by Aidar Kamalov 20 Oct '17

20 Oct '17

Hello! I setup quota and quota warnings for my mail system(dovecot+exim). By I want to reject only outgoing messages if quota exceeded. Is it possible to congi dovecot to not reject incoming messages? I use dovecot-lda for mail delivery. ldap_delivery: driver = pipe command = /usr/lib/dovecot/deliver -d "${lookup ldap{user=**********))(mai -f $sender_address -a $original_local_part@$original_domain message_prefix = message_suffix = delivery_date_add envelope_to_add return_path_add log_output return_output user = mail group = mail temp_errors = 64 : 69 : 70: 71 : 72 : 73 : 74 : 75 : 78 -- Aydar A.

Dovecot >=2.2.29 + Filesystem quota = incorrect storage information
by Macka 18 Oct '17

Hi, I have problem with quota storage information in dovecot-2.2.29 (and newer versions, too - 2.2.30.2). I use FS quota backend. ............................ # 2.2.29.1 (e0b76e3): /etc/dovecot/dovecot.conf # OS: Linux 4.4.68-1 x86_64 mail_plugins = quota plugin { quota = fs:User quota:mount=/poczta:user quota2 = fs:Group quota:mount=/poczta:group } protocol imap { mail_max_userip_connections = 10 mail_plugins = "imap_quota mail_log notify antispam" } ................................. After upgrade from 2.2.27 to 2.2.29 (newest 2.2.30.2 too), dovecot returns incorrect informations about quota storage: # doveadm quota get -u myusername Quota name Type Value Limit % User quota STORAGE 10960896 100000 10960 or # ( echo "A1 GETQUOTAROOT INBOX"; echo "A2 logout" ) | /usr/lib64/dovecot/imap -u myusername * PREAUTH [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS BINARY MOVE NOTIFY SPECIAL-USE QUOTA] Logged in as myusername imap(myusername): Info: Logged out in=31 out=588 * QUOTAROOT INBOX "User quota" * QUOTA "User quota" (STORAGE 10960896 100000) A1 OK Getquotaroot completed (0.001 + 0.000 secs). * BYE Logging out A2 OK Logout completed (0.001 + 0.000 secs).

Replication between different versions of dovecot
by Dmitry Nezhevenko 18 Oct '17

18 Oct '17

Hi, Can't find any notes about this in documentation. Is replication supposed to work between different versions of dovecot? I've just found that dovecot 2.2.33.1 was uploaded to debian unstable and it crashes on every replication with older dovecot 2.2.27. (version 2.2.32.1 was probably ok) Summary: - 2.2.33.1 crashes when replicating from/to 2.2.27 - 2.2.32.1 probably ok when replicating from/to 2.2.27 I was able to capture backtrace of crashed doveadm-server: Program terminated with signal SIGSEGV, Segmentation fault. #0 i_stream_next_line (stream=stream@entry=0x0) at istream.c:428 428 istream.c: No such file or directory.

You're probably solving the wrong problem -- the mail client really ought to be able to process 300+ messages. It may be a better use of time to fix that than to torture dovecot to give you what you want. You can try using a plugin to define a virtual INBOX https://wiki.dovecot.org/Plugins/Virtual with search/selection criteria to limit the number of messages. You can also try some LDA script (e.g. procmail) hackery to create INBOX volumes of 300 messages, then do some shuffling around when the INBOX gets emptied. Joseph Tam <jtam.home(a)gmail.com>

mdbox + director + nfs
by Raymond Sellars 17 Oct '17

17 Oct '17

Hi Matt We've been running this configuration for the past couple of years. Not noticed any locking issues. As I understand it that's the objective of using Director. As Aki notes make sure you have the appropriate NFS settings. Other lessons we encountered. Important to ensure NFS is NTP sync'd and aligned with your hosts, we hit some issues with file timestamps leading to problems. Replication, e.g. for perhaps a backup or DR site. Seems to work but we've had the odd occasion of the indexes drifting. Never tracked the reason down and believe its unrelated to the NFS. Just something to monitor.

Dovecot 2.2.31 Incorrect Search
by Siarhei Chystsiakou 17 Oct '17

17 Oct '17

Hi. I have installed dovecot 2.2.31 and fts plugin with Apache Solr 6.6.1. I have found that imap search is not correct in my dovecot. For example, I want to find email from user s.chistiakov(a)example.com. I run IMAP command "SEARCH FROM s.chi" and result is null. But if I run IMAP command "SEARCH FROM s.chistiakov" I get list of emails from this user. Why does this happen and how to fix it? Help me please ) Thanks. Result of my actions in telnet: https://hastebin.com/fewanacafu.md Dovecot config: https://hastebin.com/noqehimaxu.makefile
