Yes, I do know about this. In fact, I get several hundred bounce messages
every time it happens. The bug is in Solaris and/or Solaris' sendmail
and/or the fact that our distribution machine is experiencing massive
hardware failures several times a day and Sun is dragging its feet in
response. *sigh*
I tried to install a newer version of sendmail last month, but the
author has perversely decided to distribute BSDI-specific makefiles. *sigh*
We are moving the lists to a Linux box because of this, but the timeframe
went to hell when our main AFS disk died without warning. *sigh*
It'll get there eventually ...
