If you actually have examples of where base64 will bit us, you might

I'd be interested in hearing about actual problems with case
sensitive addresses seen now. I know that in the past, certain
IBM-based MTAs and MUAs had a tendency to upcase everything in sight,
but it's been many years since I've seen those in the wild.
Anyway, I've experimented with case sensitive addresses for the past
couple of years. I'm running a (small) TMDA-fronted mail forwarding
service (on gmane.org), and am using base64-encoded encrypted
addresses. And I haven't had a single complaint. But, like I said,
it doesn't handle all that many messages per day, so it would be nice
to get data from larger outfits.
(I just went through today's mail log, and I see that there actually
does seem to be a problem -- about half the addresses were invalid,
because they were downcased. And of those messages, 100% of them
were spam. So it looks like the address harvesting bots that
spammers use don't reliably preserve case.)
