Addresses formatting

Fully Qualified Mailchain Addresses​

Mailchain addressing provides broad support for known address schemes, including Mailchain accounts and identities, blockchain protocol addresses, Web3 names, and traditional email. The format is based on the RFC5322 Addr-Spec Specification to ensure maximum compatibility with other programs and future-proof support for potential address schemes (‘local-part’@’domain-part’).
