am not sure what you mean by "security reasons", please do clarify
You can always modify the content of the HELP file. Sendmail gets it 
from *|/etc/mail/helpfile. |*|That will obscure whatever it is you want 
hidden from other users using HELP.
||But seriously, you should consider alternatives like exim or 
postfix.Sendmail's security history isnt very great.
