This may have been overlooked, but this is a
crucial feature when using mail in a collaborative environment. Not being able to see who was CC'd on an outgoing email is crippling.
I've dug through the code, looked at the DB schema (mail_contents), and the CC field value is not stored
anywhere in the table (meaning the mail file itself currently has to be parsed each time you want to get that info).
When doing a Reply To All, you've just got to hope for the best...

Is there ANY developer attention on this critical issue at the moment?
