This is a wish not a Bug.

I was looking for some server based options.

I like to leave the majority of my email on the server (POP3 server)

But when i get junk mail (or mail from certain high volume mail lists) I
would like my filters to be able to delete the appropriate messages off of
the server. I would also like an option to delete messages off of the
server after X number of days.

Also when I delete a message i would like it to be removed from the server.

thanks
