Could you build this?
No A from-scratch mail, calendar, contacts, and tasks suite requires interoperable implementations of IMAP, SMTP, CalDAV, CardDAV, and related security-sensitive protocols, which go far beyond what vibe coding reliably produces.
What it would actually take: A real version needs a Rust backend with protocol-compliant servers and clients (IMAP, SMTP with TLS and DKIM/SPF handling, CalDAV/CardDAV, iCalendar and vCard parsing), a sync and storage engine, and extensive interoperability testing against Gmail, Outlook, and other providers. It requires deep protocol and security expertise, plus large-scale testing effort to match existing clients.
