Most web hosting customers are simple SMBs - think restaurants, small
shops, a car garage, etc. They have no idea what DKIM is, never mind having
access to a DKIM signing server. The hosting provider has to hook up
everything for them and presumably, with enough encouragement, we could
eventually get hosting companies to implement DKIM signing for their
customers. That is not the case today.

Some transactional email providers provide a DKIM signing service with
CNAME-based DKIM key hosting. That's a great concept and we may one day
provide it with an API hook allowing the hosting providers to hook this up
for their clients at scale.
