Need help w/Sendmail

[Jennifer McNitt <jenmcnitt@yahoo.com>]

I'm attempting to setup sendmail for the first time and I found that I
need a bit of help.  :)

A bit of background:

I'm currently using Red Hat 5.0 but will probably be upgrading to 5.2
this weekend.

My Linux boxes name is spot.kerowyns-haven.com.  I have setup ListServ
on it to host a couple mailing lists. 

For my example, one of the mailing lists should be delivered from
havenonline.com.  I would also like to setup the server so that
non-listserv mail to havenonline.com can be picked up by pointing an
e-mail program to mail.havenonline.com.

I have setup my DNS file for havenonline.com to have the following
entries:

;mail configuration
havenonline.com.        IN      MX      10      spot.kerowyns-haven.com.
;
;Aliases
;
mail.havenonline.com.           IN      CNAME   spot.kerowyns-haven.com.

In my sendmail.cw file I have added:

havenonline.com

Should that be mail.havenonline.com or havenonline.com?  I would like
e-mail addresses to look like username@havenonline.com not
username@mail.havenonline.com.

Also, I would like to have a couple e-mail addresses such as
'support@havenonline.com' and 'sales@havenonline.com' be redirected to
my kerowyn@kerowyns-haven.com address (or maybe something else). 
Where do I set this up?

One last thing.  It is possible that I'll have another domain where I
would like support@domain.com and sales@domain.com available also. 
Can I do this if I already used the aliases for a different domain? 
Where do I set this up?  I have read something about a virtusertable
but I'm not sure what it is or how to create it.

Is there anything else I need to do to setup this virtual mail system?

Thanks for your help!
