[Dovecot] Feature Request doveadm acl command
by Thomas Leuxner 18 May '14

18 May '14

I have switched to global ACLs for public namespaces which eases their administration greately. Now while running housekeeping scripts (e.g. expunge old mails/archive mails etc.) this requires temporary overriding the global ACLs with mailbox specifix ACLs to expunge mails. The scripts would then revoke the temporary changes (delete flags) and the global ACL would take precedence again. Ideally I would want to get rid of the 'dovecot-acl' file after the scripts ran so the global ACL kicks in. … [View More]

[Dovecot] User not found when using shadow for passdb
by John J. Stimson III 17 May '14

17 May '14

I am getting "user unknown" when trying to connect to the dovecot server using IMAP. The client gets an authentication failed message and does not download mail. The host system uses shadow passwords in /etc/shadow. I would like to use the same passwords for IMAP sessions, so I have set the passdb driver to shadow. The system is Slackware, which does not use PAM. Here is the dovecot version and configuration output: # dovecot -n # 2.1.17: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 3.… [View More]

Please try it out! BTW. I've read most of the mails again in Dovecot mailing list, but there are still a few reported bugs I decided to leave until later. Anyway feel free to re-send any bug reports for things that haven't … [View More]been fixed in v2.2.13 yet. * Fixed a DoS attack against imap/pop3-login processes. If SSL/TLS handshake was started but wasn't finished, the login process attempted to eventually forcibly disconnect the client, but failed to do it correctly. This could have left the connections hanging arond for a long time. (Affected Dovecot v1.1+) + mdbox: Added mdbox_purge_preserve_alt setting to keep the file within alt storage during purge. (Should become enforced in v2.3.0?) + fts: Added support for parsing attachments via Apache Tika. Enable with: plugin { fts_tika = http://tikahost:9998/tika/ } + virtual plugin: Delay opening backend mailboxes until it's necessary. This requires mailbox_list_index=yes to work. (Currently IMAP IDLE command still causes all backend mailboxes to be opened.) + mail_never_cache_fields=* means now to disable all caching. This may be a useful optimization as doveadm/dsync parameter for some admin tasks which shouldn't really update the cache file. + IMAP: Return SPECIAL-USE flags always for LSUB command. - pop3 server was still crashing in v2.2.12 with some settings - maildir: Various fixes and improvements to handling compressed mails, especially when they have broken/missing S=sizes in filenames. - fts-lucene, fts-solr: Fixed crash on search when the index contained duplicate entries. - Many fixes and performance improvements to dsync and replication - director was somewhat broken when there were exactly two directors in the ring. It caused errors about "weak users" getting stuck. - mail_attachment_dir: Attachments with the last base64-encoded line longer than the rest wasn't handled correctly. - IMAP: SEARCH/SORT PARTIAL was handled completely wrong in v2.2.11+ - acl: Global ACL file handling was broken when multiple entries matched the mailbox name.

[Dovecot] Broken IMAPS Connects Create Lingering imap-login Processes
by Jochen Bern 14 May '14

14 May '14

Hello everyone, we are running a central server (CentOS 6.5, dovecot-2.0.9-7.el6 with a small patch to disable the IMAP CREATE command, and openssl-1.0.1e-16.el6_5.7) and distribute standard client software to customer( site)s. The clients do IMAPS connects in regular intervals (no IDLE, no lingering logins) and authenticate with certs issued by a dedicated PKI ("auth_ssl_username_from_cert = yes" and a static global password). One of the customers has a major networking problem that hasn't … [View More]been fully analyzed yet. Sniffing his IMAPS connects on the server side, I see no (necessarily fragmented) TLSv1 Client Cert + Key Exchange happen; instead, after ~60s, we receive a single packet with "TLSv1 Certificate Verify, Change Cipher Spec, Encrypted Handshake Message" *and* the TCP FIN+PSH+ACK flags set. The problem I'ld like to ask for help with here is that dovecot's imap-login process doesn't terminate when the FIN is received, or when the IMAP protocol's inactivity timeout is reached, it takes *more than two hours* for it to go away. Because of that, this single client racks up 1100+ processes (counting against dovecot's configured limits), TCP connections, and the associated RAM usage. (Since the client cert is obviously never received, the default mail_max_userip_connections of 10 doesn't come into play, either.) Is there any way - short of hexing a negative feedback loop straight into the iptables - to prevent this kind of buildup? Kind regards, J.

