There are lots of things about the bootup I don't understand.  Since the 
firewall is always on and connected to the ISP, there shouldn't be an 
unusual delay, should there?  After things get started everything seems to 
be operating properly.

Since the laptop has wireless, is it possible it is trying to connect that 
way instead of with the ethernet cable?  If so, it is strange that it 
indicates [ OK ] for sendmail and SM-client when it finally gets done.

I don't know if it is pertinent, but just before the attempt at starting 
sendmail, "Synchronizing with time server" always fails after one minute. 
This is followed immediately by "Starting NTPD" which always gets [ OK ].
