It is a lot easier using a web based e-mail, such as gmail or hotmail, etc.

Some providers do provide a web interfase for you account. You can find out about this by looking at their web site. I know that Comcast has this feature.

On the plus side, you can access your e-mail from any computer. Just remember to logoff, so nobody can use the back button to get to your account.

Normally when travelling there should be no problem receiving your emails, but sending requires a contact to your provider's SMTP server, and that is usually not allowed.
