Cock.li vs Disroot Email

Cock.li is a public email host from Cock.li, founded in 2013, offering email accounts and webmail through the web, Android, and iOS. Its services are free, with the Free plan listed at free. Mail access includes IMAP and POP at mail.cock.li, while XMPP is listed at xmpp.cock.li. Registration does not require personally identifiable information. New accounts cannot send mail until the user completes a browser proof-of-work challenge that uses a few minutes of CPU time. Cock-mail is described as an open-source, client-side webmail client connecting directly to the IMAP server over websockets, but its 0.0.1 alpha release lacks major features including SMTP. The privacy policy says registration details, stored mail, XMPP data, and 48–72 hours of IMAP and SMTP logs may be retained. Email is automatically scanned for spam. Account information is encrypted server-side, but mail may travel without encryption when TLS is unavailable or not attempted.

Disroot Email provides free email accounts through webmail and desktop or mobile email clients. Its Roundcube webmail includes threaded messages, filters, folders, attachment previews, and MIME and HTML support. Mail clients can connect using IMAP over SSL, SMTP with STARTTLS, SMTPS with TLS, or POP over SSL; suggested options include Thunderbird, Evolution, KMail, ClawsMail, Mailpile, K-9 Mail, FairEmail, and iOS Mail. Connections to the mail server use SSL, while outgoing messages use TLS if the recipient’s server supports it. Messages remain unencrypted on Disroot’s servers unless users encrypt them themselves. Disroot says its data is stored on its own servers in a Netherlands data center. Email logs may include usernames, IP addresses, and sender and recipient addresses; they are retained for 48 hours and not backed up. The free email plan includes a 1 GB mailbox and 64 MB attachments. Plus addressing routes sub-addresses to the original mailbox. Users can link a custom domain for sending and receiving mail through a lifetime feature tied to a donation amount they choose. The service supports Android, iOS, Linux, macOS, web, Windows, and extensions.
