in your signup.php file near:

PHP Code:

<tr valign=top><td align="right" class="heading">Email address:</td><td align=left><input type="text" size="40" name="email" /> 


append:

PHP Code:

<select name="maildomain"><option value="@gmail.com">@gmail.com</option><option value="@yahoo.com">@yahoo.com</option></select> 


you can use as many option values as you may.

in takesignup.php:

PHP Code:

if (!mkglobal("wantusername:wantpassword:passagain:email))
die(); 


replace with:

PHP Code:

if (!mkglobal("wantusername:wantpassword:passagain:email:maildomain))
die(); 


PHP Code:

if (!validemail($email))
    bark("That doesn't look like a valid email address."); 


replace with:

PHP Code:

if (!validemail($email.$maildomain))
    bark("That doesn't look like a valid email address."); 


replace:

PHP Code:

$a = (@mysql_fetch_row(@mysql_query("select count(*) from users where email='$email'"))) or die(mysql_error()); 


with:

PHP Code:

$a = (@mysql_fetch_row(@mysql_query("select count(*) from users where email='$email.$maildomain'"))) or die(mysql_error()); 


and in the big query:

INSERT INTO users (username, passhash, secret, editsecret, email....

where you see $email

replace it with $email.$domain.

And thats about it!

An alternative solution is to create a table like maildomain where you can put allowed domains.

Note: this is done with tbdev source. Didn't had the time of installing tstrike but the differences are not that great.

Cheers.
