Could you build this?
Partial A basic UI for viewing emails is easy, but building a production-grade full IMAP/MIME parsing client with sub-15ms offline search across 50,000 raw .eml files requires advanced low-level indexing.
What it would actually take: A real client requires robust IMAP/JMAP state synchronization, full RFC 5322 MIME parsing (handling decades of edge cases and malformed headers), and an embedded full-text search engine (like SQLite FTS5 or Tantivy in Rust/C++) optimized for disk I/O and instant search latency. Developing a stable offline email engine requires deep systems programming and email protocol domain knowledge.
