Blocking email domains

[subnet_rx]

AOL apparently has me on a spam list so that my confirmation emails are never received. How can I let a visitor know this and not allow aol email addresses?

Banned Email Addresses
Email address ban lists: You may ban any email addresses from registering and posting. Type in the complete email address (user@example.com), or use a partial email address (as in @example.com).

Note that partial email addresses are matched from the end of the address unless you enable "Aggressive Email Banning" below. Therefore if you ban @example.com you will ban user@example.com, but if you ban @example that user will not be banned. If you enable "Aggressive Email Banning", user@example.com would be banned by @example.

If the email address of a user attempting to register or change their email address matches any of the addresses you specify here will see a no-permission error. For example, if you have banned 'example.com' then a user attempting to use 'someone@example.com' will be rejected.

Put a space between each email address or email address fragment.
