[Dovecot] Trash for lda
by Alaa Ibrahim 30 Jan '09

30 Jan '09

Hi, I was wondering if there is a solution to the case when the user can't recieve emails because of being over quota, something like http://wiki.dovecot.org/Plugins/Trash, but for the lda, not the imap?

30 Jan '09

hi- i'm using ldap for user authentication, and would like to use different ldap lookups for authentication happening via postfix (smtp auth) vs. authentication happening through dovecot (imap logins). how can this be done, without running multiple instances? thanks! -bt

Re: [Dovecot] Problem with dovecot config

Hi, I'd like to do option A, but I'm not certain as to what steps to take to do so. Could you let me know where the code for this function is located, and what might need to be done to link it? I'm not terribly familiar with the linker, so I'm having a bit of trouble figuring out what exactly needs to be done for the rebuild.

[Dovecot] deliver and qmail
by Tim Traver 29 Jan '09

29 Jan '09

Hi all, ok, after looking at all of the posts that I've found, and trying numerous settings, I am a little stumped as to how to set up the deliver program with qmail to get everything correct. Ultimately, I really don't want to do a lookup of the home dir if I don't have to. I'd rather specify the stuff in the .qmail-user file for that particular user to avoid the extra step. In looking in the wiki, it says for users without a lookup to use HOME=/path/to/user/homedir deliver -f $FROM_ENVELOPE but I can't do that in the .qmail file, which would normally look something like this : |/var/qmail/bin/preline -f /usr/local/libexec/dovecot/deliver -f ${SENDER:-<>} I would rather not do the master authentication socket as described for obvious reasons. is there a format in the .qmail file that I can use with deliver to achieve what I want??? Thanks, Tim.

[Dovecot] Confused about permissions needed for shared mailbox
by Thomas Hummel 28 Jan '09

28 Jan '09

Hello, let me re-state, hopefully in clearer terms, what I tried to described in a previous thread : With dovecot-1.1.8/Maildir/LDAP pass/userdb (prefetch), I'm trying to set up a Maildir ".box" shared in rw between 2 users in a "Public" namespace. I can't get it to work unless I chmod 777 everything, which obiously is not what I want. 1) am I correct thinking that the system_user userdb extra_field and unix permissions should be enough to achieve that and that ACLs is only if I want to fine tunes mailbox permissions ? 2) let's say that my public namespace prefix is Public/, that the .box/ maildir is in /path/to/public/.box and my 2 users belong to the doveshared unix group. I thought it would be enough to have drwxrws--- 3 root doveshared 4096 Jan 28 14:55 public drwxrws--- 3 root doveshared 4096 Jan 28 14:55 public/.box -rwxrws--- 1 root doveshared 0 Jan 26 18:25 public/.box/dovecot-shared provided that my prefetch userdb returns system_user, as I think the following says in dovecot-ldap.conf : pass_attrs = uid=user,userPassword=password,homeDirectory=userdb_home,,,uidNumber=userdb_uid,gidNumber=userdb_gid,shadowMax=userdb_system_user and providedt that in LDAP shadowMax: 80 (whatever value). But this doesn't seem to work. By the way : Am I supposed to have a dovecot-shared file in public as well (that is not only in public/.box) ? 3) let's say I try ACLs with the same setup (anyone <all permissions> for starters) would pass_attrs = uid=user,userPassword=password,homeDirectory=userdb_home,,,uidNumber=userdb_uid,gidNumber=userdb_gid,shadowMax=userdb_system_user.title=userdb_acl_groups and title: group1,doveshared be a correct setup ? Do I need an dovecot-acl file only in .box or in public too ? My understanding is that my setup doesn't work because for some reason, dovecot doesn't see my users secondary groups or doesnt take them into account... Any thoughts which might help ? -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] Symlink shared mailboxes and system_user extra field
by Thomas Hummel 28 Jan '09

28 Jan '09

Hello, I'm trying to set up, as explained in the wiki, shared mailboxes with symlink. I'm running dovecot-1.1.8 with LDAP pass/userdb. The Maildir layout goes like this : /courriel/boites/foobar : Maildir of user foobar (nfs) /courriel/meta/foobar : control files of user foobar (nfs) /var/dovecot/indexes : indexes (locally stored) I created : /courriel/boites/doveshared/.box/ : the Maildir I want to share /courriel/boites/foobar/.box -> /courriel/boites/doveshared/.box (symlink) /courriel/boites/foobaz/.box -> /courriel/boites/doveshared/.box (symlink) the unix and LDAP group doveshared, so /etc/group holds : doveshared:*:<gid>:foobar,foobaz the permissions on the real Maildir are ok for that group : drwxrwx--- 3 root doveshared 4096 Jan 26 18:58 /courriel/boites/doveshared drwxrwx--- 5 root doveshared 4096 Jan 26 18:58 .box (in /courriel/boites) I made the userdb (prefetch) return the system_user extra_field (for now, I'm using an used LDAP attribute - I will create a new attribute in my schema later) : pass_attrs = uid=user,userPassword=password,homeDirectory=userdb_home,,,uidNumber=userdb_uid,gidNumber=userdb_gid,shadowMax=userdb_system_user and it seems to be actually returned : Jan 27 09:34:10 munster3 dovecot: auth(default): ldap(foobar,157.99.64.42): result: uid(user)=foobar uidNumber(userdb_uid)=xxx gidNumber(userdb_gid)=xxx homeDirectory(userdb_home)=/home1/xxx/foobar userPassword(password)=<hidden> shadowMax(userdb_system_user)=380 But I can't subscribe to the mailbox : stat(/courriel/boites/doveshared/.box/tmp) failed: Permission denied (euid=xxx egid=<primary gid>) as a matter of fact, the egid seems to be the primary gid. What am I missing ? Thanks. -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] (imap) killed with signal 9 on Linux/OpenVZ VPS
by Adam Flott 28 Jan '09

28 Jan '09

I'm trying to get dovecot running on my VPS and the main imap process is receiving a SIGKILL from what I presume to be the Linux Kernel and/or OpenVZ. This happens after I login and my client(s) just sit their idling. The mailbox is empty. I'm not running out of memory. stracing the process doesn't show anything interesting... ... gettimeofday({1233024777, 844804}, {420, 0}) = 0 gettimeofday({1233024777, 844912}, NULL) = 0 poll([{fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=2, events=POLLERR|POLLHUP|POLLNVAL}, {fd=0, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 3, 10000) = -1 EINTR (Interrupted system call) +++ killed by SIGKILL +++ This is on a CentOS 5.2 VPS. I haven't changed much other than installing a few packages. I've also had this exact same problem on Debian 4.0 VPS (OpenVZ) under the same machine. Turning off SSL and logging in plain old IMAP didn't change anything. Under the Debian installation I tried the latest version of dovecot (1.1.8 or so), different I/O loop methods, turning them off, on, etc. The only other reference via Google I can find to this sort of problem is: http://www.dovecot.org/list/dovecot/2007-December/027440.html But that was with the login process, whereas mine is with the imap daemon. Any help is greatly appreciated.
