[Dovecot] Can't rename mailboxes, any ideas on how to fix?
by Howard Leadmon 04 Jan '13

04 Jan '13

I am running Dovecot 2.1.12 under FreeBSD, and I use Outlook 2010 with imap to connect to my server. I know I used to be able to rename mailboxes, as I do this every year at year end, but when I went to rename some mailboxes the start of this year, blamo up popped the message "CANNOT Renaming not supported across conflicting directory permissions". Then only thing that has really been updated here, is Dovecot itself, as I know the FBSD port updates when new versions are released. Any clues on what may have caused this, or how to best correct it? --- Howard Leadmon

[Dovecot] Dovecot 1.2.7 and Roundcube LIST-EXTENDED commands
by aristidis fesarlis 04 Jan '13

04 Jan '13

Hi all, we use Dovecot 1.2.7 with Maildir, and recently we have set up the latest Roundcube webmail. Inside its config file,it is mentioned that: // By default list of subscribed folders is determined using LIST-EXTENDED // extension if available. Some servers (dovecot 1.x) returns wrong results // for shared namespaces in this case. http://trac.roundcube.net/ticket/1486225 // Enable this option to force LSUB command usage instead. I notice that it seems to work fine, though. We don't have shared namespaces. So my question is: should I change it to LSUB, or will I have problems with my Maildir subscriptions? Thanks

[Dovecot] Dovecot auto subscribe imap public folder
by Marantz 04 Jan '13

04 Jan '13

Hi, I have a public folder up and running. This public folder is shared across the company, but when one user makes a new folder then it is not automatically visible to othe users. They need to subscribe manually. Is there a way to automatically subscribe to this? Kind regards, Robin -- View this message in context: http://dovecot.2317879.n4.nabble.com/Dovecot-auto-subscribe-imap-public-fol… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Folder names
by James Starowitz 04 Jan '13

04 Jan '13

Running a pretty basic setup of imap +pop3 on version 2.1.10 Users are able to create folders in imap that contain "&" the folder on the backend reflects "&-" as it should, you can list folder, but then when you relog into imap then decides it can no longer subscribe to this folder due to invalid UTF characters. Essentially allowing users to lock themselves out by using a very common character in a folder name. Might one of the imap client compatibility plugins in imapd cause this quirkiness ? Should I be coming at this from another direction? Is this a bug?

[Dovecot] Kerberos/GSSAPI auth via .k5login file
by Jörg Herzinger 04 Jan '13

04 Jan '13

Hi, we are currently moving our mailserver to a new server with Dovecot, virtual users in LDAP, Passwords in Kerberos Setup. Everything works fine except for GSSAPI which seems to be a bit buggy. The thing is, that when using a .k5login [1] file it seems that SASL does not get passed the home directory specified userdb. In other words, mails for user1 (see below) are stored in /home/domain.at/user1, while the home dir defined in LDAP is /afs/domain.at/home/user1 (virtual users, so only dovecot, not the system does know about this user and home dir). If I do create a .k5login file in /home/domain.at/user1 with the content "someotheruser(a)DOMAIN.AT", then someotheruser should be able to authenticate himself as user1 via GSSAPI. However, this .k5login file is completely ignored. So it seems to me that the home is not passed on to SASL. If I do add ldap to my nsswitch (for testing only) I additionally have real system users. Now if I create a .k5login in their home defined in LDAP which now also the system knows about everything works just fine. It is still the wrong home since its the one in LDAP and not the one defined by dovecot but at least it shows that our setup is working. See also debug log output below, a failed GSSAPI attempt produces no log output at all. Our System is Debian Wheezy on an amd64 (virtualized), dovecot Version 2.1.7, filesystem is ext4. Everything is tested with Firefox 17.0 on an Ubuntu Lucid client.

[Dovecot] map_uid/GUID at IMAP level (IMAP extension?)
by Andrzej A. Filip 04 Jan '13

04 Jan '13

Is map_uid/guid going to be supported at IMAP protocol level? [via IMAP protocol extension] Specifically I would like to be able to: a) ask for mail_uid/GUID of specific message in mail store b) get list of folders containing copies of message with given mail_uid/GUID http://wiki2.dovecot.org/MailboxFormat/dbox#Multi-dbox Related: https://developers.google.com/google-apps/gmail/imap_extensions#access_to_t… [message to guid mapping] https://developers.google.com/google-apps/gmail/imap_extensions#access_to_g… [message to list of folders mapping]

[Dovecot] dovecot and avahi
by Robert Moskowitz 03 Jan '13

03 Jan '13

I am trying to figure out if I need avahi on my mail server. I see that POP3 and IMAP are services that Avahi can advertise/discover. Does Dovecot work with Avahi and how do you get POP3 and IMAP advertised? And perhaps more importantly, what clients look for mail services this way? I can't find any information on this in the Dovecot documentation ot googling. Perhaps my search fu is low this year. thank you

[Dovecot] Migration Problem UW-IMAP to Dovecot Maildir
by Michael Sloan 03 Jan '13

03 Jan '13

I've just replaced our ancient (10-year old) mail server running Sendmail/UW-IMAP on Solaris with Postfix/Dovecot 2.1.10 running on Linux on new hardware. I opted to go with virtual users and I didn't want to create system accounts and I might end up hosting another department's mail as well. We have a mix of POP3 and IMAP users, roughly 90 total. The POP3 user mailboxes migrated without a hitch, and the IMAP user mailboxes (in what looks like mbox format) migrated well for the INBOX (found in /var/mail/<username> ) but for those few who managed to create local folders and had mail files in their home directories, those mail files were ignored. Is there any clean way to manage to migrate those folders to the new server now? There were no .mailboxlist or .subscription files anywhere on the old mail server. When I was planning the migration, I tried a variety of the methods listed on the UW-IMAP and generic migration pages including dsync, uw2dovecot.pl, and several others. What appeared to work well at the time was this, although I still have the mail in users' home directories to recover/migrate: /usr/local/bin/doveadm -o imapc_user=$1 -o pop3c_user=$1 -o imapc_password=$2 -o pop3c_password=$2 backup -R -u $1(a)caps.fsu.edu imapc: with this dovecot.conf: # 2.1.10: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 3.0.13-0.27-pae i686 SUSE Linux Enterprise Server 11 (i586) ext3 auth_mechanisms = plain login disable_plaintext_auth = no imapc_features = rfc822.size imapc_host = p1.caps.fsu.edu imapc_list_prefix = INBOX listen = * mail_location = maildir:/var/vmail/%d/%n/Maildir namespace { hidden = yes list = no location = pop3c: prefix = POP3-MIGRATION-NS/ } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = separator = . } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { pop3_migration_mailbox = POP3-MIGRATION-NS/INBOX } pop3_uidl_format = %08Xv%08Xu pop3c_host = p1.caps.fsu.edu service auth { unix_listener /var/run/dovecot/auth-master { mode = 0600 user = vmail } unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = uid=vmail gid=vmail home=/var/vmail/%d/%n allow_all_users=yes driver = static } protocol lda { auth_socket_path = /var/run/dovecot/auth-master log_path = mail_plugins = postmaster_address = postmaster(a)caps.fsu.edu } protocol doveadm { mail_plugins = " pop3_migration" } -- Michael Sloan Systems Administrator FSU Center for Advanced Power Systems sloan(a)caps.fsu.edu
