I see a lot of spam and viruses with the bare hostname, but haven't seen any 
with the @ sign.. maybe I'll have to look harder..

Well, first we need the legitimate server operators to get a clue.

Unfortunately, a quick glance at my own email finds several legitimate senders 
that are using bare hostnames.

Many I don't really care about normally, but I sometimes need email from them 
when using their tech support. (ie: APC)
