[Dovecot] Driving quota out of a database.
by David Craigon 06 Mar '07

06 Mar '07

Hi there, I'm using postgres as a userdb for dovecot. I'm am trying to get the quota plugin to work. I have a column in my table that returns the quota in KB. I am using the postgres expression "('maildir:storage=' || mailstore_control.mailbox.quota) AS quota" as recommended in the manuals. This expression is NULL to start with, which I take to mean unlimited quota. Trouble is, if I change it to a value, and then change it back to null, I don't seem to go back to unlimited quota. I'm using maildir++ quotas. What gives? :-) David Griffin Information Systems Ltd 20 St Christopher's Way, Pride Park, Derby DE24 8JY www.griffin.com <http://www.griffin.com/> Registered in England and Wales.

[Dovecot] Replacing qmail + vpopmail with: sendmail + dovecot
by Oliver Schulze L. 06 Mar '07

06 Mar '07

Hi, I wonder if it posible to replace qmail + vpopmail with sendmail + dovecot? The idea is like this: - use sendmail + milter API to filter spam/virus and deliver the email to the dovevot MDA (LDA) - dovecot should save the email to the directory as specified in the vpopmail DB - maintain the vpopmail BD (users + passwd) - use dovecot pop3/imap for the clients - use sendmail again to receive the email from the pop3/imap users and deliver the email to the internet as usual. Anyone has done this? It is posible in the paper, in the real world? many thanks Oliver -- Oliver Schulze L. | Get my e-mail after a captcha in: Asuncion - Paraguay | http://tinymailto.com/oliver

[Dovecot] MBOX to MAILDIR conversion
by Marc Perkel 05 Mar '07

05 Mar '07

Thinking about going from mbox to maildir. Started with mbox way back when but thinking about making the conversion. The main reason is that I use rsync for backups and when these huge mailboxes are touched I have to copy the whole thing. With maildir I only copy the files that change. So - my questions is - what's the easiest way to make this happan. I assume there are conversion utilities. I'm using Exim as an MTA. Also - using Ext3 for the file system on a Raid 10 array. Backup server will run Ext3 Raid 1. Is the number of files in one directory going to be a problem? And - any tip/tricks would be appreciated. Things to look out for? Still in planning stage. Thanks in Advance.

Not quite sure where the docs are on Dovecot deliver. Went to the wiki and it left me confused. The docs there definitely need some work. Anyone have some examples to share?

Hello folks -- I'm using Debian etch and I've got Mysql 5.0, Dovecot 1.0rc15 and DSpam 3.6.8... I've downloaded the mysql-dspam-plugin code, and it builds without errors. But when trying to start Dovecot I get: Starting mail server: dovecotIEffective uid=65534, gid=65534 ILoading modules from directory: /usr/lib/dovecot/modules/imap Emodule /usr/lib/dovecot/modules/imap/lib_dspam.so: dlsym(dspam_init) failed: /usr/lib/dovecot/modules/imap/lib_dspam.so: undefined symbol: dspam_init Error: imap dump-capability process returned 89 Any help with how to fix this would be great! I'm not really a programmer so I'm not quite sure where to look... thanks!! Rob Klingsten

[Dovecot] Dovecot ignoring Quotas
by Frank Doege 03 Mar '07

03 Mar '07

Hi, i have installed the dovecot 1.0rc25 and everything is working well. I have connected it to a postgresql database. Now to my little problem: Postfix is delivering into a maildir folder with active maildirquota patches, and this is working well. The problem is only that dovecot is not recognizing the maildirquota file at all. I have configured it as in the documentation with Plugin { Quota=maildir } Anyone any idea ? maybe this is a bug ? Thanks

[Dovecot] Using auth_bind_userdn causes uid to be improper case
by Aaron Luchko 02 Mar '07

02 Mar '07

I'm having a problem with dovecot-1.0-1.1.rc15.fc6 + LDAP + auth_bind_userdb. I have the following /etc/dovecot.conf: mail_location = maildir:/var/spool/mail/%u/ protocols = imap pop3 mail_log_prefix = "%Us(%u):%i:%h " first_valid_uid = 5001 first_valid_gid = 5001 protocol imap { } protocol pop3 { } protocol lda { postmaster_address = postmaster(a)example.com } auth_verbose = yes auth_debug = yes auth default { mechanisms = plain userdb ldap { args = /etc/dovecot-ldap.conf } passdb ldap { args = /etc/dovecot-ldap.conf } user = root } dict { } plugin { } and /etc/dovecot-ldap.conf: hosts = driveable.example.com base = dc=example,dc=com #dn = cn=Directory Manager #dnpass = password auth_bind_userdn = uid=%u, ou=People, dc=example, dc=com uris = ldap://127.0.0.1 user_attrs = mail user_filter = uid=%u user_global_uid = 5001 user_global_gid = 5001 pass_filter = uid=%u The problem is that if we have an entry in LDAP, User Name, with the uid UName, postfix stores the users mail in /var/spool/mail/UName If I log into dovecot using uname (LDAP uid isn't case sensitive) than dovecot tries to look in /var/spool/mail/uname, similarly if I log in with unAME dovecot will look in /var/spool/unAME. However, if instead of using auth_bind_userdn = uid=%u, ou=People, dc=example, dc=com I bind with dn = cn=Directory Manager dnpass = password than it correctly looks in /var/spool/UName regardless of the case used when logging in. It seems like when I log in with auth_bind_userdn %u is being left as the value I logged in with rather than being reloaded from LDAP. I was wondering if I have made some mistake in the configuration files to cause this behaviour or if something else is going on? thanks, Aaron
