See graph . Your sample will vary. Most disappointing is Eudora, traditionally a great e-mail program, but even in ver. 5.0 its HTML support is not really adequate. Links not highlighted except when using an exclusive AOL method.
Links are hot, some headlines appear bigger than text.
Programs configured for the default Eudora HTML viewer do not support full HTML, do not control font size well, and do not allow submission of forms. The native Eudora HTML viewer is still limited. Cannot control fonts, colors. No color or hot links. Apparently does not support colored horizontal rules.
