Ever heard of TCP? Byte streams aren't going away.

It has been around for more than 5 years. It hasn't needed any syntax
extensions except to work around bugs in other software (space after
MAIL FROM, for example). If it turns out someday that I haven't planned
ahead far enough, I'll make whatever changes are necessary.

For comparison: In February 1999, when it became clear that the revised
USENET message header field format was going to allow unencoded UTF-8, I
explained to Eric Allman how to make sendmail 8-bit-clean. (USENET
messages are often forwarded through mail by 8-bit-clean gateways.) A
few days ago, he released another security-fix release of sendmail. It
still isn't 8-bit-clean.
