a brief update to the situation-
I went ahead and found the nms formmail script and uploaded it to the server, since that is *apparently* the script that the server recognizes, not the MSA version. I configured it, and now am receiving a new error message:
CGI Error
The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are:
Unrecognized character \320 at F:\domains\julie\cgi-bin\formmail.pl line 1.
I'm gonna keep plugging away; maybe this damn form will work someday.
