Bugfix: The SMTP server's 550 in reply to DATA should be
a 554 response. And it wasn't Sendmail. Claus Assman.
Bugfix: the INSTALL.sh test for non-interactive upgrade
broke rooted installations that specify settings via the
environment. Simon Mudd.
Bugfix: mailq output is now really flushed one message at
a time. File: sendmail/sendmail.c.
Feature: "postsuper -d queueID" deletes one message queue
file; "postsuper -d -" reads zero or more queue IDs from
standard input. In order to make this operation usable
with a running Postfix mail system, some routines were made
more tolerant for sudden queue file disappearances. Files:
