Is there a way to remove mail after 3-5 days on all accounts?

Biggest problem I have is I use the rob the bank feature...Well when you have 150 registered users my mail file has 8000 messages .

LoGD of course clears "read" mail after a set amount of days. Is there a way to clear ALL (unread and read) mail after a certain amount of days?

Im guessing they are marked as read, could take away the "read" checking..

Maybe Im wrong looking at it....In mail.php

Would I be correct in saying that deletes all mail read or unread after set days?

ALSO:
Big question I have is, since this is in the mail.php...What if this is a level 8 char that isnt going to expire and they don't login for 2 weeks. They aren't executing mail.php so, is the mail getting deleted?

ok cool

Thanks I just wasnt real sure about it and wanted to ask
