autodelete messages at exit of mutt or startup of mutt?

[Raphael Brunner <lilo-@xxxxxx>]

Hello everybody

is there a possibility to autodelete old messages in maildir-boxes if I
exit mutt oder startup mutt? 

Now I have this settings in .muttrc :

folder-hook zz_mailinglist_mutt-users           'push D~r>32d!~F\n'             
# Delete all > 32 days

and a lot rules more for each mailinglist...
But I don't want to go in every mailbox to activate those rules...
Is there a simple solution known?

Thanks a lot for your help!
Greetings, Raphael
