Hi,
so here is somebody who complains that he cannot send around 
anonymous letters. 
Hey, you proper fellow, what are your obvious reasons to 'sanitize' 
your partner? MIght it be you have no business to send mail there in 
interactive mode by telnetting into their sendmail?

I would say that there is no real world interest sending around 
anonymous letters. Sendmail has some features that are intended for 
interactive debugging. Some of those had caused a lot of headaches 
in the past, e.g., running commands under sendmail's privileges (see 
Morrison's worm). This one here is obviously to shorten interactive 
logins to the sendmail port (telnet).

So, now explain please to the list your obvious reasons and why you 
need that feature so badly, and why you do not call up ANS or send 
them mail, since you have a mailer's address? How about sending it 
to root at the host you 'sanitized' away?

Your Internet contact will be informed and I will request 
information on your activities.
