Old sub domains

Just seeing is anyone knows how to fix this very minor thing. I noticed in my dreamhost panel > Mail > Webmail that there are about 8 old sub domains that are no longer in use or hosted with dreamhost. They are not in the Domains tab and I am wondering how to remove them from the webmail tab? If anyone knows I would appreciate the info.


If they’re anything like logfiles (in your home/Logs directory), they’ll never go away. But it’d be nice if you find a way.
