[Mimedefang] SA upgrade difficulty

[NFN Smith]

I have a box on which I have RedHat 7.3, sendmail 8.12.8, MIMEDefang 
2.25 and SpamAssassin 2.64.

I'm working on upgrading SpamAssassin to 3.0.3, and as a result, I'm 
finally getting MIMEDefang updated to 2.53.  However, the upgrade 
process is going rougher than I expected, and I need a little help on 
cleanup.

Things I've done:

1) The upgrade I'm installing is a .RPM from dag.wiers.com, 
mimedefang-2.53-1.0.rh7.rf.i386.rpm.

When I installed with rpm, rpm reported conflicts with most of my 
existing MIMEDefang files, including mimedefang-filter, the init script 
in /etc/rc.d/init.d, /etc/sysconfig, the mimedefang binaries and perl 
scripts installed in /user/bin, and man pages.  I reran the rpm install 
(perhaps unwisely) with the 'force' option.  From there I got .rpmnew 
files for mimedefang-filter and /etc/sysconfig/mimedefang.

2) Since I didn't see anything obvious for keeping the existing 
sysconfig, renamed that one to a backup name, and copied the .rpmnew 
file to be the primary file.

On mimedefang-filter, our existing script has some custom coding in it, 
so I did the minimum necessary for upgrading the script, renaming the 
md_log and md_log_enable settings to md_graphdefang_log and 
md_graphdefang_log_enable, respectively.

3) Following starting the mimedefang daemon, I got log errors noting 
errors noting that Unix::Syslog was not found, specifically not finding 
./Unix/Syslog.pm.  I resolved this one by copying 
/usr/lib/perl5/5.6.1/i386-linux/Sys/Syslog.pm to 
/usr/lib/perl5/5.6.1/i386-linux/Unix/Syslog.pm.

4) From there, following restart of both sendmail and MIMEDefang, things 
seem to be working mostly correctly, but I am seeing some log errors on 
an inbound message coming from yahoogroups, and slaves dying unexpectedly.

I've quoted relevant log entries below.

I think I'm missing something small here, but I'm not sure of what to do 
next to fix this one.  For now, the only place I'm seeing this is with a 
single yahoogroups message, and I'm not especially concerned if that 
particular message gets lost.  However, to me, it seems that something 
isn't quite right, and I want to get that fixed, before I move on to 
upgrading SpamAssassin, and replicating my updates to several parallel 
servers.
