HTTP Config in Zimbra

[the_griz]

I am using:
Release 5.0.9_GA_2533.RHEL5_64_20080815094512 RHEL5_64 FOSS edition

I am trying to find where some items are configured in Apache.
- config for admin port of 7071
- default ssl config for admin port of 7071
- config of webmail port of 80 (** see below)
- where to put ssl cert information for webmail interface

** my Zimbra install will handle mail (imap, smtp) on one IP and use a different ip for webmail..com. I changed the IP in the Listen directive in /opt/zimbra/httpd/conf/httpd.conf but now the webmail client responds to both http://mail..com and http://webmail..com (which are different IPs).

Thanks!
