Shouldn't that be as long as nobody fetched the message instead?

That would of course be ideal, but that would make the feature useless.
I'm already getting multiple NNTP update requests per minute, so there
wouldn't really be enough time to react.

It seems like you're using serial numbers for the post IDs, so maybe it works to just track the highest (latest) fetched post and disable deletion for anything that's older.
Alternatively you'd have to mark the post with a boolean flag.

The internal ID also has the time encoded, so that can also be used for
this.
