/usr/lib/dovecot/imap exits with an error if stderr closed
by Josh Triplett 01 Oct '15

01 Oct '15

At the end of a direct IMAP conversation with the imap binary, it writes an informative message like "imap(josh): Info: Connection closed in=0 out=365" to stderr. With stderr closed, the imap binary will exit with exit code 81 after it gets EBADF from that write. While it makes sense to fail on failure to write an error message, I don't think it makes sense to fail if writing an info message fails. I encountered this when using /usr/lib/dovecot/imap with mutt's "tunnel" option. Mutt seems to run the configured tunnel program with stderr closed, which triggers this error. - Josh Triplett

Dovecot 1.0.10 - Authenticate against LDAP with multiple sub-trees
by Daniel Heitepriem 01 Oct '15

01 Oct '15

Hi guys, I'm using Dovecot 1.0.10 with LDAP authentication. Below is my dovecot-ldap.conf { hosts = *IP of LDAP server* auth_bind = yes auth_bind_userdn = uid=%u,ou=people,dc=*something*,dc=com ldap_version = 3 base = %u,ou=people,dc=*something*,dc=com deref = never scope = subtree user_filter = (&(objectClass=person)(uid=%u)) } And the current structure: Base | |-- people | | *user entries* | Now I want to update to a LDAP server with the following structure: Base | |-- people | |-- staff | | *user entries* |-- other location | | *user entries* | How can I keep my "auth_bind_userdn" using this new structure? Hopefully somebody can help me :) Regards, Daniel

SiS and attachments filename
by Angel L. Mateo 01 Oct '15

01 Oct '15

Hi, I've been working with dovecot SiS for a long time without any problem. This is my configuration for SiS: mail_attachment_dir = /mail/users/attachments mail_attachment_fs = sis posix mail_attachment_hash = %{sha1} mail_attachment_min_size = 128 k With this configuration, I have, for example: # ls -l /mail/users/attachments/27/d1/27d1904ac9947945bf48ea545ec278940d840ed1* -rw------- 12 vmail vmail 142914 may 6 2013 /mail/users/attachments/27/d1/27d1904ac9947945bf48ea545ec278940d840ed1-090d88269ad28851f14b0000a9061514 ... And every file is a hard link to /mail/users/attachments/27/d1/hashes/27d1904ac9947945bf48ea545ec278940d840ed1 For the documentation I have found, "27d1904ac9947945bf48ea545ec278940d840ed1" is a hash of the attach content, but what does the other part of the filename (the "090d88269ad28851f14b0000a9061514" means) My question has come to my mind because I need an easy way to find the mailbox where this attach is referenced from. -- Angel L.

Maybe you need to set the INBOX parameter directly. http://wiki2.dovecot.org/MailLocation Joseph Tam <jtam.home(a)gmail.com>

userdb prefetch doesn't work with imapc (2.2.18)
by Nagy, Attila 30 Sep '15

30 Sep '15

Hi, I have the following config in dovecot 2.2.18: # doveconf -n userdb passdb userdb { driver = prefetch } passdb { args = host=127.0.0.1 port=1430 default_fields = userdb_imapc_user=%u userdb_imapc_password=%w driver = imap } I guess it should cause a single login to the backend IMAP server when issuing a LOGIN to dovecot. Yet, dovecot opens two TCP sessions. In the first, it issues a LOGIN and in the second it logs in again (LOGIN) and issues LIST "" "". At the end (after LOGIN succeeds to dovecot), only one of the two connections remain open to the backend server. Any ideas about this? Thanks,

v2.2.19 release candidate 2 released
by Timo Sirainen 30 Sep '15

30 Sep '15

http://dovecot.org/releases/2.2/rc/dovecot-2.2.19.rc2.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.19.rc2.tar.gz.sig There were still a bit too many bugs in RC1, so here's RC2. Hopefully this will be stable enough to become v2.2.19 final. Please test now rather than wait for v2.2.19 final, since v2.2.20 is unlikely to arrive anytime soon (unless there are some major problems). Some fixes since RC1: - dict fixes, especially with pgsql - virtual plugin crashfixes - quota "count" backend fixes - lib-http fixes - some compiling fixes
