Hello Viktor,
First of all, thank you for your answers and your patience with me.
Yes, you are right - in $mydestination is, as described in the
documentation, $myorigin = tachtler.net - NOT - included and
$virtual_mailbox_domains = tachtler.net (only).
https://www.postfix.org/VIRTUAL_README.html#virtual_mailbox
-> NEVER list a virtual MAILBOX domain name as a mydestination domain!
-> NEVER list a virtual MAILBOX domain name as a virtual ALIAS domain!
In /etc/aliases is defined
# Person who should get root's mail. Don't receive mail as root!
# Tachtler
# default: #root: you
root: kl...@tachtler.net
but this is ignored?
So, if I understand this correctly, /etc/aliases is not used because I
transfer the e-mail via lmtp(8) to dovecot and therefore local(8) is not
used?
Thanks for the explanations for my better understanding.
Best regards
Klaus.

See ADDRESS_CLASS_README. The aliases(5) map is used as part of
local(8) delivery. If "root@$myorigin", after any rewrites, resolves to
a local(8) transport (usually there's only one, the "local/unix" entry
in master.cf), then $alias_maps will be used as part of delivery, as
documented.

Well, is "$myorigin" listed in $mydestination, or is it in some other
address class? What is "root@$myorigin" rewritten to?
In this example, all lmdb are empty (but prepared), but converted to
lmdb format with postmap - but there is no evaluation of /etc/aliases.

This seems to suggest that "$myorigin" might be set to
"postfix.idmz.tachler.net"...
What are the domains that match $virtual_mailbox_domains?

On the other hand the recipient is "r...@tachler.net" and was not
subject to non-trivial rewrites, so perhaps $myorigin is "tachler.net"?
Delivery appears to be via "virtual_transport", or in any case via
lmtp(8), rather than local(8). Naturally aliases(5) don't come into
play in that case.
