apache won't start

["Dr. Scott S. Jones" <scott@fyrenice.com>]

Dear List:

I am baffled. I had apache working in the past, serving up files from
Mailman, Mambo and SugarCRM. Now, though, my apache installation won't run. 

I just installed mailman with apt-get install mailman and it ran without a
hitch, the installation. However, loading my web sever, at
http://fyrenice.com just renders now an error: The connection was refused
when attempting to contact fyrenice.com. 

I check in /var/log/apache, after attempting to load http://localhost/ and
http://fyrenice.com/ and even the discreet IP number..and all render the
error message above. 

What am I doing wrong here? 

Scott
