The left angle bracket at the beginning of the certificate path
by Илья 22 Dec '16

dovecot 2.2.27 (c0f36b0) openSUSE Tumbleweed x86_64 https://forums.opensuse.org/showthread.php/521796-Dovecot-doveconf-Fatal-ex… Faced with an unpleasant situation, when ssl_client_ca_file options are specified path to the left angle bracket, as in options ssl_key ssl_cert ssl_ca path is so. This doveconf shows no syntax error, and the arrow moves to managesieve which there generally is not involved in any side. dovecot: doveconf: Fatal: execvp(/usr/lib/dovecot/managesieve) failed: Argument list too long dovecot: config: Error: managesieve-login: dump-capability process returned 89 I consider this a bug, and that it should not be. And explain why you need left angle brackets in the options ssl_key ssl_cert ssl_ca?

doveadm acl set negative rights not supported?
by Peter Benko 21 Dec '16

21 Dec '16

Hi all, I'm trying to set an ACL with negative rights. I have no problems setting it with standard IMAP commands, but I'm unable to do it with the doveadm acl command. I tried: sudo -u vmail doveadm acl set -u "user@domain" Spam user="-user@domain" lookup (notice the "-" before the username) Unfortunately, this adds a (positive) ACL for the user named "-user@domain" instead of adding a negative one for the user "user@domain". Am I messing up something or is negative ACL support missing from doveadm? I have not seen anything in the docs about this... Regards, Peter

unexpected behaviour of search queries with mixed AND and OR
by Juergen Raschke 20 Dec '16

20 Dec '16

Hello, I found out an unexpected behaviour of search queries with mixed "AND" and "OR". With search query "$ condA OR condB condC $" I get an error: Fatal: Use parenthesis when mixing ANDs and ORs if I switch left and right OR-part and use the query "$ condB condC OR condA $" I get a result, but it is not the expected result of the query "$ \( condB condC $ OR condA \)" I get the result of the query "$ condB OR condC OR condA $" which is more then suprising. The query "$ condB condC OR condA $" should either throw an error like "$ condA OR condB condC $" or deliever the result of "$ \( condB condC $ OR condA \)" Example: doveadm -f flow fetch -u USER guid $ savedbefore 21d OR seen savedbefore 5d $ | wc -l Fatal: Use parenthesis when mixing ANDs and ORs 0 doveadm -f flow fetch -u USER guid $ seen savedbefore 5d OR savedbefore 21d $ | wc -l 63690 doveadm -f flow fetch -u USER guid $ seen OR savedbefore 5d OR savedbefore 21d $ | wc -l 63690 doveadm -f flow fetch -u USER guid $ \( seen savedbefore 5d $ OR savedbefore 21d \) |wc -l 63247 doveadm -f flow fetch -u USER guid $ savedbefore 21d OR \( seen savedbefore 5d $ \) |wc -l 63247 doveconf -n # 2.2.24 (a82c823): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.9 (357ac0a0e68b+) # OS: Linux 3.16.0-0.bpo.4-amd64 x86_64 Debian 7.9 Mit freundlichen Gruessen, Juergen Raschke -- Mittwald CM Service GmbH & Co.

Upgrade from version 1 to 2

19 Dec '16

Hi All I am upgrading from dovecot-1.2.17 to dovecot2-2.2.27_4. I configured version 2 from scratch. I have email in the maildir format. Would it be ok in theory if I simply copy over the email files from the version 1 server to the version 2 server or are there any hidden dangers here? Any problems with indexing? Thanks for any advice

Renumbering UID on messages
by Ricardo Branco 19 Dec '16

19 Dec '16

I am having a problem with Horde due to large variations in email UID for a few users. At one time they were receiving thousands of emails a day, they have deleted all these messages but because they still have early emails in the mailbox the UID range from start to now is massive. We use Horde webmail and it creates an internal array based on range of messages but due to large UID range it eats though the ram. If I use dsync on a mailbox will the UIDs be renumbered? -- The information contained in or attached to this email is intended only for the use of the individual or entity to which it is addressed.

RFC 3501 violation in FETCH BODY responses
by Guilhem Moulin 18 Dec '16

18 Dec '16

Hi there, Quoting RFC 3501 sec. 7.4.2 “FETCH Response” (data item BODYSTRUCTURE): “A body type of type MESSAGE and subtype RFC822 contains, immediately after the basic fields, the envelope structure, body structure, and size in text lines of the encapsulated message.” According the ABNF (RFC 3501 sec. 9) the envelope structure is that of the ENVELOPE FETCH data item, and the env-{from,sender,reply-to,to,cc, bcc} fields are non-space-separated address lists: body-type-msg = media-message SP body-fields SP envelope SP body SP body-fld-lines envelope = "(" env-from SP … SP env-to SP … ")" env-from = "(" 1*address ")" / nil env-to = "(" 1*address ")" / nil While this is indeed the case for ‘FETCH … (ENVELOPE)’, for ‘FETCH … (BODY)’ dovecot 2.2.25 adds a space between addresses of an address list of the envelope structure of an encapsulated MESSAGE/RFC822 message. See the attached patch to ‘src/lib-imap/test-imap-bodystructure.c’, which currently (2.2.25) fails as follows test-imap-bodystructure.c:122: Assert failed: strcmp(str_c(str), testmsg_body) == 0 test-imap-bodystructure.c:129: Assert failed: strcmp(str_c(str), testmsg_bodystructure) == 0 imap bodystructure parser ............................................ : FAILED because the ‘env-to’ field of the envelope structure of the encapsulated MESSAGE/RFC822 message is printed as ((NIL NIL "sub-to1" "domain.org") (NIL NIL "sub-to2" "domain.org")) while it should be ((NIL NIL "sub-to1" "domain.org")(NIL NIL "sub-to2" "domain.org")) After a quick look at the source, this seems to be due to src/lib-imap/imap-bodystructure.c:imap_write_list, which always separates list items with spaces. In the case of an envelope, only the top-level list should be space-separated. Indeed, not adding a space between items of type IMAP_ARG_LIST in the recursive call makes the test pass again. Cheers, -- Guilhem.

