Is it possible to tell LISTSERV to ignore the case of node.domain.net.
 
Our Systems Director has pointed this out and says that there is no
gaurantee that a nameserver is going to return the node.domain.net in
the same case every time.  He says this is in compliance with and valid
according to RFC1035 Section 2.3.3 ?
 
If this is not possible can someone give me an answer to refute this?
 
Thanks,
