Cock.li

What is Cock.li

Cock.li is a free email hosting service that has been operational since 2013, offering user accounts across roughly a dozen alternative domains including cock.li, airmail.cc, 420blaze.it, horsefucker.org, and others. The service explicitly markets itself as professional email with an irreverent tone, emphasizing open access to email without surveillance-state requirements. As of 2026-05-30, the site claims over one million users and is actively developing a new webmail client called "Cock-mail" after discontinuing its previous Roundcube instance in 2025.

How no-KYC is it?

Cock.li is among the most permissive email providers for anonymous registration. The service does not require any personally identifiable information-no photo ID, no phone number, no real name. The registration page asks only for a desired email address, password, and CAPTCHA completion. The privacy policy, last modified 2025-04-03, states: "Cock.li does not require personally identifiable information to register for the service." The operator explicitly recommends using Tor or a VPN and following basic OPSEC to avoid linking personal information to accounts. There are no password resets, meaning account recovery is impossible-an intentional friction that preserves anonymity.

Privacy & security

The privacy posture is transparent but not absolute. Cock.li discloses that it may retain registration details (email, hashed password, IP, user agent, timestamps), mail storage, filters, XMPP data, and 48-72 hours of IMAP/SMTP logs. HTTP access logs are also kept. The operator candidly states: "You can't" fully trust them-any email provider can read mail in plaintext before storage, and the service does not offer server-side encryption. Users are urged to use X.509 or GPG with correspondents and to download and delete mail regularly.

A significant incident occurred in June 2025 when a threat actor allegedly exploited a Roundcube zero-day (CVE-2025-49113) to breach the service. Cock.li denied finding "signs of intrusion or successful exploitation" but announced it would stop using Roundcube regardless. The service now directs users to desktop email clients while its custom webmail is in development. Third-party security scanners flag the domain with mixed signals: ScamAdviser rates it "likely safe" while Gridinsoft assigns a 35/100 trust score citing blacklist detections.

Payments, fees & limits

The core service is free. Cock.li operates on donations via two funds: TEAMSAFU (supporting the development team) and SERVICESAFU (operating expenses). Donations are accepted in Monero and Bitcoin. The Monero address is published on the donation page. There is no paid tier or premium feature set-every functionality is available without payment. New accounts face a proof-of-work challenge to unblock SMTP sending, requiring several minutes of CPU time to prevent spam abuse.

User experience & support

The interface is deliberately crude and functional. Webmail has been absent for extended periods; the current "Cock-mail" project represents an effort to rebuild this capability after abandoning Roundcube. Support is informal and community-oriented, with contact addresses for admin, support, development, and security listed on the contact page. The operator warns that "support may be provided by aliens, intoxicated aliens, or wild animals walking around on DDR mats." There is no ticket system or guaranteed response time. The service maintains a public update log, warrant canary, and transparency page.

Who it's for

Cock.li suits privacy-conscious users who prioritize anonymity over polish, and who can self-support their email workflow. It fits those comfortable with desktop clients, GPG encryption, and accepting provider trust as a limitation. The service is less appropriate for users needing reliable webmail, professional support, or guaranteed uptime. Alternatives like ProtonMail or Tutanota offer more infrastructure but require more identifying information; Cock.li occupies a niche for maximal registration anonymity with minimal service guarantees.
