Comment 41 for bug 490935

The accounts staff at the company I work for has flat-out refused to switch
from Outlook until this feature is implemented.

Ways that staff here use it that I'm aware of -
- For faxes, the incoming fax server sends them a fax as "Fax of X pages from
NNNNNNN". They change it to indicate the actual sender.
- Recruitment consultants use it to give basic details on candidates applying
for a position, since the job boards give a generic description ("Application
for job TN/307"). They might change it to "Bob Smith for IBM Position **Hot
Candidate".
- Fixing spam tagging in headers, as others have said.
