I've had reports from several sites where this fix
didn't have the expected result: sendmail kept dumping
core when using the frozen config file. I've now been
able to reproduce that on a SUN here. The difference
with all other SUNs here is that this one doesn't use
yellow pages, which makes a difference for getpwuid()
used in the setdefuser() routine.
I haven't tracked down yet where the problem now really
stems from, but a hack that has made it work on all
systems here is to just delete the setdefuser() call
completely (from setdefaults() where it was originally
and the first one in readcf() as per the fix I gave).
