postmaster_address parameter scope
by mabi 10 Feb '20

10 Feb '20

Hello, I was wondering when I define the following dovecot parameter: postmaster_address = postmaster(a)mydomain.com in my local.conf config file, does this parameter apply globally? I mean because it is not inside any {} curly braces does it also appliy to: protocol lmtp { ... } or do I need o explicitly define again my postmaster_address parameter inside protocol lmtp{} like this? protocol lmtp { postmaster_address = postmaster(a)mydomain.com } My very same question applies also … [View More]

Hello!, I have a dovecot server configured with about 3k different domains. It worked without problems until SSL certificates has been installed. After increase available RAM and stabilizing the service my current problem is in renewals. Dovecot reload process consumes a lot of memory for every one certificate renewal. The server has enough memory to support reload in most cases, but if server has certain load, reload process throws down the service. I’m using lets encrypt certificates and … [View More]

auth-client via SSL?
by Heiko Schlittermann 05 Feb '20

05 Feb '20

Hello, does dovecot support tls-on-connect for AF INET based auth-client sockets? Rationale behind my question: Exim can use the Dovecot auth-client socket to delegate the SMTP-AUTH authentication to Dovecot. Currently Exim supports the AF UNIX only for this socket. Jeremy makes progress in extending this to use AF INET sockets too. While it works with clear text communication already, during testing I was to setup the auch-client socket as an TLS server (tls-on-connect). It doesn't seem … [View More]

Hi, in our setup, we have two SMTP servers: - one for receiving messages (this one is using Dovecot's LMTP for delivery) - one for sending messages (this one is used by our users as outgoing SMTP server) Only the first one has list of local domains, local e-mail accoutns etc. so the second one will ALWAYS use MX records for delivery - with this setup, we can allow to our users to add any domain to their accounts (for example, if someone will add gmail.com and create e-mail … [View More]

mail_filter and mail_filter_out broken somewhere between 2.2.27 and 2.3.4, problem still exists in git
by Michael Fincham 03 Feb '20

03 Feb '20

Hi Dovecot folks, I recently reported this bug in Debian (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=939442) after a stretch -> buster upgrade, however since I can reproduce it using the latest 2.4 from git I thought perhaps I ought to take it straight upstream. Here's the text I provided Debian about the issue, and below that I've included a syslog snip showing the same issue in a fresh build of git master as well. mail_filter_out seems to fully panic (backtrace below), whereas … [View More]mail_filter is just behaving oddly. Thanks :) ***************************** Package: dovecot-core Version: 2.3.4.1-5+deb10u1 Severity: important Hi Dovecot maintainers, After upgrading from the latest stretch version of dovecot-core (2.2.27-3+deb9u5) to buster (2.3.4.1-5+deb10u1) the "mail filter" interface seems to have broken. This problem is also present in the sid version (2.3.7.2-1). Mail filter is used to run the content of messages being stored or retrieved through an arbitrary process. The interface used for the external process is described here: https://wiki.dovecot.org/Plugins/MailFilter It is expected that the process will be called with the arguments specified in the configuration then supplied a message body on stdin, however since upgrading it seems that the arguments are not being correctly passed, instead being all jammed in to $1 and separated by tabs, rather than expanded in to argv. Even stranger the first few lines of the body of the message appear in argv rather than in stdin... These reproduction steps were carried out on a fresh install of Debian Buster with the "dovecot-core" package installed initially from stretch then upgraded to the buster version, however this behaviour has also been observed on stretch systems after upgrading to buster. To reproduce, drop this minimalised config in to /etc/dovecot/conf.d/repro.conf: # Minimal maildir setup for LDA first_valid_uid = 0 mail_location = maildir:~/Maildir userdb { driver = static args = allow_all_users=yes uid=mail gid=mail home=/tmp/%u } # Mail filter configuration mail_plugins = $mail_plugins mail_filter plugin { mail_filter = mail-filter read %u mail_filter_out = mail-filter write %u } service mail-filter { executable = script /usr/local/bin/mail-filter.sh user = dovecot unix_listener mail-filter { mode = 0666 } } And create the example script in /usr/local/bin/mail-filter.sh with executable permissions: #!/bin/bash echo "arguments were: $@" 1>&2 tempfile=$(mktemp) cat > "${tempfile}" cat "${tempfile}" rm "${tempfile}" This script simply logs the arguments it recieves, writes stdin to a file then retrieves it again from the file. Here's a sample session of me using dovecot-lda to pass a message through this script, then retrieve it again with doveadm: root@scratch-b6fd8bdd:~# /usr/lib/dovecot/dovecot-lda -d fincham@scratch-b6fd8bdd -f 'Test <scratch-b6fd8bdd>' < /root/test.eml root@scratch-b6fd8bdd:~# doveadm fetch -u 'fincham@scratch-b6fd8bdd' hdr subject Test hdr: To: Test <fincham@scratch-b6fd8bdd> From: Test <fincham@scratch-b6fd8bdd> Subject: This is the test e-mail root@scratch-b6fd8bdd:~# tail /var/log/syslog | grep mail-filter Sep 5 00:07:48 scratch-b6fd8bdd dovecot: mail-filter: Error: arguments were: write fincham@scratch-b6fd8bdd Sep 5 00:07:50 scratch-b6fd8bdd dovecot: mail-filter: Error: arguments were: read fincham@scratch-b6fd8bdd However after upgrading dovecot to the buster version this process no longer works, and the logged argv of the example script is very strange: root@scratch-b6fd8bdd:~# apt dist-upgrade Reading package lists...

