I am ok with any 8.0.4 links as well if you have them. It has been a while but I seem to remember something about dns being an issue and wondering if anyone can point me in the right direction for installation so I dont have to be searching for 6 hours about how to install it on ubuntu. Thanks.
Also, what ports do I HAVE to have open for the mail to be delivered? Just smtp 25? How about user access ? 80 and 443 (7071 for admin)?
