[Dovecot] Dovecot, Postfix and SMTP AUTH....
by Bartosz Toczek 13 May '07

13 May '07

Hello. I've notice a problem with SMTP AUTH in postfix with dovecot. My configuration is based on Postgresql. I've created a function in postgresql which returns password and username and attached it to password_query. Query looks like this password_query = SELECT username_out as username, password_out as password FROM get_password(lower('%n'),lower('%d')); Problem is when get_password returns something like this... vmail=# SELECT username_out as username, password_out FROM get_password(lower(''),lower('')); LOG: statement: SELECT username_out as username, password_out FROM get_password(lower(''),lower('')); LOG: duration: 2.342 ms statement: SELECT username_out as username, password_out FROM get_password(lower(''),lower('')); username | password_out ----------+-------------- | (1 row) It returns 1 empty row.... When this is attached to postfix with smtp auth with such configuration # SMTP AUTH broken_sasl_auth_clients = yes smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous smtpd_sasl_authenticated_header = yes smtpd_sasl_local_domain = smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth my serwer starts to be open relay... I now that it returns empty string for username and password... so where is the password checked... if I dont send password as a parameter to my function. Definition of the function looks like this: CREATE FUNCTION get_password("login" character varying, "domain" character varying, OUT username_out character varying, OUT password_out character varying) RETURNS record Can you help with that...

[Dovecot] Public folders using NAMESPACE
by Joakim Ryden 13 May '07

13 May '07

Howdy folks! I've been trying to research how to (or if possible at all) implement public folders using the namespace feature on a server with multiple virtual domains. After about an hour of looking around I'm a little confused. :) I guess there are two questions: 1) Is it possible / does it work? 2) If yes, does anyone have a sample configuration or write-up of How You Did It[TM] to share? I've been mainly focusing on the thread from here: http://www.dovecot.org/list/dovecot/2006-June/013683.html and the wiki ACL documentation: http://wiki.dovecot.org/ACL but I'm having a hard time piecing it all together... Thanks for any and all tips! --Jo

[Dovecot] mailquota in ldap attribute 'mailQuota'
by Shahmat Dahlan 13 May '07

13 May '07

I've tried having the ldap quota in an ldap attribute, which still doesn't work. /etc/dovecot.conf protocols = imap pop3 mail_location = maildir:/data/mail/%u/Maildir protocol imap { mail_plugins = quota imapquota } plugin { quota = maildir:ignore=Trash } the rest are defaults added an attribute 'mailQuota' with value '10240' kbytes or 10Mbytes as for /etc/dovecot-ldap.conf user_attrs = mail,homeDirectory=home,uidNumber=uid,gidNumber=gid,quotaStorage=mailQuota Would appreciate if anyone could assist on this. I'd prefer to use the above than setting the mail quota manually: quota = maildir:storage=10240:ignore=Trash We are actually in the planning stage of migrating all of current our mailboxes from Netscape to Dovecot, instead of upgrading it to those new Sun.

[Dovecot] Deferring, instead of rejecting, messages when at quota
by Mike Brudenell 13 May '07

13 May '07

Greetings - I'm having trouble working out where to alter this behaviour (so please forgive me if it turns out to be an Exim thing rather than Dovecot!)... My test service is using Exim as the MTA and Dovecot's "deliver" for the LDA. We are using Maildir mailboxes with filestore quotas. When I send a large test message to myself that cannot be delivered because I don't have sufficient available quota remaining an error message is immediately returned to the sender and the incoming message discarded. The error message says this: Your message was automatically rejected by Dovecot Mail Delivery Agent. The following reason was given: Not enough disk space Instead of Exim rejecting the incoming message and generating the error response because of deliver's failure to, umm, deliver I'd like the message to be retained in Exim's queue so that it can be retried periodically. With our old/live system (Sendmail + UW IMAP's "tmail" LDA) I edited the tmail source code to return a different exit code: one that caused Sendmail to defer (re-queue) the message rather than reject it. How do I achieve this effect with Exim + deliver please? Is it a case of: * Setting something in Dovecot's configuration file (I can't spot what!); * Changing a return code in deliver's source (if so, whereabouts and to what?); * Or is there an Exim directive I need to add to the transport definition in its configuration file?

