mbg is an mbox forensics tool written for fun. It reads an email mbox file and constructs a multigraph of co-appearing email addresses and then writes out either a simple graph in DOT format or a time-dynamic multigraph in GEXF format.
The resulting graph file can be used to perform graph visualisation with tools such as Gephi.
The mbg program extracts a contact graph from an mbox file, constructing
edges between addresses that appear together in From:, To:, Cc: and Bcc:
lists.
