If you recall, questions about the return address cited in the subject of this message appeared on this list since 1.6 came into widespread use. I believe Eric mentioned that it was caused by an incompatibility between 1.5 and 1.6 (although I can't find his message in my archives). My question today is whether there is any likelihood that Turgut can fix the problem with some minimal change to LISTEARN (1.5). It doesn't look like the problem of mixed versions is going to go away any time soon. --Mark
