Anti-Spam Features
Specific Access Patterns
Specific Access Patterns (SAP) can be used to either accept or reject mail. These rules overrule all
others, allowing them to be used for special cases to allow email where it would be otherwise
blocked, or to block email when it would otherwise be allowed. Specific access patterns allow an
administrator to respond to local filtering requirements such as the following:
• Allowing other systems to relay mail through ePrism
• Rejecting all messages from specific systems
• Allowing all messages from specific systems (effectively whitelisting the mail)
It is recommended that you use Pattern Based Message Filtering for anti-spam control and white/
black listing. See “Pattern Based Message Filtering” on page 107 for more detailed information.
Configuring Specific Access Patterns
Select Mail Delivery -> Anti-Spam -> SAP on the menu to configure specific access patterns.
• Pattern Based Message Filtering — Enable this option to use Pattern Based Message
Filtering to reject or accept mail based upon matches in the message envelope, header, or body.
This type of filtering is explained in more detail in the next section.
• Maximum recipients per message — Set the maximum number of recipients accepted per
message. A large amount of recipients can indicate a spam or bulk message.
