Nach Update auf 4.2: Kopano nimmt keine Mails von extern mehr an

Ich habe gestern auf 4.2-3 aktualiesiert. Nach den ersten Hürden, die ich beseitigen konnten, bleibt jetzt noch das Problem, dass die Mails, die ich von extern abhole, nicht mehr ankommen in Kopano.

Hier die kopano/server.log:

Als Grund für die “Ablehnung” wird genannt: “dsn=5.4.6, status=bounced (mail for xxxxxxx.lan loops back to myself)”. Was muss ich dazu noch einstellen, damit es wieder funktioniert?

Nur zur Sicherheit (wegen der Meldungen im server.log) - der slapd laeuft
und univention-ldapsearch funktioniert?

Ja - wenn ich

univention-ldapsearch -LLL '(|(mailPrimaryAddress=*)(mailAlternativeAddress=*))' uid mailPrimaryAddress mailAlternativeAddress

aufrufe, werden alle Benutzer angezeigt mit ihren Adressen

Im Gegensatz zu der Aussage im Link https://help.univention.com/t/tutorial-fehlermeldungen-setting-up-univention-to-allow-multiple-e-mail-addresses-per-user/5590/10 das man

univention-config-registry set mail/postfix/virtual/enabled = 'false'

setzen muss, habe ich diesen Wert jetzt auf “true” gesetzt - seit dem funktionier mein Maileingang auch wieder wie vorher
