I've never understood how spam filters operate.   As an end-user, it 
does seem to me that email has been getting less reliable over the decades.

I've digitally signed this message.  Perhaps that helps get through the 
filters?  Can nnagain@lists.bufferbloat.net sign its messages? I realize 
email signing is likely imperfect for hardcore security needs.  Why 
don't more people sign their email?
