Very basic questions on imp

[Chandra Mukhyala]

Hello IMP users,

I am brand new to imp.
I have been using IMAP for some time, its runs on my debian linux box.
I want to start using imp now.

I installed the following using debian's packet management system (apt-get)


  horde   1.2.6-1
  imp     2.2.6-1
  php4-imap 4.0.99-3
  php4-mysql 4.0.99-3
  phplib 7.2d-2
  apache         1.3.22-2
  mysql-server   3.23.43-3


I read the FAQ on horde.org and the documentaion which came with imp,
horde and phplib packages and I still have the following questions:

1. What is the purpose of database ? I assume its for storing the mail
files, if so how do we move the existing mail files into the database
I found a script in /usr/doc/horde/examples/mysql_create.sql which
created  active_sessions,auth_userand db_sequence, which sounds like
the database is used only for session info and authentication.

2.How do you configure imp ? Where do you specify information like
your imap server, user name passwd, mail dir ?
I found some .php files in /etc/imp and /etc/horde but i doubt if
I should edit them, I am assuming there is a web based way to configure.

3. How do I access my mail from my webserver ?

I tried myhost.mydomain.com/horde/imp from netscape

it says:
You have chosen to download a file of type: application/x-httpd-php3

what should Mozilla do with this file?
I clicked
. open using php4, but it just save the file  to /tmp/

but I dont know whats the path name for  php3
I have a test.php file in my public_html, I can open that.

If there is any other documentaion I should read,
please direct me there.

Thanks
Chandra.
