The full version of WebMail supports the following browsers:
Internet Explorer versions 6+
Firefox versions 1.5+
Safari versions 1.3+
For technical reasons, the full version of WebMail cannot be run in older versions of the listed browsers or in non-listed browsers, but it is possible to run the simplified version WebMail Mini (for more information, see chapter 2 WebMail Mini). WebMail Mini is run automatically in older versions of browsers, in text-based browsers such as Lynx or Links, in web browsers designed for mobile devices (this view type is described in chapter 3 WebMail on mobile devices). WebMail Mini does not require CSS and JavaScript.
To use the secured access to the WebMail interface (by HTTPS protocol), the browser must support SSL encryption. If it can be configured (e.g. in Internet Explorer), it is recommend to enable support for SSL 3.0 and TLS 1.0 versions.
