Overview

Cock.li is a free public email hosting service that has been operating since 2013. It offers professional-looking email addresses with a distinctive domain name, and its small volunteer team positions the service as a privacy-respecting alternative to mainstream providers. The service is accessible via IMAP, POP, SMTP, and a webmail interface called Cockmail, which is built on RoundCube and supports multiple languages including Japanese. It also provides XMPP instant messaging and can be reached through a Tor hidden service. Users can choose from 28 different domains, including cock.li itself. The service was initially run from the home of its German operator, but after the servers were used for bomb threats, German authorities seized the hardware. The operator subsequently relocated to Romania, and the service is now hosted on FlokiNET, a bulletproof hosting provider. Registration does not require personal information, and the use of Tor or VPNs is permitted. Cock.li does not scan email content for targeted advertising, and logs are retained for only two to three days. If law enforcement requests disclosure, the operator states that the correspondence will be made public. While the operator respects anonymity, he acknowledges that this cannot be technically proven, and therefore recommends the use of PGP (GPG) encryption. On April 28, 2021, operator Vincent Canfield announced that account registration had been closed after the number of registered accounts exceeded one million. Registration became invitation-only, and information such as IP addresses used to prevent and detect automated registration would no longer be recorded. The service continues to operate with a user base of over one million, sustained by cryptocurrency donations and volunteer work.

History

Cock.li was launched in 2013 as a free email service. Initially, it was operated from the home of its German operator. However, the service's servers were used to send bomb threats, leading German authorities to seize the hardware. As a result, the operator moved to Romania, and the service is now hosted on FlokiNET, a bulletproof hosting provider known for its tolerance of controversial content. The service has been mostly alive since 2013, according to its website, and has grown to over one million users. On April 28, 2021, operator Vincent Canfield announced that registration was closed after the user count exceeded one million. Registration became invitation-only, and the service stopped recording IP addresses and other information used to detect automated registrations. The service continues to operate, relying on cryptocurrency donations and volunteer work.
