| Query all mail sent from a selected sender, based on all senders gathered in the current mail database (fig. 11) |
| sender is uniquely identified by his/her userid |
| a specified folder can be used to narrow the searching, as in many other query options |
| Note the sender list is not pre-entered or edited. It is automatically built when a new mail is being incorporated into the database from the MH mail folder by the parser --- another dynamic feature of web-db integration |
