server to interact to start the processing of message

octet range (hex 00-7F, or 7-bit ASCII) using SMTP
(RFC 1652).
Allow Binary MIME
Allows the Binary MIME extension, if the sender
and receiver support it. Binary MIME avoids the
overhead of base64 and quoted-printable encoding
of binary objects sent using the MIME message
format over SMTP (RFC 3030).
