"mail_shared_explicit_inbox = no", but shared INBOX has a "\Noselect" tag?
by Rudolf Körner 08 Feb '16

08 Feb '16

Regarding the given information, it seems to me that the option "mail_shared_explicit_inbox=no" does not work as expected. Quote from NEWS-2.2: mail_shared_explicit_inbox setting to specify if a shared INBOX should be accessible as "shared/$user" or "shared/$user/INBOX" Using Dovecot 2.2.13 and Maildir++ Working on the commandline: # doveconf mail_shared_explicit_inbox mail_shared_explicit_inbox = no # service dovecot restart # ls -lda /mail/reader/Shared/owner(a)example.com/.* Shows no (hidden) folders. # telnet 127.0.0.1 143 a0 login reader(a)example.com *** a1 list "" "Shared/owner(a)example.com" * LIST (\Noselect \HasChildren) "/" Shared/owner(a)example.com a1 OK List completed. Is the retrieved "\Noselect" tag correct with the option "mail_shared_explicit_inbox = no"? I would expect the folder "Shared/owner(a)example.com" to be "selectable", because I thought the option "mail_shared_explicit_inbox = no" would make e-mails of a shared INBOX visible directly at the folder "Shared/owner(a)example.com" (which does not work in my case). Note: Shared *sub*folders of an INBOX work as expected. Just to show that the shared INBOX is accessible (note that it is not shown by a list "" "*" here, which is expected with that option): a2 list "" "Shared/owner(a)example.com/INBOX" a2 OK List completed. a3 select Shared/owner(a)example.com/INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 27 EXISTS Using "mail_shared_explicit_inbox = yes" does show the INBOX as a subfolder of "Shared/owner(a)example.com" and allows accessing the e-mails of the shared INBOX. However, it would be nice (and keep users happy at using their known shared folder layout) to see the e-mails of the shared INBOX at the Shared/owner(a)example.com folder.

Send Dovecot logs to rsyslog
by Nicolas Fo 08 Feb '16

08 Feb '16

Hello, I'm trying to send Dovecot logs to a Graylog server. To do this, I'd like to pass logs to rsyslog and rsyslog pass logs to remote Graylog server. I set in dovecot.conf : syslog_facility = local5.info I set in rsyslog.conf : local5.info @192.168.xxx.xxx:5555 Restarted services and it doesn't work. I use nmap to test if port 5555 is opened and this port is open. What missed I ? Thanks Nicolas

simple bind + X.509 client certificate?
by Heiko Schlittermann 05 Feb '16

05 Feb '16

Hi, using dovecot 2.2.9. The LDAP server requests a client certificate from dovecot. This client certificate will not be used for authentication, but anyway, the server requests it. No SASL is involved. ldapsearch and Exim work as expected, sending the client cert. The slapd is configured: olcTLSVerifyClient: demand For authentication simple bind should be used. Dovecot doesn't seem to send the requested client certificate. If I sniff the connection, the "Certificate" sent to the server is empty. Using ldapsearch it works (and the certificate isn't empty). Any suggestions?

doveadm backup -- private flags in shared mailbox
by almut bertha 05 Feb '16

05 Feb '16

dear list, i try to backup our dovecot server via doveadm -Dv backup -A -n inbox -n shared remote:vmail@192.168.122.51 So far, it's working fine except for one thing: the "seen"flags for the shared mailboxes don't get copied to the backup-server. I tried a few things (like calling the doveadm command with different options for the namespaces or defining the mailboxes -m; i also changed the path for INDEXPVT), but none of these worked and i don't know how to tell doveadm to sync these flags. Maybe the config for the namespaces is wrong? Or is it just not possible (yet)? thanks in advance The configs for the source and the backup server are the same: (except for hostname, ip,...) # 2.2.18: /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.8 (0c4ae064f307+) # OS: Linux 4.3.0-1-amd64 x86_64 Debian stretch/sid ext4 auth_verbose = yes default_client_limit = 2500 default_process_limit = 500 disable_plaintext_auth = no doveadm_port = 11111 lmtp_rcpt_check_quota = yes lmtp_save_to_detail_mailbox = yes mail_location = maildir:/srv/vmail/%n/Maildir mail_plugins = " acl quota" managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate imapflags notify namespace { hidden = no inbox = no list = children location = maildir:/srv/vmail/%%n/Maildir:INDEXPVT=/srv/vmail/%n/shared/%%n prefix = shared.%%n. separator = . subscriptions = no type = shared } namespace inbox { hidden = no ignore_on_failure = no inbox = yes list = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = INBOX. separator = . subscriptions = yes type = private } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile:/etc/dovecot/global-acls:cache_secs=300 acl_shared_dict = file:/var/lib/dovecot/db/shared-mailboxes.db mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename quota = maildir:User quota:noenforcing quota_grace = 2%% quota_rule = *:storage=3G sieve = /srv/vmail/%Ln/default.sieve sieve_default = /srv/vmail/default.sieve sieve_dir = /srv/vmail/%Ln/sieve sieve_extensions = +notify +imapflags sieve_global_dir = /srv/vmail/global.sieve/ } postmaster_address = postmaster(a)mur.at protocols = " imap lmtp sieve pop3" quota_full_tempfail = yes service auth { unix_listener auth-userdb { group = vmail mode = 0777 user = vmail } } service lmtp { inet_listener lmtp { address = 192.168.122.52 port = 24 } user = vmail } service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieve_deprecated { port = 2000 } process_min_avail = 1 service_count = 1 vsz_limit = 64 M } service managesieve { process_limit = 256 } userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } userdb { args = /etc/dovecot/dovecot-ldap-group-userdb.conf.ext driver = ldap } protocol lmtp { mail_plugins = " acl quota sieve" } protocol imap { mail_max_userip_connections = 16 mail_plugins = " acl quota imap_acl imap_quota" } protocol sieve { managesieve_implementation_string = Dovecot Pigeonhole } protocol pop3 { mail_plugins = " acl quota" }

Authentication proxy
by Miecio 05 Feb '16

05 Feb '16

Hello everyone! I need to set up kind of gateway for submission and imap request, in order to do that i need to find out solution for verifying user password against multiple IMAP backends. Everything for IMAP proxy works perfectly. But i have a problem with authenticating postfix against dovecot SASL. I wonder if there is any option in dovecot to authenticate SASL requests (from postfix) against remote IMAP server or remote SASL instance. Problem is that this server has to be chosen dynamically on the user name basis, so i have to overwrite somehow host parameter in passdb imap definition. I was thinking about using two separate password databasases, first configured as normal sql lookup with proxy flag and host field and second as imap database with host changed to some parameter matching host from previous lookup. Problem is that i don't see any variable matching host filed from passwd sql lookup. With this approach other problem appears, because I want user to be always authenticated against remote IMAP/SASL so i have to somehow return PASSWORD_MISMATCH from my sql lookup. I tried setting up deny parameter to my sql lookup but it causes to reject whole authentication request without even asking remote imap. Thanks a lot --- Regards Miecio

external storage for mail attachments
by zucca＠systemschmiede.com 03 Feb '16

03 Feb '16

Hi list! was wondering if it was possible to store mail attachments on a separate storage with dovecot, and if so, how. Of course a single instance storage of these attachments would also be a very good thing, allthough not a basic prerequisite.

Apply modifier on long_name variables
by Leon Kyneur 03 Feb '16

03 Feb '16

Hi, Wondering why it's not possible to do the following in ldap args file: base = ou=People,dc=%Ddomain_first,o=ISP however this does work: base = ou=People,dc=%Dd,o=ISP is it intentional that modifiers do not work on long names? Thanks Leon
