I run my own business and send invoices through email with the program NCH Express Invoices. Since I have got the new att uverse router I can not send or receive. My software prompts I open ports...forwarding from public port 96 to 127.0.0.1 port 96. Also the new system will not allow me to send emails from my email client on the same server... but it allows emails to be sent from a different email address on that same server. Can you make any sense of this? I already checked all my software settings and that is not the issue. I believe it may be on at&t's end. Please help!
