Limiting registration to users of one email domain.

I am just unsure of how to accomplish it. Any help or guidance would be greatly appreciated.

OK, here it is quick and dirty:

In your Admin Panel Options there is an area for email banning. (Which is the opposite of what you want as stated above.) What I have done is to allow you to reverse that function to only allow those who are listed.

Here you go:

Open includes/functions_user.php

Find This (Around Line 436)

// ###################### Start checkbannedemail #######################
function is_banned_email($email)
{
	global $vboptions, $datastore;

	if ($vboptions['enablebanning'] AND !empty($datastore['banemail']))
	{
		$bannedemails = preg_split('/\s+/', $datastore['banemail'], -1, PREG_SPLIT_NO_EMPTY);

		foreach ($bannedemails AS $bannedemail)
		{
			if (is_valid_email($bannedemail))
			{
				$regex = '^' . preg_quote($bannedemail, '#') . '$';
			}
			else
			{
				$regex = preg_quote($bannedemail, '#');
			}

			if (preg_match("#$regex#i", $email))
			{
				return 1;
			}
		}
	}

	return 0;
}



REPLACE WITH:


// ###################### Start checkbannedemail #######################
function is_banned_email($email)
{
	global $vboptions, $datastore;

	if ($vboptions['enablebanning'] AND !empty($datastore['banemail']))
	{
		$bannedemails = preg_split('/\s+/', $datastore['banemail'], -1, PREG_SPLIT_NO_EMPTY);

		foreach ($bannedemails AS $bannedemail)
		{
			if (is_valid_email($bannedemail))
			{
				$regex = '^' . preg_quote($bannedemail, '#') . '$';
			}
			else
			{
				$regex = preg_quote($bannedemail, '#');
			}

			if (preg_match("#$regex#i", $email))
			{
				return 0;
			}
		}
	}

	return 1;
}

What this has done is to switch the "return 0" and "return 1"

If you have any trouble with the above code let me know.

BTW: I did fully test this and it worked on my test BB.
