How to run the spam filter over old mails

[leonidasj]

Hello guys,

activating the spam filter for some mailboxes was easy, but i am having a problem: i'd like to run that filter through an entire mailbox (about 17.000 messages) but at the moment only new incoming mails are affected by the filter.

Can anyone tell me how to make the spam filter check my existing mails in the mailbox?

Thanks & Cheers
Leon
