Why do I still receive spam from blocked Top Level Domains?

[Guest]

I've barred all but 5 international country codes (top level domains), but I
still receive junk email from them. Can it be stopped?

Also, domains registered in the USA notoriously omit their country code
(given in the list as "US"). If I bar the US TLD, will it stop me receiving
emails I might appreciate from people like Microsoft?

And why is the TLD for Gt Britain GB, when we use UK?

What you are asking about is the ccTLD (country-code top-level domain),
not the [generic] TLD, like .com, .org, and .net. Where do you think
the Internet started, huh? You think it was called World War One at the
time? They didn't call it WW1 until WW2 happened. Country-code
top-level domains (ccTLD) weren't needed until the Internet started
getting adopted in other countries. If you are too young to have lived
through the inception and development of what is not colloquially
referred to as the Internet, start doing some Google searchs on its
history; for example, http://en.wikipedia.org/wiki/ARPANET. The USA
didn't need the .us ccTLD because, one, they invented the Internet and,
two, ccTLDs didn't exist then. The ccTLDs correspond to a country,
territory, or other geographic location *outside* of the USA, but that
doesn't prevent anyone from using them once ccTLDs became defined.

ccTLDs started getting defined in 2000. You think the Internet existed
only since 2000? Have a read at http://www.icann.org/cctlds/.

And why is the TLD for Gt Britain GB, when we use UK?

Since when has the UK been solely composed of Great Britain? Read
http://en.wikipedia.org/wiki/United_Kingdom.

Go read http://www.iana.org/root-whois/index.html. Whether .gb or .uk
gets used depends on what the registrar for the TLD was assigned to
manage. UKERNA and Nominet are both located in Oxfordshire. Doesn't
take much Googling to find relevant articles, like
http://en.wikipedia.org/wiki/Country_code_top-level_domain which says,
"uk (United Kingdom): The ISO 3166-1 code for the United Kingdom is GB,
however the JANET network had already selected uk as a top-level
identifier for its pre-existing Name Registration Scheme, and this was
incorporated into the top-level domains. gb was assigned with the
intention of a transition, but this never occurred and the use of uk is
now entrenched." So there was what was supposed to get used (.gb) and
what got used before that adoption (.uk) and which mushroomed to
overwhelm the proposed ccTLD.

How do you "bar" spam from being received? Do you filter the 'From'
addresses? I have never seen a 'From' address in spam that isn't forged,
so filtering on that level doesn't make any sense to me.
