We are using M1070 in our email infrastructure and would like to upgrade the certificate from SHA1 to SHA2. Could you please suggest on how can I proceed further?
To use a SHA-2 cert you would basically request a new certificate from the CA and request SHA-2. You could also create a signing request for a SHA-2 certificate on an external server and get it signed by the CA.
Signing requests for SHA-256 and other stronger certificates cannot be currently created on the ESA and is being tracked under the below feature request.
