Matt,

Is this specifically for SMTP?  I'm wondering about the gzip'd HTTP
option.  I'm not sure how widely deployed that option might be but
wonder if a similar option is available now that many (most?) SMTP
implementations are (supposedly) 8 bit clean.  Must admit I'm not sure
the UTF-8 emails I've received were not base64 encoded on the wire.

I guess this is a bunch of questions: Are you focused on SMTP?  Does
modern SMTP support a compression option that doesn't require base64
encoding?  Is that option widely available?

thanx,
     doug
