Note: sending this from my personal account to increase odds of someone 
seeing it.  My work address is dmahoney at isc.org.

ISC is having trouble mailing noc at level3.net, we keep getting redirected 
to a messagelabs error, seems to be happening from any address we send 
from, including personal addresses and the (sender/envelope) address of 
our ticket system.

This is probably nonoptimal.

You can reach me voice at 650-423-1362, or our noc number at 650-423-1310.
