I'm getting much less SPAM in the last year or so (yay!)
and I gather that's at least partly due to the shutdown of some
botnets. And I hate to say anything positive about ComCast but
I think another factor is that their filters are pretty good.
SPAM volume is now low enough that it's remarkable when one gets
through, so when one arrived this morning I had a look at the
headers and it reminded me of a question I've had for some time:
How does a message like this get delivered to me even
though the headers (at least those present in the
message as delivered) never mention my email address?
Last time I started to look into this (over a year ago) I think
I got as far as concluding that the trick somehow involved
the Blind-CC mechanism but then I got distracted by another
matter and didn't pursue it. Headers shown below, FWIW...
