How can I forward mail without keeping local copy

[Mantis]

I am using hMailserver with Plesk 8.2.
Lots of my clients want to be able to put a forwarder on their mailbox and NOT keep a local copy so that the mailbox does not fill up.
hMailserver has this facility via the hmailserver admin tool, but Plesk doesn't seem to support it which seems a bit daft.
Does anyone know a work around etc?
Thanks

I cant as the mailbox tick box is greyed out in a ticked state.
