Bitcoin spam using UTF-8 mathematical monospace characters-- except
that the html tags have to be in the low ascii character range of
UTF-8.

Does outlook.com make any effort at all to filter outbound mail?  In
the past 6 hours we've had 768 of these from 256 different accounts. I
have had full raw message for only three in the past few days and I
have sent them to ab...@outlook.com.

FYI part of the sender list below. I don't perceive a pattern to how
they are generated. (This is from sort -u, not the order of arrival.)
