I would try a regular expression search and replace.

1. Open the search dialog
2. Search for the following:

^error sending to (\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b).*

3. Set the replace to:

$1

4. Make sure that "Regular Expression" is checked
5. Replace all, which should result in a file with a email address on each line.

I got that email regex from: <http://www.regular-expressions.info/>
which is also a great site to learn from.
