AT & T DSL Email Troubleshooting

 

If AT&T is your internet service provider, you many notice intermittent e-mail sending and receiving problems. This is an attempt by AT&T to control spam by blocking Port 25, which is the usual port for successful e-mail transfer between your computer and Stanton Street’s server. The bottom line is this blocked Port 25 makes it impossible to send email from Outlook on your computer.

Never fear! You can fix this. Before you pick up the phone to call us for help, please try the steps listed below to change blocked Port 25 to Port 366 or Port 465 in your Outlook settings.
