Sieve to process list mail based on list-ID
by ＠lbutlr 17 Feb '18

17 Feb '18

Before I spend a lot of time trying to replicate a procmail script that automatically sorts list mail into mailboxes based on the List-ID header (and possibly some other data) I thought I'd check if someone had already done this for sieve. Basically, what I do now in procmail is 1. Get the listname from the List-ID header (or List-post/List-owner if no ID) 2. check against a list of list-ids and if the ID is not on the list, send it to spamc and put the message (if not spam) in the INBOX but mark it as seen, otherwise put it in Junk. 3. have some list specific rules (like rewriting reply-to, stripping subjected tags, etc. 4. Drop message in mailbox based no the ID. (so, dovecot mail goes into .dovecot/new but RandomFakelist gets scanned for spam and if it passes, marked read and put in the inbox). I've seen things like: if exists "List-Id" { if header :contains "List-Id" "dovecot.dovecot.org" { fileinto "dovecot"; } elsif header :contains "List-Id" "others-list.example.com" { fileinto "other-list"; } But I am looking for something more generic, along the lines of $myLists = {"dovecot", "postfix", "other-list") if header :contains "List-ID" "<([^\.])+." { $myID $1; } if $myList :contains $myID { if { $myID is other-list { set $myID to Olist; set header "reply-to" to "moderator@users+other@foo.example.net"; } fileinto $myID; } else { send message to spamc and await results; if spam {fileinto "Junk";} else {fileinto "INBOX";} (obviously that's not the code, but it should give an idea of the sorts of things I want to do and would rather not entirely duplicate. Obviously, I don't know if sieve does variables at all (none of the few example scripts I've looked at have them, but then again most procamil scripts don't have them either). Does sieve support that sort of matching?

`mail_crypt` Doesn't Appear to be Working
by jordan.h＠startmail.com 17 Feb '18

17 Feb '18

Dovecot version: 2.2.22 (fe789d2) I generated an EC key from the page https://wiki2.dovecot.org/Plugins/. For reference here's my /etc/dovecot/conf.d/10-mail-crypt.conf file: ---- mail_plugins = $mail_plugins mail_crypt plugin { # mail_crypt_global_private_key = </etc/dovecot/ecprivkey.pem mail_crypt_global_public_key = </etc/dovecot/ecpubkey.pem mail_crypt_save_version = 2 } ---- I saw in a previous message on this mailing list that messages can be encrypted without the private key, so it's stored elsewhere. :-) After restarting dovecot and sending myself a message I found that the message was still unencrypted. Nothing in /var/log/dovecot/*.log files or syslog indicated any problem loading the plugin (I even made some mistakes with the filename beforehand, and errors indicated it was trying to find the plugin). In case in matters dovecot was installed as part of the automated iredmail install (https://iredmail.org) I didn't modify the dovecot.conf file after installation (except for thinking I needed to add `mail_crypt` to `plugins`, then figuring I didn't). Any help is appreciated. Thank you.

Director & Master Users

Hello, I have Director setup to proxy requests to backend servers. This works fine when using "standard" username/passwords. I am not try to enable the use of the Dovecot Master user through Director into the backend servers. a.) username is being sent as masteruser*username b.) request hits the proxy and authenticates, and then is passed to the backend servers and fails auth. - logs from proxy/Director point of view. auth: Info: passwd-file(masteruser,172.31.33.224,master,<z2eYD0Rl6P+sHyHg>): Master user logging in as devteam imap-login: Info: proxy(devteam): Login failed to backend.servers:143 (master masteruser): [AUTHENTICATIONFAILED] Authentication failed.: user=<devteam>, method=PLAIN, rip=172.31.33.224, lip=192.168.71.20, session=<z2eYD0R l6P+sHyHg> - logs from backend server point of view. imap-login: Info: Disconnected (auth failed, 1 attempts in 2 secs): user=<masterusername>, method=PLAIN, rip=192.168.71.20, lip=192.168.71.99, session=<O8QN8kNlloXAqEcU> Proxy/Director Configs (hopefully this is enough) auth_master_user_separator = * passdb { driver = passwd-file args = /etc/dovecot/conf.d/master-user-password master = yes pass = yes } passdb { driver = static args = proxy=y nopassword=y } Please let me know if I can provide any further details.

