[Dovecot] Public Namespace and ACLs with pure virtual users
by Marc Delling 27 Jun '07

27 Jun '07

hi! i would appreciate to have some comments on my below scenario: # from the config userdb static { args = uid=vmail gid=mail home=/vmail/%d/%n } namespace public { separator = / prefix = All/ location = maildir:/vmail/%d/all/Maildir:CONTROL=~/Maildir/control/ all:INDEX=~/Maildir/index/all inbox = no hidden = no } namespace private { separator = / prefix = location = maildir:~/Maildir inbox = yes hidden = no } # end config the public namespace is also the maildir of the user "all@mydomain". a sieve skript is dropping mail for all@mydomain to the appropriate maildir within this maildir/namespace (e.g. .Support/) first of all: this works to some point but is such a configuration valid? can a public namespace be the maildir of a user? if a new mail for all@mydomain comes in, all subscribed users (of this domain) can view it and it is marked as /Seen individually. the important feature to me: the /Seen flags are managed per user as configured in the public namespace now the problem: the whole mail system runs with one uid/gid and virtual users, which has the effect that some user can delete mails in the public namespace or drop mails into it, create folders etc. this is not wanted. i wanted a read-only public namespace. so i decided to use acls. as namespace prefixes are ignored i needed to create them globally. my first try was: /etc/dovecot/acls/Support: owner lrwstiekxa authenticated lr which lead to the result that other users than all@mydomain cannot manipulate the public namespace at all, including setting their /Seen flag. that was the first surprise to me as i thought this flag would be managed seperately in the users homes. after a (very short) thought i came to this (allow setting the /Seen flag for others): owner lrwstiekxa authenticated lrs which lead to another unexpected result: the /Seen flag is now set globally. if one user marks a mail /Seen, it is /Seen for all other users too. where is the problem? except for the iso/osi layer 8 problem i am aware of... marc

[Dovecot] set maildir and directory default for deliver?
by Mark Edwards 26 Jun '07

26 Jun '07

I asked this question in a more detailed post, with no response, so I'm going to ask point blank. Is there a way make dovecot's deliver use default mailbox and directory settings? I'm thinking of the mail_location parameter, which deliver seems to ignore. Thanks! -- Mark Edwards

[Dovecot] APPEND fails
by Dirk Müller 26 Jun '07

26 Jun '07

hi list, i wrote a small tool in java which transfers all mails from one imap-server account to another imap-server account using the javax.mail API. when i use cyrus as source and destination imap server everything is fine. when i use dovecot as destination server occasionally exceptions occur when appending the mails. i was not able to see what's really going wrong so i used wireshark to get the imap command that fails: A23 APPEND INBOX.MYSUBFOLDER () "14-Mar-2007 14:20:45 +0100" {0+} A23 NO Append aborted. this is easy to check via telnet, always the same error. i'm not sure why the javax.mail API uses the "{0+}" but somehow it occurs every now and then. sending this command to a cyrus imap server does not fail. any idea? is this a javax.mail problem? thanks and best regards, dirk

I read this documentation about Authentication and Logging debuggind. I add : auth_debug=yes auth_debug_passwords=yes --------------------------- for this test, I change my password = "MyPasswd" (and I change again after) My client is Thunderbird on Ubuntu 7.04 in /var/log/syslog dovecot: auth(default): client in: AUTH^I1^IPLAIN^Iservice=IMAP^Isecured^Ilip=87.98.98.98^Irip=212.71.11.157 dovecot: auth(default): client out: CONT^I1^I dovecot: auth(default): client in: CONT^I1^IAGRpZGllcgBNeVBhc3N3ZA== dovecot: auth(default): passwd(didier,212.71.11.157): password mismatch dovecot: auth(default): client out: FAIL^I1^Iuser=didier I try to check myself : printf 'didier\didier\MyPasswd' | mmencode ZGlkaWVyXGRpZGllclxNeVBhc3N3ZA== The end seem to be the same...

[Dovecot] Setting retention policies
by Don Russell 25 Jun '07

25 Jun '07

I access e-mail from different PCs, typically using Thunderbird e-mail client. Thunderbird has a a "retention policy" it can set on a folder by folder basis. Policies such as how long to keep messages for, or how many messages to keep. Is there a way to set those policies on the server itself? Thank you

[Dovecot] Quota from passdb sql
by Bruno Puga 25 Jun '07

25 Jun '07

Hello folks! Is it possible to retrieve quota information from a passdb sql lookup and using static userdb? I've tried here without success, and I can't find in the wiki or forum. Some ways I configured dovecot-sql.conf: 1) password_query = SELECT email AS user, CONCAT('maildir:storage=',quota) AS quota, password FROM users WHERE email = '%u' 2) password_query = SELECT email AS user, CONCAT('maildir:storage=',quota) AS userdb_quota, password FROM users WHERE email = '%u' With userdb sql things worked perfect, but as I can use static userdb I just need quota information per user from passwd sql. Thanks, Bruno.

[Dovecot] quota calculating
by Scott Zahn 25 Jun '07

25 Jun '07

Hey everyone, Currently where I work we use qmail. Every time a message is delivered, qmail seems to walk through the user's entire maildir in order to calculate quota usage. Delivering messages simultaneously to just a few users who are allowed large maildirs (1-2GB) will bring our servers to their knees. Which brings me to dovecot. I use dovecot whereever I can, but haven't yet needed to set up quotas. I would like to migrate my servers at work to use dovecot, but have a few questions regarding quotas. Could someone explain how dovecot calculates quota usage on mail delivery? Also, is there anyone here on the list that uses quoatas on large maildirs (>=2GB)? How well has it worked for you? thanks, Scott

[Dovecot] LIST % not returning correct data?
by J.Wendland＠scan-plus.de 25 Jun '07

25 Jun '07

Hi list, I have namespace private { prefix = INBOX. separator = . inbox = yes } in an installation migrated from courier. I am testing with Outlook Mobile 5 (OM) which uses 'LIST "" %' to get the folder list. Now courier used to return * LIST (\HasChildren) "." "INBOX" whereas dovecot returns * LIST (\HasNoChildren) "." "INBOX" which is why OM failes to display any folder. Is this dovecot's failure or am I missing something here?
