sendmail R option

[bh at cs.brown.edu]

SunOS 4.X.X sendmail takes an OR which also takes an optional hostname
argument.  If no hostname argument is specified it opens up /etc/mtab to
try to find if /var/spool/mail is NFS-mounted.

the sendmail.cf can essentially be reduced to (one line):

	ORmailserverhostname

however.... this type of forwarding does not make use of
/var/spool/mqueue.  so, if the mailserver is down and you send mail and if
your machine goes down before the mailserver comes back... you lose the
message.  The OR module uses its own method of retrying. (a while loop,
basically!)

the Os ("super safe") option is ignored if the OR option is set.

I reported this as a bug to Sun and have heard no response.
