I suppose it depends on which option you prefer :)


But, I think if your crontab has many lines then it's a bit easier to
use the method I suggested.


For example:

MAILTO="root"
line1
line2
line3
.....
.....
line9


MAILTO="support-dept"
line10
line11
line12
......
......
line13
line14



MAILTO=""
line15
line16
etc
