problems with -expiredate on 620 archives

[Mattis Oliver <oliver.mattis@siemens.com>]

hello everybody,

i think i have a newbee prob.

how can i use the -expiredate on all my archives ?
my first try on an explicit directory delets all mails that match by the expiredate but generates 5 new mails.

i used this:
mhonarc -expiredate "01 Jan 2002" -outdir /lvol2/mhonarc/ietf-aaa/2000-07 *

how can mhonarc walk thru all my archives and delete the exired directorys too ?
my other try´s like this, doesn´t work:
mhonarc -expiredate "01 Jan 2002" -outdir /lvol2/mhonarc *

thanks for your support

oli
