The problem is that you'll want to lock the file during the operation so
that new incoming mails won't get lost. But something like this (untested)
should work:

#!/bin/sh

lock_mailbox_somehow();
grepmail -d 'since 1 month ago' mailbox > tempmailbox;
mv tempmailbox > mailbox
unlock_mailbox_somehow();
