amanda failed to report via email

[Nina Pham]

I have amanda running in a cron job, it suppose to backup 3 things. 
However, for some permission problem, 1 thing is failed to back up. I 
thought it would send the report via email to the email address 
specified in mailto no matter what. But that day, I didn't recieve the 
report via email. When I fix the permission problem, it successfully 
backup and I received email report everyday since then. What might cause 
the problem of sending email? is it a amanda bug? I doesn't make sense 
to me that amanda doesn't send report when there's a problem .
