Is there a configuration change that needs to be made to change the alogorithm to sign the dkim certs, according to smartertools posts the certs are being signed with rsa-256 but if I test against gmail on dkvalidator the certs are all rsa-1. I have used 2048 bit certs. This is on a  7845 version, the weird part is my old v15 is using Rsa-256 to sign the certs fine.
