Use sensible domain name (the DNS one) when guessing ident information
Currently, the code would use getdomainname() call, which however returns something usually unset and not necessarily related at all to the DNS domain name (it seems to be mostly some scary NIS/YP thing). This patch changes the code to actually use the DNS domain name, which is also what tends to be used in emails, and we aim at emails with our ident code.
