Spam filtering scores each incoming message and moves likely spam out of your inbox. How you adjust it depends on where your mailbox is.
Business Email: spam filtering is on automatically. Likely spam is filed to Junk Mail, never deleted. You can add your own rules in webmail. DirectAdmin hosting mailboxes: use SpamAssassin in DirectAdmin to set how strict the filter is and what happens to spam.
1. Business Email
Every incoming message is scored, and anything that looks like spam goes to your Junk Mail folder. Nothing is bounced or silently deleted, so check Junk if you are expecting a message.
- Mail landed in Junk by mistake: move it back to your Inbox. To keep a sender's mail out of Junk, create a filter rule in webmail that files their messages into your Inbox.
- Sort or block senders: use Mail filters and rules in webmail (at
https://mail.stardomain.com) to move, label or delete messages by sender, subject or other fields. - Viruses: incoming mail is also scanned, and infected messages are refused.
2. DirectAdmin hosting mailboxes
- Log in to DirectAdminand open E-Mail Manager › SpamAssassin Setup.
- Turn SpamAssassin on.
- Set the threshold.The default of 5 suits most people. Lower numbers catch more spam but risk catching real mail.
- Choose where spam goes.Sending it to a spam folder is safer than deleting it.
- Add allowed and blocked sendersif you need them, then save.
3. Good habits
- Check Junk or Spam now and then for real mail, especially after a change.
- Don't reply to spam or click "unsubscribe" in messages you never signed up for.
- Set up SPF, DKIM and DMARC for your own domain, so your outgoing mail is not treated as spam elsewhere. See Understanding SPF, DKIM, and DMARC Records.
Is spam filtering included with Business Email?
Yes. It is on for every mailbox. Spam is filed to Junk Mail, not deleted.
Can I change the spam threshold on Business Email?
The threshold is set on the server. You control what happens to messages with your own filter rules in webmail. If spam regularly gets through, or real mail regularly lands in Junk, open a ticket with an example.
Why does real mail go to Junk?
Usually the sender's domain is missing SPF, DKIM or DMARC records. Move the message back to your Inbox, and ask the sender to fix their records.
