Hi Alexandre,

Short answer: email may be coming from the compute nodes. Is your  
cluster set up to correctly handle this case?

In SGE 6.x and later, email is generated by the sge_execd which means  
it comes from the compute node where the job ran. Many clusters I've  
seen have managed to set up mailhandling correctly on the head/master/ 
portal systems but in some cases they have neglected to configure for  
proper smarthost and mail relay coming from messages generated by  
compute nodes.

You may want to login to a compute node and confirm that your  
"sendmail myemail at domain.com" works. Check the logs on the compute  
node including the mail logs if you have access as well.

One other suggestion -- I often configure clusters so that user mail  
can only be delivered to the local user spool on the login/master  
node -- external mail relaying is prevented. We do this so that  
someone launching a bad array job does not swamp the organizational  
SMTP server with a few thousand error messages each time the job fails.
