DO uses third-party services to send emails. If you want to block only
their cloud ranges, blocking all of their announcements is appropriate.

Hello,
if we are talking about a list of DO IP prefixes, why not rely on
routing information with bgpq4 [1] instead?
I live in hope, that these published IPs are including cloud infra
only,
not other IPs, as eg. their official MTAs (outbound) etc, while that AS
ranges includes it.
I tried bgpq4 some time ago, while i do not remember which cloud
provider it was, and there was huge difference between published
IP range and whole ASN ranges.
regards
