Use the Blocked Recipients tab to maintain the Recipient Block list, an administrator-defined list of up to 800 recipients for which incoming messages from the Internet should never be accepted.
By default, recipient blocking is disabled. After you add recipients to the Recipient Block list, you must enable recipient blocking.
- Block messages sent to recipients not listed in the recipient list
To prevent delivery to recipients that aren't in the organization's global address book, select the Block messages sent to recipients not listed in the recipient list option. This feature is maintained through the EdgeSync process. For example, you may want to stop delivery to frequently misused account names, such as firstname.lastname@example.org or email@example.com.
- Block the following recipients
To create an administrator-maintained list of recipients that should be blocked from receiving messages from the Internet, select the Block the following recipients option, type the SMTP address for the recipient, and then click Add. You can enter up to 800 recipients.
To save the changes you have made without closing the dialog box, click Apply.
