Managing Sieve on macOS 10.12 Sierra with Server 5.2?
by Gerben Wierda 17 Dec '16

17 Dec '16

I don’t know if this is considered OT, but dovecot has support for sieve. I had a rule set running under Mac OS X 10.8.5 Server 2.2.5 which I did maintain by hand on the server because a while before Mac OS X Server had dropped support for Squirrelmail. Now I wonder if there is a decent way to get sieve running again on macOS 10.12 Sierra with Server 5.2 G

Existing shared mailbox ... does not exist
by Ruga 17 Dec '16

17 Dec '16

Hello, Dovecot 2.2.26.0 Thunderbird 45.4.0 ESR Scenario: We have a shared mailbox with e-mails in its subdirectories. There are no e-mails in the shared mailbox itself. Example: /Shared <----------------------------------- empty /Shared/call_for_papers <-------------- empty /Shared/call_for_papers/AAMAS <-- populated ...more of the same... Problem: When selecting /Shared, Thunderbird chirps this message: "The current operation on 'Shared' did not succeed. The mail server for account @example.com responded: Mailbox doesn't exist: Shared/Shared (0.000 + 0.000 secs)."

service(indexer-worker): child 18977 killed with signal 11 (core dumped)

Hello to everybody, first of all: thanks a lot for your hard work and for this nice piece of software! After many search about the following SIGSEGV, I decide to post the backtrace and I hope to have avoided duplicated thread. The problem arise after I enable clucene fts. I tryed the clucene ports version (I am using OpenBSD) and a fixed version from github (Blue-Rocket/clucene::feature/pod) which contains FreeBSD fixes and others memory leak patches, but the problem persists. I built either dovecot-* and clucene-core with -g and the following logs are taken from that version. Maybe, I can do more debugging but I don't know how; some ideas? thanks a lot == LOG == Dec 16 12:30:34 mail02 dovecot: indexer-worker(user@hostname): Indexed 1 messages in Trash Dec 16 12:31:16 mail02 dovecot: imap-login: Login: user=<user@hostname>, method=PLAIN, rip=10.244.3.101, lip=10.244.3.200, mpid=90234, TLS, session=<68Ny6MRDml8K9ANl> Dec 16 12:31:16 mail02 dovecot: imap-login: Login: user=<user@hostname>, method=PLAIN, rip=10.244.3.101, lip=10.244.3.200, mpid=59810, TLS, session=<c7xz6MRDzV4K9ANl> Dec 16 12:31:16 mail02 dovecot: imap-login: Login: user=<user@hostname>, method=PLAIN, rip=10.244.3.101, lip=10.244.3.200, mpid=66756, TLS, session=<UtNz6MRDiJwK9ANl> Dec 16 12:31:16 mail02 dovecot: imap-login: Login: user=<user@hostname>, method=PLAIN, rip=10.244.3.101, lip=10.244.3.200, mpid=81959, TLS, session=<gJZ06MRD9HQK9ANl> Dec 16 12:31:16 mail02 dovecot: imap-login: Login: user=<user@hostname>, method=PLAIN, rip=10.244.3.101, lip=10.244.3.200, mpid=14099, TLS, session=<BL116MRD3DgK9ANl> Dec 16 12:31:16 mail02 dovecot: indexer-worker(user@hostname): Indexed 1 messages in INBOX Dec 16 12:32:18 mail02 dovecot: indexer-worker: Fatal: master: service(indexer-worker): child 18977 killed with signal 11 (core dumped) == GDB == (gdb) bt #0 strlen () at /usr/src/lib/libc/arch/amd64/string/strlen.S:152 #1 0x0000093434d7c120 in __vfprintf (fp=0x7f7fffff96c0, fmt0=0x9343cef79ae "Timeout leak: %p (%s:%u)", ap=Variable "ap" is not available. ) at /usr/src/lib/libc/stdio/vfprintf.c:885 #2 0x0000093434d9b068 in *_libc_vsnprintf (str=0x933ab0940b8 "Timeout leak: 0x9342f652300", n=120, fmt=0x9343cef79ae "Timeout leak: %p (%s:%u)", ap=0x7f7fffff9870) at /usr/src/lib/libc/stdio/vsnprintf.c:61 #3 0x000009343cdd4aa5 in str_vprintfa (str=0x933ab094078, fmt=0x9343cef79ae "Timeout leak: %p (%s:%u)", args=0x7f7fffff9870) at str.c:129 #4 0x000009343cdaacd1 in internal_handler (ctx=0x9343d22fab0, format=0x9343cef79ae "Timeout leak: %p (%s:%u)", args=0x7f7fffff9870) at failures.c:602 #5 0x000009343cdab839 in i_internal_error_handler (ctx=Variable "ctx" is not available. ) at failures.c:677 #6 0x000009343cdab3f4 in i_warning (format=0x9343cef79ae "Timeout leak: %p (%s:%u)") at failures.c:325 #7 0x000009343cdc107b in io_loop_destroy (_ioloop=Variable "_ioloop" is not available. ) at ioloop.c:741 #8 0x000009343cd485bd in master_service_deinit (_service=Variable "_service" is not available. ) at master-service.c:876 #9 0x0000093193802642 in main (argc=1, argv=0x7f7fffff9b28) at indexer-worker.c:83 (gdb) bt full #0 strlen () at /usr/src/lib/libc/arch/amd64/string/strlen.S:152 No locals. #1 0x0000093434d7c120 in __vfprintf (fp=0x7f7fffff96c0, fmt0=0x9343cef79ae "Timeout leak: %p (%s:%u)", ap=Variable "ap" is not available. ) at /usr/src/lib/libc/stdio/vfprintf.c:885 mbs = { __mbstate8 = "{\t\000\000\000\000\000\000\000\000\000\000r3\t\000\000\000\000\000\000\000\000\000\0004\t\000\000\001\000\000\000\000\000\000\000223\177\177\000\000\001\000\000\000\000\000\000\000\002\000\000\000\000\000\000\000\t216U\035\rP", '\0' <repeats 47 times>, __mbstateL = 10118011532464} mbseqlen = Variable "mbseqlen" is not available. == DOVECONF == #

