haproxy + submission services -> postfix failure
by Chris Thomas 24 Apr '19

24 Apr '19

Hi, I have a nginx server which is using the proxy protocol to forward tcp connections to dovecot. Dovecot is configured to be a submission service for email to be sent. Then postfix should send the email itself which is also using the ha proxy protocol. There are a few moving parts in this problem so I'm not sure where the problem is. But I want to ask if somebody can validate my dovecot configuration somehow so I can start to tick off some things from the list. Sending email fails, seems to get to postfix, then die Receiving emails succeeds and I don't have any problem to pick them up. I've figured out some stuff, like lmtp shouldn't use haproxy when talking between postfix -> dovecot for receiving emails. If I enable the protocol on lmtp, I can't receive any emails at all. In order to get postfix to accept emails, I enabled haproxy protocol and enabled postscreen and then postfix could access the source ip and stop my server from being an open relay. I've got tls certificates installed on dovecot and postfix, all created by letsencrypt and I don't appear to have any problems with them. I will try to give as much information about the config as I can, I'm not sure what other parts are good to have, but let me know if you are missing something or want to check a value. >> 10-master.conf: service submission-login { inet_listener submission { port = 587 haproxy = yes } } service lmtp { inet_listener lmtp { port = 24 haproxy = no } } >> 20-submission.conf submission_relay_host = postfix.mail-server submission_relay_port = 25 submission_relay_ssl = starttls submission_relay_ssl_verify = yes Then because it might help to give the other side of the connection configuration for postfix, here is the relevant information: >> master.cf: smtp inet n - - - 1 postscreen smtpd pass - - - - - smtpd >> main.cf postscreen_upstream_proxy_protocol = haproxy postscreen_upstream_proxy_timeout = 10s That's it. I don't know what other information could be useful. There are some logs, they are like this (I've got logging turned on for pretty much every option I have: Dovecot logs: Apr 19 17:54:47 submission(__EMAIL__)<497><KUGA0OWG8XlfW/Q8>: Debug: Added userdb setting: plugin/quota_rule=*:bytes=0 Apr 19 17:54:47 submission(__EMAIL__)<497><KUGA0OWG8XlfW/Q8>: Debug: Effective uid=8, gid=8, home=/mail/__DOMAIN_COM__/__USER__ Apr 19 17:54:47 submission(__EMAIL__)<497><KUGA0OWG8XlfW/Q8>: Debug: Namespace inbox: type=private, prefix=, sep=, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:/mail/__DOMAIN_COM__/__USER__ Apr 19 17:54:47 submission(__EMAIL__)<497><KUGA0OWG8XlfW/Q8>: Debug: maildir++: root=/mail/__DOMAIN_COM__/__USER__, index=, indexpvt=, control=, inbox=/mail/__DOMAIN_COM__/__USER__, alt= Apr 19 17:54:47 submission(__EMAIL__)<497><KUGA0OWG8XlfW/Q8>: Debug: smtp-server: conn __IP_ADDR_1__:31217 [0]: Connection created Apr 19 17:54:47 submission(__EMAIL__)<497><KUGA0OWG8XlfW/Q8>: Debug: smtp-client: conn postfix.mail-server:25 [0]: Connection created Apr 19 17:54:47 submission(__EMAIL__)<497><KUGA0OWG8XlfW/Q8>: Debug: smtp-client: conn postfix.mail-server:25 [0]: Looking up IP address Apr 19 17:54:47 submission(__EMAIL__)<497><KUGA0OWG8XlfW/Q8>: Debug: smtp-client: conn postfix.mail-server:25 [0]: DNS lookup successful; got 1 IPs Apr 19 17:54:47 submission(__EMAIL__)<497><KUGA0OWG8XlfW/Q8>: Debug: smtp-client: conn postfix.mail-server:25 [0]: Connecting to 10.104.211.161:25 Apr 19 17:54:47 submission(__EMAIL__)<497><KUGA0OWG8XlfW/Q8>: Debug: smtp-client: conn postfix.mail-server:25 [0]: Connected Apr 19 17:54:57 submission(__EMAIL__)<497><KUGA0OWG8XlfW/Q8>: Debug: smtp-client: conn postfix.mail-server:25 [0]: Received greeting from server: 421 4.3.2 No system resources Apr 19 17:54:57 submission(__EMAIL__)<497><KUGA0OWG8XlfW/Q8>: Debug: smtp-client: conn postfix.mail-server:25 [0]: Connection failed: 421 4.3.2 No system resources Apr 19 17:54:57 submission(__EMAIL__)<497><KUGA0OWG8XlfW/Q8>: Error: Failed to establish relay connection: 421 4.3.2 No system resources Apr 19 17:54:57 submission(__EMAIL__)<497><KUGA0OWG8XlfW/Q8>: Debug: smtp-client: conn postfix.mail-server:25 [0]: Disconnected Apr 19 17:54:57 submission(__EMAIL__)<497><KUGA0OWG8XlfW/Q8>: Info: Disconnect from __IP_ADDR_1__: Failed to establish relay connection in=0 out=22 (state=GREETING) Apr 19 17:54:57 submission(__EMAIL__)<497><KUGA0OWG8XlfW/Q8>: Debug: smtp-server: conn __IP_ADDR_1__:31217 [0]: Disconnected: Failed to establish relay connection Postfix Logs: postfix/postscreen[525]: warning: haproxy read: time limit exceeded If anybody could help out, I'd be grateful because I just can't see what the problem is.

