We offer Cloud customers access to an advanced anti-spam solution, which allows users to modify various anti-spam settings from within the Console.
Below are instructions on how to access the Cloud Anti-spam interface, and how to use its various functions, for spam options on cPanel use this guide.
- Log in to the Admin Panel
- Hover over 'Domains' and click 'Manage'
- Click on the domain you want to edit
- Click Email
- Click Manage Anti-Spam & Email Archiving
Note: It is also possible to modify anti-spam options per email address; however, the options available per email address are limited, so we recommend that users make changes at the domain level instead.
Emails which are identified as spam by our Cloud Anti-spam filtering system will be redirected to quarantine. These emails will not arrive in the recipient’s inbox unless manually released by the user from within the quarantine interface. Once in quarantine, users have the option to either release or delete any email which has been marked as spam.
- Click on the Spam quarantine icon
- Locate the email you wish to release or delete
- Click on the release or delete icon
The Cloud Anti-spam filtering system will scan the email content of a message based on a combination of advanced statistical filtering technologies, spam fingerprint databases, viruses, phishing, and spyware. Email detected as spam is either temporarily rejected (4xx error code) or permanently rejected (5xx error code), depending on the total score. Emails which are permanently rejected at this level are quarantined and available for release (except for viruses). In case a legitimate email is permanently blocked, the system will inform the sender that the email did not arrive.Block attachments
One common way for malicious users to spread viruses is via attachments. Users may configure their account to block emails that contain specific file attachments which may hold malicious content. To add file extensions to the block list, follow the instructions below.
- Click on the 'Blocked extensions' icon
- Click 'Add extension'
- Type in the name of the extension you wish to block in the field provided
- Click [Add]
- Email size limit
To restrict both incoming and out-going emails which exceed a particular file size, users can navigate to the Email size restriction area and modify their settings.
- Click the 'Email size restriction' icon
- Type in a file size limit (in KB)
- Click [Update]
Black and whitelisting
- Navigate to the Whitelist/Blacklist panel
- Select the type of list you wish to manage
- Add/remove the domain or email address to/from the list
We are currently working on further integration of our Cloud Anti-spam and webmail systems. Once completely integrated, users will be able to report emails as spam or not spam directly from the webmail interface. For the time being, users can manually report specific emails as spam or not spam by exporting their emails from their inbox into .eml files, then uploading the .eml files into the 'Report spam' and 'Report not spam' areas of the Cloud Anti-spam system.
There are several tools available online to export emails into .eml files from various email clients such as Thunderbird and Outlook.
Users may search through the past 28 days of their email logs. This can help users identify whether an email was received, and whether it was rejected or accepted by the server. The logs also include information such as the email message ID and sending server name, email address and time the email arrived on the server. To access the email logs, follow the instructions below.
Click on the 'Log search' icon
Select a date range and enter in any other specific details that are relevant to the search you want to perform
Click 'Start search'
If an inbox is full or there is a high load on the server, emails may get held up in the delivery queue prior to arriving in an inbox. The email queue shows emails which have arrived on our server but are being queued for delivery to a specific email address.
Emails generally pass through the delivery queue very quickly, and it is not common to notice any delay.
