Normally you would do this with an expire rule
pile 1 groups * days 90
However, there is a trick, if you are just carrying local groups then the pile
expiration rules are not very good at dealing with very tiny piles because
they work on full buckets and a full bucket is 10mb, so you need 30mb of
news before expiration will work exactly as expected.
The solution is to decrease bucket size if you only have local groups: e.g.
in dnews.conf
bucket_size 100000
>also just copy a group, how can I delete the over-time articles ?
tellnews delete_items group.name fromnnn tonnn
You have to know the item range you want to delete.
