First, I just discovered this list, and just subscribed in order to ask this question. If it has been addressed before, I apologise; someone can tell me where I can find the archived answer and I will go away. When I first subscribed to SAS-L (@VTVM2), the messages that arrived had my name and the others who subscribed at my institution, in the "To:" field, each on a separate line, i.e., To: "Robert M. Hamer" <BITNET%"HAMER@VCUVAX"> Another reader Yet another reader etc Then, perhaps a year or two ago, only my name started showing up; the other names disappeared. Then, about a month ago, the other names started showing up again, but this time, instead of each name on a separate line, they all appear on one line, which is more than 80 characters long, and therefor folds over on the terminal, and looks messy. I tried sent this question to one of the persons who are listed at VTVM2 as the "owners" of the list, [log in to unmask] No answer so far. Barry Grau of the University of Illinois hypothesized that it had something to do with upgrading to a new version of LISTSERV. I sent out the above question to SAS-L and got about 20 responses, most of which (it could be a biased sample) said, yes they had noticed the same pattern, and yes the current configuration was annoying and confused their mailers. So, anyone here know what is going on?
