[Dovecot] Namespace subscription issue
by Brad Davidson 02 Nov '10

02 Nov '10

I'm a little confused about how public namespaces work with subscriptions. If I set subscriptions=no and subscribe to the folders, the subscription entries go into the user's private subscription file and that's fine. However, I am unable to pull their status with the LIST-EXTENDED extension. Normal listing works OK: A0004 LIST "" "*" RETURN (STATUS (MESSAGES UNSEEN)) * LIST (\NonExistent) "/" "Public" * LIST () "/" "Public/Public One" * STATUS "Public/Public One" (MESSAGES 0 UNSEEN 0) * LIST () "/" "Public/Public One/Sub 1" * STATUS "Public/Public One/Sub 1" (MESSAGES 0 UNSEEN 0) * LIST () "/" "Public/Public One/Sub 2" * STATUS "Public/Public One/Sub 2" (MESSAGES 0 UNSEEN 0) * LIST () "/" "Public/Public Two" * STATUS "Public/Public Two" (MESSAGES 0 UNSEEN 0) * LIST () "/" "Public/Read-only" * STATUS "Public/Read-only" (MESSAGES 1 UNSEEN 0) A0004 OK List completed. Listing SUBSCRIBED (or LSUB) fails: A0003 LIST (SUBSCRIBED) "" "*" RETURN (STATUS (MESSAGES UNSEEN)) * LIST (\Subscribed) "/" "Public/Public One" * NO Mailbox doesn't exist: Public.Public One * LIST (\Subscribed) "/" "Public/Public One/Sub 1" * NO Mailbox doesn't exist: Public.Public One.Sub 1 * LIST (\Subscribed) "/" "Public/Public One/Sub 2" * NO Mailbox doesn't exist: Public.Public One.Sub 2 * LIST (\Subscribed) "/" "Public/Public Two" * NO Mailbox doesn't exist: Public.Public Two * LIST (\Subscribed) "/" "Public/Read-only" * NO Mailbox doesn't exist: Public.Read-only A0003 OK List completed. If I set subscriptions=yes it works OK, but then the subscriptions are shared unless I override SUBSCRIPTIONS in the mail location. Is this working as designed? Here's what I ended up doing - is there a better way? namespace { inbox = yes location = prefix = separator = / type = private } namespace { hidden = yes list = no location = maildir:%h/Maildir prefix = ~/mail/ separator = / type = private } namespace { type = public separator = / prefix = Public/ location = maildir:/var/mail/public:INDEX=~/Maildir/public:SUBSCRIPTIONS=~/Maildir/ public/subscriptions subscriptions = yes } --- Brandon 'Brad' Davidson Virtualization Systems Administrator University of Oregon Information Services (541) 346-8098 brandond(a)uoregon.edu

[Dovecot] What causes the quota information to get updated?
by Patrick Westenberg 02 Nov '10

02 Nov '10

Hello, if new mails arrive, the quota information is updated and reported via imap immediately. However, after deleting a message, nothing happens. Even if I delete all messages and the mailbox e.g. was over quota, new mails won´t be accepted because the mailbox is over quota. Is this the way it should be or a misconfiguration? # 2.0.4: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-amd64 x86_64 Debian 5.0.5 auth_mechanisms = plain login log_timestamp = "%Y-%m-%d %H:%M:%S " mail_debug = yes mail_gid = vmail mail_location = mdbox:~/mdbox mail_plugins = quota mail_uid = vmail managesieve_notify_capability = mailto managesieve_sieve_capability = comparator-i;octet comparator-i;ascii-casemap fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date namespace { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { quota = dict:User quota::file:%h/mdbox/dovecot-quota quota_rule2 = INBOX.Trash:storage=+50M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=5%% quota-warning 5 %u sieve = ~/.dovecot.sieve sieve_global_path = /usr/local/etc/dovecot/sieve/default.sieve } protocols = imap sieve service imap-login { service_count = 1 } service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieve_deprecated { port = 2000 } service_count = 1 } ssl = required ssl_cert = </etc/ssl/certs/imap_wk-serv_net.crt ssl_key = </etc/ssl/certs/imap_wk-serv_net.key userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol imap { mail_plugins = $mail_plugins imap_quota }

[Dovecot] LDAP acl_groups - can multivalue LDAP be used
by ian+dovecot＠comtek.co.uk 02 Nov '10

02 Nov '10

Hi, Is there some kind of way to get acl_groups out of LDAP without having to maintain an entry with a list of groups 'a,b,c' and so on? Our groups have a list of 'member' attributes with CNs pointing at users. Ideally there would be a way to look this up directly. Alternately I could perhaps use an OpenLDAP overlay to show 'group' attributes for each user's ldap entry. I would then like to be able to tell it to get all 'group' attributes and comma-separate them. The best option I've seen so far is something like http://www.dovecot.org/list/dovecot/2010-March/047731.html which seems to involve a completely separate LDAP session from a login script. Thanks in advance for any help, Ian

