For example, the vast majority of email addresses on this mailing list are of the form: Bill Kelly <billk / cts.com> In some GUI environments it is harder to select the portion between the <>'s than to select the entire address. From RFC 1123: At every layer of the protocols, there is a general rule whose application can lead to enormous benefits in robustness and interoperability: "Be liberal in what you accept, and conservative in what you send" Gary Wright
