Maxprog | eMail Verifier FAQ - E-mail server connection failure

The problem you are having is due to Port 25 blocking. This blocks any 3rd party outgoing mail servers from being accessed while connected to your ISP network via Dialup, DSL or Cable. Many ISP's (Internet Service Providers) are blocking what is called "Port 25" which is the port used to send e-mail. They have chosen to do this to cut down on the amount of "SPAM" mail that is sent. All e-mail sent via the Internet is routed through the port 25, the channel used for communication between a mail client and a mail server.

Unfortunately, there is nothing we can do to change this. The port #25 is the standard for sending messages and the one eMail Verifier uses.

The only solution is switching to another ISP. Smaller local ISP's usually do not block Port 25. Here are some web sites that can help you find thousands of ISPs:

You can check with your dial-up provider to see if they are doing this. Here are a few of the major ISP's that block Port 25:

• NetZero
• Mindspring
• MSN
• Earthlink (http://help.earthlink.net/port25/)
• Flashnet
• MediaOne
• AT&T
• Verizon
• Prodigy
• Bell Sympatico
