I found this one too.  My first idea was to change the string to uppercase
assuming that sendmail mapped the string to lowercase before doing the
comparison.  Strangely enough that didn't work.

What did work was to put a space in the string.  Since the parser uses
spaces to delimit words, sendmail will never return a space inside the 
command word (I'm not positive on this point, but it seems to be the case).
Anyhow, I changed "debug" to "a bug".   :-)
