Yes, exactly.

It *is* supported by mutt using the following trick: one of the arguments
to mutt is:
.... | mutt -d4 -e "set sendmail=\"cat --\"" ... | sendmail -t
i.e. from the point of view of mutt the 'sendmail' is just a 'cat'
command and so its output is coming out on STDOUT of the proc.
I'm already debugging the process chain with Linux strace and it seems
that there is some problem with SIGCHLD in mutt not getting correctly
the proc termination of its 'sendmail', seeing it as -127 which causes
then the (wrong) assumption that the mail wasn't sent by its 'sendmail'
child proc. We will see...
