Hey Robert,
thanks for your reply.

Looking at your dovecot -n, you're using two different files here:
ssl_cert =
Are you sure these two files match, and contain the right things in the right order?
Yes, unfortunately I'm sure that everything has the right order. As you can see in the trace, both certificates (mine and the intermediate) get transferred to the client on connection.
We use a single PEM file as input for both of these parameters, and that PEM file contains, in this order:
-----BEGIN RSA PRIVATE KEY----- ... -----BEGIN CERTIFICATE----- ... -----BEGIN CERTIFICATE-----
... where the first BEGIN CERTIFICATE is the specific hostname one, and the second BEGIN CERTIFICATE is the Let's Encrypt X3 intermediate certificate that ends with "DNFu0Qg==".
Tried that, but without success. But your usage doesn't seem right to me. The parameters are not called ssl_cert and ssl_key for nothing. ;-) Normally you don't want your private key to have any other permissions than 600.
You're also manually specifying these non-default parameters:
ssl_cipher_list = ... ssl_prefer_server_ciphers = yes ssl_protocols = !SSLv2 !SSLv3
For testing, I would simplify. Does it work without any of those three things set?
Tried this before. I set all SSL specific settings exactly like my friend where it works without a problem. But it doesn't work for me.
Thanks anyway for your effort! Bastian
