Bug: unreachable code

The following code is unreachable:
#

```
if (!list || list.length <= 1) { // ponymail.js L3998

// List may be private...who knows?
if ((list && list.length > 1) && (!login || !login.credentials)) {
popup("List not found!", "Looks like this list is either not here or private.
You can try Logging in to resolve the situation.", 60) // <= **unreachable**
}
else
```
#

It's not possible for list to be both false and true; nor is it possible for list.length to be <=1 and >1 so the popup can never be reached.

Start in ponymail.js around L3998 and inspect the surrounding list and login flow. Determine the intended behavior for the listed condition and review any nearby checks before changing it; done means the reported popup path is no longer unreachable without breaking the list-not-found or private-list behavior.
