Use sieve to move all mail automatically based on List-Id
Dear all,
I currently use the following rule to automatically sort email into
folders based on mailing lists:
# split out the various list forms
# Mailman & other lists using list-id
if exists "list-id" {
if header :regex "list-id" "<([a-z_0-9-]+)[.@]" {
set :lower "listname" "${1}";
fileinto :create "${listname}";
} else {
if header :regex "list-id" "^\\s*
it moves the email to the folder 142 as the regex matches inside the <> string
till the none-letter/none-number/_/- is matching.
I do not understand the expresion [.@] so it is nearly impossible for my to
extend that query.
What I would like to do is using the ID as folder name as fallback.
So in this case I would like that the email is moved to folder
`mfechner/ci-test`.
I'm not sure if sieve can handle the `/` correctly.
Thanks a lot for any tip.
Gruß
Matthias

Can you provide a link? Sure, please see here: https://www.owasp.org/index.php/Password_Storage_Cheat_Sheet And if I was adventurous about hashes, I would be looking more at Keccak.

IMAPSieve message marked as HAM should go through full sieve script of user
Dear all, I use the IMAPSieve implementation described here: https://wiki.dovecot.org/HowTo/AntispamWithSieve It is working really great! Thanks a lot for this. The problem I have now is: A message was by accident marked by rspamd as spam, so a false-positive and is moved to the Junk folder. If I click in my email program now on `Not Spam` it is learn as HAM but moved to the INBOX. I would like that the email is not moved to INBOX but it should be moved through the sieve script of the user again, as it is a new email. Currently I have to mark all false-positives as not spam and have then to manually move it to the correct subfolder which is a bit annoying. Is this possible? Thanks a lot! -- Gruß Matthias

Dovecot uses wrong separator after migration, modify sieve script
Dear all,
I migrated a dovecot installation that was using pam to a virtual setup
where users are stored in a SQL database.
I see that my old pam based installation on the filesystem directories
are starting with a dot.
The new server does not have the leading dot.
So even if the configuration is mostly equal, I cannot find a reason why
dovecot changed its behavior here.
I do not define a separator in the dovecot configuration and the same
dovecot package on FreeBSD is used for both installations.
My problem is now, that I use a rather complex sieve script to
automatically sort mailinglist based emails automatically into subfolders.
But as this script is using a dot it is now not moving the email into a
nested directory like:
github/haproxy/haproxy
but is generating a flat directory (depth 1) as
github.haproxy.haproxy
I cannot change the behavior of dovecot, as I have several users running
there and I do not want to cause problem for them changing the dovecot
configuration.
So I must modify the sieve script.
As I do not really know the sieve syntax, I would like to ask if
hopefully someone here can help me.
I think is is necessary to change the dots to slashes before the
fileinto is executed.
The sievescript I use to sort mailing based emails into subfolder is:
#
# 2016-5-2 Script to sort mailing list mails automatically to folders
#
##
require [ "regex", "include", "variables", "fileinto", "envelope",
"mailbox", "imap4flags", "vnd.dovecot.debug" ];
global ["sender_userpart", "sender_domain", "listname"];
# split out the various list forms
# Mailman & other lists using list-id
if exists "list-id" {
fileinto :create "${listname}";
stop;
}
# Listar and mailman like
elsif exists "x-list-id" {
debug_log "Mailinglist: x-list-id found";
if header :regex "x-list-id" "<([a-z_0-9-]+)." {
set :lower "listname" "${1}";
fileinto :create "${listname}";
} else {
keep;
}
stop;
}
# Ezmlm
elsif exists "mailing-list" {
debug_log "Mailinglist: mailing-list found";
if header :regex "mailing-list" "([a-z_0-9-]+)@" {

fileinto :create "${listname}";

}

elsif exists "x-mailing-list" {
debug_log "Mailinglist: x-mailing-list found";
if header :regex "x-mailing-list" "^s*([a-z_0-9-]+)@?" {
set :lower "listname" "${1}";
fileinto :create "${listname}";
} else {
keep;
}
stop;
}
# Smartlist
elsif exists "x-loop" {
debug_log "Mailinglist: x-loop found";
if header :regex "x-loop" "^s*(a-z_0-9-]+)@?" {
set :lower "listname" "${1}";
fileinto :create "${listname}";
} else {
keep;
}
stop;}
# poorly identified
elsif envelope :contains "from" "owner-" {
debug_log "Mailinglist: poorly identified matched";
if envelope :regex "from" "owner-([a-z_0-9-]+)-outgoing@" {
set :lower "listname" "${1}";
fileinto :create "${listname}";
} elsif envelope :regex "from" "owner-([a-z_0-9-]+)@" {
set :lower "listname" "${1}";
fileinto :create "${listname}";
} elsif header :regex "Sender" "owner-([a-z_0-9-]+)@" {
set :lower "listname" "${1}";
fileinto :create "${listname}";
} else {
keep;
}
stop;}
# other poorly identified
elsif envelope :contains "from" "-request" {
if envelope :regex "from" "([a-z_0-9-]+)-request@" {

maybe use:

and check what happens?
