What it means is that you used mailq wrong. You don't need any
parameters but if you provide any, they are a list of message IDs.
Since no message ID will be your localusername it will fail. Try mailq

I don't have nslookup installed but it seems wierd to me that one
hostname would have more than one IP address.
See what mailq say and see what are in exim's logs.
