[Dovecot] dovecot-lda not correct folder
by tony.blue.mailinglist＠gmx.de 07 Nov '12

07 Nov '12

Hello, i use dovecot with maildir. The maildir-folder looks like this: vmail/mail/user1/cur vmail/mail/user1/.Sent vmail/mail/user1/.optionalfolder Procmail should put some definded mails in the "optionalfolder" My uses configuration does not do this: ... DELIVERMAIL="/usr/lib/dovecot/dovecot-lda" IMAP="$DELIVERMAIL -e -d $LOGNAME -m INBOX" ZUSATZORDNER="$DELIVERMAIL -e -d $LOGNAME -m .optionalfolder" ... dovecot-lda puts the mails for the optionalfolder always in the .cur (INBOX). What´s the correct dovecot-lda parameter to put the mails in the optionalfolder? Thank you! Tony

[Dovecot] Auth USER lookup failed
by Angel L. Mateo 07 Nov '12

07 Nov '12

Hello, I'm running dovecot 2.1.9 and I'm trying to configure shared folders. So, as described at http://wiki2.dovecot.org/SharedMailboxes/Shared I have configured a namespace like this: namespace { type = shared separator = / prefix = shared/%%u/ location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = yes } In one user (user1) I have configured ACLs so another one (user2) has access to a folder. Now, I want to susbscribe user2 to this folder. The problem I have is that whenever I try to list folders for this user (running thunderbird client) I get a panic and an error in the dovecot server (I have attached the complete log). The error says: Nov 6 11:58:56 myotis30 dovecot: auth: Error: userdb(user1): client doesn't have lookup permissions for this user: userdb uid (113246) doesn't match peer uid (14585) (change userdb socket permissions) Nov 6 11:58:56 myotis30 dovecot: auth: Debug: master out: FAIL#0112 Nov 6 11:58:56 myotis30 dovecot: imap(user2): Error: user user1: Auth USER lookup failed Nov 6 11:58:56 myotis30 dovecot: imap(user2): Debug: auth input: Nov 6 11:58:56 myotis30 dovecot: imap(user2): Error: Couldn't create namespace 'shared/' for user user1: userdb didn't return a home directory, but plugin setting quota used it (%h): dict:User quota::file:%h/Maildir/dovecot.quota It seems that imap process running for user2 is trying to a user lookup that fails. So I have manually tried it root@myotis30:/etc/dovecot/conf.d# sudo -u user2 doveadm user user2 userdb: user2 home : <homeDirectory> uid : 14585 gid : 404 root@myotis30:/etc/dovecot/conf.d# sudo -u user2 doveadm user user1 doveadm(user2): Error: user user1: Auth USER lookup failed doveadm(user2): Error: userdb lookup failed for user1 I have checked the socket permissions, but they are 0666 (if I'm looking the right socket): root@myotis30:/etc/dovecot/conf.d# ls -l /var/run/dovecot/auth-userdb srwxrwxrwx 1 dovecot root 0 nov 6 11:43 /var/run/dovecot/auth-userdb In fact, I have tried to put all sockets with permissions 0666 and 0777, but the error persists.

[Dovecot] LDAP congestion
by Bernhard Schmidt 07 Nov '12

07 Nov '12

Hello, I've been asked to have a look at a misbehaving mail server of some colleagues today where almost all logins where failing or excessively delayed, while the LDAP database itself was pretty fast. They run Dovecot 1.2.11 (yes, I know, stoneage) against an LDAP server run by a 3rd party, auth_bind=yes (required). The problem is that this third party LDAP server delays bindResponse 3 seconds when the password is wrong. A user wanted to login every 2-3 seconds this morning with the wrong password, which effectively killed the system because the LDAP connection was mostly stalled waiting for the auth timeout. >From a previous discussion with Timo I know that bindRequests cannot be parallelized in LDAP, so the problem does not come completely unexpected. Other than removing the failure delay in the LDAP server, is there anything one can do? If there is any change in newer Dovecot versions about that please tell me so I can encourage them to upgrade, but I haven't seen anything in the changelog. Any way to get several LDAP workers/connections for passdb in parallel? Thanks, Bernhard

[Dovecot] "starting" dovecot
by Dave Abrahams 07 Nov '12

07 Nov '12

My system never issues the "dovecot start" command. I do, however, run /usr/local/libexec/dovecot/imap on port 9xxx. I talk to the server through port 9xxx and through the preauth tunnel. Is this arrangement OK? Are there some things that will only work if "dovecot" is invoked?

[Dovecot] Modifying mailbox GUIDs?
by Faheem Patel 07 Nov '12

07 Nov '12

Greetings all, I can view a mailbox's GUID like so: doveadm mailbox status -u guid However, how may I *modify* a mailbox GUID? Can this be done using doveadm or some other tool? If not, how may I go about modifying the dovecot.mailbox.log (where I assume GUID data is stored)? My specific use case has to do with me wanting to modify an existing mailbox's GUID so that its messages are mirrored into a folder of the same name using "dsync mirror". (As we know, dsync utilizes GUIDs to determine mailbox uniqueness) Thanks! -- - Faheem

[Dovecot] Error: Internal quota calculation error
by Micah Anderson 07 Nov '12

07 Nov '12

Hello, I'm using 2.1.7 with seive and mysql quotas. We had an outage the other day where the database server where quotas are stored was not available for a short period of time. In dovecot land, the following types of errors occured in that scenario: Oct 26 22:19:01 grosbeak dovecot: lda(example(a)riseup.net): Error: Internal quota calculation error Oct 26 22:19:01 grosbeak dovecot: lda(example(a)riseup.net): Error: sieve: msgid=<20122132765181x.ABCCE457(a)example.com>: failed to store into mailbox 'Trash': Internal error occurred. Refer to server log for more information. [2012-10-26 22:19:01] Oct 26 22:19:01 grosbeak dovecot: lda(example(a)riseup.net): Error: sieve: script /maildir/e/example/.dovecot.sieve failed with unsuccessful implicit keep (user logfile /maildir/e/example/.dovecot.sieve.log may reveal additional details) I expect that there would be quota calculation errors as dovecot could not reach the database server, but what worried me was the 'failed to store into mailbox' message from sieve. The 'Trash' mailbox in this particular seive script is the correct location for the message to be filed into, but the worrisome message is the 'failed with unsuccessful implicit keep'. I looked through all the message-ids that reported this error and I found that the messages were properly delivered in the end, so this might be some issue interacting between sieve, dovecot and quota and just causing a scary message that can be ignored? thanks for any information you can provide, dovecot is great! micah --
