v2.2.19 released

http://dovecot.org/releases/2.2/dovecot-2.2.19.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.19.tar.gz.sig * pop3_deleted_flag has been broken since v2.2.10. Using it would cause buffer overflows, which could be exploitable. However, this bug would have become visible quite soon after users had deleted some POP3 mails, because the pop3 processes would have started crashing all the time even in normal use. * "doveadm director flush" command has a changed meaning now: It safely moves users to their wanted backends, instead of simply forgetting the mapping entirely and leaving the existing connections untouched. Use -F parameter to get the original unsafe behavior. + Added imap-hibernate processes (see imap_hibernate_timeout setting). IDLEing IMAP connections can be hibernated, which saves memory. + Optimized tracking mailboxes' vsizes (= sum of all messages' sizes). If mailbox_list_index=yes, it's also stored in there. This makes it very efficient to look up vsizes for all mailboxes. + Added a quota "count" backend, which uses the mailbox vsizes to get the current quota usage. It requires using the new quota_vsizes=yes setting, which tracks the messages' "virtual sizes" rather than "physical sizes". Their distiction is minor and mostly irrelevant nowadays (if mail sizes should be counted with LF or CRLF newlines). + "doveadm director up/down" commands added. The monitoring script should be using these commands instead of changing the vhost count. This allows admin to manually disable a server by changing the vhost count to 0 without the monitoring script changing it back. + Added support for HAProxy protocol: http://wiki2.dovecot.org/HAProxy + Added push-notification plugin framework, which can be used to easily implement push notifications to various backends. Implemented "ox" backend for notifying Open-Xchange via HTTP/json. + imap_logout_format supports more variables now, e.g. number of deleted messages. + pop3: Added pop3_delete_type setting (related to pop3_deleted_flag). + plugin { fts_enforced=yes } setting now fails body searches unless it can be done via the full text search engine. + Added %{passdb:*} and %{userdb:*} variables to various places + auth: Added ":protected" suffix for passdb and userdb fields. If used, the field doesn't overwrite an existing field. + IMAP/POP3 proxy: If a backend server dies, avoid client reconnection spikes by slowly disconnecting clients over time. This is enabled by setting login_proxy_max_disconnect_delay=secs passdb extra field. + imap: Added new read-only METADATA entries: /private/specialuse, /shared/comment, /shared/admin + imap: If client disconnects in the middle of a command, log how long the command had been running. - mdbox: Rebuilding could have caused message's reference count to overflow the 16bit number in some situations, causing problems when trying to expunge the duplicates. - Various search fixes (fts, solr, tika, lib-charset, indexer) - Various virtual plugin fixes - Various fixes and optimizations to dsync, imapc and pop3-migration - imap: Various RFC compliancy and crash fixes to NOTIFY

Re: dovecot quota service for postfix
by Michael Peter 03 Oct '15

Hello, Thanks for the clarifications plugin { quota = maildir:User quota quota_rule = *:storage=1G quota_grace = 10%% # 10% is the default quota_status_success = DUNNO quota_status_nouser = DUNNO quota_status_overquota = "552 5.2.2 Mailbox is full" } The above configurations is my default for all users. but my mail system is using mbox format and not maildir.... so what should i change in the above configuration to use mbox INSTEAD of maildir ?? Also for the quota paramater, can i use (myquota = maildir:User quota) INSTEAD of (quota = maildir:User quota) ?? or it must "QUOTA =" and not any thing else to work ? same for quota_rule parameter, should i add (_rule) after quota to work ??? can i add for example qouta_restriction INSTEAD of quota_rules ?? i am asking this question to better understand how dovecot work.. also last question when i use the following command to get quota for existing system user called michael , it gives me an error as follow, so why dovecot is not able to get the quota for the system users? doveadm quota get -u michael doveadm(michael): Fatal: User doesn't exist Many thanks >> Incase user is underquota, then the email is returned back to postfix for >> processing and delivering email to user mbox, incase user has no sufficient quota then dovecot will inform postfix to reject email. Please confirm if what i mentioned above is correct and that i >> understand >> correctly how dove-cot policy works with postfix. > Your understanding is mor or less correct, except that postfix never passes the email itself to dovecot when performing the quota check. It simply sends a message to the quota policy service asking if the recipient is over quota. If the recipient is over quota, dovecot provides postfix with the response configured in quota_status_overquota. If the recipient is under quota, dovecot provides postfix with the response configured in quota_status_success. If dovecot does not know the user, it provides postfix with the response configured in > quota_status_nouser. >> Kindly check my configuration below and advise the missing parts to add... > I don't see anything wrong with your configuration on first appraisal, but if it isn't working I would recommend you perform the following troubleshooting steps. > 1.

imap_logout_format improvements / ideas
by Timo Sirainen 03 Oct '15

03 Oct '15

http://hg.dovecot.org/dovecot-2.2/rev/93bba97afb2a http://hg.dovecot.org/dovecot-2.2/rev/e0a17714f0c9 So all in all, you can now add to imap_logout_format: # %i - total number of bytes read from client # %o - total number of bytes sent to client # %{fetch_hdr_count} - Number of mails with mail header data sent to client # %{fetch_hdr_bytes} - Number of bytes with mail header data sent to client # %{fetch_body_count} - Number of mails with mail body data sent to client # %{fetch_body_bytes} - Number of bytes with mail body data sent to client # %{deleted} - Number of mails where client added \Deleted flag # %{expunged} - Number of mails that client expunged # %{trashed} - Number of mails that client copied/moved to the # special_use=\Trash mailbox. Any thoughts on what else would be useful? I was also thinking about separating (deletes and) expunges from Trash vs non-Trash, but I'm not sure how useful that would be (and what would it be called?) It's also a bit annoying that a copy+expunge to a Trash will return expunged=1 trashed=1, but a move to Trash (via IMAP MOVE) will return expunged=0 trashed=1. But trying to fix that would be too much trouble.

/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.
