Lewis In an ongoing effort of converting a number of Openserver Systems
from mmdf to
sendmail I have written a pretty well tested guide on how to do it. I
hope someone
can find this usefull.

Installing Sendmail 8.11.x on SCO OpenServer 5.0.x
August 20, 2002

Introduction To thwart the ever-growing problem of junk and spam email,
which in many
cases cripples systems and daily business operations it will be
necessary to convert
a growing number of systems to newer and more secure methods of
mail deliver.
Methods to implement include the blocking of mail relaying through
systems. Checks
of who is sending mail and who is authorized to do so. Creation of
blacklisted
senders from which mail will always be rejected. Creation of white lists
specifying
each individual who is allowed mail access while denying all others.

Advantages of Sendmail over MMDF

a_ Better Relay checking b_ Reverse DNS failure rejection c_ Hosts,
user, and network
access restrictions applicable d_ Better industry support, documentation
and ongoing
development over MMDF or similar mailers. e_ Graphical Administration
tools available
for most environments including SCO OpenServer 5.0.x f_ Ability to
add custom
features like blocking incoming mail with listed words in subject.

*** Preparing for Upgrade ***

1. Backup the usr mail files in /usr/spool/mail/ ( cp -rp
   /usr/spool/mail
/usr/wwi/backup/ ) using -rp flags to preserve permissions on mail
spool files.
Uninstalling mmdf or sendmail will remove all files in /usr/spool/mail/

Backup the mmdf aliases file. This will later be appended to
/usr/lib/mail/aliases
for sendmail
( cp /usr/mmdf/table/aliases /usr/wwi/backup/ )

Backup the mmdftailor config for reference
( cq /usr/mmdf/mmdftailor /usr/wwi/backup )

2. To uninstall mmdf issue ( custom -p SCO:odtes -d SCO:MMDF )

3. By default Openserver 5.0.5 has sendmail 8.8.8b installed. You
   should not use
this as many known exploits exist for this version of sendmail. Also
many of the
anti-spam features of sendmail are not fully implemented in this
version. The
newest complete Sendmail package available from SCO is part of
supplement rs506a
meant for Openserver 5.0.6. Included is Sendmail 8.11.0. This
supplement will
work on Openserver 5.0.5 and should also work on Openserver
4..4

*** Downloading the Software ***

5. Download rs506a.tar at ftp.caldera.com
/pub/openserver5/rs506a/rs506a.tar

6. ( scoadmin software) Select Install new from Media Images.
   This will list
several different components, which can be installed. Only select
Sendmail and
install. The installation procedure will have an error. Ignore this
error with
'i' and continue the Sendmail installation.

7. Now download the sendmail.8.11.0.tar.Z from
   http://www.planetmirror.com/pub/sendmail/past-release-
s/ sco-generic.mc (is appended at the end of the article). This is a SCO
Openserver specific config file I created. We are only downloading
the sendmail
distribution to get the m4 make files for sendmail.cf

8. Uncompress and untar sendmail.8.11.0.tar.Z in /usr/local/
( cd /usr/local/sendmail.8.11.0/cf/cf ) ( cp sco-generic.mc
/usr/local/sendmail.8.11.0/cf/cf )

Hello Matt,

I've never dealt with sendmail before, after having a few problems I
found this document, it makes sence except for  the section  -
(cp sco-generic.mc /usr/local/sendmail.8.11.0/cf/cf
There is no sco-generic.mc and the cp command is copying it to the same
directory.
My apologies if I'am being stupid but any help would be appreciated.

Thanks
Justin
