From GDT SA:
e-MAN is both a contact management and a connections finder tool; It presents all the contacts existing in your mailbox and most importantly, it provides all the relationships among them. It is unique, because it allows you to find links with colleagues, business partners, clients and friends without subscribing to any site, both you and your contacts. It works autonomously. e-MAN does not stop there. It utilizes a mechanism that builds a private, encrypted database which can be exchanged among e-MAN users in order to expand contacts and relationships. Process and share your personal e-MAN databases with partners and friends and build a wide network of contact points along with their relationships.
