mailrs-smtp-codec

v1.0.1 Experimental

Tokio Decoder/Encoder for the RFC 5321 SMTP wire format — switches between line-oriented command mode (CRLF-terminated, ≤1024 octets) and DATA mode (raw bytes until CRLF.CRLF terminator). Includes optional SMTP-smuggling protection: detects bare-LF before the dot-terminator and either rejects the payload (Strict) or normalizes line endings (Permissive).
