For example: |(mail=%email%)(user=%user%)(ou=Engineering)
Mail Field – The field in the LDAP query that contains the e-mail address to be imported.
Cache Setting – Select the option that corresponds to how you want to treat Address Caching: 
– Cache All Addresses – All addresses will be cached.
– 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. The default is 60
.
