h_errno now in conf.h

back out check for /etc/sendmail.cf change -- instead, just
always use sendmail.cf directly

release HUP signal before re-execing sendmail

try short host name for files hosts service (as well as nis)

if /etc/sendmail.cf exists, use it regardless of existence of
vendor path

allow trusted users to have untrusted shells

updates for A/UX

tweak a couple of #if => #ifdef for compile purposes

make a bunch of #defines into 0/1 instead of ifdef/ifndef

make sm_getpwuid definition match prototype; move some debugging

fix definition for ANSI compilers

TRY_VERSIONED_CF_NAME is a botch -- consider mailstats

more clever connection refusals

improve case where service.switch exists but is missing a service

print OS compile flags (sigh)

non-DEC OSF/1 doesn't have svc.conf

freespace=>freediskspace, enoughspace=>enoughdiskspace to avoid
conflicts with some memory allocators (e.g., A/UX)

default prog mailer must have internal form of $u

add trace flags in sm_gethostbyname

change OA semantics so that all .cf entries are mapped into the
"files" or "local" alias service type

implementation of aliases that puts first unqualified A option
as local; rest of A options after switched lookup

put use of getconfattr() on a separate USEGETCONFATTR compile flag;
in my opinion getconfattr() is fundamentally misdesigned

try using getconfattr to find legal shells on AIX

try to fix a compile glitch on some HP-UX installations

lint
