why should "yum update" want you to install it? This is not an update. Is it a

Not here, with 1.42-1.fc6 on the system. However, my latest MS version currently 
is 4.71.10. So, there may be something offending with a later version. Or it is 
caused by installing all those Perl source packages from Julian's tarball.
On RH/CentOS systems I strongly recommend *not* to install the complete tar.gz 
you get from Julian's site. Unpack that and *only* (force-)install the 
mailscanner*.rpm plus the tnef rpm and I may be missing another one. Install 
*all* the perl modules that are missing from rpmforge before you install 
MailScanner. Also note, that some of the modules in the tar.gz are already 
included in the installed Perl. There's no need to install these. I once posted 
a list of the modules you have to install for CentOS on this very list (this 
year I think).
I haven't ever had any problems with this approach and enjoy an easy update path 
for the OS *and* MailScanner (and updating MS this way is *much* faster as well) 
and no problems with Perl.
