Anti-Spam Community Registry (founded by Spamhaus)
Intended use
To allow non-spam mail to be identified as such via an authenticatable address based on that of the mail server
Actual use
Not in use yet, as it is unapproved and not in root
Registration restrictions
Must already have a domain in another TLD for at least 6 months; subject to verification of WHOIS data; can be revoked if involved in spamming
Structure
Registrations must be based on existing domain owned by registrant, such as example.org.mail
Documents
Proposal to ICANN
Dispute policies
UDRP applies, but since registrations are based on other existing domain, ownership of .mail domain will follow original domain if it is transferred due to a dispute

.mail is a generic top-level domain proposed by Spamhaus, but unapproved by ICANN. It would attempt to reduce the spam problem by creating addresses which have been authenticated as not belonging to spammers, and with verified contact information, paralleling the actual addresses (in other TLDs) of servers used to send mail. A .mail domain would only be able to be registered by somebody who 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. If a particular mail server is at server1.example.net, the associated .mail address would be server1.example.net.mail. 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.

E-mail, or email, is short for "electronic mail" (as opposed to conventional mail, in this context also called snailmail) and refers to composing, sending, and receiving messages over electronic communication systems.
Thus, for example, the path...!bigsite!foovax!barbox!me directs people to route their mail to machine bigsite (presumably a well-known location accessible to everybody) and from there through the machine foovax to the account of user me on barbox.
Mails can be stored either on the client or on the server side.
