Nope, it's individual file removals.

The FS could delay expunging a mail on the server a little after getting the 
request to remove the respective file, so things could be batched. If the FS 
implements caching and an offline mode, it has to decouple local file from 
network operations anyway, and that should be rather simple to implement.

The more interesting question is whether the trash merging of local volumes and 
remote mails is really what one would expect. It essentially means, you can't 
make space on your local disk by emptying the trash without at the same time 
removing trashed mail from the server and vice versa (without going manually 
through the trash, that is). Seems not really related to me.

Moreover, if we ever switch to a modern file system like logfs or btrfs, the 
trash becomes superfluous anyway, since one could resurrect deleted files 
anyway, as long as the disk space hasn't already been claimed otherwise.
