Ja, dovecot-lmtpd ist installiert.

liefert er im Log-File:

Wichtig ist nur die erste Zeile. Das mit nobody, systemd-timesync, systemd-
network da sucht er wegen der Replication irgendwie nach den drei Usern im /
var/vmail, die ja keine Postfächer haben. Aber er liefert nichts was auf lmtp 
hinweist. Ich finde nur noch das  von Gestern:

# journalctl -u dovecot | grep -i lmtp
