There is a mail system said,
host east.xxx.com[3.138.xx.xx] said:
554 5.7.1 <adriel@myemail.click>: Sender address rejected: We
reject all
.click domains.
I am just not sure, does the .click domain have low reputation on
internet? so other providers choose to just reject it?
To a some extent, yes. It is probably far more common for mail systems
to use more nuanced tools like SpamAssassin that use scoring of many
attributes to make a spam/ham decision. In those cases, you won't get an
explicit statement like the above, but rather just rejection or
acceptance without details. SpamAssassin in particular does include
*.click in its lists of suspect domains for both transit systems and
payload URIs, based on the analyses done by our contributing systems of
actual email.
There's a reason for this sort of rejection. The people who have managed
the .click gTLD have done a terrible job of preventing abuses. The
overwhelming majority of mail claiming to be from a .click domain is
unsolicited garbage. For the systems I manage, it has been 100.000% over
the lifetime of the .click gTLD.
what's the high reputation domains then, .com/.net/.org?
There are no real "high" reputation gTLDs. A majority of email from any
gTLD is spam because about 90% of all email is spam (this varies widely
by target address.) You won't get any *affirmative* benefit from any
particular gTLD. However, you can be fairly sure that no system of any
significant scale will reject solely on the basis of having a
com/net/org/edu domain. Country code TLDs are also fairly safe, aside
from those which have been colonized into general availability (cc, co,
io, tk, etc.)
The "new" gTLDs with reputation problems all started their lives with
abuse-magnet policies (free trial periods for domains and/or promotional
pricing) and/or have chronically failed to police abusive registrants.
By not investing in trust and safety issues, the operators of those
gTLDs created their own bad situation: full of spammers and without good
tools for thwarting them.