Sieve prevents tigger of quota-warning
by Tom Sommer 31 Jan '20

31 Jan '20

Hi All I have a few reports from Sieve users, that they are not receiving quota warnings. It appears that when a mailbox is reaching quota, and sieve is responsible for moving mail the mail due to a rule, the quota-warning directive is not triggered? It works fine if Sieve is not part of the flow, and lmtp is alone in handling mail saving. Does anyone have a fix or insights into this? 2.3.9.2 Thanks -- Tom

Split storage & solr
by Daniel Miller 30 Jan '20

30 Jan '20

Is it possible to setup the following: 1. Primary mailserver with SMTP solutions and Dovecot. 2. Primary server will store recent mails. 3. Secondary server for archival storage and Solr. So I'm not looking for a distributed cluster - simply a splitting of designated functions. Clients would only be connecting to the primary server. I know Dovecot supports an alternate storage location - that's what made me think this was possible. What I'm more uncertain of is Solr. My (probably flawed) … [View More]

Dovecot authentication through proxy
by Daniel Niewerth 28 Jan '20

28 Jan '20

Hi everybody, I run two redundant Dovecot servers with a shared Maildir on a GlusterFS volume and a SQL authentication backend based on a mirrored MariaDB database. Because of the splitbrain situation I would like to add two Dovecot Director as proxies. Since a few days I am trying to get the setup running. In the meantime I have achieved that the clients can successfully authenticate on the proxy and that the client connections are forwarded to the backend servers. Unfortunately I still … [View More]have the problem that no authentication attempts are made on the backend servers. Can someone explain me how to solve this problem? I have read that it is eventually possible to work with Master Users. But I guess that won't work for me, because I use the mailcrypt plugin and the client password is also the password for the encryption key.

Number of imap-login processes always keeps growing, never goes down
by Jasper Siepkes 26 Jan '20

26 Jan '20

Hi all! I've bumped into an issue which Dovecot which has me a bit stumped; All of a sudden (ie. no obvious changes made to the config as far as I know) Dovecot seems to never stop 'imap-login' processes. This continues to the point where it will hit the 'process_limit'. For a 50-ish user install the limit was set to 100 but I increased it to 512. The only thing this changes it that Dovecot takes a little longer to hit the limit. I started having this problem with Dovecot version 2.3.2.1. … [View More]After which I updated to the latest version of Dovecot (2.3.9.2) to see if that would fix my problem. However I'm still experiencing the same issue. For a bit of context; We use Dovecot with Open-Xchange where users login via OIDC, get a token and then use that token with Dovecot with the 'oauthbearer' auth method. However users can also login via a username / password combo stored in LDAP for clients that don't support 'oauthbearer' (ie. about all the mail clients ;-). We run Dovecot on SmartOS (ie. Illumos, a Solaris derivative). Oddly enough 'doveadm' is under the impression there are only 3 users loggedin (when there are 512 imap-login processes). I think 'doveadm who' doesn't show users who are authenticated via an token (oauthbearer) because I only see 3 users and I don't see my own user which is logged in via Open-Xchange by using oauthbearer as auth method. I've anonimized the output but you get the idea: ----8<-------------------- # doveadm who username # proto (pids) (ips) foo1(a)foo.nl 2 imap (78393 78391) (52.XXX.XXX.XXX) foo2(a)foo.nl 2 imap (72548 72547) (52.XXX.XXX.XXX) foo3(a)foo.nl 2 imap (480893 481231) (54.XXX.XXX.XXX 54.XXX.XXX.XXX) ----8<-------------------- I don't know if the above issue is related to my problem but the oauthbearer sessions not showing up seems like a bug? Meanwhile there are 512 Dovecot imap-login processes: ----8<-------------------- # ptree | grep imap-login | wc -l 513 ----8<-------------------- I realise that the 'imap-login' process also works as a IMAP proxy and that it stays alive during the entire session of the client since it handles the TLS part of the connection. However there are nowhere near 512 connections active. As far as I know IMAP doesn't support multiplexing (ie. multiple IMAP sessions in a single TCP connection) so with 512 imap-login proccess I would expect to see a lot more connections then I'm seeing: ----8<-------------------- #

