I did, as much as I was able. I was slightly limited by my server's abilities and not able to test everything 100% thoroughly, but everything that I was able to test worked correctly. Why, did you have a problem?

I am using *.aol.com as a wildcard. I have tested this on an AOL dialup account, and it has given me the message of "Our system shows that you have already registered under a different name".

I am receiving many emails from users from AOL not being able to signup.

any ideas?

1) Are you sure your server resolves hostnames? I'd recommend making a phpinfo script and checking.
2) Are you sure that the hostname actually ends in .aol.com?

1) I can access my phpinfo file. What am I looking for? I searched the page for "resolve" or "hostnames"...not much came up. Do you have that script or know where to get it to find out?

2) *aol.com or .aol.com? I see you put .aol.com

1) Look for a variable called "REMOTE_HOST"... it should be under the "Environment" section, probably next to "REMOTE_ADDR."
2) Either one should work, but *aol.com might allow unlimited registrations from someone coming from a host like maol.com :p

Also, could you go to this website with the AOL connection and let me know what it says that the hostname is?

Krofh, check your PMs

Updated to 1.0.5... the "Allowed Hostnames" bit only worked with hosts resolving REMOTE_HOST, and it seems that wasn't an option enabled by default in Apache. Now it resolves hostnames independently through PHP from REMOTE_ADDR.

updated mine!

Is the hostname bit working for you now?
