Supporting message sharing

A computer program product, comprising a computer readable hardware storage device having a computer readable program code stored therein, said program code containing instructions which, upon being executed by a processor of a mail hub device, implement a method for processing an email, said method comprising:

• transmitting, by the mail hub device to a Mail Thread Board (MTB) server, a request for a Mail Thread ID (MTID) and in response, said mail hub device receiving the MTID from the MTB server, said email having been received by a mail hub device from a first mail client, said mail hub device being a first computer, said first mail client being a second computer, said MTB server being a third computer;
• adding, by the mail hub device, the MTID to the email;
• transmitting, by the mail hub device to the MTB server, a request for additional data for the email and in response, said mail hub device receiving, from the MTB server, the additional data;
• adding, by the mail hub device, the additional data to the email to which the MTID was added, wherein the additional data includes a plurality of messages;
• transmitting, by the mail hub device to a second mail client, the email to which the MTID and the additional data was added, wherein the second mail client is a fourth computer;
• receiving, by the mail hub device from the second mail client, the MTID together with an indicated selection, by the second mail client, of a message selected from the plurality of messages;
• transmitting, by the mail hub device to the MTB server, a request, which includes the MTID and the selection of the message, to generate an update of the additional data, said update based on the selection of the message;
• receiving, by the mail hub device from the MTB server, the MTID together with the updated additional data based on the selection of the message, said updated additional data having been generated by the MTB server and stored on the MTB server;
• and
• transmitting, by the mail hub device to the first mail client, the MTID together with the updated additional data based on the selection of the message.

A computer system, comprising a mail hub device, said mail hub device comprising a processor, a memory coupled to the processor, and a computer readable storage device coupled to the processor, said storage device containing program code which, upon being executed by the processor via the memory, implement a method for processing an email, said method comprising:

• transmitting, by the mail hub device to a Mail Thread Board (MTB) server, a request for a Mail Thread ID (MTID) and in response, said mail hub device receiving the MTID from the MTB server, said email having been received by a mail hub device from a first mail client, said mail hub device being a first computer, said first mail client being a second computer, said MTB server being a third computer;
• adding, by the mail hub device, the MTID to the email;
• transmitting, by the mail hub device to the MTB server, a request for additional data for the email and in response, said mail hub device receiving, from the MTB server, the additional data;
• adding, by the mail hub device, the additional data to the email to which the MTID was added, wherein the additional data includes a plurality of messages;
• transmitting, by the mail hub device to a second mail client, the email to which the MTID and the additional data was added, wherein the second mail client is a fourth computer;
• receiving, by the mail hub device from the second mail client, the MTID together with an indicated selection, by the second mail client, of a message selected from the plurality of messages;
• transmitting, by the mail hub device to the MTB server, a request, which includes the MTID and the selection of the message, to generate an update of the additional data, said update based on the selection of the message;
• receiving, by the mail hub device from the MTB server, the MTID together with the updated additional data based on the selection of the message, said updated additional data having been generated by the MTB server and stored on the MTB server;
• and
• transmitting, by the mail hub device to the first mail client, the MTID together with the updated additional data based on the selection of the message.
