However, the following entries are displayed in the Blocked Senders list only in the Outlook client, not in Outlook Web App:
This behavior occurs because Outlook provides additional Blocked Senders functionality for the inclusion of subdomains when the @ sign is not present in the Blocked Senders domain entry. For example, although @contoso.com filters all senders who have @contoso.com in their email address, contoso.com also filters domain entries that resemble the following:
This helps prevent spam from being delivered to the Inbox when the subdomain portion of the email address has been randomized.
Subdomain filtering for a Blocked Senders domain is a client-side feature and is available only in Outlook, not through Outlook Web App on Exchange Server. Additionally, you can add a domain entry without an @ sign only in Outlook. Outlook Web App adds an @ sign if you try to create a domain entry without one.
To add a Blocked Senders domain in Outlook, follow these steps:
- On the Home tab on the ribbon, click the Junk drop-down list.
- Select Junk E-mail Options.
- On the Blocked Senders tab, click Add.
- Enter the domain entry that you want, and include an @ sign at the beginning of the entry if you want it to also appear in OWA, as in the following figure.
- Click OK, and then click OK again to exit the Junk E-mail Options dialog box.
