Could you build this?

Partial The API, SMTP, and webhook layers are vibe-codeable, but reliable sending and receiving depends on deliverability, IP reputation, and DMARC handling that take years to get right.

What it would actually take: Build an MTA on top of Postfix or a Go/Rust SMTP stack with queues, bounce processing, and DKIM/SPF/DMARC handling. The hard part is deliverability: warming IPs, managing reputation with Gmail and Outlook, and running inbound mail at scale, which requires email-infrastructure operations expertise and ongoing ISP relationships.
