[Dovecot] displaying IMAP folders that are in ~/mail/ at same level as inbox
by David London 22 Oct '08

22 Oct '08

Hi, We are moving our current IMAP based system to a new one with dovecot All I can get about the current IMAP (imapd) system is: IMAP4rev1 v12.264 dovecot version is: 1.0.rc15 In the existing system I can see IMAP folders that are in ~/mail/ with many mail clients (e.g. Thunderbird, Outlook, Seamonkey and horde). These folders are presented in the client software as being at the same level as the inbox - i.e. not inside the folder "mail" On the new system, horde webmail shows the other folders in ~/mail/ as being at the same level as the inbox. But ... all the other mail clients above now show a folder (directory) called mail with the imap folders inside. Is there some way to set this up so these other mail clients see the imap folders in ~/mail/ as being at the same level as the inbox as we have on the old server? Thanks, David _________________________________________________________________

[Dovecot] Permission issues with subscriptions
by Eric A. Bonney 22 Oct '08

22 Oct '08

I am having some permission issues with my setup and I can't see where to make the change in the configuration files. My users can not create folders at all from their email clients nor from the web interface. I have noticed that each time I try to create a folder the subscriptions files permissions are set to 000. If I go back and reset the permissions to rw-r--r-- then everything is fine until I try to add another folder. running dovecot -n produces the following: # 1.0.10: /etc/dovecot/dovecot.conf listen: [::] login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login verbose_proctitle: yes first_valid_uid: 1000 default_mail_env: maildir:/mnt/hd4/MailBoxes/%d/%n mail_location: maildir:/mnt/hd4/MailBoxes/%d/%n umask: 511 auth default: user: nobody passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: prefetch I am guessing that Dovecot is the actual process that is creating the folders on the IMAP server, so where inside the configuration file do I set the permissions for the new folders along with the user and groups? Thanks, -Eric

[Dovecot] Proxying pop3 sessions into an imap one.
by Diego Liziero 22 Oct '08

22 Oct '08

I know it seems at least unusual. But I would like to know if someone knows a software that can proxy multiple pop3 and imap connections to the same account and use only imap connections to the real server. I need it because I've to deal with two pieces of software that are out of my control: - 1 - A certified mail provider that states something that I would like to know if it's really true, or if it's worth keeping like a funny signature: "multiple imap sessions are possible. When an imap session is active, no pop3 connections are possible on the same account; when no imap connection is active, only one pop3 connection at a time is possible on the same account. This is a limitation of the pop3 protocol." - 2 - A software written to deal with certified mails that supports only pop3 used by many people on the same account, (and the same account is used also by multiple imap mail readers). Regards, Diego.

[Dovecot] 1.2: Bug in listing of shared mailboxes with dot in user id
by Sascha Wilde 21 Oct '08

21 Oct '08

In dovecot 1.2 I can create a shared name space like this: namespace shared { separator = / prefix = users/%%u/ location = Maildir:/PATH/TO/spool/%%u/maildir:INDEX=/PATH/TO/spool/%u/maildir/shared_idx subscriptions = no } now, when I subscribe to a shared mailbox of another user with an dot in the users id, like: users/2(a)example.com/INBOX/foo and I list my subscribed mailboxes I get: l001 lsub "" "*" * LSUB () "/" "users/2@example/com/INBOX/foo" as you can see the dot in the user-id got normalized to the hierarchy seperator `/' -- which of cause is wrong. ;-) cheers sascha -- Sascha Wilde OpenPGP key: 4BB86568 http://www.intevation.de/~wilde/ http://www.intevation.de/ Intevation GmbH, Neuer Graben 17, 49074 Osnabrück; AG Osnabrück, HR B 18998 Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner

[Dovecot] Reporting NFS quotas via IMAP
by Edgar Fuß 21 Oct '08

21 Oct '08

I'm confident that the question has been asked before, but I can't remember the answer. I have -- dovecot 1.1.2 -- Mail storage (maildir format) on NFS -- Quotas on that file system -- A working rquotad -- mail_plugins = quota imap_quota in the protocol imap section -- quota=fs in the plugin section I get (using Apple Mail as a client) -- Notification that the account supports quotas -- No information about the size of the quota nor the usage I probably do something stupidly wrong. The WIKI tells me that fs quota support RPC (i.e., rquotad), so I'd expect my client to report the quota to me. Using quota(1) on the mail server works as expected.
