Hi all, It seems that we have somehow corrupted an entry in the database for dns. We have deleted a MX record and emptied the recycle bin. When we try and recreate the entry we kept on getting error messages that it already exists. I have looked at the pri. zone file and there is no entry in there. In addition it appears not to add the domain to the /etc/postfix/local-host-names file or the user to /etc/postfix/virtusertable file. We had a look at the database tables prefixed with dns_ but they are quite cryptic and doc_id appears to refer to different entity records in each table. Help please.
