Hi Lars,

Yes, but this should only affect incoming mail to schubert, not
schubert sending mail.

The reason you no longer get an email on bootup is we no longer
generate it. 

/etc/init.d/loncontrol start

no longer attempts to probe all other hosts and check out the status
of the system.

You can run loncron by hadn or wait until it runs at night to get the
email sent.

Martin Siegert had alot of info about ntp and checking out what it is
doing in the this thread:

Webserver, cron, lonc/d I believe.
