subdomain and mail relay configuration

[aranthorn]

I used the perfect server for fedora 7 configuration following the step by step instructions here: http://www.howtoforge.com/perfect_server_fedora7

Thanks to Falco for putting that together, BTW!

But I have a couple issues.

#1
I can't get my subdomain to work (images.dancingmokey.com)
When I go to http://www.dancingmokey.com/images/ I get a 403 error
When I go to http://images.dancingmokey.com/ I get

This IP address is shared. For access to the web site which you look for, enter its address instead of its IP

I'm at a loss.


#2
Also, when someone uses a contact link from the forum installed (vBulletin 3.6.8), I get the email just fine, but when I try to reply I get:

Your message did not reach some or all of the intended recipients.

554 5.7.1 <removedbyme@yahoo.com>: Relay access denied

What can I do? I'll post any information asked for, but I went through that perfect server setup word for word. Everything else works fine.

Thanks in advance and yes, I did search these forums before posting
