Automatic deleting of old msgs in Mutt?

[Andras Simonyi <simka@ludens.elte.hu>]

Hello,

I'm struggling with the task of automatizing the deletion of too old
messages in this list ;-). (They are in a separete mbox) I had a working
script which could do this using the grepmail utility, but I'm curious
whether this can be done from within Mutt... I thought that with a
clever .muttrc it's possible and I experimented with the folder-hook
command but without much success (the goal would be that Mutt could
automatically delete messages older than 5 days when entering or leaving
the folder), because itt seems that after the folder-hook command only
setting of some variables is possible and not tagging etc.

TIA: Andras
