you can't install it yet because dovecot-2.3.4-2.x86_64 is not shown, probably due to the priority protection plugin:

-> 226 packages excluded due to repository priority protections

Try disabling it, see:

https://serverfault.com/questions/312472/what-does-that-mean-packages-excluded-due-to-repository-priority-protections <https://serverfault.com/questions/312472/what-does-that-mean-packages-excluded-due-to-repository-priority-protections>

Afterwards you should see all dovecot packages and can install version 2.3.4 again

Best regards,
Gerald
