"   You can use the "@filename" directive in resend to move the
   command-line options of resend into a file readable only by the
   majordomo user/group. This will make it such that you can't find out
   the -outgoing address by connecting to your mailer and doing an EXPN
   or VRFY, or even locally by looking at the aliases file or NIS map."

What is the "@filename" directive"?
   
"   Another more direct approach is to simply disable EXPN or VRFY
   altogether. See the documentation for your mailer on how to do this."

Could someone be more specific about what needs to be done here?

Eric
