Without having a "real" bounce, it is really ;-) hard to tell anything definitive EXCEPT "mail is mail" -- LISTSERV(R) generates email, and email being what it is, sometimes produces anomalous results. LISTSERV is NOT unique in its generation of email e.g., if it is happening to LISTSERV-generated mail, no doubt it is happening elsewhere with person-to-person email. Many folks don't even know that they are having a problem, and claim that they are receiving all of their mail (I've always been amazed at how they know this); and in fact list-owners like you are the bearer of bad news, sometimes getting "shot" in the process. Here on LSTOWN-L, we all know the critical information infrastructure that email constructs. A breakdown in that system bears pursuit. Sometimes we are successful in communicating with a cognizant system/network administrator and feel fulfilled. Sometimes not.
