it's been that way since 2003 when somebody complained about
smtp as default (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=152729);
personally i prefer pipe for submission and nobody asked for a different
default yet, hence...

as far as i can tell yes, because verify_all_addresses uses do_an_address which
uses sm_wadr which talks smtp.

this idea would also not work for postfix: its sendmail
emulation wrapper does have a '-bv' option, but one which never responds
to the invoking process (like real sendmail does); instead postfix
sends an email report back after verifying each recipient address.

personally i think spending any further effort on verifying addresses for
deliverability on the sending side is wasted because of how little
verification/guarantee it provides (see bugs section in man whom).
