namecheap-client 0.1.1

//! Configure a domain's DNS host records for email (MX, SPF, DKIM, DMARC).
//!
//! `setHosts` replaces the entire set of host records, so this example sends
//! every record the domain should have, including the website records. Run it
//! against the sandbox first:
//!
//! ```sh
//! NAMECHEAP_API_USER=your-user \
//! NAMECHEAP_API_KEY=your-key \
//! NAMECHEAP_CLIENT_IP=your.whitelisted.ip \
//!   cargo run --example dns_email_setup
//! ```
