Determining why some emails are not being blocked by Barracuda
Answer ID 9780   |   Last Review Date 03/18/2019

Why isn't Barracuda blocking email addresses that are listed on the Block List?

Environment:

Incoming Email, Spam Filtering, Barracuda, SMTP forward
Oracle Service Cloud

Issue:

I have added many email addresses to the Block List in Barracuda, but emails are still coming through Oracle Service Cloud.

Resolution:

The most common reasons for which blocked emails would reach your Oracle Service Cloud site can be related to: 

  • How your SMTP forwarding was configured to redirect emails to the hosted mailbox:

When setting up SMTP forwarding on your external mail server to redirect emails into a hosted mailbox, it is important to specify the full email address which includes the POD your site is hosted on, like support@mailmw.custhelp.com.

  • The email address specified in the Reply-To field of the mailboxes table:

Make sure you specify the full email address (support@mailmw.custhelp.com). Or, if you want to use your company's domain name, then your IT group should configure an SMTP forwarding mail account to redirect emails from "support@yourdomain.com" to "support@mailmw.custhelp.com".

Cause:

When emails are sent to the full address of the hosted mailbox (e.g. support@mailmw.custhelp.com), the emails are processed though the Barracuda filter hosted in the MW pod. If the full address is not used (e.g. support@custhelp.com), email will be processed through the AM pod and use the AM pod Barracuda. Depending on your email setup, the Barracuda that processed the email may not have been configured. By default, when you login to the Barracuda using the steps in the following answer, you are logging in to the pod Barracuda where your site is hosted.

*Note: It is advised that you use the full address of the mailbox instead of an address like support@custhelp.com