[Dovecot] wierd ssl-parameters.dat regeneration error
by Kyle Wheeler 13 May '07

13 May '07

I just had a strange problem with my Dovecot 1.0 installation. After about two weeks, it logged these messages: dovecot: Error: ssl-build-param: rename(/usr/local/var/lib/dovecot/ssl-parameters.dat.tmp, /usr/local/var/lib/dovecot/ssl-parameters.dat) failed: No such file or directory dovecot: Error: child 30689 (ssl-build-param) returned error 89 And thereafter, all login attempts resulted in this: dovecot: Error: imap-login: read(ssl-parameters.dat) failed: Unexpected EOF dovecot: Error: child 19036 (login) returned error 89 Thankfully, deleting the ssl-parameters.dat file (/var/run/dovecot/memoryhole.net/login/ssl-parameters.dat) and restarting dovecot fixed the problem, but it seems odd to me that dovecot expects /usr/local/var/lib/dovecot to exist (because, of course, it doesn't). I'm not defining that directory in the config file anywhere. Does anyone have any idea what's going on? ~Kyle -- I'm sick of following my dreams. I'm just going to ask them where they're going and hook up with them later. -- Mitch Hedberg

[Dovecot] Mailbox creation with Spam
by Master Abi 13 May '07

13 May '07

Hi all, I got dovecot working, but I would like to know when and what creates the mailbox (cur, new, trash, etc ). I noticed that when a client connects for the first time that mailbox is created or when a mail arrives for the first time (i think). I would like to give each mailbox a Spam folder, and possibly doing this automatically. Is this possible with some dovecot setting and not via scripting. Thanks master

[Dovecot] fs quota plugin and NFS
by Nicolas STRANSKY 13 May '07

13 May '07

Hi, I'm trying to use the Dovecot v1 fs quota plugin. The server uses NFS mounted volumes for INBOX and other maildir folders. The /usr/bin/quota command is working seamlessly but I get errors with the quota plugin, which gives the following logs: Apr 19 17:46:15 rouge dovecot: IMAP(xyxyxyx): quotactl(Q_GETQUOTA, nfs.xxx.yyy.org:/home) failed: No such file or directory Apr 19 17:46:18 rouge dovecot: IMAP(yxyxyxy): quotactl(Q_GETQUOTA, nfs.xxx.yyy.org:/home) failed: No such file or directory Is there a way to get it work ?

[Dovecot] Migrating to Maildir -> path
by Wouter de Jong 13 May '07

13 May '07

Hello, I'm in the process of migrating to Maildir, and I wondered what would be an acceptable path. I want to do virtual-accounts only, so $HOME/Maildir/ is not an option. I was thinking of /some/path/username(a)domain.tld/Maildir/ and later perhaps /some/path/(firstletter)/username(a)domain.tld/Maildir/ but perhaps Maildir/ is a bit too redundant here.... Anyone who could advice ? Many thanks, Wouter

[Dovecot] Mixing MBOX and Maildir?
by Marc Perkel 13 May '07

13 May '07

Is it possible to have some folders be mbox and some be maildir format? Why you might ask? Sometime for diagnostics I have the Exim MTA archive certain messages in MBOX format and then I want to copy them into an imao folder to look at them with Thunderbird. When I used MBOX all I had to do was copy the file into a folder and it worked. So what I'd like to do is have a folder with a special name that is MBOX and the rest be maildir. Ideally have Dovecot be smart so that if the file exists then it is assumed to be MBOX and if the directory exists then it is assumed to be maildir. Has anyone done anything like this?
