2018 and we still have smtp over ipv6 blocked on all droplets. I’d love an update from the DO staff.

I would really appreciate an update from DO staff too on this issue. As @talideon pointed out, blocking the submission port 587 on ipv6 seems very odd.

We for instance use the google app smtp relay feature for all of our hosted servers to sent out notifications. We want to use ipv6 as much as we can but handicapping mail delivery feels weird.

Really ? Why not ?
