[Dovecot] Authentication failure - unknown user
by Anne Wilson 11 Jan '06

11 Jan '06

I'm trying to set up a temporary mailserver using Debian Sarge and Dovecot 1.0 with maildir format. My only previous experience has been on a simple imap server with mbox format. I have read the wiki documentation and searched the archives, but can't tie down my problem. The log tells me Info: passwd-file(anne) : unknown user. I have set auth_userdb = passwd-file /etc/imap.passwd auth_passdb = passwd-file /etc/imap.passwd and created the /etc/imap.passwd file as anne:{plain}mypassword:1000:1000::/home/anne What have I missed?

[Dovecot] special variables
by Andrés Pereira 11 Jan '06

11 Jan '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi! Are there any plans to extend the special variables you can use for ldap query strings (%u,%n,etc)? For instance, say you have an ldap schema like this with multiple domains in a single top-level-domain: dc=domain_1,dc=tld_1 dc=domain_2,dc=tld_1 dc=domain_3,dc=tld_1 dc=domain_4,dc=tld_2 dc=domain_5,dc=tld_2 dc=domain_6,dc=tld_2 Now dovecot (latest CVS snapshot) offers, among others, the following variable: %d - domain part in user@domain, empty if there is no domain But, what if dovecot could offer something like this: %1-9 = domain tokens (%1 = tld, %2 = domain when %d = domain.tld) (actually, these variables are present in auth_ldap module for saslauthd) This way people could create a query like this (just an example): base = ou=some_ou,dc=%2,dc=%1 I know I could modify my ldap schema to: dc=domain_1.tld_1 dc=domain_2.tld_1 .... and it would be solved by using %d, however those "new" variables could be useful, what do you think?

[Dovecot] Wild Idea for a feature
by Marc Perkel 10 Jan '06

10 Jan '06

OK - this is a wild idea and wondering what it would take to make it possible. I get a lot of email from a lot of different people about a lot of different issues. What I need is a way to do some server side presorting of email into specific folders. I can build a LOT of Mozilla rules but that is too cumbersome for what I have in mind. Here's what I'm thinking - one classification of email is "customers" and what I want to do is to drag an email into the customers server side folder and once I do that then any incoming email that comes from that person goes into the customers folder. I'm trying to envision how to code this and I think what I would need is if Dovecot were to create an external berkeley db file or mysql database of what is a list of email addresses contained in the folder that could be quickly searched for a match, that might do it. I think I could write a backent in Exim to handle it. This idea isn't yet well though out. I'm just throwing it out there to see if it's feasable. Thoughts?

[Dovecot] Thunderbird, IDLE, mailbox not always SELECTed
by Tom Alsberg 10 Jan '06

10 Jan '06

Hi there. Although it does not seem to be a Dovecot issue, I'm sending this here as people in this list may know better where exactly the problem is. I am working on Dovecot 1.0 (.alpha5, right now), with the aim that when Dovecot becomes stable we can put that into production. Recently after being more clear with the behaviour (I'm most into namespaces and mbox/maildir mixing issues, as you can see from my past messages), I have adopted a few (two, right now, with the third one gone) "Guinea-Pigs" to use the experimental IMAP server - people who very much want an IMAP service here and thus may help me test bugs. One of them reported, that he does not always see new mail. That user is using Mozilla Thunderbird (1.0.7). Looking a bit with him at the workings, I can see the issue. He has the IDLE extension enabled. However when sniffing the network, I see that sometimes when switching to another mailbox, the SELECT command is not always sent to the server. At the beginning, INBOX is (always) selected. Then another mailbox is selected, and usually a SELECT command is sent and the mailbox is seen. But going back to INBOX again, often no "SELECT INBOX" is seen on the wire. Then of course he sees no "EXISTS" or anything like that. I wonder if anyone else has observed this, or in some other way, that Thunderbird does not always show new mail. Sometimes it appears that a mailbox is selected in Thunderbird, and Thunderbird immediately (remembering from its cache) does a FETCH to show the message in the mailbox/folder, but not SELECT to update the folder itself. Can caching in Thunderbird be completely disabled, so that every action will be done against the server?

