Hello Tobias,
Thanks for your reply.
I put your script into /usr/local/lib/dovecot/sieve/redirect.sieve
and compiled it with sievec.
I also put
> sieve_after = file:/usr/local/lib/dovecot/sieve/redirect.sieve
into my plugin section and enabled lmtp in both dovecot and smtpd.
Unfortunately this caused errors like:

a42fc59a8f9aa94a|inet4|mda|auth|be...@stuerz.xyz|be...@stuerz.xyz|be...@stuerz.xyz|1681074451|1681074451|0|1|pending|5|"mail.lmtp:
LMTP server error: 550 5.1.1 <vmail> User doesn't exist: vmail"
when sending a test email to myself.
I then removed "virtual <virtuals>" from my smtpd.conf and it replaced
"vmail" with "benni" (not be...@stuerz.xyz).
I have reverted the change in smtpd.conf again.

Heho,
The documentation for sieve is here:
https://doc.dovecot.org/configuration_manual/sieve/configuration/
Sieve is its own script language for mail filtering. Once you
configured it, you can either use pidgeonhole/managesieve to edit the
sieverc, or just write one to the right path on your server.
You are looking for a sieve script like this (does what you asked for
for my mail account for a couple of years now.):
"""
require ["variables", "envelope", "fileinto", "subaddress"];
if envelope :matches :detail "to" "*" {
set :lower "name" "${1}";
}
if string :is "${name}" "" {
fileinto "INBOX";
stop;
} else {
fileinto "delimiters.${name}";
stop;
}
"""
With best regards,
Tobias

Hello Michael,
Thanks for helping me!
I too use dovecot, but I'm not really familiar with it.
That's why I took most of my config from a tutorial.
As far as I can tell, I have to put something like this into my
config:
protocol lmtp {
mail_plugins = $mail_plugins sieve
}
But how do I connect it with my script?
I'm thinking of using a script like this:
#!/bin/sh
# Usage: $0 user[+tag]@domain.tld
# user[+tag]
user_tag=$(echo "$1" | cut -d@ -f1)
# domain.tld
domain=$(echo "$1" | cut -d@ -f2)
# user
user=$(echo "${user_tag}" | cut -d+ -f1)
# [tag]
tag=$(echo "${user_tag}" | cut -d+ -f2)
prefix="/var/vmail/${domain}/${user}"
[ "$tag" ] && echo "${prefix}/${tag}" || echo "${prefix}/Inbox"

Hello Benjamin,
what mda do you use? I use dovecot and a sieve script to process
incoming mail.
Instead of saving mail directly to maildir, I transfer it to the
mda via lmtp. The required changes on the smtpd site would look
like this:

I think this line has to be changed:

"/var/vmail/%{dest.domain:lowercase}/%{dest.user:lowercase|strip}
/Inbox" virtual <virtuals>
action "domain_mail" lmtp "/var/dovecot/lmtp" virtual <virtuals>
In dovecot, you need to activate&configure the sieve plugin and a
script for your user account.
