[Dovecot] Messages not moved from Inbox by Apple Mail (Dovecot 1.0.10)
by Tom Collins 28 Jan '08

28 Jan '08

I just upgraded a server from Courier-IMAP to Dovecot, and I'm seeing some odd behavior. It's probably the result of something I did wrong in my configuration, and I'm hoping someone will let me know the easy fix for it. I have rules set up in Apple Mail to move and copy messages to different folders, some of which are IMAP folders, others on my own system. With Courier-IMAP, the messages would get moved without a problem. With dovecot, that's not happening. Here's my dovecot config. I've tried changing maildir_copy_with_hardlinks and maildir_copy_preserve_filename to "no", but that didn't seem to help. # 1.0.10: /usr/local/etc/dovecot.conf disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login verbose_proctitle: yes first_valid_uid: 89 last_valid_uid: 89 first_valid_gid: 89 last_valid_gid: 89 maildir_copy_with_hardlinks: yes maildir_copy_preserve_filename: yes namespace: type: private prefix: INBOX. inbox: yes auth default: mechanisms: plain login digest-md5 cram-md5 username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@% username_translation: %@ passdb: driver: vpopmail userdb: driver: vpopmail plugin: quota: maildir I haven't tried logging the IMAP session yet, but I can turn off SSL, fire up Wireshark and monitor the session if necessary. Is this a known problem? I'm able to move messages between folders manually, but when Apple Mail moves the new messages it doesn't work. -- Tom Collins - tom(a)tomlogic.com Vpopmail - virtual domains for qmail: http://vpopmail.sf.net/ QmailAdmin - web interface for Vpopmail: http://qmailadmin.sf.net/

[Dovecot] Dovecot/SeLinux issues after RHEL5.1 upgrade
by Ion Soltan 28 Jan '08

28 Jan '08

Hello to everyone on the list, I have upgraded my RHEL4 to RHEL5.1 yesterday (all updates have been applied to it as well). I used to have dovecot v0.99.11 on the old system. Everything was working fine. Now I have 5.1 and its respective dovecot v1.0.rc15. Upon upgrading to RHEL5.1, dovecot no longer works correctly. The first thing I did after rewriting the config file for the updated version, was to check my own email. It works fine. However, no other user on the system can check his/hers. Here is what the log shows for everyone except myself: ============================ Jan 27 13:56:41 warp dovecot: POP3(jj): open() failed with file /home/jj/mail/.imap/INBOX/dovecot.index.log: Permission denied Jan 27 13:56:41 warp dovecot: POP3(jj): open() failed with file /home/jj/mail/.imap/INBOX/dovecot.index.log: Permission denied Jan 27 13:56:41 warp dovecot: POP3(jj): Couldn't open INBOX: Internal error occurred. Refer to server log for more information. [2008-01-27 13:56:41] ============================ There are NO complaints reported by selinux in the logs. If I setenforce 0 (disable selinux), everything is working fine for everyone. If I disable selinux monitoring on dovecot (setsebool dovecot_disable_trans 1), nothing changes, which makes me think that something else is causing the problem. I do very much want to use selinux, however, I cannot figure out what the problem is and I have been trying for many hours. Can anyone help? Thanks, Ion

[Dovecot] Shared mailboxes
by Wouter Amsterdam 28 Jan '08

28 Jan '08

L.S. It is not clear to me why I should use namespaces or symlinks to share a single maildir mailbox with multiple users. Why not configure multiple mail clients with the same account information? TIA, Wouter

[Dovecot] Howto set mail_location for system users over LDAP?
by Patrick Ben Koetter 28 Jan '08

28 Jan '08

In parallel to /etc/passwd I do have my system users in LDAP. I want to store their messages in /srv/mail/state-of-mind/<username>. Dovecot has been configured to retrieve the extra field mail to override the mail_location setting. I can see in the log it retrieves the correct information as long as I run Dovecot deliver as Postfix service 'dovecot' as shown in section "Virtual users" <http://wiki.dovecot.org/LDA/Postfix>. However if I use deliver as specified for "System users" it ignores the LDAP settings and delivers messages to my users $HOME directory as specified in /etc/passwd. Is this correct behaviour? What do I need to do to use the Postfix $mailbox_command _and_ have Dovecot deliver honor my LDAP settings?

[Dovecot] Thunderbird Problem - What causes this?
by Marc Perkel 27 Jan '08

27 Jan '08

Strange problem and I'm not sure what's causing it. I'm using IMAP. A new message arives in the inbox. I see it displayed in the message list in bold. I click on the message and it looks like it's reading it by the previous message that was in the window remains and the new message is still bold (unread). However I can then click on an old message and then click on the new message again and it reads. I have also seen Thunderbird be in a somewhat unresponsive state. You can click on messages and they don't read. But Shutting down Thunderbird and restarting it make it responsive again. Has anyone seen this?

[Dovecot] proxy configuration
by bill-dovecot＠carpenter.ORG 27 Jan '08

27 Jan '08

Before I spend some time experimenting with what might be impossible, maybe someone can just tell me (either "how" or that it's impossible). I'd like to get perdition out of my environment (mainly to have one less moving part in my architecture). I'm looking at dovecot's built-in proxying. In my setup, I don't have dedicated front-end machines. A user can connect to any server, but their mail files live on one particular machine. I'd like to transparently proxy them from whatever machine they happen to hit to their home machine. Except for the "proxy_maybe" feature advertised for dovecot 1.1, I don't see a surefire way to do this. Has anyone done it, or can anyone say for sure that it can't reasonably be done until "proxy_maybe"?

[Dovecot] Thunderbird trouble with Dovecote and dbox
by Hannes Dorbath 27 Jan '08

27 Jan '08

Hi, I'm new to Dovecot -- migrating from Cyrus. Version and config: # 1.1.beta14: /etc/dovecot/dovecot.conf protocols: imaps login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_location: dbox:/data/mail/%u auth default: passdb: driver: pam args: * userdb: driver: passwd Linux 2.6.22-gentoo-r10 x86_64 GNU/Linux I have chosen dbox as mailbox format as it is claimed to be the best performing -- and performance is the reason I'd like to migrate away form Cyrus. I'm aware that dbox might not be 100% mature, but I'm good at doing backups. Anyway, so far I have the following problems: - Greyed out Inbox After creating a new user and connecting to that account with Thunderbird the first time, the INBOX folder is greyed out and in italic. Restarting Thunderbird 3-4 times seems to fix the problem. Google suggests that other people have seen the same, but they never found a solution. - After creating sub folders they are not displayed, I need to manually subscribe to them after creation. - When "Trash" contains folders, Thunderbird is unable to "Empty Trash". While the folder is removed from Thunderbird's folder tree, it's there again after a restart of Thunderbird. - Deleted folders are never deleted from the file system. I'm not sure if this is intended with dbox. - Moving folders via drag & drop does not work, it just does nothing. So basically nothing besides reading existing mails seems to work reliable. My basic questions now is, are those problems related to dbox, or to Dovecot and Thunderbird in general? -- Best regards, Hannes Dorbath
