Reject Senders
This is the list of disallowed email addresses that cannot send email through your SMTP server and will be rejected before they can send any data. You can use wildcards (e.g. *@*.tw, customerdirect@*.*) or leave blank for no restrictions. Note that this list overrides any 'Allowed Senders' and any 'auto-allowed' senders in the SPAM blocking module.
