Dovecot is looking for .dovecot.lda-dupes in the wrong place
by Michael 03 Sep '14

Hi, I just moved the dovecot maildir location for all virtual users to another location. I moved everything from /var/mail/vhosts/%d/%n to /var/vmail/%d/%n/maildir Everything seem to be fine except of one recurring error: Sep 2 10:16:09 mx0 dovecot: lmtp(13226, sv_bogies(a)neurohr.at) Error: file_dotlock_open(/var/mail/vhosts/domain.at/michael/.dovecot.lda-dupes) failed: No such file or directory Sep 2 13:31:27 mx0 dovecot: lmtp(16248, sv_bogies(a)neurohr.at) Error: file_dotlock_open(/var/mail/vhosts/domain.at/michael/.dovecot.lda-dupes) failed: No such file or directory So Dovecot is looking in the old path.

Trouble viewing Inbox via IMAP Client
by Peter Cook 02 Sep '14

02 Sep '14

Hello, I have been having trouble with this issue for quite some time now. Here is my environment: CentOS 6.5, Postfix built with PGSQL support, PFA, and dovecot. The problem I am having is that I can send and receive mail fine, but when I try to view my Inbox in an IMAP client like Thunderbird, I can only view sent mail and trash. Here is the result of my dovecot -- version and dovecot -n --version 2.0.9 dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-431.el6.x86_64 x86_64 CentOS release 6.5 (Final) ext4 auth_debug = yes auth_debug_passwords = yes disable_plaintext_auth = no mail_location = maildir:/var/mail/vmail/%d/%n/ mbox_write_locks = fcntl passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } passdb { driver = pam } protocols = imap pop3 service auth { group = postfix unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = postfix } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } userdb { driver = passwd }

dsync-server couldn't create .dovecot-sync.lock file
by Listas＠Adminlinux 02 Sep '14

02 Sep '14

My dovecot stores users' emails on /var/spool/imap/<user> and stores the messages index on /var/lib/imap/<user>. I have many users who do not yet have their userdb_home directories created on the server, because that is created at the time of first login. I'm testing dsync for replication and have seen the following error: dsync-server(<user>): Error: Couldn't create lock /var/lib/imap/<user>/.dovecot-sync.lock: No such file or directory The /var/lib/imap/<user> directory does not exist yet and I think this is the cause.

Master user and non-plaintext auth does not work

mail_location hashing & lowercasing?
by Ralf Hildebrandt 31 Aug '14

31 Aug '14

Currently, I'm using mail_location = mdbox:/var/spool/mail/%Ld/%Ln/mdbox Now I want to add a partitioning (so I don'T have all directories in one single directory), but can't find the right syntax: mail_location = mdbox:/var/spool/mail/%Ld/<HASHING HERE>/%Ln/mdbox It seems like I'd need to use %N (new hash) on %Ln and then take a substring of that. %2NLn 2 Characters of the %N hash of %Ln (the lowercase username) But this gives me a verbatim "Ln" on the path! -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein

Need help to compile and install a minimal dovecot imap plugin
by Stefan Arentz 31 Aug '14

31 Aug '14

I am trying to create a plugin that adds a new IMAP capability. So far I have this: const char *foo_plugin_version = DOVECOT_ABI_VERSION; static struct module *foo_module; static imap_client_created_func_t *next_hook_client_created; static void foo_client_created(struct client **client) { str_append((*client)->capability_string, " XFOO"); if (next_hook_client_created != NULL) { next_hook_client_created(client); } } void foo_plugin_init(struct module *module) { i_info(“init”); foo_module = module; next_hook_client_created = imap_client_created_hook_set(foo_client_created); } void foo_plugin_deinit(void) { i_info(“deinit”); imap_client_created_hook_set(next_hook_client_created); } const char foo_plugin_binary_dependency[] = "imap”; On Fedora 20, with the dovecot and dovecot-devel packages installed, I compile this with: cc -Wall -shared -fPIC -DHAVE_CONFIG_H -I/usr/include/dovecot -o lib20_foo_plugin.so foo-plugin.c And then install with: sudo cp lib20_foo_plugin.so /usr/lib64/dovecot/ (I also have mail_plugin_dir = /usr/lib64/dovecot in 10-mail.conf) I enable this plugin in /etc/dovecot/conf.d/20-imap.conf with: protocol imap { mail_plugins = $mail_plugins foo } But … nothing happens. No warnings, no errors, no crashes. How do I debug this? Am I missing something obvious? Does the naming of the plugin matter? S.

Misleading error message when case-insensitive file/dir names from config files clash with case-sensitive file system.
by Info Akra 30 Aug '14

30 Aug '14

Hi, Is it noted somewhere that Dovecot (v 2.0.9) doesn’t use case in directory names in its config-files? I found that out the hard way (i.e. a week of debugging)!! in /etc/dovecot/conf.d/10-master.conf, the line: unix_listener /var/spool/postOut/auth/dovecot-auth { creates a: Jul 29 22:15:58 server dovecot: master: Error: service(auth): unlink(/var/run/dovecot/) failed: Is a directory but unix_listener /var/spool/postout/auth/dovecot-auth { works just fine (with matching case changes on the directory names themselves). That’s on running on Ubuntu 12.04.4 TLS, standard installation from apt-get, in cooperation with Postfix 2.0.9. — Hugo
