All versions of upgrade_MailScanner_conf are pretty much the same. It's 
what you pass to it on the command-line that tells it what to do. Diff 
the two scripts and you will find they are identical, pretty much. I 
occasionally add a new test, but the differences don't basically affect 
its operation.

Yes. If you have modified any of the report files you might want to copy 
the old ones to the new one as well. If you have edited languages.conf 
then there is an upgrade_languages_conf script as well (which is 
actually a soft-linked copy of upgrade_MailScanner_conf :-)

The only interface from sendmail to MailScanner is through the 
filesystem. The only sendmail call that MailScanner makes is to kick it 
into doing a delivery attempt of each new message as soon as it has been 
processed. It does that by running "Sendmail2" as defined in 
MailScanner.conf.
