Confidentiality management of e-mail users in redistributed e-mail messages

A computer-implemented method, performed within and by a second client computer system, comprising:

• receiving, from a first client computer system, an e-mail message transmitted to a plurality of e-mail users having corresponding e-mail addresses;
• determining, by a confidentiality processor coupled to an e-mail messaging client within the second client computer system, whether or not to cause display of an email address associated with a particular one of the plurality of e-mail users;
• and
• displaying, by the e-mail messaging client of the second client computer system, content of the e-mail message without displaying, based upon the determining, the e-mail address associated with the particular one of the plurality of e-mail users, wherein
• the first client computer system is configured to:
• identify a privacy preference, in association with the e-mail message, for the particular one of the e-mail users,
• modify the e-mail message, prior to sending, based upon the privacy preference, and
• send, to the plurality of e-mail users, the modified e-mail message, which is received during the receiving.

A second client computer system, comprising:

• a hardware processor configured to initiate the following executable actions:
• receiving, from a first client computer system, an e-mail message transmitted to a plurality of e-mail users having corresponding e-mail addresses;
• determining, by a confidentiality processor coupled to an e-mail messaging client within the second client computer system, whether or not to cause display of an email address associated with a particular one of the plurality of e-mail users;
• and
• displaying, by the e-mail messaging client of the second client computer system, content of the e-mail message without displaying, based upon the determining, the e-mail address associated with the particular one of the plurality of e-mail users, wherein the first client computer system is configured to:
• identify a privacy preference, in association with the e-mail message, for the particular one of the e-mail users,
• modify the e-mail message, prior to sending, based upon the privacy preference, and
• send, to the plurality of e-mail users, the modified e-mail message, which is received during the receiving.

A computer program product, comprising:

• a hardware storage device having stored therein computer readable program code,
• the computer readable program code, which when executed by a second client computer system, causes the second client computer system to perform:
• receiving, from a first client computer system, an e-mail message transmitted to a plurality of e-mail users having corresponding e-mail addresses;
• determining, by a confidentiality processor coupled to an e-mail messaging client within the second client computer system, whether or not to cause display of an email address associated with a particular one of the plurality of e-mail users;
• and
• displaying, by the e-mail messaging client of the second client computer system, content of the e-mail message without displaying, based upon the determining, the e-mail address associated with the particular one of the plurality of e-mail users, wherein the first client computer system is configured to:
• identify a privacy preference, in association with the e-mail message, for the particular one of the e-mail users,
• modify the e-mail message, prior to sending, based upon the privacy preference, and
• send, to the plurality of e-mail users, the modified e-mail message, which is received during the receiving.
