Newsgroups= None | usenet_newsgroup1,usenet_newsgroup2...
This keyword is not available in LISTSERV Lite.
This keyword defines the RFC822 "Newsgroups:" header for a list.
This field may be required by certain news gatewaying software and should be defined only if the list is gatewayed to usenet and if the gatewaying software does require it.
The default is Newsgroups= None.
A typical setting for this keyword might be:
* Newsgroups= bit.listserv.lstown-l
