Current List of ISP's and their SMTP servers.

The SMTP server is a configuration setting within all pop E-mail applications. When using a pop E-mail application such as Eudora, Microsoft Outlook, Entourage, Mail, Netscape, Thunderbird etc. The SMTP server setting must be configured correctly or outgoing mail will not be sent. (Normally, checking mail will still work if the SMTP server is not configured correctly within your pop mail application).
