Behind Microsoft Outlook, Mozilla Thunderbird belongs to the most commonly used email programs in the world. In addition to the mail functionality, also a news reader is included in the program. The software is available for all major operating systems and can be adapted by a variety of available add-ons and themes to your custom needs.

A special feature of the mail program is a self learning spam filter that becomes better and better with increasing use. Several user accounts that can contain multiple e-mail accounts (POP3 and IMAP) can be created in the program. This allows to use the program with more than one person and every person can manage all of their e-mail adresses simultaneously.

Of course, the program also supports encryption and electronic signatures. You can write and receive HTML emails. When receiving HTML emails, it is your choice whether you want to display the full HTML mail, only the text of the mail or only the harmless HTML elements. Special searches can be saved as so-called virtual folders. This can be used to access emails with certain criteria quickly.

Import from other mail programs

Integrated features allow the import of messages from the other mail programs Outlook, Outlook Express, Eudora and Netscape Communicator. Programs such as Windows Live Mail are not supported.

Calendar Extension

Lightning is an extension for Thunderbird, with which you can integrate a complete calendar into the e-mail application. With Lightning, you can user Thunderbird in the same way as Microsoft Outlook with its calendar function.
