just upgraded from 5.5 to 2003, now im in the process of setting up owa. i've had my isp setup to send all http and ssl request to the public ip address, and setup my firewall to send all request from that public address to the email server inside.
internally it works if i just type http://server/exchange
the outside should work with webmail.domain.org
i have mail.domain.org sending to a spam filter.
am i missing something? i set this up on a 2000 server a few years ago just cant remember what i did.
