All messages, inbound and outbound, routed through Email Gateway Defense are subject to a 300MB size limit. This includes all headers, body, and attached content. This size can be lowered on a per domain basis by contacting Barracuda Networks Technical Support.
Outbound mail scanning includes:
Spam Scanning with Block or Quarantine actions
IP Address Filtering
Sender Domain, Username or Email Address Filtering
Recipient Email Address Filtering
Content Filtering (Subject, Header and Body) with Block, Allow, Quarantine, Encrypt, or Do not encrypt actions
The following tools are not applied to outbound mail:
IP Reputation, a sender authentication mechanism
Sender Policy Framework (SPF), a sender authentication mechanism
To prevent data leakage and ensure compliance with financial, healthcare, and other federally regulated agency information policies, you can require all email sent from any or all configured domains to be encrypted by configuring outbound mail encryption policies on the Outbound Settings > Content Policies page at the domain level.
Inbound and outbound email transmission can also be required over a TLS channel.