Changelog v0.4.3: * Editheader extension: Made control characters allowed for editheader, except NUL. Before, this would cause a … [View More]

I upgraded 2.1 -> 2.2 something like a week ago because I needed INDEXPVT. Not sure if this crash started immediately or not, noticed it today looking at journalctl. Backtrace http://bpaste.net/raw/181944/ and pasted below. This seems to crash on every IMAP connection made, so any ideas for a possible client-level workaround are quite welcome until dovecot code improves here. root@server ~ $ dovecot -n # 2.2.12:

[Dovecot] IMAP disconnect before greeting / banner
by Benoit Panizzon 12 May '14

12 May '14

Hello We have a server on which we run multiple instances of dovecot. Each instance serving a domain and binding to a specific IP. The whole thing on three servers using the proxy ability and replication of dovecot. Now one domain has more users and we start seeing very strange behaviour. As soon as about 45 users have connected to the imap service ip of that instance, the server accepts the connections and then disconnects without showing the IMAP banner. This happens on all of our … [View More]

[Dovecot] ManageSieve OOM with Huge Folders
by Fabian Peter 12 May '14

12 May '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi all, we're experiencing "Out of Memory" Problems caused by Sieve-Filters delivering mail to huge IMAP folders. From the logs, I'm beginning to think the problem is that the sieve/lmtp process loads the "dovecot.index.cache" file apparently twice into memory to do something with it. We've set our memory limit per process to 256MB - the cache file of the folders we're having issues with is exactly 128MB. Mails coming in that should be filtered … [View More]to these folders are being denied, an error is being logged. Apparently, there would be two easy solutions to this: increasing memory OR decreasing folder size. Both are not possible. Increasing memory just means we will have this issue again in some weeks. Deacreasing mailbox size isn't possible since the folders contain archived system mails from our backend software which need to be kept for a while. Currently, we're creating a new folder each time we reach this limit, but that isn't exactly the best way to go for the future. In the end, the folders are for archiving purposes and therefore should not be managed at all since all this is automated. I hope there's some obvious switch I've just not seen in the config. I actually can't imagine that this is default or wanted behaviour since there must be people with large inboxes and sieve filters that either also have this problem or don't have it since they fixed it. The problem clearly is reproducable. Each time the cache file hits 128MB - which happens at around 200k mails in the folder - (with our current setting of 256MB memory limit per process), things go down and our mailqueues reach 10k undelivered mails within a few hours.

[Dovecot] message-decoder bug for attachments with charset=binary attribute in content-type?
by Robert Wolf 12 May '14

