concerns have been shown by customers over the bill's effects. On June 24, 2019, Fastmail launched refreshed look, with a new logo, app icon, colors, and website. The logo now reads "Fastmail" instead of "FastMail". Features Fastmail offers multiple domains (all but one of them starting with "Fastmail", and then different top-level domains) which users can choose from, while also allowing customers to use their own domain. Users are also able to create calendars and notes in the web mail environment and sync them over the IMAP and CalDav protocols. Technology The site developers are among active contributors to the widely used Cyrus IMAP open source software project and include the lead developer and maintainer of Perl module Mail::IMAPTalk. Fastmail supported the development of the free software webmail interface Roundcube and developed JMAP – a new open email protocol. Fastmail also provides for two-factor login using a YubiKey. While associating one or more YubiKeys with a Fastmail account will not prevent normal logins, it allowed for logging on to an email account with just a YubiKey and its auto-generated one-time passwords, making it suitable for accessing email on public machines. The YubiKey-only login feature was discontinued in July 2016, as it was rarely used, according to the Fastmail team. The email service also supports the U2F and the TOTP protocol as a secondary sign-in factor, allowing users to sign in with their password and a security token as an extra security feature.
