap, and then, try to catch this as arg.

[Dovecot] exim and /var/run/dovecot/auth-client permissions
by John Connett 17 Mar '11

17 Mar '11

I am attempting to configure a dovecot 2.0 + exim + fetchmail (demon) combination on openSUSE 11.4, initially with the standard dovecot package (2.0.9-3.4-x86_64) and now with the later server:mail build service package (2.0.11-1.1-x86_64). I followed the instructions in http://wiki2.dovecot.org/HowTo/EximAndDovecotSASL but despite the changes in conf.d/10-master.conf the permissions on /var/run/dovecot/auth-client remain unchanged: $ ls -l /var/run/dovecot/auth-client Srw------- 1 root root 0 Mar 14 13:11 /var/run/dovecot/auth-client $ This is probably the cause of authentication failures from exim. I suspect it is something trivial but haven't yet been able to find the answer.
