3.3 Antispam protection
In the Antispam protection section, you can enable or disable spam protection for the installed mail server,
configure antispam engine parameters and set other levels of protection.
NOTE: It is necessary that the Antispam database is being updated regularly in order for the Antispam module to
provide the best possible protection. To allow for correct regular updates of Antispam database, you will need to
make sure that ESET Mail Security has access to particular IP addresses on particular ports. For further information
on what IP's and ports to enable on your third-party firewall, read this KB article.
NOTE: Also, mirrors cannot be used for Antispam database updates. For proper functioning of Antispam
database updates, ESET Mail Security needs to have access to IP addresses listed in the above mentioned KB article.
Without access to these IP's, Antispam module will not be able to provide most accurate results, thus the best
possible protection.
