in a little better detail, what are you trying to do.
You have to log into your isp to get on the internet.
If you want to send emails using another email provider, you may do so.
Example: I have Verizon as my isp. I don't use my Verizon.net email address at all or very rare occasions. I have a Gmail Account that I use to send all my emails.
Is that what you mean?
is there a free program that i can get that will block my isp when i am sending e-mails?
