Purpose Sets a bcc'd recipient's user name for a message on the FirstClass server. Multiple recipients are supported by treating this attribute as an array. Backwards compatibility to previous code is retained.         Note The BCC attribute supports FirstClass mail lists, but does not currently support the use of gateways. If the user name is invalid, the message will fail. This attribute must be set or the message will not be delivered. Syntax ServerFile.BCC [(RecipientNumber)] = "UserName" RecipientNumber Used for multiple recipients. UserName Any user or conference name with send privileges to the recipient. Example In the following example, (1) designates the zero-indexed number of the recipient.  No (x) means 0, as does (0). Sub Main() dim sf as ServerFile sf.OpenFile ("Mailbox | Item", fcReadWrite) sf.BCC = "Administrator" sf.BCC (1) = "Carl Linnaeus"
