Apache SpamAssassin Configuration
1) Spam score
Each incoming mail is being screened by SpamAssassin and given a score, based on the spam characteristics. By default, email messages with the score 5 are considered to be spam. However, it is possible to adjust the filter according to your needs.
In order to do it navigate to Apache SpamAssassin Configuration widget and click on Configure Apache SpamAssassin.
You will be redirected to a menu where several options are available, setting your own spam score is among them. Find required_score field and insert the new value.
2) Blacklist/Whitelist
Some mails may be incorrectly detected as non-spam by Apache SpamAssassin. If these email messages often come from the specific email senders, you can blacklist them. SpamAssassin will then tag those ones as spam.
To blacklist certain sender, just enter it into the one of blacklist_from fields.
If SpamAssassin often blocks certain email senders and marks its mails as spam (incorrectly), it is possible to add the sender to whitelist.
To whitelist specific sender, just enter it into one of whitelist_from fields.
That's it. :)
