Mine are below and they work just fine:

I notice all the ciphers use DH, so did you a generate a permanent DH key?
(https://wiki2.dovecot.org/Upgrading/2.3)
ssl-parameters.dat file is now obsolete. You should use ssl_dh
setting instead: ssl_dh=</etc/dovecot/dh.pem
You can convert an existing ssl-parameters.dat to dh.pem:
dd if=/var/lib/dovecot/ssl-parameters.dat bs=1 skip=88 | openssl dh
-inform der > /etc/dovecot/dh.pem
