SpamAssassin Basic Configuration Settings

Settings	Explanation	Önerilen Değerler
Spam Filtering Status	Checks whether SpamAssassin is enabled.	Effective
Required Score	The minimum score required for an email to be marked as spam.	5 (Can be lowered for more stringent filtration)
White List	Email addresses that are always considered reliable.	Trusted business partners, family members
Blacklist	Email addresses that are always considered spam.	Known spam sources

Each email is assigned a spam score based on its content and other characteristics. Emails exceeding a certain threshold are marked as spam. Lowering this threshold may result in more emails being marked as spam, while raising it may reduce the effectiveness of spam filtering. Therefore, it's important to set this threshold carefully and optimize it by monitoring performance over time. You should also determine how emails marked as spam will be handled.

The default value is usually 5, but it can be lowered or increased. A lower value results in more emails being marked as spam, while a higher value makes spam filtering less sensitive. Careful configuration of this setting is important to balance false positives (i.e., normal emails being marked as spam) and false negatives (i.e., spam emails landing in the normal inbox).

Setting Name	Explanation	Recommended Value
required_score	The minimum score required for an email to be marked as spam.	5 (6-7 for low sensitivity, 3-4 for high sensitivity)
rewrite_header Subject	Adds the [SPAM] tag to the subject of emails marked as spam.	[SPAM]
report_safe	Sends the content of spam emails as a report.	0 (Off) or 1 (On)
whitelist_from	It ensures that emails from trusted senders do not pass through the spam filter.	[email protected]

Also, SpamAssassin auto_learn Another important setting to consider is the "SpamAssassin" feature. This feature allows SpamAssassin to automatically learn from incoming emails. By marking emails as spam or not spam by users, SpamAssassin can filter more accurately over time. However, if this feature is enabled, it is recommended that the system be regularly inspected to protect against false positives.

Important Settings

• required_score: Set the spam threshold value.
• rewrite_header Subject: Mark the subject of spam emails.
• report_safe: Configure spam reporting options.
• whitelist_from: Whitelist safe senders.
• blacklist_from: Add unwanted senders to blacklist.
• auto_learn: Enable/disable automatic learning feature.
