.mail is a generic top-level domain proposed by The Spamhaus Project in 2004, but unapproved by ICANN. Its purpose is to enable responsible message recipients to reliably and efficiently identify and accept spam-free mailstreams.
.mail would attempt to reduce the spam problem by maintaining a list of domains authenticated as both not belonging to known spammers, and providing verified contact information. The sTLD would contain the actual hostnames of servers used to send mail. A .mail domain would only be able to be registered by a party that already owns a domain in another TLD which has been in operation for at least six months, and whose WHOIS information has been verified for accuracy. The structure of the .mail domain consists of existing domain names with the new TLD appended, such as example.net.mail, associated with example.net. Unlike other domains, the .mail domain would not be fully under the control of the registrant, but would go to a publicly accessible server where the status and contact information of the domain could be seen, and complaints to abuse@server1.example.net.mail would go to an organization which monitors spam complaints and revokes names registered to spammers. Mail filtering software can also query the .mail address associated with a message and reject the message if the address is forged or revoked.
The mail or post is a system for physically transporting documents and other small packages, as well as a term for the postcards, letters, and parcels themselves. A postal service can be private or public, though many governments place restrictions on private systems. Since the mid-19th century national postal systems have generally been established as government monopolies with a fee on the article prepaid. Proof of payment is often in the form of adhesive postage stamps, but postage meters are also used for bulk mailing. Modern private postal systems are typically distinguished from national postal agencies by the names "courier" or "delivery service".
Postal authorities often have functions other than transporting letters. In some countries, a postal, telegraph and telephone (PTT) service oversees the postal system, as well as hasa authority over telephone and telegraph systems. Some countries' postal systems allow for savings accounts and handle applications for passports. The Universal Postal Union (UPU), established in 1874, includes 192 member countries and sets the rules for international mail exchanges.
