For sure, they are not in ANY recycled bin.
I've doublechecked, no, tripple checked :-)
Even the table 'del_status' is empty, dunno if it is related to the bin...
But I noticed that some of the records seem stuck in the table: 'dns_mx' ...
I administer a server with over 900 domains in the ISPConfig DNS-Manager, they are all company domain names and never got one problem with them
Me neither, been using ISPconfig over a year now and I still love it :-)
Problem just started when i tried to add the Google MX records :-)
