The new cf appeared to be a 'fresh' default config file.

i.e. only bound to localhost, all my amavis and rbl stuff was missing, etc.

Heres the build info from the sendmail.cf post upgrade:

##### built by mockbuild at turbosphere.fedoralegacy.org on Wed Mar 22 
23:27:38 EST 2006
##### in /builddir/build/BUILD/sendmail-8.12.11/cf/cf
##### using ../ as configuration include directory

It looks like it just completely overwrote my sendmail.cf with a bog 
standard config.

It shouldn't do that. It should either create its own sendmail.cf as 
sendmail.cf.rpmnew, or move the existing one to sendmail.rpmsave and 
then replace it.

Thats not present in my sendmail.cf at all.

In this case, pretty much everyone is going to be running a non-standard 
configuration if they're running a mail server, because the standard 
configuration only binds Sendmail to 127.0.0.1.
