Hi all,

we have some (testing) SL6 installations and we're seeing that some
things have changed between SL5 and SL6.

I've read
http://www.scientificlinux.org/distributions/6x/features/differences
and found the yum.conf issue we faced, but now we've found that
sendmail is not the default mail server, now it's postfix.

So, I'm wondering if someone has some more detailed document about
SL5/SL6 (or maybe this is RH5/RH6 related) differences.

Many thanks in advance,
Cheers,
Arnau
