Is that a fresh install you are using it sounds like? We are running v1.1.1 and this was a manual upgrade from WSP v2.1.0.944. We had just added a new server/virtual server and thought it was related to that new server. But we just tested this with an existing server and when deleting a website the domain is also being deleted.
Now I did create the new domain and website, then deleted it and that is deleting the domain. I ran another test and tried to delete a website that had been there prior to migration and the domain stays. So I ran a 3rd option, created domain/website added a mail account. then deleted the website only then once I created a mail account does the domain not get deleted.
I’m using MS DNS,
Instant alias i can confirm is broken, it’s currently being checked out by Scott to be fixed.
this issue and IP switch we however can’t reproduce on our dev and live
It could be simpledns but it would be odd, as basically the deletion script doesn’t specify providers to be used, and doesn’t have anything there to delete a domain on a site deletion which makes your issue weird.
this has been resolved in the latest builds! – this issue was related to the domain pointers fix.
