– Enable Partial Address Caching – This is the default setting. Enter a value into the Maximum
Cache Entry field to specify how many entries should be stored in the memory cache. The
default is 10000.
– Disable Address Caching - No addresses will be cached.
• Cache timeout – When Cache All Addresses or Enable Partial Address Caching are enabled,
addresses of all e-mails passing through RiskFilter are checked against the validation server.
E-mails from valid addresses are delivered, and the addresses held in cache for a set time. If an e-
mail is sent from a previously validated address within this cache timeout, the e-mail is delivered
without contacting the validation server. However, if another e-mail is sent from this address after
the cache timeout, the server will be contacted again to validate the address. This setting must be
in valid Integers. The default is 60.