[Dovecot] problem with folder creation
by John Watson 02 Nov '10

02 Nov '10

I am running dovecot 1.2.12 on Free BSD 8.1. We also have postfix and a version of squirrelmail for the UI. We are using MySql database to store the email account info. I wrote a script to insert about 100K users into mysql. Those accounts seem to work well and I'm able to see things like 'Drafts', 'Trash' and 'Sent'. Now I am working on code to create new accounts - one at a time. The accounts get created and I can send and receive email from them but when I go go Drafts, Sent or Trash I get an error that says: ERROR: Could not complete request. Query: SELECT "INBOX.Drafts" Reason Given: Mailbox doesn't exist: INBOX.Drafts When I go out and look at the mailbox folders for these users I only see "cur", "new", and "tmp" whereas on other accounts that work well I also see things like INBOX.Drafts etc. I have examined the sql that is inserting the accounts in bulk versus the one by one case and can not see any differences (other than a new mailbox name/password etc). Everything that I'm reading online indicates that Dovecot should just create these extra folders on the server and there is really nothing for either an admin or a user to do. Does anyone have any more information on this? Thanks in Advance John Watson

[Dovecot] Doveadm-Expunge v2.0.5
by Kui Zhang 02 Nov '10

02 Nov '10

Hello Few questions regarding Doveadm-Expunge. 1. I have lazy expunge configure with this name space: .EXPUNGED Storage type: mdbox doveadm -Dv expunge -u user@domain mailbox ".EXPUNGED/*" savedbefore 7d I get some interesting outputs. doveadm(user@domain): Debug: expunge: box=.EXPUNGED/INBOX/mon uid=791 doveadm(user@domain): Debug: expunge: box=.EXPUNGED/INBOX/mon uid=792 doveadm(user@domain): Debug: expunge: box=.EXPUNGED/INBOX/mon uid=793 .... doveadm(user@domain): Info: expunge: box=INBOX/mon, uid=196, msgid=<E1OwJm4-0000j4-1l@domain>, size=1856 doveadm(user@domain): Info: expunge: box=INBOX/mon, uid=197, msgid=<E1OwJmP-0000pr-4M@domain>, size=1756 doveadm(user@domain): Info: expunge: box=INBOX/mon, uid=198, msgid=<E1OwJpP-0002Hp-Pu@domain>, size=1810 doveadm(user@domain): Info: expunge: box=INBOX/mon, uid=199, msgid=<E1OwJqw-0002y7-AF@domain>, size=1766 doveadm(user@domain): Info: expunge: box=INBOX/mon, uid=200, msgid=<E1OwJud-0004ba-Fe@domain>, size=1890 ... So what is the diff between "Debug: expunge" and "Info: expunge". Anything done to "Info: expunge"? I am assuming the "debug: expunge" are the only entries with actions. And "Info: expunge" is not doing anything. I ran doveadm purge -u user@domain after. I did not notice any missing emails. Sorry for the trivial question, I just want to make sure not mail would disappear, all of sudden. 1.A. Would not it be faster not to enumerate for large mailboxes (30-40GB - Maildir)? Is it possible to add a switch, to select single user expunge behavior? ref: http://www.mail-archive.com/dovecot@dovecot.org/msg32322.html 2. Also. expunge does not appear to remove empty mailboxes, is this a bug or intentional? If intentional, why? Any way to automated removal of empty mailboxes? Thank you KuiZ

[Dovecot] Maildir and Index max size
by Emmanuel Gonzalez Carmona 02 Nov '10

02 Nov '10

Hi all, I was wondering if any of you had configured a Mailbox with >= 5GB of space with LDA indexing enabled on it. I'm trying to understand the limits to Dovecot (if there are any) regarding maildirs/indexes max size. Reading in the documentation i didn't found anything concerning this issue. Any experience with this? Emmanuel Gonzalez Carmona

[Dovecot] Differences between IPv4 and IPv6 authentication
by Tony Meyer 02 Nov '10

02 Nov '10

Hi, I have Dovecot listening on both IPv4 and IPv6, and can connect on both interfaces, but cannot authenticate over IPv6, using exactly the same credentials as IPv4. I assumed that the same authentication mechanisms would be used, regardless of the protocol being used - are there differences somewhere? For example: ~$ telnet server1.teststable.simplyspamfree.com 143 Trying 2a01:4f8:100:12c1:bc:28:b2:34... Connected to server1.teststable.simplyspamfree.com.
