The Barracuda Email Security Service may be configured to scan outgoing mail simultaneously with scanning inbound mail. To enable spam and virus scanning of outbound mail, follow the steps below.
In this article:
From the OUTBOUND SETTINGS > Sender IP Address Ranges page:
Each IP address from which you want to allow outgoing mail through the Barracuda Email Security Service must be listed on this page. The Logging Domain is the domain name that will appear in the Message Log as the sending domain for the associated IP address.
To relay outbound mail through the Barracuda Email Security Service, in your mail server or Smart host, specify the hostname value from the Outbound Hostname field on the DOMAINS > Domain Manager page for each domain from which you'll be relaying outbound mail.
Check the DASHBOARD and MESSAGE LOG pages to make sure that inbound and outbound messages are being logged for the selected domain. The Message Log page provides rich searching using a set of keywords with your search words or phrases. See The Message Log for more information on filtering messages.

The following scanning tools are not applied to outbound mail:
To prevent data leakage and ensure compliance with financial, health care and other federally regulated agency information policies, you can require all email sent from any or all domains configured in your Barracuda Email Security Service to be encrypted. Create policies for encryption of outbound mail in the OUTBOUND > Content Policies page at the domain level. See How to Use DLP and Encryption of Outbound Mail for more information.
Transmission of inbound and outbound email can be required over a TLS channel as well - see Secured Message Transmission for details.
The Barracuda Email Security Service can append a custom text and/or html footer to each outbound message, configurable at the global level on the OUTBOUND SETTINGS > Tagline/Footer page.
