matches, they will be shown in a confirmation dialog and you can
1665
decide what to do with them. The default size for filtering is 50,000
1666
Bytes; this is a good value as the overhead is kept to a minimum --
1667
every message that is looked at by the filter causes additional
1668
traffic because the header of the message is downloaded twice. The

default action is <guilabel>Download mail</guilabel> to prevent the
