DKIM signing certs with rsa-1 and not rsa-256
Question asked by Keith Dovale - 11/22/2021 at 10:56 AM

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.

I believe this may be a system-level (Windows) setting but I am not positive. I did a quick test from our latest public release and find SHA-256 being used to sign the messages.

v= Version:         1
a= Algorithm:       rsa-sha256
c= Method:          simple/simple
