Just noticed something while looking at the data that is returned
from a Bergman "remailer-stats" email message:

Excerpt below:

As you can see there has been a sudden drop in "Mail" messages starting
on Sept 27th.

I think I understand why this has happened. But I have 2 questions.

What kind of messages are deemed to be "Mail"? Does this refer to
incoming mail?

Also, what kind of messages are deemed to "Intermediate"?

Thx.
Brian
