Bluemail requires JavaScript and works best with Internet Explorer (IE) 5.5sp2, IE 6, Netscape 4.7 or newer and Mozilla 1.2.1 or newer on windows. On Macs it works best with IE 5.1 or newer, Netscape 4.7 or newer and Mozilla 1.2.1 or newer. There may be issues connecting to Bluemail through other browsers, such as AOL’s proprietary browser, Opera, and older versions of Netscape and Internet Explorer.
