We can send email to Verizon.net from our domain teamwd.com. We can receive email from verizon.net email account but we can not send email from teamwd.com on there SBS 2011 Excahnge server. The client did get a new IP address due to getting a faster dsl connection. Not sure why we can not send a email to verizon.net. I asked verizon to add a ptr record on the connection but it did not help. Any help would be much appreciated.
