Anyone running outdated versions of sendmail has not only not met their
obligations as a sysadmin, but they are also asking to have their networks
owned.  Sendmail is updated so often because it has MAJOR security holes
and bugfixes.  I guarantee you that if you gave me one of the sites that
is running outdated sendmail, they could be "owned" in a very short time.
There are far too many remote sendmail exploits for older versions to not
upgrade.  Checking and doing a search on
sendmail will verify this.  So, upgrading should be a prioity to anyone
who's running anything less than Sendmail 8.8.8.
