In general adding whitelist entries in SpamAssassin can be done by creating a custom SpamAssassin cf
For whitelisting a single address you may use one of the following syntax
to whitelist all senders from a single domain.
We recommend to create a new cf-file at C:\ProgramData\JAM Software\spamdService\sa-config
and name it e.g. xWhitelist.cf. That way your custom whitelist will be parsed quite late during startup, thus preventing that any of your settings gets overridden by another config file. Please note that you
have to manually restart SpamAssassin Daemon control service to apply your changes.
Yes, the SpamAssassin used checks SPF records. The default settings for SPF can be found in 25_SPF.cf or the corresponding scores in 50_scores.cf. If you are using "Exchange Server Toolbox" the best way to set your own scores is to use the built-in editor for creating custom SpamAssassin config files which you can find under Spam Options.
For more information about the options, see:
Alternatively, you can manually create your own .cf file in which you define your "rules", this should only come last alphabetically, since SpamAssassin will evaluate the cf files in numerical-alphabetical order. (For example XMySettings.cf).

URIBL (http://www.uribl.com) is a DNS-based Blackhole List which tracks IP addresses which are commonly used for sending spam mails. URIBL is enabled by default for SpamAssassin installations but allows only a certain amount of requests from the same IP every day. If this amount is exceeded, any further requests will be blocked by the URIBL servers with the info notification above.
This typically happens for SpamAssassin installations that use public DNS resolvers such as Google. As any request that is forwarded via the Google servers has the same IP when it reaches the Blackhole list, all requests will share the same limit. For usage of an alternative DNS, please follow these instructions.
For the following domains it is currently useful to set up forwarding to ensure the full functionality of SpamAssassin:
Now determine the name server for each of the mentioned domains.
Open a command prompt and issue the following command (e.g. for "lists.dnswl.org"):
nslookup -querytype=ns list.dnswl.org.
list.dnswl.org nameserver = b.ns.dnswl.org
list.dnswl.org name server = c.ns.dnswl.org
b.ns.dnswl.org internet address = 126.96.36.199
c.ns.dnswl.org internet address = 188.8.131.52
c.ns.dnswl.org AAAA IPv6 address = 2600:3c01::21:1000
