When the configuration is set to require email verification when creating an account by setting $wgEmailConfirmToEdit=true, is there a way to restrict account verification to spscific mail addresses such as "mymailserver.com" addresses. So for example, a user using the email address "joe@mymailserver.com" could successfully create an email verified wiki account while joe@msn.com would be denied? All I found in the archives is that this might require a modification of PHP code. Any ideas welcome.
