8.04 MTA?

[Robert Holtzman]

I see that sendmail is not the default MTA. I can't find what is. 
Searching the system shows no postfix, exim4 or anything else that I can 
find. Running a search on "ubuntu 8.04 MTA" came up with an entry for 
their server guide I found amusing. It states that postfix is the default 
MTA then goes on to give instructions on installing and configuring 
postfix. If it's the default, why are they telling you how to install it? 
Anyone have an explanation?

Thanks.
