The two signposts your code will use to determine what user is responsible for text in the mailbox file are the lines that start with "From " and "From:". (Remember that these are only significant when they are the first thing in the line.

These represent the end and the beginning of an area of responsibility respectively: a user is responsible for the contents of a message after the "From:" header containing their name, but a "From " indicates the beginning of a new message they arent responsible for.
