DKIM issues are usually down to

1. MS DNS is being used and the dkim record hasn't been split onto multiple lines

2. SM is hitting a DNS cache, we don't have dns caching enabled within SM itself but it still uses our own resolvers which cache records.

3. DKIM was setup in SM using an older key length e.g. 768 or 1024 when the minimum required is 2048. If this is the case you need to disable and regenerate DKIM on the domain.

Try removing v=DKIM1; from the start just have p=

Hi Chris !

1. We use google DNS as primary and OVH DNS as secondary

2. No cache activated

3. key length is 2018

I try your tips and remove the "v.DKIM1;"....
