Abstract:
1. A system for enhancing security of e-mails transmitted from a sender to a receiver over a data transmission network, comprising: a Message Transfer Agent (MTA) operating on at least one computing device and associated with said sender for transmitting over said network an original e-mail sent by said sender according to a predetermined list of a plurality of relay MTAs; said MTA associated with said sender including a message splitting agent operating on the least one computing device and adapted to divide said original e-mail into a plurality of chunks according to a predetermined algorithm, wherein each of said plurality of chunks is forwarded to a different one of the plurality of relay MTAs on the predetermined list such that each of said plurality of chunks is transmitted over a different randomly selected pathway of the data transmission network, wherein message splitting means divides the plurality of chunks of the original e-mail at the character level, and wherein each of the plurality of chunks is preceded by a chunk number and a chunk count; and a chunk assembly agent operating on at least one computing device for receiving from said relay MTAs the plurality of chunks, said chunks received at a first mailbox corresponding to the chunk assembly agent, and for re-assembling the plurality of chunks using said predetermined algorithm, the chunk number, and the chunk count in order to re-build said e-mail before sending it to a second mailbox corresponding to said receiver, wherein each of said plurality of chunks is transmitted through a different relay MTA of the plurality of relay MTAs as a chunk e-mail, each chunk e-mail including a same mail header having a same destination e-mail address, the chunk number, and the chunk count, the destination e-mail address comprising an e-mail address of the chunk assembly agent.