lmtp_save_to_detail_mailbox override
by Andreas Thienemann 24 Apr '19

24 Apr '19

Hi, I have a dovecot 2.3.2.1 instance running here that is getting userdb and passdb data from a SQL database. This was a cyrus server migrated over and all users are happy. All users except one: Said user asked if it would be possible to disable subaddressing (localuser+folder(a)example.com) again. The setting controlling that is AFAIK the lmtp_save_to_detail_mailbox item. My idea was to override that setting for the specific user. I changed the user_query to return no for the user in question and all seems well: # doveadm user test field value user test(a)example.com uid vmail gid vmail home /var/lib/imap/example.com/test mail mdbox:/var/spool/imap/user/example.com/test lmtp_save_to_detail_mailbox no # Looks good, doesn't work though. Mail is still delivered to the +folder. Is this per user setting not taken into account? I could probably provide the user in question with a sieve script that files everything into the INBOX again but I wonder if there's a better way? cheers, Andreas

FTS delays
by Joan Moreau 21 Apr '19

21 Apr '19

Hi When I do a FTS search (using Xapian plugin) in the BODY part, the plugins returns the matching IDs within few milliseconds (as seen in the log). However, roundcube (connected on dovecot) takes ages to show (headers only vie IMAP) the few results (I tested with a matching requests of 9 emails) What could be the root cause ? Thank you

Extended logging / moved mails jumping back
by Martin Müller 20 Apr '19

20 Apr '19

Hi! About 4-6 MUA Thunderbird 60.6.1 are going to connect with dovecot 2.2.13/IMAP (debian 8) and are using the same user/password. This setup works for years flawless (updated clients and serversoftware). Since a few weeks there is one major trouble: I one of the client moves a mail from the inbox to a another IMAP-Folder, most of the moved mail are moved for the moment. But an unstable period later, the mails are moved back to the inbox. In rarely cases, the moved mail is copied (one in the inbox, one in the destinationfolder). Now I have to check, if this a Thunderbird-Issue or is this a dovecot-issue. For that reason, I will activate the extended logging of dovecot. ### ### ### ### dovecot -n # 2.2.13: /etc/dovecot/dovecot.conf # OS: Linux 3.16.0-6-amd64 x86_64 Debian 8.11 auth_mechanisms = plain login debug_log_path = /var/log/mail.dovecot-debug disable_plaintext_auth = no info_log_path = /var/log/mail.dovecot-info listen = *,[::] log_path = /var/log/mail.dovecot-error log_timestamp = "%Y-%m-%d %H:%M:%S " mail_debug = yes mail_max_userip_connections = 100 mail_privileged_group = vmail passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size quota = dict:user::file:/var/vmail/%d/%n/.quotausage sieve = /var/vmail/%d/%n/.sieve sieve_max_redirects = 25 } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail mode = 0600 user = vmail } user = root } service imap-login { client_limit = 1000 process_limit = 512 } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } ssl_cert = </etc/postfix/smtpd.cert ssl_key = </etc/postfix/smtpd.key ssl_protocols = !SSLv3 userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota pop3_uidl_format = %08Xu%08Xv } protocol lda { mail_plugins = sieve quota postmaster_address = postmaster(a)monarch.products4more.at } protocol lmtp { mail_plugins = quota sieve postmaster_address = postmaster(a)monarch.products4more.at } ### ### ### ### ### ### ### ### It works: dovecot logs to three differnt logfiles /var/log/mail.dovecot-* It doesnt work: plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size } I cant see such events in the logfiles.

Does anyone know if the use of LMTP (or even the dovecot LDA) still loses the x-original-to header that the postfix vda adds and that I rely heavily on (since I use a lot of aliases), and if it does, is there any solution to get the original recipient added back in before final delivery? Everything I'm reading says that LMTP is better, but I really do need this header (or one like it) to be there so I know who the original recipient was (for filtering and other purposes).

v2.3.5.2 released
by Aki Tuomi 18 Apr '19

18 Apr '19

Lets try again, put wrong changelog to the mail. Sorry about this. https://dovecot.org/releases/2.3/dovecot-2.3.5.2.tar.gz https://dovecot.org/releases/2.3/dovecot-2.3.5.2.tar.gz.sig Binary packages in https://repo.dovecot.org/ * CVE-2019-10691: Trying to login with 8bit username containing invalid UTF8 input causes auth process to crash if auth policy is enabled. This could be used rather easily to cause a DoS. Similar crash also happens during mail delivery when using invalid UTF8 in From or Subject header when OX push notification driver is used. --- Aki Tuomi Open-Xchange oy

