You need to configure sendmail. Tech support told me to directly edit the relay setting in submit.cf but that seemed to apply to an older version of sendmail.

Anyway, this works on 6.5.x. I only made the changes on node 1, which in my case calls itself Isilon-1. I have various scripts that send mail on a daily basis (one just sends the output of isi stat every morning). This didn't have any effect on the normal email sent from the cluster, I think that actually uses a different mechanism.

Back up the files in /etc/mail first, of course.

cd /etc/mail

make (generates hostname.mc and hostname.submit.mc - in my case node 1 calls itself Isilon-1 so I get Isilon-1.submit.mc)

Edit [hostname].submit.mc and add everything from ADDED LINES to END ADDED LINES below (the masquerade and SMART_HOST lines), then "make all install restart". It should be good to go (assuming your relay host is set up to accept mail from your cluster).

Richard,

Do you know whether or not the scripting you are running is isolated to the node it was created on, node 1? I believe this will be the case.