12 May '14

Hello, I have configure dovecot with solr and I wanted to let solr index content of attachments. For testing I have used biabam command line tool to generate emails with attachments. I have found that dovecot with fts_decoder incorrectly decodes these attachments from biabam and therefore pdftotext has reported corrupted PDF. The problem is that biabam generates header with charset=binary and dovecot message decoder tries to process it as UTF8 or non-UTF8 data. ===========================… [View More]================================= --biabam.ZxWVLybiabam.ZxWVLy Content-Type: application/pdf; charset=binary Content-Disposition: attachment; filename="bacula-jobs.pdf" Content-Transfer-Encoding: base64 JVBERi0xLjQKJcfsj6IKNSAwIG9iago8PC9MZW5ndGggNiAwIFIvRmlsdGVy IC9GbGF0ZURlY29kZT4+CnN0cmVhbQp4nF2PT0+EMBDF7/0U7yYYWdqFXdbe 1vgnMXpQezMeClSoQNltweh+egvLyczhN3kz703mCLpioFMtLDoSv2aoHKGo ..... ============================================================ This PDF begins orginal with ============================================================ 0000000: 2550 4446 2d31 2e34 0a25 c7ec 8fa2 0a35 %PDF-1.4.%.....5 0000010: 2030 206f 626a 0a3c 3c2f 4c65 6e67 7468 0 obj.<</Length 0000020: 2036 2030 2052 2f46 696c 7465 7220 2f46 6 0 R/Filter /F 0000030: 6c61 7465 4465 636f 6465 3e3e 0a73 7472 lateDecode>>.str ============================================================ But the dovecot pass following data to fts_decoder script: ============================================================ 0000000: 2550 4446 2d31 2e34 0a25 c3a4 c3bc c3b6 %PDF-1.4.%...... 0000010: c39f 0a32 2030 206f 626a 0a3c 3c2f 4c65 ...2 0 obj.<</Le 0000020: 6e67 7468 2033 2030 2052 2f46 696c 7465 ngth 3 0 R/Filte 0000030: 722f 466c 6174 6544 6563 6f64 653e 3e0a r/FlateDecode>>. ============================================================ As you can see binary data are mangled.

I don't know if this is correct update, but the searching works with this update for biabam binary attachments too. Could you please verify this problem and maybe update the code?

[Dovecot] Segfault with passwd as a second userdb at auth_fields_rollback
by Jan Kończak 11 May '14

11 May '14

Hello, I've been trying to set up dovecot to support passwd-file + passwd/PAM auth. I made an unusual config (passwd-file as userdb failed to work for me), which uses static as userdb: =============== passdb { driver = passwd-file args = username_format=%u scheme=CRYPT /etc/dovecot/users } userdb { driver = static default_fields = uid=vmail gid=vmail home=/var/spool/mail/%d/%n } passdb { driver = pam } userdb { driver = passwd } =============== While passwd-file+static worked … [View More]well, passwd/PAM caused trouble: $ doveadm user xxx doveadm(root): Error: userdb lookup(xxx): Disconnected unexpectedly field value If passwd-file had the user, check went fine; otherwise it segfaulted. The crash has been accompanied by a syslog message: kernel: auth[9788]: segfault at 18 ip 0000000000416391 sp 00007fffd11a3d90 error 4 in auth[400000+44000] Translating address lead me to: 0000000000416390 <auth_fields_rollback>: 416390: 53 push %rbx 416391: 48 83 7f 18 00 cmpq $0x0,0x18(%rdi) I was using packages from http://packages.atrpms.net/dist/el6/dovecot/ To be precise, dovecot-2.2.10-1_14.el6.x86_64.rpm I tampered with the src.rpm, upgraded spec&sources to match 2.2.12. It didn't help, so I tries to "workaround" this. The bug has gone when in src/auth/auth-fields.c:210 I added check if the field ptr is not null. As it's a userdb query, it seems that for some reason (static?) in src/auth/auth-request.c:1058 the function auth_fields_rollback is called with null request->userdb_reply Now it works fine: $ doveadm user xxx field value uid 1000 gid 100 home /home/xxx mail maildir:~/.maildir system_groups_user xxx $ doveadm user jkonczak@ast... field value uid 103 gid 103 home /var/spool/mail/ast.../jkonczak mail maildir:~/.maildir So now virtual users get vmail uid/gid, system users get their uid/gid, home is fine etc. Below I attach the patch + full config.

[Dovecot] ECDSA certificate support
by SIW 11 May '14

11 May '14

Does the latest version of Dovecot support ECDSA certificates? I had a look in: http://wiki2.dovecot.org/SSL but it didn't answer my question. Can someone please help or point me in the right direction? I'd also like to know if I can run an RSA cert AND an ECDSA certificate at the same time in Dovecot (like you can in Postfix). Many thanks.

