I looked further, and I don't think even that will help.  Because ....

Indeed.  It seems to log something whatever you do,
HELO+MAIL+RSET+QUIT logs , HELO+QUIT logs, HELO+VRFY+QUIT logs.  I
could not find any combination that does log something or other.

I did find a patch for sendmail to change this

http://www.helsinki.fi/~vmkari/smpatch.html

but applying that to my Ubuntu system is hard, bot not impossible, so
I might try.  Options are:

1) reduce the interval of the check from monit (not ideal)
2) don't check the connection on port 25 at al, just the process (not ideal)
3) ignore the syslog messages (annoys me)
4) reduce LogLevel is sendmail to 5 or lower (very bad idea)
5) Try to apply the minor patch and rebuild my own version of sendmail
(bit of work, likely not worth it as I'd need to try to keep up with
any updates UbuntuDebian push out)
6) Use syslog-ng or similar to drop these messages :-)
