Whitelist and blacklist addresses are now file-glob-style patterns, so, *, or * will all work. Only * and ? is allowed in the “blacklist_from” and “whitelist_from” field. = This will blacklist/whitelist a single email account.
* = This will blacklist/whitelist all email account under the domain
? = Question mark ? blacklist or whitelist a single character. Example :, etc

You can adjust the “Required score” in SpamAssassin settings. By default the SpamAssassin score will be 5 and you can change it to a higher or lower value.

If the score is 0, then all the emails will be marked as spam. Do not set 0 score in SpamAssassin settings.

Score below 5 is strict and it might block legitimate emails ( more spam emails will be blocked if score is less than 5 and might accidentally block some legitimate emails).
