  Configuring sendmail on Jaguar
Subject:   Privacy Options

My friendly neighborhood Solaris Sendmail admin at work noted that when one telnets to a sendmail server:


% telnet domain.com 25


you will get a reslt that looks kinda like this:


Trying X.X.X.X...
Connected to domain.com.
Escape character is '^]'.
220 domain.com ESMTP Sendmail 8.12.2/8.12.2; Sat, 11 Jan 2003 09:33:56 -0500 (EST)


which gives potentil hackers two clues: WHAT you are running and WHAT version. This (he said) is a *BAD* thing.


He suggested editing the sendmail.cf file and changing the privacy options to:


# privacy flags
#O PrivacyOptions=authwarnings
O PrivacyOptions=goaway,restrictmailq,restrictqrun


whichs sounds like a GOOD thing, however doing so and restarting sendmail (sudo kill -HUP [PID]) or even running the update scrip seems to have no effect.


Any suggestions?


thanks
