Since LISTSERV version 1.5n I have problems with the service area of my local lists. New subscribers get the message that they are outside the service area. We have addresses like [log in to unmask] where SARA is a sub- domain of domain NL. The lists should be restricted to this subdomain so I put SERVICE= LOCAL end LOCAL= SARA.NL in my listheaders. In the DOMAIN NAMES file there are entries for SARA.NL and .NL (.NL for the other sub- domains of .NL). I traced EXEC LSVBESTP: it does not see the SARA.NL entry in the DOMAIN NAMES file because it does not start with a '.'. I can see three possibilities: 1) I don't understand the service concept and do something completely wrong. 2) The address syntax [log in to unmask] (without a node!) is unusual. 3) There is a bug in LISTSERV Can anybody help me?
