Thank you.  Just a bit mystified.  The email I sent to myself as a test is
not getting to me yet I am not receiving any error from an external account
I used to test with.

It means exactly what it says something connected to sendmail and did not
issue any commands that it would expect.

Someone may have been testing to see if sendmail was up and running or doing
a port/vulnerability scan to find your sendmail version.

This probably has nothing to do with mail not being delivered.

I have been watching my mail log with MailScanner and noticed the below
syntax and don't understand what it is saying.  Would anyone have a
suggestion?  I tried to send me an email and it has not been delivers.  My
gateway forwards the mail to an internal email exchange server.  The SPAM
gateway is running the latest SA and MS.
