Managing Spam Filters
Your SiteForge email service includes advanced spam filtering tools that help you keep unwanted emails out of your inbox while ensuring that legitimate messages are delivered correctly.
This guide explains how to configure and fine-tune spam protection settings directly from your hosting panel or webmail.
Accessing Spam Settings
You can manage spam filters either through:
- the Hosting Panel under Email Accounts → choose the mailbox → Spam Settings
Spam Filter Configuration
1. Spam Folder Threshold
All incoming emails are automatically scanned and assigned a spam score based on various filters.
Messages that exceed your set spam threshold are moved to the “Spam” folder.
You can adjust the threshold from Strict (low value) to Lenient (high value) depending on your preferences.
- Strict (e.g. 4): More aggressive filtering — higher chance of catching spam, but may also flag legitimate mail.
- Lenient (e.g. 8): Allows more emails through — fewer false positives, but slightly more spam.
📁 The “Spam” folder is available in both Webmail and IMAP clients.
2. Rejecting High-Risk Spam
For emails with an extremely high spam score, you can choose to reject them automatically.
Rejected emails are not delivered to your mailbox, and the sender’s server usually receives a bounce message confirming non-delivery.
This helps reduce storage use and protects you from potentially harmful attachments or phishing attempts.
3. Greylisting (Temporary Rejection)
Greylisting is an additional layer of defense against spam bots.
When enabled, suspicious messages are temporarily deferred.
Legitimate mail servers will retry delivery after a short delay (usually around 5 minutes), at which point the message is accepted.
This method effectively filters out a large portion of spam sent by servers that don’t retry deliveries.
4. Whitelist & Blacklist Management
You can explicitly define which senders are always allowed or always blocked:
-
Allowed (Whitelist):
Emails from addresses or domains on this list bypass all spam checks and are always delivered. -
Blocked (Blacklist):
Emails from these addresses are automatically rejected before reaching your inbox.
To add or remove addresses:
- Open Email Accounts and choose the mailbox
- Go to Spam Settings
- Add the desired email or domain to the allow or block list
5. DKIM and Authentication
SiteForge automatically manages DKIM signing and SPF alignment for your domain.
These mechanisms improve message deliverability and verify that emails are truly sent from your authorized mail servers — reducing the risk of spoofing and phishing.
Best Practices
- Review your spam folder regularly. Legitimate messages may occasionally be flagged.
- Whitelist important senders (such as clients, suppliers, or your own domains).
- Avoid publishing your email address publicly on websites to reduce spam exposure.
- Enable two-factor authentication (2FA) on your Webmail account for enhanced security.
- Keep thresholds balanced: Too strict → false positives. Too lenient → spam overload.
- Never click suspicious links in unknown emails, even if they appear to come from trusted sources.
Example Configuration (Recommended)
| Setting | Recommended Value | Description |
|---|---|---|
| Spam Folder Threshold | 4 | Aggressive spam detection, safe for most users |
| Reject Threshold | 8 | Blocks messages with very high spam score |
| Greylist Threshold | 6 | Defers suspicious messages to verify legitimacy |
| Whitelist | Add trusted contacts | Ensures delivery from important senders |
| Blacklist | Add known spam sources | Prevents recurring spam messages |
Summary
Spam filtering in SiteForge Email is designed to be flexible, giving you complete control over how aggressively unwanted mail is filtered.
By combining folder thresholds, rejection rules, greylisting, and custom allow/block lists, you can achieve a balance between security and convenience.
