[sylpheed:31838] Filters in Sylpheed?

[Herbert Loose]

Hi,
I'm using sylpheed for many years in several linux-distros (now 2.2.7)
Very glad for that quick and easy program, thank you all!
My question: Is it possible to leave or/and delete unwanted mail on my
mail-server (gmx, pop3) without downloading it first?
It seems to work, but AFTER downloading the unwanted (and in filter
defined) mail (much time on my slow modem!)

Thanks again,

Herbert Loose
