Ideally, you insert 'From address date` where address is the address without the <> from the Return-Path: and date is the string produced by the 'date' command. The attached addfrom script is what I use. It's overly complex for your purpose and converts one message in one file in place. You could probably adapt it to your purpose. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B. Dylan
