Hi list! I'm always trying to configure Dovecot to ask our LDAP-Server (AD) in order to authenticate the users. I really don'know what can I do wrong... I configured my Dovecot so: hosts = chimaera.company.local dn = CN=mailproxy,CN=Users,DC=company,DC=local dnpass = SECRET sasl_bind = no tls = no debug_level = -1 auth_bind = yes ldap_version = 3 base = dc=company,dc=local deref = never scope = subtree user_filter = (&(sAMAccountName=%n)(objectClass=user)) pass_attrs = userPassword=password pass_filter = (&(samAccountName=%n)(objectClass=user)) default_pass_scheme = CRYPT If I try to login in, with my login and password, I see with ngrep that Dovecot ask the AD for my data AND GET THEM, then I see: T 10.0.46.4:49204 -> 192.168.168.23:389 [AP] 0p...ck."DC=DomainDnsZones,DC=company,DC=local................4....samAccountName..bertoncello....objectClass..user0. # T 192.168.168.23:389 -> 10.0.46.4:49204 [AP] 0........e................000004DC: LdapErr: DSID-0C0906E8, comment: In order to perform this operation a successful bind must be completed on the connection., data 0, v1db1.

To say that disabling the use of index files solved your problems is akin to saying amputating your foot solved your bunion problems. Ordinarily, indices ought to be a benefit -- it will help with I/O bottlenecks when mailboxes or number of users get huge. I can't tell from your list of problems whether they are the result of one or many causes, but fixing the index consistency problem would go a long way toward clearing up most of your problems. If INDEX=MEMORY is working for you and you don't see performance degradation, there's no harm in using it, but in my opinion, it may benefit you in the future to get to the bottom of the indexing problem rather than to lop it off altogether. > I am curious if setting INDEX=MEMORY "disables the index completely" as > per http://wiki2.dovecot.org/MailLocation: "If you really want to, you > can also disable the index files completely by appending > :INDEX=MEMORY." Or if there are index files in memory as one might > assume taking the directive literally, and if so, if these are > functionally equivalent to, say, Courier IMAP's caching model. The latter I believe. The important words in the wiki sentence is "index files", not "indexing". Dovecot is still indexing, exept that it builds it from scratch each and every time a worker process accesses a mailbox, so incurs a fixed overhead that cannot be used for the next session.

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
