Absolutely, forgive me for not putting it in before.
To modify the response given when you type "help" after establishing a
connection to sendmail:

smtp Commands:
smtp HELO EHLO MAIL RCPT DATA
smtp RSET NOOP QUIT HELP VRFY
smtp EXPN VERB
smtp For more info use "HELP <topic>".
smtp To report bugs in the implementation send email to
smtp support@fdt.net.
smtp For local information send email to Postmaster at you
To edit what sendmail reports upon a connection, edit your
/etc/sendmail.cf file:
# SMTP initial login message (old $e macro)
#O SmtpGreetingMessage=$j Sendmail $v/$Z; $b
O SmtpGreetingMessage=$j Mail Server.
Ready on $b.
Do not spam this site or use it as a relay without explicit
permission!
Again, edit this to your preference :) and restart your daemon.
This pretty much will give your sendmail version anonymity. It was useful
back in the "sendmail of the day" releases, however, now it's stabilized
somewhat. It's really nobody's business what version of sendmail
you run, so have fun!
