Commercial email from the Verizon Online Marketing Team

[S Moonesamy]

Dear Verizon,

I received a commercial email from the Verizon Online Marketing 
Team.  The message is DKIM-signed by netsender1.com.  Is Verizon 
collecting email addresses from IETF mailing lists or IETF Contributions?

Regards,
