Mailzustellung Postfix zu Kopano / Delivering mail from postfix zu kopano

english version below
Hallo,
leider empfängt mein Kopano keine eMails, obwohl Postfix diese beim externen Provider abruft.
UCS-Serverdomäne: verein.local
eMail-Adressen: @verein.de

Ich habe also in den Benutzereinstellungen den externen Mailabruf eingestellt und dem Benutzer die Mailadresse @verein.de als primäre Adresse eingetragen. Postfix funktioniert auch, wenn ich mir die mail.log anschaue. Aber irgendwie klappt die Verbindung zu Kopano nicht.
Was habe ich falsch gemacht?

Hello,
my Kopano doesn’t receive emails, although postfix is collecting them.
UCS-Domain: verein.local
mail adresses: @verein.de

So i enabled the reception of mails from an external provider and put the correct external mail address as the users primary address. Postfix is working, as i see it in the mail.log. But somehow the connection between Postfix an Kopano is not working.
What did i wrong?

regards
Ally

maybe this from the mail.err could be useful:

Can you post what is logged in the mail.log at delivery time? The logs from your first reply are not really related.

sure, mail.log:

funny, just were at the neighbours house for dinner. Came back and see alle the mails in Kopano. I didn’t do anything for this. Strange…

is there any reason to be worried about that LDAP error?

This has been discussed multiple times on this forum already. At some point the connection is closed by the ldap because of running into a timeout. kopano-server will in that case simply reconnect (which is what the message says).

That logging sadly also does not include any mail delivery.
