findall expects a string as the target, not a list of strings.  you can either
use a loop to apply the RE to each string fragment separately, or join the
fragments into a single string before you pass it to re.findall.

on the other hand, your data looks pretty regular.  why not just loop over
the fragments and look for things that start with "From:" ?