Problems with auth connection
by Fernando Ortega 18 Apr '19

18 Apr '19

Hi, We are having some issues with the auth connection Version: 2.3.5.1, with MySQL and Postfix The server is working fine, and randomly after some days, Dovecot fails to auth: Apr 18 14:25:16 mail dovecot[25013]: auth: Warning: Event 0x126eba20 leaked (parent=0x126eb820): auth-request.c:89 Apr 18 14:25:16 mail dovecot[25013]: auth: Warning: Event 0x126eb420 leaked (parent=0x0): auth-client-connection.c:338 It's neccesary to restart dovecot, and once restarted the server start to work fine again and deliver emails What do you think i could do? Thank you, best regards Fernando

CVE-2019-10691: JSON encoder in Dovecot 2.3 incorrecty assert-crashes when encountering invalid UTF-8 characters.
by Aki Tuomi 18 Apr '19

18 Apr '19

Dear subscribers, we're sharing our latest advisory with you and would like to thank everyone who contributed in finding and solving those vulnerabilities. Feel free to join our bug bounty programs (open-xchange, dovecot, powerdns) at HackerOne. You can find binary packages at https://repo.dovecot.org/ Yours sincerely, Aki Tuomi Open-Xchange Oy Open-Xchange Security Advisory 2019-04-18 Product: Dovecot Vendor: OX Software GmbH Internal reference: DOV-3173 (Bug ID) Vulnerability type: CWE-176 Vulnerable version: 2.3.0 - 2.3.5.1 Vulnerable component: json encoder Report confidence: Confirmed Researcher credits: cPanel L.L.C. Solution status: Fixed by Vendor Fixed version: 2.3.5.2 Vendor notification: 2019-04-02 Solution date: 2019-04-11 Public disclosure: 2019-04-18 CVE reference: CVE-2019-10691 CVSS: 7.5 (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) Vulnerability Details: JSON encoder in Dovecot 2.3 incorrecty assert-crashes when encountering invalid UTF-8 characters. This can be used to crash dovecot in two ways. Attacker can repeatedly crash Dovecot authentication process by logging in using invalid UTF-8 sequence in username. This requires that auth policy is enabled. Crash can also occur if OX push notification driver is enabled and an email is delivered with invalid UTF-8 sequence in From or Subject header. In 2.2, malformed UTF-8 sequences are forwarded "as-is", and thus do not cause problems in Dovecot itself. Target systems should be checked for possible problems in dealing with such sequences. See https://wiki.dovecot.org/Authentication/Policy for details on auth policy support. Risk: Determined attacker can prevent authentication process from staying up by keeping on attempting to log in with username containing invalid UTF-8 sequence. Steps to reproduce: Configure dovecot with auth_policy_server_url and auth_policy_hash_nonce set. Attempt to log in with username containing an invalid UTF-8 sequence Observe assert-crash in dovecot logs. Solution: Operators should update to the latest Patch Release or disable auth policy support.

Documentation update
by azurit＠pobox.sk 18 Apr '19

18 Apr '19

Hi guys, this page needs to be updated: https://wiki2.dovecot.org/MailLocation/Maildir#Control_files (link was from here: https://wiki2.dovecot.org/MailLocation) Section 'Control files' is mentioning only 2 files but, in fact, Dovecot will store some additional files in CONTROL location: dovecot-uidvalidity dovecot-uidvalidity.* subscriptions (anything more?) Even more, page https://wiki2.dovecot.org/MailLocation has missing note to CONTROL files location about storing files 'dovecot-uidlist' and 'dovecot-keywords' of INBOX inside .INBOX directory instead of root directory (as it's stored inside mailbox). Missing anything from above will cause re-downloading of all e-mails by e-mail clients! And finally, i'm attaching a Python script which will safely copy/move CONTROL files from mail_location to new location (btw, moving it on SSD storage caused quite high performance boost in our environment). azur

Fwd: SOLR/Index?

forgot to reply all. ---------- Forwarded message --------- From: Larry Rosenman <larryrtx(a)gmail.com> Date: Mon, Apr 15, 2019 at 5:58 AM Subject: Re: SOLR/Index? To: John Fawcett <john(a)voipsupport.it> the local users (myself, my wife, a friend) can authenticate EITHER as <username> or <username>@lerctr.org. switching to all virtual users is NOT going to happen. If I login to roundcube with <user>@lerctr.org it finds the autoindexed mail. So, if I make everyone always authenticate as <user>@lerctr.org we should be fine. and change my script to do doveadm -u <user>@<domain> instead of depending on the local user running the cron job. question: Is there some way to have dovecot change what it sees to be <user>@lerctr.org when they login as <user>?

rsync sdbox, no new mails?
by Jakob Curdes 15 Apr '19

15 Apr '19

Hello, I had to restore a mailserver from a backup to replace a system with problems that is still live. I did a 1:1 restore as far as possible from a backup, then rsynced the /var/vmail/ directory, where we have all the mailboxes, in sdbox format. So both directories should be the same. After syncing, I started dovecot. I can see the mails until to the point of the backup, but not the newer ones ,although they seem to be present in the "cur" directory. I thought with sdbox it is all in the index files that have been transferred with the mails? Or am I missing a place that has to be synced? Thank you for hints, Jakob
