Notes:
        - This will not fix the From line in mail to not have routing.
          It has been fixed but will require a new mail binary and the
          size of the binary didn't seem to warrant it at this time.
          This will be forthcoming in the PTF.

This is a TEMPORARY patch to fix several UnixWare 2.01 mail problems.
These problems include:

1. smtpd disappears (this patch will check to see if smtpd is dead and 
   restart if necessary, default cron is every 5 minutes.  You can change 
   this value by editting /var/spool/cron/crontabs/root and restarting cron.  
   If smtpd gets restarted, /etc/mail/smtpd.pid will get removed.

2. Smtp sometimes will hang, causing outgoing mail to backup.  This patch 
   will remove smtp once every half hour, and it will remove the smtp.pid

3. Both the services and inetd.conf files will be updated to allow the 
   popper daemon to function.  TF2057.TAR should be applied to allow the 
   body of the last message in the /var/mail/username queue to appear.

4. A new mailsurr.proto file allows users to send mhs mail addressed to 
   user@workgroup.gateway.  This new file will also fix the problem of 
   accepting mail addressed to the system's domain.  You will still need 
   to select this option under the Admin-Tools --> Mail Setup graphical 
   utility. The new file also provides a commented out line that allows 
   your system to accept mail addressed to user@[ip-addr].  Simply 
   uncomment this line (approx line 50), change 137.65.1.1 to be your 
   ipaddress and rerun /usr/lib/mail/surrcmd/createSurr.  This default 
   mail system should allow your system to accept mail addressed to 
   user@ipaddr (no []).  The file also changes what is placed in the 
   final field for smtpqer, this makes the RCPT field include the 
   destinations system and domain.  This fixes a problem with msmail 
   on the same network, msmail requires the RCPT field to be fully qualified.

5. A new S81smtp allows users to stop and start smtp as well as smtpd, 
   This file will also remove the /etc/mail/smtp.pid file at startup time.  
   This file also redirects the smtpd debug output to /dev/osm 
   (Applications --> Message Monitor). The default debug level is 2, to 
   change the debug level simply find the smtpd line in /etc/rc2.d/S81smtp 
   and change the value from 2 to whatever. You will also need to change 
   the /usr/lib/mail/surrcmd/smtpdcheck file to reflect the new debug level.

6. A new smtpd will also be added.  This new daemon won't fix the problem 
   of the smtpd mysteriously dying, however, it will handle esmtp requests.  
   It will not do emstp but it will respond with an error so the sending 
   system will know to resend its mail as smtp.

7. Smtp will now default to checking for an MX record first before searching 
   for an A record.  To change this behavior, modify the /etc/mail/smtpcnfg 
   file and change MX_FIRST=yes to be MX_FIRST=no.

8. MHS mail will now successfully transfer files from a 1.5 MHS gateway 
   with binary attachements.
