4. A method for enhancing security of e-mails transmitted from a sender to a receiver over a data transmission network wherein a Message Transfer Agent (MTA) associated with said sender is in charge of transmitting an original e-mail sent by said sender, comprising:

dividing said original e-mail into a plurality of chunks using a predetermined algorithm, wherein dividing the original e-mail comprises division 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,

sending said chunks as e-mails over the data transmission network to a plurality of relay MTAs defined in a predetermined list of relay MTAs, wherein each of said plurality of chunks is sent 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 pathway of the data transmission network,

5. The method according to claim 4 , wherein each chunk is encrypted using a public key of said chunk assembly agent before being transmitted, each said encrypted chunk being decrypted when received by said chunk assembly agent using a private key.

6. The method according to claim 5 , wherein text of said original e-mail is encrypted by using the public key of said receiver before being divided into a plurality of chunks.

7. The method according to claim 4 , wherein the predetermined algorithm is “chunk #=1+<order number of the character>modulo x”.

8. A security system, comprising:

a Message Transfer Agent (MTA) operating on at least one computing device and associated with a sender for transmitting over a network an original e-mail sent by the sender, the MTA including a message splitting system operating on the at least one computing device for dividing the original e-mail into a plurality of chunks according to a predetermined algorithm and for forwarding the plurality of chunks to a plurality of relay MTAs defined in a predetermined list of relay MTAs, 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 a data transmission network, wherein the splitting system 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 the plurality of 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 the predetermined algorithm, the chunk number, and the chunk count in order to re-build the e-mail before sending it to a second mailbox corresponding to a receiver, wherein each of said plurality of chunks is transmitted through a different relay MTA of the plurality of relay MTAs 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.

9. The system according to claim 8 , wherein the message splitting system encrypts each of the plurality of chunks using a public key associated with the chunk assembly agent.