Selective authentication mechanism
by Brian Topping 16 Feb '18

16 Feb '18

Hi all! I have been using GSSAPI authentication method for all my externally reachable endpoints for some time under the theory that they cannot be hit with a dictionary attack. Unfortunately, this means iOS devices cannot log in since they (oddly) cannot use GSSAPI. I say “oddly” because desktop Mac mail can use GSSAPI just fine and https://samuelyates.wordpress.com/2013/10/11/kerberos-single-sign-on-in-ios… goes through how to set it up for web pages. In any event, what I’m looking to do is use a filter (https://wiki.dovecot.org/ConfigFile#Filters) around the auth_mechanisms such that it will allow plain authentication when the client is on a local network or the VPN. Unfortunately, the fine print on filters says "These filters work for most of the settings, but most importantly auth settings currently only support the protocol filter”. I guess it’s kind of academic, but I thought I’d ask why this is a limitation? If there is not a profound security reason to not support this, is this a good enough use case to consider it? Thanks! Brian

ACLs, shared, public, virtual mailboxes not working
by David Mehler 15 Feb '18

15 Feb '18

Hello, I'm running Dovecot 2.2.3, and am having issues with my public folders, shared folders, and virtual/ALl folders apparently ACLs are on that list as well. I was debugging an unrelated problem with my smtp server and got the following dovecot debug log output. Below is also a doveconf -n output as well as my shared-folder definition file and my global-acls file. What I'm trying to accomplish is: 1. Have a public folder that any user on the system can put messages into and respond to. 2. Have a shared folder in which user1(a)example.com and user1(a)example2.com can exchange messages. 3. For each user on the system give them a Virtual/All folder for *all of their messages. I'd appreciate any help. As an aside if anyone sees an issue with my SSL ciphers list i'd appreciate knowing that as well, in brief I'm trying to get the most secure list, pfs, and not worrying about backware compatibility. If it's not TLS 1.2 I don't touch it. Thanks. Dave.

Segfault on selecting mailbox twice in a row
by John van der Kamp 15 Feb '18

Hi, I was doing some testing with new 2.2 changes. I’m using commit 15d5b8a from origin/master-2.2. The setup is using imapc to connect to a different imap server. If I use the following commands, dovecot will crash every time: A login username password B select inbox C select inbox The logfile snippit is at the end of the mail. Let me know if you need more information.

Re: Problem with CentOS package for 2.3.0 and old dependency in systemd with clean install

Ok thanks, for the moment : can I just delete the lines in the dovecot-init.service file or what is proposed here? It's no problem for me to make the necessary changes I just need to know which of them because I don't know if you just need this fiel internally or not.

doveadm with wildcard users?
by ＠lbutlr 15 Feb '18

# 2.2.33.2 (d6601f4ec): If I do doveadm index -u user "*" for a local user, it works fine, but if I do doveadm -u "*(a)sqldomain.tld" "*" or doveadm -u "*(a)localaliasdomain.tld" "*" or doveadm -u "*(a)localdomain.tld" "*" or doveadm -u "user(a)localdomain.tld" "*" it fails, … -u "user(a)sqldomain.tld" Seems to work <https://wiki2.dovecot.org/Tools/Doveadm/Index> -u user/mask Run the command only for the given user. It's also possible to use '*' and '?' wildcards (e.g. -u *(a)example.org)

Problem with CentOS package for 2.3.0 and old dependency in systemd with clean install
by TG Servers 14 Feb '18

14 Feb '18

Hi, you definitely have a problem with the packages out of your own repo for version 2.3.0 and CentOS. And this is only if you do a clean install, meaning there was no lower dovecot version ever running on the system. If you want to 'systemctl start dovecot' it breaks with a dependency error which comes from dovecot-init.service. dovecot-init.service : [Unit] Description=One-time Dovecot init service ConditionPathExists=|!/var/lib/dovecot/ssl-parameters.dat ConditionPathExists=|!/etc/pki/dovecot/certs/dovecot.pem [Service] Type=oneshot RemainAfterExit=no ExecStart=/bin/sh -c '\ if [ ! -f /etc/pki/dovecot/certs/dovecot.pem ]; \ then\ SSLDIR=/etc/pki/dovecot/ OPENSSLCONFIG=/etc/pki/dovecot/dovecot-openssl.cnf /usr/libexec/dovecot/mkcert.sh /dev/null 2>&1;\ fi;\ if [ ! -f /var/lib/dovecot/ssl-parameters.dat ]; \ then\ /usr/libexec/dovecot/ssl-params >/dev/null 2>&1; \ fi' It wants to call /usr/libexec/dovecot/ssl-params if /var/lib/dovecot/ssl-parameters.dat (which is deprecated now as I understood) is not existing. The problem is in 2.3.0 /usr/libexec/dovecot/ssl-params is not existent anymore. This error does not occur if you for instance install 2.2.x from the base repo, start it once, and then update the version from your repo. This is because the ssl-parameters.dat was created with the old version then. But this should not be the expected behaviour I think. It should be possible to do a fresh install of 2.3.0 on a fresh system. Can you please get back to me on that? Thanks, Thomas