making a plugin encrypt index data
by micah anderson 16 Dec '16

16 Dec '16

Hello, I'm encrypting mail on disk using a plugin[0], but the index files are not encrypted (specifically the dovecot.index.cache can be read). I want to do is encrypt index on disk, so I'm looking for how a plugin can achieve that by hooking into the right locations. Is that easily possible in a plugin? I can turn off those indexes by passing INDEX=MEMORY, but that isn't possible if I use sdbox/mdbox. thanks for any suggestions! micah 0. https://0xacab.org/riseuplabs/tofu-scrambler

public folder subscriptions sync issue with ldap user/group in dovecot-acl
by Mike Fröhner 16 Dec '16

16 Dec '16

Hello people, I am having an issue with 'doveadm sync'. I am currently trying to have two dovecots behind an haproxy (works fine). Therefore I configured these two dovecot server (imap-1/imap-2) to sync throught dsync. This works just partly. The sync of the maiboxes is fine, but the sync of the subscriptions file just works partly. It works for private folder subscription, but not completly for public folder subscription. I found two issues, if I am using LDAP (user/groups) in dovecot ACLs. 1. I would like to subscribe 2 public folder (public/test/test1 and public/test/test2). My user (ldaptestuser) is an ldap user and this user is member of the ldap group (ldaptestgroup) which does have all dovecot-acl rights on these folders. imap-1 # cat /opt/mail/_public/publictest/.test*/dovecot-acl group=ldaptestgroup akxeilprwts group=ldaptestgroup akxeilprwts I am now connecting with my mail client to imap-1 (throught haproxy) and the subscription to this folder works. The file which is written looks like: imap-1 # cat /opt/mail/ldaptestuser/Mails/subscriptions Sent publictest/test/test1 publictest/test/test2 Now I am awaiting the synch to imap-2, but the file which it written looks like: imap-2 # cat /opt/mail/ldaptestuser/Mails/subscriptions Sent If I modify the dovecot-acl for .test1 to imap-1 # cat /opt/mail/_public/publictest/.test1/dovecot-acl group=ldaptestgroup akxeilprwts user=ldaptestuser akxeilprwts and execute the subscription again - the synced file looks like: imap-2 # cat /opt/mail/ldaptestuser/Mails/subscriptions Sent publictest/test/test1 The subscription of public folder test2 will also been synced, if I add my ldaptestuser to the acl file for this folder. 2. Another issue is to unsubscribe a public folder. If I unsubscribe folder test1, it is written to subscriptions file on the imap where I am connected, but it is NOT synced even if my user and group are configured at the dovecot-acl file. If I then unsubscribe a not public folder (like Sent), the former unsubscribed folder test1 is (faulty) subscribed again. But both imap do have the same subscriptions for my ldaptestuser user. I do have the behavior with dovecot-2.2.26 and dovecot-2.2.27 on CentOS-7 (selinux disabled). If you need more information like the dovecot -n or some other stuff give me a short notice. Mike;

