The smart_warning.sh script uses the command line syntax of the 
traditional mail(1) command.

The ssmtp command is not compatible. It emulates the sendmail command 
which requires to prepend header lines (e.g. "Subject") before mail 
text. Therefore "-M exec ssmtp" in smartd.conf does not (and never will) 
work.

Without "-M exec", smartd_warning.sh runs "mail". Please test whether 
/usr/bin/mail exists.

On ubuntu, /usr/bin/mail should be symlinked (via 
/etc/alternatives/mail) to one of the alternative compatible commands. 
Three alternatives are provided by the virtual package "mailx" which is 
a recommended package for smartmontools:

Thanks,
Christian
