Why does Dovecot authentication against Openldap fail when using TLS encryption?
by Dimitri KOPRIWA 29 Jun '17

29 Jun '17

Dear Mailing list, I have a Dovecot v2.2.9 server that authenticate against a Openldap server. I want to configure Dovecot to use TLS for LDAP authentication. I have tried to fetch/send emails using Thunderbird: - IMAP succeed to fetch mail - SMTP failed to send mail The Dovecot server produce the following log : Jun 29 08:44:00 mail postfix/submission/smtpd[634]: connect from virtual.domain.com[172.16.0.1] Jun 29 08:44:01 mail dovecot: auth: Debug: auth client connected (pid=0) Jun 29 08:44:02 mail dovecot: auth: Debug: client in: AUTH#0111#011PLAIN#011service=smtp#011nologin#011lip=172.17.0.15#011rip=172.16.0.1#011secured#011resp=<hidden> Jun 29 08:44:02 mail dovecot: auth: Debug: ldap(me(a)domain.com,172.16.0.1): bind search: base=dc=mail,dc=domain,dc=com filter=(&(objectClass=CourierMailAccount)(mail=me(a)domain.com)) Jun 29 08:44:02 mail dovecot: auth: Debug: ldap(me(a)domain.com,172.16.0.1): no fields returned by the server Jun 29 08:44:02 mail dovecot: auth: Debug: ldap(me(a)domain.com,172.16.0.1): result: uid missing Jun 29 08:44:02 mail dovecot: auth: Debug: client passdb out: OK#0111#011user=me(a)domain.com Jun 29 08:44:04 mail postfix/submission/smtpd[661]: connect from mail.node.domain-ovh.consul[172.16.0.2] Jun 29 08:44:04 mail postfix/submission/smtpd[661]: lost connection after CONNECT from mail.node.domain-ovh.consul[172.16.0.2] Jun 29 08:44:04 mail postfix/submission/smtpd[661]: disconnect from mail.node.domain-ovh.consul[172.16.0.2] Jun 29 08:44:07 mail dovecot: auth: Debug: auth client connected (pid=662) Jun 29 08:44:07 mail dovecot: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=172.16.0.2, lip=172.17.0.15, TLS handshaking: Disconnected, session=<MGK6TRVTRACsEAAC> **Note that before I switch to use TLS**, the server was doing clear connection to Openldap and the **binding was working fine**.

localhost logins
by Daniel Miller 27 Jun '17

27 Jun '17

While auditing my logs after an account was compromised, I see a number of entries like: Jun 23 11:32:18 bubba dovecot: auth: ldap("one-of-my-accounts",127.0.0.1): invalid credentials I'm trying to figure out where this login attempt is coming from. I do run ASSP (an SMTP proxy) on this server, as well as Postfix - but I wouldn't think there'd be any communication with Dovecot for those? Postfix does use Dovecot SASL - but I see separate log entries for Postfix authentication failures. There are of course plenty of external IP's listed in Dovecot logs - I'm just asking for possible causes for the localhost entries. -- Daniel

Released Pigeonhole v0.4.19 for Dovecot v2.2.31.
by Stephan Bosch 26 Jun '17

26 Jun '17

Hello Dovecot users, Here's the definitive 0.4.19 release. There is one additional fix. Changelog v0.4.19: * This release adjusts Pigeonhole to several changes in the Dovecot API, making it depend on Dovecot v2.2.31. Previous versions of Pigeonhole will produce compile warnings with the recent Dovecot releases (but still work ok). - Fixed bug in handling of implicit keep in some cases. Implicit side-effects, such as assigned flags, were not always applied correctly. This is in essence a very old bug, but it was exposed by recent changes. - include extension: Fixed segfault that (sometimes) occurred when the global script location was left unconfigured. The release is available as follows: https://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.19.t… https://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.19.t… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

v2.2.31 released
by Timo Sirainen 26 Jun '17

26 Jun '17

https://dovecot.org/releases/2.2/dovecot-2.2.31.tar.gz https://dovecot.org/releases/2.2/dovecot-2.2.31.tar.gz.sig This should be a great and stable release for the summer :) v2.2.32 is planned for the end of August. Hopefully soon afterwards we can get back to v2.3. * LMTP: Removed "(Dovecot)" from added Received headers. Some installations want to hide it, and there's not really any good reason for anyone to have it. + Add ssl_alt_cert and ssl_alt_key settings to add support for having both RSA and ECDSA certificates. + dsync/imapc, pop3-migration plugin: Strip trailing whitespace from headers when matching mails. This helps with migrations from Zimbra. + acl: Add acl_globals_only setting to disable looking up per-mailbox dovecot-acl files. + Parse invalid message addresses better. This mainly affects the generated IMAP ENVELOPE replies. - v2.2.30 wasn't fixing corrupted dovecot.index.cache files properly. It could have deleted wrong mail's cache or assert-crashed. - v2.2.30 mail-crypt-acl plugin was assert-crashing - v2.2.30 welcome plugin wasn't working - Various fixes to handling mailbox listing. Especially related to handling nonexistent autocreated/autosubscribed mailboxes and ACLs. - Global ACL file was parsed as if it was local ACL file. This caused some of the ACL rule interactions to not work exactly as intended. - auth: forward_* fields didn't work properly: Only the first forward field was working, and only if the first passdb lookup succeeded. - Using mail_sort_max_read_count sometimes caused "Broken sort-* indexes, resetting" errors. - Using mail_sort_max_read_count may have caused very high CPU usage. - Message address parsing could have crashed on invalid input. - imapc_features=fetch-headers wasn't always working correctly and caused the full header to be fetched. - imapc: Various bugfixes related to connection failure handling. - quota=imapc sent unnecessary FETCH RFC822.SIZE to server when expunging mails. - quota=count: quota_warning = -storage=.. was never executed - quota=count: Add support for "ns" parameter - dsync: Fix incremental syncing for mails that don't have Date or Message-ID headers. - imap: Fix hang when client sends pipelined SEARCH + EXPUNGE/CLOSE/LOGOUT. - oauth2: Token validation didn't accept empty server responses. - imap: NOTIFY command has been almost completely broken since the beginning. I guess nobody has been trying to use it.

ACL problems on shared folder
by Thomas Robers 26 Jun '17

26 Jun '17

Hello, I've a Dovecot Server Version 2.2.30.2 running on CentOS 6.9 and there's a problem with acls on shared folder. We have some mailboxes which are shared and used as a "group mailbox" and also some user who share their inbox and only the inbox when they are on holiday e.g.. When I set "acl_defaults_from_inbox = yes" it's not possible to restrict the access to only the inbox, meaning that the user who wants to share only their inbox have to share the whole mailbox. On the other hand when I set "acl_defaults_from_inbox = no" it is not possible to create a folder direct under the inbox of a "group mailbox" and one gets a "permission denied" message. Is this the normal behavior normal? Although the user who wants to create the folder has all rights he gets a "permission denied" message? Why? Am I missing something important? Does anyone who uses shared mailboxes had the same problem and solved this? Any suggestion or information, that I probably miss is welcome.

Courier migration to dovecot
by j.emerlik 23 Jun '17

23 Jun '17

Hi, I'm almost ready to migrate Courier to Dovecot 2.2.31 but I have one question about home and mail directory. It's good idea to have same directory form home and mail ? Which scenerio will be better and why ? For example: A) Home: /home/doamin/user1 Mail: /home/doamin/user1 B) Home: /home/doamin/user1/home Mail: /home/doamin/user1 C) Home: /home/doamin/user1/ Mail: /home/doamin/user1/mail Thanks & regards, Jack
