using exim4 w/ Hardy and/or Intrepid

[Robert Holtzman]

Just installed rkhunter and exim4 automatically tagged along. A post 
here some time ago informed me that Ubuntu doesn't use an MTA but I 
think I'd like to try running everything thru exim4 so I can call 
spamassassin from it. Now I'm running fetchmail and delivering to 
procmail and it shows up in ~/mail. How that happens w/o an MTA is 
beyond me (if anyone can point me to a lucid explanation of that I would 
be grateful). I suspect the answer is to simply have fetchmail deliver 
to exim4 and I *think* exim4 will automatically pass it to 
procmail....but I'm not sure.

I've never played with this before, always accepting the distro's 
default. I haven't been able to find any docs pertaining to this 
specifically. Anyone have any pointers, sources, flames, etc?
