I don't believe the "Sent" folder keeps track of any size.
I looked and don't see any "maildirsize" files in "Sent" folders.
So it doesn't look like it counts against either user or domain
quotas. You'll have to take a look at the spec to be sure.
I don't believe the Trash folder keeps track of size either.

It does, I'm sure. You may disable it (for example in sqwebmail and likely courier), but if you're a provider you're going to control all the space customers are wasting (specially if they are webmail users), including "Sent", "Trash" and additional folders.

In any case, you can use system quotas if you want to bypass
any/all of this to make sure everything is accounted for.

These problems must be highlighted much more, because people may think this "vpopmail domain quota" feature could solve all problems transparently, and this is not true.

I think this feature may be a first step, but must be followed by coherent changes in other packages, before it may be used in an integrated environment.