[Dovecot] dovecot auth using passwd-file
by Brad 10 Jan '06

10 Jan '06

Im a dovecot newbie and need a little help with the passwd-like file auth mechanism in dovecot I got dovecot to work fine with regular /etc/passwd file auth .. so I wanted to start using another authentication store for virtual users. So .. I created a /etc/dovecot-passdb file and plopped in an encrypted password using md5crypt. Here are the appropriate lines from the dovecot.conf file auth_userdb = passwd-file /etc/dovecot-passdb auth_passdb = pam and here is the /etc/pam.d/dovecot file #%PAM-1.0 auth required pam_nologin.so auth required pam_stack.so service=system-auth account required pam_stack.so service=system-auth session required pam_stack.so service=system-auth So far .. no dice. Dovecot reports constant authentication failures. I fear that the dovecot-passdb file is wonky. Can anyone give me any pointers ?

[Dovecot] Maildir permissions, shared folders & postfix
by Stroller 09 Jan '06

09 Jan '06

Hi there, It's my understanding that shared folders can be implemented in the Dovecot IMAP server by simply symlinking one maildir to another, eg: $ ls -lan /home/DOMAIN/ned/.maildir/ total 40 drwx------ 9 10012 10000 440 Jan 9 04:23 . drwxr-xr-x 3 10012 10000 160 Jan 6 06:32 .. drwx------ 5 10012 10000 264 Jan 9 04:21 .Deleted Items drwx------ 5 10012 10000 232 Jan 6 06:32 .Drafts drwx------ 5 10012 10000 232 Jan 6 06:39 .Junk E-mail drwx------ 5 10012 10000 264 Jan 9 04:33 .Sent lrwxrwxrwx 1 10012 0 24 Jan 6 07:36 .Stroller -> /home/ stroller/.maildir/ drwx------ 2 10012 10000 336 Jan 9 04:23 cur -rw------- 1 10012 10000 268 Jan 9 04:23 dovecot-uidlist -rw------- 1 10012 10000 192 Jan 9 04:23 dovecot.index -rw------- 1 10012 10000 21504 Jan 9 04:23 dovecot.index.cache -rw------- 1 10012 10000 1908 Jan 9 04:23 dovecot.index.log drwx------ 2 10012 10000 48 Jan 9 04:23 new -rw------- 1 10012 10000 47 Jan 6 07:45 subscriptions drwx------ 2 10012 10000 48 Jan 9 04:23 tmp In the above configuration the user Ned has a mailbox "Stroller", in which he can read messages & stuff - I can log in as ned and drag & drop messages into this mailbox quite happily. I thought all was well with this type of shared configuration until I actually started to try setting it up for the info(a)ourdomain.com mailbox, and tried delivering messages to it. It seems that Postfix doesn't respect the permissions of the parent folder when delivering mail into it: # ls -ldn /home/info/.maildir/ drwxrwx--- 5 10021 10000 120 Jan 9 04:26 /home/info/.maildir/ # ls -ln /home/info/.maildir/ total 0 drwxrwx--- 2 10021 10000 48 Jan 9 04:26 cur drwxrwx--- 2 10021 10000 48 Jan 9 04:33 new drwxrwx--- 2 10021 10000 48 Jan 9 04:31 tmp # ls -ln /home/info/.maildir/new total 0 # cat HungUp.txt | sendmail info # sudo ls -l /home/info/.maildir/new total 4 # sudo ls -ln /home/info/.maildir/new total 4 -rw------- 1 10021 10000 1806 Jan 9 04:39 1136781544.V4804I3606cM633316.mail.domain.local How inconsiderate of Postfix to set secure permissions on the message it delivered!! I need the message to have 660 permissions so that others in the group can read it! At present this causes Squirrelmail to squeal & give nasty messages whenever a shared mailbox is accesses. Can anyone advise me how to resolve this, please? Stroller. PS: should you consider suggesting using Dovecot's "namespaces" type of shared mailbox, I'd be grateful if you could answer this first: http://dovecot.org/pipermail/dovecot/2005-December/010459.html

[Dovecot] POP3 only - why is cur/ growing?

Hi, I use Sarge's dovecot for a pop3 mail collection server. IMAP is not used at all. It works well, but I would like to know why one of the accounts also keeps a copy of all e-mail copies in the cur/ folder?
