Ok, i checked first all curves i was suspecting with OpenSSL1.1.0
I had all that curves before with exim4.87 and
openssl1.0.2-with-chacha-patch
I checked all against my ecdsa-cert and was only able to negotiate
secp384r1 and not more.
With an extra RSA-Cert i was able to use prime256v1 as default setting.

Short Result:
RSA: secp521r1,secp384r1,prime256v1    works
ECDSA: secp384r1                         works


all other combinations failed.
So i am missing X25519,brainpoolP512r1,brainpoolP384r1

In the moment it feels like a downgrade to me.

In the Logs are all ECDSA-tests and one RSA-test which proves it works
with RSA in default setting.
Dovecot seems to have a similar problem now to support multiple curves
with OpenSSL1.1.0.
In version 2.2.26.0. The ECDSA-Cert runs only with secp384r1.
That works by default.
Found the following reason stated in dovecot-mailing list:
--------------------------------
OpenSSL >= 1.0.2 automatically handles ECDH temporary key parameter
selection.
For OpenSSL < 1.0.2 we must manually specify a named elliptic curve that
Dovecot will use to generate an ephemeral key pair. By default we try to use
the same named curve as that used in the server's private EC key file.
If this
attempt fails, a fall back curve of NIST P-384 (secp384r1) is used instead.

RFC 6460 states that NIST P-384 MUST be used for cipher suites that include
AES-256. For cipher suites that include AES-128, RFC 6460 states that NIST
P-256 MUST be used. No matter which curve is used as a fall back option,
Dovecot will be non-compliant. The reason for selecting NIST P-384 as a fall
back curve is to ensure that the non-compliance is in the form of providing
too great a level of security for AES-128 cipher suites rather than too
little
security for AES-256 cipher suites.
------------------------------

If the other curves are not becoming available for ECDSA in this release
you should handle it like dovecot, so that a negotiation is possible and
not failing like shown in my logs:
