Error in upgrade

[Denis Beauchemin]

Hello,

I just upgraded from 4.85.2-0 to 4.85.2-1 on RHEL 6.6 and got the following errors at the end of the process :
Installing the MailScanner RPM ... 
Preparing...                ##################################################
mailscanner                 ##################################################

Leaving mailscanner.cf link or file alone.
SpamAssassin site rules found in /etc/mail/spamassassin

To activate MailScanner run the following commands:

service sendmail stop
chkconfig sendmail off
chkconfig MailScanner on
service MailScanner start

Note that you will need to replace the sendmail option
above with your respective MTA. Sendmail, Postfix, Exim, etc.

If you are using Clam AV, ensure that you check that the user
and group specified in /usr/share/MailScanner/clamav-wrapper
matches the user specified in /etc/passwd.

Upgrading /etc/MailScanner/MailScanner.conf

Your old configuration file will be saved as:
/etc/MailScanner/MailScanner.conf.old.40032

Substitution pattern not terminated at -e line 1.
Usage:

RPM
===
If you are using the RPM distributions then try this:

cd /etc/MailScanner
upgrade_MailScanner_conf MailScanner.conf MailScanner.conf.rpmnew > MailScanner.new
mv -f MailScanner.conf MailScanner.old
mv -f MailScanner.new  MailScanner.conf

TAR
===
If you are using the tar distribution so that the old version is in
/opt/MailScanner and the new one is in /opt/MailScanner.new then:

cd /opt/MailScanner.new/etc
../bin/upgrade_MailScanner_conf /opt/MailScanner/etc/MailScanner.conf /opt/MailScanner.new/etc/MailScanner.conf > MailScanner.new
mv -f MailScanner.conf MailScanner.old
mv -f MailScanner.new  MailScanner.conf

NOTE
====
To keep your old comments in your original file, add "--keep-comments"
to the command line.  Note that this will mean you don't get to find
out any extra new values you might be able to use in existing "improved"
configuration options.

No .rpmnew file, so just copying your existing .conf file.
