Hello friends!

We make a handheld game system called Playdate, and our site lives at 
play.date. We find that our support email often doesn’t get delivered, making 
for occasionally very angry customers.

In debugging this, we’re looking at spam score.

In SA, .date is one of the “bad domains” that gets a heavily punished score 
(4.497) right out of the gate:

FROM_SUSPICIOUS_NTLD 0.499
FROM_SUSPICIOUS_NTLD_FP 1.999
PDS_OTHER_BAD_TLD 1.999

I found this bug on this topic:

https://bz.apache.org/SpamAssassin/show_bug.cgi?id=7915

And a poster says "Unfortunately, the science backs up that the TLDs are 
problematic.”

I was trying to research “the science” to understand it. The SA code references 
the following four sources:

# new TLDs used for spamming
# https://www.spamhaus.org/statistics/tlds/
# http://www.surbl.org/tld
# https://ntldstats.com/fraud
# https://dnslytics.com/tld

Looking at these:

1. Spamhaus says that .date is 3.1% bad. (.com is 1.3% bad.)
2. SURBL ranks .date at #187.
3. The nTLDStats page is just returning a 404, idk
4. DNSlytics just returns basic information about .date, like that it has 6,977 
domains

Can anyone help me understand “the science”? And how these domains are chosen 
for such a heavy punishment?

Is there any path to redemption, or is it that once they’re added, they're 
dinged forever?

Thanks for your help!

Best,
Cabel Sasser
