Dovecot as Proxy for __MORE__ Exchange-Servers
by Luca Bertoncello 22 Jun '15

22 Jun '15

Hi list! I'm trying to configure Dovecot 2.2.18 to act as proxy. Dovecot has to authentificate the users against an LDAP-Server (AD) and then act as IMAP-Proxy to an Exchange Server. Now the problem is, that we have TWO Exchange servers (and two ADs, too). How can I say to Dovecot that it has to search for the user in the first AD (and if found proxy to the first Exchange server) and if the user was not found, to search in the second AD (and if found proxy to the second Exchange server)? Thanks a lot Luca Bertoncello (lucabert(a)lucabert.de)

Quota SQL separate queries?
by Akos Vandra 22 Jun '15

22 Jun '15

Hello, We are trying to enforce per-domain quotas. Currently my quota-sql.conf looks like this: connect = host=/var/run/postgresql dbname=mail user=mailreader 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 quota = dict:Domain:%d:proxy::sqlquota This works with a trigger by updating and , however I am unable to show the administrators a list of which of their users are using the most space. That is to be purely informative, and is not to be enforced. I would appreciate if there was a documented way to specify exact SQL queries to run for inserting, updating and selecting from the quota storage, something like this: -- CREATE VIEW quota_domain AS SELECT domain, sum(bytes), sum(messages) FROM quotas GROUP BY domain INSERT/UPDATE INTO quotas(username, domain, bytes, messages) SELECT bytes, messages from quota_domain WHERE domain = %d Is there such a possibility? If not, can you suggest a workaround to have a list of per-user quota usages as well as enforced per-domain quotas? Thanks, Akos Vandra

Mailbox aliases problem
by azurIt 22 Jun '15

22 Jun '15

Hi, i'm trying to implement malbox aliases but it's not fully working as i expected. This is my configuration: mail_plugins = acl mailbox_alias plugin { mailbox_alias_old = INBOX/Odoslane mailbox_alias_new = INBOX/SentTest } That 'INBOX/' must be there because of this (we were moving from Courier IMAP): namespace inbox { type = private prefix = INBOX/ separator = / inbox = yes list = yes } All of this is working fine, if i create folder SentTest, the link to folder Odoslane is correctly created on filesystem. The problem is that folder SentTest is invisible even after creation: 1 CREATE "INBOX/SentTest" 1 OK Create completed. 2 LIST "" "*" <all folders except SentTest are listed> 2 OK List completed. 3 LIST "INBOX/SentTest" "*" 3 OK List completed. 4 LIST "INBOX/Odoslane" "*" 4 LIST (\HasNoChildren \Sent) "/" INBOX/Odoslane 4 OK List completed. 5 CREATE "INBOX/SentTest" 5 NO [ALREADYEXISTS] Mailbox already exists 6 DELETE "INBOX/SentTest" 6 OK Delete completed. None of the e-mail clients i tried can see the folder. I'm using Dovecot 2.2.13 from Debian Wheezy (wheezy-backports). Any hints? azur

setting quota through IMAP
by Daniel Tröder 22 Jun '15

22 Jun '15

I'd like to set the quota of a user through the IMAP protocol. I use Pythons imaplib: imap.setquota("test1m(a)uni.dtr", "(storage 8192)") ('NO', ['Quota can be changed only by admin.']) So... which user is the "admin" user in a virtual user setting (passwd: PAM, userdb: LDAP)? Greetings Daniel

how do I conceptualize system & virtual users?
by lejeczek 22 Jun '15

22 Jun '15

I guess this would be a common case, I am hoping for some final clarification. a few Linux boxes share ldap (multi-master) backend that PAM/SSSD uses to authenticated users, and these LDAPs are also is used by Samba, users start @ uid 1000. Boxes are in the same both DNS and Samba domains. Do I treat these users as system or virtual users from postfix/dovecot perspective? If it can be a matter of choice then which is better/best? many thanks.

The first bonehead maneuver seems to be: location = virtual:/var/mail/%%d/%%n/mdbox/virtual I'm thinking it should be: location = virtual:/var/mail/%%d/%%n/mdbox/mailboxes/virtual But...it didn't seem to make a difference. And if I have the "virtual" folder tree under a location other than "/var/mail/domain/user/mdbox/mailboxes" no names appear - so I think I have the files in the right place.
