[Antonio Ospite <ospite@studenti.unina.it>]

t/README recommends chaining test assertions.

Hi,

there are a couple of tests I didn't fix here, they are storing intermediate
return values, see "confirm by default (due to cc)" and following in
t/t9001-send-email.sh

I don't know if chaining is correct already there.

Thanks,
   Antonio
