Cypht
Every email account you own lands in one combined inbox with Cypht, putting Gmail, Outlook, a work Exchange server, and your RSS feeds behind a single login. Combined views do the heavy lifting: one inbox, one unread list, one sent folder, and one flagged list span every connected account, and each account still keeps its own folder tree when you need to work inside a single mailbox. Messages move freely once they are together: search across all accounts at once, then copy or move mail between accounts, flag favorites, and clear out large mailboxes from the same list. Sending identity stays organized through profiles, which pair an incoming account with an outgoing SMTP server and attach a signature and reply-to address, so the right name and footer go out with every message. New accounts connect over IMAP, JMAP, or Exchange Web Services, and provider auto-discovery fills in server settings for major services instead of making you look up ports. Everything is a module set, so LDAP authentication, folder sharing, and integrations like WordPress and GitHub can be switched on or left out entirely. Pages stay small and quick on modest connections, which suits the ISPs, schools, and small teams Cypht was built for. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. LGPL-2.1 licensed.
