That error message format is typical for qmail (the smtp mailer program generating the error message). The author of qmail has (so far) refused to make his program generate error messages in any one of the standard formats. A few large sites which run LISTSERV with qmail have actually had to modify qmail so that it generates error messages that can be parsed by LISTSERV. Since you don't maintain the mail servers at Netzero, it is unlikely you'll convince them to change their mail server program. This is one of those annoyances that as a List Owner you simply have to put up with or don't allow anyone with netzero addresses to join your list(s).
