FromIDHeader decodes a Content-ID or Message-ID header value (RFC 2392) into a utf-8 string.
NewBase64Cleaner returns a Base64Cleaner object for the specified reader.
NewCharsetReader generates charset-conversion readers, converting from the provided charset into UTF-8.
NewQPCleaner returns a QPCleaner for the specified reader.
ToIDHeader encodes a Content-ID or Message-ID header value (RFC 2392) from a utf-8 string.
# Structs
Base64Cleaner improves the tolerance of in Go's built-in base64 decoder by stripping out characters that would cause decoding to fail.
QPCleaner scans quoted printable content for invalid characters and encodes them so that Go's quoted-printable decoder does not abort with an error.
