Oops. I looked at the original way too quickly. Thanks, Mark, for 
correcting my post. The lesson in this is that SMTP, like almost all 
computer command sets, is very intolerant of even the slightest mistake. 
It does exactly what you tell it to do and has no idea what you meant when 
you get it wrong. Using Telnet to test SMTP has its uses (I do it to make 
sure the anti-spam controls on the commands works since that's hard to do 
by other means) but unless you are prepared to type everything in painful 
detail, expect weird results. Mailman is best tested with real messages 
sent by a proper MUA.