Lookup master userdb used with GSSAPI causes auth-worker to report "Error: BUG: PASSL had invalid passdb ID"
by Filip Matijević 25 Jan '20

25 Jan '20

Hello to everybody, I'm in the process of setting up test mail server (Ubuntu 19.10 amd64 running as VM under Hyper-V) and got stuck on configuring master user authentication. I use GSSAPI authentication in parallel with PLAIN/LOGIN (pam backend that authenticates against my Active Directory domain) and this works as intended. I then tried adding simple static master passdb that simply returns nopassword='y' and k5principals=... for test and it also works OK. Sadly, using any other backend (I'… [View More]

sieve size match with multiple of 4GB not matching (BUG?)

Hi, I have noticed a strange behaviour when using size matches with GB in sieve. If I use filter that matches mails smaller then 4, or 8GB it does not match in any case. same filter matches with 3,5,6,7 GB example filter: require "vnd.dovecot.debug"; if allof (size :under 4G) { debug_log "MATCH"; } else { debug_log "NO MATCH"; } # sieve-filter -u johnd filter.sieve INBOX >> Filtering message: ID: <5167DFC8.8040207@XXXXXX> Date: Fri, 12 Apr 2013 12:… [View More]

wrong Messages in virtual Folder
by Frank-Ulrich Sommer 24 Jan '20

24 Jan '20

Hello, I created a virtual Folder that should contain all Mails from several different Folders and their subfolders. Recently I added a new folder to the dovecot-virtual file and then found that most Mails from this folder were missing. I always restartet dovecot (is this necessary?) after any change. The system is running Debian Stretch and I am using the supplied dovecot 2.2.7 (see below for output of doveconf -n). To narrow this down I removed all other directories from the dovecot-virtual … [View More]file and then found that the number of mails is correct, but most mails are the wrong ones from other directories. The dovecot-virtual file currently contains only the source directory and in the last line 4 spaces followed by the keyword "all" and a newline. Mails that where moved there after the directory was added to the virtual folder seemed to be displayed correct. If I move one Mail away from the source diectory a totally different Mail in the virtual Folder disappers. After moving the file back to the source folder it correctly appears in the virtual folder. What might be the cause and how can I fix it? Thanks, Frank Output of "doveconf -n": # 2.2.27 (c0f36b0): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.16 (fed8554) # OS: Linux 4.9.0-11-amd64 x86_64 Debian 9.11 zfs auth_verbose = yes log_path = /var/log/dovecot.log mail_location = maildir:/home/bananamail/Maildir:INDEX=/var/dovecot_indexes/%u mail_plugins = " virtual fts fts_solr" mailbox_list_index = yes managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext namespace { location = virtual:~/Maildir/virtual prefix = _virtual. separator = . type = private } 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 = } passdb { args = scheme=CRYPT username_format=%u /etc/dovecot/users driver = passwd-file } plugin { fts = solr fts_autoindex = yes fts_enforced = yes fts_solr = break-imap-search url=http://localhost:8080/solr/ sieve = file:~/sieve;active=~/.dovecot.sieve } postmaster_address = postmaster@localhost protocols = imap service imap-login { inet_listener imaps { port = XXXX ssl = yes } } ssl = required ssl_cert = <XXXXXXXXX/fullchain.pem ssl_cipher_list = ALL:!LOW:!SSLv2:!SSLv3:!EXP:!aNULL ssl_dh_parameters_length = 2048 ssl_key = # hidden, use -P to show it ssl_protocols = !SSLv3 !TLSv1 userdb { args = username_format=%u /etc/dovecot/users driver = passwd-file } protocol imap { mail_max_userip_connections = 200 } [View Less]
