Request unblock of TCP Port 25 Outbound

Hello,

 

We have a Business DSL w/Static IP block through AT&T.  I understand that AT&T blocks TCP Port 25 outbound by default (a very good practice), but I need this opened as we use this line for testing and monitoring which involves outbound SMTP traffic.

 

Can anyone point me in the right direction to have this resolved?

 

Thank you,

 

Erik

I am having this exact same issue. We have Business Fiber w/Static IPs through AT&T and need port 25 open for SMTP traffic.

Thank you in advance,

I am also having this issue.  I can't click on the provided link above because I get some sort of HTTP POST error.  Please let me know who I need to contact to request opening port 25.

 

Thanks!

You can only request to unblock TCP Port 25 if you are a business class customer. That being said, you would need to call UBIZ Care Support so that they can help you. The number I was given at the time was 877-503-2622 opt 4.

Hi,

I have similar problem.

Our company has moved to new location and subscribed to AT&T Business Fiber internet service with 32 static IP addresses about a week ago. Emails from our internal network can no longer be sent to customers.

Please unblock port 25 for SMTP outbound traffic.

Thanks,

Administrator
