correct, but you can enter an enhancement issue for it.

The emails are send from the nodes. But all qrsh tasks which ended  
before reported their usage to the qmaster, which will write the  
accounting record after some seconds when the job finished. Hence  
this final notification email would have to be send from the qmaster  
then.

Rough idea for the qmaster as a workaround:

tail -F --follow=name -n 0 $SGE_ROOT/default/common/accounting 2>/dev/ 
null | my_mail_script &

and the my_mail_script is an endless loop which greps <job_id> and  
<user> out of the entry, then issues a `qacct -j <job_id>` and sends  
this well formatted output to the determined user (well, you can't  
use -M then in the future).
