Re: [ietf-smtp] Draft for compressing SMTP streams

It is not quite that simple.

Most compression algorithms expect the input to be characters from some alphabet, such as 8-bit bytes. Base64 changes that, the bytes are not really visible. However, many of the input formats do not use bytes anyway, they are more properly seen as bit strings composed of variable length tokens. It does not really matter whether a compression algorithm sees six of eight bits from the middle of that string, when it cannot even tell where each token ends.

Au this point you can think of ways to turn six back to eight. But does it really matter to anyone?