[Dovecot] dovecot 2.2.9 - ssl_cert and ssl_key ignored
by Alexandru Bostina 11 May '14

Hello, It seems that Dovecot ignores the new /ssl_cert and ssl_key /settings. Using them in the dovecot configuration results in the error: Fatal: Couldn't parse private ssl_key: error:0906D06C:PEM routines:PEM_read_bio:no start line: Expecting: ANY PRIVATE KEY] Using the old /ssl_//cert//_file/ and /ssl_key_file/ results in their being obsolete warning but no fatal error.

[Dovecot] Only part of sieve script works
by Sebastian Schlingmann 10 May '14

10 May '14

Hi, I am using Dovecot 2.2.11 with Pigeonhole on Arch Linux. I have a partly working sieve script (pasted to the end of this mail) which sorts mail into various imap folders. The first, third and fourth if blocks work just fine. The second and fifth block do not sort any mails. However, if I apply the script with sieve-test to mails the second and fifth block seem to work. How is the manual check with sieve-test different from the sieve filtering during mail delivery? I am thankful for any … [View More]

[Dovecot] Denial of Service attacks against Dovecot v1.1+
by Timo Sirainen 10 May '14

10 May '14

There's an upper limit to how many IMAP/POP3 connections can exist that haven't logged in (and separate limits for post-login). Normally when this limit is reached, the oldest connection gets disconnected. There is of course some potential to try to DoS Dovecot by doing a lot of IMAP/POP3 connections, but because the oldest connection always gets destroyed this requires quite a lot of activity from the attacker. This "destroy oldest connection" however hasn't been working in v1.1+ releases for … [View More]

[Dovecot] Disable IMAP for ONE user only

I use MySQL to store my virtual users passwords and I am running the latest version of Dovecot. What I need to do is have one particular user have ONLY access to their email via Roundcube (webmail) and no IMAP/SMTP access. Therefore, how do I disable IMAP/SMTP access for just one user?

[Dovecot] segfault with shared namespace version > 2.1.16
by Tom Lieuallen 08 May '14

08 May '14

We're currently running 2.1.16. I've been wanting to update to a 2.2.X version, but have been running into problems, even with the latest (2.2.12). I'm not sure at what version this issue appeared, but I believe I've tried 2.2.10, 2.2.11, and now 2.2.12. We have a shared maildir setup. With that configuration in place and with a user in the dovecot-acl file, I can do the following to make it segfault every time. Note if I comment out the shared namespace config, it does not segfault. … [View More] /private/dovecot/libexec/dovecot/imap -u tom2 * 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 SPECIAL-USE BINARY MOVE] Logged in as tom2 l list "" * Segmentation fault (core dumped) The /a1 and /a2 mentioned here for shared folders and indexes are both local ext4 file systems. =========== Here is the output of dovecot -n: # 2.2.12: /private/dovecot/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-431.el6.x86_64 x86_64 CentOS release 6.5 (Final) first_valid_uid = 100 listen = * mail_location = mbox:~/mail:INBOX=/var/mail/%u:INDEX=/a2/imap-index/%u mail_plugins = quota acl namespace { hidden = yes inbox = no list = children location = maildir:/a1/dove-shared:INDEX=/a2/imap-index/dove-shared/%u prefix = sharedimap/ separator = / type = shared } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = separator = / type = private } passdb { args = /private/dovecot/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } passdb { args = scheme=CRYPT username_format=%u /private/dovecot/etc/passwd driver = passwd-file } plugin { acl = vfile quota = fs:INBOX:mount=/a1 quota2 = fs:Home quota:mount=%h } protocols = imap lmtp service imap-login { process_limit = 500 process_min_avail = 16 service_count = 1 } service imap { process_limit = 2048 } ssl_cert = </private/ssl/certs/mail.engr.oregonstate.edu.pem ssl_key = </private/ssl/certs/mail.engr.oregonstate.edu.pem userdb { args = /private/dovecot/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } userdb { args = username_format=%u /private/dovecot/etc/passwd driver = passwd-file } ============== I've got core dumps from it.
