is rumored to have said:
Hi
Is there domain name discrimination in the email industry?
Absolutely. Domain names carry reputations. They make it easier to
discriminate between spam and ham. "Discrimination" is not a bad thing
per se.
For example, com, net, and org are considered to have higher
reputations, while info, xyz, and top are considered to have lower
ratings. The latter do attract a lot of spam because they are cheaper
in the first year. Will this lower the ratings of these domain names?
As many others have answered: of course.
There are often solid legitimate reasons for reputation. The stat that
matters is not how much of all spam comes from domains in a TLD, but
rather how much of the mail from those domains is spam. In SpamAssassin
we have 2 distinct TLD lists used for sender domains and for URIs in
mail. Those lists are based on what mail is seen by the systems that
share their masscheck results with us. If a TLD shows up in a
significant quantity of "ham" we will remove it from those lists.
The complaints I have seen about that from innocent parties who chose
their domains poorly usually focus on how their obscure little TLD
doesn't appear on the list of TLDs sourcing a lot of spam. That's an
irrelevancy, as no system is receiving all spam.
