SMTP Blocked Senders

The SMTP Blocked Sender list is an effective method for temporarily canceling a domain or indiviual user's ability to send email on the server. For example, if a particular account is sending an abnormal amount of email, you can add their address to Blocked Senders and they will be unable to send email until you remove them from the Blocked Senders list. Users and/or domains can be left on the list for whatever time you deem appropriate, and can be an effective stop-gap versus actually deleting the user and/or domain from the server.

To get started, click on the Security button on the main toolbar, then select SMTP Blocked Senders from the Security folder tree view.

Blocked Senders - Enter the email addresses or domain names you want to block, one per line. The asterisk (*) wildcard symbol is permitted in the list.
