says the domain IP address is listed on UCEPROTECTL3 which is described
as:

If you are on the UCEPROTECTL2/L3, you have an IP address from your ISP
that falls into a poor reputation range (i.e., the entire range of IP
addresses is blocked as a result of the provider hosting spammers).

Uceprotectl3 Reports Subnets
Subnet-based Blacklists are used to reject email from entire ranges of IP
Addresses, i.e. providers that are hosting companies sending spam, as well
as single IP Addresses that may fall in that range of IP Address.

Uceprotectl3 Reports Shared Hosts
Host-reputation Blacklists will list either single IP Addresses that host
multiple domains or entire ranges of IP Addresses from DNS &/or Email
Hosts that host email for their registered domains on shared email
servers. When one company sends Spam Mail or Unsolicited Bulk Email (UBE),
the entire ranges can be reported as blacklisted.

Uceprotectl3 Reports Sources Of Spam
Spam-based Blacklists are those that will list either single IP Addresses
or entire ranges that have actually received Spam, i.e. Unsolicited Bulk
Email (UBE) in their Spamtraps from an IP-Address. This could be a result
of a compromised email account, an Open Relay, or simply sending mass
emails / marketing and not following best practices according to the
"CAN-SPAM Act of 2003" (ref:
https://en.wikipedia.org/wiki/CAN-SPAM_Act_of_2003)

Uceprotectl3 Automatically Delists Entries
This blacklist does not offer any form of manual request to delist. Your
IP Address will either automatically expire from listing after a given
timeframe, or after time expires from the last receipt of spam into their
spamtraps from your IP Address.

Uceprotectl3 Accepts Payments Or Donations
This blacklist does support a manual request to remove, delist, or
expedite your IP Address from their database upon Payment or Donation of
fees to their organization. Please note the following; 1) MxToolBox does
not in any way advocate the paying of removal from any blacklists. 2)
Removal requests that are submitted without addressing the core problem
will likely result in your IP Address being relisted in the database which
can cause subsequent problems and extended listing periods without
release.

More information about UCEPROTECTL3 can be found at their website:
http://www.uceprotect.net

Reason for listing - Your ISP DIGITALOCEAN-ASN, US/AS14061 is
UCEPROTECT-Level3 listed because of a spamscore of 224.4. See:
http://www.uceprotect.net/rblcheck.php?ipr=138.68.194.30

So, it's a "bad neighborhood" or "guilt by association" issue that is
difficult to resolve.
