[Dbmail] Adding a return code to dbmail-adduser and dbmail-maintenance

[Jacques Beaudoin]

I use dbmail-adduser and dbmail-maintenance in bash scripts via the 
webmin interface.

I get this way a easy to use web administration tool  for dbmail.
If dbmail-adduser and dbmail-maintenance could return a execution code 
(errorlevel).

I could use the bash "if command"  to check if dbmail-adduser or 
dbmail-maintenance executed with no errors.

Exemple  dbmail-adduser ................: 
               if [$? != 0];  then
               ........
              else
              .........
              fi
              
Could  this  be added to dbmail-adduser and dbmail-maintenance 

Thanks
Jacques
