Putting aside the mail reading bits, the regex for that would be: /START(.{140)/)/ with modifiers to fit your data format (which could have used a tighter description here). If you have several keywords, you might be better served by Parse::RecDescent.
Update: Having seen your data now, you might be better off splitting on whitespace. You may also be able to exploit the structure of five-character groups. The data you show doesn't seem to fit the description in the root node, am I missing something?
