No, but all otehr sendmail hoels are in place, including teh -d hole.

SunOS 4.1.x doesn't have the debug hole either.

The statement that ``AIX has had all standard Unix holes fixed''
surprised me greatly.  It had all the Unix bugs we know and love,
including rdist and sendmail.

And a number of other worse bugs as well.

And AIX was also hit by the ``this is a neat program but it doesn't
seem to work for normal users, let's ship it set-uid root'' craze
that seems to be going around like a wild fire among Unix vendors.

SunOS 4.1.3_U1 doesn't seem to be needing that many security patches,
at least not ones to plug *gaping* holes as AIX does.
