Does your ISP block port 25?
Fuckin Cox High Speed Access
Q: Why didn?t Cox notify customers that it would begin blocking all network traffic from residential customer IP addresses going outbound on port 25 (SMTP) at Cox?s routers (unless it is being sent to a Cox HSI SMTP server)?
A: Port 25 is on Cox?s blocked list as noted in the Subscriber Agreement and in information found on our support site. This information is available to customers at all times, and customers are instructed to routinely check the Policy for information on acceptable uses of the service and network. The current blocking of Port 25 does not reflect a change in our policy, but rather an enforcement of said policy for the benefit of all Cox High Speed Internet customers. This effort is mean to reduce unsolicited bulk e-mail sent on our Cox High Speed Internet network.
