Netlink does not directly support webmail because it is not possible to secure this type of access to the email server howerver here are some sites (totally unrelated to Netlink) that allow you to get your netlink email via a browser
http://www.mailstart.com (read the restrictions)
http://www.e-mailanywhere.com/
if you know of others, please email us and let us know so we can put links here.
