I wanted to convert Eudora email client files into MBOX file format. Then, so I searched on the internet and got SysTools MBOX Converter Software. This is one of the most robust tools for the conversion of MBOX files of email applications like Thunderbird, SeaMonkey, Apple Mail, Entourage, Eudora, Spicebird Mail, and so on. I would like to suggest this utility to other users as well. Because I am fully satisfied with this software's working performance.
