I've been adding some functionality to the master branch to deal with
this problem. In the future, it will be possible to stop caching *all*
headers, and just cache headers whose headername (Subject, To, CC, etc)
is already known in the dbmail_headername table.
Once that is in place you can start deleting rows from the
dbmail_headername table and not worry about values being re-inserted
when new messages come in.
