I haven't seen Microsoft IP block bounces on any of the lists I'm involved with in some time, but I used to have other issues with them. You need to go to <http://mail.live.com/mail/troubleshooting.aspx>. In the second paragraph under "Sender services, tools, and issue submission" you will see "click here to contact support" which goes to <http://go.microsoft.com/fwlink/?LinkID=614866>. Submit that form and be prepared for an iterative process in which you feel you are dealing with a robot, but you may ultimately get this fixed. Also, signing up for "Smart Network Data Services" <https://postmaster.live.com/snds> and maybe other things from <https://sendersupport.olc.protection.outlook.com/pm/services.aspx> can help you keep up with what they think of you. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
