Better e-mail address analysis needed
E-mail address handles are not analyzed correctly, as opposed to complete e-mail addresses. For example a handle like this is in a To, From or CC line: last, first (DFG). The parenthetical acronym represents the division of an organization. The handle could as easily be "first last (DFG)". Also, consider that a To or CC line may contain mixed kinds of e-mail addresses or handles, some of which may have names embedded in ' ' or " ".
I also note that names tend to get scrambled in the analysis, with the first name of one person mixed with the last name of another.
