[Mediawiki-l] Restricting email verification

[Sullivan, James (NIH/CIT) [C]]

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 at mymailserver.com" could successfully create an email
verified wiki account while joe at msn.com would be denied?  All I found in
the archives is that this might require a modification of PHP code.  Any
ideas welcome.
