System appeared to reject relay attempts
Connection closed by foreign host.
"System appeared to reject relay attempts" ah, that's what we're

:
Wanting to SYNCHRONIZE YOUR SYSTEM CLOCK periodically? If you
think your system clock gathers or loses a few extra seconds
each day, you're probably looking for "ntp" which queries
several "network time protocol" servers, and sets your system
clock accordingly.
apt-get install ntp ntp-simple ntp-doc ntpdate
then browse /usr/share/doc/ntp-doc/html for info.
