About antispam policy
Your antispam policy is determined by how you configure Symantec Mail
Security for SMTP to handle spam.
Symantec Mail Security for SMTP can handle spam as follows:
You can also create custom and auto-generated whitelists to let Symantec Mail
Security for SMTP bypass heuristic and blacklist processing for designated
domains and email addresses. (Spam rules still apply.)
Creating a custom whitelist
You can create a custom whitelist of domains so that email messages from those
domains are excluded from all spam processing. If you activate real-time
blacklisting and antispam whitelist exclusion, when spam processing begins,
Symantec Mail Security for SMTP checks the antispam whitelist first and then
queries the real-time blacklists. If the envelope sender matches a domain that is
entered in the antispam whitelist, the email message is allowed. If it does not
match, real-time blacklists are checked. If there is a match, the email message is
blocked.
Email messages from domains that are listed in the whitelist are still processed
for content violations (including spam rule violations) and viruses.
