The message says "probably" because LISTSERV has no way to know for sure.
It sent a file to RSCS, and RSCS sent it back - presumably because the
destination node is unknown, perhaps because the tag had incorrect syntax
or because the moon was in the wrong phase. You should have a look at the
files; if the VIA list contains TEMPLEVM, they were indeed meant to be
sent to wherever it is they are tagged for, so just transfer them to RSCS
and they will be processed. Otherwise you have to RECEIVE them and send
them back from a postmaster userid.