autoexpunge=30d does not works :(
by Peter Hodur 16 Dec '16

16 Dec '16

Hello, just upgraded to Dovecot 2.2.27 and altered dovecot.conf to contain autoexpunge directive for Spam mailbox (yes it's migrated from Courier 3 years ago): namespace inbox { prefix = INBOX. separator = . inbox = yes mailbox Archive { auto = subscribe special_use = \Archive } mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Spam { auto = subscribe special_use = \Junk autoexpunge = 30d } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } } As I hope, when user logout (POP3 or IMAP) or after Postfix delivers mail via LMTP, Dovecot should check Spam folder for emails, which have ctime older than 30 days and deletes this emails. Recently I have tried this. I have tried login / logout and nothing happend. I have tried turning log verbosity to debug but I can not find any note in debug.log according to this. I would like to kindly ask someone for which this directive works to help me, what is wrong with my config or how can I debug it and find error. Thanks Pete

Possible solr and indexing bug
by Netfront Customer Service 16 Dec '16

16 Dec '16

Bug Report: We had one of our solr server down for a while, then observed a lot of "Warning: fscking index file " actions. Version 2.2.27 with auto fsck. A follow up investigation shows direct one to one relationship between solr error and subsequent fscking. The fscking lasts for quite a long time (for at least an hour) when the mailbox is concurrently accessed. Thank you.

Configuration problem for secure virtual server
by Karsten Malcher 15 Dec '16

15 Dec '16

Hello, i want to configure a virtual mailsystem on an debian server with exim and dovecot. Because it is running on a V-Server, i want to store everythink in a LUKS encrypted contrainer. So i created a group crypt with the members Debian-exim (107), dovecot, (other users with encrypted content) All mails should be stored in /mail in the mounted container. Dovecot has this configuration: ======================================= passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf } userdb { driver = static args = uid=Debian-exim gid=mail home=/mountpoint/mail/%d/%n } mail_uid = Debian-exim first_valid_uid = 107 last_valid_uid = 107 first_valid_gid = 8 last_valid_gid = 9 mail_location = maildir:/mountpoint/mail/%d/%n ======================================= The /mountpoint has the following rights: drwxrwx--- 5 root crypt 4,0K Dez 13 19:05 mountpoint The subdirectories are all owned by Debian-exim: drwxrwx--- 4 Debian-exim mail 4,0K Okt 23 17:05 mail The group mail has id 8 and the group crypt has id 9 The Problem is that dovecot will not go into the directory with group crypt! I always get the following error message: Dec 15 18:03:25 pop3(karsten@server): Error: user karsten@server: Initialization failed: Initializing mail storage from mail_location setting failed: stat(/mountpoint/mail/server/karsten) failed: Permission denied (euid=107(Debian-exim) egid=8(mail) missing +x perm: /mnt, we're not in group 9(crypt), dir owned by 0:9 mode=0770) Dec 15 18:03:25 pop3(karsten@server): Error: Invalid user settings. Refer to server log for more information. But dovecot is definitely in the group crypt! What i am doing wrong? Regards Karsten
