[Users] Completely deleting emails

[Cliff Laine]

When I delete an email from inside CM, should I do something like shred
from the terminal, or use a software cleaner program like Bleachbit in
order to delete any local copies that may still remain after I ask CM to
"Empty Trash"? Or is the latter sufficient to get rid of it beyond
retrieval (from police, jealous girlfriends, and other irritants) ?

Thanks
