IP Analysis Outbound

  • Last updated on

After applying rate controls, the Barracuda Email Security Gateway performs analysis on the IP address, applying quarantine, block, encrypt or redirect policies that you configure in the BLOCK/ACCEPT pages.

BLOCK/ACCEPT policies created at the per-domain level do NOT apply to outbound messages. So, for example, navigating to the DOMAINS page, then clicking Manage Domain for a particular domain, then configuring policies on the BLOCK/ACCEPT pages ONLY applies to inbound messages for that domain.

Once the true sender of an outbound email message is identified, the intent of that sender should be determined before accepting the message as valid, or "not spam". The best practice is to know the IP addresses of trusted senders and known forwarders of email and define those on the Barracuda Email Security Gateway as "Allow Listed" by adding them to a Allow List of known good senders (see the BLOCK/ACCEPT > IP Filters page). Various methods for discerning "good" senders of email versus spammers are described in this section to help you to quickly configure your Barracuda Email Security Gateway per the needs of your organization.

Barracuda Networks does NOT recommend adding domains to the Allow List because spammers will spoof domain names. When possible, it is recommended to only add IP addresses to the Allow List.

Important: Any IP addresses you add to the Allow List (the Allowed IP/Range section of the BLOCK/ACCEPT > IP Filters page) bypass Rate Control, spam scoring, and all other block lists. Virus scanning still applies.
