This bug was fixed in version 8.9.0 of sendmail (released last week).  From
the RELEASE_NOTES file:

8.9.0/8.9.0     98/05/19
...
        Limit the size of the HELO/EHLO parameter to prevent spammers
                from hiding their connection information in Received:
                headers.

The current version is available at ftp://ftp.sendmail.org/pub/sendmail/.