Error while migrating mailbox with 'doveadm sync'
by Zhang Huangbin 18 Dec '16

18 Dec '16

Dear all, I successfully migrated hundreds of mailboxes with Dovecot 2.2.24 on OpenBSD 6.0 (amd64. Old server is OpenBSD 5.1, i386, Dovecot-2.0.17), but got error while migrating 3 mailboxes: # doveadm -o mail_fsync=never sync -1 -R -s '' -u user(a)domain.com imapc: dsync(user(a)domain.com): Panic: file mailbox-alias-plugin.c: line 77 (mailbox_symlink_exists): assertion failed: (ret > 0) Abort trap Same error while running ‘doveadm … backup …'. What does this error actually mean? How can i fix it? - Here’s full log running doveadm with ‘-D’ option: http://pastebin.com/Um5fbuNM - ‘dovecot -n’ on old server: http://pastebin.com/4E6xzFKU - ‘dovecot -n’ on new server: http://pastebin.com/4uHwQnMN I checked release notes of Dovecot 2.2.25/26/27, there’re 3 fixes related to 'doveadm sync’, but not sure whether it helps fix this issue. 2.2.26: + doveadm sync/backup: Added -I <max size> parameter to skip too large mails. + doveadm sync/backup: Fixed -t parameter and added -e for "end date”. 2.2.27: - doveadm sync -1: Fixed handling mailbox GUID conflicts.

Antispam plugin: insufficent error messages
by Volker Wysk 18 Dec '16

18 Dec '16

Hi! "Dovecot always logs a detailed error message if something goes wrong. If it doesn't, it's considered a bug and will be fixed." (http:// wiki2.dovecot.org/Logging) I'm trying to set up a spam filter with dovecot-antispam and dspam as backend. When I move a spam message from INBOX to Spam, I get this in syslog: Nov 28 21:15:58 desktop imap: antispam: mailbox_is_unsure(Spam): 0 Nov 28 21:15:58 desktop imap: antispam: mailbox_is_trash(INBOX): 0 Nov 28 21:15:58 desktop imap: antispam: mailbox_is_trash(Spam): 0 Nov 28 21:15:58 desktop imap: antispam: mail copy: from trash: 0, to trash: 0 Nov 28 21:15:58 desktop imap: antispam: mailbox_is_spam(INBOX): 0 Nov 28 21:15:58 desktop imap: antispam: mailbox_is_spam(Spam): 1 Nov 28 21:15:58 desktop imap: antispam: mailbox_is_unsure(INBOX): 0 Nov 28 21:15:58 desktop imap: antispam: mail copy: src spam: 0, dst spam: 1, src unsure: 0 There are no log entries about how dspam is called, or what goes on. Indeed, dspam doesn't get called at all. I know, because I've examined the antispam- plugin source code. There would be a log message if dspam was called. It's hard to study the source code, because there are hardly any comments. I have been able to trace the problem to function signature_extract_to_list() in signature.c. There, -1 is returned: int signature_extract_to_list(const struct signature_config *cfg, struct mailbox_transaction_context *t, struct mail *mail, struct siglist **list, enum classification wanted) { const char *const *signatures; struct siglist *item; signatures = get_mail_headers(mail, cfg->signature_hdr); if (!signatures || !signatures[0]) { if (!cfg->signature_nosig_ignore) { mail_storage_set_error(t->box->storage, ME(NOTPOSSIBLE) "antispam signature not found"); return -1; /* <-- HERE */ } else { return 0; } } while (signatures[1]) signatures++; item = i_new(struct siglist, 1); item->next = *list; item->wanted = wanted; item->sig = i_strdup(signatures[0]); *list = item; return 0; } So, what's happening is "antispam signature not found". My question: What does this mean? What's going on? My "dovecot -n" output is attached. Bye Volker

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)
by Matteo Biagini 16 Dec '16

16 Dec '16

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

Maildir: do message files need to have a unique name across all directories?
by Gerben Wierda 15 Dec '16

15 Dec '16

While testing a new mail server I created a temporary account and filled its mailbox (Milder, dovecot) with the contents of another account. That means the actual message files in each account have identical names. Is that a problem? (I’m asking because I see some weird behaviour of visible/invisible messages and I wonder if this could have been the reason). G
