.mail was a potential generic top-level domain originally proposed by The Spamhaus Project in 2004, but rejected by ICANN. Its purpose was to enable responsible message recipients to reliably and efficiently identify and accept spam-free mailstreams. The ICANN Board issued a resolution on 4 February 2018 to cease the processing of all applications for the .corp, .home, and .mail gTLDs.

== Proposed core functionality == .mail was an 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 domain was intended to be a publicly curated resources that could be updated as needed by the Internet.
