[Mailman-Users] DMARC and Bellsouth, etc.

[Mike Starr]

I can't answer your specific question but a number of years ago I 
created a Yahoo account which required the creation of a Yahoo email 
address. I have never used that email address nor have I divulged it to 
anyone. Oddly enough, thousands of spam email addresses land in that 
Yahoo email account. I can only assume that Yahoo routinely sells email 
addresses indiscriminately... not caring if they're delivering those 
email addresses to spammers. The only other alternative is that somehow 
Yahoo's security at the time was so lax that spammers were able to hack 
into their servers and grab millions of Yahoo email addresses.

Best Regards,

Mike
